    摘要: A method and system for data wireless systems on computers, for using the same cable to bi-directionally transmit antenna signals as well as other signals to and from the inside of a shielded computer housing. An example of a control signal is a connect signal for establishing initial contact between the computer and a remote wireless device. An example of a control signal transmitted from inside the computer housing to the outside, is a signal for lighting an LED. Antenna signals are separated from the control signals based on differences between these signals, for example, differences in frequency. In one embodiment, a capacitor filters out a DC control switch signal, while the high frequency antenna signal is filtered by the normal input pin circuitry of a processor.

    摘要: Methods and devices are disclosed for selectively varying the load to a photodetector such as a phototransistor which forms part of a photosource/photodetector pair and for selectively using to advantage or compensating for the parasitic capacitance of the photodetector to permit reductions in power, conversion of fixed signal thresholds to software controlled digital hysteresis, automatic adjustment and compensation for unmatched photosources and associated photodetectors, and adjustment of fixed voltage thresholds.

    摘要: A set of wireless devices can be coupled together using a radio frequency identification (RFID) system. The system includes an RFID writer for writing a unique identifier to an RFID tag stored in a transmitter device. The unique identifier can then be used to identify a wireless signal sent from the transmitter device to a receiver device. The receiver may also include an RFID tag, and the two devices may share a secret encryption key for use in creating an encrypted link between the transmitter and receiver. Virtual links may also be established at a distribution center by writing an address through a closed box into each device RFID. One or more RFID writers may be used to verify the identifier written to the RFID tags, carry out quality control checks, and track products to prevent inventory leaks and verify that sold products are certified.

    摘要: The present invention provides a wireless radio frequency ("RF") communications interface between peripherals and the host personal computer or workstation. In one embodiment, the present invention provides a wireless electronic mouse which uses an RF transmitter to transmit information unidirectionally to a receiver which is coupled to a host computer. This arrangement eliminates the need for a cable connection between the mouse and the receiver, while at the same time permitting continuous communication therebetween. The present invention also provides a method and apparatus to allow the receiver to differentiate between multiple RF wireless mice operating within the same transmission zone by a combination of providing a unique identification code to each transmitting mouse and allowing the user to choose from a plurality of transmission channels. The receiver then automatically switches to the channel selected by the user. The present invention can further receive transmissions from either one or two peripheral devices. In one device mode, the receiver filters out stray frequencies from other RF peripherals. In two device mode, the receiver has the ability to receive information from two RF peripherals, while filtering out other stray RF peripherals operating in the same transmission zone. This allows a user to use the same receiver for one peripheral, such as a mouse, for detailed work and another peripheral for other types of special applications, such as a pointing device for software presentations. The present invention further provides for a power consumption minimization method in the wireless peripheral.
