摘要： A user interface (210) includes an RC circuit (213). The RC circuit (213) includes a variable capacitance. The variable capacitance is produced by a sensing member (310) in cooperation with a user's finger (311). When a user makes a selection with the user interface (210), the user places a finger (311) in close proximity and in a facing relationship to a section, or discrete surface (320, 322, 324), of the sensing member (310). The discrete surfaces (320, 322, 324) can correspond to keys of a keypad (138) or to directions of a directional button (1030), for example. The time constant of the RC circuit (213) varies according to which discrete surface (320, 322, 324) is determining the capacitance of the RC circuit (213). A controller (118) determines the user's selection based on the time constant of the RC circuit (213).

摘要： A bus interface and corresponding method is provided for conveying communication signals supporting multiple modes, where at least two of the modes have distinct operational communication signal levels. The bus interface is adapted to convert the communication signals between communication signals having distinct signal levels, and communication signals having compatible signal levels. Where in at least some instances, the conveyed communication signals are converted from communication signals having distinct signal levels to communication signals having compatible signal levels, and then back to communication signals having distinct signal levels, after the communication signals having compatible signal levels are transmitted and received via one or more associated communication paths.

摘要： An apparatus and method to reduce uplink compressed mode monitoring in a communication device includes a first step of monitoring a neighboring channel and measuring a channel signal strength. An desense of the monitoring receiver is estimated to determine a threshold, which is compared to the signal strength. If the signal strength is less than the threshold, a new neighboring channel is monitored to see if the signal strength changes. If not, the measured signal is probably interference. In this case, the communication device can request uplink compressed mode to get an accurate signal strength measurement. Only under these condition are uplink compressed mode called for, instead of full time compressed mode, thereby maintaining data capacity.

摘要： A method (1400) of enabling automatic frequency control (AFC) concurrent with time alignment of information in a communication device includes a first step (1402) of providing a data stream to an AFC. A second step (1404) includes applying multiple frequency offsets to the data stream. The offsets are separated from each other by about ±2&pgr;/2m radians with m being the number of bits per symbol in the modulation system. A third step (1406) includes correlating each frequency offset signal with a predetermined symbol sequence until correlation is found. A fourth step (1408) includes coupling the correct data stream of the branch with the found correlation to an AFC logic circuit indicating AFC lock. A fifth step (1410) includes simultaneously supplying the correct data stream to the communication device along with the fourth step (1408) such that time alignment can take place concurrently with AFC in the communication device.

摘要： A phase-locked-loop circuit for a radio transceiver operative to transmit and to receive modulated signals during nonconcurrent time periods. During time periods in which the radio transceiver is to generate and to transmit a modulated signal, the phase-locked-loop circuit is connected to the transmitter portion of the transceiver. During time periods in which the radio transceiver is to receive a modulated signal, the phase-locked-loop circuit is connected to the receiver portion of the transceiver. A switch, preferably comprised of a multiplexer, alternately connects the phase-locked-loop with the transmitter portion and the receiver portion of the transceiver.
