A system for controlling multiple energy storage devices in an uninterruptible power supply (UPS) system is provided. In one embodiment of the invention, the system generally includes a charger coupled to a direct current (DC) bus of the UPS system, and two or more energy storage circuits, each of which includes a power regulator coupled to the charger and coupled to the DC bus, at least one energy storage device coupled to the power regulator, and a processor coupled to the power regulator for controlling the charge and discharge of the at least one energy storage device. In another embodiment of the invention, digital communication between two or more controllers is accomplished over the DC bus through use of the Control Area Network (CAN) protocol.

摘要:
A method of charging a NiMH or NiCd battery such that charging does not occupy a substantial amount of time and such that the operating temperature of the battery is reduced during the lifetime of the battery, thereby extending the life of the battery. This invention is a method of charging that is accomplished using a temperature differential method to continuously regulate the rate of charge injected into the battery. An amplifier is used to amplify the difference in temperature between one or more cases in which the battery is contained and ambient temperature. In this method, the greater the difference in temperature, the lower the charging current is injected into the battery. The method of charging may be incorporated into uninterruptible power supply equipment.

A method of fluid delivery from a rotary peristaltic pump is provided. It comprises providing a roller assembly having a plurality of rollers, the roller assembly having at least one anomalous range and determining a rotational position of the plurality of rollers. The method further comprises increasing a speed of the plurality of rollers when at least one of the plurality of rollers are in the anomalous range and decreasing the speed of the plurality of rollers when each of the plurality of rollers are outside the anomalous range.
摘要:
A system and method for preventing an undesirable reverse rotation of an infusion pump assembly. The infusion pump motor includes a roller assembly, a coil, a rotor, a rotor position sensor, and a controller. The rotor is in communication with the coil, and the rotor is rotationally coupled to a roller assembly. If the pump is in not pumping, then the system monitors for reverse rotation of the pump, and if reverse rotation of the pump is detected, energizes the coil in a manner that holds the rotor in place. The system may also activate an indicator if reverse rotation is detected.
