  • Dual range tachometer
    Patent number: 6215298
    Abstract: A tachometer has a display responsive to an rpm signal for producing an observable indication of an rpm value. A circuit responsive to an engine input develops a standard rpm signal representative of instantaneous engine rpm, and a differential Power Band amplifier circuit amplifies the difference between the standard rpm signal and an adjustable “offset” rpm signal by predetermined gain to produce an amplified differential rpm signal. A switching circuit selects the standard rpm signal or the amplified differential rpm Power Band signal for driving the display. A peak or valley rpm signal may also be developed and selected for display either in a standard mode or a differentially amplified Power Band mode.

  • High performance tachometer having a shift indicator system with "short-shift" protection
    Patent number: 6137399
    Abstract: A high performance tachometer is provided for use in high performance racing vehicles, such as dragsters. The tachometer has an input signal indicative of the vehicular engine speed and an output display for displaying the instantaneous engine speed as indicated by the input signal. The tachometer includes input controls for directing the control and operation of the tachometer. Special features associated with the tachometer include a shift indicator. The system is designed to monitor an engine speed or RPM profile and utilize information from this profile to operate the shift setpoint selection, shift display enablement and the shift indicator.
