Patent DE-2809316-A1 (DE)
Inventor: SAKOE HIROAKI
IPC: G10L19/00
Filed: 1978-03-03
Abstract: A frequency analyzer of a predetermined number of channels comprises a digital band-pass and a digital low-pass filter section. A preselected number of digital samples sampled with a sampling period are stored in a buffer memory to be read out in each sampling period. A band-pass parameter memory memorizes for the respective channels band-pass filter impulse responses, each having preselected values, equal in number to the preselected number. A band-pass filter calculator calculates a convolution of each read-out digital sample and the preselected values of each response. The low-pass filter section produces frequency analysis results for the respective channels in each analyzing frame period equal to a first prescribed number of the sampling periods. A low-pass filter impulse response having a duration equal to the frame period multiplied by a second prescribed number and prescribed values, the predetermined number in each sampling period, is memorized in a low-pass parameter memory with its phase or the duration successively shifted by the frame period. A multiplier calculates products of each convolution and the prescribed values of the respective memorized responses read out in an interval of production of that convolution. Absolute values of the products are accumulated in an accumulator register memory according to the respective channels and the respective phases and produced therefrom as the analysis results for the respective channels in those of the sampling periods which are spaced by the frame period and at which the respectively shifted durations have ends, respectively.

Title: Vehicle seat power adjustment system - has two motors, cam and traction disc together with stops to define setting movement
Inventor: WIRTZ EGON
IPC: B60N2/02
Filed: 1978-11-29
Abstract: One of the intermediate gearing members associated with the motors (24, 36) has an entrainment cam which can draw along at least one loosely rotatable traction disc (50). There is also a cam which in turn in the end rotary position adjoins the fixed stop cam so as to define the setting movement. Stops for limiting the setting path can now be positioned directly in the motor area where the tilt moment which arises as the motor rotor starts up is not yet substantially increased by the reduction of the adjustment mechanism. The tilt moment need therefore not be considered when designing the adjustment mechanism so that the gearing members can be made smaller for a more economic mass production.

Title: Crosspoint switching marker for telephone exchange - has relay with transistor switch to operate crosspoint connection and apply busy signal to others
Inventor: BERNARD KLAUS
IPC: H01H63/40
Filed: 1979-08-09
Abstract: Marker circuitry is for crosspoint switching the matrix in a telephone exchange. The object is cost reduction of the marker relay system controlling the inlet/outlet crosspoint switching of the matrix, i.e. 'p' wire control. The crosspoints in the control matrix have inlets (b1-b4) and outlets (a1,a7) with polarised relay circuitry (R,R1,Rx,Ry) at the crosspoint. The inlets are marked with a minus potential (B1--B4) and the outlets with an earth (A1). Such marking condition (e.g. A1 earth, B1-ve) energises the crosspoint relay (R) through the associated rectifiers (G2,G3) (and G1). The transistor circuit (T) cannot conduct and the relay operates. All other crosspoints on the same inlet are then barred because current is fed via associated rectifiers (e.g. Gy1,Gy2) to switch on the transistors and block the relays, preventing operation.
