  • Patent number: 10931098
    Abstract: An energy supply device for reliably supplying energy to electrical loads, provides the energy supply by constant voltage sources. The number of constant voltage sources corresponds to the number of electrical loads. The energy supply device has a deactivatable balancing network. In this case, only the compensating currents are conducted via the balancing network, while the energy supply is provided via a direct electrical connection between the constant voltage source and the load. If a fault occurs, the balancing network can be deactivated. Faults in one branch thus do not affect the level of reliability of the energy supply in the remaining branches. After a faulty component has been located and isolated, the sources that are still intact, and the intact loads, can be brought back into operation by suitably configuring the balancing network. The availability of the drive system can thus be increased.

  • Patent number: 7732945
    Abstract: Disclosed is a rectifier circuit that realizes a low threshold voltage without using a process step to enable reduction in cost and in variation of devices. An NMOS transistor has a threshold voltage. In the transistor, a voltage to be rectified is inputted to a second node, and a rectified voltage is outputted to a first node. A threshold voltage generator is connected to a gate of the transistor and the first node. The generator generates a voltage and outputs it to the gate of the transistor. The voltage is a voltage which is elevated by the threshold voltage with respect to a voltage of the first node and is decreased by a microvoltage sufficiently small with respect to the threshold voltage. Thus, when the voltage of the second node is decreased by the microvoltage or more with respect to that of the first node, the transistor is turned on.

  • Patent number: 6084384
    Abstract: A compact power supply circuit which can supply power to various apparatuses and circuits with a high degree of stability. A primary constant voltage circuit is connected to a second power supply line, which is supplied with power from a battery only when a relay is closed. The circuit supplies power to a third power supply line at a constant primary voltage. An auxiliary constant voltage circuit is connected to a first power supply line, which is always supplied with power from the battery for supplying power to the third power supply line at a constant auxiliary voltage lower than the primary voltage. A halt control circuit enables the operation of the auxiliary constant voltage circuit if power is supplied to the second power supply line and disables the operation of the auxiliary constant voltage circuit if the supply of power is interrupted for a period equal to or longer than a predetermined allowable time.

  • Patent number: 6066899
    Abstract: A battery drain limitation circuit for use in engine powered vehicles and equipment which rely upon a battery to start the engine and also to operate accessories. When the engine is not running, the circuit disconnects the battery from all loads when battery charge, as measured by either one of two complementary means responsive to high and low drain rates, respectively, falls to a level below which the battery charge may not be sufficient to start the engine. High drain rates exaggerate battery voltage reduction below no load voltage levels, and are detected by a low cutoff voltage level after which the battery voltage recovers to reflect sufficient charge to start the engine. Battery dissipation from low drain rates is prevented by a long timing delay following detection of a high cutoff voltage level. The circuit is rendered inoperable if the engine is running, by means of a microphone which detects engine noise. The device is simple to install at the battery.

  • Patent number: 6037748
    Abstract: A battery powered electronic system (50, FIG. 1) is controlled by a movement sensor (20) which senses the acceleration of the electronic system (50). The output of the movement sensor (20) is filtered by an event duration filter (FIG. 2, 120, 121) which determines if the output is of sufficient duration and acceleration to trigger a change in the operation of the electronic system (50). If the acceleration meets the triggering criteria, the electronic system (50) can be made to change an on/off state, an operating mode, or to effect an incremental change in the electronic system (50) such as adjusting the volume or channel setting. Additional movement sensors (20) oriented in different axes can be used to trigger a change in the operation of the electronic system (50) according to a plurality of different directions of acceleration.

  • Patent number: 6037676
    Abstract: A electrical current measuring and circuit breaking system attached between a vehicle battery and a vehicle power cable for measuring a current flowing from the battery. The electrical current measuring and circuit breaking system includes a clamp for connecting with a terminal of the battery and an electrical terminal for connection to the power cable. A device for sensing current flowing from the battery is connected to the clamp. The sensed current is transmitted to a comparator for comparing the sensed current to a reference value and determining when the sensed current is one of equal to and less than the reference value. The electrical current measuring and circuit breaking system may also include a device for alerting the operator when the battery power has reached a predetermined level. In this instance a signal will be transmitted to an alarm device available to the operator to alert the driver that the battery current is at a low level.

  • Patent number: 5982050
    Abstract: A Zener diode 16 is connected to each of single cells 10 of an electric double layer capacitor in parallel, and a resistor 18 is connected to each of the Zener diode 16 in series. Thus, in a case where a single cell 10 is excessively charged, when the bias voltage of the single cell 10 is equal to or higher than the Zener voltage, a discharge current flows through the Zener diode 16 connected to the single cell 10, so that the voltage decreases to the Zener voltage. Thus, it is possible to prevent the electric double layer capacitor from being excessively charged due to the dispersions in electrostatic capacity and internal resistance, and to stably accumulate electricity for a long time.

    Abstract: An antitheft system for use in portable consumer electronic equipment. The antitheft system includes an antitheft receiver that receives a deactivation code that is transmitted by a paging system transmitted when the device is reported stolen. Upon receipt of the deactivation code, a microprocessor within the electronic equipment causes the equipment to become inoperative. To ensure the antitheft receiver is not removed or tampered with, the microprocessor queries the antitheft receiver for a unique identification number associated with the device.
