Abstract: A collapsible equipment tower is operable between an extended configuration and a contracted configuration. The equipment tower has a base, having a base frame and supporting a solar panel, and a pivot support, having a distal end for supporting equipment and a proximal end. The pivot support is pivotally connected to the base frame at a pivot joint at the proximal end and is pivotable between a substantially upright position in the extended configuration and a transverse position in the contracted configuration. A retractable locking member is provided at the proximal end of the pivot support adjacent to the pivot joint. The locking member is adapted to be extended from the proximal end and secured to the base frame in the extended configuration and to be retracted in the contracted configuration.

Abstract: The abrasive pad is removably affixed to the first end and configured to be easily adjustable by release of a hook and loop connection arrangement affixing the abrasive pad to the plate. The grip end and the abrasive pad end of the plate are separated by a specific angle medial bend which facilitate use of the tool in an ergonomic manner. The tool includes a rectangular plate having a first end wrapped with an adjustable abrasive pad and a second grip end. The plate is in the form of a rectangular, parallelepiped with a medial bend between the first end and second end.

Abstract: Disclosed are systems and methods for measuring the fluid quality of oil, or other fluids used in or with equipment, machinery and the like. The system may be integrated with a filter device and used, for example, to characterize such fluids and to permit a determination of when to make oil or other fluid changes due to a change in the quality of the oil or fluid.
