Abstract: Various embodiments are disclosed for increasing Layer-3 LPM (longest prefix match) routing database in a network platform. In some embodiments, chipsets in fabric modules (FMs) can be partitioned into multiple banks. Network traffic can be directed towards a corresponding bank in the FMs by using a LPM table on a line card (LC). Entries in the LPM table on the LC can be programmed either statically or dynamically based upon LPM routes that are dynamically learned.

Abstract: Disclosed are systems, methods, and computer-readable storage media for synchronizing the secondary vPC node to the primary vPC node in a BFD protocol over a VxLAN channel with a remote node. In some embodiments of the present technology a primary vPC node can receive a packet from the remote node. The primary vPC node can then determine the packet includes either a MAC address corresponding to the primary vPC node or a secondary vPC node, and at least one inner packet identifier. Additionally, the primary networking switch can identify an access control list (ACL) entry from a set of ACL entries based on the at least one inner packet identifier. Subsequently, based on the ACL entry, the primary vPC node can generate a copy of the packet. After which, the primary vPC node can transmit the packet to the secondary vPC node.

Abstract: A plurality of line cards with each line card having a respective network forwarding engine and a respective outgoing interface (OIF) list and at least one fabric module communicatively coupled with each line card with each fabric module can have a respective network forwarding engine. The local OIF list can be asymmetrically programmed. The network forwarding engine of a line card can be configured to receive a multicast packet, compare a multicast address associate with the received multicast packet with entries in the local OIF list of the line card and forward the received multicast packet to at least one interface associated with the multicast address in response to the comparison resulting in a match.

Abstract: In one embodiment an approach is provided to efficiently program routes on line cards and fabric modules in a modular router to avoid hot spots and thus avoid undesirable packet loss. Each fabric module includes two separate processors or application specific integrated circuits (ASICs). In another embodiment, each fabric module processor is replaced by a pair of fabric module processors arranged in series with each other, and each processor is responsible for routing only, e.g., IPv4 or IPv6 traffic. The pair of fabric module processors communicates with one another via a trunk line and any packet received at either one of the pair is passed to the other of the pair before being passed back to a line card.

Abstract: System and method for non-contact acquisition of current physiological data representing a subject. A first electromagnetic wave representing current physiological status of a first subject is modified by a second electromagnetic wave representing current physiological status of a second subject in proximity to the first subject. A parameter of the first electromagnetic wave representing a first physiological status of a first subject is measured with electronic circuitry to extract a parameter of the second electromagnetic wave. Historical physiological data associated with the second subject is acquired. The current physiological data representing current physiological status of the second subject is then derived based on historical physiological data of the second subject and a comparison between the first and second parameters.

Abstract: A heterogeneous multiple core control system for predictive medical monitoring is provided. The system includes a first processor platform that is optimized for serialized computation and a second processor platform that is optimized for parallelized computation. A memory stores instructions that are executed by either the first processor platform or the second processor platform to provide the functionality of the system. By executing the instructions, the system determines whether a condition of a first patient is to be monitored using a primarily parallelized model or a primarily serialized model. The predicted condition is calculated using the primarily parallelized model by executing the primarily parallelized model on the second processor platform. The predicted condition is calculated using the primarily serialized model by executing the primarily serialized model on the first processor platform.

Abstract: Systems and methods are described for automatically identifying a food item. A color image and a thermal image are received by an electronic processor with a first food item in the field of view of both the color image and the thermal image. The electronic processor identifies a region of pixels in the color image that corresponds to the first food item based at least in part on a temperature intensity of the pixels in the identified region of pixels relative to other pixels in the thermal image. At least one feature is extracted from the identified region of pixels in the color image corresponding to the first food item and the electronic processor automatically identifies a type of food corresponding to the first food item based at least in part on the at least extracted feature.

Abstract: Systems and methods are provided for encoding and decoding data (such as, for example, an encryption key) using a physiological signal. A data item string is separated into a defined number of component segments and each component segment is used as a coefficient of a polynomial equation. A plurality of signal features are then identified from a physiological signal and a plurality of ordered pairs are created based on the plurality of identified signal features using the polynomial equation. A data package including the plurality of ordered pairs and obfuscated by a plurality of chaff points is transmitted to another system. The receiver system uses a corresponding physiological signal to filter out the chaff points and to reconstruct the polynomial equation, for example, by LaGrangian interpolation. The coefficients of the reconstructed polynomial equation are then used to derive the encoded data item string.
