Patent number: 11530991Abstract: A method to process an image to determine a biological property associated with a test strip (221, 313, 323, 333, 413, 423, 513, 523) in a test strip adaptor (120, 220, 620, 720). The method includes receiving the image captured by a mobile computing device (100, 600, 700) and determining whether the received image includes sensitive information. In response to determining that the image includes sensitive information, the method further includes overwriting the image with a later received image before the image can be saved as a file. In response to determining that the image does not include sensitive information, the method further includes identifying a characteristic configuration associated with the test strip (221, 313, 323, 333, 413, 423, 513, 523) and determining the biological property based on the image and the characteristic configuration.Type: GrantFiled: May 29, 2019Date of Patent: December 20, 2022Inventors: Yenyu Chen, Chien Hsun Chen, Yao Ching Tsai

Patent number: 9579805Abstract: A brake device of a robot arm utilizes a brake disc whose diameter is much larger than a diameter of a ratchet for increasing a contacting area of the brake disc, so as to generate a greater friction force. The brake device further utilizes a combining pin, a combining plate, and a plurality of guiding pins for transferring a rotating torque to the brake device having a larger diameter, so as to extend a moment arm of the friction force and generate a greater moment, which reduces a prepressing force and extends life of the brake device.Type: GrantFiled: October 29, 2015Date of Patent: February 28, 2017Assignee: QUANTA STORAGE INC.Inventors: Yao-Ching Tsai, Jen-Chen Wu
