  • Publication number: 20240071428
    Abstract: A device is disclosed and includes an input stage circuit, a switching circuit, and a first latch circuit. The input stage circuit generates a first input signal having a first voltage and a second input signal based on a third input signal. The switching circuit operates in response to a first control signal, and adjusts a voltage level of a first data line according to the first input signal and a voltage level of a second data line according to the second input signal. The first latch circuit is coupled to the switching circuit by the first data line and the second data line. The first latch circuit latches a data in response to the first control signal and a second control signal, and adjusts the voltage level of the first data line based on a second voltage different from the first voltage.

  • Publication number: 20220327729
    Abstract: An object positioning system and an object positioning method are provided. The object positioning system includes a sensing device, a storage device and a processing device. The sensing device collects point cloud data obtained from a scene including a target object. The processing device inputs surrounding area data centered on a key point and a preset feature descriptor to a neural network to calculate a scene feature descriptor of the scene. The processing device performs feature matching between the scene feature descriptor and the preset feature descriptor, and calculates a position of the target object in an actual space. The invention utilizes the feature extraction capability of the neural network to effectively improve the accuracy and stability of target object identification and positioning.
