  • Publication number: 20240126472
    Abstract: A semiconductor device includes a logic circuit, a memory, and a storage device. The storage device has a first special information storage region into which special information is written before a solder reflow process, a second special information storage region into which special information for updating is written after the solder reflow process, and a data storage region. The first special information storage region is constituted by a memory cell having a high reflow resistance and in which data is retained even after the solder reflow process. The second special information storage region and the data storage region are constituted by memory cells having a low reflow resistance and in which data may not be retained during the solder reflow process.

  • Publication number: 20240102917
    Abstract: According to an aspect, a detection device includes: photodiodes that are provided on a substrate; light-emitting elements that are arranged so as to face the photodiodes; and a light-transmitting placement substrate that is disposed between the photodiodes and the light-emitting elements and on which target objects are to be placed. The photodiodes, the placement substrate, and the light-emitting elements are arranged in the order as listed, in a direction orthogonal to the substrate. A light-emitting element of the light-emitting elements corresponding to the photodiode to be detected is controlled to be lit, and another light-emitting element of the light-emitting elements corresponding to the photodiode not to be detected is controlled to be unlit. The photodiodes to be detected output sensor values based on light from the lit-up light-emitting elements. The light-emitting elements adjacent to the lit-up light-emitting elements at least in row and column directions are controlled to be unlit.

  • Patent number: 11906588
    Abstract: A battery monitoring apparatus includes a battery ECU, satellite devices each of which measures the voltage at a battery cell in response to a command signal from the battery ECU, and a wireless module which achieves a wireless communication between the battery ECU and each of the satellite devices after a wireless connection between the battery ECU and each of the satellite devices is completed. When receiving a start signal outputted before a start switch for a drive power source of the vehicle is turned on, the wireless module is activated to start the wireless connection between the battery ECU and each of the satellite devices. This establishes and completes the wireless connections faster than when the wireless module is activated simultaneously with turning on of the start switch for the drive power source. This achieves quick monitoring of the state of the battery cells.
