摘要： 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.

摘要： 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.
