Abstract: There is provided a second switch used to turn on/off connection between a first circuit portion with a decoupling capacitance on a first switch side. Then, in accordance with on/off of the first switch, the second switch is turned on/off. By performing such switch control, when the first and second switches and are turned off and the first circuit portion shifts to the standby mode, the electric charge stored in the decoupling capacitance in the on state of the first and second switches is held. The electric charge held in the decoupling capacitance contributes to charging of a parasitic capacitance of the first circuit portion when the first and second switches and are again turned on. Therefore, when the first circuit portion shifts from the standby mode to the normal operating mode, the instantaneous voltage drop at a first connection point can be reduced.

Abstract: Grip actuated control system to provide operational control of vehicle functions at a gripping surface of handlebar equipped vehicles. The system can be provided as original equipment and as an aftermarket addition or replacement for existent vehicle controls. The system includes one or more grip controls positioned adjacent a user's fingertips in a grip or glove assembly which are in communication with a control module. The control module is connected to existent or provided vehicle wiring and thus to respective operational equipment such that user actuation of a grip control induces the control module to provide a corresponding output to activate/deactivate or regulate the operation of the respective vehicle equipment. Communication between the grip controls and control module can be wireless for increased flexibility in installation and placement of the module on the vehicle. Combinations, sequences, and relative timing of the grip controls can provide numerous distinct control functions.

Abstract: An apparatus and method are provided for a security device for residential and/or commercial use. A first magnetic member has a first magnet with a north and south pole, and a second magnetic member has a second magnet with a south and north pole. Contact between the north pole of the first magnet and south pole of the second magnet, or vice versa, completes an electrical circuit by conducting electricity between the first and second magnets, and a magnetic force between the first and second magnets holds the first and second magnets in contact. The electrical circuit is broken when a force sufficient to overcome the magnetic force is applied to separate the first and second magnets. When contact between the first magnet and second magnet is broken off, such as by opening a door or window, the electrical circuit is broken, and an alarm is triggered.

The sheet member includes a member having a light reflection region and an electret member that is charged at a predetermined electric potential.

Abstract: A bi-directional smooth transition switch with bumpless transfer is disclosed. It is composed of two feedback loops, each with feedback and forward-loop compensators. During loop operation, one feedback loop is active, while the other is inactive. The smooth transition switch operates in the following manner. The switch output is measured. Next, an error signal is formed as the difference between the forward-loop compensator output and the switch output, which is fed to the input of a high gain feedback compensator. The output of the feedback compensator is a feedback signal. When no switching occurs, the feedback signal remains zero in the active loop, and the output signal of the inactive loop will track the output signal of the active loop. When the switchover occurs, the inactive loop will replace the original active loop and provide smooth transition switch's output.

Abstract: A dual solid state switch architecture has a plurality of control/monitor ports, selected ones of which are used to control the operation of a pair of power MOSFETs current flow paths through which are coupled to prescribed ones of a plurality of input/output ports that are adapted to be coupled to a circuit path containing a load and either and AC or DC power source therefor.
