  • Patent number: 7916031
    Abstract: A server component includes a network interface and an analysis component. The server component is at least partially implemented by an operative set of processor executable instructions configured for execution by at least one processor. The network interface is in operative communication with a network and is configured to communicate with at least two nodes of different node types. The network interface is also in operative communication with a local RFID tag attached to a corresponding module. A node of the at least two nodes is a printer-based node associated with a printing machine. The analysis component is configured to utilize the network interface to communicate with the node associated with the printing machine such that the analysis component is in operative communication with the local RFID tag attached to the corresponding module.

  • Patent number: 7859412
    Abstract: A module monitoring system and related method includes a plurality of nodes and a server component. Each node of the plurality of nodes is in operative communication with a network and with at least one RFID attached to a module. Each node of the plurality of nodes is a node type and at least two nodes of the plurality of nodes are different node types. A node of the at least two nodes is a printer-based node and is associated with a printing machine. The node associated with the printing machine is also in operative communication with a local RFID tag attached to a corresponding module. The server component includes a network interface and an analysis component. The network interface is in operative communication with the network and communicates with the at least two nodes utilizing the network.

  • Patent number: 7706030
    Abstract: An apparatus for illuminating a document includes an optical element formed of a light-transmissive material of a predetermined refractory index that defines a curved entry surface and an exit surface opposite the entry surface in which light enters the optical element via the entry surface and light exits the optical element via exit surface. A first substantially parabolic surface is defined between a first edge of the entry surface and first edge of the exit surface and a second substantially parabolic surface is defined between a second edge of the entry surface and a second edge of the exit surface such that the first and second substantially parabolic surface are spaced apart more at the exit surface than at the entry surface.

  • Publication number: 20090314836
    Abstract: A system for automatically tracking documents printed from a printing device includes a database adapted to maintain data corresponding to the identity and location of at least one document. The at least one document has at least one page. A processor is in operative communication with the database to provide a document file containing both a printable content and an RFID taggable content. The processor is configured to provide the printable content to the printing device and the taggable content to an RFID tag writer. The RFID tag writer is adapted to install diagnostic data corresponding to the printing device on at least one of a first RFID tag and a second RFID tag and security data corresponding to the at least one document on at least one of the first and second RFID tags.

  • Patent number: 7518759
    Abstract: In an image sensor having a plurality of photodiodes, subsets of photodiodes share a common node for signals to be sent to an amplifier. Within each subset, each individual photodiode is selected for sending signals to the amplifier by an associated selection device. The selection device is a MOS device operating in a linear region. The subset of photodiodes share a common “fill and spill” or “bucket brigade” transfer circuit to the amplifier, the transfer circuit including at least one MOS device which operates in a subthreshold region.

  • Patent number: 6654058
    Abstract: A set of CMOS-based amplifiers amplify signals from a set of photosensors within a large photosensitive imaging device. When the imaging device reads out image signals, each amplifier is selected for operation only within a brief time window when the particular photosensor associated therewith is reading out. Incidental to reading out a signal through a particular amplifier, all nodes which are capacitively coupled to the input node of the amplifier are biased to a known magnitude. In this way, residual charges remaining in the amplifier from a previous readout will not distort subsequent signals read through the amplifier.

  • Patent number: 6552324
    Abstract: A CMOS-based voltage signal amplifier is particularly useful for amplifying signals from a single photodiode, or a small set of photodiodes, within a large photosensitive imaging device. When the imaging device reads out image signals from a large number of photodiodes, each amplifier is selected for operation only within a very brief time window when the particular photodiode associated therewith is reading out. The amplifier of the present design is suitable for rapid power-up and power-down when it is selected and deselected.
