    摘要: A digital tone generator (1110) includes a digital signal generator (1138) which generates a digital waveform data sequence which is representative of a tone having a predetermined waveform, and a pulse-width modulator (1132) which provides an adaptive duty cycle period (622, 630) which is responsive to the digital data waveform data sequence for selecting clock pulses of a number sufficient to generate a pulse-width modulated digital tone signal. The digital tone generator (110) can also include a low pass filter (36) which processes the pulse-width modulated digital tone signal to generate an analog tone signal. The digital waveform sequences generated by two digital tone generators (38, 40) can be digitally added by a digital adder (28) to provide a composite tone data signal, which can be processed by the adaptive pulse-width modulator (700) to produce a pulse-width modulated tone signal representative of a DTMF tone.

    摘要: A mobile communication device (100) includes a volatile memory (110) and a non-volatile memory (112). Instruction code for operating the mobile communication device is permanently stored in the non-volatile memory, and copied to the volatile memory for execution. The mobile communication device enters a hibernate mode which involves shutting down most of the mobile communication device except power to the volatile memory, which allows a nearly instant apparent start up of the mobile communication device at a later time.

Alternatively, the method can send (16) rate plan information for the originating to the terminating party and compare rate plans at the terminating party. The method can pre-store (20) rate plan information for the originating party at a memory at the terminating party. The method can also use (24) Caller ID to detect a call from the originating party and compare pre-stored rate plan information for the originating party stored at the terminating party.

    摘要: A method for limiting transmission power of a communication device (600). The method can include determining a desired maximum transmission power and determining a plurality of power contribution factors. Each of the power contribution factors can be associated with a respective service active on the communication device. The method also can include determining an expected transmission power based on, at least in part, a sum of the power contribution factors. Further, in response to the expected transmission power exceeding the desired maximum transmission power, the power contribution for at least one of the services active on the communication device can be selectively reduced or terminated. Selectively reducing the power contribution can include reducing a bit rate of a service data stream for the service and/or reducing a duty cycle of a service data stream for the service. Selectively terminating the power contribution can include terminating the service.

    摘要: A visual display device (10) coupled to a processor (22), a memory (16, 18) and a counter (14) produces procession of displayed alphanumeric characters until a consecutive sequence of at least four numeric or punctuation characters is displayed, at which time the procession stops prior to any character of the at least four consecutive numeric or punctuation characters processes off a viewable portion of a visual display (12). The procession remains stopped until a user of the visual display device intervenes to cause resumption of procession. The visual display device gradually slows the rate of procession when words of at least five consecutive alphanumeric characters are displayed, and gradually increases the rate of procession when words of at least five consecutive alphanumeric characters are no longer displayed. A selective call receiver (11) includes a receiver (23) and the visual display device (10) to display received wireless messages.
