Patent number: 11930573Abstract: A power supply device is provided. The power supply device includes a power converter and a controller. The controller controls the power converter to generate an output power. The controller includes a first detection circuit and a second detection circuit. The first detection circuit detects the output power to obtain a first detection result. The first detection result is a variation of an output current value of the output power. The second detection circuit detects electrical characteristics other than the output current value to obtain a second detection result. The controller determines whether to limit output of the output power according to a relationship between the first detection result and the second detection result.Type: GrantFiled: October 5, 2022Date of Patent: March 12, 2024Assignee: Power Forest Technology CorporationInventors: Rong-Jie Tu, Hung-Chih Chiu, Chien-Lung Lee

Patent number: 9706096Abstract: A method for taking photo with an extension flash module of a mobile device is provided in the present invention. The mobile device operates in coordination with an extension flash module to achieve fill light while taking photo. The method includes the following steps: detecting a specific event before a flashable period. The flashable period starts from the time at which a last row of photo sensors begins exposure to the time at which a first row of photo sensors ends exposure. The time at which the specific event occurs is a fixed period of time compared to the flashable time. Then, triggering a flash instruction according to a flash delay time and a period from the time at which the specific event occurs to the flashable time, such that the extension flash module flashes during the flashable time.Type: GrantFiled: March 10, 2015Date of Patent: July 11, 2017Assignee: EOSMEM CORP.Inventors: Ying-Yi Wu, Rong-Jie Tu

Patent number: 9392156Abstract: An extension flash module is provided in the present invention. The extension flash module adopts xenon flash light and is for attaching on the headphone jack of a mobile device. When the extension flash module operates, the voltage output from the headphone connector is boosted to provide a high voltage to the extension flash module. When the high voltage is charged to a rate voltage, the extension flash module sends a charging complete signal to the mobile device through the microphone terminal of the headphone connector. When shutter instruction is performed, the mobile device triggers the extension flash module to flash.Type: GrantFiled: August 28, 2015Date of Patent: July 12, 2016Assignee: EOSMEM CORPORATIONInventors: Hung-I Wang, Rong-Jie Tu
