A replacement part validation system is presented that includes a scanning system that scans a received part and provides the scan results of the received part. The system also includes a part recognition module that, based on the received scan results of the received part and provides a part identification and a part quality metric. The system also includes a job assignment module that assigns the received part to an outstanding repair job. The system also includes an output generator that outputs the outstanding repair job and the part quality metric. The system also includes a computing processor that, based on the received scanned results, causes the part recognition module to review a database of parts and retrieve a most-likely match. The part quality metric is based on a comparison of the received part to the most-likely match. The computing processor causes the output generator to output the outstanding repair job and part quality metric to a source.

Replacement part validation systems and methods

A robotic paint repair system that can comprise: a consumable abrasive product configured to abrade a substrate, a tool configured to drive the consumable abrasive product to abrade, a robotic device configured to manipulate the tool and a compliant accessory actuator positioned between the tool and the substrate, wherein the compliant accessory actuator is driven to apply a desired force and a desired stiffness to the consumable abrasive product in response to sensed data collected between the tool and the substrate.

Robotic paint repair systems and methods

Methods and apparatus including a fiber opening chamber having an open upper end and a lower end, at least one fiber inlet for introducing a multiplicity of fibers into the opening chamber, a first multiplicity of rollers positioned within the opening chamber wherein each roller has a multiplicity of projections extending outwardly from a circumferential surface surrounding a center axis of rotation, at least one gas emission nozzle positioned substantially below the first multiplicity of rollers to direct a gas stream generally towards the open upper end of the opening chamber, and a forming chamber having an upper end and a lower end, wherein the upper end of the forming chamber is in flow communication with the open upper end of the opening chamber, and the lower end of the forming chamber is substantially open and positioned above a collector having a collector surface.

Apparatus and methods for producing nonwoven fibrous webs

Methods and apparatus including a chamber having a substantially open lower end positioned above a collector surface, at least one fiber inlet positioned above the lower end, a first multiplicity of rollers positioned within the chamber wherein each roller has a multiplicity of projections extending outwardly from a circumferential surface surrounding a center axis of rotation, a second multiplicity of rollers positioned within the chamber above the first multiplicity of rollers wherein each of the second multiplicity of rollers has a multiplicity of projections extending outwardly from a circumferential surface surrounding a center axis of rotation, the second multiplicity of rollers positioned so at least a portion of the projections extending outwardly from the circumferential surfaces of each of the second multiplicity of rollers vertically overlaps with at least a portion of the projections extending outwardly from the circumferential surface of at least one of the first multiplicity of rollers.

Methods and apparatus for producing nonwoven fibrous webs

A continuous concrete curb forming apparatus is formed by a vertical open end sleeve-like hopper having a channel-like member connected with its depending opening forming the shape of a conventional concrete curb as wet concrete poured in the hopper is released from the channel member. The hopper is connected with one end of a rectangular frame mounted on the forward end of a tractor. Hydraulically operated cylinders on the apparatus are connected with the tractor hydraulic system and a sensing means responsive to the position of a horizontal guide strand defining the position of the concrete curb to be extruded are connected with the hydraulic system through servo-mechanisms for guiding the tractor and maintaining the hopper and extruding channel in close spaced relation with the surface of a roadbed on which the concrete curb is to be extruded.
