  • Patent number: 8352829
    Abstract: Techniques relate to the regeneration of a cyclical redundancy check (CRC) value of a data packet in a manner that avoids a complete CRC recomputation based on the entire packet after only a portion of a packet has been modified. When modifying and forwarding a packet, a network device identifies only the changed portions of a packet and computes an updated CRC for the packet based on the original CRC, the modified portions, and the length from the modified field to end of packet.

  • Patent number: 8347207
    Abstract: Techniques are described for sharing multidimensional data and associated annotations between software systems. As described herein, the techniques provide mechanisms for defining inter-application “links” for automatically copying data and associated annotations among databases associated with the enterprise software systems. For example, a system may include a first database storing multidimensional data for a first software application, and a second database storing multidimensional data for a second software application. The system further includes an interface by which an administrator defines a link that specifies a source area of the first database and a target area of the second database. A link control module automatically moves multidimensional data and annotations associated with cells or cubes of the multidimensional data from the source area to the target area in accordance with the link.

The network interface device transmits and receives information, such as voice, video and data, to and from the UPS unit via the second power line. The UPS unit receives the information transmitted by the network interface device via the second power line, and transmits the received information to subscriber devices within the premises via the first power line. The UPS unit receives information transmitted by subscriber devices via the first power line, and transmits the received information to the network interface device via the second power line. The first and second power lines each serve as both a power line and a communication medium.

  • Patent number: 8340779
    Abstract: In general, the invention is directed to a technique for percutaneously introducing a stimulation lead into a target stimulation site via the epidural region proximate the spine of a patient. The process of introducing the stimulation lead may include the use of a hollow stimulation lead introducer, which comprises an elongated sheath and an elongated dilator. The dilator fits within the sheath and serves to widen a path through the epidural region for the introduction of a stimulation lead. At least a portion of the stimulation lead introducer has an oblong cross-section, allowing passage of stimulation leads such as paddle leads. The stimulation lead introducer may enter the epidural region proximate a spine of a patient via a guidewire. The stimulation lead introducer provides a path through the epidural region of a patient to a target stimulation site. A stimulation lead may travel through the path to reach the target stimulation site where it may provide therapy to the patient.

  • Patent number: 8335568
    Abstract: A medical device, such as an implantable medical device (IMD), determines values for one or more metrics that indicate the quality of a patient's sleep, and controls delivery of a therapy based on the sleep quality metric values. For example, the medical device may compare a sleep quality metric value with one or more threshold values, and adjust the therapy based on the comparison. In some embodiments, the medical device adjusts the intensity of therapy based on the comparison, e.g., increases the therapy intensity when the comparison indicates that the patient's sleep quality is poor. In some embodiments, the medical device automatically selects one of a plurality of therapy parameter set available for use in delivering therapy based on a comparison sleep quality metric values associated with respective therapy parameter sets within the plurality of available therapy parameter sets.
