摘要： A method for processing signals of a tire pressure monitoring system on vehicles on each of whose N wheels (R1 through R5) a transmitter is mounted and a reception antenna (1 through 5) which is connected to the input of a common receiver (8) is allocated to each transmitter in its vicinity, the transmitters transmitting, at time intervals, data telegrams which contain an individual identifier and a data portion following the latter. The signals received simultaneously from the reception antennas (1 through 5) and having the same identifier are conveyed in summed fashion to the receiver (8), alternately from all N reception antennas (1 through 5) and from N-1 reception antennas (1, 2, 4, 5), such that the one reception antenna (3) whose signal is blanked out of the sum of the signals is selected by cyclical transposition from the total number N of reception antennas (1 through 5). Then the intensity of the summed signals is determined, the intensity of the sums of N-1 signals is compared in each case to the intensity of the sum of N signals, and an identification is made of that reception antenna (3) from which the signal has come whose blanking from the signal sum brings about the greatest intensity loss (D1 through D5). Lastly, the signal having the relevant individual identifier is allocated to that reception antenna (3) and to the wheel (R3) allocated to it.

摘要： A method for operating a device for monitoring and indicating a pressure change in vehicle tires by wire, being preferably arranged in the tire as one module together with the tire valve, and comprising a current source, a pressure sensor arranged for measuring the tire pressure at first time intervals, an analog/digital converter for digitizing a pressure signal obtained from the pressure sensor, a memory for storing the pressure signal, a transmitter for transmitting the measured tire pressure information to a receiving unit located in the vehicle, a comparator, especially one realized in one module with a microprocessor, which compares the pressure signal with a previously stored comparison pressure signal and controls the transmitter in such a way that the transmitter will transmit signals at second time intervals greater than the first time intervals, so long as the decrease of the pressure signal, relative to the comparison pressure signal (drift), does not exceed a threshold value, but will transmit signals at third time intervals smaller than the second time intervals when and so long as the drift exceeds the pressure threshold value; to this end the second time intervals are varied in response to one or more physical conditions that are measured in the tire and that vary in driving operation.

摘要： An arrangement made up of an electrical circuit board (7) and an electrical pressure transducer (1) which has, in a housing (2), a pressure sensor onto which the pressure to be measured is transferred by means of a fluid through a channel (5) leading into the housing (2), and from which there proceed electrical lines which project out of the housing (2) as leads (4) and are connected to the circuit board (7). The channel (5) is shielded on the outer side of the housing (2) so that the flow resistance for fluid entering and leaving the channel (5) increases.
