    摘要: There is disclosed an input device including a display for displaying a plurality of icons, and a selector for selecting a displayed icon. At least a portion of the display is an electronic display. The device is adapted such that the selector moves relative to the display between a plurality of positions. At least one position corresponds to a displayed icon. The device further includes a function selection means. A function associated with an icon corresponding to a current position of the selector is selected when the function selection means is enabled.

    摘要: A passive mixer includes a transconductance amplifier having a source degeneration capacitance. The transconductance amplifier has an input for receiving an input signal and an output for outputting a current signal. A multiplier is provided for mixing a local oscillator signal with the current signal so as to provide an output signal at an output of the passive mixer. A capacitive load is connected to the output of the passive mixer.

    摘要: A system for, and method of, obscuring ambient noise. In one embodiment, the system includes: (1) a background sound generator, (2) a mixer coupled to the background sound generator and (3) a user interface, coupled to the mixer, that, upon a user command, causes the mixer to mix an output of the background sound generator with a transmitted signal. The background sound may be music, white noise, colored noise, out-of-phase ambient noise, simulated alternative ambient noise or any other suitable background sound. The system may be associated with a wireless handset, a wireline handset, central office equipment or any other suitable location or equipment.

    摘要: A method and apparatus are provided for wireless communication between an integrated circuit device and a monitoring station. Each integrated circuit device has one or more antennas that permit wireless communication with an external monitoring station. A signal destined for an integrated circuit device is transmitted by the monitoring station using an associated antenna. An antenna associated with the destination integrated circuit receives the transmitted signal. The antenna(s) may be embodied, for example, as pins that are external to the integrated circuit device, or printed or etched on the integrated circuit device itself. Greater bandwidth can be achieved, if necessary, by pooling the bandwidth of several antennas.

    摘要: Techniques are disclosed for automatic generation of a location-indicative instruction displayable to one or more users in a communication system which includes a wireless network comprising a plurality of user devices adapted for communication with at least one access point device. A test of a communication link between at least one of the user devices and the access point device is initiated. Based at least in part on a result of the test, an instruction displayable to a user associated with a given one of the user devices is generated, the instruction being indicative of a location at which the given user device is expected to obtain a particular level of data throughput performance.
