Title: Apparatus for removing corneal tissue with infrared laser radiation
Inventor: TELFAR WILLIAM B
IPC: A61F9/008
Filed: 1996-09-17
Abstract: A surgical technique for removing corneal tissue with scanned infrared radiation is disclosed which utilizes short mid-infrared laser pulses to provide a tissue removal mechanism based on photospallation.  Photospallation is a photomechanical ablation mechanism which results from the absorption of incident radiation by the corneal tissue.  Since photospallation is a mechanical ablation process, very little heat is generated in the unablated adjacent tissue.  The disclosed surgical system includes a scanning beam delivery system which allows uniform irradiation of the treatment region and utilizes low energy outputs to achieve controlled tissue removal.  A real-time servo-controlled dynamic eye tracker, based on a multiple-detector arrangement, is also disclosed which senses the motion of the eye and provides signals that are proportional to the errors in the lateral alignment of the eye relative to the axis of the laser beam.  Temporal and frequency discrimination are preferably utilized to distinguish the tracking illumination from the ambient illumination and the surgical laser beam.

Abstract: Allophanate-modified 1,3-phenylene diisocyanates or 1,1-biphenyl diisocyanates or 1,1'-oxy-bis-(isocyanato benzenes) which are storage stable liquid at 25°C are made by reacting the diisocyanate and a mono-alcohol to form an isocyanate containing urethane groups.  The urethane groups in the diisocyanate are then converted to allophanate groups. The resultant product which has an isocyanate group content of from about 10 to about 40% may be further reacted with isocyanate-reactive compounds to produce an allophanate-modified diisocyanate prepolymer containing urethane or urea groups having an isocyanate group content of from about 5 to about 40.0%.  The liquid, storage-stable, allophanate-modified diisocyanates produced by these processes are particularly useful in the production of elastomers and flexible foams.

IPC: H03C7/02
Filed: 1997-04-11
Abstract: A direct QAM modulator for generating a high power  QAM  modulated  signal  at  microwave  frequencies comprises a hybrid to create the required RF signals for I and Q paths.  In each path, a rat-race coupler is used to get  the  in  phase  and  out  of  phase  RF  signal.    The subsequent circuit blocks in each path consist of a single pole double throw switch (SPDT) switched by the polarity of the incoming data, a reflection attenuator, implemented by using forward biased pin diode terminations and controlled by the absolute values of the baseband pulse amplitude modulation (PAM) signal, and a variable reflection phase shifter  to  adjust  for  the  phase  error.    To  realize modulated  signal  filtering  and  to  compensate  for  the nonlinearities, a combined prefiltering and predistortion block is used to shape the baseband PAM signal in each path.  Finally, a power combiner is used to combine signals from the two paths into one high power QAM modulated and filtered output signal at microwave frequency.
