Abstract: The rear cover of an electronics device is made up of two sections including an external heat sink and a rear cover frame. The electronics for the computing device are directly coupled to the heat sink section. The two sections are fastened together with a layer of cushioning material to simultaneously provide shock-vibration protection as well as efficient cooling of the electronics.

Abstract: A charger appliance configured to determine a no-load, disconnected state from an electronic device having a rechargeable battery, and configured to determine a connected state of the charger with an electronic device in which recharging power may be supplied through the charger to the electronic device. Automatic connection and disconnection of a mains power supply is made depending on the detected state of the charger to avoid wasteful energy consumption in a no-load state. State detection may be determined by monitoring a voltage on one or more signal lines associated with the electronic device.

Abstract: Systems and methods for providing message communication among multiple communication gateways. In particular, systems and methods for providing non-voice message delivery to intended recipients with increased speed and reliability to multiple users on multiple platforms. The systems and methods relate to non-voice messaging to multiple messaging gateways. In at least one embodiment, the systems and methods include Internet based electronic messaging using a messaging subsystem configured to optimize text message delivery to communication gateways.

Abstract: A bracket is disclosed for mounting an electrical box on a mounting bar. The bracket comprises a front jaw and a rear jaw. The jaws are movable toward an open position for allowing movement of the bracket relative to the mounting bar and toward a closed position for gripping the mounting bar at a selected position along the mounting bar. The jaws are biased toward the closed position. An electrical box is attached to the front jaw. In one embodiment, the front jaw, rear jaw and a spring for urging the jaws closed are integrally formed from a single piece of sheet metal.

Abstract: A load control device for improving energy efficiency of a heating, ventilating, and air-conditioning (HVAC) system by controlling shed times of a compressor of the HVAC system. The load control device includes a compressor cutoff switch, a sensing circuit, and a processor. The processor determines a subsequent mandatory shed time based upon a previous shed time, a previous run time, and a minimum run time. A subsequent mandatory shed longer than the previous mandatory shed time causes a subsequent run time to be increased, thereby increasing system efficiency.

Abstract: In a wireless multi-hop network, packet routing paths are determined for a first node device based on passive measurement of data messages over a wireless link formed between the first node device and a neighboring second node device. The first node device transmits a first data message to the second node device via the wireless link. At least one of the first node device and the second node device monitors at least one transmission performance parameter corresponding to only a selected subset of frames of the first data message. The selected subset of frames has structural similarity to selected subsets of frames of other data messages communicated and monitored by other node devices of the network. A link cost associated with the wireless link is determined based on at least one transmission performance parameter value produced as a result of the monitoring, which can be used to update the packet routing paths.

Abstract: A magnetic component and a method for manufacturing a low profile, magnetic component. The method comprises the steps of providing at least one sheet, coupling at least a portion of at least one winding to the at least one sheet, and laminating the at least one sheet with at least a portion of the at least one winding. The magnetic component comprises at least one sheet and at least a portion of at least one winding coupled to the at least one sheet, wherein the at least one sheet is laminated to at least a portion of the at least one winding.

Abstract: A modular fuse holder includes a cover that is movable from a closed position to an open position relative to a base along two different paths of motion to prevent inadvertent opening or closing of the cover.

Abstract: Magnetic components including pre-formed clips are described that are more amenable to production on a miniaturized scale. Discrete core pieces can be assembled with pre-formed coils and physically gapped from one another with more efficient manufacturing techniques.

Abstract: Lighting assemblies or lighting fixtures suitable for use in a hazardous location are provided. Generally, the lighting fixtures include a light source assembly, a heat sink, a driver housing or gear module, and a conductive sealing member between the light source assembly and the heat sink. The conductive sealing member has a thermal conductivity of at least about 6 Watts per meter-Kelvin, and/or a thermal impedance of less than about 0.21 degree-C. inch squared per Watt. The lighting fixtures have controlled directional heat transfer from the light source assembly to the exterior of the lighting fixture, while minimizing the heat transferred to the driver housing.

Abstract: Low profile, shielded magnetic components for circuit board applications include self centering core and coil assemblies with coil receptacle and centering projections formed in core pieces that are assembled around a preformed coil. Welding and plating techniques for forming termination structure for the preformed coil avoid thermal shock issues. External gapping elements and agents to form a gapped core structure are avoided, and gap size in the cores may be tightly controlled over large production lot sizes.
