    Abstract: A computer-implemented system and method for entity tracking and identification is provided. A tracker associated with an entity is tracked. Communication is continuously attempted between the tracker and a tracking device associated with an individual in custody of the entity. During one of the attempted communications, an absence of the tracker is determined by identifying a time of the attempted communication and applying a time threshold to the time for the attempted communication. The absence of the tracker is identified when no communication has been established with the tracking device within the time threshold. The entity is classified as missing when the absence of the tracker is determined.

    Abstract: A sun exposure sensor for disposable or single use including a substrate having an upper surface and a lower surface; a sun exposure sensing portion disposed on the upper surface of the substrate, the sun exposure sensing portion comprising a fluorescent toner image, wherein the fluorescent toner image increasingly fades upon exposure to sunlight; a sun exposure scale disposed on the upper surface of the substrate, the sun exposure scale comprising an evaluation image for evaluating an amount of fading of the fluorescent toner image; an optional coating layer disposed over all or a portion of the upper surface of the substrate; an optional backing layer disposed over all or a portion of the lower surface of the substrate. A process for preparing the sensor using xerographic toner printing.

    CPC classification number: B41J2/16538 ,  B41J2/16544 ,  B41J2/16585

    Abstract: A printhead maintenance system for a printing machine having at least one printhead, the system includes a body, at least one guide track supporting the body for movement along the at least one guide track in proximity to the face of the printhead, and a drive mechanism in engagement with the body and operable to move the body along the guide track. A wiper blade is movably mounted on said body for movement between a retracted position in which the wiper blade cannot contact the face of the printhead and an operative position in which the wiper blade can contact the face of the printhead. A biasing mechanism is provided between the wiper blade and the body that is configured to bias the wiper blade to the operative position. The system includes a retraction mechanism that is operable to move the wiper blade to the retracted position upon movement of the body along the guide track.

    IPC: C08G69/48

    CPC classification number: C08G69/48

    Abstract: Methods for producing a polyamide having an optical absorber pendent from the polyamide's backbone (OAMB-polyamide) may comprise: esterifying a hydroxyl-pendent optical absorber with a halogen-terminal aliphatic acid to yield a halogen-terminal alkyl-optical absorber; and N-alkylating a polyamide with the halogen-terminal alkyl-optical absorber to yield the OAMB-polyamide. Other methods for producing an OAMB-polyamide may comprise: esterifying a carboxyl-pendent optical absorber with a halogen-terminal aliphatic alcohol to yield a halogen-terminal alkyl-optical absorber; and N-alkylating a polyamide with the modified optical absorber to yield a polyamide having the OAMB-polyamide.
