Patent number: 12216169Abstract: A battery characterization system includes a drive-sense circuit (DSC), memory that stores operational instructions, and processing module(s) operably coupled to the DSC and the memory. Based on a reference signal, the DSC generates a charge signal, which includes an AC (alternating current) component, and provides the charge signal to a terminal of a battery via a single line and simultaneously to senses the charge signal via the single line to detect an electrical characteristic of the battery based on a response of the battery. The DSC generates a digital signal representative of the electrical characteristic of the battery. The processing module(s), based on the operational instructions, generate the reference signal to include a frequency sweep of the AC component of the charge signal (e.g.Type: GrantFiled: January 8, 2024Date of Patent: February 4, 2025Assignee: SIGMASENSE, LLC.Inventors: Patrick Troy Gray, Gerald Dale Morrison, Michael Frederick David Olley, Daniel Keith Van Ostrand, Richard Stuart Seger, Jr.

Patent number: 11671451Abstract: A secure communication channel is established between network devices separated by an unsecured physical space by dynamically performing server/client resolution based on comparison of unique identifiers of the devices. After a link between a first network device and a second network device is established, the devices exchange start frames in accordance with a network security protocol such as the Media Access Control Security (MACsec) protocol. Comparison logic at the first network device compares a value of a unique identifier of the first network device to a value of a unique identifier of the second network device obtained from the start frame transmitted by the second network device, and vice versa. Based on the comparison, one of the devices assumes a server/authenticator role, and the other device assumes a client/supplicant role. The devices operate in their determined roles to perform an authentication process and thereby establish a secure communication channel.Type: GrantFiled: August 5, 2019Date of Patent: June 6, 2023Assignee: Amazon Technologies, Inc.Inventors: Sanjeev Gupta, Frederick David Sinn, Venkata Satish Kumar Vangala, John Mark Glotzer
