  • Patent number: 11967510
    Abstract: A heating circuit is provided. The heating circuit is disposed in a chip which has a normal operation temperature range. The heating circuit includes a comparison circuit and a thermal-energy generation circuit. The comparison circuit compares a temperature voltage with a first threshold voltage. The temperature voltage represents a temperature of the chip. The thermal-energy generation circuit is controlled by the comparison circuit. When the temperature voltage is less than the first threshold voltage, the comparison circuit enables the thermal-energy generation circuit to generate thermal energy to raise the temperature of the chip.

  • Patent number: 11940610
    Abstract: An autofocus system includes a focus light source, an objective lens, a defocus lens, a first image sensor, and a controller. The defocus lens is disposed on the transmission path of the focus light beam, so that a minimum light point of the focus light beam passing through the objective lens deviates from a focus of the objective lens. The first image sensor is configured to receive a focus reflected light beam generated after the focus light beam is reflected by the sample. The controller is electrically connected to the first image sensor. According to a center change of gravity, a position change, or an energy change of a light spot formed by the focus reflected light beam on an image plane of the first image sensor, the controller drives the objective lens or the sample to move, so that the focus of the objective lens falls on the sample.

  • Publication number: 20240069583
    Abstract: A control circuit including a storage circuit, a voltage detection circuit, a processing circuit, and a wake-up circuit is provided. The storage circuit includes a register and stores a program code. The voltage detection circuit detects an external voltage. The processing circuit accesses the register in response to the external voltage reaching a first predetermined voltage. The processing circuit enters a power-down mode in response to the external voltage reaching a second predetermined voltage. In the power-down mode, the processing circuit stops accessing the register. The wake-up circuit determines whether a wake-up event occurs. In response to the wake-up event, the wake-up circuit directs the processing circuit to exit the power-down mode and enter an operation mode. In response to there being no wake-up event, the processing circuit stays in the power-down mode. In the operation mode, the processing circuit executes the program code.
