TKP is a tobacco company from PrilepRepublic of Macedonia. This tobacco company from Prilep deals mainly with the purchasing and selling of high quality oriental tobacco (types Prilep and Yaka); its operations also include the production of cigarettes. The Prilep region is known for its production of quality oriental tobacco. Tobacco tradition in Prilep goes back to 1873 when R.O.T (Regie Ottoman de Tabak) built the first warehouse for purchasing and processing tobacco. In 1930 the Croatian scientist Rudolf Gornik introduced the first varieties of famous oriental type Prilep and heralded the beginning of a golden tobacco era in Prilep. The then Government of Yugoslavia issued a special resolution in 1949 which established a state-owned Tobacco company in Prilep. Primary aims of this trading company were the purchasing and processing of tobacco. Soon Prilep's "gold" brought the first money in ex-Yugoslavia from abroad. Trade was established with USAJapan, and companies in Europe. In 1955 the Tobacco company from Prilep opened its first cigarette factory.

Certified Color Standards

Effective color communication is essential to the of textile industry. The ability to create, produce and reproduce the exact color cannot rely solely on a visual comparison. A color’s appearance is based on three elements, huechroma and value. The hue is how one perceives an object’s color, while chroma is based on the vividness or dullness of a color and value is the color’s degree of lightness. These three criteria are all perceived by the eye but any differences are not detected equally among the three. In addition poor color memory, eye fatigue and previous references can affect how color is viewed on an individual basis.
Over the past few years there has been a dramatic shift from vertically run companies to separate, specialized design or production facilities. Theglobalization of the textile industry has increased the need for effective color communication. With more steps in the supply chain there is an increased risk of variations of color which in the end can be harmful to the product or brand. Discolored logos, mismatched clothing and other inconsistencies result in losses of sales and revenue.

Measuring Color

To solve the problems that arise with communicating color, a standard must be chosen as a target for comparison purposes. Once the target is specified it is read with a spectrometer to translate it into its numerical values. Then an electronic file containing the standard’s properties along with a visual reference is sent to the mill. The measurement conditions are determined by the brand or retail program accounts and are measured as percentages of reflected light at certain intervals of wavelengths along the visible spectrum and these data points are stored. The visual reference fabric is individually quality controlled to be within the electronic standards. The visual reference is placed in a fold-over color standard format to keep from excessive handling, light exposure, and to assist in visual assessment. Each standard is given a serial numberwhich is unique and traceable to that individual standard. This process limits problems with visual comparisons and reduces the possibility of future miscommunication throughout the supply chain.
There are two scales that are used to measure color, the Munsell scale and the CIE color System. The Munsell scale is based on human perception, assigning a numerical value to the three parts of color (hue, chroma, value). Whereas the CIE color order systems standardizes color by specifying which illuminant is used. The system gathers the percentages of reflected light along the wavelengths of the visible spectrum and creates a reflectance curve with the data which is then applied to a mathematical formula.
For companies that utilize both visual and digital color measurement it is important that their spectrophotometers are certified and profiled, their light box and conditioning cabinets should be properly maintained and their fabric sample measurement procedures should be consistent.

Certified Standards

To make a standard ‘certified’ there are a number of characteristics that it must have after being processed.
  • An additional Quality Control step that spectrally measures each standard, providing increased color consistency
  • Certification & Traceability - each standard is assured to be < 0.50 DEcmc against the spectral master and target illuminants. The quality result of every standard is traceable through bar-coding.
  • Spectral Data Creation - A master spectral file is created for every color and automatically delivered during the ordering process.
  • Web-based Distribution
  • A serial number which allows traceability
  • A reproducible Color Standard a with good dye formula
  • Fold-over Color Standard Format to protect the fabric from light and excessive handling and assist in visual assessment
Fabric produced for color standards must be inspected and pass specific evaluation criteria. These criteria include light sources, visual inspection, spectral tolerances, etc. For certified color standards, a master qtx file (file containing the data to generate the spectral curve) is established. This practice allows the colors to remain consistent from season to season.

