Patent CA-2088925-C (CA)
Title: Linear film scanner operable at different line rates
Inventor: LEES ROGER T
IPC: H04N9/093
Filed: 1992-06-08
Granted: 1995-12-12
Abstract: A film scanner operable according to dual line standards includes red, green, and blue linear array sensors (36r, 36g, 36b) separated by a line spacing that constitutes substantially integral first and second multiples of the line spacings of the respective line standards. More particularly, in 1125 and 1250 line television standards, the linear arrays are spaced such that the distance is substantially equivalent to 9 lines of the 1125 line standard and 10 lines of the 1250 line standard. The output signal from each linear array is registered to the same line for each standard by inserting separable sets of line delays (52a, 52b, 53a, 53b) into the signal paths from two of the linear arrays. The separable delays correspond to the first and second multiples of the respective standards. By enabling a switch (54a, 54b) to switch between the respective sets of delays, an output signal is developped for a selected line standard.

Title: System and method for dynamically varying between interrupt and polling to service requests of computer peripherals
Inventor: HOFFMAN HARRELL
IPC: G06F9/48
Filed: 1993-08-27
Granted: 1999-11-09
Abstract: A system and method for managing service requests from peripherals connected to a personal computer or workstation by operating both in an interrupt mode and a polling mode, with selective transition therebetween. In one practice of the invention, peripheral device service requests are first managed on an interrupt basis, then transition to a polling mode when the interrupt rate exceeds a rate threshold, and subsequently revert back to the interrupt mode when the rate again decreases below a threshold. The transition is dynamic and situation adjustable by parameter selection both as to the number of service requests and as to the time interval used to initiate transition between the interrupt and polling modes.

IPC: A63B61/00
Filed: 1994-01-14
Granted: 1999-02-02
Abstract: A monitor system which combines manual and electronic operations is proposed as a method to identify and correct line-call errors which occur in the conventional line-call system used in the game of tennis.  The monitor system enables several persons seated in various locations in the stands to act as line-call monitors by identifying obvious or gross line-call errors committed by line judges.  The monitors communicate with the chair umpire by means of small hand held "call-box" transmitters each equipped with a push button which is pressed when the monitor detects a clear mistake by the line judge.  The chair umpire wears a small radio receiver unit which accumulates the separate or simultaneous decisions of the monitors and generates a short "beep" sound in a speaker or an external earphone if certain simple criteria are met.  The umpire can then make the appropriate overrule to correct the line-call error.

Title: Seamless basketball
Inventor: MEYER DARIN J
IPC: A63B41/08
Filed: 1994-05-09
Granted: 1997-11-25
Abstract: A basketball having a surface devoid of lines, seams stitching or other markings that span the circumference of the ball for  forming  a  uniform  and  continuous  surface.  The  seamless basketball has a uniform stippling along its entire surface and integrally a part thereof and may have a logo printed thereon. The ball  is  formed  from  a  molded  outer  cover  formed  from  two hemispheres having an inflatable bladder positioned therein. The inflation valve is hidden from view under the cover or, if exposed, is flush with the cover and of the same color as the cover. The lack  of  seams,  stitching  or  other  markings  spanning  the circumference of the outer surface of the ball causes the ball to have no particular orientation. Therefore, the user of the seamless basketball is not inclined to align the ball in a particular fashion prior to shooting the same.  As  such,  wasted time is eliminated and a quicker release and greater concentration is gained. Additionally, the ball is subject to a truer bounce because of the more uniform spherical nature of the same.

Title: High efficiency fuel-fired condensing furnace having a compact heat exchanger system
Inventor: LU LIN-TAO
IPC: F24H3/08
Filed: 1994-07-13
Granted: 1997-07-08
Abstract: A tubular recuperative heat exchanger structure is mounted in a housing chamber within a fuel-fired condensing furnace in the vertical flow path of supply air being flowed through the housing by a blower.  The heat exchanger structure comprises a primary heat exchanger defined by a vertically serpentined series of combustor tubes into open inlet ends of which a series of inshot-type fuel burners flow flames and hot combustion gases, and a secondary heat exchanger formed from a horizontally extending series of finned heat exchanger tubes having inlets in flow communication with the outlets of the combustor tubes and outlets in flow communication with the inlet of a draft inducer fan.  The firing rate of the furnace is correlated to the configuration and relative geometries of the primary and secondary heat exchanger tubes in a manner making the overall heat exchanger highly compact and thermally efficient in addition to reducing air blower and draft inducer electrical consumption as well as reducing the operating noise of the furnace.

Abstract: A tactile  feedback  switch  actuator  (12)  for  an associated force-actuated switch (52) has a key cap (22) linked to a collapsible dome (34)  by an optical fiber (36), all of which are light-transmittable.  The actuator (12) is operated by manually applying an actuating force to the key cap (22) which exceeds the modulus of collapse of the dome (34).  In response, the dome (34) reversibly collapses  in  a  tactile  snapping  action  against  the underlying light-transmittable switch panel (54) having pressure-sensitive contacts (62a, 62b) embedded therein to change the operative state of the switch (52).  When the actuating force is withdrawn, the collapsible dome (34)  elastically returns to its uncollapsed condition, while  the  switch  (52)  remains  in  its  newly-actuated operative state.  The actuator (12) and associated switch (52)  are structurally integrated and aligned so that light-emitting   pixels    (60)    in   an underlying electroluminescent panel provide visual feedback of the operative state of the switch (52).

Patent CA-2163937-C (CA)
Inventor: SCHELLINGER MICHAEL JOHN
IPC: H04B7/26
Filed: 1995-11-28
Granted: 2000-02-08
Abstract: A unique method improves channel scanning by reducing the time required to scan channels. The method reduces the number of channels which must be scanned using information previously obtained in a scan. If two sets of channels which overlap are scanned in two separate scanning steps (522), information obtained in a first channel scan can be used, thereby eliminating the time required for a second channel scan. For example, if the dedicated control channels and the paging channels of a cellular telephone system overlap, the channels which overlap need not be scanned during the channel scan of the paging channels. The method further reduces scanning time by ending the channel scanning of a particular channel if an undesired channel type is detected (808).

Abstract: A QPSK demodulator that can be made smaller in size and lower in cost by restricting a storage capacity needed for a TAN-1 ROM to a minimum. Values of I and Q channel base band signals obtained by converting and quantizing a received signal is approximated to a nearest one of values on (2N-3 + 1) segment lines represented by Q=(n/2N-3)I, where n=0, 1, ..., 2N-3, with a phase accuracy of positive N bits.  Data corresponding to the approximated segment line is previously stored in a TAN-1 ROM as phase arithmetic data.  An address decoder converts each base band signal into an address.  An arithmetic circuit obtains phase data, for obtaining a QPSK demodulated signal, by performing a predetermined arithmetic operation, which is commensurate with the size of I and Q channel base band signals, on phase arithmetic data stored in the TAN-1 ROM in association with the converted address.
