Abstract: An inflator includes a generant chamber that houses a quantity of gas generant. The chamber has a plurality of gas exit holes that are positioned along the length of the generant chamber. A filter is added exterior of the chamber. In fact, the filter may be positioned on the exterior of the generant chamber. Straps may encircle the inflator. The straps are attached to studs that will operate to mount the inflator. The position of the straps may be adjusted and tailored to apportion the amount of inflation gas that is directed into each chamber of a multi-chambered or two-chambered airbag.

Abstract: An airbag inflator diffusion system having a thin profile. The diffusion system includes an airbag inflator that is inserted into a sleeve. The sleeve has overlapping longitudinal edges positioned so that the sleeve tightly circumscribes the inflator. Engagement tabs are formed in one longitudinal edge of the sleeve and fold through perforations formed adjacent the other longitudinal edge. Upon activation of the inflator, the sleeve expands radially forming an exhaust passage through which exhaust gas may travel. The folded engagement tabs and their corresponding perforations limit the radial expansion of the sleeve.

Abstract: A device for measuring the diameter and circumference of a flexible circular object which includes two movable gauge pieces. The flexible circular object to be measured is place between the two gauge pieces and compressed thus forcing the object to be measured to conform to the shape of the gauge. The distance separating the gauge pieces is measured and is compared to the gap produced by a reference. The length of separation is converted to diameter and circumference measurements by appropriate means.

Abstract: A real time geophysical survey system and method. The system comprises a base station, one or more data acquisition vehicles, and a global positioning satellite network. The base station is provided with a computer, radio communication equipment, and means for determining from signals of the satellite network the position of the base station. The data acquisition vehicles are each provided with geophysical survey instrumentation, radio communication equipment, an acquisition vehicle positioning display, and means using signals of the satellite network to calculate at least an approximate horizontal position of the data acquisition vehicle. During a survey, by periodically polling each data acquisition vehicle, the base station determines the location of each data acquistion vehicle and accurately tracks its position, both with respect to the base station and with respect to a preselected survey pattern over the geographic area to be surveyed.

Abstract: A real time geophysical survey system and method. The system comprises a base station, one or more data acquisition vehicles, and one or more fixed reference stations. The base station is provided with a positioning system, suitable survey instrumentation, a computer, and radio communication equipment. The data acquistion vehicles are each provided with a positioning transponder, a positioning display, suitable survey instrumentation, and radio communication equipment. During a survey, by periodically polling each vehicle's positioning transponder, the base station positioning system tracks the position of each vehicle with respect to both the base station and the fixed reference stations. Data regarding each vehicle's position are then provided to the base station computer, and the base station transmits signals to the positioning display aboard each vehicle so as to guide the vehicle along a preselected survey pattern.
