The plenum is the space used for air circulation for heating and air conditioning systems, by providing a location for ductwork. Space between the structural ceiling and the dropped ceiling or under a raised floor is typically considered plenum. Some drop ceiling designs create a tight seal that does not allow for airflow and therefore may not be considered a plenum air-handling space.

(or drop-out) ceilings allow the installation of a dropped ceiling beneath existing fire sprinklers because the tiles, sometimes called melt-out ceiling tiles, are heat sensitive and designed to fall from the dropped ceiling suspension grid in the event of a fire, allowing the sprinklers to do their job. Drop out ceiling tiles can add to the aesthetic appeal of a ceiling since the fire sprinklers are hidden by the tiles. Commonly made from vinyl or expanded polystyrene, drop out ceiling tiles are available in multiple sizes and finishes from a variety of manufacturers. Installation is subject to the local Authority

Drop out ceilings have a further advantage in that they can be mounted underneath fire sprinklers, thus hiding the sprinklers for a more attractive appearance. When installed underneath fire sprinklers, certain requirements for materials, applications, installation, and maintenance of drop out ceilings must be met in order to comply with fire safety regulations.

Drop (telecommunication) In a communications network, a drop is the portion of a device directly connected to the internal station facilities, such as toward a telephone switchboard, toward a switching center, or toward a telephone exchange. A drop can also be a wire or cable from a pole or cable terminus to a building, in which case it may be referred to as a downlead. These cables may be reinforced to withstand the tension (due to gravity and weather) of an aerial drop (i.e., hanging in air), as in "messenger" type RG-6 coaxial cable, which is reinforced with a steel

undulations throughout the duct route. Therefore, for microducts, Air-Blown (AB) cable installation techniques are expected to be the most useful. AB cable installation requires the use of a device that injects a high volume of air into the duct, at pressures as high as 20-25 psi. The viscous drag forces generated by the rushing air along the length of the cable act to reduce or overcome the friction between the cable and the duct. For telecommunications, cables can be installed in water, in air or underground. In the latter case, the cables might be direct buried or installed in ducts.

are even older as radio programming was distributed by cable in some European cities as far back as 1924. To receive cable television at a given location, cable distribution lines must be available on the local utility poles or underground utility lines. Coaxial cable brings the signal to the customer's building through a "service drop", an overhead or underground cable. If the subscriber's building does not have a cable service drop, the cable company will install one. The standard cable used in the U.S. is RG-6, which has a 75 ohm impedance, and connects with a type F connector. The

this low-loss cable was no longer suitable. The new RG6 still performed well at high frequencies because of the skin effect in the copper cladding. However, the aluminium shield had a high DC resistance and the steel core an even higher one. The result is that this type of cable could not reliably be used in satellite TV installations, where it was required to carry a significant amount of current, because the voltage drop affected the operation of the low noise block downconverter (LNB) on the dish. A problem with all the aforementioned cables, when passing current, is that electrolytic

This eliminates the need for twisting during installation, as is required with safety wire. Several companies manufacture safety cable, and it is becoming an industry standard due to easier control of critical inputs and reduced installation time. Installation and quality requirements of safety cable are governed by SAE AS4536. One system works by providing pre-cut lengths of safety wire that have a large cap on one end.

(The required cable size depends on the length of the bus, up to a maximum of 300 m with (15.4 AWG) conductors.) Each bit is sent Manchester coded (half a bit time of the data bit, followed by half a bit time of its complement), so that power is present for half of each bit time. When the bus is idle, it is high voltage all the time, which is not the same as a "0" or a "1" data bit.

Furthermore, most of the available cable clamps are not very flexible when it comes to routing lines with varying diameters. That causes higher acquisition and storage costs. The installation of the single cable clamps can take a lot of mounting time, depending on the laying length of the lines.

