  • Patent number: 11678079
    Abstract: An object is to improve a frame rate in a solid-state imaging element that employs a global shutter method. In the solid-state imaging element, a photoelectric conversion element generates a charge by photoelectric conversion. A charge holding transistor holds the charge. A backward flow prevention transistor generates a potential barrier between the photoelectric conversion element and the charge holding transistor immediately after the charge is transferred from the photoelectric conversion element to the charge holding transistor. A floating diffusion layer accumulates the charge and generates a voltage corresponding to an amount of the charge. A transfer transistor transfers the charge from the charge holding transistor to the floating diffusion layer.

  • Publication number: 20230010270
    Abstract: The present invention detects a predictive abnormal phenomenon in a battery pack and prevents the use of the battery pack before power is shut off at a fuse. The battery pack comprises: a battery cell; a connection unit which is electrically connected to the battery cell and is connected to an external electrical apparatus main body; and a control unit which controls the battery cell, wherein, when detecting an abnormal state such as chattering, the control unit causes a charge prevention signal (LS) and a discharge prevention signal (LD) to be continuously output and makes the charge and discharge of the battery pack impossible (steps 226-228). The continuous output of these prevention signals is configured not to be negated by an operation of a user, and the battery pack can be made unusable by software control.
