Abstract: A roadway grinding system is disclosed and can include a frame and a first cutting blade disposed within the frame. The first cutting blade can include a core. Further, a plurality of abrasive segments can be spaced apart from each other on the core. A first sensor can be disposed on the frame and can be configured to detect blade wear as a change in the distance between an outermost circumference of the first cutting blade and a predetermined distance.

Abstract: Systems and methods for improved operation of hand tools are disclosed. Sensors may be configured to monitor one or more operational parameters of a hand tool and collected data may be communicated to the hand tool operator. The data may be compared to predetermined limits for an operational parameter to enable real-time operational diagnostics and quantitative control. Data can be collected across a manufacturing facility and analyzed to help account for variations in technique and skill among operators. An understanding of relationships between monitored operational parameters can lead to improved consistency among finished products and reduction in manufacturing costs. Data may also be stored for future recall and analysis.

Abstract: An apparatus and method is provided for monitoring operation of a roadway grinding/cutting machine of the type configured to travel along a roadway while engaging and grinding the roadway with a grinding/cutting head. A first displacement sensor generates, during the travel, first distance data associated with a distance between a reference level and a location on the roadway ahead of the grinding zone. A second displacement sensor generates, during the travel, second distance data associated with a distance between the reference level and a location on the roadway behind the grinding zone. A processor captures and uses the first and second distance data to determine a depth of cut as grinding/cutting progresses.
