Abstract: A shopping cart includes a wheeled base and a basket. The basket is supported above a wheeled base and includes a hook. The basket defines a compartment, a top mouth open to the compartment, and an open slot positioned below the top mouth. The open slot is defined between a top edge and a bottom edge thereof, and the bottom edge is positioned opposite the top edge. The hook downwardly depends from the top edge of the open slot toward the bottom edge of the open slot to a free bottom end of the hook. The hook is configured to selectively receive a handle of a bag after the handle of the bag is wrapped around a portion of the basket defined between the open slot and the top mouth of the compartment, such that the bag selectively hangs along an outside surface of the basket opposite the compartment.

Abstract: A machine, such as a hauler at a mining site, includes one or more bolted (clamped) joints. Friction coatings are applied to surfaces of two or more materials being clamped to reduce clamp load loss. The friction coatings include one or more coated surfaces and one or more interstitial spaces between the coated surfaces. Various materials may be used as the friction coating including, but not limited to, a tungsten/carbide or stellite/carbide alloy, iron base alloys such as POLYMET alloys, including PMET 290 (an alloy of iron, chromium, boron, manganese, silicone, and nickel), a nickel chromium alloy, e.g., Ni-20Cr, aluminum oxide (Al2O3) particles, and various combinations of these and other suitable materials.

Abstract: An example bushing has three portions along its radial direction including an inner portion most proximal to a central hole of the bushing, an outer portion most distal from the center hole, and a core portion between the inner portion and the outer portion. The core portion has a hardness that is less than the hardness of the inner portion or the outer portion of the bushing. The bushing may be formed using high carbon steel, which in some cases may be spheroidal cementite crystal structure. A rough bushing may be formed using the high carbon steel, followed by a direct hardening process, and an induction hardening process on the inner surface most proximal to the central hole of the bushing. The induction hardening on the inner surface may harden the outer portion while tempering the core portion of the bushing.

Abstract: An example track shoe, cutting edge, or other component of a machine is formed in a heated process, such as hot-rolling followed by air-hardening. The air-hardening process involves cooling the component by flowing air over the component (e.g., air cooling), such that the component is cooled at a controlled rate. During the air-cooling process, such as in the range of about 250° C. to about 1100° C., the component may be machined, such as by shearing, punching, drilling, etc. The machining may form the final shape of the component. As the air-hardening process is completed, and the component approaches room temperature, the component may have at least 5% bainitic crystal composition, and as high as greater than 80% bainitic crystal composition, resulting in relatively high hardness and fracture toughness. The final track shoe may have a hardness between about 40 HRC and 55 HRC.

Abstract: A three-dimensional model (e.g., motion capture model) of a user is generated from captured images or captured video of the user. A machine learning network may track poses and expressions of the user to generate and refine the three-dimensional model. Refinement of the three-dimensional model may provide more accurate tracking of the user's face. Refining of the three-dimensional model may include refining the determinations of poses and expressions at defined locations (e.g., eye corners and/or nose) in the three-dimensional model. The refining may occur in an iterative process. Tracking of the three-dimensional model over time (e.g., during video capture) may be used to generate an animated three-dimensional model (e.g., an animated puppet) of the user that simulates the user's poses and expressions.

Abstract: A lighting system comprises a plurality of lights, a sensor for measuring a light level associated with each light, and at least one controller for generating a light output from at least one light of the plurality of lights. The controller is adapted for adjusting the light output from the at least one light by an incremental amount to bring the measured light level closer to a target light level, which may correspond to an overall brightness for the space including the lights.
