  • Patent number: 9189724
    Abstract: The present invention provides a noncontact interface technique capable of performing communication operation without stopping an internal operation even when a clock signal cannot be extracted from a carrier wave. In a semiconductor device that receives a modulated carrier wave from an antenna, generates an internal clock signal on the basis of a clock signal extracted from the received carrier wave, and performs operation synchronously with the internal clock signal, a PLL circuit that receives the extracted clock signal and generates the internal clock signal is provided with a voltage control oscillation function. In the case where the clock signal extracted from the carrier wave is discretely interrupted, the function makes the internal clock signal maintained at a frequency immediately before the interruption. With the configuration, even when the clock signal extracted from the carrier wave is interrupted, internal data processes such as decoding and bus interfacing can be continued.

  • Patent number: 9028076
    Abstract: In a projector, a projection unit includes a projection mechanism that projects an image and an air hole that takes in or exhausts air used to dissipate heat generated from a light source included in the projection mechanism. A housing covers the air hole when the projection unit is in a storage position in which the projection unit does not project an image and uncovers the air hole when the projection unit is in a projection position in which the projection unit projects an image. The drive mechanism moves the projection unit or a cover member. An electronic control unit controls the drive mechanism to move the projection unit to the projection position in which an image is projected when receiving a predetermined projection preparation request and move the projection unit to the storage position in which no image is projected when receiving a predetermined storage request.

  • Patent number: 8050651
    Abstract: The detector is reduced in DC power consumption when an input signal is at a low amplitude level. The detector includes first and second input terminals, first and second transistors, and a load element. The first and second input terminals are supplied with complementary input signals reverse to each other in phase. The first input terminal is connected to the first input electrode of the first transistor and the second input electrode of the second transistor. The second input terminal is connected to the second input electrode of the first transistor and the first input electrode of the second transistor. The load element is connected between output electrodes of the transistors and an operating voltage point. A detection voltage resulting from full-wave rectification arises from a circuit node. In the condition where a signal input to the input terminals is at a low amplitude level, the transistors are both in OFF state. Thus, DC power consumption is reduced.
