Abstract: A cladding system for a building structure. The system includes a multilayered panel and at least one fastener including a base portion securable to the frame, and a barbed portion projecting from the base portion for penetrating at least a rear face and backing layer of a section of the panel. The barbed portion includes a cental planar member with barbs extending laterally to each side of the central planar member and is sized such that the front face of the panel is not penetrated by the fastener when the panel is secured to the wall frame.

Abstract: A charge pump can be used with a bus-powered device connected to a bus. The charge pump is formed of a power connection from the bus carrying a DC power signal constrained to not exceed a given current limit and a given voltage limit, a DC-to-DC step-down voltage converter, a capacitor, and a DC-to-DC step-up voltage converter. The step-down converter has an input connected to the power connection and produces an intermediate signal having a voltage the same or less than the voltage of the power signal. The capacitor is connected to the output of the step-down converter. The step-up converter has an input connected to the output of the step-down converter and to the capacitor, and produces a final output signal having a voltage greater than the given voltage limit. The output of the step-up converter is connected to and provides DC power to the device.

Abstract: A patch antenna may be integrated into a mobile terminal by associating the patch antenna with a ground plane adapted to remove eddy currents and isolate the antenna from spurious electromagnetic signals. The patch antenna may comprise a kink. Together the patch antenna and ground plane form a surface on which other electrical components may be mounted, such as the transceiver circuitry of the mobile terminal.
