  • Patent number: 9409358
    Abstract: A composite structure includes a first laminate and a second laminate. At least one core assembly is located between the first laminate and the second laminate. The at least one core assembly includes a core component and a layer of filler material disposed at a first face of the core component. The layer of filler material at least partially fills selected cells of the core component to a fill depth such that the filler material rigidizes when cured to prevent movement and/or crushing of core component under a pressure applied during a cure cycle of the composite structure.

  • Publication number: 20070257016
    Abstract: The present disclosure generally relates to a device for dispensing a volatile active material that may be direct current (DC) (batteries, fuel cells, solar cells, and the like) powered or chemically powered. More particularly, the present disclosure relates to a battery operated insect repellant device that is easily portable and is capable of providing a sufficient vaporous stream of a volatile insecticide and/or other active agent, to protect a user. The battery operated insect repellant device is configured to operate at high efficiency such that a high percentage of battery energy input into the device is converted to heat used to volatilize the insecticide or other active agent.

  • Publication number: 20070227820
    Abstract: A method for installing an interior structure for a mobile platform is provided. The method includes carrying a lightweight collapsible frame through a man-door of a mobile platform while the collapsible frame is in a collapsed state. The collapsed frame is then expanded to provide at least a portion of a load bearing frame for a mobile platform interior structure. A plurality of interchangeable panels are removable attached to the collapsible frame to form interior surfaces of the mobile platform interior structure.

  • Publication number: 20060257728
    Abstract: The present invention relates to an electrochemical cell comprising an anode, a cathode, and a separator disposed between the anode and cathode. More particularly, the present invention relates to an electrochemical cell comprising, among other things, a separator impregnated with, and/or coated with a layer of, a clay and/or a metal sulfide additive. The present invention additionally or alternatively relates to an electrochemical cell which comprises, among other things, a self-supporting or free-standing thin film separator. The present invention additionally or alternatively relates to an electrochemical cell which comprises, among other things, a separator, wherein at least a portion thereof is covered by an adhesive material that is bonded to the container or a sealing assembly of the cell.

  • Publication number: 20060183020
    Abstract: In an electrochemical cell a container houses a cathode, an anode, a separator between the cathode and the anode, a negative current collector and a sealing assembly for sealing a terminal end of the separator extending outward from between the cathode and the anode. The sealing assembly seals the terminal end of the separator between a first sealing member in sealing relationship with the first face of the separator terminal end and a second sealing member in sealing relationship with the second face of the separator terminal end. In another embodiment, the sealing assembly seals the terminal end of the separator between the sealing assembly in sealing relationship with the first face of the separator terminal end and at least one of the cathode, the anode and the container in sealing relationship with the second face of the separator terminal end.

  • Publication number: 20060183019
    Abstract: Electrochemical cells comprising an anode, a cathode, a container, and a separator are disclosed. At least a portion of the separator is covered by an adhesive material that is bonded to the container or a sealing assembly. The adhesive material provides a mechanical bond between the separator and the container or sealing assembly, and acts to minimize or prevent physical and chemical transport from the anode to the cathode and vice versa. The adhesive material provides a means to utilize thin separators in an electrochemical cell without compromising the shelf life or reliability of the cell. The inhibition of the species migration with the electrochemical cell substantially minimizes or eliminates shorting within the cell or the degradation of shelf life of the cell by limiting the migration of soluble species that can foul one or both electrodes.

  • Publication number: 20060124802
    Abstract: An interior structure for a mobile platform is provided. The interior structure is constructed of a lightweight collapsible frame that can be reconfigured from a compact, substantially flat collapsed state to a non-compact, substantially sprawling expanded state. In the expanded state, the collapsible frame provides at least a portion of a structural load bearing frame for the interior structure. The interior structure additionally includes a plurality of interchangeable panels that attach to the collapsible frame to form interior surfaces of the structure. The panels form such things as the interior wall, ceiling and floor surfaces and can also include amenities such as shelves, lights, beds, closets, electrical outlets, Internet connections and entertainment equipment. The interior structure can be carried though the typical man-door of a mobile platform.

  • Publication number: 20050147872
    Abstract: An electrochemical cell is presented having a pressure dissipation assembly that reversibly ceases cell operation when the internal cell pressure reaches a predetermined threshold. If, once the pressure dissipation assembly is activated, the internal pressure continues to increase to a second threshold, a venting mechanism is activated to release pressurized cell contents from the cell.

  • Publication number: 20050100245
    Abstract: A method for correcting distortions in multi-focus image stacks comprising the steps: acquiring a plurality of N colour images with an optical system; wherein each color image encompasses a plurality of pixels; converting each of two successive colour images of the N images into monochrome images; scaling each of the monochrome images to a conveniently M by M image; calculating a geometric transformation and a radiometric transformation of the two successive images, wherein the geometric transformation and the radiometric transformation is determined by a set of coefficients, which are determined by least square matching, and using the determined set of coefficients from each of two successive images, to correct each image sequentially and thereby constructing the multi-focus image by applying the determined parameter set to each of the successive images.

  • Publication number: 20050084755
    Abstract: The present invention relates to a high capacity electrochemical cell including a cathode that can contain an oxide of copper as an active material, an anode, an electrolyte, and a separator disposed between the anode and the cathode. The oxide can have surface area greater than 0.5 m2/g, and the cathode can include an additive that increases the discharge voltage of the cell. In some cases the additive has a lower voltage than the oxide alone. The additive can have a surface area within the range defined by a lower limit of 0.5 m2/g and an upper limit of 100 m2/g. The anode can include a quantity of mercury below 0.025%.
