Patent number: 11936418Abstract: A radar signal processing system with a self-interference cancelling function includes an analog front end (AFE) processor, an analog to digital converter (ADC), an adaptive interference canceller (AIC), and a digital to analog converter (DAC). The AFE processor receives an original input signal and generates an analog input signal. The ADC converts the analog input signal to a digital input signal. The AIC generates a digital interference signal digital interference signal by performing an adaptive interference cancellation process according to the digital input signal. The DAC converts the digital interference signal to an analog interference signal. Finally, the analog interference signal is fed back to the AFE and cancelled from the original input signal in the AFE processor while performing the front end process, reducing the interference of the static interference from the leaking of a close-by transmitter during the front end process.Type: GrantFiled: April 27, 2021Date of Patent: March 19, 2024Assignee: KAIKUTEK INC.Inventors: Mike Chun-Hung Wang, Chun-Hsuan Kuo, Mohammad Athar Khalil, Wen-Sheng Cheng, Chen-Lun Lin, Chin-Wei Kuo, Ming Wei Kung, Khoi Duc Le

Publication number: 20240084621Abstract: A security lock has a fixing element and at least one hook. The fixing element is mounted in a security slot of an electronic device. The hook is capable of moving axially with respect to the fixing element, and the hook moves radially outward along a guiding structure of the fixing element to engage with the security slot, the fixing element stays static, i.e., without moving and rotating as the hook is moving. Therefore, the security lock won't press the security slot, and further prevents damage to the security slot caused by frequently or constantly loaded with the security lock. Furthermore, without moving and rotating in a mounting process of the security lock, the fixing element holds the hook to steadily engage with the security slot, and thus an overall anti-pulling and anti-pushing performances are enhanced.Type: ApplicationFiled: July 17, 2023Publication date: March 14, 2024Inventors: Chien-Hung WU, Chia-Hung WANG
