Abstract: An integrated circuit with analog device fault detection includes an integrated circuit die having an analog device, an on-line fault detector and a control circuit. The analog device has a power input, an analog device input and an analog device output and the on-line fault detector is coupled to at least one of the power input, the analog device input and the analog device output and has a fault detector output. The control circuit is coupled to the fault detector and responsive to the fault detector output. Detector self-test (DST) circuitry can be provided to test the on-line fault detector and one or more circuit breakers can be provided to protect the analog device and other devices attached to the analog device.

Abstract: The present invention utilizes a torque compensation system and a power control feedback system to reduce power consumption in a linear peristaltic pump. The linear peristaltic infusion pump includes an electric motor, which is connected to a cam shaft with multiple cams positioned thereon. Numerous elongate fingers cooperate with the cams to partly occlude an intravenous drip tube at multiple points along the tube's path. A torque compensation system and power feedback control system reduce the overall power consumption of the pump. A torque compensation cam positioned on the cam shaft, in combination with a torque compensation cam follower and a mechanical spring assist the motor while it is working against a rising cam follower. The power feedback control system comprises a controller which optimally adjusts the power supplied to the drive means so as to reduce overall power consumption of the pump.
