Title: Method and apparatus for determining relative contributions of individual cylinders of internal combustion engine using contact tachometer
Inventor: BRAUN ROBERT D
IPC: G01M15/04
Filed: 1991-10-15
Granted: 1999-07-27
Abstract: A linearly moving external part on a multi-cylinder internal combustion engine is contacted with a hand-held rotary encoder, contact tachometer having a hollow handle in which processing circuitry is disposed for converting the rotary encoder output to a waveform signal.  This signal, along with a signal responsive to the firing of the number one cylinder, are applied to an engine analyzer processor for display of a single engine cycle of the waveform signal on the CRT oscilloscope of the engine analyzer.  The variations in amplitude of the waveform signal correspond to speed variations of the moving part over an engine cycle to give an indication of the relative power contributions of the individual cylinders.

Title: Active energy control for diode pumped laser systems using pulsewidth modulation
Inventor: NIELSEN KEITH E
IPC: H01S3/115
Filed: 1994-01-20
Granted: 1999-03-16
Abstract: An active energy control circuit and method employing pulsewidth modulation for use with diode pumped laser systems. The active energy control circuit and method employs optical energy feedback sensing and output control of the electrical pulsewidth to pump diodes of the laser system. This creates an active energy control loop for maintaining diode pumped laser output energy at a desired level over different pulse repetition frequencies, time, and environmental conditions. The diode pumped laser output energy is controlled by varying the pulsewidth of the output energy pulse while maintaining a current amplitude set point. By using a pulsewidth-modulation-based control system, the current applied to the pump diodes is regulated at an efficient set point below their damage level, and the pulsewidth is adjusted to maintain a desired output optical energy of the laser system. The pulse width modulated output energy control scheme provided by the present invention is appropriate for all diode pumped laser applications including laser rangefinders, laser designators, laser radar systems, laser welding systems, and other low and high power laser systems.
