    • A unique dual-bandwidth cellular telephone includes a transceiver (100) having a dual bandwidth receiver, an audio/logic unit (200) having dual control programs, and a handset unit (300). The dual bandwidth receiver of the transceiver (100) has different filters (408 and 410) in the intermediate frequency section thereof which are switchably selected depending on which cellular telephone system is available. When service is not available in one of the cellular telephone systems, the unique cellular telephone automatically switches the receiver bandwidth and control program for operating on the other cellular telephone system.

    • An RF tagging system which provides a large number of potential identification codes without increasing the physical size of RF tags used therein includes a plurality of RF tags (20, 90, 140, 230, 250) and an external reader (200). Each RF tag includes at least one resonant circuit (22, 92, 142, 231, 251) which is resonant at any one of a plurality of different frequencies, a receiver (34, 102, 152,244, 264) for receiving an interrogation signal, and a control (36,104,154,246, 266) responsive to receipt of an interrogation signal for causing its at least one resonant circuit to be resonant at selected ones of the different frequencies in a predetermined time sequence corresponding to a predetermined identification code. The external reader includes a detector (216, 218, 220, 222) for detecting the selected resonant frequencies of the RF tags and a decoder (226) for decoding the time sequence of the selected resonant frequencies for recovering the predetermined identification code.

    • A technique for fabricating a patterned resistor on a substrate produces a patterned resistor (101, 801, 1001, 1324, 1374) including two conductive end terminations (110, 810, 1010) on the substrate, a pattern of first resistive material (120, 815, 1015) having a first width (125) and a first sheet resistance, and a pattern of second resistive material (205, 820, 1020) having a second width (210) and a second sheet resistance that at least partially overlies the pattern of first resistive material. One of the first and second sheet resistances is a low sheet resistance and the other of the first and second resistances is a high sheet resistance. A ratio of the high sheet resistance to the low sheet resistance is at least ten to one. The pattern having the higher sheet resistance is substantially wider than the pattern having the low sheet resistance. The patterned resistor can be precision trimmed 1225.

    • There is provided a mechanism for error detection comprising: detecting the symmetry of error distributions over adjacent time intervals and muting of a radiotelephone in response to detected loss of substantial symmetry, unless errors are attributable to valid alternative detections. It is further characterized by: detecting the symmetry of error distributions over adjacent time intervals and muting a radiotelephone as a corrective response to detected consequential asymmetry or loss of substantial symmetry (unless errors are attributable to alternative detections of valid synchronization words) and cancelling any such corrective response upon subsequent alternative detections of valid synchronization words.
