Abstract: An outbound packet is detected from a client device of a first spoke destined to a client device of a second spoke over SD-WAN through a hub connecting the first and second spokes with IPSec tunneling. The first spoke is on a local enterprise network, the second spoke is on a remote enterprise network and the hub is on wide area network, and each of the first spoke, the second spoke and the hub are each ADVPN2.0 compatible. Responsive to the detection, a health check is performed on the remote spoke. A path is selected between a local NAT device of multiple NAT devices of the first spoke and a remote NAT device of the multiple remote NAT devices of the second spoke, based on link quality data of the response. A NAT hole is punched between a selected local NAT and a selected inbound NAT and an IPSec tunnel is established, independent of the hub.

Abstract: A local spoke is configured with a hub that serves at least one remote spoke equipped with a plurality of IPSEC endpoint interfaces for routing traffic according to a routing table of the hub. A first routing path is received to the at least one remote spoke for dynamic VPN with a first IPSEC endpoint selected by the hub based on a Reply message without consideration of first link quality of the remote spoke relative to other available links. In another embodiment, an ADVPN shortcut is established. Data packets are then transmitted using a second routing path for dynamic VPN with a second IPSEC endpoint. A new ADVPN shortcut is established for more optimal routing, based on updated link quality metrics discovered during a health check. The existing ADVPN shortcut is then allowed to expire.

Abstract: Circuits and methods for determining a maximum bias for computing softmax on a tensor include a processor circuit configured to transform in parallel, elements of each group of a plurality of groups of elements of a tensor X into respective power-of-two elements. The respective power-of-two element from element xt of the tensor is pt, pt=(xt*log2e), and pt has an integer part and a fraction part. A first comparison circuit (204) is configured to determine respective group-level biases for the groups. The group-level bias of groupm is dm, and dm is an integer part of a maximum of the power-of-two elements of groupm. A second comparison circuit is configured to determine a greatest one of the respective group-level biases to be a tensor-level bias, dmax.

Abstract: A soft, flexible microtube sensor and associated method of sensing force are described. A liquid metallic alloy is sealed within a microtube as thin as a strand of human hair to form the physical force sensing mechanism. The sensor is hardly distinguishable with the naked eye, and can be used for the continuous biomonitoring of physiological signals, such as unobtrusive pulse monitoring. Also described is a method of fabricating the microtube sensor and wearable devices incorporating one or more microtube sensors.

Abstract: The present invention relates to a flexible polymer-based microtube having an inner diameter of about 4 ?m to about 1000 ?m and a variable outer diameter, wherein the cross-sectional shape of the microtube can be, for instance, circular, rectangular, square, triangular, elliptical, star or irregular. The present invention also relates to a method of making the flexible microtube and devices incorporating the flexible microtube.
