Abstract: A wireless ablation catheter assembly including an ablation catheter having a catheter body extending between a proximal end and a distal end with a magnetically-susceptible area defined along the catheter body between the proximal and distal ends. A magnetic field generator is configured to provide a magnetic field to the magnetically-susceptible area such that the magnetically-susceptible area dissipates heat. A method of ablation is also provided.

Abstract: A reconfigurable adaptive wideband antenna includes a reconfigurable conductive substrate for dynamic reconfigurablility of the frequency, polarization, bandwidth, number of beams and their spatial directions, and the shape of the radiation pattern. The antenna is configured as a reflect array antenna having a single broadband feed. Reflective elements are electronically painted on the reconfigurable conductive surface using plasma injection of carriers in high-resistivity semiconductors.

Abstract: A microelectronic mechanical systems (MEMS) switch includes a vane formed over a substrate for electrically coupling an input line to an output line formed on the substrate. The vane includes flexible hinges, which support the vane from the input line and allow the vane to rotate about a pivot axis. The substrate includes pull-down and pull-back electrodes to actuate the MEMS switch. The pull-back electrode allows the present invention to overcome stiction effects.

Abstract: The present invention is a fault tolerant apparatus for regulating the flow of electricity. The apparatus comprises a light radiating circuit which includes a first light source for radiating a first light signal, a second light source for radiating a second light signal and a first light sensor for receiving at least one of the first and second light signals and for generating a first light sensor output signal in response to the first and second light signals. The radiating circuit further includes a control circuit for actuating the first light source to radiate the first light signal when the control circuit receives a control input signal and for actuating the second light source to radiate the second light signal when the control circuit fails to receive the first light sensor output signal from the first light sensor within a predetermined time after the control circuit has received the control input signal.

Abstract: A two-sided light-activatable semiconductor switch device having an optical port on each side thereof. The semiconductor device may be a p-i-n diode or of bulk intrinsic material. A two ported p-i-n diode, reverse-biased to "off" by a 1.3 kV dc power supply, conducted 192 A when activated by two 1 kW laser diode arrays, one for each optical port.