Optical landing system


The Fresnel Lens Optical Landing System of Charles de Gaulle
An optical landing system (OLS) (nicknamed "meatball" or simply, "Ball") is used to give glidepathinformation to pilots in the terminal phase of landing on an aircraft carrier.[1] From the beginning of aircraft landing on ships in the 1920s to the introduction of OLSs, pilots relied solely on their visual perception of the landing area and the aid of the Landing Signal Officer (LSO in the US Navy, or "batsman" in the Commonwealth navies). LSOs used colored flags, cloth paddles and lighted wands.

Components

Diagram showing parts of OLS
An optical landing system has several related components: the lights used to give visual cues to approaching aircraft, the light control system, and the mounting system.

Lights

At least three sets of lights are used, regardless of the actual technology:
  • Datum lights — a horizontal row of green lamps used to give the pilot a reference against which he may judge his position relative to the glide slope.
  • Ball (or “meatball”; also known as "the source") — indicates the relative position of the aircraft with reference to glide slope. If the aircraft is high, the ball will be above the datum lights; if the aircraft is low, the ball will be similarly below the datums. The further the aircraft is from the glide slope, the further the ball will be above or below the datum lights. If the aircraft gets dangerously low, the ball appears red. If the aircraft gets too high, the ball appears to go off the top.
  • Wave-off lights — red flashing lamps which, when lit, indicate that the pilot must add full power and go around — a mandatory command. When the wave-off lights are lit, all other lamps are extinguished. The wave-off lights are operated manually by the LSO.
Additionally, some (particularly later) optical landing systems include additional lamps:
  • Cut lights — Green lamps used to signal different things based on where the approaching aircraft is in its approach. Early in a no-radio or "zip-lip" approach (which is routine in modern carrier operations), Cut Lights are flashed for approximately 2–3 seconds to indicate that the aircraft is cleared to continue the approach. Subsequent flashes of the Cut Lights are used to prompt the pilot to add power. The longer the lights are left on, the more power should be added. Cut Lights are operated manually by the LSO.
  • Emergency wave-off lights - Red lamps that have the identical function as Wave-Off Lights, but use an alternate power source. Not normally used.

Light controls

LSOs hold the "pickle", which controls lights on the OLS. The controller is held above the head until the landing area is clear and the arresting gear is set.
Collectively, the apparatus that the lights are mounted on is called “the lens”. It is turned on/off and brightness is adjusted at the lens itself for ground based units, and remotely for shipboard units. In both cases, the lens is connected to a hand-controller (called the “pickle”) used by the LSOs. The pickle has buttons that control the wave-off and cut lights.

Light mounting

For shore-based Optical Landing Systems, the lights are typically mounted on a mobile unit that plugs into a power source. Once set up and calibrated, there are no moving parts to the unit. Shipboard units are much more complicated as they must be gyroscopically stabilized to compensate for ship movement. Additionally, shipboard units are mechanically moved (the “roll angle”) to adjust the touchdown point of each aircraft. With this adjustment, the tailhook touchdown point can be precisely targeted based on the tailhook-to-pilot’s eye distance for each aircraft type.

Mirror landing aid

The rear of the mirror landing aid of HMAS Melbourne. The datum lamps and the two large "wave off" lamps are clearly visible as are, at the left of the photo, four of the orange lamps projected into the mirror to give the "ball".
The first OLS was the mirror landing aid, one of several British inventions made after the Second World Warrevolutionising the design of aircraft carriers. The others were the steam catapult and the angled flight deck. The Mirror Landing Aid was invented by Nicholas Goodhart.[2] It was tested on the carriers HMS Illustrious andHMS Indomitable before being introduced on British carriers in 1954 and on US carriers in 1955.
The mirror landing aid was a gyroscopically-controlled concave mirror on the port side of the flight deck. On either side of the mirror was a line of green coloured "datum lights". A bright orange "source" light was shone into the mirror creating the "ball" (or "meatball" in later USN parlance) which could be seen by the aviator who was about to land. The position of the ball compared to the datum lights indicated the aircraft's position in relation to the desired glidepath: if the ball was above the datum, the plane was high; below the datum, the plane was low; between the datum, the plane was on glidepath. The gyro stabilisation compensated for much of the movement of the flight deck due to the sea, giving a constant glidepath.
Initially, the device was thought able to allow the pilot to land without direction from the LSO. However, accident rates actually increased upon the system's initial introduction, so the current system of including the LSO was developed. This development, along with the others mentioned, contributed to the US carrier landing accident rate plummeting from 35 per 10,000 landings in 1954 to 7 per 10,000 landings in 1957.[3]
The LSO, who is a specially qualified and experienced Navy pilot, provides additional input to the pilot via radios, advising of power requirements, position relative to glide path and centerline. The LSO can also use a combination of lights attached to the OLS to indicate "go around" using the bright red, flashing wave off lights. Additional signals, such as "cleared to land," "add power," or "divert" can be signaled using with a row of green "cut" lights or a combination thereof.

