  • Publication number: 20100223234
    Abstract: A content or document management system includes a content or document repository; a dedicated e-mail account; and a mail agent associated with the dedicated e-mail account. The mail agent processes a received e-mail message to determine a sender's identity; authenticates the identity of the sender and an authorization of the sender with respect to the content or document repository; parses, when a sender is authenticated and authorized, document request information from the e-mail message; and either stores a document to or retrieves a document from the content or document repository. The mail agent may authenticate the identity of the sender using a digital signature, or may authenticate the identity of the sender using an e-mail address in a FROM header field of the received e-mail message header. The mail agent may decrypt encrypted messages from the sender, and may sign and encrypt responses to the sender.

  • Patent number: 7617195
    Abstract: In accordance with the disclosure, there is provided a method for identifying duplicate documents comprising drafting a first document and creating a near unique representative string based on the document content. The method further comprises searching for other documents with the same NRS and selectively assigning a duplicate group identification to the first document, the duplicate group identification is unique if no near unique representative string matches are found, or the duplicate group identification is the same as an associated duplicate document's duplicate group identification that matches the NRS. The method further comprises placing the DGI into a meta-data of the first document and recalling a list of duplicates of a particular document based upon user demand by searching the meta-data and selecting documents using the same DGI.

  • Patent number: 7501586
    Abstract: A method and apparatus for improving printed circuit board signal layer transitions are described. In one embodiment, the method includes the formation of a first via within a printed circuit board (PCB). A second via is formed concurrently within the PCB. In one embodiment, the second via is positioned proximate the first via to enable electromagnetic coupling between the first and second vias. Following formation of the second via, the first and second vias are connected to provide a series connection between the first and second vias. In one embodiment, the series connection between the first and second vias reduces a stub length with respect to the first via to reduce and potentially eliminate stub resonance for, for example, short signal layer transitions. Other embodiments are described and claimed.

  • Patent number: 7453950
    Abstract: A method and apparatus to improve modulation efficiency. A symbol is created in which the relative position of a second pulse is a symbol period encode at least one bit. The symbol is transmitted across a communication channel. The one or more bits modulated by the position of the second pulse are recovered such that high bit rate communication may occur without channel compensation.

  • Patent number: 7091813
    Abstract: An integrated circuit transformer. A substrate supporting multiple layers of materials of an integrated circuit is provided with a first metallization layer comprising a first set of turns of a primary winding of a transformer, and a second set of turns of a secondary winding of the transformer. A insulation layer is deposited over the first metallization layer, and a second metallization layer bearing a second set of turns of the primary winding, and an optional third set of turns of a second secondary winding. A via connection connects one end of the first set of turns of the primary winding to the second turns of the primary winding located on the second metallization layer. The result is a transformer structure where the primary winding is provided on multiple layers and each secondary winding is confined to a single layer.
