Patent JP-2019165248-A (JP)
Title: Semiconductor device
Inventor: OUMARU TAKUO
IPC: H01L21/8242
Filed: 2019-06-06
Abstract: To provide a signal processing circuit which can reduce power consumption.SOLUTION: In a semiconductor device, during a period where power source voltage is not supplied to a storage element, data stored in a first storage circuit corresponding to a nonvolatile memory is retained by a first capacitative element provided in a second storage circuit. By using a transistor where a channel is formed in an oxide semiconductor layer, signals retained by the first capacitative element are kept over the long term. As a result, the storage element can retain storage contents (data) even during a period where supply of the power source voltage stops. In addition, since the signals retained by the first capacitative element is converted to a state (ON state or OFF state) of a second transistor and read from the second storage circuit, original signals can be precisely read out.SELECTED DRAWING: Figure 1

Title: System guiding speaker array and microphone array by using coded beam, method, and, program
Inventor: LIU QIONG
IPC: H04R1/40
Filed: 2019-06-26
Abstract: To provide a method of guiding a speaker array or a microphone array on the basis of a direction output of a small optical sensor attached to a viewer of a television, an operator under a noisy environment, or a user of an AR/VR system.SOLUTION: A light projector is arranged to a ceiling to transmit a sequential on/off signal which is different in each pixel. Two optical sensors are attached to each speaker array or each microphone array, and one or a plurality of optical sensors is attached to each user. Since each projector pixel is corresponded to a specific direction, the optical sensor specifics the direction corresponding to the projector when the optical sensor receives a sequential signal from the projector, and can report it to a central station. When a direction of a speaker/microphone array and a user direction are known, the system generates an optical phase shift for the different speaker signal, and can generate a sound with a directional pattern in each person. Simultaneously, the central station can determine the phase shift for combining the sound from the different microphone.SELECTED DRAWING: Figure 5