Fresnel lens optical landing system (FLOLS)

Later systems kept the same basic function of the mirror landing aid, but upgraded components and functionality. The concave mirror, source light combination was replaced with a series of fresnel lenses. The Mk 6 Mod 3 FLOLS was tested in 1970 and had not changed much, except for when ship’s heave was taken into account with an Inertial Stabilization system. These systems are still in wide use on runways at US Naval Air Stations.[4]

Improved fresnel lens optical landing system (IFLOLS)

IFLOLS at field
The IFLOLS, designed by engineers at NAEC Lakehurst, NJ, keeps the same basic design but improves on the FLOLS, giving a more precise indication of aircraft position on the glideslope. A prototype IFLOLS was tested on boardUSS George Washington (CVN-73) in 1997 and every deploying aircraft carrier since 2004 has had the system. The Improved Fresnel Lens Optical Landing System, IFLOLS, uses a fiber optic "source" light, projected through lenses to present a sharper, crisper light. This has enabled pilots to begin to fly "the ball" further away from the ship making the transition from instrument flight to visual flight smoother. Additional improvements include better deck motion compensation due to internalization of the stabilizing mechanisms, as well as multiple sources of stabilization from gyroscopes as well as radar.
IFLOLS aboard ship

Manually Operated Visual Landing Aid System (MOVLAS)

MOVLAS Repeater on Integrated Launch And Recovery Television Surveillance System (ILARTS)
The MOVLAS is a backup visual landing aid system used when the primary optical system (IFLOLS) is inoperable, stabilization limits are exceeded or unreliable (primarily due to extreme sea states causing a pitching deck), and for pilot/LSO training. The system is designed to present glideslope information in the same visual form presented by the FLOLS.
There are three installation modes aboard ship: STATION 1 is immediately in front of the FLOLS and utilizes the FLOLS waveoff, datum, and cut light displays. STATION 2 and 3 are independent of the FLOLS and are located on the flight deck port and starboard side respectively. MOVLAS is nothing more than a vertical series of orange lamps manually controlled by the LSO with a hand controller to simulate the ball; it does not automatically compensate for the ship's movement in any way. All MOVLAS equipment is maintained and rigged by the the IC's and EM's within V2 Division of Air Department.

MOVLAS components

MOVLAS is nothing more than a vertical series of orange lamps manually controlled by the LSO with a hand controller to simulate the ball.[5]
Hand Controller
The hand controller is located at the LSO workstation. A handle is provided so the LSO may select the position of the meatball. The pickle switch is attached to the end of the controller handle. As the handle on the LSO controller is moved up or down it lights three or four consecutive lamps in the light box thus providing a meatball.
Repeaters
MOVLAS repeaters show where the LSO is displaying the meatball to the pilot. One repeater is displayed on the Integrated Launch And Recovery Television Surveillance System (ILARTS).

Pitching deck

Point Stabilization from LSONATOPS Manual.
The IFLOLS has two modes of stabilization: line, and inertial. The most precise is inertial stabilization. In line, the glide path is stabilized to infinity. As the deck pitches and rolls, the source lights are rolled to maintain a steady glideslope fixed in space. Inertial stabilization functions like line, but also compensates for the flight deck heave (the straight up and down component of deck motion). If the IFLOLS cannot keep up with the motion of the deck, the LSO can switch to the MOVLAS or simply perform "LSO talk downs." Only the most experienced LSOs will perform talk downs or control aircraft with MOVLAS during heavy sea states.[6]

