Abstract: Methods and systems for managing workplace task compliance is disclosed. The method includes, receiving, by a computing device, a request from an operator, wherein the request includes a particular workplace task, providing a camera unit and a display device in an environment in which the particular workplace task is to be completed, capturing, by the camera unit, one or more images of the environment, utilizing a machine learning model configured to provide a safety compliance status of the environment, inputting a plurality of values from the captured images of the environment into the machine learning model, outputting values from the machine learning model to determine the safety compliance status of the environment, and alerting the operator of the determined safety compliance status of the environment.

Abstract: A valve for regulating the flow of ferromagnetic peening materials, consisting of an arrangement of pole pieces, spacers, permanent magnets, and electrical coils. This arrangement uses an angular magnetic field to concentrate holding strength within the working gaps without sacrificing holding strength to the environment, increasing the valve's efficiency. Additionally, this valve covers a large range of flow rates by exchanging center bars and magnets of different sizes, without otherwise increasing the size of the valve.

Abstract: A sacrificial media shield to be used in flow control valves in high volume wheel blast peening machines, comprised from a wear resistant material. This shield is intended to prevent undesired wear to the valve and its components via an offset arrangement, which isolates the majority of contact with the abrasive media stream to the media shield. This prevents plastic contamination within the media stream. Being a replaceable component, the shield extends the operating life of the valve by avoiding replacement of the valve in its entirety.

Abstract: This application describes a magnetic valve for controlling the flow of media in wheel-blast style abrasive blasting cabinets. The valve features a novel air aspiration system comprising of aspiration inlets, chamber, and outlets, in a configuration which guarantees passage of air from ambient into the peening system regardless of installation. This system acts as a passive aspiration source to counteract the negative pressures imposed by the wheel-blast blades in the valve's off-state. This arrangement eliminates the need for other means of aspiration to be installed in the peening system by the end user.

Abstract: Described are techniques for determining population structure from identity-by-descent (IBD) of individuals. The techniques may be used to predict that an individual belongs to zero, one or more of a number of communities identified within an IBD network. Additional data may be used to annotate the communities with birth location, surname, and ethnicity information. In turn, these data may be used to provide to an individual a prediction of membership to zero, one or more communities, accompanied by a summary of the information annotated to those communities. Ethnicity heterogeneity and age information may be tabulated and provided based on community membership information.

Abstract: A water treatment tank is constructed from several adjoining intermodal containers (ICs). The adjoining ICs are angularly disposed relative to each other so as to surround a tank area. Each IC has a reinforced sidewall defining a tank wall or tank wall part. A bracing structure is attached to ICs end walls at each junction between adjoining ICs. The tank having a liner supported at the sidewalls and covering the ground at the tank area.

Abstract: A sludge collector arrangement has a settling tank having side walls sloping downwardly and inwardly towards the base of the tank to from a V-base. A sludge collection unit located in the bottom of the tank has one funnel part facing in one direction and another funnel part facing in the other direction so that when the unit is driven backwards and forwards in the V-base, sludge is driven into one or other of the funnel parts. The funnel parts communicate with a central chamber and a port in a wall of the chamber allows sludge to be drawn by a suction pump from the chamber for subsequent disposal.

Abstract: Location information may be provided for a mobile station based on the serving area that is currently serving the mobile station. The location information may include a representative location (e.g., a centroid location of the serving area) and an uncertainty (e.g., a distance between the representative location and a boundary of the serving area). The representative location and uncertainty for a serving area may depend on the status of at least one neighboring area. For example, the effective size of a serving area may become larger when a neighboring area is heavily loaded or out of service. In an embodiment, a location server receives a request to locate a mobile station, selects a representative location and uncertainty for the serving area that is serving the mobile station based on the status of at least one neighboring area, and reports the representative location and uncertainty in response to the request.

Abstract: A set of location fixes is obtained for a plurality of mobile stations, wherein each mobile station is served by a serving area of a wireless network at a respective date and time of day. The set of location fixes is used to determine different geographic parameters that apply to the serving area for different time periods (e.g., different days of the week and/or times of day). A location server may receive a request to locate a mobile station that is being served by the serving area at a current date/time. The location server may select a representative location and at least one uncertainty parameter based on the geographic parameters that apply to the serving area for the time period corresponding to the current date/time, and report the representative location and at least one uncertainty parameter in response to the request.
