  • Publication number: 20240114239
    Abstract: A system for remotely controlling microscopic machinery and a method thereof are provided. The system includes at least one local device and a remote host for sending a control command thereto. A microslide is placed on a microscopic camera device in the local device, and the microscopic camera device captures an image of the microslide according to a capture command in the control command. The local device transmits the image to the remote host in a video format. A motorized stage moves to a next preset position according to a movement command in the control command to capture another image of the microslide. The steps of capturing and transmitting the image and the step of moving are repeated until the microslide is captured completely. The invention can solve the problem of time delay when the image captured by the remote control microscopic camera device is displayed.

  • Publication number: 20230417805
    Abstract: A current sensing module includes a shunt resistor for receiving and sensing a current, a digital sensing circuit, and an analog sensing circuit. The shunt resistor includes a connecting part, a first resistive part and a second resistive part coupled in series to the first resistive part via the connecting part. The digital sensing circuit is coupled to the first resistive part for measuring a first analog voltage of the first resistive part when the current flows through the first resistive part, and providing a first digital measuring value associated with the first analog voltage. The analog sensing circuit is coupled to the second resistive part for measuring a second analog voltage of the second resistive part when the current flows through the second resistive part, and providing a second analog measuring value associated with the second analog voltage.

  • Patent number: 11415601
    Abstract: A resistor having low temperature coefficient of resistance includes a resistive part and two conductive parts connected to opposite sides of the resistive part. One conductive part has a through slot and a sensing portion between the through slot and the resistive part. The through slot has two inter-connected sections. Each section extends and ends with a closed end and has a parallel component, parallel to a main current direction defined on the resistor, and a perpendicular component, perpendicular to the main current direction. Another resistor having low temperature coefficient of resistance includes a resistive part and two conductive parts connected to two sides of the resistive part respectively. Each conductive part has a protrusion block, extending outward perpendicular to a main current direction defined on the resistor, and a sensing portion at the protrusion block.

  • Patent number: 11133813
    Abstract: An analog-to-digital converter (ADC) device includes an ADC circuitry and a digital slope ADC circuitry. The ADC circuitry is configured to generate first bits and a first voltage according to an input signal. The digital slope ADC circuitry is configured to generate a second voltage at a node according to the first voltage and to gradually adjust the second voltage to generate second bits. After the second bits are generated, the digital slope ADC circuitry is further configured to perform a noise shaping function according to a first residual signal of the node.
