Patent EP-0638819-A2 (EP)
Inventor: SCHUERMANN JOSEF H
IPC: G01S13/75
Filed: 1994-08-11
Abstract: A method for interrogating remote transponders having the steps of: sending an RF interrogation pulse from an interrogator (10), receiving by a first and second transponder (12,12a) the RF interrogation pulse, and establishing in a resonant circuit (130) of each of the transponders (12,12a) an oscillation, the oscillation being established by the coupling of signal energy from the RF interrogation pulse into the resonant circuit (130). After the RF interrogation pulse ends, the first transponder (12) senses the termination of the pulse and initiates a first RF response having a selected duration. A second RF response from the second transponder (12a) will also be detected in the first transponder (12) whose response will be affected by this second RF response. The differing response times in the first transponder (12) for responses affected and unaffected by neighboring transponders may be sensed in the interrogator so the interrogator may detect instances in which the RF responses which it received may have been conflicting.

Abstract: The handover method disclosed relates to mobile communication system in which, based on the number of handovers in mobile units, the size of the radio zone to be assigned to a mobile unit is selected. The mobile switching center (100) measures the number of handovers in each of the mobile units (120) engaging in communication and, during the handover in the mobile unit, the handover target radio zone is assigned based on the measured value of the number of handovers. The target handover of mobile units is determined by the target determination controller (102) based the number of handovers memorized in the handover number recorder (103). The assignment of the appropriate size radio zone prevents an excess load on the mobile switching center and the capacity to accommodate subscribers in the mobile communication system is enhanced.

Abstract: The path speed is controlled to prevent overload of the electrical drive as a result of reducing torque at higher revolution rates. An acceleration characteristic is achieved with constant high torque at constant acceleration. In the region of high axial speeds acceleration limiting is performed taking account of the revolution rate or speed at which the drive torque reduces and so that the acceleration also reduces depending on the torque. Defined demand and target speeds at defined target times are continuously matched to the changed acceleration characteristics.

Abstract: In an audio signal processing circuit for carrying out a subband coding used for an audio signal coding, a subband filter 12A receives 1152 audio samples (SI) of each one frame and divides the samples into 32 frequency bands to sequentially outputs a train of first half subband signals (SFA) for a first half of the one frame and a train of second half subband signals (SFB) for a second half of the one frame. A FFT circuit (111A) carries out an FFT processing for 512 audio samples of each of the first half and the second half of each one frame, to sequentially generate a first half power spectrum (PSA) and a second half power spectrum (PSB). A calculating circuit (113A) calculates a first half SMR signal (SMA) on the basis of the first half subband signals (SFA) and the first half power spectrum (PSA), and then, a second half SMR signal (SMB) on the basis of the second half subband signals (SFB) and the second half power spectrum (PSB). A comparing circuit (115) outputs a larger one of the first half SMR signal (SMA) and the second half SMR signal (SMB), as an SMR signal (SM) for the whole of a corresponding one frame.
