  • Patent number: 8669917
    Abstract: Here are described apparatus and methods for construction and operation of transmitters and receivers for sending and receiving signals. The signals are often low velocity and matter penetrating. The application describes a method of sending information by means of applying electrical signals to salt solution filled wood or other plant matrices. Receivers and transmitters utilize similar along the grain (as in the direction of a tree trunk) matrices. Trees or other plants with ordinary sap also are receivers and possible transmitters with the proper manipulation. Perhaps the chief advantages of the described transmitters and receivers are the matter penetrating qualities of the signals involved. These permit transmission of information through space, matter, and even mountains as found by the inventor.

  • Patent number: 8669929
    Abstract: Disclosed is a gate printed circuit board, a connector-free liquid crystal display (LCD) panel assembly, a driving-signal timing module included in the liquid crystal display (LCD) panel assembly, and a method of driving the liquid crystal display (LCD) panel assembly. According to the present invention, since a separate connector and a gate printed circuit board of a conventional LCD panel is not required for applying a gate-driving signal generated from an external information processing device, a thickness and the number of parts of the LCD device is reduced. Further, when the gate-driving signal is transmitted through the TFT substrate, the voltage Voff for maintaining a thin-film transistor (TFT) in a turned-off state is modified so that users may not recognize the imbalance in brightness.

  • Patent number: 8669933
    Abstract: A liquid crystal display according to an embodiment of the present invention includes a liquid crystal display panel, an illumination unit for the liquid crystal display panel, a plurality of photodetectors, and a control unit Cnt to control the brightness of the illumination unit. The photodetectors are TFT ambient light photosensors LS1 to LS3, for example, which produce outputs that require time to reach a predetermined value, which the time is correlated with the intensity of ambient light. Detection circuits coupled to the photodetectors include circuits (Cmp1 to Cmp3) logically inverted when an output from the TFT ambient light photosensors LS1 to LS3 reaches a predetermined value. The control unit Cnt includes a discrimination implement Maj that determines that the intensity of ambient light has changed when outputs from the majority of the detection circuits are logically inverted.

  • Patent number: 8669934
    Abstract: A driving circuit is provided, which is configured to supply a driving voltage and a driving current to an LED string. A first detection resistor is arranged on a path of the LED string. A voltage source outputs a control voltage having a level that corresponds to the target luminance level of the LED string, and a first threshold voltage that is proportional to the control voltage. A controller generates a gate pulse signal having a duty ratio that is adjusted such that the voltage drop across the first detection resistor matches the control voltage. A first driver drives a switching transistor of a DC/DC converter according to the gate pulse signal. When the voltage drop across the first detection resistor exceeds the first threshold voltage, a first comparator stops the switching operation of the switching transistor.