Biliblanket


A baby being treated for jaundice with a BiliBlanket
biliblanket is a portable phototherapy device for the treatment of neonatal jaundice (hyperbilirubinemia). BiliBlanket is a trademark of General Electric's Datex-Ohmeda subsidiary, but its name has become the generic, colloquial term for a range of similar products and the term used in the medical professions. The name is a combination of bilirubin and blanket. Other names used are home phototherapy system, bilirubin blanket, or phototherapy blanket.
Biliblankets offer the possibility of treating some degrees of jaundice at home as long as the baby is otherwise healthy. This makes them quite popular with parents, doctors, and insurance companies, who would otherwise have to pay for more expensive inpatient treatment. Some also consider it a better option because the newborn does not have to be separated from the parents and does not need to lie alone in a box with his or her eyes covered. The baby is tied to the machine, unless they can wheel it around, and there is a stiff pad between the mother and baby. While this is an inconvenience, most see it as a lesser of two evils.
Phototherapy for jaundice involves a blue/white light of varying intensity placed close to the skin or touching it through a special, light-permeable fabric.
The whole setup consists of the light generator, termed the light box, the fibre-optic cable through which the light is carried and the light pad, which is a 25cmx13cm (10"x5") pad that's attached to the baby. Home phototherapy is not dangerous and reports suggesting that babies have been burned by biliblankets have not been proven, and are generally accepted as myths.

The LD also works closely with the stage manager or show control programming, if show control systems are used in that production. Outside of stage lighting the job of a Lighting Designer can be much more diverse and they can be found working on rock and pop tours, corporate launches, art installation and on massive celebration spectaculars, for example the Olympic Games opening and closing ceremonies.

During pre-production

The role of the lighting designer varies greatly within professional and amateur theater. For a Broadway show, a touring production and most regional and small productions the LD is usually an outside freelance specialist hired early in the production process. Smaller theatre companies may have a resident lighting designer responsible for most of the company's productions or rely on a variety of freelance or even volunteer help to light their productions. At the Off-Broadway, or Off-Off-Broadway level the LD will occasionally be responsible for much of the hands-on technical work (hanging instruments, programming thelight board, etc.) that would be the work of the lighting crew in a larger theatre.
The LD will read the script carefully and make notes on changes in place and time between scenes - such changes are often done just with lighting to avoid too many blackouts in one scene - and will have meetings (called Design or Production Meetings) with the Director, Designers, Stage Manager and production manager to discuss ideas for the show and establish budget and scheduling details. The LD will also attend several later rehearsals to observe the way the actors are being directed to use the stage area ('blocking') during different scenes, and will receive updates from the stage manager on any changes that occur. The LD will also make sure that he or she has an accurate plan of the theatre's lighting positions and a list of their equipment, as well as an accurate copy of the set design, especially the ground plan and section. The LD must take into account the show's mood and the director's vision in creating a lighting design.
Because lighting design is much more abstract than costume or scenic design, it is sometimes difficult for the lighting designer to accurately convey his ideas to the rest of the production team. To help the LD communicate the ethereal aspects of lighting he or she may employ renderings, storyboards, photographs, reproductions of artwork or mockups of actual lighting effects to help communicate ideas about how the lighting should look.
Various forms of paperwork are essential for the LD to successfully communicate their design to various members of the production team. Examples of typical paperwork include cue sheets, lightplots, instrument schedules, shop orders and focus charts.
Cue sheets communicate the placement of cues that the LD has created for the show, using artistic terminology rather than technical language, and information on exactly when each cue is called, so that the stage manager and the assistants know when and where to call the cue. Cue sheets are of the most value to stage management.
The light plot is a scale drawing that communicates the location of lighting fixtures and lighting positions so a team of electricians can independently install the lighting system. Next to each instrument on the plan will be information for any color gelgobo, or other accessory that needs to go with it, and its channel number. Often, paperwork listing all of this information is also generated by using a program such asLightwright. The lighting designer uses this paperwork to aid in the visualization of not only ideas but simple lists to assist the Master Electrician during load-in, focus and technical rehearsals. Professional LDs generally use special computer-aided design packages to create accurate and easily readable drafted plots that can be swiftly updated as necessary. The LD will discuss the plot with the show's production manager and the theatre's master electrician or technical director to make sure there are no unforeseen problems during Load-In.

