  • Publication number: 20200304301
    Abstract: A system and method provide efficient, secure, and highly reliable authentication for transaction processing and/or access control applications. A personal digital key (PDK) is programmed using a trusted programming device to initialize and/or register the PDK for use. In one embodiment, the initialization and registration processes are administered by a specialized trusted Notary to ensure the processes follow defined security procedures. In a biometric initialization, the programming device acquires a biometric input from a user and writes the biometric data to a tamperproof memory in the PDK. In registration, the Programmer communicates to one or more remote registries to create or update entries associated with the user PDK. Once initialized and registered, the PDK can be used for various levels of secure authentication processes.

  • Patent number: 10778925
    Abstract: A multiple-column-per-channel image CCD sensor utilizes a multiple-column-per-channel readout circuit including connected transfer gates that alternately transfer pixel data (charges) from a group of adjacent pixel columns to a shared output circuit at high speed with low noise. Charges transferred along the adjacent pixel columns at a line clock rate are alternately passed by the transfer gates to a summing gate that is operated at multiple times the line clock rate to pass the image charges to the shared output circuit. A symmetrical fork-shaped diffusion is utilized in one embodiment to merge the image charges from the group of related pixel columns. A method of driving the multiple-column-per-channel CCD sensor with line clock synchronization is also described. A method of inspecting a sample using the multiple-column-per-channel CCD sensor is also described.

  • Patent number: 10770189
    Abstract: Control rod drives include linearly-moveable control elements inside an isolation barrier. Control rod drives move the control element through a motor and rotor powering a linear screw internal to an isolation barrier. Induction coils may generate magnetic fields and be moveable across a full stroke length of the control element in the reactor. The magnetic fields hold closed a releasable latch to disconnect the control elements from the linear drives. A control rod assembly may join to the control element. The control rod assembly may lock with magnetic overtravel latches inside the isolation barrier to maintain an overtravel position. Overtravel release coils outside the isolation barrier may release the latches to leave the overtravel position. Operation includes moving the magnetic fields and releasable latch together on opposite sides of an isolation barrier to drive the control element to desired insertion points, including full insertion by gravity following de-energization.

  • Patent number: 10769939
    Abstract: A personal digital key (e.g., which can be carried by a human) contains a memory having different service blocks. Each service block is accessible by a corresponding service block access key. As the personal digital key (PDK) moves around, it is detected by sensors. The sensors report position data, thus enabling location tracking of the PDK. The sensors also provide a data path to various applications. An application that has access to a service block access key can therefore access the corresponding service block on the PDK. The sensors themselves may also contain service block access keys.

  • Patent number: 10764527
    Abstract: A dual-column-parallel image CCD sensor utilizes a dual-column-parallel readout circuit including two pairs of cross-connected transfer gates to alternately transfer pixel data (charges) from a pair of adjacent pixel columns to a shared output circuit at high speed with low noise. Charges transferred along the two adjacent pixel columns at a line clock rate are alternately passed by the transfer gates to a summing gate that is operated at twice the line clock rate to pass the image charges to the shared output circuit. A symmetrical Y-shaped diffusion is utilized in one embodiment to merge the image charges from the two pixel columns. A method of driving the dual-column-parallel CCD sensor with line clock synchronization is also described. A method of inspecting a sample using the dual-column-parallel CCD sensor is also described.

  • Publication number: 20200241422
    Abstract: A system is for processing a photosensitive flexographic printing plate having a latent image formed by image-wise exposure of an aqueous-processable photopolymer. The system can use a first aqueous processing solution with the latent image for cleaning and then washing a resulting relief image with a second aqueous processing solution, where the second aqueous processing solution is devoid of the photopolymer. A processing solution tank is configured to combine the first used aqueous processing solution with the second used aqueous processing solution to form a combined used aqueous processing solution. A processing solution removal can include: a holding tank configured for receiving the combined used aqueous processing solution; and a conduit from the processing solution tank to the holding tank. The processing solution tank includes the combined used aqueous processing solution at less than a predefined maximum volume and having the photopolymer at less than a predefined maximum concentration.

  • Publication number: 20200194476
    Abstract: An image sensor utilizes a pure boron layer and a second epitaxial layer having a p-type dopant concentration gradient to enhance sensing DUV, VUV or EUV radiation. Sensing (circuit) elements and associated metal interconnects are fabricated on an upper surface of a first epitaxial layer, then the second epitaxial layer is formed on a lower surface of the first epitaxial layer, and then a pure boron layer is formed on the second epitaxial layer. The p-type dopant concentration gradient is generated by systematically increasing a concentration of p-type dopant in the gas used during deposition/growth of the second epitaxial layer such that a lowest p-type dopant concentration of the second epitaxial layer occurs immediately adjacent to the interface with the first epitaxial layer, and such that a highest p-type dopant concentration of the second epitaxial layer occurs immediately adjacent to the interface with pure boron layer.

The resultant pitch can have a micro carbon residue (MCR) of 50 wt % or greater, a solubility in toluene of 95 wt % or greater, and a softening point of 200° C. or less. The pitch can optionally be fluxed with a fluxing solvent.

  • Patent number: 10662676
    Abstract: A vehicle includes a vehicle body that defines an opening, a vehicle door that is movable between a closed position and an open position with respect to the opening, a first surface, and a second surface. The first surface is defined on one of the vehicle body and the door and the second surface is defined on the other of the vehicle body and the door. A first latch portion is concealed behind the first surface. A second latch portion is concealed behind the second surface in an unlatched position and is movable to a latched position in which the second latch portion extends into the first latch portion and engages the first latch portion. A locking structure restrains disengagement of the second latch portion from the first latch portion in the latched position.

  • Patent number: 10642157
    Abstract: A method for processing a photosensitive flexographic printing plate having an aqueous-processable photopolymer. A main processing unit is used to develop a relief image by removing unexposed photopolymer using an aqueous processing solution including a first dispersing agent while the photosensitive flexographic printing plate is being subjected to mechanical cleaning. Used aqueous processing solution containing the removed photopolymer is returned back into a processing solution tank. A secondary processing unit is used to wash the developed relief image with secondary aqueous processing solution including a second dispersing agent to remove debris from the developed relief image. Used secondary aqueous processing solution containing the removed photopolymer is directed into the processing solution tank. A portion of the aqueous processing solution from the processing solution tank is removed to keep a volume of aqueous processing solution in the processing solution tank below a predefined maximum volume.
