摘要： A remanufactured pinion shaft includes a salvage member secured to a replacement member. The salvage member may be formed from a damaged pinion shaft and includes first gear teeth proximate a first axial end and a first alignment member proximate a second axial end. The replacement member includes second gear teeth proximate a first axial end and a second alignment member proximate a second axial end. The first alignment member and the second alignment member cooperate to transmit rotational motion between the first salvage member and the replacement member and/or align the salvage member relative to the replacement member.

摘要： A machine control system can store model weights determined via machine learning using a training dataset correlating preset hydraulic valve displacements to measured movement parameters of a machine component. The machine control system can receive an input command for the component and machine state data from machine sensors. A control mapping model can use the model weights to map a combination of the input command and the machine state data into a predicted displacement of the hydraulic valve that causes movement of the component in response to the input command.

摘要： A wrench for tightening and loosening lug nuts may include a head disposed on a distal end of a handle. The head defines a curved inner surface facing an axis and an opening configured to receive a portion of a lug. One or more supports are formed on the curved inner surface, extending toward the axis. The supports are spaced from the opening and are configured to contact an outer surface of the lug with the portion of the lug received in the opening.

摘要： A method includes storing a plurality of content items and storing one or more associations. Each of the associations includes an association between exactly two of the content items. The method may also include causing a graphical user interface (GUI) to be presented on an electronic device. The GUI may include a first representation of a first content item, a list of representations comprising a second representation of a second content item and a third representation of a third content item, a first visual indicator indicating a first association between the first content item and the second content item, and a second visual indicator indicating a second association between the first content item and the third content item. The method may also include receiving a user input comprising an instruction to create an additional association between the first content item and the second content item.

摘要： A tipping avoidance system configured to modify operation of a collision avoidance system. The tipping avoidance system may include a payload determination system configured to generate a payload signal, and a load position determination system configured to generate a load position signal. The tipping avoidance system may also include a tipping avoidance controller configured to receive the payload signal and the load position signal, and determine, based at least in part on the payload signal and the load position signal, a minimum stopping distance at or above which the machine will not tip due at least in part to deceleration of the machine from a travel speed to a stopped condition. The tipping avoidance controller may be configured to communicate with a braking controller, such that the braking controller adjusts a stop triggering distance based at least in part on the minimum stopping distance.

摘要： A method for determining part wear, such as using a wear metric, includes receiving, from a sensor, sensor data representing a surface of a wear part. The method further includes determining distances between measured points in the sensor data and points on one or more part models, which part models may include new part models and/or worn or wear limit part models. The method further includes using a bounding model that at least partially envelopes the part model(s) and the measured points to determine a direction along which the distances are measured. The method may also include quantifying wear using the measured distances.

摘要： A radiator guard may include a front plate, a top plate, spaced side plates, gussets and yoke assemblies. The front plate may have a varied profile such that a first lateral width proximate a top of the front plate is greater than a second lateral width proximate a bottom of the front plate. The top plate may be angled relative to the front plate and the side plates may be fixed near the lateral sides of the front plate such that portions of the front plate proximate the top of the front plate extend laterally outwardly from the side plates. The gussets may be disposed on the rear surface of the face plate at these laterally extending portions and the yoke assemblies may be disposed on the front surface of these portions.

摘要： An apparatus includes a coverlay layer having a void therein. A backing layer is disposed against a first side of the coverlay layer. A transmission layer is disposed against a second side of the coverlay layer opposite the first side such that a chamber is formed within the void between the transmission layer and the backing layer. The transmission layer includes a first area having a first level of light transmissivity and a second area having a second level of light transmissivity that is greater than the first level of light transmissivity. The transmission layer is oriented so that at least a portion of each of the first area and the second area overlaps the void. A light source is positioned in the chamber between the first area of the transmission layer and the backing layer.

摘要： A measuring system for performing measurements on a device under test is provided. The measuring system comprises a measuring device, a probe connected to the measuring device, a power sensor and a positioning unit. The positioning unit is adapted to connect the probe to the power sensor in a first configuration and to the device under test in a second configuration. The measuring device is adapted to generate a first signal. The probe is adapted to supply the first signal to the power sensor and the first configuration and to supply the first signal to the device under test and the second configuration. The power sensor is adapted to determine the power of the first signal and the first configuration. The measuring device is adapted to regulate the power of the first signal in the second configuration based upon the power determined by the power sensor.
