Abstract: A device for sealing an aperture in a tissue includes: a foot including a distal portion configured to be disposed distal to the tissue when the device is implanted in a position to seal the aperture; and a flexible wing positionable against a distal surface of the tissue adjacent the aperture such that the flexible wing is disposed between the distal portion of the foot and the distal surface adjacent the aperture.

Abstract: Systems, methods, and processor-readable storage media for AI-assisted electrical power grid fault analysis predict the cause of a fault and cause the fault to be remedied by receiving an indication that a first fault has occurred, identifying a plurality of additional fault records associated with the first fault, obtaining a first prediction of the cause of the fault based on the first fault record and the plurality of fault records by applying the fault records to a machine learning model, obtaining a second prediction of the cause of the fault by applying the fault records to a rules-based model, and obtaining a final prediction of the cause of the first fault based on the first prediction and the second prediction. The final prediction of the cause of the first fault is used to cause the predicted cause of the first fault to be remedied.

Abstract: A network timing view provides enhanced visualization for synch timing in support of mobile (4G/5G deployments) and others requiring sync. It allows network managers to view relevant synch data both textually and graphically displayed on the network map nodes and links in a unified view. The user is able to select the appropriate filter on the network map to show the 1588/SyncE connectivity and relevant nodes that are participating in delivering timing. It allows a user to trace the timing path from any timing device upstream to the clock source. It also allows the user to interactively discover and navigate downstream timing paths from any timing device, similar to exploring a tree hierarchy. The timing topology and path data provided allows a user to investigate the timing network for troubleshooting purposes such as timing alarms and events, sync problems, clock quality levels and clock states.

Abstract: Systems, methods, and processor-readable storage media for AI continued learning in electrical power grid fault analysis use historical fault record data to generate a fault cause prediction model for predicting the cause of a fault, and modify the fault cause prediction model based on additional technician data received from power grid technicians. The systems disclosed herein additionally receive an indication of a fault which has occurred in a power grid, obtain a prediction of the cause of the fault by applying the indication of the fault to the fault cause prediction model, and cause the predicted cause of the fault to be remedied.

Abstract: A shoe lace holder (LH) to assist in the tying of shoe laces (L) and to prevent shoe laces inadvertently coming undone during use is disclosed. The shoelace holder includes a unitary body having top and bottom surfaces defined by a front edge, a back edge and side edges. The body includes at least one first hole (7) and at least one second hole (8), two slots (3, 4), which extend in opposite directions relative to each other, and at least two further holes (11, 12) spaced apart from each other. The holes allow a shoe lace to pass through, and the slots are adapted to engage a portion of the shoe lace there in. When attached to a shoe a shoe's laces are interwoven through the respective holes and slots to prevent the lace inadvertently untying in use. A method of securing a shoe lace to the shoe lace holder is also disclosed.

Abstract: An apparatus configured to control fluid distribution between at least one fluid circulation system (2) associated with equipment (3) and at least two replaceable fluid containers (4), the apparatus having: a fluid path (5) configured to couple to at least one fluid port (6) of the fluid circulation system (2), and to at least one fluid port (7) of each of the replaceable fluid containers (4), the fluid path (5) having at least one valve (8) between the fluid circulation system (2) and at least one replaceable fluid container (4); and a control apparatus (9) configured to control the at least one valve (8) to control the flow of fluid between the fluid circulation system (2) and the at least two replaceable fluid containers (4).

Abstract: A fully mechanized method for making artificial knotted pet chews such as edible dog bones. The method employs a knot box having a tubular chamber in the form of a knot. Rolled or folded pet chew material is mechanically inserted into and pushed through the chamber of the knot box, clamped at the far end, pulled from both ends to form a knot, and then withdrawn. According to one embodiment, the knot box separates to facilitate knotting and withdrawal of the knotted chew. The process is repeated for double knotted chew. The method can be used with pet chews made from treated rawhide, extruded plant material, and rawhide or extruded plant material combined with a meat layer. The method allows the manufacture of knotted dog bones without the use of human labor, avoiding the consequent costs and other drawbacks encountered when requiring workers to engage in simple, repetitive manual tasks.

Abstract: The present invention relates to a sensing system which is capable of discriminating types of causes of changing loads on a surface, such as the type of motion of a human subject. The system has wide ranging applications including sports performance (e.g. golf club swing analysis). The system comprises a deformable load bearing surface (2), a plurality of mutually spaced sensors (6), a processor (8) and an output (10). The sensors (6) are coupled through the deformation response of the surface (2) to an applied load (4) to receive local sensory data from the surface (2). The processor (8) is operatively coupled to the sensors (6) and is arranged to transform the sensory data into information data relating to a load (4) applied to the surface (2), e.g. by means of a neural network algorithm. In an alternative embodiment, a housing including the deformable load bearing surface (2) contains a flowable material (e.g. liquid) which flows in response to the deformation of the surface.
