Abstract: An integrated circuit (IC) chip including clock generation circuitry to generate a clock signal. Clock interface circuitry is coupled to the clock generation circuitry and includes multiple transmit pins that are distributed across a mounting surface of the IC chip. Each of the multiple transmit pins is configured to transmit a respective version of the clock signal to one or more off-chip devices. Multiple receiver pins are distributed across the mounting surface of the IC chip and correspond to the multiple transmit pins. Each of the multiple receiver pins is configured to receive respective arrival clock signals from the one or more off-chip devices. Delay compensation circuitry is coupled to the clock interface circuitry and includes multiple delay circuits. Each delay circuit is configured to delay a given clock signal fed to a given transmit pin by a given delay value to establish global timing alignment of the arrival clock signals at the one or more external devices.

Abstract: Computationally efficient, highly accurate, and cost-effective approach for detection of damage in a structure is described. Methods include a combined analysis in both global and local regions of a structure to predict the received wave signals at a location due to scattering of Lamb waves at a damage site. Through comparison of an actual received wave signal with the predicted signals, identification of damage location and/or type can be provided. Methods can be particularly beneficial when considering damage assessment in a complex structure that includes plate-like structures that include an extension off of a base plate, e.g., a stiffened structure.

Abstract: A technique for discovering and identifying locations at which to deploy new Layer-2 nodes within a telecommunications network. The disclosed technique is intended to identify Layer-2 nodes at locations where they can improve service availability when deployed, especially in geographic regions that suffer frequent or simultaneous cable breaks, or both. The locations of the new Layer-2 nodes depend on the underlying Layer-0 network topology, as well as on the existing Layer-2 topology. Thus, the disclosed technique features a cross-layer approach that takes these factors into account and evaluates the locations in a way that can considerably increase the availability of one or more services offered in the telecommunications network.
