  • Patent number: 10460252
    Abstract: A system and method improves the probability of correctly detecting an object from a collection of source data and reduces the processing load. A plurality of algorithms for a given data type are selected and ordered based on a cumulative trained probability of correctness (Pc) that each of the algorithms, which are processed in a chain and conditioned upon the result of the preceding algorithms, produce a correct result and a processing. The algorithms cull the source data to pass forward a reduced subset of source data in which the conditional probability of detecting the object is higher than the a priori probability of the algorithm detecting that same object. The Pc and its confidence interval is suitably computed and displayed for each algorithm and the chain and the final object detection.

The resilient plate material formed of a resilient material has a curved shape prior to assembly. Upon assembly, end portions are pressed and the resilient plate material is resiliently deformed into a flat plate. Due to the resilient force, the first to the third lamination layer are pressed against the base, and are caulked and fixed by the caulking members. Since the first to the third lamination layers are pressed due to the resilient force of the resilient plate material, the number of parts can be reduced and easy manufacturing can be achieved.

  • Publication number: 20090295657
    Abstract: A radiating element made from a conductive-nonwoven web is incorporated into a signal emitting apparatus. The signal emitting apparatus, for instance, may comprise an RFID tag. The conductive-nonwoven web contains, in one embodiment, conductive fibers combined with pulp fibers. The conductive fibers may comprise carbon fibers. The nonwoven web may be made using a conventional paper-making process. The resulting conductive web is not only well suited for use as an antenna, but is also relatively inexpensive to manufacture and can be easily incorporated into numerous products.

  • Patent number: 7626561
    Abstract: A signal carrying apparatus (101) for transmitting a signal by variation of electromagnetic field comprises a meshed first conductor portion (111) which serves as a conductor in the frequency band of the electromagnetic field, and a second conductor portion (121) of which external shape is sheet-like and which serves as a conductor in the frequency band of the electromagnetic field and arranged substantially in parallel with the first conductor portion (111). In the interval region (131) between the external shape of the first conductor portion (111) and the external portion of the second conductor portion (121), and in the planar leak region (141) located oppositely to the interval region (131) across the external shape of the first conductor portion (111), the electromagnetic field propagating in that frequency band has a strength attenuating exponentially with the distance from the external shape of the first conductor portion (111) in the leak region (141).
