Abstract: Embodiments are provided for detecting overlapping topics in a messaging system. In an example system, a plurality of trigger phrases is received, where each trigger phrase is configured to trigger a bot that receives the trigger phrase to select a corresponding topic for conversation. For each trigger phrase, a vector representation is generated. Measures of similarity are generated based at least on the vector representations, where each measure of similarity represents a degree of similarity between a respective pair of vector representations. A topic overlap is detected based on a pair of vector representations having a measure of similarity above a similarity threshold, where the topic overlap indicates two trigger phrases that are overlapping. The topic overlap is provided to an authoring tool that comprises one or more interactive elements to enable a user to change at least one of the two trigger phrases that are overlapping.

Abstract: A method for redundant communication at a network gateway includes (1) exchanging data packets with a network application via a first access communication interface, (2) exchanging data packets with customer premises equipment (CPE) via a local communication interface, and (3) in response to occurrence of a first event, exchanging at least some data packets with the network application via a second access communication interface that is different from the first access communication interface.

Abstract: Techniques are described herein that are capable of generating a content signature of a textual communication using OCR and text processing. The textual communication is rendered. Text is extracted from the rendered textual communication using OCR. Customization is removed from the text to provide a templatized version of the rendered textual communication that includes de-customized text. The de-customized text is parsed into tokens. Each token includes a respective subset of a plurality of characters. The tokens are converted into respective numbers. Each number is processed using fuzzy hash functions to provide respective hash values associated with the respective token. Representative hash values are selected for the respective fuzzy hash functions by selecting each representative hash value from the hash values that are processed using the respective fuzzy hash function.

Abstract: Systems, methods, and devices disclosed herein contemplate client updates to traffic filter tables that control delivery of network traffic from an access point to the client over a multi channel wireless network. The client may update the traffic filter table whenever: (i) an application on the client initiates the request; (ii) an application matching a secondary channel requirement in a look-up table is opened or closed; (iii) data characteristics matching the secondary channel requirement in the look-up table are detected or removed; (iv) data usage of the client meets or exceeds a predetermined threshold; (v) data usage of the client falls below a predetermined threshold; and/or (vi) a specified period of time has passed.

Abstract: According to examples, an apparatus may include a processor may identify features in a plurality of data items, determine similarities and/or patterns in the identified features, and group the plurality of data items into a plurality of clusters of data items based on the determined similarities and/or patterns in the identified features in the plurality of data items. The processor may also evaluate the plurality of clusters to identify a potentially malicious pattern among the data items in the plurality of clusters. In addition, the processor may, based on a potentially malicious pattern being identified in a generated cluster of the generated clusters, execute an action with regard to the data items in the generated cluster.

Abstract: Systems and methods implement multi-channel communication by remapping Ethernet frames. An Ethernet frame is captured leaving a first bridge of an Ethernet switch. A destination address of the Ethernet frame is matched to a remap rule and to a filter defined for the remap rule. The destination address of the Ethernet frame is updated based upon the remap rule, and the Ethernet frame is output to an Ethernet port corresponding to the updated destination address of the Ethernet frame. The remap rule and the filter allow the Ethernet switch to route traffic at an OSI model layer-4 level.

Abstract: Mitigating noise in a network is contemplated, such as but not necessarily limited to mitigating noise through a detection process whereby noise deviations resulting from selectively controlling smart taps, switches or other devices to block signaling in the network may be used to locate sources of noise.

Abstract: This disclosure describes a firearm attachment and apparatus for more effectively dry-firing a firearm device during marksmanship training. The firearm attachment includes a coupling portion that is configured to fixedly couple the firearm attachment to a slidable member (e.g., a slide of a pistol or a charging handle of a rifle) of the firearm device, and a tethering aperture that is positioned at a distal end of firearm attachment, relative to the coupling portion. When the firearm attachment is coupled to the firearm device via the coupling portion, and a rearward force is applied at the tethering aperture, the firearm attachment pulls the slidable member of the firearm device into a set position for dry-firing the firearm device. The rearward force can be applied by a sling apparatus that attaches to or through the tethering aperture of the firearm attachment.

Abstract: A variable area flow meter has a magnet carried by a piston which is moved to a position representing fluid flow. An array of magnetoresistive bridge sensors adjacent the path of magnet movement senses the magnet position. The bridges are unbalanced by the magnet field. The analog unbalance signals are read and processed in digital form to develop a flow signal. The flow meter circuits are powered from a 4–20 MA current loop or a remote power supply. Each bridge sensor is powered only when the bridge unbalance signal is being read, to minimize the power requirement.
