  • Patent number: 8519639
    Abstract: An improved, solar-controlled light device with a circuit-control having a phototransistor, a variable resistor, and a first transistor connected to a storage unit, to a solar cell, and to a current-control. The variable resistor can be set to permit the device to turn on at pre-set ambient light levels. The current-control has a transformer, a second resistor, and a second transistor, connected at one end of the current-control to a light and at another end connected to the circuit-control, wherein the current-control senses the amount of power and boosts the power as needed to a sufficient level to power the lights.

  • Patent number: 7656097
    Abstract: A control system for an HID lamp, which in one implementation includes a magnetic ballast control system for an HID lamp using Zigbee. A plurality of condensers or choke coils of different capacities is mounted on a magnetic ballast for the lamp, and an electronic switch unit controls illumination according to change of such capacities. RF transmitting/receiving means using a Zigbee-based frequency are employed to turn the HID on and off, and to control illumination through wireless remote communications, thereby achieving considerable energy savings. Operational states of the HID lamp and ballast can be bi-directionally controlled through the communication module, with failures of the HID lamp and ballast automatically detected and notified to users.

  • Patent number: 7531967
    Abstract: The invention provides a power supply or drive circuit for a pulsed flashlamp which utilizes a two-core component having common windings as both an inductor for arc mode drive and for breakdown triggering of the lamp. Discharge of a capacitor through the inductor and lamp is controlled by a high-speed semiconductor switch which is turned on and off by a suitable control, current flowing from the inductor through a one-way path including the lamp when the switch is off. The control maintains the ratio of the power variation through the lamp to the average power through the lamp substantially constant. The controls may also be utilized to control output pulse shape. Novel protective features are also provided for circuit components during turn on periods for the switch.

  • Patent number: 6788012
    Abstract: A simple and less expensive high voltage pulse generating circuit including a low voltage direct current voltage source having one output terminal connected to another output terminal via a series circuit of a first switch with a low withstand voltage, an inductance storing inductive energy and a second switch with a high withstand voltage, and a branch circuit including a free-wheel diode connected between the other output terminal of the direct current voltage source and a common connection point between the first switch and the inductance. After storing inductive energy in the inductance by turning “on” the first and second switches, these first and second switches are turn “off” to commutate the energy stored in the inductance into a capacitive load connected across the second switch to charge the load abruptly and generate a high voltage pulse having a very narrow width without using a complicated and expensive magnetic compression circuit.

  • Patent number: 5598438
    Abstract: For the demodulation of modulated carrier signals (AS) supplied to the cordless telecommunication apparatus, a data comparator (1212) is used in the cordless information transmission, especially a DECT-specific information transmission, which data comparator is supplied for this purpose with a reference signal (RS) generated by integration of the carrier signal (AS) at an input (E2) for the purpose of demodulating the carrier signal (AS). Since, according to the DECT transmission convention, two identical bit values of a synchronization word (S-BW) must also be detected in addition to the demodulation, a decision threshold (ES) of the reference signal (RS) is changed by an error value (dES). In the cordless telecommunication apparatus, a compensation arrangement (16, 19, 142) which compensates for this error value (dES) is therefore additionally provided.

  • Patent number: 5406177
    Abstract: In accordance with the invention, there is provided a ballast circuit for a gas discharge lamp. The circuit comprises means for providing a d.c. bus voltage on a bus conductor with respect to ground. The circuit includes a resonant load circuit incorporating a gas discharge lamp and including first and second resonant impedances whose values determine the operating frequency of the resonant load circuit. Further included is a converter circuit coupled to the resonant load circuit so as to impress a bidirectional voltage thereacross and thereby induce a bidirectional current in the resonant load circuit. The converter comprises first and second switches serially connected between the bus conductor and ground, and having a common node coupled to a first end of the resonant load circuit and through which the bidirectional load current flows. A current-sensing winding senses at least a portion of the current flowing in the resonant load circuit.
