Abstract: A deterministic encryption key generating method along with a cryptographic system is disclosed as a component in a battlespace management system or platform within the battlespace. The systems method uses the intersection of an equation representing a polynomial or two-variable quadratic (PQ-Equation) with a secure and secret 3-dimensional mathematical geometric shape, or manifold, to generate an ephemeral symmetric encryption key. Digital objects, files, and data can be cryptographically secured using this process with a unique per-file or per-data object key, which is destroyed after each use. The process combines coefficients of a PQ-Equation mapped onto the manifold to create or recreate the key. PQ-Equation coefficients are stored within the protected file, accessible via the client and transmitted to the computational server possessing the secret manifold.

The process combines coefficients of a PQ-Equation mapped onto the manifold to create or recreate the key from an identifier, for instance values for the PQ-Equation.

Abstract: A system and method for trialing a modular hip replacement system permits evaluation and replication of the anatomic anteversion rotational angle of the femur. In one embodiment, a femoral hip implant kit includes at least one distal implant and a plurality of femoral heads, each of the plurality of femoral heads having a diameter different from the diameter of the other of the plurality of femoral heads. The kit includes a proximal trial housing with a bore within the housing, the bore configured to receive a portion of the distal implant, a collet located within the bore, the collet including an outer wall portion extending between a top surface portion and a bottom surface portion, a collapsing member for engaging the portion of the distal implant and for forcing the top surface portion of the collet toward the bottom surface portion of the collet along a first axis.

Abstract: The present invention relates generally to identification documents. In one implementation, a provided method includes: obtaining optical scan data associated with text characters provided on an identification document to obtain first data; using at least a portion of the first data to facilitate decryption of information—not the text characters—carried on or in the identification document. The information corresponds to the identification document or to an authorized bearer of the identification document. In another implementation, a method is providing including: obtaining optical scan data associated with an identification document to obtain first data; obtaining second data from the identification document, the second data comprising encrypted data; communicating the encrypted data and the first data to a remote device, the remote device decrypting the encrypted data with at least reference to the first data; and receiving decrypted data from the remote device.

Abstract: The present invention relates generally to validating and providing physical objects. In one implementation, a physical object includes a first digital watermark carried thereon. The first digital watermark includes a first plural-bit message representing at least a reduced-bit representation of a biometric corresponding to an authorized bearer of the physical object. The physical object further includes semantic information carried thereon. At least a portion of the semantic information corresponds to the authorized bearer of the physical object. In another implementation, an apparatus is provided to validate physical objects. In some cases the objects include identification documents.

Abstract: Security documents which has multiple fields or areas each of which contains information that is perceptible in more than one way: One field can contain a visually perceptible image and a digital watermark that can be detected when the image is scanned and processed, and another field can contain watermark data which can be correlated to the output of a fingerprint reader or of apparatus which scans a user's iris. The watermarks in the different graphic elements of the document are correlated to each other and correlated to the visual material on the document. Thus, the document can not be forged by replacing one element (such as a picture) with a similar element from another document. An automatic validation system of the present invention reads multiple fields on the document, and it also automatically detects information about the user. The various information is correlated to validate the document.

Abstract: A heat seal connector (100) includes a flexible substrate (105), interconnects (110) disposed thereon, and a parting agent (115) contiguous with the flexible substrate (105) for preventing the heat seal connector (100) from adhering to a heating platen (505) applied thereto, wherein the heating platen (505) does not include a parting agent for preventing the heat seal connector (100) from adhering to the healing platen (505). The heat seal connector (100) is bonded to first and second electronic circuits (415, 420) during application of the heating platen (505) such that the interconnects (110) electrically couple conductive pads (417) formed on the first electronic circuit (415) to corresponding conductive pads (425) formed on the second electronic circuit (420).
