Abstract: A fiber optic switch includes a plurality of optical modules that selectively direct light between optical fibers. Each optical module includes an optical fiber, and a light beam steering mechanism for directing light from or to an optical fiber. A processor within the optical module, and an optical detector form a control circuit such that each optical module can align light from fibers within the optical switch. In one embodiment, the beam steering mechanism includes one or more piezoelectric motors that position lenses in front of an optical fiber. The capacity of the fiber optic switch can be increased or decreased by adding or removing optical modules from the switch.

Abstract: An optical switch includes a number of input modules each of which have an optical fiber, one or more lenses bonded to the fiber, and a gimbaling mechanism that selectively aligns the optical module. In one embodiment of the invention, each of the modules and associated gimbaling mechanisms is individually replaceable in the optical switch. In one embodiment of the invention, the optical modules are fitted in spheres that are positioned by motors that move push rods to engage an annular flange surrounding the sphere. In other embodiment, motors rotate the spheres directly to gimbal the optical modules.

Abstract: A battery pack for an electrical device contains rechargeable batteries for supplying power to the electrical device and a transformerless pulse charging circuit. The pulse charging circuit generates a pulse charging current from received AC current, and charges the rechargeable batteries with the generated pulse charging current. A semiconductor switch (12) generates the pulse charging current from the received AC current and supplies the pulse charging current to the batteries. A ramp generator circuit (14) generates a linearly rising waveform beginning at each zero crossing of the rectified AC current. A current sense amplifier circuit (15) measures the average value of current pulses through the battery and generates a signal proportional to an average charging current. A triggering circuit (18) generates the gate firing pulses for the semiconductor switch (12) according to the linearly rising waveform and the average charging current amplifier waveform.
