Abstract: A method for operating a mouse wheel of a mouse of a computer according to a position of a cursor pointer of the mouse is provided. According to the method, a software is used to partition a screen frame or a software window frame into at least two sub-fields. Each of the sub-fields is corresponding to a predetermined related mouse wheel functional operation instruction. When a cursor pointer of the mouse is moved into one of the sub-fields, and while the mouse wheel is in operation, the predetermined related mouse wheel functional operation instruction corresponding to the sub-field in which the cursor pointer is instantly located is then initiated and executed.

Abstract: A set of headphones switchable to a sound box mode of operation comprises two ear shells each of which has a speaker. An inner chamber of each ear shell is configured with a transmission line of Helmholtz resonance. A vent aperture of the transmission line is located on an outer case of each ear shell. A cord having a connector plug is connected with the speakers in the ear shells. A portion of the cord is also provided with an audio power amplifier connected between the connector plug and the speakers. A switch is also provided, operable to switch an audio signal outputted to the speakers between different levels of power.

Abstract: A mouse having a shake-elimination function when leaving a working plane is provided. A light sensing unit detects a light emitted by a light emitting unit toward a working plane or a column shaped member, and outputs a detection signal. A microprocessor determines whether the mouse is apart from the working plane according to the detection signal. When it is determined that the mouse is positioned apart from the working plane, the microprocessor clears the displacement amount obtained from the communication interface of the optical displacement sensor, and meanwhile the microprocessor inform the computer that the mouse is apart from the working plane. In such a way, when the user lifts the mouse up from the working plane, the displacement signal outputted from the optical displacement sensor won't cause the cursor shake.

Abstract: A method for executing a predetermined command associated with a mouse gesture includes the steps of: (1) recording a motion track of the mouse; (2) calculating a distance of the motion track of the mouse; if the distance is less than a predetermined value, returning to step (1); (3) transforming the motion track from rectangular coordinates to polar coordinates represented by a distance and an angle, in which the polar coordinate system is divided into eight angle regions, determining which angle region the angle of the polar coordinates is located in, and executing a predetermined command corresponding to the region in which the angle is located, wherein the eight regions are defined as N×45°±22.5°, and N is one of integers 0, 1, 2, 3, 4, 5, 6, and 7; (4) clearing the recorded mouse motion track, or subtracting the predetermined value from the recorded mouse motion track, and returning to step (1).

Abstract: An input device for executing an instruction code and method and interface for generating the instruction code are disclosed. The method for generating an instruction code which is executed by an input device includes the steps of: opening a specific purpose programming interface which is used for simulating to show a plurality of corresponding buttons according the input device; selecting a corresponding button waiting for being defined and entering a programming window; selecting any instruction for the corresponding button waiting for being defined to form a combined operation instruction in proper sequence; compiling the combined operation instruction to form an instruction code which can be executed by the input device; and downloading the instruction code to the input device. Accordingly, the input device can show a continuous operation action when the corresponding button waiting for being defined is pressed.

Abstract: An extendable mouse with an extension pole includes a bottom housing and a top housing. The top housing includes a forepart and a back part, the forepart covers the bottom housing, or, the forepart is in-molded with the bottom housing, a flexing sheath connects the forepart and the back part, and an extension pole is set inside the back part. The back part, the flexing sheath, and the extension pole joint extensionally with the forepart. The back part covers the bottom housing and can be pulled relative to the bottom housing. The shell of the extendable mouse of the present invention can be extended backwards more conveniently. The entire size of the mouse and the mini mouse especially when used for notebook computers is increased. Hence, integrality and the sense of looks are improved.

Abstract: A cursor control apparatus that allows a user to double-click the left key. A second left key is added to the traditional cursor control apparatus. The user can press the second left key once to achieve the multi-clicking effect. The speed of performing shooting actions in a game application or processing a document file in a computer is thereby increased.

Abstract: A roller structure for a computer mouse has a roller member with a concave portion formed on a circumference surface thereof. The concave portion is concaved from top to bottom of the circumference surface of the roller member to form an arcuate shape. Furthermore, the roller structure can be provided for ergonomics and a simple design, and to decrease operational injuries to a user's finger.

Abstract: A rechargeable receiver for receiving the signal from a wireless transmitter of a computer peripheral device such as a keyboard or a mouse and has a built-in recharger for recharging the rechargeable batteries used in the computer peripheral device with the wireless transmitter.

Abstract: A wireless mouse and keyboard assembly comprises a wireless mouse and a keyboard. The wireless mouse has a wireless emitter therein and emitting a wireless signal. The keyboard has a wireless receiver receiving the wireless signal from the wireless emitter. The keyboard converts the received wireless signal to a digital signal, which is sent to a computer through a connection cord connected between the keyboard and the computer. The wireless mouse and keyboard assembly has reduced space and cost.

Abstract: A keytop of keyboard is proposed. The keyboard has a main typing area on which a plurality of key tops is placed. The key tops are divided into a plurality of rows by a plurality of horizontal lines. The key tops are divided into a left-hand section and a right-hand section with a centerline of the keyboard as a border. Each key top in the left-hand section is of quadrilateral shape with right-shifted topside and left-shifted bottom side; each key top in the right-hand section is of quadrilateral shape with left-shifted topside and right-shifted bottom side.

Abstract: A keyboard assembly comprises a typing section, a function key section at top side of the typing section, cursor and screen-control section at right side of the typing section and a number/editing section at right side of the typing section. Therefore, user can use right hand for operating mouse while using left hand for operating the number/editing section, thus saving labor of right hand and enhancing operation efficiency.
