Abstract:
The invention relates to a method for determining whether at least one key of a device having multiple keys has been actuated. The device having multiple keys includes a plurality of keys (K1 to Kn) and a plurality of force sensors (C1 to Cn), each force sensor (C1 to Cn) being associated with a key (K1 to Kn), respectively, and capable of supplying a value representing a force which is applied thereto. The method is characterized in that it includes the steps of: obtaining the values (F'1 to F'n ) representing the force applied to each of the force sensors (C1 to Cn); outputting values of the rate of transmission of a bearing force among the keys; suppressing the contribution of each of the force values (F'1 to F'n ) from the bearing force transmitted among the keys using the output rate of transmission values; and determining values (F1 to Fn) representing the bearing force which was applied by the user to the keys (K1 to Kn).
Abstract:
The invention relates to a communication system, comprising n antennas, of which at least n-1 antennas can be used both for the receiving operation and for the transmitting operation, wherein the communication system can carry out an optimization in order to use temporarily unused antennas from case to case for a MIMO system or to prevent transmitting services and receiving services on neighboring antennas from negatively influencing one another, and in order to be able to prioritize communication services and antennas such that it is not possible for an antenna that is in the process of receiving a service to be used simultaneously by another service for transmission.
Abstract:
A method of forming a heat exchanger tube by folding a strip of heat conductive material into a "B" shaped double nosed tube. The strip is progressively plastically deformed to form a pair of corrugations, wherein each of the corrugations includes a series of alternating crests and web segments. An internal nose is defined by an outward extension of the outer most crest followed by an inward curve. The corrugations are then folded inward toward a surface of the strip forming a pair of folded corrugations defining a central wall along the first fold. The folded corrugations are then folded inward toward the same surface of the strip such that the central walls are tightly abutted against each other, and the internal noses are abutted up against a respective portion of the surface along the second fold, thereby forming the double nosed folded tube.
Abstract:
An inflatable cushion for a side of a vehicle is provided, the inflatable cushion having a first sheet of material; a second sheet of material, the first sheet of material being secured to the first sheet of material to define the inflatable cushion; wherein at least a portion of a peripheral edge of the inflatable cushion is defined by a seam wherein the first sheet is secured to the second sheet only by a plurality of stitches and the inflatable cushion maintains an internal pressure in a range of greater than 20KPa and less than 50KPa for at least 1.5 seconds during inflation of the inflatable cushion.
Abstract:
An external containment device for an inflator of an inflatable cushion is provided, the external containment device having: an outlet plate having an outlet opening; a burst disk disposed over the outlet opening; an initiator having an initiator cap; a support pin having a shaft portion and a head portion, the shaft portion being supported by the initiator cap and the head portion contacts the burst disk when the outlet opening is sealed by the burst disk; and wherein activation of the initiator causes the initiator cap to move shearing a portion of the shaft portion from the support pin which allows the burst disk to rupture.
Abstract:
A method of making a structural connection in a metallic tubular assembly is provided. It comprises providing a node having at least two legs and forming a radially extending rib extending from an exterior surface of each of the legs by deforming a corresponding interior portion of each of the legs. At least one tube is provided having a radially extending flange adjacent an open end. The tube is placed over the exterior surface of one of the legs abuts the radially extending flange and the radially extending rib. By applying opposing forces to one of the legs and one tube to hold the radially extending flange and the radially extending rib in abutting contact at a joint, resistance welding can take place at the joint when at least one electrode is applied to the joint.

Abstract:
A selective catalytic reduction (SCR) catalyst control system and method for an engine is disclosed. Urea injection to an SCR catalyst is determined based on an SCR catalyst model, which determines a value of stored NH3 in the SCR catalyst based on the NOx engine emission value, the SCR catalyst temperature, the quantity of urea supplied to the SCR catalyst and a pre-determined efficiency of conversion of NOx gases. A target value of stored NH3 and the value of stored NH3 in the SCR catalyst is then used to determine a stored NH3 differential, which is then used to calculate urea injection.
Abstract:
An improved bending apparatus for bending a radiused corner at a window in a brazed heat exchanger core where no tubes and fins are located. A cylindrical mandrel and sliding pressure die are designed to completely surround the manifold in the areas of the window and provide a continuous, rolling contact area or profile support around the manifold as the bending moment is applied.
Abstract:
A fuel injector for an internal combustion engine, the fuel injector comprising an injector body, a fuel supply passage defined in the injector body, the fuel supply passage containing fuel under high pressure in use of the injector, a pressure sensor for measuring the pressure of fuel in the passage in use, wherein the pressure sensor is situated within the injector body and is separated from fuel in the passage in use, and a method of fuel injection, comprising constructing an hydraulic behaviour profile by fuel pressure measurement, using the hydraulic behaviour profile to predict fuel pressure that will prevail in a fuel injector during an injection event, and supplying a control signal to the fuel injector to control the amount of fuel injected during the injection event in accordance with the predicted fuel pressure. By predicting the fuel pressure that will prevail during an injection event, the fuel delivered during the injection event can be accurately controlled.
