A system for repeatably mounting an image sensor to a grid ceiling comprising: a mounting member defining an upper face; a set of magnets fixed to the upper face and characterized by a height greater than a protrusion distance of the outer surface of a ceiling tile of the grid ceiling below a grid segment of the grid ceiling; a detachable registration feature transiently coupled to the mounting member, configured to align with the grid ceiling while the set of magnetics are magnetically coupled to the grid ceiling, configured to adhere to the grid ceiling while the set of magnets are magnetically coupled to the grid ceiling, and configured to detach from the upper face and remain adhered to the grid ceiling in response to vertical displacement of the mounting member away from the grid ceiling.

The disclosure relates to support members for ceiling systems, such as those that can be formed into an interconnected grid to be suspended from a ceiling and support ceiling tiles. One aspect of the disclosure is a linearly-extending support member for a ceiling tile. The support member has a cross-sectional shape that includes a substantially vertical central web with a top end and a bottom end; at least one flange extending substantially horizontally from the bottom end of the web, the flange having an upper surface and a lower surface; and a bulb extending from the top end of the web, the bulb having a first side and a second side with a cavity therebetween, the bulb having an upper portion and a lower portion adjacent the top end of the web, wherein the entire lower portion of the bulb is narrower than the upper portion of the bulb and wider than the central web, the bulb comprising a series of spaced apertures formed therein through both the first side and the second side of the bulb, each aperture being disposed at least partially in the lower portion of the bulb, each aperture having an upper portion and a lower portion, wherein the upper portion of the aperture is rounded.

The present invention relates to a suspended ceiling hanger clip and a suspended ceiling formed using the hanger clip. The suspended ceiling hanger clip has a longitudinally extending base having a first end and a second end and a pair of generally parallel co-extensive flanges extending downwardly from the base. At least one projection in each flange is formed with a ramp surface. An aperture is formed in the base for receiving an upper end of the elongate suspension rod therein. The suspension rod has a longitudinal axis extending along a length between spaced apart upper and lower ends, with the lower end having an attachment means. The upper end of the suspension rod extends through and is fixedly retained from removal from the aperture in the base of the hanger clip.

An improved drop/suspended ceiling system which provides consistent spacing between continuous, parallel support rails is described. The rails attach directly to floor joists which permits locating ceiling panels as high as possible with respect to the bottom of the joists. In other embodiments, the rails may be supported by hangers, but held in parallel by spacers hidden by the ceiling panels to avoid the use of conventional suspended ceiling cross-sectional members. In some embodiments, the rails attach within or between joists and can also be used as a remodel or new option. Panels can be used with existing steel drop ceilings in conjunction with the spacer channel to achieve a continuous, parallel look with traditional steel drop ceiling rails using the spacer. Rails and tiles can serve as a direct replacement for traditional tiles or long panels can be used from wall to wall in isles or small rooms.

Described herein is a ceiling system comprising: a support grid; a first panel mounted to the support grid, the first panel comprising a first body formed of a fibrous material; a second panel mounted to the support grid, the second panel comprising a second body formed of a sound attenuation material; whereby the first and second panels are supported by the support grid such that a vertical gap exists between the first panel and the second panel such that the first and second panels are not in direct contact.

A ceiling suspension system is disclosed and includes a plurality of grid members configured to form a grid for the ceiling suspension system, each grid member comprising a bulb, a web and a flange. The system also includes a plurality of wall support brackets configured to mount the grid to walls in a structure. Each wall support bracket comprises a vertical back, a lower flange at a lower end of the vertical back, and an upper flange at an upper end of the vertical back. Further, the upper flange is generally V-shaped when viewed longitudinally and each wall support bracket only one tab in the lower flange for each grid member. Moreover, the only one tab is configured to engage and retain the flange of a respective grid member, such that the respective grid member rests on the lower flange.

In accordance with certain embodiments, systems of lighting components feature multiple illumination panels each having a backing support and, secured thereto, multiple illumination elements. The illumination elements have shapes defined by arrangements of illumination unit cells may be assembled to illuminate an arbitrary two-dimensional area.

Described herein is a coating composition suitable for application to a building panel. The coating composition includes inorganic pigment, liquid carrier, and a humectant including a first ester-containing compound. The liquid carrier may be present in an amount ranging from about 10 wt, % to about 30 wt. % based on the total weight of the coating composition. Described herein are also building panels coated with the coating composition and methods of their production.

Described herein is a ceiling panel assembly comprising a panel body having an inner surface defining an internal cavity having a first open end defined by a first side edge of the panel body, a first end cap comprising a face plate, an insertion portion extending from an inner surface of the face plate, and a concealment portion extending from the inner surface of the face plate; and the first end cap coupled to the panel body so that: (1) the insertion portion extends into the internal cavity; (2) the concealment portion wraps around at least a portion of the first edge and is adjacent an outer surface of the panel body; and (3) the end face plate encloses the first open end of the internal cavity, and the first end cap is coupled to the panel body by frictional fit.
