Patent CA-2009286-A1 (CA)
Inventor: SMYTH WILLIAM K
IPC: H04N1/46
Filed: 1990-02-05
Abstract: An imaging system for producing multicolor images of a scanned subject includes a plurality of detector assemblies. Each of the detector assemblies is sensitive to a specific color. Typically, red, green, and blue detector assemblies are employed for converting images in the primary colors to the desired output image. Each detector assembly includes multiple rows of CCD detector elements positioned in registration with each other for a two-dimensional array of the detectors. Pixels of the subject are viewed repetitively by the successive detectors of the column to provide for an integrated detector signal.      The number of detector elements in each column is varied in accordance with the color sensed by each assembly to provide for greater integration of low-intensity portions of the spectrum. This compensates the output image for variations in filter attenuation, lamp illumination, and CCD sensitivity as a function of light wavelength. The mode of compensation preserves a high signal-to-noise ratio.

Abstract: ABSTRACT OF THE DISCLOSURE   A zero separation force electrical connector which utilizes resilient energy developed and stored during mating to demate the mated contacts and separate the connector with zero separation force.   In  one  embodiment,  the  contacts  of first  and  second housing members are mated in combination to provide the stored resilient energy for subsequent demating of the contacts and the respective housing members with zero separation force.  The first housing member includes male contacts with tapered ends and the second  housing  member  includes  female  contacts  with  spring fingers.  A securing mechanism is utilized to mate the first and second housing members in combination.  During mating the tapered ends of the male contacts coact with corresponding spring fingers of the female contacts, biasing the fingers outwardly,  to store resilient  energy  therein.   Releasing  the  securing  mechanism causes the resilient energy in the spring fingers to be exerted against  the  tapered  ends  of  the male  contacts  to  demate  the contacts and separate the first and second housing members with zero  separation  force.   In  another  embodiment,  the  electrical connector consists of a single housing member containing female contacts with spring fingers and a securing mechanism which is mated  in  combination  with  the  male  pin  grid  array  of  an electronic device such as a printed circuit board.

Patent CA-2022277-A1 (CA)
Inventor: BERTIGER BARY R
IPC: H04W24/10
Filed: 1990-07-30
Abstract: L'invention est une méthode de prévision des transferts de communications entre les cellules d'abonnés mobiles pour les systèmes de téléphonie à satellites. Chaque satellite d'une constellation projette un certain nombre de faisceaux ou de cellules sur la Terre pour les communications avec les abonnés mobiles. Le satellite transfère les liaisons de communication d'une cellule à l'autre au cours de son déplacement au-dessus de l'abonné mobile. Étant donné que le mouvement du satellite est stabilisé dans trois directions, la projection des faisceaux ou des cellules suit un trajet prévisible à la surface de la Terre. Chaque satellite se déplace dans une direction précise par rapport à la Terre. Quand un abonné a été localisé dans une cellule particulière, la cellule suivante dans laquelle la communication de l'abonné sera transférée peut être déterminée à partir de l'emplacement géographique. Pour les abonnés mobiles qui sont à proximité des frontières entre les cellules, d'autres données de localisation peuvent être obtenues par le calcul des taux d'erreur sur les bits. Les résultats de ces calculs permettent de déterminer dans laquelle des cellules sera effectué le transfert de la communication de l'abonné mobile.

Filed: 1990-12-21
Abstract: A   process   for   producing   PTC   (positive temperature  coefficient)   self-resetting   overcurrent protection  elements  using  two  different  crystalline polymers with an organic peroxide and carbon black.  The mixture is kneaded at an elevated temperature.  The two crystalline polymers  include different proportions  of tertiary hydrogen atoms to carbon atoms,  so that the desired  PTC  characteristics  of  a  highly  crystallized polymer can obtain the benefit of greater proportions of tertiary hydrogen in a less highly crystallized polymer. A high degree of grafting to carbon black that increases the number of polymer radicals in the crystalline polymer mixture through the decomposition of organic peroxide. The resulting mixture tends to disperse the carbon black uniformly  throughout  the  resulting  mixture,  and  to position the carbon black in a three-dimensional matrix in which  it  is  fixed  by  cross-linking.    The  uniform distribution of the carbon black reduces localized heating and thus minimizes resistance changes following repeated overcurrent conditions.
