A switch-mode power supply includes a first switch circuit, at least one second switch circuit, a switch control circuit, a first inductor switching circuit, a coupled inductor, a voltage input end, and a voltage output end. The coupled inductor in the switch-mode power supply may be connected to the first switch circuit, to implement signal transmission between the coupled inductor and the first switch circuit. Signal transmission between the coupled inductor and the second switch circuit may be implemented under control of the first inductor switching circuit. Alternatively, the signal transmission between the coupled inductor and the second switch circuit may be disconnected under the control of the first inductor switching circuit.

Switch-mode power supply

A voltage regulation apparatus and an overcurrent protection method are disclosed. The voltage regulation apparatus includes a current detection control circuit, a power stage circuit, a voltage input terminal, and a voltage output terminal. The power stage circuit includes at least one transistor. Because a current parameter indicates a load current of the at least one transistor, and a plurality of preset overcurrent protection thresholds are dynamic overcurrent protection thresholds obtained after being preset based on temperature information and the like, after obtaining the current parameter, the current detection control circuit compares the current parameter with the plurality of preset overcurrent protection thresholds, to output a control signal, to implement a limiting operation on the current parameter.

Voltage regulation apparatus and overcurrent protection method

The present disclosure relates to a detector apparatus. The detector apparatus may include a detecting module, an electronics module and a cooling assembly. The detecting module may be configured to detect radiation rays emitted from a subject and generate electrical signals in response to detection of radiation rays. The electronics module may be configured to process the electrical signals generated by the detecting module. The cooling assembly may be configured to cool the detecting module and the electronics module. The cooling assembly may include a first layer and a second layer. The first layer may be thermally connected with the detecting module, and the second layer may be thermally connected with the electronics module.

System and method for PET imaging

A method and device for secondary input of text are disclosed. The method may include: detecting a touch action, if the touch action meets a triggering requirement for a candidate split mode, activating the candidate split mode, and in the candidate split mode, selecting and splitting one of candidate results into an acceptable part and a pending part, wherein the acceptable part is presented in a target text field and a new candidate is acquired based on the character string corresponding to the pending part. With the present disclosure, users are allowed to modify a candidate result at any time as desired by retaining an accepted part of the candidate result during the input process, so as to simplify the input process. This entails a more prompt and more efficient input feedback mechanism which simplifies the user's manipulation and improves the user's experience.
