Abstract: A noise abatement system includes a processor configured to measure noise in an imaging system and generate a switch mode power supply (SMPS) input signal based on the measured noise and an adjustable switched mode power supply configured to receive the SMPS input signal and adjust a switching frequency of the switched mode power supply, based on the SMPS signal, to operate at a frequency that generates harmonics that are outside of an imaging bandwidth of the imaging system. A system and calibration method are also described herein.

Abstract: A high density of electrical interconnection together with well controlled electrical transmission characteristics, low emissivity from the cable and low susceptibility to external electromagnetic interference are obtained in a PET machine with an interconnection harness formed of a ribbon cable with an inner and outer shield. The inner shield together with alternate conductors of the ribbon cable provide a signal return and the outer shield provides an earth ground reducing the susceptibility of the conductors to external electrical noise and reducing emissions from the cable.

Abstract: Improved implantable devices for electro-acupuncture are described. The devices include a flexible conductor electrode, an anchor fixation for preventing motion of the device in tissue after implantation, and/or a sealed, liquid-impermeable housing.

Abstract: An external transmitter assembly for powering and controlling an implanted medical device, wherein a battery drives first and second power supplies that energize a modulation circuit and an amplifier, respectively, to apply programmed current pulses to a transmitting antenna. The second power supply is output limited and couples through holdup capacitors and a filter network to the amplifier, allowing momentary high current operation without affecting oscillator or modulation portions of the circuit.

Abstract: An electro-nerve stimulator system includes a pulse generator for generating current pulses with a transcutaneous patch and percutaneous needle for delivering current pulses to selected stimulation sites. The stimulator is a small battery operated external device that allows adjustment of stimulation levels and interfaces, via a connector, to the trans-percutaneous cable. The transcutaneous electrode is attached to the skin distal from the desired stimulated nerve site. A percutaneous needle is inserted close to the internal nerve site. Stimulation current pulses are designed to flow between the transcutaneous electrode and the internal percutaneous needle. The field generated at the needle site causes the nerve to fire.
