Abstract: A radar altimeter (10) incorporates circuitry for automatically adjusting altitude readings for variations caused by altitude and temperature changes. Normal target tracking (32,20,15) of the radar is intermittently interrupted and a calibration sequence is interjected. The current altitude and receiver AGC information at the time of each interruption is temporarily stored (56,101) and a test is initiated in which a pseudo radar return at that altitude is introduced to the receiver (28). The receiver operates on the pseudo return as it would on an actual return. The transmit power is adjusted automatically for the correct signal level at the tracker. The resultant altitude measured for the pseudo return is compared to a known test altitude and any difference is stored (52) away as a correction factor to be applied to the altitude reading which had been stored at the time that its operation had been interrupted to perform the calibration test.

Abstract: An apparatus and technique for measuring and analyzing the tread wear of a pneumatic tire. The tire is indexed about its axis. Between the indexing steps, a laser scanner obtains data from the tread surface. This data is normalized to eliminate any out-of-roundness of the tire data. Noise spikes are removed and replaced with values attributable to valid data. From the data, a reference curve corresponding to a lateral sector of the tire is devised. The data from actual lateral sectors is then compared to the reference curve by a curve-fitting process and the deviation between the actual data and the reference curve establishes the degree of irregular wear of the tire at that lateral point.

Abstract: The process according to the invention is characterised in that the suspension systems are actuated during braking and/or acceleration manoeuvres in such a way that at each wheel unit the instantaneous normal force between tyre and carriageway, the wheel load, is influenced in the direction of its largest possible value. For this purpose, the characteristic of the wheel load, in particular the dynamic portion, is determined from the sensed movements between the wheel units and the body of the vehicle and/or from the sensed movements of the wheel units. Results of a frequency analysis of the wheel loads and the time characteristic, in particular the time derivation of the wheel load, are used to adjust the suspension systems in the direction described above. In the chassis control system according to the invention, the suspension systems between vehicle body and the wheels are actuated during braking and/or acceleration manoeuvres in such a way that the average spacing between the body of the vehicle and the wheel units becomes progressively smaller over time during the braking and/or acceleration manoeuvres. <IMAGE>
