Patent CA-2207645-C (CA)
Inventor: NAKAMURA TAKEHIRO
IPC: H04B7/26
Filed: 1997-06-12
Granted: 2001-02-20
Abstract: A method and an apparatus for signal transmission in a CDMA mobile communication system which is capable of preventing an unnecessary increase of an amount of interference power due to the signal transmission through a radio channel and thereby preventing an unnecessary decrease of a system capacity. The radio channel transmission signals are transmitted through the radio channel, where the radio channel transmission signals contain the transmission signals which are formed by control signals or user signals and necessary signals which are necessary in maintaining the radio channel, and this radio channel transmission is controlled so that only signal portions for the necessary signals are transmitted without transmitting any other signal portions when there is no transmission signal to be transmitted.

Abstract: A dynamic patella brace (10) useful for both diagnosis and treatment of patella subluxation, wherein the position of a patella bracing pad (15) is allowed to float to be automatically dynamically repositionable depending upon the amount of flexion and movement of the knee and the amount of tension and pressure applied is provided. The brace (10) includes an elastic sleeve (20) having an aperture (21) for registration and alignment of the knee therein. Additionally, the brace (10) includes a strap assembly (30) to which a plurality of elastic arm members (17, 18, 19) and a patella bracing pad (15) are attached. The strap also includes an anchor which serves to isolate the patella bracing pad from a counterarm member (19) to allow the dynamic repositioning of the pad (15) when the knee is flexed. The patella brace (10) may be used to facilitate positive diagnosis of patella subluxation whose symptoms may mimic other pathological problems of the knee and, therefore, lead to an erroneous diagnosis. The brace (10) may also be used for treatment and/or to delay or avoid the need for corrective surgery.

Abstract: The present invention provides a windshield with a heating arrangement to heat the wiper rest area of the windshield. The windshield includes first and second glass sheets secured together by an interlayer. A single, continuous resistance heating wire is secured between the glass sheets and makes multiple passes through a predetermined portion of the windshield generally corresponding to the wiper rest area such that the wire generates a desired power density within the predetermined portion to heat the wiper rest area. Opposing first and second ends of the wire extend to common connection area along an edge of the windshield and a connector secured to the wire ends provides for external electrical access to the wire. The wire may also extend along a marginal edge portion of the windshield generally corresponding to its A-post area. In one particular embodiment of the invention, an opaque ceramic band is bonded to a major surface of the second glass sheet, which forms the inner ply of the windshield, along its marginal edge portion such that the wire is not visible when the windshield is viewed through the second glass sheet. In addition, the wire may include a coating having a color that generally corresponds to the color of the opaque ceramic band to mask the appearance of the wire when the windshield is viewed through the first glass sheet.

Granted: 2010-04-20
Abstract: An elastomeric member for a tire-building machine, such as an inflatable bead turn-up bladder, center sleeve or bead lock sleeve, includes at least one base layer or sleeve of elastomeric material which terminates in a pair of end members for mounting the sleeve on the tire-building machine. A  plurality of reinforcing cords may be embedded within the sleeve to provide internal reinforcement.

Title: Temperature control system for a multi-compartment refrigerator
Inventor: GILMAN BOBBIE J
IPC: F25D27/00
Filed: 1998-05-22
Granted: 2005-03-22
Abstract: A mechanism for controlling the temperature in and the flow of air between freezer and fresh food compartments in a refrigerator is constituted by a pre-assembled control unit including a housing within which is mounted fresh food and freezer compartment control knobs, a thermostat controller, a temperature sensing capillary tube, a defrost timer, an automatic damper unit for adjusting the opening of an air passageway formed in the housing, and lighting assemblies. The air passageway formed in the housing is adapted to be aligned with an opening leading from the freezer compartment to the fresh food compartment. The capillary tube has one end attached to the thermostatic controller and another end positioned in the air passageway such that the thermostatic controller receives temperature signals from the capillary tube that are associated with not only the temperature of the freezer compartment, but also the temperature of the fresh food compartment. The capillary tube is maintained in the desired position within the air passageway by means of a tube holder. The end of the capillary tube is preferably covered by a sleeve for the thermal dampening purposes. Since the control mechanism is pre-assembled, only a few mechanical connections are required to secure the entire control mechanism within the refrigerator.

Abstract: The present invention finds the overall concentration of a mixture in the following way.  It measures the measurement sensitivity of substance C, of which the constituent composition varies, out of multiple substances A, B and C using sensitivity measuring microwave type concentration meter 17.  It then inputs this measurement result to calibration curve gradient setter 20.  It then finds the calibration curve gradient using a computing device which possesses the relationship of the measurement sensitivity of the single substance of which the constituent composition varies to the calibration curve gradient that finds the overall concentration of substances A, B and C.  It then sets this calibration curve gradient in mixture concentration measuring microwave type concentration meter 18.  Then, based on the setting of this gradient, it finds phase difference .DELTA..theta. = (.theta.2 - .theta.1) from phase lag .theta.1 of microwaves which are diffused by a reference liquid and phase lag .theta.2 of microwaves dispersed by the mixture.  At the same time, it finds the overall concentration of the mixture using the calibration curve (= a.DELTA..theta. + b) corresponding to the mixture.

La structure comprend des moyens qui forment ces couches de sorte qu'au moins dans la zone limitrophe entre deux couches i adjacentes (i?I¿, i?II¿), vu dans le sens d'incidence de la lumière, l'écart énergétique E¿g? (I) de la première couche i (i?I¿) plus proche du côté d'admission de la lumière est supérieur à l'écart énergétique E¿g? (II) de la deuxième couche i (i?II¿) adjacente à la première et plus éloignée du côté d'admission de la lumière. En outre, dans la direction qui va de la couche p à la couche n, le produit µ?(I) de la couche i (i?I¿) plus éloignée de la couche n est supérieur au produit µ?(II) de la couche i (i?II¿) plus proche de la couche n.

Title: A method of molding a peripherally encapsulated product under heat and pressure utilizing sheet molding compound (smc) or bulk molding compound (bmc), and the peripherally encapsulated product
Inventor: HERRMANN BOB
IPC: B29C70/46
Filed: 2000-03-28
Granted: 2008-09-23
Abstract: A peripherally encapsulated product, such as an oven door outer shell, is molded in accordance with this invention by placing a piece of glass between mold clamping portions of relatively movable closed bodies when the latter are in an open position.  Preferably both bodies are heated and thermosetting polymeric material (SMC or BMC) is placed upon selected areas of one of the mold bodies within and about an area corresponding to an annular mold cavity and outboard of a peripheral edge of a piece of glass.  The glass is clamped between mold clamping portions of the mold bodies which are then progressively closed creating compression forces which extrude the thermosetting polymeric material into the annular cavity and into complete encapsulation of the continuous peripheral edge of the piece of glass. The thermosetting polymeric material is cured, the mold bodies are opened and the product is removed therefrom. The encapsulated product can be provided with post-formed vent openings and/or handle attaching openings or the handle can be integrally molded during the molding process.
