A circuit interrupter electrically connects a line terminal to a load terminal in a closed condition and electrically disconnects the line terminal from the load terminal in the open condition. A controller includes a fault detector configured to detect a fault in an electrical signal in a load circuit, such that when a fault is detected on the load circuit, the fault detector causes actuation of the interrupter to the open condition. The controller is adapted to receive an off command, and in response to the off command, generate a simulated fault in the load circuit, such that the fault detector causes actuation of the interrupter to the open condition, such that one and the same interrupter is employed for both fault tripping and commanded tripping.

An intelligent battery system for powering a mobile workstation includes a mounting block having a first battery interface bracket for the releasable attachment of a first battery, a second battery interface bracket for the releasable attachment of a second battery and a third battery interface bracket for the releasable attachment of a backup battery, and a power control circuit functionally integrated with the mounting block and being capable of detecting a change in status of at least one of the first and second batteries and routing the flow of electrical power from the first, second and backup batteries in dependence thereon.

Intelligent battery system

A light analysis system for analyzing light transmitted through an ampoule includes a housing having at least one receptacle for the ampoule, a cover for substantially preventing ambient light from affecting the receptacle and having an interior reflective surface, and a master control system. Each receptacle includes at least one light source and a photodetector positioned such that the light from the light source passes through the receptacle (and thereby the ampoule and its contents) prior to entering the photodetector. According to one preferred aspect of the invention, the receptacles are provided preferably at a 30&deg; to 45&deg; angle relative to vertical. According to another preferred aspect of the invention, the light source is at least one LED which is directed to transmit light upward into the reflective surface of the cover such that the light is reflected by the cover downward into the receptacle toward the photodetector. The master control system permits user input, operates the light analysis system, and provides a user-readable display for the output of the results of the light analysis of the contents of the ampoule in the receptacle. The apparatus may include a large number of receptacles suitable for laboratory use or may include fewer or one receptacle suitable for home or portable use. Power supply circuitry is provided facilitating the use of the apparatus in a variety of environments.

An ampoule incubator and light analyzer is provided which includes a housing having at least one receptacle for an ampoule, an incubation system, a light analysis system, and a master control system. According to the invention, the incubation system includes, for each receptacle, a heating element which heats the ampoule and a temperature sensor which senses the temperature of the ampoule. Each receptacle is preferably insulated to prevent unintended heating of neighboring receptacles of the apparatus. The incubation system is adapted to quickly heat the receptacle, and consequently the ampoule provided therein, up to the desired temperature. The incubation system is calibrated by soaking the circuits of the control system in a controlled temperature environment maintained at the desired operation temperature for analysis of the ampoules. When the circuits are at the desired operation temperature, the circuits of the incubation system are powered and switches in the circuits are closed causing a microcontroller of the master control system to store digital representations of the temperature of each individual receptacle in non-volatile memory. Then, during operation of the apparatus, the incubation system is directed to the values previously set in non-volatile memory during calibration, without necessitating expensive and error-prone trim pots, ultra high precision components, or other adjustable components.
