    Abstract: This thermoplastic elastomer is present in a substantially solid state suitable for use as a binder for a propellant, explosive, and/or gas generant of a supplemental restraint system. The thermoplastic elastomer is formed from a composition including A blocks which are crystalline at temperatures below about 75° C. and B blocks which are amorphous at temperatures above about −20° C. The A blocks are derived from oxetane derivatives and the B blocks are derived from oxiranes and derivatives thereof. The A blocks and B blocks are end-capped with a diisocyanate having a first isocyanate moiety that is substantially more reactive with the terminal groups of the blocks than the second isocyanate moiety, whereby the more reactive first isocyanate moiety is capable of reacting with the terminal groups of the blocks, leaving the less reactive second isocyanate moiety free and unreacted. The end-capped A blocks and the end-capped B blocks are linked together with a linking compound having two isocyanate-reactive groups which are sufficiently unhindered to react with the free and unreacted isocyanate moieties of the end-capped polymers.

    Abstract: A method and system for beamforming a multi-element array using time delays is provided. The array includes transmit array elements and receive array elements. Each of the array elements includes a processor. Modulation and demodulation functions are performed at the processors of each array element. The modulation and demodulation functions utilize receive time offsets and phase shifts, and transmit time offsets and phase shifts, respectively. The receive time offsets and phase shifts, and the transmit time offsets and phase shifts are determined by a central processing unit in order to beamform received signals and transmitted signals, respectively. The array elements are arranged in a daisy chain fashion in order to facilitate communication of control parameters, communication of bits to be transmitted and distributed combining of demodulated baseband samples from one array element to another and communicating the combined samples to the central processing unit.

    Abstract: A tool for securing or removing a cylindrical object by grasping the object and rotating it about its central axis comprises a band clamp assembly and a hinged drive assembly. The band clamp assembly comprises a band clamp which is tightened by means of a thumbscrew or hex nut. The hinged drive assembly comprises at least four segments connected by at least three hinges. The end-segments of the hinged drive assembly have on their obverse surfaces raised slots through which the band clamp is slipped. The band clamp assembly then fits over and around a cylindrical object such as an oil filter canister. The clamp is tightened around the canister body such that the inner surface of the clamp and the reverse surfaces of the end-segments, which are knurled or scored, are in frictional contact with the canister wall. In the preferred embodiment--a hinged drive assembly having five segments connected by four hinges, rotation of the canister about its central axis is accomplished by one of three means. The tool may be engaged with a ratchet wrench, which fits into a square hole in the center mid-segment, or with a force bar implement, which slips through two rings attached to the obverse surface of the center mid-segment. Torque also may be applied manually by grasping the center mid-segment and employing the necessary wrist action.
