Abstract: DRIVER CIRCUIT                            ABSTRACT      A driver circuit for applying a first signal having a desired have form, frequency and peak to peak voltage to a coaxial transmission line which also has applied to it a second signal having a substantially higher frequency.     An operational amplifier has the first signal applied to its noninverting input terminal. The output of the operational amplifier is applied across the primary winding of a driver coupling transformer through an inductor which provides high impedence to the second signal. The voltages induced in the secondary winding of the driver transformer are applied to the transmission line. The primary winding of a feedback transformer is connected in parallel with the secondary winding of the driver transformer.          The voltage induced in the secondary winding in the feedback transformer are applied by a feedback circuit including an R.C. filter to the inverting input terminal of the operational amplifier. The signal applied to the invrting input terminal includes both an A.C. component and a D. C. component,  which components cause the output current of the operational amplifier to induce in the secondary winding of the driver transformer a signal, the wave form, frequency and peak to peak voltage of which substantially equal those of the first signal applied to the noninverting input terminal the operational amplifier.

Abstract: ABSTRACT                 Temperature Measurement Temperature is measured by launching pulses of light into an elongate optical fibre and determining the temperature at positions along the fibre from the intensity of light scattered at those positions.  The input pulses can have either the same or two different wavelengths, and the scattered light can be either Raman or Brillouin scattered and either forward scattered or backscattered.  One position along the fibre can be maintained at a known temperature in order to provide a reference for other calculations.  In particular embodiments the temperature is derived from the ratio between the intensities at two anti-Stokes wavenumber shifts or between an anti-Stokes scattered and a Rayleigh scattered intensity measurement.  Otherwise the intensities of Stokes and anti-Stokes shifted Brillouin back scattered light can be used to derive the temperature.

Abstract: STANF.56A                COHERENT DISTRIBUTED SENSOR AND METHOD  USING SHORT COHERENCE LENGTH SOURCES      Abstract of the Disclosure A  distributed  sensor  system  including  an  optical source  having  a  short  coherence  length  for  optionally continuously monitoring each sensor in the system.  In one preferred embodiment, an array of fiber-optic sensors are organized  in  a  ladder  configuration,  with the  sensors positioned  in spaced relation and defining the rungs of the  ladder.   Light  transmitted  through  the  sensors is multiplexed onto a return arm of the ladder, with sensor spacing being such that interference between light from different sensors is prevented.   The multiplexed signals are received by an optical fiber receiver which couples the  multiplexed   light  with  an   interfering  optical reference  signal  to  produce  a  phase  difference signal representing  conditions  influencing  selected  sensors. Embodiments  are  disclosed  for  use of either pulsed or continuous  wave light  sources.    In  another  preferred embodiment,  the  sensors  comprise  a plurality  of Mach-Zehnder interferometers connected in series configuration by  a  common  optical  fiber,  which  provides  multiplexed output signals from the sensors to a plurality of Mach-Zehnder interferometers comprising receivers.  The optical path length differences between the arms of each of the sensors are selected to prevent interference between the multiplexed  sensor output  signals  from various sensors. The optical path lengths through the sensors and receivers are  structured  so  that  each  receiver produces a phase difference signal relating to conditions affecting light transmission  through  a  specific  sensor.    A  phase  and amplitude modulation technique is disclosed for providing heterodyned  output  signals  from  the  distributed  sensor system.

Abstract: Abstract of the Disclosure An improvement to a disk file servo control system removes repeatable error from the read/write head position error signal (PES) during track following.  The disk file includes a microprocessor 60 and associated memory devices 62, 64.  A table of values of a sine function having a frequency equal to the disk rotational frequency is stored in a memory device.  The microprocessor 60 receives each sample of PES from the servo control system and values from the sine function table in the memory device and computes a group of tap weights, each tap weight being a function of the PES sample, the value of a sine or cosine function with a frequency at one of the harmonics of the disk rotational frequency, a learning rate factor and the corresponding value of the tap weight for the previous PES sample.  For each PES sample, the tap weights in a group are added to generate a repeatable error correction signal Uc which is summed with the control signal U to the head actuator, thereby generating a modified control signal Um which causes the head to follow the true track centerline.  The repeatable error components are thus removed from the PES.
