Abstract: A fuel cell includes a gas diffusion layer (GM) situated between a catalyst layer of the fuel cell and a flow field plate of the fuel cell. The GM has a first region and a second region along a thickness direction of the fuel cell. The first region is adjacent to the catalyst layer and has a first thermal conductivity. The second region is adjacent to the flow field plate and has a second thermal conductivity lower than the first thermal conductivity.

Abstract: A ceiling system which includes support beams, elongated covers that at least partially cove the support beams, and baffles which attach to the support beams. The support beams may have a vertical web portion, a flange portion at a top end of the vertical web portion, and bulb portion at a bottom end of the vertical web portion. The elongated may have a cover body and a cover slot in a top surface of the cover body. The elongated covers may be mounted to the support beams so that the bulb portions of the support beams are located within the cover slots of the elongated covers. The baffles may extend between and be mounted to adjacent ones of the plurality of support beams so that the baffles extends into notches of the elongated covers and the bulb portions of the support beams are located within slots of the baffle.

Abstract: An architectural fixture assembly includes a first beam and a second beam which are configured to be coupled together. The first beam includes a bottom side and first and second sides extending from the bottom side. The first and second sides of the first beam include notches extending upwardly from a bottom end of the first beam. The second beam includes a bottom side and first and second sides extending from the bottom side. The first and second sides of the second include notches extending downwardly from a top end of the second beam. The first and second beams may be coupled together by engagement of the notches of the first beam with the notches of the second beam.

Abstract: A lighting system including one or more light assemblies, each light assembly having a light-producing subassembly with one or more light sources for emitting light upon energization thereof, one or more sensors for sensing a preselected event, and a control subassembly, to control energization of the light source upon the sensor(s) sensing the preselected event. The light assembly also includes an internal communications subassembly, for effecting communications between the sensor and the control subassembly. The lighting system includes a command center, for providing commands to the control subassembly via the internal communications subassembly, and an external communications subassembly, for communicating the commands to the internal communications subassembly.

Abstract: An architectural fixture connection system offers acoustical and aesthetic benefits. This system utilizes modular construction, allowing interconnection of a variety of different beams to form an installation that may attach to a wall or ceiling of a building. This system may be formed of a series of sheets which are formed into beams using securing brackets and attachment brackets, then coupled to one another using a series of joiner brackets. Interconnection between adjacent beams need not be linear, allowing free-form shapes and angles.

Abstract: An architectural fixture assembly including a generally U-shaped first beam having a bottom side, a first side, a second side, and a first end. Interior surfaces of the first, second, and bottom sides of the first beam define an interior portion. A connector includes a plate, and a connection key extending away from the plate. The interior surfaces of the first and second sides each include a generally V-shaped alignment notch disposed generally adjacent to the first end of the beam. The connection key includes a pair of generally V-shaped sides disposed on opposite sides of the connection key, and each generally V-shaped side is configured to slidably engage one of the generally V-shaped alignment notches.

Abstract: A method for manufacturing an architectural panel and an architectural panel made by the method. The architectural panel may be formed from metal, and the method may start with the processing of a flat metal sheet. The method may include punching holes in a particular pattern into the flat metal sheet, bending the flat metal sheet into a particular shape to form a panel that can be hung from an overhead grid or the like, and printing a desired printing pattern onto the panel. The method may also include a step of coating the panel with a powder coating or a liquid-applied paint finish prior to the printing step. The coating step may occur after the punching step and before the printing step.

Abstract: Systems, apparatuses, methods, and computer program products are disclosed for providing app-less rendering in a group-based communication platform interface. An example method includes receiving a command indicative of a request to perform an app-less API call in the group-based communication platform, wherein the command comprises electronic information indicative of a requested API method name and a set of requested call parameters. The example method further includes generating an app-less API call based on the requested API method name and the set of requested call parameters. The example method further includes generating a response to the app-less API call. The example method further includes generating an app-less API call response message based on the command and the response to the app-less API call. Subsequently, the example method includes generating an ephemeral command response message based on the app-less API call response message.
