    摘要： Various sensors use an electro-active device (11) electrically connected to a detector circuit. The electro-active device (11) comprises an electro-active structure in the form of a continuous electro-active member (12) curving in a helix around a minor axis (13) which is in itself curved for example in a helix around a major axis (14). On activation by relative displacement of the ends (16) of the device (11), the electro-active structure twists around the minor axis due to the fact that the minor axis (13) is curved. The continuous member (12) has a bender construction of a plurality of layers (21) and (22) including at least one layer of electro-active material so that concomitantly with the twisting the continuous member (12) bends generating an electrical signal detected by the detector circuit. The electro-active device (11) is advantageous as a sensing element in a sensor because it has a large displacement, high sensitivity and low compliance.

    摘要： A method and a system for reselecting of a payment method of a plurality of payment methods associated with a consolidated payment device are provided. The method may include obtaining, at a remote server, a transaction request, responsive to initiation by a holder of a consolidated payment device, wherein the transaction request indicates a first payment method of said plurality of payment methods; authorizing the transaction request, following a process that may include, inter alia, verifying sufficient funds on the first payment method; receiving, at said remote server, a reselection request indicating a second payment method which is different than the first payment method; in a case that the transaction has not yet finalized, authorizing the transaction request with the second payment method and aborting the transaction with the first payment method; and in a case that the transaction has been finalized, authorizing the transaction request with the second payment method and initiating a cancel and refund process for the transaction with the first payment method.

    摘要： Electro-active actuators (310) and methods of manufacturing such actuators are described with such actuators (310) having a plurality of electro-active segments (311) arranged along a curved line with each segment (311) being essentially planar and coupled to adjacent segments (311) through joint sections (312) placed at opposite corners of the segment (311). The actuators (310) exhibit a displacement in a different direction than the direction of displacement of a segment when seen in isolation. They can be made from a continuous tape of material, preferably by die punching.
