Abstract: An electrical power conversion device, a function triggering circuit for the electrical power conversion device, and a function triggering method for the electrical power conversion device are provided. The function triggering circuit is coupled between the secondary side of the transformer and the control module and includes a current detection circuit, a delay circuit and a switching circuit. The current detection circuit senses the secondary side of the transformer to generate a detection signal of delay. Before steady-state duty of the transformer, the delay circuit causes an initial level to be higher than an internal level. After steady-state duty of the transformer, the switching circuit selectively generates a function triggering signal according to the detection signal. The function triggering signal is for triggering the control module to carry out an overcurrent protection operation.

Abstract: A webcam capable of generating special sound effects includes an image device, a sound device, a multiplexer, a microprocessor, and a universal serial bus device. The image device is used for capturing and processing an image to generate a processed image. The sound device is used for capturing and processing sound to generate processed sound. The multiplexer is coupled to the image device and the sound device for receiving the processed image and the processed sound. The microprocessor is used for controlling the image device and the sound device. The universal serial bus device is used for controlling the multiplexer to read the processed image from the image device and read the processed sound from the sound device according to a command of a host, and transmitting the processed image and the processed sound to the host.

Abstract: The present invention provides an electronic lock structured to include a first bolt configured with an elastic clasp, an electromagnetic device connected to an input device, a second bolt and a microswitch connected to a security system, all of which are installed interior of a housing of the electronic lock. The elastic clasp is retained by a protruding edge of the housing, thereby disenabling the first bolt from an arbitrary retracting movement that would otherwise render the lock incapable of being unlocked. The input device controls the electromagnetic device to induce the elastic clasp and release a retaining state, and then directly rotating a rotating button causes a retracting movement of the first bolt and unlocking of the electronic lock, which simultaneously disconnects the security system.

Abstract: A safe electromagnetic lock including a first bolt provided with an elastic fastener, an elastic slide bolt positioned on an end of the first bolt, an electromagnetic device connected to a computer and a second bolt. The computer controls induction of the elastic fastener by the electromagnetic device, and a key inserted into a first keyhole, or another key inserted into a second keyhole, controls sliding movement of the elastic slide block to push against the elastic fastener, thereby releasing an abutting state and effecting unhindered unlocking of the safe electromagnetic lock. Upon unlocking, a front end of the second bolt extends out from a case, and protruding mount of the second bolt is used to press down on a steel ball, thereby enabling the second bolt to achieve a solid fixation and effectively preventing mistakenly locking and avoiding forgetting to lock the safe electromagnetic lock.
