Systems and methods for document verification

A method for issuing a credential includes scanning in documents (e.g., breeder or ID documents) used to verify the applicant of the credential and creating data records including the image of the documents. As a means to reduce fraud, these data records are linked to the credential and to the issuer location, operator and time and place of issuance. If the document includes machine readable information, the method automatically reads the machine readable information from the document and uses at least part of the machine readable information from the document to pre-populate a form used to create a credential, such as an identification document. The method includes applying a transformation to the image of the document that enables protection against fraudulent use. The transformation secures the image of the document from tampering and / or enables tracking of the use of the document image to deter fraud. A method of verifying a credential comprises reading a physical security feature attribute on the credential, reading a logical attribute on the credential, and comparing information from the physical security feature with the logical storage element on the credential to verify the credential.

A light-transmitting surface is formed on the outer side of the cap body, and the light reflected by the reflective surface is projected onto the light-transmitting surface to exit the cap body. Thus, the light is emitted towards the lateral of the lens cap along a horizontal direction.

Increasing fill-factor on pixelated sensors

Disclosed are systems, devices, and methodologies that facilitate increasing the effective fill-factor of digital sensors. In general, fill-factor relates to the active area or photosensor region of the sensor with respect to the inactive area / deadzone or space between pixels. By increasing the effective fill-factor, transmission of optical information is increased to the sensor while mitigating information loss between pixels. A digital camera may contain a sensor that is responsive to electromagnetic radiation and a coherent scattering medium between the sensor and a lens that diffuses the electromagnetic radiation with respect to the sensor in order to increase the effective fill-factor.

Self-aligned last-metal C4 interconnection layer for Cu technologies

A controlled collapse chip connection (C4) structure having stronger resistance to failure is constructed for use with integrated circuit devices having copper wiring. Failure resistance is obtained by replacing the mechanically weak final passivation to copper interface. The weak interface is eliminated by use of a specific peg on peg structure together with a layer of shunt metal having excellent adhesion and barrier characteristics. A shunt metal, e.g., Ta or TaN, is placed between both the copper and final passivation and the copper and C4 metals such that it overlaps the edge of the peg defined wiring mesh to encase the copper. Overlap is obtained by the peg on peg structure where a SiO2 peg defines the copper wire mesh and a smaller Si3N4 peg placed on the SiO2 peg defines the overlap above the mesh wire and provides the ability to pattern the overlayer shunt without exposure of the copper conductor.
