Abstract: A tool interchange for a submersible remote operated vehicle (ROV) arm includes a first interchange body that affixes to an ROV arm. A second interchange body is carried by the first interchange body to rotate on a rotation axis. The second interchange body includes a tool mount actuable between gripping an ROV tool to the second interchange body and releasing the ROV tool from the second interchange body. An inductive power coupling part is provided in the tool mount. The inductive power coupling part is presented outwardly in the tool mount opposite the first interchange body, resides on the rotation axis and is fixed with respect to the first interchange body while the second interchange body rotates. The inductive power coupling part is adapted to inductively communicate power with a corresponding inductor power coupling part of the ROV tool when the ROV tool is docked in the tool mount.

A battery may be communicatively coupleable with the pressure washer controller for one or more of receiving data from the pressure washer controller and transmitting data to the pressure washer controller. The battery may include a memory module for storing one or more of data received from the pressure washer controller and data to be transmitted to the pressure washer controller.

Abstract: Disclosed is a disposable for use with a structure having a vessel surface that defines a vessel for receiving liquid. The disposable includes a pad and a layer. The pad has a pair of surfaces spaced apart from one another by a tubular sidewall. The pad is permeable to air flow. One of the pair of surfaces is positioned, in use, against the vessel surface. The layer overlies the other of the pair of surfaces and is at least substantially impermeable to air flow. In use, gas is introduced into the pad and issues through the sidewall in the form of bubbles. The disposable is useful in association with foot spas and the like.

Abstract: An illuminated foot spa is provided. The foot spa has a surface which defines a basin for containing water and a pump magnetically driven by rotating magnets. A mount defines part of the surface and holds the pump against rotation. A coil associated with the mount and disposed exteriorly of the surface of the basin and interiorly of a magnetic field produced by the rotating magnets to produce a current in the coil that powers a plurality of lights operatively connected to the coil. The light conductivity associated with the mount permits the plurality of lights to be visible interiorly of the basin.

Abstract: A kit of parts for use in unicondylar meniscal bearing knee replacement comprises a plurality of meniscal bearings, each meniscal bearing comprising a body defining a dished first bearing surface on one side thereof and a second surface on an opposing side of the body. Each meniscal bearing has an entrapment between 3.2 mm and 3.8 mm. Meniscal bearings and methods of performing unicondylar meniscal bearing replacements are also described.

Abstract: An improved authentication, identification, and/or verification system is provided in various embodiments.
