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: A system, device and processes that can provide a user with a way to prevent the loss or misplacement of their eyeglass frames (or other item) in the situation in which the eyeglasses (or other item) has been taken off and placed on a table, or otherwise left behind, etc. Embodiments of the invention incorporate a wireless communications technology, such as a Bluetooth module or similar functional module that is embedded into the eyeglass frame during manufacture and is therefore an integral part of the frame. In the case of an item other than eyeglass frames, the Bluetooth module may be embedded into a clasp, link, setting, or a part of a device (such as a laptop computer).

Abstract: A system, device and processes that can provide a user with a way to prevent the loss or misplacement of an item of value. In some embodiments, a wireless communications technology, such as a Bluetooth module (e.g., Bluetooth Low Energy, BLE) or similar functional module is embedded in, or otherwise incorporated into the item of value. For example, an embodiment may utilize the Bluetooth communications capability of a smartphone, laptop, or tablet computer. In this embodiment, an alert component in the possession of a user communicates with the Bluetooth module associated with the item of value.
