Patent DE-19730851-A1 (DE)
Title: Method for simulating inertia forces using dynamometer
Inventor: FREITAG GERNOT
IPC: G05B17/02
Filed: 1997-07-18
Abstract: The method involves at least one roller to transfer a loading torque simulating an inertia force on the wheels of a vehicle. A loading device coupled to the roller generates the torque and both are connected to a torque sensor and to a speed sensor. The power output of the vehicle to the roller is determined as a function of the torque and speed signal provided by the transducers. As a function of the power output the load torque is determined from which a load control signal is derived for the automatic control of the load torque. An analogue with a closed loop structure is used to determine the vehicle power output. In its forward arm it has a controller for the analogue with a high signal gain and in its feedback arm a linear dynamic model of the controlled system of the dynamometer.

Patent DE-19806299-A1 (DE)
Title: Normalisation circuit arrangement
Inventor: MIYANISHI ATSUSHI
IPC: G06F5/01
Filed: 1998-02-16
Abstract: The circuit includes an AND gate (8) outputting the AND result of a reference signal, produced by a mantissa input, and an exponent input. An OR gate (9) calculates an OR combination of all bits output from the AND gate. A leading-bit detector (5) records the position of a leading one of the mantissa input and produces a signal if only one bit is set at the position. A priority encoder (2) subtracts one from the bit position value.    A one-bit shifter (21) shifts all bits of the signal from the leading-bit detector, with the exception of a highest-order bit, for one bit position toward the right. A selection circuit (7a) provides the output of the one-bit shifter as all bits of a control signal, with the exception of its highest-order bit, if the output of the OR gate is one, and a binary value of null if the output of the OR gate is zero.
