Title: Method for eliminating sensor drift in a vibration monitoring system
Inventor: TWERDOCHLIB MICHAEL
IPC: G01M99/00
Filed: 1988-03-01
Granted: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE    A method is disclosed for eliminating aberrations in position-time data provided by an apparatus which monitors the position of a rotating blade in a turbo machine as a function  periodic  rotation,  the  apparatus  including  at least one sensor adjacent at least one blade position to provide a time signal corresponding to the actual arrival time required  for  a blade  to move  from a predetermined position  to  the  at  least  one  sensor  position,  the aberrations being caused by misalignment or movement of the at least one sensor with respect to a rotating blade.  The method comprises the steps of first calculating an average blade   arrival   time   for   blade   movement   from   the predetermined position to the at least one sensor position, and  then  estimating  sensor  position  relative  to  the predetermined position based on blade velocity and average arrival   time.     Alternatively,  measured  displacements between blade position and sensor position at the average blade  arrival  time may be used to derive a time signal indicative of blade vibration.

Abstract: Abstract of the Disclosure A device for detecting an instantaneous voltage drop of a DC power source, comprises first means for producing a low-level signal having a duration associated with a period of time in which a voltage of the power source remains lower than a predetermined level, and a high-level signal having a duration associated with a period of time in which the voltage of the power source remains higher than the predetermined level. Second means perform a discharging operation based on a first time constant in response to the low-level signal and a charging operation based on a second time constant smaller than the first time constant in response to the high-level signal.  The second means produce a first signal having levels which are individually associated with the charging operation and the discharging operation.   Third means detect when the voltage of the power source has become lower than the predetermined level by comparing the level of the first signal with a reference voltage level.

Abstract: MICROSTRIP ANTENNA SYSTEM WITH   MULTIPLE FREQUENCY ELEMENTS                 ABSTRACT OF THE DISCLOSURE An  antenna  system  includes  an  array  of  microstrip antenna elements wherein each of the elements includes two or more radiators.   Electromagnetic signals are coupled from an input terminal of each element via one or more circulators which allow for application of an input signal to a first of the radiators followed by rerouting of respective signals to the next radiator. The radiators  are tuned to radiate  at  successively higher portions of the electromagnetic spectrum.  By virtue  of reflections of higher frequency radiation from a radiator tuned to a lower portion of the signal spectrum, each radiator radiates only that portion of the signal spectrum falling within the bandwidth of the radiator.  By  using  three  radiators,  each  antenna element is capable of radiating a signal spectrum three times  as  wide  as are  the  bandwidths  of  a  single radiator.  Included within the antenna system is one or more power dividers  to  form one  or more beams  of radiation.   With the use  of plural  power dividers, switching  circuitry  may  be  employed to  select sequentially individual ones of the power dividers so as to scan a beam of radiation.
