Patent number: 11632417Abstract: An IoT gateway with configurable data transmission mode includes a data collector, a data capturer and a data uploader. The data collector is configured to collect the data provided by a data provider based on a first data policy. The data capturer is configured to capture the data collected by the data collector based on a second data policy. The data uploader is configured to handle the data captured by the data capturer based on a third data policy. The first data policy, the second data policy and the third data policy may be configured separately according to different IoT applications.Type: GrantFiled: October 17, 2021Date of Patent: April 18, 2023Assignee: Moxa Inc.Inventors: Chi-Yuan Kao, Wen-Lung Hsu

Patent number: 11563589Abstract: A certificate management system includes an electronic device and a server. The electronic device is configured to transmit a certificate application request. The server is configured to sign a device certificate corresponding to the electronic device through an intermediate certificate device after receiving the certificate application request, and transmit the device certificate and the Internet address of the server to the electronic device. The electronic device stores the device certificate and the Internet address of the server to complete the certificate issuance operation.Type: GrantFiled: December 3, 2020Date of Patent: January 24, 2023Assignee: MOXA INC.Inventors: Chi-Yuan Kao, Yu-Chen Kao, Hung-Chun Chen, Chih-Hsiung Shih

Patent number: 11477038Abstract: A certificate transfer system includes a first certificate management host and a certificate transfer management host. The first certificate management host is configured to generate a first certificate, sign an electronic device with the first certificate, and transmit a first Internet address to the electronic device to complete a certificate-issuance operation. The certificate transfer management host is configured to store a transfer device list and a second Internet address. When the first certificate management host receives the first certificate issued by the electronic device, the first certificate management host verifies that the first certificate is correct and determines that if the first certificate matches one of the certificates in the transfer device list, the first certificate management host returns the certificate transfer management host address to the electronic device.Type: GrantFiled: January 12, 2021Date of Patent: October 18, 2022Assignee: MOXA INC.Inventors: Chi-Yuan Kao, Yu-Chen Kao, Hung-Chun Chen, Chih-Hsiung Shih

Patent number: 10955888Abstract: The present invention provides a universal serial bus (USB) device and an operating method thereof. The USB device includes a plurality of Downstream Facing Ports (DFPs) and a control circuit. When a first external device is connected to the first DFP and the second DFP is not connected to any external device, the control circuit maintains the first DFP as one of a power source port and a power sink port according to the first external device, and maintains the second DFP as other one of the power source port and the power sink port regardless of whether the second DFP is connected to a second external device later until the first external device is removed from the first DFP.Type: GrantFiled: August 15, 2018Date of Patent: March 23, 2021Assignee: VIA LABS, INC.Inventors: Tze-Shiang Wang, Chi-Yuan Kao
