Abstract: Embodiments described herein provide a computer-implemented method of creating a digest of a document. The document to be processed and analysed may be a physical document, or it may already be in a digital form. In the case of starting from a physical document, the document is first scanned, so as to obtain an image of the document. The digital document is then processed using an algorithm or function to obtain one or more datasets comprising a plurality of position independent values. Each of the datasets may correspond to a different line of text or field of text within the document. The one or more datasets are then encoded, the encoded data being used to generate a digest associated with the document, and wherein the digest comprises a plurality of short hashes corresponding to each dataset. The generated digest can then be used to print a digital signature on the document, which can be used to later verify the authenticity of the document or a copy thereof.

Abstract: A fabric for use in the manufacture of an inflatable air-bag, the fabric having interwoven warp fibers and weft fibers which are arranged substantially perpendicular to one another, one or more of the warp and weft fibers being at least partially coated with an adhesive substance to increase the friction between the warp and weft fibers at their intersections. In another embodiment, the fabric is formed from fibers having a central core and another sheath.

Abstract: A method of forming a fabric for an air-bag, the method comprising providing a plurality of yarns, each yarn being formed from a plurality of individual fibres; applying an activatable additive or coating to each yarn, the additive or coating initially not being activated and wherein, prior to activation, the additive or coating presents little or no impedance to the relative movement of the fibres within the yarn and, following activation, the additive or coating binds fibres within the yarn to one another to prevent or hinder relative movement of the fibres in the yarn with respect to one another; and passing the yarns through an activation zone including a compressing component which applies a compressive force to the yarns, the additive or coating being activated as the yarns pass through the activation zone so that the yarns each have a substantially flat configuration.

Abstract: A quick release fastener for an end fitting of a safety belt having spaced apart first and second frame, a lockable insert tongue insertable between the frame plates, and a locking element moveable between a locking position in which the insert tongue is locked between the frame plates, and a release position. A locking element has at least two anchor surfaces facing one another, which at least form the stop at one outer face of the frame plates or of the insert tongue. In this way, a shockproof quick release fastener is provided which can be released without a special tool.

Abstract: An airbag having an outer skin enclosing at least one gas chamber is disclosed. The outer skin is made at least in parts of polymer material with the polymers of the polymer material being made by polymerisation of monomers. In order to reduce the total consumption of fossil based raw materials during the life cycle of a vehicle, at least a part of the monomers are sustainable based monomers being produced from a renewable raw material.

Abstract: A method of preparing a gassed water-in-oil emulsion explosives composition from a gasser solution of an inorganic nitrate, an ammonium species and an optional accelerator which is added to an emulsion explosive composition, reacts and forms gas bubbles is disclosed. The emulsion explosive composition is composed of a discontinuous aqueous phase, a continuous water immiscible organic phase, and an emulsifier. The reaction between the gasser solution and the emulsion explosive composition is such that the emulsifier does not undergo chemical attack.

Abstract: An airbag for protecting a vehicle occupant comprising a first and a second material layer each having edge regions, wherein the first and the second layers are sewn together along the edge regions. A fastening section adapted for attaching to a part of the vehicle and connecting to a gas generator configured to inflate the airbag with a gas in response to an accident. A first and a second chamber region disposed opposite a dividing seam, wherein each of the material layers includes a first and a second material section each matched to one of the first or second chamber regions.

Abstract: An air bag formed from two layers of fabric using a one-piece weaving technique has a peripheral seam at the edge of a region adapted to be inflated. Beyond the seam there are a plurality of chambers and gas escaping from the inflated region through the seam must inflate these chambers thus creating a back pressure to reduce the flow of escaping gas.

Abstract: An air-bag has a primary gas flow duct leading from a gas generator to one or more zones within the air-bag which are to be inflated. The air-bag has a separate inner gas flow duct mounted within the outer gas flow duct. The inner gas flow duct and the outer gas flow duct have areas thereof secured together in the region that is to be connected to the gas generator.

Abstract: A method of assembling an air-bag comprises the steps of taking a gas-flow duct which is to be located within a gas-flow passage of an air-bag, and applying a hot-melt adhesive to one or more locations on the exterior of the gas-flow duct. The hot-melt adhesive is permitted to cool to a state in which it is substantially solid and exhibits little or no tack. The gas-flow duct may then be inserted into the gas-flow passage without affecting the adhesive in any way. Subsequently heat is applied so the hot-melt adhesive at least partially melts. The adhesive then adheres the gas-flow duct to that part of the air-bag defining the gas-flow passage. The hot-melt adhesive may cure over a period of time to form a substantially cross-linked adhesive.

Abstract: An air-bag (1) has a primary gas flow duct (11) leading from a gas generator to one or more zones within the air-bag which are to be inflated. The air-bag has a separate inner gas flow duct (12) mounted within the outer gas flow duct. The inner gas flow duct (12) and the outer gas flow duct (11) have areas (22 and 23) thereof secured together in the region that is to be connected to the gas generator.

Abstract: An air-bag in the form of an inflatable curtain has a plurality of zones each provided with vertically extending cells defined by seams. Uninflatable regions are provided, the uninflatable regions being provided with oval apertures. On deployment of the inflatable curtain, the oval apertures will distend to become circular, enabling the uninflated region effectively to stretch to moderate the tension generated between two anchoring points connected by straps to the lower edge of the air-bag.
