Abstract: There is provided a locker with a motion sensor. The motion sensor identifies whether an object is put into or taken out from the locker by calculating coordinates of the object using a motion detection algorithm, by calculating a moving vector of the object using an image time differential algorithm or by comparing a current image frame and a background image frame, and outputs a put-in signal and a taken-out signal to a post control system.

Abstract: A motion detection method applied into an image sensor device includes: providing a plurality of regions of interest (ROIs) on at least one monitoring image; for each region of interest (ROI): detecting whether at least one motion event occurs within the each ROI; and determining a priority level of the each ROI according to at least one feature information of the at least one motion event; and determining an alarm schedule of the ROIs for a user according to a plurality of priority levels of the ROIs.

Abstract: A subtitle processing method includes a subtitle parsing step and a subtitle reading step. The subtitle parsing step includes: dividing a subtitle file into a plurality of subtitle blocks, each of the subtitle blocks including a plurality of subtitle contents, each of the subtitle contents corresponding to a subtitle time; generating an index table that records characteristic times of the subtitle blocks. The subtitle reading step, for reading a target subtitle content corresponding to a current time, includes: identifying a target subtitle block corresponding to the current time and the characteristic times recorded in the index table; and reading the target subtitle content of the target subtitle block according to the current time.

Abstract: A Bluetooth data transmission system and method is provided. The system includes a computer comprising a USB port, a keyboard, and an embedded resident program; and a USB dongle releasably connected to the USB port for communicating with the computer, the USB dongle comprising a USB communication module, a MCU, a Bluetooth device communication module, and a USB-to-Bluetooth protocol translator.

Abstract: System and method of recognizing a touch event on a resistive touch pad having virtual keys are provided. The system includes a touch sensitive unit in the touch pad; a touch area calculation unit; and a microprocessor. In response to pressing the one of the virtual keys by an object, the touch area calculation unit measures a touch area of the object on the virtual key, the touch area is compared with a predetermined value, the touch area calculation unit generates a touch signal if the touch area is greater than the predetermined value, the touch signal is transmitted to the microprocessor, after receiving the touch signal, the microprocessor generates a key code corresponding to the virtual key being pressed, and the key code is transmitted to a computer for further processing to recognize the touch event.
