Abstract: STRUCTURES REINFORCED BY A HEAT-INDICATING                    COMPOSITE MATERIAL                 ABSTRACT OF THE DISCLOSURE     Structures, such as pressure vessels or pipes, for the storage and transportation of fluids under pressure are wrapped with a composite material  including a high-strength unidirectional filament material in a matrix of a flexibilized isophthalic polyester resin which has an elongation at least equal to the elongation of the material of the structure.  The index of refraction of the resin is matched to the index of refraction of the filament material so that the pressure vessel is visible through the wrapping.   The resin discolors when exposed to a heat above which the material of the structure weakens, thus acting as an indicator that the structure is unsuitable for use.

Title: Rate-responsive pacemaker
Inventor: WEBB STUART C
IPC: A61N1/372
Filed: 1989-02-17
Granted: 1993-09-07
Abstract: ABSTRACT            RATE-RESPONSIVE PACEMAKER     A pacemaker has means for producing first  and  second signals  one  of  which changes rapidly in response to changes  in  exercise  level  but   may   inaccurately represent  the  appropriate  pacing rate.  Such signal may be derived from a vibration  sensor.   The  second signal  accurately represents the required pacing rate but changes slowly in response to exercise  level  and may   represent   any   of   a   number  of  different physiological variables,  such  as  respiratory  rate. The  signals  may be derived from the same or separate sensors.  A control circuit  provides  a  pacing  rate appropriate  to resting conditions if the first signal has a value less than a threshold  regardless  of  the value  of  the  second  signal.   The  pacing  rate is elevated  to  a  predetermined  level,  such   as   95 beats/min,  if  the first signal exceeds the threshold but the second signal has  a  value  indicative  of  a pacing  rate  less  than the predetermined level.  The pacing rate is further elevated to substantially equal that  indicated by the value of the second signal when the first signal exceeds the threshold and the  second signal  indicates a rate higher than the predetermined rate.

Abstract: Abstract of the Disclosure An ignition system for an internal combustion engine, such as an outboard marine engine,  which  includes an advanced timing schedule, a normal timing schedule, and a circuit  for  switching  between  the  two  schedules  or disabling  both  schedules  based  upon  engine  operating conditions.    The  ignition  system  includes  an  opto-electronic time base generator which produces two sets of timing pulses relative to crankshaft position which are normal timing pulses and advanced timing pulses.  The time base generator comprises a LED-phototransistor pair and an encoder disk attached to the crankshaft with slots to interrupt the emission path between LED-phototransistor pair.   The normal pulses are generated based upon the trailing edge of each slot while the advanced pulses are generated based up the leading edge, wherein the width of the  slots  indicate the degree  of  advancement  of  the advanced schedule over the normal schedule.  Both schedules are inhibited based on a high overspeed condition and a low overspeed condition when the engine is overheated, wherein there is a smooth transition between the two conditions.

Abstract: ABSTRACT         A digital wireless subscriber telephone unit for wireless connection with a base station.  The subscriber unit has a baseband processor which is coupled to storage means for the baseband functions.  The baseband processor is direct access  coupled  to  a  modem  processor  whereby  the  two processors may communicate with each other.   The modem processor generally  acts  as  the master  in the  system, although lock-out means may be used in certain circumstances. The signal from the modem processor is converted to an analog signal, which is subjected to deglitching, and the deglitched signal is then upconverted and filtered to form an IF signal which is thereafter amplified.  The amplified IF signal is combined with a signal generated by a synthesizer to provide an RF signal.  on the basis of certain signals received from the base station, the baseband processor produces initiating signals which determine whether the subscriber unit will be in the transmit mode or the receive mode.   In intervals between actuation of the system, a training mode is used wherein a known signal from the modem processor is compared with looped-back signal to produce correction constants to compensate  for undesirable variations  in  the  IF,  these constants being stored for use in correcting actual received signals.  During demodulation, the modulated digital signals are  fed  to  the  modem  processor  in  the  form  of  time multiplexed I and Q samples and are demultiplexed.   The demultiplexed I and Q samples are fed to an equalizer and frequency correction circuit for minimization of errors and for production of a frequency correction signal which is used to correct any errors in the timing of the system and in the output of the synthesizer.
