| 20090102390 | CIRCUIT ARRANGEMENT FOR OPERATING A HIGH PRESSURE DISCHARGE LAMP - A circuit arrangement for operating a high pressure discharge lamp includes a voltage transformer, a load circuit which is supplied by the voltage transformer and provided with connections for the high pressure discharge lamp (La), a choke (L | 04-23-2009 |
| 20100289414 | TWO-STAGE BALANCER FOR MULTI-LAMP BACKLIGHT - A two-stage balancer for a multi-lamp backlight is electrically connected to a driving unit through a driving transformer. The two-stage balancer includes a plurality of first balancing transformers, second balancing transformers, and lighting units. Each of the first balancing transformers is electrically connected to the corresponding second balancing transformers to form a two-stage structure. In addition, a primary winding and a secondary winding of the second balancing transformer is electrically connected in series to one lighting unit, respectively, to form a circuit loop. Further, each of the circuit loops is electrically connected in parallel. Whereby the two-stage balancer provides much better current balance between the parallel circuit loops, and outputs a sinusoid-like driving current to increase lighting efficacy and further maintain uniform brightness of the multi-lamp backlight. | 11-18-2010 |

PLURAL CONTROL STATIONS | 2 |
| 20090072766 | Multi-way sensor switch - A system for controlling a load circuit is disclosed. The system includes a plurality of multi-way sensor switches for mounting in an electrical boxes and coupling to the load circuit. Preferably, each of the multi-way sensor switches includes a tactile switch for manually opening and closing the load circuit load circuit, a built-in sensor for automatically opening and closing the load circuit in response to a level of detected motion and a micro-processor for generating status signals. The status signals are transmitted between each of the multi-way sensor switches over a traveler wire that is electrically coupled to each of the multi-way sensor switches. The micro-processor then uses the status signals to synchronize the operation of each of the multi-way sensor switches to allowing the multi-way sensor switches to operate in a true three-way fashion. | 03-19-2009 |
| 20100052576 | RADIO-FREQUENCY LIGHTING CONTROL SYSTEM WITH OCCUPANCY SENSING - A load control system controls an electrical load provided in a space and comprises a load control device and one or more occupancy sensors. The load control device controls the load in response to the wireless control signals received from the occupancy sensors. Each occupancy sensor transmits an occupied control signal to the load control device in response to detecting an occupancy condition in the space and a vacant control signal to the load control device in response to detecting a vacancy condition. The load control device turns on the load in response to receiving the occupied control signal from at least one of the occupancy sensors, and turns off the load in response to receiving vacant control signals from both of the occupancy sensors. The load control device is operable to determine that no wireless control signals have been received from the occupancy sensors for the length of a predetermined timeout period and to subsequently turn off the load. | 03-04-2010 |

| 20130181618 | Organic Electroluminescent Display Device - The present invention overcomes image defects such as the brightness inclination or smears by reducing the line resistance of a power source bus line which supplies electricity to organic EL elements. A plurality of pixels which are arranged in a matrix array is connected to power source lines, and the plurality of power source lines are connected to a power source bus line. Both ends of the power source bus line are connected to a power source part via a FPC. By supplying electricity to both ends of the power source bus line from the power source part, the line resistance of the power source bus line can be reduced. | 07-18-2013 |

PULSE STORING SYSTEMS OF THE GASEOUS DISCHARGE-TUBE TYPE | 1 |
| 20110254447 | Discharge lamp lighting apparatus - A discharge lamp lighting apparatus includes a capacitor, a charge circuit for charging the capacitor, a switching element, a gate driving circuit that controls ON and OFF states of the switching element, a simmer current supply circuit for passing simmer current through a discharge lamp, a starting circuit that impresses high voltage to a starting electrode, and an electric discharge sequence control circuit that generates the gate signal and the starting signal. When lighting the discharge lamp, a sequence of the gate signal corresponding to an alternating repetition of the ON and OFF states of the switching element is generated. Before outputting the starting signal, the switching element is ON as a stand-by state. Then the sequence starts when the starting signal is outputted. | 10-20-2011 |
