Abstract: Methods and systems for authenticating a user. One system includes a camera and an authentication computer. The authentication computer is configured to receive an image of a user captured by the camera, determine, based on the image, a constraint of the user impacting an availability of a part of the user's body for use in authenticating the user, and determine, based on the constraint of the user, an action to be performed by the user. The authentication computer is also configured to transmit data to a user device worn by the user, the data usable by the user device to output instructions to the user to perform the action, and, in response to detecting the action performed by the user, authenticating the user to use a resource.

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 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: 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.

Abstract: Polyester water-based defoamers are prepared by reaction of a dimer fatty acid, a fatty acid and two different polyalkylene polyols, e.g. polypropylene glycol and polyethylene glycol. The resulting polyesters are readily dispersible in water to form a water-based macroemulsion in the absence of any oil or short chain alcohols. The macroemulsion is an effective defoamer in ground-wood and thermomechanical pulping operations.

Abstract: Polymeric defoamer compositions are prepared from hydroxyalkylacrylate or methacrylate containing polymers which are then solubilized in an organic carrier system. The polymers are effective defoamers and drainage aids for brown stock washers, screen rooms, and in other paper-making operations. The compositions, which may be petroleum oil-free, avoid many of the deleterious effects of conventional petroleum oil-based EBS defoamers.
