Patent CA-2000007-A1 (CA)
IPC: H04L27/227
Filed: 1989-10-02
Abstract: A  demodulator  mechanism  which  uses estimates of the   in-phase   and   quadrature-phase   components  or differential   phase   modulated   carrier  signals  for performing a coherent demodulation  of these  signals is described.   The instantaneous  estimates, obtained from an  estimator  circuit,  are  fed  into  a  differential carrier recovery  circuit, which provides for a feedback of ideal sine and  cosine components,  and combined with the instantaneous estimates for incrementally decreasing a  phase  error  signal  generated  in  a  computational circuit.    By  thus  incrementally decreasing the phase error  signal,  an  ideal  phase  angle   is  eventually obtained,  thereby  providing  for  coherent demodulated output components of the input carrier signals.

Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed herein is an automotive seat which includes a seat frame and a plurality of S-springs which are spanned between spaced two portions of the seat frame.  Each spring has one U-shaped end portion. In order to tightly and unmovably connect the U-shaped end portion of each spring to selected one of the side portions of the frame, an improved spring holding structure is formed on the selected portion of the frame, which includes a tunnel portion which is integrally formed on the selected portion and two raised portions which are integrally formed on the same selected portion in a manner to put therebetween the tunnel portion.  The distance between the two raised portions is substantially equal to the longitudinal length of the U-shaped end portion of the spring.  The U-shaped end portion of the spring is received in the tunnel portion having its longitudinal ends respectively contacting with the two raised portions.

Abstract: ABSTRACT             Monoclonal antibodies which specifically bind to the amino acid sequence ALA PRO ASP THR ARG of the repeat sequence of human polymorphic epithelial mucin.  The antibodies can be used to detect mucin in biological fluids, and thus can be used to detect adenocarcinomas which are characterised by high levels of mucin production.  Peptides which correspond in amino acid sequence to the epitope recognised by the monoclonal antibodies may be used as therapeutic agents in vaccines for the treatment of adenocarcinoma.

Abstract: IMPROVED EATING FORK                     ABSTRACT OF THE DISCLOSURE    An improved eating fork having a conventional handle,  an extended flat body portion and a plurality of short conical tines each having a small smoothly rounded end.  The short tines project along parallel axes from the forward end of the flat body portion extending from the fork's handle.  The body portion has a width slightly  greater  than  the  distance  across  the  bases  of  the plurality of tines.  The flat body portion of the improved fork contains in its upper surface a generally rectangular depression.          The tines have a length about one fifth the length of the fork's flat body portion.  The surfaces which join the tines to the flat body portion are all curved and all surfaces of the fork are polished during manufacture of the fork.  This fork eliminates the u-shaped areas between the tines, thus eliminating surfaces which offer areas for attachment of dirt, grease and other unsanitary material, which can become breeding grounds for bacteria and other disease carrying organisms.

Abstract: PARKING LAMP OPERATING SYSTEM                ABSTRACT OF THE DISCLOSURE    A parking lamp operating system reduces the electrical load on the battery of a vehicle, such as a truck, during periods when the vehicle engine is off but the parking lamps of the vehicle remain on wherein a switched signal  input from the battery  is modulated to provide a pulse-width-modulated output to the gate of a power transistor having a power input from the battery and an output to the parking lamps.   The  pulsed  signal   causes  the  transistor to intermittently  switch  the  power  to  the  lamps  thereby reducing  the  effective  voltage  thereto  while  providing sufficient light output to be observed. The modulator may be bypassed by a second signal line connected to the vehicle alternator to provide a continuous signal to the transistor gate,  thereby providing full power to the lamps when the engine is running.

Abstract: An  adjustable  bent  housing consisting  of  an  inner housing telescopically received within an outer housing.  A sleeve is provided having an angularly offset clutch face. Spline non-rotatably couple an interior surface of the sleeve with an exterior surface of the inner housing.  The sleeve is axially slidable along the exterior surface of the inner housing between an inoperative position wherein the sleeve is spaced from the outer housing and an operative position.  In the operative position the angularly offset clutch face of the sleeve engages an angularly offset clutch face on the outer  housing  thereby  non-rotatably  coupling  the  inner housing  and  the  outer  housing  in  a  bent position  the magnitude of which is dependent upon the relative rotational positioning of the outer housing and the inner housing.  A first  annular  member,  having  a  concave  radiused  contact surface, projects from the exterior surface at the first end of the inner housing.   A second annular member having a convex contact surface projects from the interior surface at the second end of the outer housing.
