Abstract: A roller assembly for a mobile cleaning system for cleaning a work surface can include a drive shaft, a sheath, a bushing, and a bushing shroud. The drive shaft can be rotatable about a drive axis, and the drive shaft can include a driven end and an opposite bushing end. The sheath can be supported by the drive shaft and the sheath can be rotatable with the drive shaft. The sheath can include a shell engageable with the work surface. The bushing can be located about the bushing end of the drive shaft. The bushing shroud can be connected to the bushing. The sheath and the drive shaft can be together rotatable with respect to the bushing and the bushing shroud, the bushing shroud can include an outer portion defining a first radius of curvature and a recessed portion connected to the outer portion.

Abstract: An example method includes receiving, at a module management unit (MMU) associated with a battery cell, a battery cell parameter measurement associated with the battery cell. The MMU in is communication with a battery radio frequency module via a first link. The method further includes performing, by the MMU, a first function based at least in part on the battery cell parameter measurement to generate a first signal, and transmitting, from the MMU, the first signal to the battery radio frequency module via the first link. The method further includes performing, by the battery radio frequency module, a second function based at least in part on the first signal to generate a second signal. The method further includes transmitting, from the battery radio frequency module, the second signal to a controller, and performing, by the controller, a third function based at least in part on the second signal.

Abstract: An apparatus of a footwear securing device, is disclosed. The apparatus includes a shoelace, wherein the shoelace is configured to lace through one or more loop holes positioned on the footwear. The apparatus includes at least two retention devices positioned on a proximal end of the shoelace. The apparatus includes at least two retention devices positioned on a distal end of the shoelace. The at least one of the at least two retention devices on the proximal end of the shoe lace are configured to be removably attached from at least one of the at least two retention devices on the distal end.

Abstract: Methods and apparatus for identifying and analyzing clusters of medical billing claims in a queue to identify a shared root cause issue for the medical billing claims in the cluster. Exemplary methods and apparatus involve grouping each of the plurality of medical billing claims into clusters based on predetermined cluster patterns that include at least one attribute, validating the clusters using predetermined criteria to determine if the clusters should be analyzed, discarded, and/or marked for further analysis, collecting information about each of the medical billing claims in clusters, and determining a root cause issue for the medical billing claims in the clusters based on the collected information.