During installation (Load-In/Focus/Cue to Cue) and technical rehearsals

The lighting designer is responsible, in conjunction with the production's independently hired "Production Electrician" who will interface with the theatre's Master Electrician, for directing the theatre's electrics crew in the realization of his or her designs during the technical rehearsals. After the Electricians have hung, circuited and patched the lighting units, the LD will direct the focusing (pointing, shaping and sizing of the light beams) and gelling (coloring) of each unit.
After focus has occurred the LD usually sits at a temporary desk (tech table) in the theater (typically on the Center Line in the middle of the house) where he or she has a good view of the stage and work with the lighting board operator/programmer, who will either be seated alongside him or her at a portable control console or talk via headset to the control room. At the tech table, the LD will generally use a Magic Sheet, which is a pictorial layout of how the lights relate to the stage, so he or she can have quick access to channel numbers that control particular lighting instruments. The LD may also have a copy of the light plot and channel hookup, a remote lighting console, a computer monitor connected to the light board (so they can see what the board op is doing), and a headset, though in smaller theatres this is less common. There may be a period of time allowed for pre-lighting or "pre-cueing", a practice that is often done with people known as Light Walkers who stand in for performers so the LD can see what the light looks like on bodies. At an arranged time, the performers arrive and the production is worked through in chronological order, with occasional stops to correct sound, lighting, entrances etc.; known as a "cue-to-cue" or tech rehearsal. The lighting designer will work constantly with the board operator to refine the lighting states as the technical rehearsal continues, but because the focus of a "tech" rehearsalis the production's technical aspects, the LD may require the performers to pause ("hold") frequently. Nevertheless, any errors of focusing or changes to the lighting plan are corrected only when the performers are not onstage. These changes take place during 'work' or 'note' calls. The LD only attends these notes calls if units are hung or rehung and require additional focusing. The LD or Assistant Lighting Director (also known as the ALD, see below for description) will be in charge if in attendance. If the only work to be done is maintenance (i.e. changing a lamp or burnt out gel) then the Production or Master Electrician will be in charge and will direct the Electrics crew.
After the tech process, the performance may (or may not, depending on time constraints) go into Dress rehearsal without a ticketed audience and/orPreviews with a ticketed audience. During this time, if the cueing is finished, the LD will sit in the audience and take notes on what works and what needs changing. At this point, the Stage Manager will begin to take over the work of calling cues for the light board op to follow. Generally, the LD will stay on headset, and may still have a monitor connected to the light board in case of problems, or will be in the control booth with the board operator when a monitor is not available. Often, changes will take place during notes call, but if serious problems occur the performance may be halted and the issue will be resolved then.
Once the show is open to the public, the lighting designer will often stay and watch several performances of the show, making notes each night and making desired changes the next day during notes call. If the show is still in previews, then the LD will make changes, but once the production officially opens, normally the lighting designer will not make further changes.
Changes should not be made after the lighting design is finished, and never without the LD's approval. There may be times when changes are necessary after the production has officially opened. Reasons for changes after opening night include: casting changes; significant changes in blocking; addition, deletion or rearrangement of scenes; or the tech and/or preview period (if there was a preview period) was too short to accommodate as thorough a cueing as was needed (this is particularly common in dance productions). If significant changes need to be made, the LD will come in and make them, however if only smaller changes are needed, the LD may opt to send the ALD. If a show runs for a particularly long time then the LD may come in periodically to check the focus of each lighting instrument and if they are retaining their color (some gel, especially saturated gel, loses its richness and can fade or 'burn out' over time). The LD may also sit in on a performance to make sure that the cues are still being called at the right place and time. The goal is often to finish by the opening of the show, but what is most important is that the LD and the directors believe that the design is finished to each's satisfaction. If that happens to be by opening night, then after opening no changes are normally made to that particular production run at that venue. The general maintenance of the lighting rig then becomes the responsibility of the Master Electrician.

