Abstract: A floor mat has a base formed of an elastomer. A fibrous layer insert has a peripheral margin protected by a peripheral wall and an inwardly extending overhang of the base. A flange of the base surrounds and downwardly extends from the peripheral wall and ends at a floor plane. Spaced-apart flange support ribs downwardly extend from a lower surface of the flange to the floor plane.

Abstract: An interactive electronic trampoline assembly is made up of a frame, legs, a trampoline mat, a plurality of bias members to secure the trampoline mat to the frame, and a sensor to sense movement of the trampoline mat. A handlebar may also be connected to the frame. A control module may be removably secured to the assembly adjacent the frame. The control module may have a speaker, a power source, a controller, lights and control buttons. The sensor may also be housed in the control module. Different lights and sounds are output based on an input to the controller, the game being played and input received by the sensor.

Abstract: Robotic system and methods for robotic arthroplasty are provided. The robotic system includes a machining system and a guidance system. The guidance station tracks movement of one or more of various objects in the operating room, such as a surgical tool, a tibia of a patient, a talus of the patient, or a component of an implant. The guidance system tracks these objects for purposes of displaying their relative positions and orientations to the surgeon and, in some cases, for purposes of controlling movement of the surgical tool of the machining system relative to virtual cutting boundaries or other virtual objects associated with the tibia and talus to facilitate preparation of bone to receive an ankle implant system.

Abstract: An adjustable length strut includes two joints, a threaded rod extending between the joints, and a tube adapted to receive the threaded rod. An actuation mechanism with gear teeth extending radially outward of the strut axis is rotatably fixed to the threaded rod. A protrusion may be coupled to an end of the threaded rod by a rotatable collar, with the protrusion extending through a slot in the tube to mark the length of the strut. A modular attachment member may be adapted to be couple to the first joint and include a worm gear adapted to engage gear teeth of the actuation mechanism. The modular attachment member may include a radiofrequency identity tag mechanism adapted to be read by a tag reader of a tool, the tool adapted to couple to the attachment member to rotate the worm gear to increase or decrease the effective length of the strut.

Abstract: The invention is a system that enables passive sonar identification of underwater items by making use of lift bags and/or flags, having distinctive sequences of bands of sonar-signal-reflecting materials, wherein the lift items are partially inflated so as to present a predictable orientation with respect to the floor of a body of water and its surface.

Abstract: A powered ride-on vehicle having a frame supported by a first drive wheel, a second drive wheel and at least one non-driven support wheel. The vehicle has a first motor connected to the first drive wheel, a second motor connected to the second drive wheel, a steering wheel, a plurality of movement selectors, a dance selector, and one or more controllers operably electrically connected to the motors, the plurality of movement selectors, and the dance selector. The controllers operate to manipulate the motors to cause movements of the vehicle for a set period of time upon depression of one of the plurality of movement selectors independent of an angular location of the steering wheel. The controllers further operate to manipulate the motors to cycle through at least four different dances based on subsequent depression of the dance selector.
