Abstract: PROBLEM TO BE SOLVED: To differentiate between input ranges in a passive keypad.
SOLUTION: There are disclosed a method and circuit for processing switch closures in a passive network 100 having switches S1, ..., Sn. The passive network 100 generates an output voltage in response to a switch closure. The circuit includes a comparison circuit 206, coupled to the passive network, for comparing the output voltage to a reference voltage. A decoder 212, coupled to the comparison circuit, decodes the switch closure if the output voltage is within a predetermined range, and does not decode the switch closure if the output voltage is not within the predetermined range. The circuit differentiates between input ranges in a passive network keypad which allows the proper processing of meaningful key presses, while ignoring inadvertent or superfluous key presses, thereby conserving power and processor time.

Abstract: The process and apparatus of the present invention limits the output power of a radiotelephone, operating in a cellular system in the preferred embodiment. This ensures the transmitted sidebands and synthesizer phase noise remains within a certain specification. This is accomplished by power detection and a correction accumulator that together generate a gain control signal by limiting the gain adjustment to a maximum value, even when the cell site communicating with the radiotelephone is sending power turn-up commands to the radiotelephone. This process includes dynamically correcting the output level of the transmitter due to gain variations in the transmitter stages or gain control elements.

Abstract: A communications device that operates as a combination flip telephone and personal digital assistant (PDA). The opening and closing of the flip cover activates a switch that changes the operating mode of the communications device. The communications device operates as a combination wireless telephone and personal digital assistant (PDA) when the flip cover is open. This is called the SMARTPHONE mode of operation. When the flip cover is closed, the communications device operates as a standard wireless telephone. This is known as the KEYPAD mode of operation.

Abstract: A system for reducing receiver power consumption in communication system having a transmitter and one or more receivers schedules periodic messages in "slots." Each receiver is assigned a slot during which it monitors the transmissions. The transmitter transmits messages to the receiver only during the assigned slots. The receiver is in an "active state" during its assigned slot. It may remain in the active state after its assigned slot if the message requires the receiver to perform additional actions. During the "inactive state," which is the time period between successive occurrences of its assigned slot, the receiver may perform any action not requiring coordination with the transmitter. It may conserve power during this time by removing power from one or more components such as those used for monitoring the transmissions. At a time during the inactive state shortly before the assigned slot, the receiver applies power to these components and performs initializations. Such initializations may include reacquiring a pilot channel signal to which the receiver may synchronize itself if its timing signals have drifted out of synchronization with those of the transmitter during the preceding inactive state.

Abstract: The method and the device can be used in communications engineering, in particular in cellular communication systems having a transmitter and one or more receivers. They reduce the power consumption by the receivers. This can be made when for each receiver (122) a time interval is specified in which it observes the transmissions, i.e. is in active state. Transmitter (120) transmits messages (143) to the receiver (122) only when the latter is in active state. In any unactive state the receiver (12) can perform any operation which requires no coordination with the transmitter (12). By a power controller (147) it can switch off any components used for observing the transsmissions (14) . A little before the specified time interval, the receiver (12) supplies power to those components and performs initializations which can include the acquisition of a pilot signal (134) from the transmitter (120) by which receiver (122) synchronizes its clock signal (156) if that had not happened during the previous unactive state.
