Abstract: Systems and methods are described providing blockchain-based footwear authentication and tracking. A server that includes a cryptographic blockchain database may receive and add to the blockchain a genesis block that includes both a feature vector, derived from a high-resolution photograph of a portion of a footwear item, and a low-resolution version of the high-resolution photograph. The server may subsequently receive a request for on-chain blocks referencing a first set of identifiers, including an identifier for the genesis block, from a verifier application. A comparison may be performed by the requesting application between the low-resolution version from the genesis block and a locally-captured photograph of a locally-possessed footwear item. If a match is detected, the application may receive an authentication input, which may cause a transaction block to be sent the server if the verification is part of a transfer of ownership of the locally-possessed footwear item.

Abstract: An extended length or linear type light fixture having a lighting element placed on pivoting members locked into the fixture is provided. The fixture is of the typical sealed beam fixture used in outdoor or places having an environment harmful to electronics. The present invention allows the fixture to be installed, often at elevated positions, relative to the ground, or in places not easily accessible, and allows the light element to be pivoted so that even after the light fixture is installed, the light from the fixture can be pivoted to project light where more desired. As such the installation of lighting fixtures is simplified and adjustments are possible even after installation and upon the change of conditions and as needed for immediate change and restoration. The fixture provides a high grade light element with easy adjustments for use in a variety of situations that previously required removal and reinstallation of light fixtures or the use of additional fixtures at increased costs.

Abstract: A housing for a lighting fixture is provided such that the fixture has IP65 or better impermeability. The housing includes a base pivotally connected to a lid, the lid including a light permeable diffuser, a pliable gasket between the lid and base, and fastening means including a fastener on the lid and a flange on the base. The flange is provided with a linear cam portion diametrically opposed to the pivot, and an opening defined in the flange, such that when the lid is pivoted to proximity with the base and the fastener is tightened, the distal end of the fastener will contact the linear cam pulling the lid into sealed relation with the base. The fastener being tightenable such that its distal end enters the opening in the flange, thereby locking the lid onto the gasket and base to form an IP65 impermeable relationship.

Abstract: In one aspect, the invention relates to a method for fixing a short nucleic acid in a biological sample. In another aspect, the invention relates to a method for detecting a target short nucleic acid in a biological sample. The method includes contacting the biological sample with an aldehyde-containing fixative, and subsequently contacting the sample with a water-soluble carbodiimide. In a further aspect, the invention relates to a kit for fixing a short nucleic acid in a biological sample. The kit includes a support substrate for holding the sample; an aldehyde-containing fixative; and a water-soluble carbodiimide.

Abstract: A display assembly for attachment to a vehicle is provided that includes a panel assembly for receiving a display; a mounting arm removably extending from the panel assembly; and a strap assembly having a connector portion connected to the mounting arm and a strap portion for removable engagement with a rail of a roof rack that is mounted on the vehicle.

Abstract: A display assembly for attachment to a vehicle is provided that includes a panel assembly for receiving a display leaf; and a strap assembly connected to the panel assembly. The strap assembly is removably connected to a roof rack to removably mount the display assembly to the vehicle. This allows the panel assembly to extend downwardly along a side of the vehicle, such that the direction of travel of the vehicle is substantially in the vertical plane of the panel assembly.

Abstract: A portable display manufacture (15) for viewing a display (19) positioned on its leaf (18) between a support panel (20) and a transparent panel (17) and which is mountable upon a vehicle's sidewall (46) or its rearwall or tailgate (111). Hinges (27) provide for open and closed modes of manufacture (15). Suction cup members (44, 45) and telescopic arms (50) with their strap assemblies (83) connect manufacture (15) to sidewall (46) and rack bar members (84, 85), respectively, on the roof (86) of vehicle (16). Strap assemblies (83) are rotatable so that they can be connected to either a rack bar member (84) or rack bar member (85). Foldable braces (63) lock in extended position for arms (50) and strap assemblies (83) to operate and fold to provide a collapsed mode for manufacture (15).
