Abstract: The present invention is directed to an audience response communication system that reduces transmission traffic by utilizing a beacon transmission as a vehicle to transmit additional data. A typical system comprises a base unit and a plurality of remote input devices. The base unit and the remote input devices include processing units and communication devices such that data is transmitted between the base unit and the remote input devices. The beacon, which serves the typical uses of a beacon, further serves to deliver information such as vote acknowledgements, welcome messages, or the like.

Abstract: The present invention is directed to an audience response communication system comprising a base unit and a plurality of remote input devices. The audience response and communication system lowers the risk of undelivered data transmissions by enabling the remote input devices to sequentially transmit responses via multiple transmission channels until a vote acknowledgement message is received, or a predetermined number of attempts is made.

Abstract: A method of testing at least one tire of a test vehicle provided with a sensor for measuring the forces and moments of at least one test tire, the method including coupling the test vehicle to an anchor vehicle wherein the coupling restricts the lateral and longitudinal and yaw movement of the test vehicle relative to the anchor vehicle such that the anchor vehicle maintains the course and velocity of the test vehicle; and performing testing of the test vehicle while the test vehicle is coupled to the anchor vehicle.

Abstract: A bulk ionically conductive polymer gel is prepared by dissolving a salt such as lithium trifluoromethanesulphonate (which would provide lithium ion conductors) in an organic compound such as N-formylpiperidine. The organic compound dissolves the salt at 20.degree. C. but is not a solvent at 20.degree. C. (though it is at 215.degree. C.) for polyethylene terephthalate. The last-named is a crystallizable polymer which is added in a minor amount at a high temperature to the other components and provides the required mechanical rigidity for the product at lower temperatures.

Abstract: An ionically conductive, ion-containing polymeric material prepared from an amorphous polymer and a source of ions and having a bulk ionic conductivity at 20.degree. C. and 10 kHz greater than 10.sup.-6 .OMEGA..sup.-1 cm.sup.-1, wherein the copolymer comprises a backbone from which depends at least one residue of the formula: ##STR1## wherein: n represent a number greater than 1; andR represents a hydrogen atom or substituted or unsubstituted lower alkyl group.

Abstract: This GTO thyristor comprises: (i) a cathode layer that is divided into a large number of cathode-layer fingers, (ii) a gate layer contiguous with the fingers, with a PN junction J1 between each finger and the gate layer, (iii) a cathode electrode on each finger, and (iv) a gate electrode on the gate layer having portions surrounding the fingers disposed in spaced relation to the fingers. Turn-off of the GTO thyristor is effected by forcing a turn-off current to flow between the cathode electrode of each finger and the gate electrode through the associated PN junction J1. This PN junction at each finger has a centrally-located region that is characterized by an avalanche voltage that is substantially lower than the avalanche voltage that characterizes this junction in the region of the junction surrounding the centrally-located region, and this relatively lower avalanche voltage enhances the current turn-off capabilities of the GTO thyristor.

Abstract: Melt processable fibre-forming polyesteramides comprising residues of one or more aminophenols selected from p-aminophenol and p-N-methylaminophenol and residues of one or more dicarboxylic acids characterized in that the polyesteramide contains a balance of linear difunctional residues and dissymmetric difunctional residues derived from either the aminophenols or the acids chosen to give a product which melts below its decomposition temperature and exhibits optical anisotropy in the melt.

Abstract: The manufacture of a poly(alkylene arylene dicarboxylate) by reaction of an aromatic dicarboxylic acid in the solid state with an alkylene oxide wherein a major part of the reaction mass forms a solid phase throughout the reaction, in the presence of phosphorous acid as catalyst.
