Abstract: A mode-changeable slim mouse includes a mouse body, a battery box casing and a connecting mechanism. Via the connecting mechanism, the battery box casing is connected to the mouse body and rotatable with respect to the mouse body. By rotating the battery box casing to different positions with respect to the mouse body, the mode-changeable slim mouse is operated in various operating modes.

Abstract: A separable and shape-changeable mouse includes a first housing, a second housing, a first connecting member and a second connecting member. The first housing includes a cursor signal generation unit, a first slant and a first connecting member. The second housing includes a receptacle for accommodating a battery therein, a second slant and a second connecting member. The first housing is combined with the second housing when the first connecting member is coupled with the second connecting member. By rotating the second housing with respect to the first housing, the shape of the mouse is changeable.

Abstract: The present invention relates to a keyboard with an optical cursor control device. The keyboard includes a plurality of keys and the optical cursor control device. These keys contain a space bar. The optical cursor control device may generate a cursor control signal by sensing movement of a user's finger. The optical cursor control device is arranged in the vicinity of the space bar. As a result, the user can operate the optical cursor control device without the need of considerably changing the hand gesture.

Abstract: A command input device for use with a digital data processing system and a portable communication apparatus includes a signal connector and a command generator. The signal connector is detachably plugged to a socket of the portable communication apparatus. The command generator is electrically connected to the signal connector and asserts a command signal to the digital data processing system via local wireless transmission modules of the portable communication apparatus and the digital data processing system.

Abstract: A wireless peripheral system for use with a computer includes a wireless signal transceiver controller and two peripheral devices. These peripheral devices include a human input device and an audio receive/transmit device, which are in communication with the computer via the wireless signal transceiver controller so as to communicate with the computer in a wireless transmission manner.

Abstract: A wireless cursor control device for use with a computer system includes a main body, a wireless signal receiver, a storing portion and a resilient pad member. The main body generates a wireless signal to control a cursor of the computer system. The wireless signal receiver is swappable to be electrically connected to the computer system for receiving the wireless signal. The storing portion is disposed in the main body for accommodating the wireless signal receiver. The resilient pad member is engaged with the bilateral sides of the storing portion, and deformed to generate a restoring force when the wireless signal receiver is inserted into the storing portion. The resilient pad member is sustained against the wireless signal receiver according to the restoring force.

Abstract: A pointing device includes a housing, a sensing circuit disposed within the housing for generating the pointing signals, a cable electrically connected to the sensing circuit for transmitting the pointing signals to the external device, and a reeling device disposed within the housing for reeling in or reeling our the cable. The reeling device is used to reel in excess portions of the cable outside of the housing, or to reel out additional portions of the cable within the housing.

Abstract: An encoder module for use in an input device of a graphic user interface (GUI) is disclosed. The encoder module includes a disk key disposed outside a housing of the input device, an upright shaft coupled to the disk key, an encoder consisting of a fixed contact electrode formed on a circuit board and a rotatable contact electrode sleeved around the shaft, and a switch consisting of a conductive electrode formed on the circuit board and a sheet conductor mounted on the circuit board and spaced from the conductive electrode. By exerting a rotating force on the disk key, the rotatable contact electrode rotates accordingly to exhibit different contact status with the fixed contact electrode so as to generate a signal indicative of a rotation quantity. By exerting a pressing force on the disk key, the sheet conductor is deformed to be in contact with the conductive electrode so as to generate a signal indicative of a conductive state to complete the input operation.

Abstract: An outage device and a surge-protection that uses the outage device, wherein the outage device is formed by connecting an overcurrent protection and an overheat protection in series, and packaged as a single device. As soon as either the current flowing through the overcurrent protection is too high or the temperature detected by the overheat protection is to high, the outage device forms a open circuit immediately to ensure that no currents are fed into the circuit. The surge protection is formed by connecting the foregoing outage device and a surge-absorbing device in series. The outage device and the surge-absorbing device have to be placed as close as possible, so that the outage device can open the circuit immediately as the temperature of the surge-absorbing device is to high to ensure that no currents are fed into the surge-absorbing device.
