Abstract: A method for monitoring the performance of a catalytic converter (34) computes the oxygen storage capacity and desorption capacity of a catalyst within the catalytic converter (34). An engine control unit (10) receives mass flow rate information of air from a mass air flow rate sensor (12) and an injector driver (24), and receives electrical signals from an upstream exhaust gas sensor (28) and a downstream exhaust gas sensor (30). The engine control unit (10) calculates normalized air fuel ratios for the exhaust gas entering and leaving the catalytic converter (34) and performs numerical integration to determine the oxygen storage capacity and oxygen desorption capacity of the catalyst in the catalytic converter (34). The calculated oxygen storage and desorption capacities of the catalyst are compared with threshold values to determine the performance of the catalytic converter (34).

Abstract: In order to derive accurate DR heading information from the wheel speed, the distance between the centers of the tires, or the wheel track, must be known to high precision. Unfortunately, the wheel track may not always be known to a high level of accuracy whereby different classes of the same vehicle type can produce variations of up to 5 %. This current invention removes the error growth associated with wheel track error by automatically estimating and calibrating the wheel track. The wheel track is measured by computing a heading rate directly from the GPS Doppler measurements, and comparing it with the heading rate derived from the wheel sensors whereby subsequent refinements to the estimated wheel track are computed by filtering each measured track.

Abstract: A selective call communication system (10) transmits a frequency hopped spread spectrum signal as a Reed Solomon code word modulated as a four-level frequency shift keying (4FSK) signal. A base site transceiver (150) receives the signal on a plurality of narrow band channels and a DSP (152) performs an FFT on the signal. The DSP (152) has a comparator (342) that computes energy of a 4FSK symbol. The comparator (342) establishes a ratio of a maximum energy and a next largest energy to an eye-opening threshold to indicate a probability of error. A determinator (344) in response to the probability of error determines when there is a fade, an erasure marker (346) marks a position of a Reed Solomon symbol in the fade as an erasure and error correcting code (348) corrects errors in the Reed Solomon code word with the marked erasure.

Abstract: In a wireless communications system (20), a beacon having a first radiation pattern (28) covering a portion of a subscriber service area (34) covered by a base station is transmitted. A subscriber (36) reception quality is then measured to produce a first beacon quality measurement (210). Thereafter, the first radiation pattern is changed to a second radiation pattern (32, 212), and a subscriber reception quality of the beacon transmitted with a second radiation pattern is measured to produce a second beacon quality measurement (214). In response to the first and second beacon quality measurements, a traffic channel radiation pattern (32) is selected (218), wherein such radiation pattern covers a portion of the subscriber service area. In a preferred embodiment, the beacon carrier frequency is the same as the traffic channel carrier frequency.

The receiver (100) includes a mixer (102) for mixing the multi-level FSK signal to generate an in-phase signal and a quadrature signal, and a demodulator circuit (110) coupled to the mixer (102).
