Abstract: An asynchronous medium access control layer scheduler increases efficiency for directional mesh networks by removing extra overhead in the time slots. The efficiency is increased by dividing time slots into sub-slots to allow for a receiving node to be offset by at least one sub-slot from the transmitting node. This enables the scheduler to more efficiently schedule operations for the nodes so that nodes can be performing other functions rather than waiting to receive a transmission or waiting after transmitting a transmission. The sub-slots may be sized to approximate the transmission propagation time or time of flight delay.

Abstract: A set of methods for discovery of nodes where at least some of the nodes use directional antennas is presented. The methods consist primarily of partitioning the search space into tiers based on elevation angles and adjusting parameters used to construct tiling patterns and slots for discovery messaging, and search methods patterns. The methods further include partitioning into subslots as well as characterization of HAIL slots and rendezvous slots. The HAIL slots and rendezvous slots are allocated within a search schedule and synched across multiple platforms for greater efficiency of communication.

The methods allow for a period of time of incubation of the pharmaceutical preparation in the resin that effectively removes preservatives, while at the same time maintaining the required amount or concentration of active compound in the preparation. Also provided herein are devices, systems, and methods for the controlled release of anti-inflammatory agents in an insulin infusion set.

Abstract: A system and method of cognitive radio control to allow for low probability of detection and/or low probability of exploitation communications in a contested or hostile environment.

Abstract: A wideband chaotic waveform that is rateless in that it may be modulated at virtually any rate and has a minimum of features introduced into the waveform. Further, the waveform provided may be operated below a signal to noise ratio wall to further enhance the LPD and LPE aspects, thereof. Additionally, the present disclosure may provide a mix of coherent and non-coherent processing techniques applied to signal samples to efficiently achieve coarse synchronization with a waveform that is faster, more efficient and more accurate than using time domain signal correlators alone.

Abstract: The system and method for position, navigation, and timing and more particularly to a system that is time and/or position independent and capable of autonomous transition from GPS to non-GPS navigation. The integrated position, navigation, and timing system uses primary and secondary navigation sensors and primary and secondary navigation measurement sources with a common time reference architecture, an integrated “dual-grid” navigation module, an integrated “dual-grid” navigation Kalman filter, and an integrated “dual-grid” navigation source selection module to provide both geodetic and relative grid timing and/or location among members of a network of platforms, particularly in GPS denied or degraded environments.

Abstract: A digital or smart array antenna has at least one radio and a processor coupled to each antenna element. The processor is coupled with programmable logic that demodulates a plurality of signals received at one antenna element to obtain demodulation symbols. After obtaining the demodulation symbols, the programmable logic applies a weighting function. In this order or sequence, the digital array antenna is able to reduce the processing requirements associating within the signal information. The reduced processing requirements enable the signal information to be shared with adjacent antenna elements that may be timing adjusted between adjacent elements. Then, the sharing continues across all elements the array until the signal reaches an edge of the array. At the edge of the array, a signal beam may be generated that is steer in response to the processed signal information shared between all the elements in the array.

Abstract: The present disclosure relates generally to a network system having multiple users, multiple inputs, and multiple outputs to transmit data from a data source through a link to a data sink. One example of a Multi-user multiple input multiple output (MU-MIMO) system relates to the use of primary transceivers and secondary transceivers in respective networks that effectuate data transmission. The primary transceivers are coupled with a data source and broadcast or transmit the data source signal to a plurality of secondary transceivers in a local area network. The signal is then transmitted over a long link to another set of secondary transceivers that then pass the signal to another primary transceiver. This another primary transceiver is coupled with the data sink to effectuate signal transmission to the data sink. The data is synchronized in manner that requires minimal processing and does not require closed loop phase control.

Abstract: A spectrum sharing system includes an advanced beacon (e.g. a low latency RF link) as part of an information sharing subsystem. The advanced beacon signal carries radar spectrum transmission schedule in an obfuscated way such as not to reveal the geolocation of the radar. The information sharing subsystem directs nodes, such as cell phones, to share spectrum based on spectrum sharing instructions contained in the advanced beacon. The spectrum sharing system permits out-of-band sharing of spectrum white space, as well as sharing of in-band spectrum gray space.

Abstract: A method and a system of managing a policy managed system that includes a policy managed element. The method restricts the policy managed element so that internal configurations and actions of the policy managed element do not violate any policy rules generated external to the policy managed element. The method also prevents the policy managed element from generating policy that exit the policy managed element. The method, at a policy executive element (PEE) located remote from the policy managed element, restricts internal configurations and actions of the PEE so that the PEE does not violate any policy rules generated external to the PEE. The PEE includes a policy generation point (PGP) that the method allows to generate new policy rules that do not violate any existing policy and provides the new policy rules to the policy managed element.
