A wireless sensor for a load control system is adapted to be releasably mounted to a surface, such as a drop ceiling panel, to allow the optimum location of the sensor to be determined. A releasable mounting means of the sensor comprises two posts extending perpendicularly from a rear surface of the sensor. Each post has a small diameter and is rigid enough to pierce the panel without creating a large aesthetically-displeasing hole. The sensor may be permanently affixed to the panel by bending the posts at a rear surface of the panel without the use of a tool, such that the panel is captured between the mounting plate and the deformed posts. The sensor further comprises multiple test buttons provided on an outwardly-facing surface of the sensor for separately testing the communications of the load control system and the operation of the sensor. Alternatively, the releasable mounting means may comprise one or more magnets for magnetically coupling the sensor to a grid structure of the ceiling.

A low-clearance lighting includes a plurality of light emitting diodes positioned on at least two side surfaces of a light tile or a plurality of external electrode fluorescent lights within an encasement of a light tile, a reflecting plate at a back surface of the light tile, and a metal frame for supporting the light tile and having exterior dimensions suitable for insertion into a ceiling-grid of a drop-ceiling.

A thermal management cabinet for electronic equipment such as servers, having an opening in the top and bottom of the cabinet. The cabinet extends between a raised access floor of a building carrying cooled air and a drop ceiling for venting heated air. The bottom opening of the cabinet is alignable with an opening in the access floor such that cool air can pass into the cabinet and can flow through the electronic component storage area to the top opening, which is alignable with an opening in the drop ceiling. The cabinet interior is separated into temperature zones comprising at least a cold zone supplied with air from the access floor and a hot zone for venting through the top opening. At least one baffle creates the temperature zones such that air is directed to flow from the cold zone through the electronic component storage area to the hot zone.

A perimeter clip attached to a wall molding that supports a beam in a suspended ceiling intended to survive seismic disturbances. The clip is capable, during an earthquake, of permitting an end of a beam at one end of a connected line of beams, in a grid, to slide while being supported in the clip, or, in the alternative, to secure an end of a beam to the wall molding.

A T-bar clip assembly that securely couples to T-bar structures that are used to construct suspended ceiling is disclosed. The T-bar assembly is configured to support one or more electrical fixtures and provide power feeds to the one or more electrical fixtures. The T-bar clip assembly comprises support brackets that secure to the T-bar structures and one or more housing structures that attach to a portion of the support brackets to form one or more corresponding junction box enclosures. The junction box enclosures provide the power feeds to the one or more electrical fixtures at locations that are substantially flush with support flanges of the T-bar structure, an outer surface of the removable ceiling tiles or both.

A panel for use in a drop ceiling system, or with appropriate modification, a wall, wherein the ceiling system includes stringers and cross-members defining areas therebetween for support of the panels wherein the panels include at least one planar sheet of material secured to a reinforcement member having channels formed therein to extend in at least one direction relative to the sheet material. When more than one sheet of material is used, the sheets of material are disposed on opposite sides of the reinforcement member. The panels are flexible for easy insertion into the openings between the stringers and cross-members of the support system and are readily compressed into a thinner profile for shipping purposes.

A UV air cleaning and disinfecting system has an enclosed chassis with an inlet / outlet surface panel on one planar side thereof, and the chassis is mounted in the space behind a drop ceiling with its surface panel coplanar with the ceiling surface and facing into the room space. The surface panel has a pair of inlet vent arrays on opposite longitudinal sides of the surface panel from each other, and a pair of outlet vent arrays on opposite latitudinal sides of the surface panel from each other. Arranged in the chassis are an air blower unit and an array of UV lamps. The positioning of the inlet and outlet vent arrays establish four mutually circulating air streams in a four-leaf-clover pattern in the room space, which obtains a high-efficiency throughput of air handled by the system. The UV lamp array is arranged longitudinally across the chassis between the inlet ventsat a lower elevational position of the chassis. A pair of air filters is arranged at intake chambers separated by UV-blocking baffles at opposite longitudinal sides of the main chamber housing the air blower in the center of the chassis at an upper elevational position from the array of UV lamps. The upward and downward movement of the air through the filters and over the UV lamps toward the center causes swirling movements which enhance the exposure of pathogens in the air to UV radiation exposure. The surface panel is formed with a series of cascading door sections to allow wide access across the center of the chassis for maintenance of the UV lamps, with a first door section connected to an interlock switch for cutting off electrical power to the UV lamps and fan when the first door section is opened. The UV-blocking baffles have an angled shape and slits at an upper flange thereof covered with fused silica shields. The system's chassis is dimensioned to fit on ceiling rails spaced at standard 4 foot length and 2 foot width intervals. The system can provide 99% or higher inactivation of pathogens in the air with 2 to 7 or more air changes per hour for standard sized rooms.

A disposable air filter and grill assembly is disclosed which eliminates the undesirable need of cleaning conventional air filter grills. The assembly includes a frame which can be mounted within a grid of a drop ceiling or other opening loading to a space to be heated and / or cooled. The frame includes a plurality of clips to removably secure a disposable filter unit therein. The disposable filter unit includes an outer shell within which filter media is positioned. After the unit has been used a sufficiently long period of time and needs to changed, the clips can be disengaged, the disposable filter unit can be removed, and a new unit can be installed. Accordingly, as opposed to cleaning existing grills which often result in a less than properly maintained facility or an aesthetically undesirable facility, the apparatus disclosed herein provides an aesthetically pleasing, functional, and easily maintained system.
