Title: A flexible interface to authentication services in a distributed data processing system
Inventor: LOUCKS LARRY K
IPC: G06F1/00
Filed: 1990-05-07
Abstract: In  a  distributed  data  processing  system,  the authentication of a process at one node for the use of a service at another node is performed in a facility that is separate from the requestor and service process.  The separate facility is also replaceable,  thereby allowing different  authentication  policies  to  be  implemented within  the  distributed  data  processing  system. The requesting process and the service process merely pass the authentication information between themselves without attempting  to  interpret  the  work  of  the  separate authentication facility.   In addition to authenticating the  requestor  to  the  service,  the  service  is  also authenticated to the requestor.

Patent CA-2039780-A1 (CA)
Inventor: RODRIGUEZ-CAVAZOS ENRIQUE
IPC: H04N3/23
Filed: 1991-04-04
Abstract: A circuit provides North-South pincushion correction and gullwing compensation in a raster display of a television apparatus. A correction circuit generates a generally parabolic, horizontal rate correction signal to correct for North-South pincushion distortion. A gullwing compensation circuit is coupled to the correction circuit and forms a feedback path therein for amplitude modifying the correction signal to further correct for gullwing distortion. The gullwing compensation circuit amplitude modifies the generally parabolic signal as a function of itself, achieving an equilibrium condition. A vertical deflection circuit drives a vertical deflection coil with the gullwing compensated correction signal. The correction circuit comprises a ramp waveform generator having a controllable current source generating a constant component of current for pincushion correction and a variable component of current responsive to the feedback signal for gullwing compensation. The variable component of current varies inversely to the feedback signal, which is coupled in the feedback path to the controllable current source through an inverting amplifier. The output of the inverting amplifier modulates the current supply to modify the resulting shape of the parabolic signal to compensate for gullwing distortion by increasing the slope of the parabola on both lateral sides.

Patent CA-2042186-A1 (CA)
Inventor: SCHANEN PAUL C
IPC: H03M1/18
Filed: 1991-05-09
Abstract: An autozeroing apparatus is disclosed for correcting the offset error in a computerized axial tomography (CAT) scanner data acquisition subsystem (DAS) . The DAS includes a floating point amplifier for applying discrete amplification factors, or gain range segments, to an analog input before conversion to digital in an A/D converter. A digital autozero circuit is connected to the output of the A/D converter and adds a digital offset value to each A/D converter sample during data acquisition to correct for the net offset errors throughout the DAS. Separate storage latches are included for storing offset values corresponding to each gain range segment, and the offset value used for each sample correction corresponds to the gain range segment used for that sample. During an autozero reference interval, a reference voltage is applied to the DAS and the offset values are updated so as to force the corrected A/D converter output to agree with the reference voltage.

Title: Pregnancy specific proteins applications
Inventor: CHAN WAI-YEE
IPC: C12N5/02
Filed: 1990-01-11
Abstract: ABSTRACT      At least seven genes have been identified which encode proteins generally identified as pregnancy specific protein (SP1), also known as pregnancy specific beta glycoprotein (PSBG).  These genes have been found using human placental SP1 labelled cDNA in a number of mammalian species, including human, baboon, cow, sheep, goat, pig and rat, and non-mammalian species, including fish and bird.  The genes are classified on the basis of their nucleotide sequence, structure, glycosylation sites, restriction enzyme mapping, and tissue of origin.  Genes have been found in cells of human placenta origin (three groups); in intestinal cells; in cells of both testis and placental origin; in tissue of testis origin; and in HeLa cells.  One clone encodes a SP1-like protein which is specifically found in placenta and appears to have a hydrophobic C-terminal region, indicating that it is membrane bound.  These cDNAs are at least 65% homologous with some members of the immunoglobulin gene superfamily such as CEA.  Methods for making and using the DNA sequences, proteins, and antibodies to the proteins are also described, particularly for diagnostic work.          Immunosuppressive activity and growth promoting activities have also been demonstrated by suppression of lymphocyte proliferation and inducement of megakaryocytopoiesis, respectively.

Filed: 1991-09-11
Abstract: UNIVERSAL ELECTRONIC BALLAST SYSTEM   ABSTRACT    A universal electronic ballast system (10) is provided for actuating at least one gas discharge lamp (1900) having any one of a plurality of predetermined wattage ratings.          Electronic ballast system (10) includes a filter circuit coupled to an AC power mains (100,110) for substantially suppressing spurious signals passing into or from the power source.  The filter circuit is coupled to a regulated switching power supply circuit (14) which generates a regulated boost voltage and draws a substantially constant in phase sinusoidal load current from the power source supplied to a switching circuit (16) which generates a regulated pulsating current at a predetermined frequency.  Responsive to the regulated pulsating current a high voltage is induced in the primary windings (1710 and 1680) of induction transformer (T3).  The high voltage is coupled to gas discharge lamp (1900) by means of the magnetic coupling between primary winding (1730) and secondary winding (1770) of the output transformer (T2).  Universal electronic ballast system (10) monitors the presence of gas discharge lamp (1900) by means of the voltage divider (1270,1830) and protection circuit formed by diode (1490), transistors (1380) and transistors (1380 and 1440), for maintaining the switching transistor (1590) in an "off" condition by shunting the base drive signal therefrom responsive to gas discharge lamp (1900) being removed from ballast system (10).
