  • Publication number: 20230251722
    Abstract: The present invention relates to a gesture sensing system that uses characteristic point as a positioning starting point to generate coordinate information in space for a test object. The gesture sensing system includes: a light emitter, a light sensor, and a signal processing module. The light emitter emits a plurality of emitted lights to the characteristic point and the test object, and the emitted light is reflected to generate a plurality of reflection light to be received and converted by the light sensor receives into a plurality of sensing signal. Then, the signal processing module generates initial coordinate information and movement coordinate information based on the sensing signals. Finally, the signal processing module generates a gesture according to the initial coordinate information and the change between the movement coordinate information, and executes a preset function according to the movement trajectory of the gesture.

  • Patent number: 10761511
    Abstract: A printing method for biochip fabrication is implemented by a printing apparatus including a platform for supporting a substrate, a pipet module, and a control module. The method includes: moving the platform in sequence to multiple positions associated with multiple to-be-printed points on the platform; moving the pipet module reciprocatively toward and away from the platform during each movement of the platform; discharging, by the pipet module, solution sample onto the respective one of the to-be-printed points to form a bio-sensing spot to form a biochip; and determining, by the control module, whether to execute a supplementary printing procedure for the biochip based on whether each bio-sensing spot satisfies a predetermined criterion.

  • Patent number: 7557740
    Abstract: A decoding method is adapted to be implemented using a Context-based Adaptive Binary Arithmetic Coding (CABAC) decoding apparatus, and includes: initializing a plurality of context variables; storing the context variables; performing arithmetic decoding of a syntax element according to the context variables so as to output a decoded syntax element and an update signal; and updating at least one of the context variables according to the update signal. At least one of the context variables is pre-initialized in the initializing step before a bit stream ready.
