Abstract: The disclosed wearable device systems include several features for alerting and guiding persons who are approaching or near to potentially hazardous or high-risk conditions in their nearby environment. Sensor data from wearable devices (also referred to herein as “wearables”) are used to determine the presence of various unsafe environmental conditions and phenomenon, including dangerous terrain or other unusual conditions. The wearable would be used to warn a person, for example via auditory or haptic-based feedback, if the person is about to encounter an unsafe condition. In particular, the proposed systems can be of great benefit to the visually impaired, those persons with physical disabilities, or persons otherwise vulnerable to particular environmental conditions.

Abstract: Hybrid use of dual policies is provided to improve a communication system. In a multiple access scenario, when an inactive user equipment (UE) transitions to an active state, it may be become a burden to a radio cell on which it was previously camping. In some embodiments, hybrid load balancing is provided using a hierarchical machine learning paradigm based on reinforcement learning in which an LSTM generates a goal for one policy influencing cell reselection so that another policy influencing handover over active UEs can be assisted. The communication system as influenced by the policies is modeled as a Markov decision process (MDP). The policies controlling the active UEs and inactive UEs are coupled, and measureable system characteristics are improved. In some embodiments, policy actions depend at least in part on energy saving.

Abstract: A tool comprising a nubbin, or projection, is used to press on a recessed pushbutton of a shaft coupler. In one embodiment, a circular structure or a C shape structure fits a finger of the user's hand. A nubbin extends from the structure exterior. An arch, or a pair of projections, extend transversely to the user finger length, to contact one or both adjacent fingers during use and limit rotation of the tool. Another embodiment comprises a first element and a second element, each comprising two arches connected end-to-end; the two-arch openings face each other. To fit different diameter fingers, the spacing between the two elements is adjustable; a shaft integral with one element slides within a boss that is integral with the other element.

Abstract: A computer-implemented method causes data processing hardware to perform operations for training a firewall utilization model. The operations include receiving firewall utilization data for firewall connection requests during a utilization period. The firewall utilization data includes hit counts for each sub-rule associated with at least one firewall rule. The operations also include generating training data based on the firewall utilization data. The training data includes unused sub-rules corresponding to sub-rules having no hits during the utilization period and hit sub-rules corresponding to sub-rules having more than zero hits during the utilization period. The operations also include training a firewall utilization model on the training data. The operations further include, for each sub-rule associated with the at least one firewall rule, determining a corresponding sub-rule utilization probability indicating a likelihood the sub-rule will be used for a future connection request.

Abstract: A URL velocity monitor is integrated with a message-hold decision maker of an electronic mail processing system that processes electronic messages for a protected computer network. The URL velocity monitor receives or obtains a URL, decomposes the URL into URL features based on logical boundaries, and determines features of interest from the URL features for velocity tracking. Examples of URL features can include a randomized URL segment. The velocity of each feature of interest is tracked over a period of time using a counting algorithm that employs a slow counter or a fast counter. The two different counters track two types of velocities which represent different domain behaviors targeting the protected computer network. The URL velocity monitor determines whether the velocity of a feature of interest is accelerating within the time period. If so, the URL is placed in a queue or a sandbox.

Abstract: A message-hold decision maker system used with an electronic mail processing system that processes electronic messages for a protected computer network improves the electronic mail processing system’s performance by increasing the throughput performance of the system. The improvements are achieved by providing an electronic mail processing gateway with additional logic that makes fast and intelligent decisions on whether to hold, block, allow, or sandbox electronic messages in view of potential threats such as viruses or URL-based threats. A message hold decision maker uses current and stored information from a plurality of specialized classification engines to quickly make the decisions. In some examples, the message hold decision maker will instruct an email gateway to hold an electronic mail message while the classification engines perform further analysis.
