  • Patent number: 10032102
    Abstract: Excess radio-frequency (RF) power storage in RF identification (RFID) tags, and related systems and methods are disclosed. The RFID tag is configured to operate with RF power received in wireless RF signals from a RFID tag antenna if received RF power meets or exceeds an operational threshold power for the RFID tag. The RFID tag is also configured to store excess energy derived from excess received RF power in an energy storage device if the received RF power exceeds the operational threshold power for the RFID tag. Thus, when RF power received by the RFID tag is not sufficient for operation, the RFID tag can operate from power provided by previously stored excess energy in the energy storage device.

  • Patent number: 8462287
    Abstract: An active matrix substrate capable of suppressing a change in an off characteristic of the TFT even when current passage time becomes longer is provided. A diode is connected between a video signal line and a conductive plate formed so as to cover a TFT of a pixel formation portion. Current is passed to the diode when a potential of a video signal applied to the video signal line is lower than that of the conductive plate, and the potential of the conductive plate becomes equal to that of the video signal line. No current flows when the potential of the video signal is higher than that of the conductive plate and the potential of the diode remains the same. Consequently, a leak current which flows from the pixel electrode of the pixel formation portion to the video signal line when the TFT is in the off state is suppressed.

The fluorescent tube illuminates the display through a first range of brightness above a predetermined transition level and the LEDs illuminate the display through a second range of brightness below the transition level. When the illumination of the display is adjusted through the transition level to account for changes in ambient light, the LEDs and the fluorescent tube are operated together, so that the combined brightness of the illumination provided by the LEDs and the fluorescent tube will provide the desired display brightness; this advantageously compensates for delayed illumination of the fluorescent tube at start up and for persistence in the tube after shutdown.