In small theatres

It is uncommon for a small theatre to have a very large technical crew, as there is less work to do. Many times, the lighting crew of a small theatre will consist of a single lighting designer and one to three people, who collectively are in charge of hanging, focusing and patching all lighting instruments. The lighting designer commonly works directly with this small team, fulfilling the role of both master electrician and lighting designer. Many times the designer will directly participate in the focusing of lights. The same crew will generally also program cues and operate the light board during rehearsals and performances. In some cases, the light board and sound board are operated by the same person, depending on the complexity of the show. The lighting designer may also take on other roles in addition to lights when they are finished hanging lights and programming cues on the board.

Advances in visualization and presentation

As previously mentioned, it is difficult to fully communicate the intent of a lighting design before all the lights are installed and all the cues are written. With the advancement in computer processing and visualization software, lighting designers are now able to create computer generated images (CGI) that represent their ideas. The lighting designer enters the light plot into the visualization software and then enters the ground plan of the theater and set design, giving as much three-dimensional data as possible (which helps in creating complete renderings). This creates a 3D model in computer space that can be lit and manipulated. Using the software, the LD can use the lights from his plot to create actual lighting in the 3D model with the ability to define parameters such as color, focus, gobo, beam angle etc. The designer can then take renderings or "snapshots" of various looks that can then be printed out and shown to the director and other members of the design team.

Mockups and lighting scale models

In addition to computer visualization, either full scale or small scale mock ups are a good method for depicting a lighting designer's ideas. Fiber optic systems such as Light Box or Luxam allow a users to light a scale model of the set. For example, a set designer can create a model of the set in 1/4" scale, the lighting designer can then take the fiber optic cables and attach them to scaled down lighting units that can accurately replicate the beam angles of specified lighting fixtures. These 'mini lights' can then be attached to cross pieces simulating different lighting positions. Fiber optic fixtures have the capacity to simulate attributes of full scale theatrical lighting fixtures including; color, beam angle, intensity, and gobos. The most sophisticated fiber optic systems are controllable through computer software or a DMX controlled LED Light panel. This gives the lighting designer the ability to mock up real time lighting effects as they will look during the show.

Additional members of the lighting design team

If the production is large or especially complex, the Lighting Designer may hire additional lighting professionals to help execute the design.

The Associate Lighting Designer

The Associate Lighting Designer will help assist the Lighting Designer in creating and executing the lighting design. While the duties that an LD may expect the Associate LD to perform may differ from person to person, usually the Ass't LD will do the following:
  • Attend design and production meetings with or in place of the LD
  • Attend rehearsals with or in place of LD and take notes of specific design ideas and tasks that the lighting department needs to accomplish
  • Assist the LD in generating the light plot, channel hookup and sketches
  • If needed, the Associate may need to take the set drawings and put them into a CAD program to be manipulated by the LD (however, this job is usually given to the Assistant LD if there is one).
  • The Ass't LD may be in charge of running focus, and may even direct where the lights are to be focused.
  • The Associate is generally authorized to speak on behalf of the LD and can make creative and design decisions when needed (and when authorized by the LD). This is one of the biggest differences between the Associate and the Assistant.

The Assistant Lighting Designer

The Assistant Lighting Designer assists the Lighting Designer and the Associate Lighting Designer. Depending on the particular arrangement the ALD may report directly to the LD, or they may in essence be the Associate's assistant. There also may be more than one assistant on a show depending on the size of the production. The ALD will usually:
  • Attend design and production meetings with the LD or the Associate LD
  • Attend rehearsals with the LD or the Associate LD
  • Assist the LD in generating the light plot and channel hookup. If the plot is to be computer generated, the ALD is the one who physically enters the information into the computer.
  • The ALD may run errands for the LD such as picking up supplies or getting the light plot printed in large format.
  • The ALD will help the Associate LD in running focus.
  • The ALD may take Focus Charts during focus.
  • Track and coordinate Followspots (if any exist for the production) and generate paperwork to aid in their cueing and color changes.
  • In rare instances the ALD may be the led light panel operator.

A note on focus

During focus, the LD is up on stage directing members of the Electrics crew on where and how to focus each individual lighting unit. This can be a time consuming and frustrating process. Focus can run much smoother if the Associate LD and the Assistant LD are keeping good track of which lights have been focused, what's coming up next and directing the electrics crew so that there is minimal down time between focusing each light. They should also direct the LD to which units are next and even what their purpose is and a rough focus.
