Patent number: 11921101Abstract: Disclosed are calibration techniques that can be implemented by a device that conducts biological tests. In certain embodiments, the device for testing a biological specimen includes a receiving mechanism to receive a carrier, a camera module arranged to capture imagery of the carrier, and a processor. Some examples of the processor can detect a calibration mode trigger. In calibration mode, the processor can divide the captured imagery into segments and selectively perform one or more calibration procedures for each segment. Then, the processor records a calibration result for each segment.Type: GrantFiled: January 25, 2022Date of Patent: March 5, 2024Assignee: Bonraybio Co., Ltd.Inventors: Cheng-Teng Hsu, Chih-Pin Chang, Kuang-Li Huang, Yu-Chiao Chi, Chia-Wei Chang, Chiung-Han Wang
