Title: Measurement of adherence between a vehicle wheel and the roadway
Inventor: TRAVERT PIERRICK
IPC: G01L5/00
Filed: 2000-08-08
Abstract: A pneumatic tire has two elements on its tread at different distances from the tire axis. The element nearest the axis contains sensor(s) detecting at least a tangential force between the element and a road surface, etc. In normal use of the tire both elements contact the surface; under some operating conditions the first element slides on the surface. Independent claims are included for the following: (a) detecting adhesion between a deformable tire tread and a surface using a tire as above includes producing a signal indicative of the tangential force. Variation in this signal indicates changes in adhesion. The friction between the element and the surface and the potential adhesion between of the tire are calculated; and (b) detecting adhesion between a deformable tire tread and a surface using a tire as above includes producing a signal indicative of the tangential force. A first variation in this signal indicates changes in adhesion. A second variation in the signal as the element contacts the surface is detected. An adhesion limit is determined as a function of the two variations.

Abstract: A fabricated box stud product and method of making the product from oriented strand board (OSB) . The box stud is made from two T-shaped flanges coupled to two elongated rectangular webs forming an open-ended rectangular OSB tube . The OSB tube is capped by two OSB end plugs, one at each open end of the tube. Foam insulation may occupy the hollow of the box stud. The box stud is manufactured as a 2 by 4, or as a 2 by 6, and is preferably 8 feet long. The manufacturing process entails feeding an OSB sheet into a saw and cutting certain OSB sheets into webs and others into notched flanges using a diamond-toothed Gang Dato and a Gang Saw. A ribbon of hot glue coats each notch of each flange. The webs and flanges are then dropped into an assembly area over a continuous chain drive extending between two sprockets. An assembly pocket having computer automated guide fingers positions the webs and flanges with clamp fingers and clamp rollers which simultaneously provide the necessary horizontal and vertical forces, respectively, to ensure full contact or adhesion. The end plugs are either extruded-in-place using pulverized OSB scraps and injected into each open end of the OSB tube, or cut to fit from OSB scrap stock, dipped into a vat of glue, and placed into each open end of the OSB tube. Foam insulation is injected into the stud through a hole in an end plug or elsewhere

Abstract: A terrestrial repeater is disclosed for use in a satellite transmission system that may also include a plurality of satellites. The terrestrial repeaters are implemented as OFDM transmitters to minimize the channel impairments caused by multi-path propagation. The OFDM terrestrial repeaters differentially encode the transmitted signal over frequency, as opposed to time, in order to avoid channel phase distortion. The OFDM receiver allocates two unmodulated sub-carriers as pilot bins and thereby provides two sub-carriers as a reference within each OFDM symbol. At the OFDM receiver, the two unmodulated pilot bins contain no phase information and provide a reference for the differential demodulation performed by the OFDM receiver.  The OFDM transmitter operates in two modes, namely, a normal mode and a transmitter identifier information (TII) mode. The TII mode contains all of the functions of the normal mode, and also transmits a repeater identification signal with the customer data, using the inactive OFDM sub-carriers (bins). In a normal mode, the OFDM  transmitter optionally fills unused (inactive) sub-carriers with zeroes and in a TII mode, the OFDM transmitter uses at least some of the unused (inactive) sub-carriers to transmit the transmitter identifier information (TII). The predefined TII value is mapped onto a set of complex symbols. The TII signal facilitates the receiver test equipment in associating the received signal with the terrestrial repeater(s) that generate the TII signal.

Abstract: Tin is added to a zinc cathode target to enhance the sputter efficiency of the target. Films deposited using the cathode, e.g., greater than zero but less than 10 weight percent tin and greater than 90 but less than 100 weight percent zinc improve the chemical durability of a high transmittance, low emissivity coating stack over coating stacks having zinc oxides without tin oxide. High transmittance, low emissivity coating stacks are heated with the heated coating having reduced haze by selecting the thickness of metal primer layer between an infrared reflective film, e.g. a silver film and a dielectric film, e.g., a 52-48 zinc stannate, zinc oxide, tin oxide film or a zinc oxide film. Also disclosed are enhancing films that lower the resistivity of silver films deposited thereon and improve chemical durability of the coating stack.

Abstract: An inflation device (5) for an inflatable article (such a life jacket), includes a housing (8) for holding a container of pressurised fluid (6), a displacement means (12) including a piercing means (15) displaceable so as to penetrate the container (6) and allow the release of said pressurised fluid, and actuation means (23, 27, 28, 29) having engaging co-operating elements (17, 25) which engage to retain the displacement means (12) in an unactuated configuration. The actuation means (23, 27, 28, 29) release the displacement means (12) both through the presence of water or by manual operation. The co-operating elements (17, 25) are substantially radially arranged. The line along which the displacement means (12) acts may be coaxial with the radii of the co-operating elements (17, 25). One of the co-operating elements (17) is capable of inward radial movement, and the actuation means (27, 28, 29) operates to prevent that co-operating element's (17) radially inward movement. Similarly, one of the co-operating elements (25) is capable of outward radial movement, and also prevented by the actuating means (23). When the actuation means (23, 27, 28, 29) is triggered (by water or by the manual release), the movement of one of the co-operating elements (17, 25) causes the displacement means (12, 15) to pierce the container.

Title: Call delivery systems for roaming prepaid subscribers
Inventor: COOPER JOHN R
IPC: H04W8/12
Filed: 1999-11-24
Abstract: The invention provides systems and methods that operate to provide seamless roaming to a prepaid subscriber in as many markets as possible. To that end, the systems of the invention include a location register (LR) that can determine the type, or class, of serving market with which the roaming subscriber is registering. Once the class of the serving market is identified, the LR can modify a subscriber's profile as a function of this class, and return to the serving market a profile that will allow the serving market to employ the prepaid platform that services the subscriber and thereby provide services to the roaming subscriber. In optional embodiments, the LR may also respond to location requests from the prepaid platform. The location information may be employed by the subscriber to determine a rate structure for a call, and thereby decrement the subscriber's balance as a function of, at least in part, the location of the roaming subscriber.
