Abstract: A device and methods for raising an underground footing or foundation beneath a structure such as a home, office building or roadway, using a means of pumping expandable fluid into substratum below the area to be raised. The device includes an elongated shaft comprising a trailing end and a leading end and may define a fluid pathway from the upstream trailing end to the downstream leading end. The trailing end is adapted to secure fluid communication between the fluid pathway and the means of pumping expandable fluid may include. The fluid pathway terminates in a downstream fluid pathway exit, in a section of the leading end having a reduced diameter smaller than a diameter of the leading end upstream from said fluid pathway exit. The leading end further comprises a tip region converging to a point facilitating pushing of the leading end deeper into the substratum.

Abstract: Systems and methods of passive intermodulation (PIM) detection in a radio frequency (RF) system including: injecting, from each port of a two-port PIM analyzer, two test tones or a wideband modulated carrier signal into the system one port at a time; receiving, at each port, a response signal from the system in response to the test tones or wideband modulated carrier signal; injecting, from two ports of the two-port PIM analyzer, test tones or a wideband modulated carrier signal into the system; receiving, at the two ports, a response signal from the system in response to the test tones or wideband modulated carrier signal; and identifying one or more PIM sources based on the response signals.

Abstract: In one or more implementations, body features of a subject can be tracked and a pose estimation produced using an unconstrained video sequence. The video sequence constitutes a physical record of the body features of the subject. A set of 2D coordinates corresponding to the body features of the subject can be received from a first neural network and 2D Keypoints are detected and transmitted to a second neural network. The second neural network can return corresponding depth estimation values, which can be processed to generate a set of 3D coordinates that correspond to the body features of the subject in camera space. Furthermore, one or more non-linear optimizations can be applied to fit a predetermined skeleton to the generate 3D Keypoints, and produce the pose estimation corresponding to the body features of the subject.

Abstract: A fender for a lawn mower having tire and wheel assemblies that are mounted to a yoke of a swivel caster assembly, whereby the yoke pivots through 360 degrees of rotation, includes an arcuate fender body. The fender body is attached to the yoke by a bracket so that it is rotatably carried by the rotating yoke. As such, the fender body is maintained at an optimal position relative to the mower tire and thereby provides desirable deflection of lawn clippings and other debris from the various operational components provided upon the mower deck. This prevents the premature wear of such operational components, thereby decreasing down time and reducing maintenance costs of the mower.

Abstract: An evaporative emission control system for a vehicle includes an engine, a fuel tank connected to the engine and a reversible purge pump connected between the fuel tank and the engine. Fuel vapor generated in the fuel tank is supplied to the engine. The purge pump is operable in a first direction to supply the fuel vapor from the fuel tank to the engine and a second direction to supply air to the fuel tank. A purge control valve is connected between the reversible purge pump and the engine to control a flow of the fuel vapor to the engine.

Abstract: The present disclosure relates to a fluid seal to prevent fluid and lubricant loss during automotive transmission testing. The fluid seal may be disposed on a surface of an axle shaft such that a variety of transmissions may be evaluated without replacement of the axle shaft, a laborious and ergonomically stressful task. Moreover, the fluid seal may be disposed on a standard collar of the axle shaft for interaction with an internal surface of a transmission coupler.

Abstract: A method for locating and tracking facial features in an unconstrained video sequence includes: in a face-detecting process, delineating, with region-bounding coordinates, the face of the subject within an image selected from the sequence; detecting, in the selected image, a small set of landmarks, corresponding to the face of the subject, using a convolutional neural network, trained to take as input an image region corresponding to the face of the—subject and to return a set of coordinates at computational speeds approximating real time; projectively fitting a three-dimensional character model to the detected landmarks, and using the fitted model to estimate physical locations of additional landmarks, so as to provide a complete hypothesized set of facial landmarks; and in a feature tracker process, updating the hypothesized set of facial landmarks to improve convergence between predicted feature locations and their actual physical locations based on data sampled from the selected image.

Abstract: Users are most likely to search for documents “around” them, such as documents which are created, read, or modified by other users they work closely or collaborate with, documents on sites the user frequents, and/or documents trending around them, in addition to documents they've created or interacted with themselves. Therefore, embodiments are directed to relevance ranking of query results based on external context. A search service may receive a query and an external context list, determine a relevance value for each entry in the external context list, and perform the query, where a search index comprising items may be returned in response to performance of the query. The search service may then match entries in the external context list against associated properties of the items, compute a score for the items based on the matching, and rank results of the query based on the score computed for the items.
