Abstract: A magazine tube and barrel clamp with integral target illuminator, wherein a laser module can be incorporated is provided for a firearm having a magazine tube and a barrel. The frame defines a clamping sleeve for substantially encircling the magazine tube and a barrel receiving channel for receiving a diameter of the barrel, wherein the magazine tube and the barrel are thus fixed in a predetermined spacing. The frame further defines an illuminator recess for receiving a substantial portion of a reflector in the target illuminator, thereby shielding the target illuminator from contact with external surfaces. A driver circuit is retained within the frame to selectively operate the target illuminator and a laser sight, wherein the target illuminator can be a solid-state light emitting device.

Abstract: A self-contained and encapsulated AC to Voltage supplying module containing a complete set of AC circuitry components therein and directly connecting the components to the AC voltage source, an inrush protection circuit, a DC-DC converter and power control circuits which enable the encapsulation of AC and DC components within a module being directly mountable and DC electrically connected to a printed circuit board assembly.

Abstract: An apparatus for extending USB linkage between a host computer and a peripheral unit includes a first extender port, a second extender port, a first extender cable connected to transmit signals from the first to the second port, and a second extender cable connected to transmit signals from the second port to the first, such that outgoing USB signals from each port are identical to incoming USB signals into the other port. Each port is formed of a driver circuit connected to one extender cable, a receiver circuit connected to the other cable, and an interface circuit including a USB transceiver connected by USB cable to the transceiver of the host or peripheral. A logic device connected between the circuits selectively effects outgoing signals on a USB or extender cable. The extender cables are bundled in a combined cable that includes a power line and a line for speed signals.

Abstract: A laser diode array includes a dielectric block with a "direct bonded" conductor layer. The conductor layer is segmented by diode bar spaces cut through it, and a laser diode bar is positioned in each space. Current through the conductor layer energizes the laser diode bars. In one form, the laser diode array and the conductor layer form a conductor ring surrounding a laser medium which is energized by the laser diode bars. In another form, a coolant flow tube within the conductor ring forms an annular coolant channel around the enclosed laser medium. In still another form, the conductor ring is itself surrounded by coolant channels.
