A high-speed digital interface (HSDI) transceiver with bi-directional HSDI function includes a transmitter, a receiver, a first multiplexer, and a controller. The first multiplexer is selectively coupled to the transmitter or the receiver in order to let the HSDI transceiver act as a source device or a sink device respectively. The controller is coupled to the first multiplexer for controlling a switching operation of the first multiplexer. When the HSDI transceiver is connected to an HSDI source device, the controller controls the first multiplexer to couple to the receiver to let the HSDI transceiver act as the sink device, and when the HSDI transceiver is connected to an HSDI sink device, the controller controls the first multiplexer to couple to the transmitter to let the HSDI transceiver act as the source device.

An apparatus for processing input signals includes a signal receiver, a comparator, first and second drivers, and a calculator. The signal receiver is used for receiving input signals. The comparator compares the input signals with predetermined signals and generates unit signals representing a corresponding comparison result. The first driver generates first drive signals according to the unit signals. The calculator generates a result signal according to the unit signals. The second driver generates a second drive signal according to the result signal.

A loudspeaker includes a basket defining a center hole therethrough, a conduction wire board fixed to the bottom surface of the basket, a magnet placed on the basket, a diaphragm arranged on the basket and above the magnet, and a voice coil. The conduction wire board defines a core hole corresponding to the center hole, and two welding foils on the bottom surface. The magnet defines a through hole corresponding to the center hole. The voice coil is wrapped around the magnet and fixed to the bottom of the diaphragm. The voice coil has leading wires, which bend inward at the top and downward pass through the through hole of the magnet, the center hole of the basket and the core hole of the conduction wire board, and then extend toward two sides of the rivet for being welded on the corresponding welding foils.

A method for allocating session key across gatekeepers in a direct-routing mode, including the following steps: a caller's GK and a callee's GK allocate a session key for a caller and a callee between through a Diffie-Hellman (DH) negotiation. The method of the present invention can allocate the session key even when the caller does not support the DH negotiation, therefore it has a wide range of applications.

A general short-range remote control alerting system consists of at least one transmitter or encoder device in communication with at least one receiver or decoder device. Each transmitter or encoder device has a factory pre-set unique identification (ID) code. The receiver or decoder device utilizes a memory device, the memory of which will not change due to power supply interruption and can be read or written or re-written to store ID codes from the various transmitters or encoder devices. The transmitter or encoder device transmits ID code to the receiver or decoder device, and upon matching, the receiver or decoder device causes pre-defined functions to be performed, such as a musical tune to be played or a light to be activated or de-activated. A communication protocol realizing the above system is also disclosed.The present invention can be applied to doorbells, security lights, home controls and security alarm systems.

A protractor and ruler combination includes a main ruler having a side formed with a protractor, a secondary ruler rotatably mounted on the main ruler, and an auxiliary ruler having a side secured on the secondary ruler, so that the secondary ruler is moved in concert with the auxiliary ruler on the protractor of the main ruler. Thus, the auxiliary ruler is moved relative to the main ruler, and the secondary ruler is moved in concert with the auxiliary ruler on the protractor of the main ruler, so that the included angle between the ruler section of the main ruler and the ruler section of the auxiliary ruler is measured exactly.

摘要:
In order for a user to be able to hold a narrow frame or even frameless handheld device on its front touch-screen display, configure a full-screen grip area on the front touch-screen display when no human hands are holding and/touching the touch-screen display. The grip area is ready for holding and will be reduced to be much smaller when a human hand holds the handheld device on the grip area of the touch-screen display. When the grip area is not required, reducing the grip area to be a tiny area located at a corner or an edge of the touch-screen display by a predetermined touch operation, for example, a swipe gesture in the grip area. And when the grip area is required again, restore the grip area by a predetermined touch operation, for example, a drag gesture on the tiny grip area at a corner or an edge of the touch-screen display.
