Abstract: Embodiments of the disclosure provide a system for operating a radio frequency (RF) network having a plurality of communication nodes. A network transceiver communicates with communication nodes in the RF network. A computing device coupled to the network transceiver performs actions including: evaluating a state of the RF network using a machine learning model, based on a spectrum environment and a communication objective, generating a set of communication parameters based on the state of the RF network, causing the network transceiver to communicate with the a communication node using the generated set of communication parameters, and modifying the machine learning model based on a result of causing the network transceiver to communicate with the communication node.

Abstract: Methods and systems for controlling dynamic spectrum access (DSA) for the purposes of wirelessly communicating or exchanging data within a network environment are disclosed. Methods may include detecting, via at least one asset included in a wireless device network, at least one candidate asset attempting to enter the wireless device network from an external network, and constructing a spectrum profile for the wireless device network based on metadata for transactions between assets in the wireless device network. The method may also include applying an access policy including the spectrum profile to the at least one candidate asset within the wireless device network, and admitting the at least one candidate asset to the wireless device network in response to applying the access policy to the at least one candidate asset.

Abstract: Embodiments of the disclosure provide a transmission system, including: an encoder for encoding a set of information symbols into a set of encoded signals for transmission, wherein the encoder applies a full-diversity space-time block code (STBC) to the set of information symbols; and at least three antennas for transmitting the set of encoded signals over four epochs at a code rate of two.

Abstract: Embodiments herein provide a method for admitting devices to a special access frequency band of a wireless communication network, including: detecting an access request to communicate via the network, the network including at least one priority device communicating via the special access frequency band of the network, wherein the access request is generated by a non-priority device; evaluating whether a portion of the special access frequency band of the network is available for use by the non-priority device, based on communication settings of the non-priority device; transmitting a governing instruction to the non-priority device in response to the portion of the special access frequency band of the network being available for use by the non-priority device; and denying the access request in response to the portion of the special access frequency band of the network not being available for use by the non-priority device.

Abstract: An apparatus and method for providing a protocol stack design which resists active jammers. The apparatus including a transmitter component, the transmitter component including: a rate-2 orthogonal space-time block code (OSTBC) encoder for processing a set of information symbols to produce a set of encoded signals; a precoder module coupled to an output of the rate-2 OSTBC encoder for modifying a signal-to-jammer plus noise ratio (SJNR) of the set of encoded signals; and an eigen-beamformer module coupled to an output of the precoder module, and configured to generate a set of symbols for transmission via a set of eigenmodes of a channel covariance matrix for the transceiver.

Abstract: A vertebral assist device for monitoring, supporting, stabilizing, and adjusting vertebrae. An embodiment of the vertebral assist device includes: a plurality of vertebral support sections, each of the plurality of vertebral support sections configured to support a respective vertebra of a patient; an actuating system for interconnecting each adjacent pair of the plurality of vertebral support sections, the actuating system dynamically controlling an alignment of the plurality of vertebral support sections; and a control system for actively monitoring the alignment of the plurality of vertebral support sections and for directing the actuating system to dynamically adjust the alignment of the plurality of vertebral support sections until an alignment goal is achieved.

Abstract: Embodiments of the present disclosure relate to routing data through a distributed communications network (DCN) including several communication devices. Each communication device may include or be in communication with a computing device which causes the communication device to perform actions including: calculate a utility score for a subset of the plurality of communication devices, the utility score quantifying transmissibility of a data packet from the transceiver assembly to another communication device. The utility score may be calculated based on: a distance between the transceiver assembly and the communication device, a transmission queue at the transceiver assembly, a remaining life of the power source, a power consumption to transmit the data packet to the communication device, and a data throughput of the communication device. The computing device may generate instructions to transmit the data packet to at least one communication device in the subset, based on the calculated utility score.
