Abstract: A shaft seal pressure compensation system for an underwater device such a remotely operated vehicle powered by motor driven thrusters where the shaft of the motor extends from a motor housing into the surrounding water and is sealed by a shaft seal by automatically supplying air to pressurize the thrusters to balance the internal pressure of the thrusters to match the ambient water pressure. The air is supplied by a variable volume container that responsive to a pressure differential between the external ambient pressure and an internal pressure within the variable volume gas container for adjusting the volume of the variable volume gas container so that the internal pressure equals the ambient pressure, and thus balancing the system.

Abstract: A system includes a remote controller and an infusion pump. The infusion pump includes an RF telemetry portion configured to receive an RF data signal from the remote controller. A processing portion is configured to process the RF data signal received by the RF telemetry portion. A dispensing apparatus, responsive to the processing portion of the medical device, dispenses medicament in accordance with the RF data signal. The dispensing apparatus includes a fill sensor for providing an initialization signal to the processing portion of the medical device upon the dispensing apparatus being filled with at least a defined volume of medicament.

Abstract: A system for delivering a fluid to a patient includes a remote controller and an infusion pump. The infusion pump includes a dispenser for dispensing the fluid. An RF telemetry portion is configured to receive an RF data signal from the remote controller. A main processing portion is configured to process the RF data signal received by the RF telemetry portion, and control the dispenser in accordance with the RF data signal received by the RF telemetry portion. An interlock processing portion is configured to process the RF data signal received by the RF telemetry portion, and control the dispenser in accordance with the RF data signal received by the RF telemetry portion. The RF telemetry portion and at least one of the processing portions are incorporated into a single microchip.

Abstract: A system for delivering a fluid to a patient includes a remote controller and an infusion pump. The infusion pump includes a dispenser for dispensing the fluid. An RF telemetry portion is configured to receive an RF data signal, from the remote controller, that is broadcast in a non-restricted frequency band. A processing portion is configured to process the RF data signal received by the RF telemetry portion, and control the dispenser in accordance with the RF data signal received by the RF telemetry portion.

Abstract: A system for delivering a fluid to a patient includes a remote controller and an infusion pump. The infusion pump includes a dispenser for dispensing the fluid. An operationally-independent RF telemetry portion is configured to receive an RF data signal from the remote controller. An operationally-independent processing portion is configured to process the RF data signal received by the operationally-independent RF telemetry portion, and control the dispenser in accordance with the RF data signal received by the operationally-independent RF telemetry portion.
