  • Patent number: 7958187
    Abstract: The present invention provides an electronic message management system (EMS) that includes a real-time feedback loop where data is collected from the electronic messages on incoming connection attempts, outgoing delivery attempts, and message content analysis, and written to a centralized data matrix. A separate process accesses the data matrix and analyzes trends in that data. The detected data patterns, trends or behavior is based on configuration parameters for the recipient. Based on these determinations, the process is able to instruct components in the EMS to accept, redirect, refuse, modify, defer, or otherwise dispose of the connection request, the delivery attempt, or the message. Associated methods for managing the transmission of electronic messages are also disclosed.

  • Patent number: 7952213
    Abstract: An overlay mark arrangement for reducing the asymmetric profile and an overlay shift during an integrated circuit manufacturing process is disclosed. In one embodiment, the overlay mark arrangement may comprise a first mark, a second mark and a stress releasing means. The first mark is used to indicate the position of a lower layer, the second mark is used to indicate the position of an upper layer; and the stress releasing means is used to release the film stress induced by the upper layer. Unlike the conventional overlay mark arrangements, which will have a severe overlay mark shift due to the film stress, the asymmetric overlay mark profile can be improved by using multiple trenches around the overlay marks according to certain embodiments of the invention disclosed herein.

  • Patent number: 7954108
    Abstract: An HDL description of a communications protocol machine for transforming object communications into low-level octet sequences for physical transport is synthesized onto a programmable logic device such as an FPGA. This communications protocol machine replaces traditional software-based inter-ORB protocol engines in distributed computing environments, including embedded environments, to provide reduced latency. The communications protocol machine is described with two distinct elements: a protocol messaging machine and an encoder/decoder. The protocol messaging machine converts an object communication into a low-level octet sequence comprising one or more inter-ORB protocol messages and converts a low-level octet sequence comprising an inter-ORB protocol message into an object communication.
