    Abstract: A press-buckled lock having a press buckle is used so that the operation of locking and unlocking can be performed rapidly. By pressing the buckle, the door can be locked rapidly. When the inner handle is rotated, the press buckle is separated rapidly to unlock. Other than making the operation easy, the installation of the press buckle at the inner handle of a lock will reduce the manufacturing cost and cause the operation to be easy. Thereby the cost is reduced. By pressing the press buckle, a lock can locked rapidly; when rotating the inner handle or inserting a specific key into the lock core, the press buckle will separate rapidly so as to unlock the lock; thus, the press buckle in the lock has the effect of controlling the locking and unlocking operation rapidly.

  • Publication number: 20110070882
    Abstract: A mobile phone utilizes a radio frequency (RF) chip transceiving RF signals via a front end circuit. A power detector detects power output from a power amplifier and converts the power to voltage to transmit to a central processing unit (CPU). A base station tester measures output power of the mobile phone and transmits to the CPU in a test mode. A microwave chamber measures power radiated by the antenna in an operation mode. A high voltage circuit provides a high voltage signal continuously. A detection circuit detects a connection status of the base station tester and the testing connector and outputs the high voltage signal to the CPU according to the connection status. The CPU determines an operating mode of the mobile phone based on output of the detection circuit, and outputs a maximum output power according to the test mode and operation mode maximum output power calibration tables.

  • Patent number: 7903617
    Abstract: A method and system for multi-user wireless communications between a sender and a receiver enables effective blocking of interference signals by other senders and improving the channel data rate. The receiver uses two or more receiving devices, such as antennas or smart antennas, to receive multiple wireless input signals. By performing a noise-transparent autocorrelation matching analysis on the multiple input signals, the receiver derives an anti-interference filter for interference-blocking action, without the need for information of the interfering and its transmission channel. In a multi-user environment, the noise-transparent autocorrelation matching analysis is implemented by the Autocorrelation Division Multiple Access (ADMA) system that includes the design and the implementation of ADMA code, the ADMA encoder, the ADMA algorithm and the ADMA decoder.
