摘要： The invention relates generally to an improved system for sensing and compensating for external disturbance forces acting on a satellite while in orbit. A proof mass member is housed within an enclosure and shielded from external, non-gravitational forces. The proof mass is electromagnetically levitated to move in a purely gravitational orbit, along an axis aligned with the satellite's velocity vector. The proof mass is subjected to a controlled magnetic biasing field and is caused to have a constant reaction to the resultant biasing force, by means of a thermal control system which maintains constant resistivity of the proof mass, during operation. The position of the proof mass with respect to its axis is detected optically and is utilized to control the firing of spacecraft thrusters. As a result, the satellite is caused to maintain a substantially constant position relative to the proof mass and thereby also is caused to follow a purely gravitational orbit.

摘要： An apparatus for preventing self-injurious behavior in patients is disclosed. The apparatus generally contains one or more sensor modules, which detect self-injurious blows, and a separate stimulation module, which produces an aversive electric stimulation. The sensor module and stimulation module are mounted directly on a patient's body members, e.g., a sensor module can be mounted on a headband worn around the patient's head and the stimulation module can be mounted on an arm band worn around the patient's arm. The sensor module communicates with the stimulation module by either: (1) transmitting radio waves, which are received by the stimulation module or (2) sending a small alternating electrical signal through the patient's body, which is detected by electrodes in the stimulation module. In operation, a sensor module detects a blow to the sensed body member and sends a signal to the stimulation module which in turn generates a controlled electrical current for aversive stimulation.

摘要： An implantable automatic defibrillator includes sensors which are placed on or near the patient's heart to detect electrical signals indicative of the physiology of the heart. The signals are digitally converted and stored into a FIFO region of a RAM by operation of a direct memory access (DMA) controller. The DMA controller operates transparently with respect to the microprocessor which is part of the defibrillator. The implantable defibrillator includes a telemetry communications circuit for sending data outbound from the defibrillator to an external device (either a patient controller or a physician's console or other) and a receiver for sensing at least an externally generated patient ECG recording command signal. The patient recording command signal is generated by the hand held patient controller. Upon detection of the patient ECG recording command, DMA copies the contents of the FIFO into a specific region of the RAM.
