Abstract: System and method provide wireless distributed lighting control systems implementing a secure peer-to-peer, self-organizing and self-healing mesh network of actuators and system inputs. The system and method can be designed specifically for indoor and outdoor lighting where actuators include in-fixture, on-fixture and circuit control modules with ON/OFF and full range dimming capabilities, and system inputs include occupancy/vacancy sensors, daylight sensors and switches. A unique messaging protocol facilitates wireless and wired communication between actuators and system inputs, and provides web-based commissioning and monitoring of the lighting control system using a wireless access point accessible from a local network or Internet which can provide an intuitive and easy to use Graphical User Interface (GUI).

Abstract: A lane divider for fitting to a shelf having front and rear rails, including at least one elongated loop having front and rear ends and a member affixed to each of the front and rear ends of the elongated loop, the member including a face for engaging the front and rear rails, respectively, of the shelf, whereby when the elongated loop is dimensioned to be positioned with the faces of the members respectively engaging the rails.

Abstract: A fluorescent lamp lens assembly for commercial display refrigerators, the fluorescent lens assembly being generally tubular in configuration and including a length generally approximating the length of the fluorescent lamp. The fluorescent lamp is positioned into the lens assembly and held in concentric relation therein by means of a pair of end caps securing the fluorescent lamp within the tubular lens. Both of the caps allow the terminal pins of the fluorescent lamp to extend outwardly allowing the pins to connect to the lamppost of a conventional fluorescent lamp fixture. One of the ends (e.g., the top end) is provided with a removable cap allowing a spent lamp to be removed therefrom and replaced with a new one.

Abstract: A method for handling alarm conditions from paging stations in a paging system is disclosed. The paging system includes a paging terminal, a plurality of paging stations, and a network manager. When a paging station has an alarm condition, the paging station forwards the alarm to the network manager, which in turn compares the alarm with an alarm record for that paging station and determines whether or not that alarm is a higher priority than the previous alarms received from the paging station. If so, the network manager transmits a signal to the paging terminal to page the technician responsible for servicing that particular paging station. The technician is paged and dispatched to the paging station for service.

Abstract: A window structure (10) having an exterior side (12) and an interior side (14). The window structure (10) includes a stationary casing (22) closed by a movable sash (26) that is fastened to the stationary casing (22) in hinged relation. The stationary casing (22) has an exterior panel (28) located exterior to the sash (26) and extending over the sash (26) to overlap its periphery. A gasket (30) is fastened to the exterior panel (28) and faces interiorly, generally toward the sash (26). The sash has an exteriorly facing mounting surface (40), and a glazing support member (42) extends exteriorly therefrom. A window lite (46) is mounted in spaced relation to the mounting surface (40). The window lite (46) has an exterior surface (48) that engages the gasket (30) in sealing relation when the sash (26) is in its closed position and an interior surface (49) facing the mounting surface (40).

Abstract: A wall opening frame member (10, 79) for framing doors, windows, and the like having an exterior side (14) and an interior side (16). The frame member (10) has a metal frame (18) that preferably has at least one structural heat transfer barrier (52, 62) whereby no unbroken metallic heat transfer path exists between the exterior side (14) and the interior side (16). A wood facing (20) is adapted to cover all substantial interior surfaces of the metal frame (18) when the metal frame (18) is in use. Means are provided for attaching wood facing (20) to the interior surfaces of the metal frame (18) so that no substantial surface of the metal frame (18) is exposed to the inside ambient air and the transfer of heat between the exterior side and the interior ambient air of the frame member (10) is inhibited.

Abstract: A glazed wall construction system is disclosed in which all the interior metallic structural elements of the wall system are thermally isolated from the exterior air and from all other metallic components which are in contact with the exterior air. This isolation is accomplished by a separator (56) which covers a boss (36) provided on the structural frame member (34) and by a special fastener (42) which has a non-metallic head (64) molded on it so that it can fasten an exterior cover (40) to the system without serving as a conduit for heat.

Abstract: A thermal break ventilator unit designed to extend between the opposed end jambs of a window frame. The thermal break ventilator unit has a box-shaped body with a ventilating passage therethrough. Essentially cylindrical, opposed raceways are attached to the opposed end jambs within the box-shaped body. A substantially drum-shaped closure unit rotates within the opposed raceways. The closure unit has a closed position wherein the ventilating passage is closed and an open position wherein the venilating passage is substantially unrestricted by the closure unit. Structural heat transfer barriers are incorporated into the metallic parts of the thermal break ventilating unit and are so located that, when the closure unit is in its closed position, there is no continuous, metallic path by which heat can flow between the interior and exterior parts of the ventilator unit.
