Abstract: A wireless communications device, such as a cellular telephone (200), is able to accept and process DTMF tones as commands. Appropriate DTMF tones control operating characteristics of the wireless communications device (200). An example is causing a cellular phone to ring even though it has been configured into a “vibrate only” silent ring mode or a mode which has disabled all incoming call notification. Operation of such a DTMF tone facilitates finding a lost or misplaced cellular phone when that phone is configured to not ring in response to other calls. An external data communications port (232) of the wireless communications device (200) can also be controlled or data specified by the DTMF tone can be transmitted out of that data communications port (232).

Abstract: A method and apparatus for fast network acquisition suitable for use in a wireless communications unit that includes an antenna (10), a synthesizer (12), a receiver (14), a transmitter (15) and a controller (7). The antenna (10) receives a wideband signal (18) corresponding to a wideband channel including a plurality of narrower band channels. The controller (7) searches a base band signal (32) provided by the receiver (14) by dividing it into intermediate signals (124a-124d) corresponding to the plurality of narrower band channels to find narrower band channels with a synchronization pattern, and attempts to locate control channels corresponding to a base station server (6) within the narrower band channels with the synchronization pattern. One of the control channels having a most favorable signal characteristic is selected as an appropriate control channel and the transmitter (15) facilitates registration with a wireless network corresponding to the appropriate control channel.

Abstract: The invention provides a method and apparatus for achieving timing synchronization during signal acquisition and for achieving frequency synchronization in a digital communication receiver after signal acquisition.

Abstract: A work station that includes a mobile cabinet and a storage compartment. The storage compartment rests on top of the cabinet and is secured to the cabinet. The storage compartment projects beyond a periphery of the topside of the cabinet. The storage compartment includes a bottom, sidewalls and a lid. The bottom may be secured to the topside of the cabinet. The sidewalls extend upwardly from the bottom on three sides. The lid has a front from which extends a front side. The lid may be hinged to two opposing ones of the sidewalls and be swung between an open position and a closed position. Between the lid and the cabinet is a surface with an opening.

Abstract: A frequency management scheme for a hybrid cellular/GPS or other device generates a local clock signal for the communications portion of the device, using a crystal oscillator or other part. The oscillator output may be corrected by way of an automatic frequency control (AFC) circuit or software, to drive the frequency of that clock signal to a higher accuracy. Besides being delivered to the cellular or other communications portion of the hybrid device, the compensated clock signal may also be delivered to a comparator to measure the offset between the cellular oscillator and the GPS oscillator. The error in the cellular oscillator may be measured from the AFC operation in the cellular portion of the device. An undershoot or overshoot in the delta between the two oscillators may thus be deduced to be due to bias in the GPS oscillator, whose value may then be determined.

Abstract: A blood clot filtering system including an anchor which is permanently affixed in a blood vessel, and a filter which is removably attached to the anchor.

Abstract: An apparatus and method of simultaneously pressing different keyboard keys mechanically. The apparatus includes a displacement mechanism that is held by a main carrier that may slide back and forth along an elevated track. The displacement mechanism holds a further track. Further carriers may slide back and forth to desired positions along the further track. Each further carrier holds a rod, whose position relative to the respective further carrier is adjustable. Each rod has an end that constitutes a pressing surface. The displacement mechanism includes a plunger that may be manually pressed against spring bias to lower the further track and thereby the further carriers and the further rods. By doing so, the pressing surfaces of the rods may press against keys of different keyboards that are in alignment beneath the pressing surfaces.

Abstract: A GMSK modulated signal has a voice/data signal minimum shift key (MSK) modulated in time slots of the carrier signal. A mixing signal is used to demodulate at least part of the voice/data signal from the carrier signal for each time slot. A plurality of amplitude and phases of the demodulated voice/data signal are converted into a plurality of received quadrature data. The received quadrature data is processed to determine a frequency slope error value, a binary cyclical redundancy check (CRC) value, an average signal-to-noise ratio (SNR) value, a received signal strength indicator (RSSI) value, and a sequence of digital bits forming at least part of the voice/data signal. The frequency slope error value is weighted with a first weighting value or a second weighting value when the binary CRC value is in its first binary state or its second binary state, respectively, to produce a weighted frequency slope error value.

Abstract: A transmitter (200) has a compression detector for sensing the level of compression (110) in a signal that is being transmitted. The transmitter also has a radio frequency power amplifier (RFPA) (414) that is supplied by a supply modulator (426). The supply modulator provides a dynamic supply bias to the RFPA to maintain a desired amount of compression in the signal being transmitted. The supply modulator is responsive to a modulation signal (207) created by substantially following the envelope (214) of the signal to be transmitted (212). However, various signal and operational conditions can occur which cause the compression level to deviate (506) from the desired level. To maintain the desired compression level, the compression detector provides an output that is used to adjust the modulation signal from following the envelope of the signal to be transmitted in an unadjusted manner.
