  • Patent number: 12109907
    Abstract: A power supply system charging a battery of an electric car through a grid power line and supplying electric power stored in the battery to electrical equipment through an in-home wiring, including: an isolated converter connected to the grid power line, the in-home wiring and the battery; and a controller controlling the isolated converter. The isolated converter includes a plurality of isolated converter circuits each including two full-bridge circuits. One of the plurality of isolated converter circuits further includes two booster circuits. The controller receives load amount information depending on the operation state of the electrical equipment from a monitor device and switches, on the basis of the load amount information, an operating mode of the isolated converter to one of first mode to fourth mode. The controller causes the two booster circuits to perform a boosting operation in the first mode and third mode.

  • Patent number: 12104893
    Abstract: A three-dimensional measurement device measures the three-dimensional shape of an object or information indicating a shape thereof based on event data. A stripe pattern is projected from the projection unit to the object. The object is optically imaged by an imaging unit and an image based on event data is acquired. The event data, which are outputted from the image sensor, include two-dimensional point data that specifies the positions of pixels corresponding to the pixels that had luminance changes responsively to the stripe pattern projected. Based on the event data, an image of the object is obtained. The image sensor outputs positive luminance change event data when brightening luminance changes and negative luminance change event data when darkening luminance changes. The measurement unit obtains luminance information based on a time difference between output of event data of positive luminance changes and output of event data of negative luminance changes.

  • Publication number: 20240310165
    Abstract: A projection unit projects predetermined stripe pattern to measurement object so that emission start timing differs for each stripe number. Imaging unit is equipped with imaging device that outputs event data including two-dimensional point data in which position of pixel is specified corresponding to pixel whose brightness has changed when received. An imaged image is generated from event data output from imaging device. The imaging device outputs event data of positive brightness change in case of the brightness change to brighten and event data of negative brightness change in a case of brightness change to darken. The measuring unit obtains stripe pattern information based on time difference between output of event data of the positive brightness change and output of the event data of the negative brightness change on pixel-by-pixel basis in captured image and stripe number specified from output timing of the first event data constituting this time difference.

  • Patent number: 12064885
    Abstract: A robot hand controller is provided for controlling operations of a robot (e.g., an industrial robot), which is configured to be held with a position and posture of an arm being changed by a user, and a hand mounted on the arm and held with an open/closed position being changed by a user. In the controller, the position and posture of the arm and the open/closed position of the hand are detected. A gripping force of the hand is detected. A reception unit receives an operation of recording a state of the arm and the hand, and a recording unit records, as state information in time series, the position and the posture, the open/closed position, and the gripping force, which are detected when the operation is received by the reception unit. Operations of the arm and the hand are controlled to reproduce the recorded state information recorded in time series.

  • Patent number: 12026976
    Abstract: An authentication system, wherein an RF tag stores a first facial feature point extracted from a captured image of a user's face. In an authentication device, a wireless communication unit wirelessly reads and writes information from and to the RF tag. A controller adjusts wireless communication conditions of the wireless communication unit, and estimates a position of the RF tag according to a distance to the RF tag. The controller adjusts imaging conditions of an imaging unit. A position of the user is detected according to an imaging resulting from the imaging unit. A second facial feature point is extracted from an image of the user's face captured by the imaging unit, and is collated with the first facial feature point read from the RF tag. Based on a collation result, authentication of the user is performed.

  • Patent number: 12019722
    Abstract: A user authentication system uses an information code such as a two-dimensional information code. The authentication system includes an authentication device, and the user is authenticated by combining the authentication device with a user's mobile terminal. In the mobile terminal, an authentication code in which facial feature points extracted from user's facial images are recorded is stored in the memory. In the authentication device, facial feature points are extracted from images of a human's face captured by an imaging unit, after being determined to be in a facial recognizable state, and the authentication code is displayed on the screen of the mobile terminal. The e facial feature points recorded in the authentication code are read from the captured images of the authentication code. The extracted facial feature points and the read facial feature points are subject to matching with each other in order to authenticate the user.

  • Publication number: 20240176970
    Abstract: In an information reader, a first relationship information, which defines the two-dimensional area of a first information code (e.g., the position coordinates of the four corner points), is detected from a first information code image. The first information code is subjected to reading information, based on the detected first relationship information. Parameters of a learning model are then adjusted based on training data including multiple successful cases of a reading process using the first relationship information. A second information code image captured by a camera is inputted to the learning model. A second relationship information, which is an estimated value of the information that defines the two-dimensional region of the second information code, is obtained from the learning model. The information recorded in the second information code is read based on the acquired second relationship information, thus reading results being outputted.
