Publication number: 20250167690Abstract: A full-bridge power converter is provided. The full-bridge power converter includes a transformer circuit, an input-side circuit, an output-side circuit, and a controller. The input-side circuit includes an input-side full-bridge circuit and an input inductor. The input-side full-bridge circuit includes multiple power switches. The input inductor is coupled between a positive power terminal of the battery module and the input-side full-bridge circuit. The output-side circuit includes an output-side full-bridge circuit and an output capacitor.

Patent number: 12150781Abstract: Devices detect and assist in the avoidance of blood vessels during a surgical procedure—to avoid rupturing these blood vessels. Devices may be any penetration sensor device (such as a dilator sensor device, hollow needle sensor device, or trocar sensor device) that penetrates the skin and subcutaneous layers to reach a target location inside the body. The device includes a sensor probe which can make optical measurements to determine various parameters of the tissue at the tip of the sensor probe. These parameters may include an optical signal level returned from tissue contacting the tip of the sensor probe, an oxygen saturation level of the tissue, a total hemoglobin concentration, a blood flow, and a pulse. Based on these parameters, the presence or absence of a blood vessel at the tip of the device can be determined while the device travels towards the target location for surgery.Type: GrantFiled: April 11, 2023Date of Patent: November 26, 2024Assignee: ViOptix, Inc.Inventors: Robert E.

Publication number: 20240241185Abstract: This disclosure provides an estimation method applied to a state of health of a battery, which executes a recharging to a battery when a battery voltage is lower than a threshold voltage. During the recharging, a battery state of health estimation procedure is performed from a first depth of discharge detection point to a second depth of discharge detection point. During the battery state of health estimation procedure, a voltage difference between a current battery voltage and an initial open-circuit voltage is accumulated over time from the first depth of discharge detection point to the second depth of discharge detection point to obtain an accumulation of current sampled voltage difference. An accumulation of estimated DC internal resistances can be equivalently obtained by the accumulation of current sampled voltage difference. Afterwards, the state of health of the battery can be determined based on the accumulation of estimated DC internal resistance.Type: ApplicationFiled: July 11, 2023Publication date: July 18, 2024Inventors: Wen-Fan Chang, Chun-Chieh Li, Shih-Fa Hung, Jian-Min Chen
