Abstract: A method for load balancing traffic from controller to destination access point (AP) via switch across multiple physical ports starts with controller receiving a packet from a source client device that is destined for destination client device associated with destination AP. The controller may select, based on an identifier associated with source or destination client device, a first or a second controller IP address. Controller may encapsulate the packet to generate an encapsulated packet including an outer header that includes the selected controller IP address. Controller may transmit the encapsulated packet to the switch that may distribute traffic to destination AP across multiple physical ports based on the selected controller IP address. Controller may also select a destination port based on destination client device of a packet and may encapsulate the packet using CAPWAP to generate an encapsulated packet including the destination port in a header of the encapsulated packet.

Abstract: The present disclosure discloses a method and network device for offloading cryptographic functions to support a large number of clients. Specifically, a network device receives a packet corresponding to a client device via an interface, and determines whether a first hardware module that performs cryptographic operations on a per-client basis overflows. If first hardware module overflows, the network device retrieves a cryptographic key for the packet, and sends the received packet with the retrieved cryptographic key to a second hardware module that performs cryptographic operations on a per-packet basis to perform one or more cryptographic operations. If not, the network device sends the packet to the first hardware module to perform the one or more cryptographic operations.

Abstract: A system and method for GPS acquisition in relatively high interference is described. Acquisition is aided by an Advanced Tightly Coupled (ATC) tracking filters that compute a satellite range residuals and range rate residuals for satellites being acquired. Multiple channels are used in parallel to search for the desired satellites. Range residuals from the ATC filters are used to correct the computed receiver offset and thus allow acquisition in the presence of relatively high interference.

Abstract: A system and method for generating a navigation solution in high interference and dynamic environments using Global Positioning System (GPS) and inertial measurement unit (IMU) data is described. The system includes an Advanced Tightly Coupled (ATC) tracking processor for a multi-satellite tracking system. The ATC accepts early, late, and on-time I and Q data from the GPS signal tracker and outputs vehicle-to-satellite range and range rate residual measurements to a navigation Kalman filter. The ATC includes nonlinear discriminators which transform I and Q data into linear residual measurements corrupted by unbiased, additive, and white noise. It also includes an amplitude estimator configured to operate in rapidly changing, high power noise; a measurement noise variance estimator; and a linear residual smoothing filter for input to the navigation filter.

Abstract: A system and method for generating a navigation solution in high interference and dynamic environments using Global Positioning System (GPS) and inertial measurement unit (IMU) data is described. The system configuration is a multi-satellite tracking loop structure obtained by closing each satellite's tracking loop through a single, multi-state navigation filter. This generates a robust navigation solution that can track GPS signals in a lower signal to noise ratio than can the standard GPS tightly coupled tracking loops. The system contains an Advanced Tightly Coupled (ATC) tracking processor which accepts early, late, and on-time I and Q data from the GPS signal tracker and outputs vehicle to satellite range, range rate and range acceleration residual measurements to a navigation Kalman filter. The ATC includes nonlinear discriminators which transform I and Q data into linear residual measurements corrupted by unbiased, additive, and white noise.

Abstract: Using a distributed computer network to support efficient transfer of baggage from inbound aircraft to connecting aircraft. The network comprises a server computer logically connected to databases maintained by the carrier and containing passengers' itineraries and their baggage information. Also connected to the network are dispatch clients, responsible for managing the transfer of baggage, and tug clients, responsible for managing delivery of baggage from the inbound flight to the connecting flights. When an inbound flight is approaching a typical hub airport, a software module operating on the server computer retrieves data for passengers with connecting flights and their baggage. The software module uses this data to evaluate various combinations of assignments and routes for transferring the baggage and determines which is the most efficient solution. The dispatch client then obtains and distributes the assignments and routes to the tug clients.

Abstract: A decorative concho that can be attached to the belt loops of a person's pants to provide a different "look". It consists of a decorative buckle which has three bars attached to the back of the buckle. Two of the bars are attached at the ends of the buckle and at one side of the buckle. The other end of the two bars are free. The third bar is attached between the first two bars and is permanently attached at one end to the buckle. The end that is permanently attached is adjacent the free ends of the other two bars to provide a serpentine path between the bars. The concho can be attached to the belt loops by slipping one bar at a time on the belt loop.
