  • Patent number: 9728290
    Abstract: Among other things, an energy shield (212) for a radiation system, such as a security imaging system, is provided. The energy shield is comprised of one or more flaps (300). At least one flap defines an aperture (320) providing a demarcation between a first flap segment (322) of the flap and a second flap segment (324) of the flap. The aperture (e.g., and a flexible member (326) positioned spatially proximate the aperture) provide for (e.g., facilitate) movement of the second flap segment relative to the first flap segment. In this manner, an amount of force required to be applied by an object to pass by the flap may be reduced when the object is small and merely contacts the second flap segment, for example. In this manner, baggage jams may be mitigated, for example, by reducing the likelihood that certain objects will be impeded from passing through the energy shield.

  • Patent number: 9293293
    Abstract: The objective of the present application is to suppress the occurrence of flares and to reduce the amount of secondary electrons arising at an aperture provided to the lead-out electrode of an electron gun. By coating a thin film having a low rate of secondary electron emission such as carbon onto the aperture of a lead-out electrode closest to an electron source in an electron gun, it is possible to reduce the amount of secondary electrons arising. Secondary electrons arising at the lead-out electrode, are reduced, and so as a result, flare is reduced. By incorporating two apertures to the lead-out electrode, and applying to the two apertures a potential that is equipotential to the lead-out electrode, it is possible to eliminate an electric field from seeping from under to over the lead-out electrode. Secondary electrons arising when an electron beam impacts the lead-out electrode cease to incur force in the direction of passage from the lead-out electrode, and consequently there is a reduction in flares.

    Abstract: In accordance with the present invention, there is provided a system and methodology for sorting and/or distributing items and articles being shipped to a receiving party through private and/or commercial delivery systems. Various characteristics of an article being shipped are obtained and assembled in a database. In an exemplary embodiment, the descriptive characteristics of the article are acquired at a first site and the processing and desired disposition of the article is determined at a second site which is physically separate from the first site. The descriptive characteristics of the article being shipped are displayed at the second site and are sufficient to identify the article to a processing individual located at the second site. The processing individual is then enabled to indicate a desired disposal of the article from the second site without being exposed to the physical article located at the first site.

  • Patent number: 9087617
    Abstract: An X-ray obscuration (XRO) film comprising one or more metallic wire mesh layers and an adjacent layer of indium foil having portions which extend into openings of the wire mesh and in contact with metallic portions thereof. The XRO film can be capable of absorbing at least a portion of X-ray energy thereby creating an interference pattern when the XRO film is coupled with an electronic circuit and placed between an X-ray source and an X-ray detector and subjected to radiographic inspection. The interference pattern can create sufficient visual static to effectively obscure circuit lines in the electronic circuit when subjected to radiographic inspection techniques. The XRO film can be substantially thinner than existing solutions for preventing X-ray inspection with an exemplary embodiment being no more than 5 mils thick. The metallic XRO film can also provide electromagnetic shielding and/or heat dissipation for electronic circuits.

  • Publication number: 20150115138
    Abstract: In one embodiment, a sensing device comprising a substrate, an emitter, a receiver and a shield is disclosed. The shield may be arranged to shield at least partially the emitter and the receiver. The shield may have a stopper and a reflector cup. The stopper may be a retention mean for engaging the substrate adjacent to the receiver such that a shield surface of the shield may be arranged distanced away from the receiver. The reflector cup may also engage the substrate adjacent to the emitter, so that the shield surface may be arranged distanced away from the emitter. In other embodiments, a sensing apparatus and a sensor having a stopper or a retention member are disclosed.

  • Patent number: 9018605
    Abstract: A nuclear fusion reactor first wall component includes a copper alloy element, an intermediate metal layer made from niobium and a beryllium element, directly in contact with the intermediate metal layer. The intermediate niobium layer is further advantageously associated with a mechanical stress-reducing layer formed by a metal chosen from copper and nickel. This mechanical stress-reducing layer is in particular arranged between the intermediate niobium layer and the copper alloy element. Furthermore, when the mechanical stress-reducing layer is made from pure copper, a layer of pure nickel can be inserted between the niobium and the pure copper before diffusion welding. Such a component presents the advantage of having an improved thermal fatigue behavior while at the same time preventing the formation of intermetallic compounds at the junction between the beryllium and the copper alloy.
