Power supply failure detection system for various technical contexts
A recently filed patent (Publication Number: US20230384849A1) describes a non-transitory computer-readable storage medium that stores instructions for detecting an imminent failure in a power supply. The technology involves an internal computerized component within a device housed in a hermetically sealed environment, reading measurements from sensors affixed to the power supply. By analyzing these measurements using a weighted set of factors, the system can detect an imminent failure based on rising temperature and equivalent series resistance in electrolytic capacitors. The internal component can then inform a cable headend of the detected measurements, providing crucial information for maintenance and troubleshooting.
The patent also covers various applications of this technology, including Optical Line Terminals (OLT) nodes, 802.11n Wi-Fi Access Points, Ethernet switches, and power supplies for a range of devices such as Community Access television plants, outdoor Wi-Fi hot-spots, and wireless base stations. The system can transmit notifications of imminent failures over wireless networks or network links to software applications at the cable headend. By utilizing a combination of sensors measuring different parameters and updating weighted factors, the technology aims to improve the detection and prediction of power supply failures, ultimately enhancing the reliability and efficiency of various electronic devices and systems.
