Patent CA-2172304-C (CA)
Inventor: GOSTINE MARK L
IPC: A47C20/02
Filed: 1996-03-21
Granted: 2000-04-25
Abstract: A therapeutic pillow for relieving various types of low back pain. The pillow comprises two hemispherical end sections joined by an elongated midsection. The midsection is a substantially flat lumbar support portion with sloping surfaces extending to each end section, to provide a pillow that is substantially concave in shape. In use, when sleeping on one's side, the pillow is placed generally transverse to the length of the body under the side. The midsection provides support and alignment for the lumbar spine, thereby relieving pain associated with sagging of the spine. Further, by placing one hemisphere close to the back or hip, the pillow will wrap around the hip area and place pressure on the sacro-iliac joint, for pain relief in that particular area of the body. The pillow can also be placed transverse to the body under the stomach when one sleeps on his or her stomach, again to support and align the lumbar spine. The hemispherical end pads also serve to confine the sleeping person on the pillow and keep the person from rolling out of the pillow.

Title: Apparatus using memory control tables related to video graphics processing for tv receivers
Inventor: BUTLER DONALD S
IPC: G09G5/38
Filed: 1996-06-24
Granted: 2000-08-29
Abstract: Apparatus for processing mixed video and graphic signals for display on a television receiver includes a Graphics Memory and a Memory Controller and Sprite State Machine. The Graphics Memory includes a Sprite List table, a Sprite Data table, and other optional tables. The Sprite List table lists one or more graphics in a predetermined sequence for display on the television receiver, and stores general information related to the graphics within control words in each listing. The Sprite Data table stores pixel data for horizontal lines of each of the graphics which are accessed by a control word in each of the graphic listings in the Sprite List table. An optional Line Control table contains control words that are accessed via the graphic listing for providing independent controls for each of the horizontal lines obtained from the Sprite Data table to produce predetermined special effects. An optional Span List table is used to determine which of the graphic listings occur on a horizontal line to cause an accessing of only those occurring graphic listings for assembling pixel data for that horizontal line. The Memory Controller and Sprite State Machine accesses the tables of the Graphics Memory in a predetermined sequence in order to assemble and display each of the graphics and their special effects at predetermined locations in the horizontal lines on a screen of the television receiver. The Memory Controller and Sprite State Machine also uses field enable controls from the Sprite List Table for assembling one graphic on lines of a first field and a second graphic on lines of a second field.

Title: Method and apparatus for detecting tube occlusion
Inventor: BLYTHE ROBERT LEWIS
IPC: A61B18/00
Filed: 1998-01-30
Granted: 2000-05-30
Abstract: A method and apparatus (10) detect occlusion in a tube to a passage into a body cavity. An argon gas supply output (13) received by plural selectable flow orifices so one or more of the orifices delivers predetermined metered gas. A duct (16) with a volume of gas selectively provides metered gas to the passage. The tube connects the passage and the duct (16) periodically so a duct (16) pressure transducer (17) can signal. A circuit tests signals of tube equalization with a back pressure. A three way valve controlled by the circuit connects the duct (16) transducer to gas metered to the cavity. The valve alternatively connects the duct (16) transducer to the tube to equalize the tube with metered gas to the back pressure. A monitor (20) of the signals determines the rate of pressure change after the valve connection The monitor (20) indicates pressure equalization after a timed interval with a timer to establish intervals for checking back pressure. The monitor (20) remembers cavity pressure before connecting the duct (16) transducer to the metered gas and compares remembered pressure with the back pressure after each test interval. Plural orifices provide specific gas flows to the handset and the valve for equalizing them with metered gas as a function of the flow. Connecting plural orifices to meter gas output, delivering the metered gas output with one or more of the orifices, containing the volume of gas in the duct (16) connected to the metered gas output, selectively connecting the duct (16) to the passage, connecting the tube to the passage with the duct (16) and the transducer to periodically signal are steps. Coupling the circuit to one or more orifices, equalizing the tube with back pressure in response to the signals and coupling the transducer to the metered gas output are steps. Connecting the duct (16) transducer to the tube permits periodic back pressure equalization with metered gas output, signaling the monitor (20) with the transducer, determining periodically the rate of pressure change in the tube by the transducer, indicating in the interval with the monitor (20) equalized tube pressure and remembering cavity pressure before connecting the metered gas output and the transducer for intervals and providing specific flows to the handset and the valve to make the back pressure a function of the selectable flow are steps.

Abstract: Un système permettant d'appliquer une substance a une structure tridimensionnelle avec une surface avancée et des espaces pour recevoir la substance. La substance s'étend à un niveau en dessous de la surface avancée pour être protégée d'un contact accidentel avec une surface externe. La substance reste protégée jusqu'à ce que la surface tridimensionnelle soit suffisamment déformée pour avoir une structure essentiellement bidimensionnelle pour exposer la substance et lui permettre de venir en contact avec la surface externe sans qu'une déformation de la surface externe ne soit nécessaire. La déformation se fait, de préférence, par une compression au cours de laquelle la surface avancée de la structure tridimensionnelle se déforme dans la direction de la force de compression. Un procédé pour réaliser la structure tridimensionnelle consiste à appliquer un revêtement d'une substance sur une surface de formage, transférer le revêtement de la surface de formage sur un matériau et conférer à ce matériau une structure tridimensionnelle sur la surface de formage pendant que la substance est en contact avec celle-ci.
