  • Publication number: 20250141170
    Abstract: A brush module for a rotary table includes: a housing, a brush unit, a first pushing unit and a second pushing unit, the brush unit includes a brush disposed in the housing, a conductive wire electrically connected to the brush, and a pushing force for pushing the brush towards the opening of the housing. The first and second pushing units oppositely provided on the housing provide the brush a first and a second pushing forces in opposite directions to resist the lateral thrust generated by friction between the brush and the rotary disk of the rotary table, thereby greatly reducing the vibration, shaking, slipping, line contact and other conditions of the brush caused by high-speed rotation of the rotary disk, avoiding damaging the peripheral surface of the rotary disk, and maintaining good electrical contact between the brush and the rotary disk.

  • Publication number: 20250124282
    Abstract: An image classification system is provided for determining a likely classification of an image using multiple machine learning models that share a base machine learning model. The image classification system may be a browser-based system on a user computing device that obtains multiple machine learning models over a network from a remote system once, stores the models locally in the image classification system, and uses the models multiple times without needing to subsequently request the machine learning models again from the remote system. The image classification system may therefore determine likely a classification associated with an image by running the machine learning models on a user computing device.

  • Patent number: 12249068
    Abstract: A health management system using contactless physiological measurement technology is disclosed. The health management system principally comprises a camera and a first processor, of which the camera is faced to a user for capturing a user image. The first processor is particularly configured to have a face detection unit and an activity index calculating unit therein. By such arrangement, after receiving the user image from the camera, the first processor detects a face portion from the user image, thereby subsequently extracting a PPG signal from the face portion. Consequently, after completing at least one process of the PPG signal, multiple indexes for describing a user's health activity are generated. The health activity indexes include health index, activity index, stability index, relaxation index, metabolism index, and balance index. Therefore, the first processor achieves an evaluation of the user's health activity state according to the forgoing health activity indexes.

  • Publication number: 20250072143
    Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.
