An example kiosk for accepting a portable electronic device from a client in exchange for payment, associated method and systems are described. The kiosk may include at least one display, an imaging chamber that includes at least one camera and one or more mirrors fixedly-arranged to capture images of a portable electronic device, at least one communication connection to a remote server and/or operator, and at least one computer. The computer may be configured to, in conjunction with the remote server and/or operator, capture one or more images of the portable electronic device in the imaging chamber while said at least one camera and said mirrors remain in unchanged positions. The computer may also transmit the captured images to the remote server and/or operator, receive an acceptance of the offered payment amount based upon an offered payment amount for the portable electronic device received from the remote server and/or operator, and provide for secure deposit of the portable device in the kiosk.

A valet vault is described herein. The valet vault may be constructed with components that result in improved strength and prevent theft. In one example embodiment, the vault may comprise a service side, an attachment side, and four exterior sides, a lockable utility box, a secured storage area being accessible through a door where a hinged end of the door is pivotally connected to a door frame by at least one hinge, and a security plate substantially separating the secured storage area and the lockable utility box. The vault may comprise a catch/latch to stop the door. The vault may comprise an illuminatable sign that does not compromise the security of the secured storage area. The door may comprise reinforcements. The vault may be a podium or be coupled to a wall.

A gun safe having one or more sliding, pivoting drawers configured to hold a series of long guns in a vertical position within the safe. Each drawer has firearm supports and a slide mechanism that allows the drawer to be moved out of the gun safe in a direction substantially perpendicular to the door opening. The drawer may be pivoted when withdrawn. This arrangement allows a user unrestricted access to any firearm stored on either side of the sliding gun drawer.

The present invention relates to an innovative system and method of design in compact archive cabinets used to store valuable inventory, pieces of art, and other materials, items and documents that need preservation in museum, library or office-like environments, that provides passive humidity and fire control inside, which employs special dual-purpose insulating frames (3), perforated metallic sheets (2) and cold action seals (6) packed in a two-layer construction, all arranged in cabinets that enable, mostly thanks to the said seals, prevention of flames, heat and smoke ingress through the gaps between any two adjacent cabinet modules.

The application describes generation of a data structure that enables comparison of any diamond to any other diamond. The data structure is generated via a sampling process and a computer system for acquisition of diamonds of a valid statistical sample having a predefined sample size. The process comprises tabulating the frequencies that diamonds of various grade combinations are available in an overall population of diamonds, then using a bidding process described herein to acquire a valid statistical sample of diamonds. The data for the sample of diamonds are then inputted into a Linear Programming and Mixed-Integer optimizer configured to sort all diamonds of the sample into sets with a median that is a minimal distance from the median on a scarcity basis, subject to various constraints, such as the number of diamonds in each set and a minimum total carat weight.

A diamond asset comprising one or more diamonds and an encryption chip is used to asset-back a cryptographic token that can be used to conduct transactions. A user device executes an application programming interface configured to access a blockchain that stores a smart contract associated with the cryptographic token backed by the value of the one or more diamonds. When the user device receives an instruction to perform a transaction related to the cryptographic token, the user device causes the encryption chip to sign the smart contract. In response to determining that the smart contract was signed by the encryption chip, the user device causes the transaction to be performed.
