Abstract: In some embodiments, techniques are provided for improving the detection of repeated actions during the manipulation of tabular data in order to enable the creation of automated action sequences. Activity log records are created that represent actions taken with respect to a set of tabular data. One or more normalized versions of the activity log records may be created. The activity log records (and, in some embodiments, the normalized versions of the activity log records) may be grouped and hashed together, such that groups of activity log records may be compared to each other by comparing the resulting hashes. Grouping and hashing may allow large numbers of comparisons to be made efficiently enough to support detection of repeated actions on large scale, multi-user, and multi-tenant systems.

Abstract: A tread pattern for a vehicle track, such as an endless track for earth moving equipment, comprises a plurality of blocks. Each block includes two lateral traction portions extending from a center traction portion in substantially opposite directions. The two lateral traction portions are longitudinally aligned. In some examples, each lateral traction portion may define a T-shape. For example, the lateral traction portions of each block may define a protrusion to define the “T” shape, and, in some examples, the protrusions may extend in opposite longitudinal directions. In some examples, the lateral traction portions of each block may be the same shape, where one lateral traction portion may be oriented at about 180 degrees relative to the other lateral traction portion.

Abstract: A sensor sleeve for use in detecting a failure in an article (e.g., a hydraulic hose), the sensor sleeve includes an insulator layer that separates two electrode layers. As such, the electrode layers deform to contact each other, which changes the impedance as measured across the electrode layers. The sensor sleeve is designed to change electrical impedance (resistance) due to fluid pressure initiating a hole through the sensor itself. The sensor sleeve will detect the fluid leak when the hole penetrates the sensor and brings the two elastic electrodes in contact with each other and/or the fluid, which when the fluid is conductive fluid, creates a signal path between the first electrode layer and the second electrode layer, which also changes the impedance as measured across the electrode layers.
