Title: Signal transfer unit with noise reduced by correlated double sampling
IPC: H03H19/00
Filed: 1994-04-06
Abstract: A circuit for eliminating the effect of noise in a signal transmission system eg by opto-coupler employs Correlated Double Sampling in the receiving sensor in conjunction with an active low-pass filter for reducing the system response bandwidth to stray light interference. Signal sampling is conducted in two non-overlapping phases (P1,P2) and during phase (P1) the transmitter diode (D1) is unenergised i.e. (51(2) is open and a voltage due to stray light only is received. During phase (P2) the diode (D1) is energised by closure of 51(2) and the signal lightflux combined with stray flux. The operational sequence of the switches (51 to 55) subtracts the two phased voltages to deliver a filtered nett signal (Vout) or closing 53(2).

Patent DE-4422184-A1 (DE)
Title: Motor vehicle controller with engine cylinder air-mass flow computer
Inventor: COSFELD RALF
IPC: F02D41/18
Filed: 1994-06-24
Abstract: The amount of air (mLSE) flowing past the throttle flap into the inlet manifold of the combustion engine is computed from a mathematical model involving the pressure (ps), vol. (vs) and temp. (Ts). The calculated pressure is subjected to adaptation (7) in accordance with the measured pressure so that a corrected value is input together with engine speed (n) into computation (6) of a characteristic factor (F2). The air flow (mLSA) into a cylinder is derived through division by the measured temp. Redundancy among the important parameters of the algorithm reduces the probability of system failure.
