Abstract: The utility usage of a particular individual occupying a residence may give insight into the individual's current cognitive health and/or to enable provision of various services within the facility for the individual, particularly when monitoring patterns in utility usage over time. To enable accurate and non-invasive utility monitoring, a single-point utility sensor may be secured relative to a utility supply line, and generated signals may be utilized to monitor utility usage and to distinguish between utility fixtures. A centralized computing entity may identify frequency characteristics within the generated data, and may automatically generate one or more machine-learning algorithms to distinguish between utility usage events, without requiring substantial user input.

Abstract: A fluid end assembly of a hydraulic fluid pump includes a housing having a bore, a removable valve cover closing the bore, and a retainer engaging the bore. The retainer includes a set screw bore that extends from a first side of the retainer to a second side of the retainer, opposite the first side. The fluid end assembly further includes a set screw. The set screw is threaded into the set screw bore from the first side of the retainer. The set screw is not removable from the second side of the retainer. The first side of the retainer is positioned adjacent to the valve cover.

Abstract: A fluid end assembly of a hydraulic fluid pump includes a housing having an axial bore, a removable valve cover closing the axial bore, and a retainer engaging the axial bore. The retainer includes a central opening. The fluid end assembly further includes a threaded drive member positioned within the central opening and operable to apply a preload against the retainer.

Abstract: A method of determining the location of a candidate object in an environment, the method including the steps of: (a) capturing a 3D point cloud scan of the object and its surrounds; (b) forming a surface geometry model of the candidate object. (c) forming a range hypothesis test comparing an expected range from the geometry model of the candidate object in comparison with the measured range of points in the Lidar point cloud scan and deriving an error measure there between; (d) testing the range hypothesis for a series of expected locations for the surface geometry model of the candidate object and determining a likely lowest error measure.

Abstract: A capillary block can be provided in any of a number of different geometries for soldering and brazing. The capillary block can be configured to be positioned adjacent a joint to be formed prior to heating. Heat can then be applied to melt the capillary block and cause it to wick into the interface between the members being joined. The capillary block can be used in place of or in addition to a frame preform to create a joint such as a wall-to-floor joint of an assembly.
