Abstract: An electrical energy storage device for storing electrical energy and supplying the electrical energy to a driving motor at different power levels is disclosed. The electrical storage device has an energy battery connected to a power battery. The energy battery has a higher energy density than the power battery. However, the power battery can provide electrical power to the electrical motor at different power rates, thereby ensuring that the motor has sufficient power and current when needed. The power battery can be recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and both batteries can provide electrical energy at the different power rates as required by the motor. The energy storage device can be releasably connected to an external power source in order to recharge both batteries. Both batteries can be recharged independently to optimize the recharging and lifetime characteristics of the batteries.

Abstract: An ultra-high-efficiency switching power supply system integrating, into a single package, power conversion switches for multiple power supplies, an input power switching block, an output power switching block, control logic for controlling the power conversion switches and control input/output ports. This integrated multiple power supply package is called a Power Bridge and preferably implements the integrated components as one or more integrated circuit chips housed in the package housing. The Power Bridge is a bridge between the microprocessor of a portable computer and its internal and external power sources. The power supply system facilitates board design because the ultra-high-efficiency power module generally requires less space and generates less heat than conventional power supply circuitry. The power supply module improves power management because of improved communications connections between the power supply module control circuitry and other components, such as busses, other bridge modules and embedded controllers.

Abstract: A ceramic heating rate regulator for electrically powered thermal treatment operations is described. The regulator is made of a ceramic mixture containing molybdenum disilicide, which is an electrically conductive substance undergoing crystal structure transformation above 700.degree. C. The regulator comprises an elongated ceramic rod containing high concentration of molybdenum disilicide, the rod is subsequently insulated by a ceramic cylinder which contains silicon nitride and low concentrations of molybdenum disilicide. The regulator when incorporated in the heating circuit of the thermal treatment furnace will itself heat up and thus reduce the size of the heating current flowing in the circuit, as soon as the temperature of the regulator has reached the transformation temperature of molybdenum disilicide. The heating rate regulator is designed to be used in conjunction with conventional temperature controlling devices.

Abstract: The terminals of a thin plate rechargeable lithium battery are coated with a heat-sealable polymer. The coating forms a band on each face of the terminals and the band is heat-sealed to the inner insulator layers of a multi-layered polymer laminate enclosing the thin plate rechargeable lithium battery at a location close to an open edge of the insulator layer. Small sheets of rigid, high melting point, polymeric materials are inserted between the bands of coating carried by the terminals and the edge of the multi-layered laminate enclosing the lithium battery. A portion of the sheets of polymeric material is adhesively attached to the face of the terminal adjacent the bands of coating. The open edges of the multi-layered polymer laminate enclosure are subsequently sealed to enclose completely the thin plate lithium battery.
