Abstract:
A device and method for controlling an electric lock control the electric lock by generating a password signal carrying an ID information from an electronic apparatus including a communication chip. The device includes an antenna unit, a communication unit, a processing module, and a memory unit. The processing module receives the password signal from the electronic apparatus via the communication unit and the antenna unit. The processing module controls a locked status of the electric lock based on the password signal. The ID information carried by the password signal is analyzed by the processing module and sent to the memory unit and stored therein to form a reference information. Once the processing module receives the password signal again, the processing module will determine whether to maintain or change the locked status of the electric lock based on a result of comparison of the password signal and the reference information.
Abstract:
A remote controller switching device is used with a smart handheld electronic device installed with a control program providing a remote controller interface. When manipulated, the remote controller interface allows the control program to generate an operation instruction for controlling remotely an intended target. The remote controller switching device includes a fixation base for fixing the smart handheld electronic device in place, and a remote control module having a transmission connection portion and a protocol portion. After creating a transmission connection to the smart handheld electronic device, the remote controller switching device generates a remote control signal based on the operation instruction to control the intended target remotely through the protocol portion.
Abstract:
An overvoltage protection circuit protects a portable electronic device against overvoltage. The overvoltage protection circuit includes an input unit for receiving an input voltage supplied by a voltage source; a voltage-divider module for dividing the input voltage and outputting a divided voltage; a voltage-regulator module for comparing a comparison voltage with the divided voltage and generating a first control signal; a first switch unit being controllably switched by the first control signal to a short-circuit state or an open-circuit state and generating a second control signal; and a second switch unit being controllably switched by the second control signal to a circuit state reverse to that of the first switch unit, and stopping supplying the input voltage to the portable electronic device when the input voltage is no less than a rated voltage of the portable electronic device. Therefore, a temperature-independent overvoltage protection can be achieved.
Abstract:
A carrying device for carrying a plurality of handheld electronic devices includes a plurality of carrying units and at least a connecting unit connected between the carrying units. The handheld electronic devices are disposed in a receiving space of the carrying units, such that respective display screens of the handheld electronic devices are grouped together to display. The handheld electronic devices carried by the carrying units are rotatable, stay at a fixed angle, or shut relative to each other by the connecting unit. The carrying device allows the handheld electronic devices to be positioned side by side so as to extend the display screens, display more data, or enlarge data, thereby enhancing performance and protecting the handheld electronic devices.
Abstract:
A single-cable bidirectional communication-based touch control display method and system for enabling communication and transmission between a portable electronic device having a first medium access address and a touch control display device having a second medium access address are provided. The method includes sending a video signal generated by the portable electronic device to the touch control display device via a single transmission cable to display the video signal on the touch control display device; touching, by a user, the touch control display device based on the video signal to generate a touch signal configured as a data packet according to an Internet Protocol frame; and sending the data packet back to the portable electronic device via the transmission cable, such that the portable electronic device retrieves the touch signal from the data packet to generate and feed another video signal back to the touch control display device.
Abstract:
A multi-testing procedure management method tests on a testing platform a plurality of function units of a plurality of devices under testing (DUTs) by a test schedule management list enumerating a plurality of schedule items. The method includes determining, by comparing the schedule items on the test schedule management list, whether the schedule items are directly applicable to testing the function units; keeping the schedule items in case of affirmative determination; and deleting the schedule items in case of negative determination. The method further includes selecting existing built-in items from a test library or creating and adding new test items to the test schedule management list to eventually produce a revised version of the test schedule management list for testing the DUTs. A multi-testing procedure management system is further provided.
Abstract:
A standby power system for handheld electronic device and a method for supplying standby power are introduced. The system and method enable detection whether a handheld electronic device is set to a predetermined power consumption state whereby the handheld electronic device operates in a power supplying state of a standby battery and whether a main battery of the handheld electronic device is disconnected, allowing a user to change the main battery without shutting down the handheld electronic device and thereby saving time.
