Patent number: 6736102Abstract: A method for operating an internal combustion engine and a corresponding device are described, in which reference pulses are generated synchronously with respect to the cyclical movement of at least one part of the internal combustion engine. At least one event moment for the occurrence of at least one event is calculated by an output unit at specific, definitively preset time intervals of the cyclical movement. Moreover, an independent clock-pulse generator is provided which generates clock pulses, the interval of the clock pulses being independent of the movement, and the interval of the clock pulses being smaller than the interval of the reference pulses. The at least one event moment is expressed as the number of clock pulses of the independent clock-pulse generator, and the at least one event is triggered upon reaching the number of clock pulses.Type: GrantFiled: September 3, 2002Date of Patent: May 18, 2004Assignee: Robert Bosch GmbHInventors: Johann Konrad, Martin Haussmann, Harry Friedmann

Patent number: RE28775Abstract: An electronic, undamped oscillator driven by a periodic input signal (forcing function) having a frequency equal to the natural frequency of the oscillator develops an output sinusoidal signal having a rate of growth (amplitude increase) proportional to the amplitude of the first harmonic component of the input signal. When the input signal is a force variation signal and the oscillator is tuned to the rotational frequency of a tire mounted on the force variation machine, the rate of growth of the output signal of the oscillator is proportional to the amplitude of the force variation signal. A peak follower detects the amplitude of the increments between successive peaks of the oscillator output signal. A meter indicates the amplitude of the successive peaks of the oscillator output signal, thereby indicating the amplitude of the first harmonic component of the force variation signal.Type: GrantFiled: March 1, 1971Date of Patent: April 20, 1976Assignee: Uniroyal Inc.Inventors: Haig D.
