Title: Analog to digital and digital to analog signal processors
Inventor: GERDES RICHARD C
IPC: H03M1/14
Filed: 1991-05-14
Abstract: ABSTRACT Improved analog to digital  and digital to analog signal processors are disclosed wherein a quick approximation of the input signal to the signal processor i. attained and a more accurate approximation is later attained for the input signals   For the analog  to  digital  conversion,  a  standard  analog  to  digital converter  having  a   finite  resolution  or  a  predetermined quantization  error  is  used  to  create  part  of the  digital representation.  The remainder of digital representation is created by processing an error signal due to the finite resolution of a standard analog to digital convertor and the infinite resolution of the analog input signal to a delta modulator.   In a digital to analog signal processing circuit, the first part of the digital representation  is  converted by  a  standard  digital' to  analog converter and the remaining portion is integrated into a frequency limited analog signal and then summed to reconstruct the analog signal.    To  avoid  overshoot,  the  integrators  of the  signal processor  are preset based upon the increase or the decrease in the first part.  Further, the rate of integration is controlled so that the rate slows as the digital representation of the analog signal become increasingly more accurate representation of the input signal.

Patent CA-2054875-A1 (CA)
Title: Optical fiber sensor with localized sensing regions
Inventor: DOMASH LAWRENCE H
IPC: G01R33/02
Filed: 1991-11-04
Abstract: ABSTRACT OF THE DISCLOSURE      A coupling mechanism for a non-identical dual core optical fiber.  The fiber is sensitized along selected portions of its length by coating the fiber in a pattern of bands of specified spacing with material that is sensitive to the presence of a predetermined parameter or environmental field.  By virtue of inequality of propagation properties and mismatch of optical phase of the fields of the two cores, evanescent wave coupling is largely or wholly suppressed except in those portions of length coated in the specified spatially periodic manner.  Optical power launched into one of the two cores remains propagating within that core alone over an extended length of the fiber, except for that period of time when the predetermined parameter or environmental field is sensed.  The specific spatial periodicity of the pattern of coating bands on the outside of the fiber acts in concert with the nonidentical propagation parameters of the two cores to effect intercore coupling of optical energy.  This coupling, representing sensitivity to any environmental field which causes strain in the coating, is effective only on those portions of the dual core fiber length which bear a specific coating pattern.

Abstract: Abstract For the  existing ways of  timer recording television  programs by video  cassette recorders,  the users  have to  have a  good understanding  of the  process  of setting  the timer  which is usually a  headache for many  people. In  this invention, users could  do this much easier (or  with a new method by searching through  the  program  schedules  transmitted  by  TV  stations through air  or  cable  along  with  the TV  signal  which  are memorized  by  this newly  invented  equipment.  Viewers  could retrieve this memorized program  schedules to set the timer for recording.   This  invention   is  a   different  approach  and improvement to another  new method of setting timer  recording, which had been granted  the patent by USA, by  assigning a code to each program; viewer could just  press a two or three  digit code to set the timer for the VCR recording.            Another  feature  of  this  equipment  is   that  this  program schedules could  be retrieved  any time  by  the users  through buttons on  TV receivers, VCRs or  their remote control  units, this compares to the existing program schedules being  shown on separate TV  channels, and information  of programs could  only appears  consecutively,  viewers  have  to  wait  to  see  what programs are available.            The other feature of  this equipment  is that it could  perform an instant timer recording  feature during a program (eg. great movie) is  being promoted by TV station. If the viewers like to record this great movie,  they can  simply press one button  to set the  timer during  this great  movie is  being promoted  by it's own  channel through the screen. This serve a simplest way of setting timer recording and is not existing on the market.            This equipment could serve  to memorize other  data which could be retrieved by the users any time they want to.

The tube includes a forward end having a dispensing orifice and a rear end through which the tube may be filled with solder paste.  After the tube is filled with solder paste the rear end is sealed with a plug manufactured from the same material as which the tube is manufactured. Solder paste is dispensed from the tube by applying pressure to the plug to pushthe plug through the body of the tube, thereby causing solder paste to be squeezed out of the orifice.  The tube may be disposed of by melting in a solderpot so that the melted material which comprised the tube may form one of the constituent elements of new solder being manufactured.
