Abstract: A method for reconditioning a compactor wheel of a compaction machine is provided. The method includes mounting a compactor wheel on a positioning system configured to provide one or more of angular adjustment, vertical and horizontal translation, and rotation of the compactor wheel, so as to position the compactor wheel in a desired position. The method also includes providing a welding system configured to perform a submerged arc strip welding or weld cladding operation on the compactor wheel. The submerged arc strip welding or weld cladding operation is performed on at least one surface or edge of the compactor wheel to add weldable material thereto, so as to recondition the at least one surface or edge of the compactor wheel.

Abstract: An inspection apparatus including a light source, a sample holding stage, an image capture device, positioned to receive light from the light source after the light has interacted with a sample on the sample holding stage, and a damage metric. The damage metric includes two or more damage levels, and is a function of light in a test image. Further, the damage metric may correlate to visual observation so that an inspection apparatus may mimic how users of devices will perceive damage to the devices. The damage metric may be adjusted to account for different damage types, for example, abrasion and scratch damage.

Abstract: The disclosed computer-implemented method for sending push notifications that include preferred data center routing information may include (1) configuring at least one rule for determining which data center out of a plurality of data centers is preferred to serve one or more download requests, (2) identifying a push notification that is configured to prompt a device to download data from a data center within the plurality of data centers, (3) using the rule to select, from the plurality of data centers, a preferred data center to which to route the device, and (4) embedding information about the preferred data center in the push notification sent to the device. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A method for self-notification avoidance in a push notification system is provided. The method includes receiving, at a server configured to provide a push notification service, a notification from one of a plurality of endpoint devices to be pushed to the plurality of endpoint devices, wherein the plurality of endpoint devices has a shared identifier, and wherein the one of the plurality of endpoint devices has a globally unique identifier (GUID). The method includes identifying, at the server, the globally unique identifier in the notification and pushing the notification from the server to each of the plurality of endpoint devices having the shared identifier except the one of the plurality of endpoint devices that has the globally unique identifier.

Abstract: A strengthened glass article having a central tension that is below a threshold value above which the glass exhibits frangible behavior. The central tension varies non-linearly with the thickness of the glass. The glass article may be used as cover plates or windows for portable or mobile electronic devices such as cellular phones, music players, information terminal (IT) devices, including laptop computers, and the like.

Abstract: A compactor wheel for reducing the amount of material build-up, providing sufficient tractive forces, and effectively holding loose debris to prevent fly-away is disclosed. The compactor wheel includes a hub mountable to an axle of a compaction machine and a rim mounted around an outer circumference of the hub, with the rim including a wrapper having an inner circumferential edge and an outer circumferential edge. The compactor wheel also includes a plurality of cleat pads formed on the wrapper that each extend axially outward from the wrapper, with the plurality of cleat pads being spaced apart from one another on the wrapper such that a valley is formed between each adjacent pair of cleat pads. A plurality of cleats is affixed to each of the plurality of cleat pads and extends radially outward therefrom.

Abstract: A compactor cleat includes a bottom face affixable to a compactor wheel and having a perimeter defining an outline of the compactor cleat, a cutting face distal from the bottom face and radially outward from the compactor wheel, a pair of side faces extending between the bottom face and the cutting face, and a pair of traction faces positioned between the pair of side surfaces on opposing sides of the compactor cleat and extending between the bottom face and the cutting face. Each traction face comprises a bi-facial traction face that includes a first section including a sloped surface extending downwardly and outwardly from the cutting face towards the bottom face for less than a full height of the compactor cleat, and a second section formed adjacent the first section that has a concave surface that forms a transition between the second section and the perimeter of the bottom face.

Abstract: A two-piece construction compaction cleat and method of manufacturing thereof is disclosed. The compactor includes a base member affixable to a compactor wheel and having a bottom portion and a center flange, with the center flange extending upwardly from the bottom portion to form an upper ridge and being generally aligned along a center line of the base member. The compactor cleat also includes a cap member secured to the base member and positioned thereover so as to cover at least a portion of the base member, with the cap member having an arrangement of openings configured to receive the center flange therein. The center flange of the base member and the arrangement of openings formed in the cap member are configured to provide for a size-on-size fit between the base member and the cap member, so as to secure the cap member to the base member.
