  • Patent number: 12334762
    Abstract: A system can include a battery pack with battery cell sections connected in series, where each of the battery cell sections includes a battery cell and a bypass switch. The system can also include a control circuit. The control circuit can determine a capacity of a particular battery cell in a particular battery cell section, determine that the capacity of the particular battery cell is less than a predefined threshold, and in response, execute a bypass sequence for the particular battery cell. The bypass sequence can involve determining a bypass period for which to bypass the particular battery cell based on the capacity of the particular battery cell, and transmitting a bypass signal to a drive circuit. The drive circuit can receive the bypass signal and responsively operate the bypass switch of the particular battery cell section to bypass the particular battery cell for the bypass period.

  • Publication number: 20250141360
    Abstract: The present invention provides a power controller, an asymmetric half-bridge power supply, and a control method, which are related to the field of electronic technology. The asymmetric half-bridge includes a charging switch and a resonant switch that constitute a half-bridge. The charging switch and the resonant switch are used to control the resonant circuit, which includes a transformer and a resonant capacitor. The asymmetric half-bridge power supply is used to provide an output voltage and to supply power to a load. The control method includes: providing a compensation signal based on the output voltage; turning on the charging switch for a charging switch turn-on duration; turning on the resonant switch for a resonant switch turn-on duration; and adjusting the resonant switch turn-on duration based on the compensation signal, so that the resonant switch turn-on duration increases as the load decreases.

  • Publication number: 20250141359
    Abstract: A switch-mode power supply is used to provide an output voltage and includes an inductor and a power switch, where the power switch is used to control the current flowing through the inductor. A control method for the switch-mode power supply includes: providing a compensation signal controlled by the output voltage; providing a stable compensation signal for the low-frequency component of the compensation signal based on the compensation signal; providing a mixed operation mode, in which the switch-mode power supply alternately operates during a switching operation period and an skip period, the power switch opens at least once during the switching operation period, and the power switch is closed during the skip period; based on the difference between the compensation signal and the stable compensation signal, ending one of the switching operation period and skip period, and starting another one of the switching operation period and skip period.

  • Patent number: 12248522
    Abstract: The present invention is a system and method for creating a digital and searchable inventory of physically stored, items, objects, or documents. Methods and apparatus of the present disclosure may image physical items as a person removes them from a container. This person may also provide verbal descriptions of items being imaged. Artificial intelligence, such as object recognition, optical character recognition, or natural language processing, may then applied to the captured data to classify the items into a searchable hierarchy. The digital classification of the items and their attributes may be linked to a machine-readable ID, such as a barcode or other identifier, that may allow the items scanned to be associated with a specific physical storage device. This may include using identifiers that were originally on a container and by associating new identifiers with the container.
