  • Publication number: 20250030949
    Abstract: A visible light communication method transmits a signal by visible light communication. The visible light communication method includes modulating the signal into a predetermined blinking pattern, and transmitting the signal by causing visible light to blink according to the predetermined blinking pattern and toward a wall, from a projector disposed in an indoor space surrounded by the wall. The visible light communication method also includes projecting video from the projector toward the wall, wherein the visible light is reflected by the wall to prevent the signal from being received outside of the indoor space, and the signal is used to transmit data related to the video projected to a terminal in the indoor space.

  • Publication number: 20250021106
    Abstract: A moving object control apparatus in the present disclosure that adjusts a stop position of a moving object based on an instruction of a user, acquires instruction information of the user and acquires a captured image captured in a moving object. The apparatus determines a stop position of the moving object and controls traveling of the moving object to cause the moving object to travel toward the determined stop position. The apparatus (i) determines a first stop position using position information of a communication device used by the user or position information corresponding to a destination included in first instruction information of the user, and (ii) determines a second stop position based on second instruction information of the user and a region of a predetermined target identified in the captured image.

  • Publication number: 20250022498
    Abstract: A first circuit outputs first information indicating presence/absence of a magnetic wall between two adjacent portions among portions of a magnetic body, and second information based on the combination of magnetization states of the two portions. A first storage circuit stores first bits corresponding to the portions. A most significant bit of the first bits has a value independent of a magnetization state of a corresponding one of the portions, and the first bits have a value based on the first information. A second storage circuit stores the second information. The second circuit causes the first storage circuit to output the first bits when a value of a least significant bit of the first bits matches a value of the second information, and otherwise third bits having inverse values of the first bits.

  • Publication number: 20230420067
    Abstract: A memory system includes a nonvolatile memory including memory cells each configured to store first and second bits, and a memory controller. The memory controller is configured to: read first data by using a first voltage to a first read process that reads data corresponding to the first bit from the memory cells; read second data by using a second voltage to a second read process that reads data corresponding to the second bit from the memory cells; in a case where an error correction process of the first data is successful, determine a third voltage, based on the first data and third data that is obtained by error-correcting the first data; and update a first read voltage that is used to the first read process, from the first voltage to the third voltage.

  • Patent number: 11731256
    Abstract: Provided is an electric tool with which work efficiency can be improved. A controller of an electric tool can execute: a first control, whereby during a non-operating state after a motor has started up and before a tip tool is set to be in an operating state, the motor is driven at a slow idling rotation speed, and when the tip tool is set to be in the operating state, the motor is driven at a normal rotation speed which is higher than the slow idling rotation speed; and a second control, whereby in a case where a trigger switch has been turned off in a state where the motor is being driven at the normal rotation speed and the trigger switch is thereafter turned on again under a prescribed condition, the motor is driven at the normal rotation speed regardless of the state of the tip tool.
