    Abstract: A ground fault interruptor circuit interrupts the flow of current to a pair of lines extending between a source of power and a load. The ground fault interruptor circuit includes a circuit breaker comprising a normally open switch located in one or both of the lines, a relay circuit for selectively closing the normally open switch, an electronic latch circuit operable in first and second bi-stable states and a fault sensing circuit for sensing the presence of a fault condition in at least one of the lines. The electronic latch circuit causes the relay circuit to close the normally open switch and maintain the normally open switch in its closed position when the electronic latch circuit is in the first bi-stable state. The electronic latch circuit also causes the relay circuit to permit the normally open switch to return to its normally open condition when the latch circuit is in its second bi-stable state. A fault sensing circuit senses the presence of a fault condition in at least one of the lines and causes the electronic latch circuit to latch in its second state upon detection of the fault condition.

    Abstract: A monitor for detecting miswiring in standard 3-spade AC electrical outlets. The monitor includes a housing, prongs for insertion into the outlet to be tested, outlet ports for an external plug, and a banana jack for a wrist strap or other anti-static device. If the outlet is properly wired, a lamp will illuminate. If, however, the outlet is miswired, one of two silicon controlled rectifiers will shunt current around the lamp, extinguishing it, indicating to the user the presence of a faulty outlet. A junction field effect transistor is also provided to activate one of the silicon controlled rectifiers when one particular miswiring condition is present.

    Abstract: A resettable circuit interrupter in a ground fault detector circuit utilizes a housing which slideably retains a solenoid coil wound on a bobbin. A contact carrier is attached to the bobbin and one or more moveable contacts are provided on the carrier opposite a corresponding set of fixed contacts. A plunger slides through a central passageway in the solenoid coil. The bobbin is spring biased so that the contacts are in a normally open position. In a manually resettable version, when the solenoid coil conducts a predetermined current, manually activating the plunger causes the plunger to magnetically couple to a footplate attached to the bobbin. When a plunger spring returns the plunger to its original position, the bobbin and contact carrier move with it and the contacts are closed. When the solenoid coil conducts insufficient current to magnetically couple the plunger and footplate, the bias springs maintain the contacts in the normally open position. In an electrically resettable version the contacts may be reset by electromagnetic energy alone, without manual activation of the plunger.

    Abstract: Embodiments of a switched reluctance (SR) motor for use in a integrated vacuum system for a vehicle are disclosed. The SR motor may receive input voltage directly from an electrical storage device used to start up an engine of the vehicle. The SR motor may include an encoder that triggers an optical sensor to provide signals to a motor controller. The motor controller may energize stator poles based on the received signals. The encoder may be mechanically phase-advanced with respect to poles of the rotor to ensure proper start-up of the SR motor. Commutations of the motor may occur before a point of maximum inductance where the rotor and stator are aligned. In a preferred embodiment, the input voltage received by the SR motor is in a range of 9-16 Volts DC, a maximum drawn current is 36 amps, and the phase advance is between 9-11 degrees.

    Abstract: The disclosed vacuum cleaner system for an automobile fits in a cavity in the vehicle and has a tank that can be removed in a lateral direction without tools and without detaching the vacuum hose. A circuit board that carries an electronic controller is positioned alongside the motor and extends generally parallel to both the axis of the motor and the lateral direction in which the tank is removed. Cooling air is drawn though a cooling air inlet on the cabin wall to the circuit board, and then one side of the motor, through the center of the motor, to the cooling fan. From there, it is blown into a cavity where it joins exhausted working air from the vacuum and is exhausted from the vehicle through an air release opening that leads to the exterior of the vehicle.
