Filed: 1997-10-03

Title: Method of operating the channel equalizer in a receiver for dtv signals subject to co-channel ntsc interference
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1998-09-18
Abstract: A DTV signal receiver includes an adaptive channel equalization filter, a comb filter (20) for suppressing artifacts of co-channel NTSC interference, and an intersymbol-interference suppression filter (26) compensating for the intersymbol interference introduced by the comb filter (20). The adaptation of the equalization filter coefficients is done so as to be insensitive to the presence or absence of the artifacts of co-channel NTSC interference. This avoids the channel equalization filter attempting to compensate for the intersymbol interference introduced by the comb filter (20), which compensation could not be fully accomplished and would make the intersymbol interference in the comb filter (20) unpredictable. The adaptation of the equalization filter coefficients is done so as not to affect the intersymbol interference introduced by the comb filter (20). Consequently, the intersymbol interference can be properly compensated for by the intersymbol-interference suppression filter (26).

Title: Fertility monitoring method
Inventor: ZHANG ZHI GANG
IPC: G01N33/76
Filed: 1994-06-24
Abstract: A method of monitoring the status of a current ovulation cycle of an individual female mammalian (generally human) subject, involving repeated testing of the body fluid concentration of at least one analyte, preferably estrone-3-glucuronide (E3G) of significance in relation to the status of the ovulation cycle, during at lest the pre-ovulation phase of the current ovulation cycle of the individual subject, wherein testing for said analyte concentration during the current ovulation cycle conducted at least once during the interval spanning days 1 to 7 inclusive following the onset of menses, to establish a reference concentration value for analyte in the current cycle, and then testing is conducted repeatedly during a plurality of days, preferably commencing at least 5 numerical days in advance of the mean numerical day on which actual ovulation has occurred over one or more previous ovulation cycles in the same individual subject, analyte concentration values obtained during said repeated testing being compared with the reference concentration value to determine whether a concentration change indicative of imminent ovulation is occurring or has occurred since the previous test. The method can be based solely on E3G measurements.
Patent CA-2274626-A1 (CA)
Title: Method and apparatus for adjusting multiple projected raster images
Inventor: INOVA PETER J
IPC: H04N9/12
Filed: 1997-12-10
Abstract: A three-dimensional smoothing factors lookup table (40) provides detailed control over the full two-dimensional space of a composite image composed of multiple projected raster images. The overall displayed image is improved by adjusting the brightness, gamma (26), and contrast (28) of individual detail elements of the image according to predetermined smoothing factors. A set of smoothing factors (40) is generated by measuring the reflective brightness (24) of detail elements of the projected image to produce a reflective brightness contour map and mathematically inverting the contour map to produce an inverse map. The inverse map (334) is used as smoothing factors to match the colors output by various projectors (16-18) in an arrayed projection system (10). The three dimensional smoothing factors lookup table also enables performance of additional image improvement functions, including projector shading (2), color shift correction, correction of optical vignetting, and automatic edge definition.

Title: Refrigerant fluid injection device and procedure for use with a product mixing apparatus
Inventor: CLOAREC ALAIN
IPC: B01F29/60
Filed: 1999-08-03
Abstract: Typically the mixer has a conical end section closed by a removable cover (14) with a central entry conduit for cooked ingredients. These are frozen separately, or coated in sauce and simultaneously frozen. The refrigerant fluid, e.g. liquid nitrogen, is fed in by an injector nozzle (24), with a vacuum connector (44) for air removal, adjacent to the conduit entry. The delivery pipe (20) includes a flexible hose section, to facilitate cover manipulation, and an elbow (32). Its free end (26), receiving the incoming fluid supply, includes a manually or automatically operated stop valve (28). The pipe includes an electrically controlled interrupter valve (34), opening and closing in synchronism with the mixer's beater to prevent nitrogen impinging on the blades. This valve is placed downstream of a reduced section zone with a calibrated orifice for the expansion of the liquid nitrogen. The elbow (32), downstream of the orifice, effects, through centrifugal forces, a natural separation of the liquid and gaseous phases, creating a liquid stream on the outside of the bend and a gas stream on the inside. A manometer (36) is inserted upstream of the orifice, also a bleed valve (38). To avoid fluid trapping, and facilitate purging, the downstream pipe sections are inclined at e.g. 15 deg. to the horizontal.

Title: Round-trip delay optimization of multiplexed speech channels
Inventor: VALKO ANDRAS
IPC: H04L12/56
Filed: 1998-04-07
Abstract: Data packets are transmitted in forward and backward directions via a multiplexed communications medium, wherein each of the data packets is associated with a corresponding one of a plurality of connections.  Transmission is performed by, for each connection, assigning a forward delay limit and a corresponding backward delay limit, wherein the sum of the forward and backward delay limits is equal to a round-trip delay bound for the connection. The assigned forward delay limits are used to determine the order in which the data packets supplied by the plurality of connections will be transmitted in the forward direction. Similarly, the assigned backward delay limits are used to determine the order in which the data packets supplied by the plurality of connections will be transmitted in the backward direction.  One embodiment accomplishes the forward and backward delay limit assignments by maintaining forward and backward lists of connection identifiers sorted in, for example, ascending order based on time of connection establishment in the forward direction, and in descending order based on time of connection establishment in the backward direction. In another embodiment, transmission order is determined by sorting arriving data packets at the time of their corresponding connection identifiers, wherein the forward and backward sorting rules are selected so that a sum of a forward transmission delay limit and a backward transmission delay limit is less than or equal to a round-trip delay bound for each connection.

Title: Use of compositions containing the combination of acetaminophen, aspirin and caffeine to alleviate the pain and symptoms of migraine
Inventor: KOSLO RANDY J
IPC: A61K31/60
Filed: 1998-06-25
Abstract: The invention provides a safe and economical nonprescription combination of acetaminophen, aspirin and caffeine (APAP/ASA/CAF) for use in treating migraine pain and the cluster of symptoms characteristic of migraine attack, such as nausea, photophobia, phonophobia and functional disabilities. In accordance with the present invention, the use of the APAP/ASA/CAF combination is also effective in aborting the prodrome phase of a migraine attack, prior to the onset of the migraine-associated symptoms, aborting the symptoms of migraine attack prior to the onset of severe, throbbing migraine pain, and aborting migraine pain after a migraine has fully developed. In accordance with the present invention, the efficacy of the APAP/ASA/CAF combination treatment in reducing and eliminating migraine pain is at a parity with the efficacy of sumatriptan, a known, but dissimilar, anti-migraine agent, used at similar dosing regimens. Use of the APAP/ASA/CAF combination composition treatment at the unit dose also advantageously reduces/obviates the need of the migraine sufferer to re-dose or re-medicate at the end of the dosing period in accordance with the present invention.
