Patent number: 11769348Abstract: A face recognition method for an edge device is provided. Firstly, a recognition data is received from a computing device through a wireless network. Then, a trained model is retrieved from the recognition data. Then, the trained model is stored. Then, a face detection operation is performed to acquire a face image and a face temperature of a detected face. When the face temperature is within a human body temperature range and the face image complies with the trained model, the edge device confirms that the detected face is a face of a real person and the real person is a known user.Type: GrantFiled: August 24, 2021Date of Patent: September 26, 2023Assignee: DIGITAL SYSTEM INTEGRATION CO., LTD.Inventors: Yu-Kai Kuan, Yu-Che Tsai

Patent number: 10484857Abstract: An access point (AP) accepts a communications device to join a wireless communications network. The AP registers a service provided by the communications device. The service is available in accordance with a schedule and a set of service parameters. The AP receives a request from a peer communications device seeking the service. The AP announces availability of the service on behalf of the communications device while the communications device is unavailable. The service is later provided by the communications device to the peer communications device when both devices are available to communicate. By utilizing an always-on AP to announce service availability and to exchange service parameters, fast service discovery can be achieved with low power consumption for both service advertisers and service seekers.Type: GrantFiled: August 13, 2015Date of Patent: November 19, 2019Assignee: MediaTek Inc.Inventors: Yu-Che Tsai, Chao-Chun Wang

Patent number: 10104186Abstract: A device-centric discovery mechanism requiring very low power consumption to find out information about each other directly in a self-managed mobile environment is proposed. A mobile communications device joins a self-managed communications network, which does not have a centralized management entity. The mobile device receives a request from a peer communications device about publishing a service or subscribing to a service in accordance with a first schedule. The mobile device announce the request on behalf of the peer communications device in accordance with a second schedule. The service is then provided by a service advertiser to a service seeker in accordance with a third schedule.Type: GrantFiled: August 13, 2015Date of Patent: October 16, 2018Assignee: MediaTek Inc.Inventors: Yu-Che Tsai, Chao-Chun Wang, Yung-En Hsieh, I-Cheng Tsai