The new stores also were decorated in soft blues and greys, had track lighting, and low hanging lights over the greeting cards, all which gave the store a "soft" appearance. Revco introduced strict rules about having no handwritten signs or merchandise displays sitting directly on the floor, which it thought gave the stores a cleaner look. It also required its employees to dress extremely professionally, with men wearing ties.

sufficient insulation is not practical then a driven shield will improve performance. Coaxial cable is well suited for use as a guard, if electromagnetic shielding is also required then triaxial cable should be used as depending on the type of buffer circuit any noise on the guard may be amplified in the output. The limiting factor for this method is the input impedance of the voltage buffer, the JFET or CMOS op-amps typically used may have input impedances of many teraohms which is sufficient for most applications. Care must also be taken to ensure there are no significant gaps in

The building's interior was largely dismantled, with some of the architectural elements being numbered and stored. After a steel infrastructure was installed, those elements were restored in their original configuration. The Red Room was dismantled and reconstructed during this period. Installation of air conditioning in 1953 and 1954 required the ceiling height be reduced by approximately 18" and a new plaster ceiling with a somewhat generic pattern of stars was installed.

Also, testing allows for quick response to high blood sugar (hyperglycemia) or low blood sugar (hypoglycemia). This might include diet adjustments, exercise, and insulin (as instructed by the health care provider). A blood glucose meter is an electronic device for measuring the blood glucose level. A relatively small drop of blood is placed on a disposable test strip which interfaces with a digital meter. Within several seconds, the level of blood glucose will be shown on the digital display. Needing only a small drop of blood for the meter means that the time and effort required for testing is reduced

The cost of small fiber-count pole-mounted cables has greatly decreased due to the high demand for fiber to the home (FTTH) installations in Japan and South Korea. Fiber cable can be very flexible, but traditional fiber's loss increases greatly if the fiber is bent with a radius smaller than around 30 mm. This creates a problem when the cable is bent around corners or wound around a spool, making FTTX installations more complicated. "Bendable fibers", targeted towards easier installation in home environments, have been standardized as ITU-T G.657. This type of fiber can be bent with a radius as low

often used in telecommunications. The minimum bending radius will vary with different cable designs. The manufacturer should specify the minimum radius to which the cable may safely be bent during installation, and for the long term. The former is somewhat larger than the latter. The minimum bend radius is in general also a function of tensile stresses, "e.g.," during installation, while being bent around a sheave while the fiber or cable is under tension. If no minimum bend radius is specified, one is usually safe in assuming a minimum long-term low-stress radius not less than 15 times the cable diameter,

Cable management Cable management refers to management of electrical or optical cable in a cabinet or an installation. The term is used for products, workmanship or planning. Cables can easily become tangled, making them difficult to work with, sometimes resulting in devices accidentally becoming unplugged as one attempts to move a cable. Such cases are known as "cable spaghetti", any kind of problem diagnosis and future updates to such enclosures could be very difficult. Cable management both supports and contains cables during installation, and makes subsequent maintenance or changes to the cable system easier. Products such as cable trays, cable

With mains voltages of around 220 V, the power dissipated by the additional resistance and the voltage drop across it could be quite high, and it was common to use a resistive power cable (mains cord) of defined resistance, running warm, rather than putting a hot resistor inside the case. If a resistive power cable was used, an inexperienced repairer might replace it with a standard cable, or use the wrong length, damaging the equipment and risking a fire. AC/DC

There were several reasons for not testing a Little Boy type of device. Primarily, there was insufficient uranium-235. Additionally, the weapon design was simple enough that it was only deemed necessary to do laboratory tests with the gun-type assembly. Unlike the implosion design, which required sophisticated coordination of shaped explosive charges, the gun-type design was considered almost certain to work.

The only likely situation in which this might occur is during decompression after deep-sea diving. A pressure drop as small as 100 Torr (13 kPa), which produces no symptoms if it is gradual, may be fatal if it occurs suddenly. Such an incident occurred in 1983 in the North Sea, where violent explosive decompression from nine atmospheres to one caused four divers to die instantly from massive and lethal barotrauma.
