摘要:
In a computer with a plurality of wireless input devices, a communication system and a method identify the input signal from the plurality of input devices. The computer includes a receiver to receive RF signal from the wireless input devices. The wireless input devices of different categories will use different communication channels. For example, mice use the first communication channel, keyboards use the second communication channel. The input signal is prefixed with an ID code comprising a category field and a serial field. The same input signal will be consecutively sent in many cycles in a first time slot and the receiver will receive the input signal in a second time slot shorter than the first time slot. The receiver will sequentially receive a plurality of inputs signal in a plurality of receiving cycles, and discriminate the input signal through the ID code.

A method and an apparatus for controlling a digital electronic product, using a control signal transmitter and a signal receiver combined with a gate system for controlling a digital home appliance, such that a system activation/inactivation control mechanism is established. The on/off status of the gate system is remotely controlled by the control signal transmitter. In the process of switching off the gate system, a basic input/output system (BIOS) for executing switching on/off is used to detect whether the external connecting port is connected to a signal receiver. When the system is in the off status, the electric connection to the signal receiver is maintained, such that the activation control signal from the control signal transmitter can be received any time. Thereby, the signal status of the signal receiver can be changed to automatically switch on the gate system, and the control signal transmitter can thus remotely control operation of the digital home appliance.

A mouse control structure, which forms a receiving space recessed from a top surface of a mouse. The receiving space is used to receive a control panel, which has a control key, a direction key, and an audio transceiving port. The control key, direction key and the audio transceiving port are used to control and integrate electronic devices such as DVD, TV, VIDEO, CD and recording pen. A covering plate is used to cover the receiving space, such that a complete mouse device is obtained.

The present invention provides a wireless receiving device jointly used by computer peripherals and a method thereof. The wireless receiving device comprises a wireless receiving circuit, a micro-processing circuit, and an interface circuit. The micro-processing circuit can receive wireless signals emitted by wireless emitting devices of different computer peripherals via the wireless receiving circuit, and has a learning procedure. The learning procedure can be activated to let the micro-processing circuit memorize and lock on a specific wireless emitting device. The signal processed by the micro-processing circuit is then transferred to a computer via the interface circuit.

A switch device disposed in a handheld apparatus having a keypad with double function is capable of automatically switching to one function by means of sensing directionality of the apparatus. The handheld apparatus has a keypad whose some keys bear double function. The switch device in the apparatus has a gravity sensor for detecting a distribution of gravity of the apparatus along three coordinate axes. The senor sends a gravity signal to a controller, which judges a direction of the apparatus being disposed. The controller sends a switching signal to the keypad. The keys with double function are then switched to one function corresponding to the judged direction.
摘要:
An automatic frequency hopping remote controller automatically switches its channel when the transmission of a remote control signal is interfered. The remote controller includes a transmitting end and a corresponding receiving end; the transmitting end includes a first signal transceiver capable of transmitting signals through several channels and an input device, such that the remote control signal can be transmitted from a predetermined channel by a trigger instruction of the input device, and the receiving end is a second signal transceiver installed in an electronic device for receiving the remote control signal from the transmitting end. If the quality at a received signal is evaluated as poor, the remote controller will automatically switch to another receiving channel and send a frequency hopping signal to the transmitting end, so that the transmitting end will switch to that channel correspondingly, and the next remote control signal will be transmitted through that channel.

A single-band remote control for controlling different categories of remote devices, and multiple remote devices of the same category, the remote control has a plurality of control keys divided into a plurality of frequency groups. The control keys of the same frequency group are operative to generate and transmit control signals with different identification data at the same frequency, while the control keys of different frequency group are operative to generate control signals with different frequencies within the same frequency band. Thereby, different types of remote devices and/or multiple remote devices of the same category can be controlled by the same remote control.
摘要:
A method of preventing interference of signal transmission of electronic input devices, using a receiving unit that has multiple frequency channels to connect a host. The receiving unit is accompanied with software program to set up one sequence of frequency-hopping channels for each type of electronic devices such as mouse, keyboard, remote control and audio input device. The software program also defined one of the frequency-hopping channels. as a starting receiving frequency channel. When a signal is transmitted from a specific type of electronic devices, the receiving unit switches the frequency to its starting receiving frequency channel for receiving such signal. When the signal has been interfered, the receiving unit automatically hops the frequency to the next available hopping frequency channel of the specific type of electronic devices until the interference is eliminated.
