Abstract: Surgical systems and methods of operating the same involve controlling a robotic manipulator to move a cutting instrument to cut away material from a bone at a surgical site. A machine vision system uses a vision camera to detect an object at, or in proximity to, the surgical site. A control system associates a virtual boundary with the detected object and controls the robotic manipulator to move the cutting instrument based on the virtual boundary such that the cutting instrument avoids the detected object. In one example, the control system modifies a tool path of the cutting instrument based on the virtual boundary to avoid the detected object. Additionally, or alternatively, the control system can automatically adjust an orientation of the cutting instrument based on the virtual boundary to avoid the detected object.

Abstract: A surgical system, method, and non-transitory computer readable medium involving a robotic manipulator configured to move a surgical instrument relative to virtual boundaries. A navigation system tracks each of a first object, a second object, and the surgical instrument. The first object is moveable relative to the second object. One or more controllers associate a first virtual boundary with the first object and associate a second virtual boundary with the second object. The first virtual boundary is moveable in relation to the second virtual boundary. The controller(s) control the robotic manipulator in relation to the first virtual boundary to facilitate interaction of the surgical instrument with the first object. The controller(s) control the robotic manipulator in relation to the second virtual boundary to avoid interaction of the surgical instrument with the second object.

Abstract: An improved cleaning basin (including cover and stand) for commercial grill, oven and stove ventilation filters. The device allows convenient soaking and cleaning of the filters in cleaning solution, and provides for safe and efficient drainage of the solution. The device is specially sized to facilitate simultaneous cleaning and soaking of multiple filters in caustic cleaning solution, and it provides for safe and efficient filling and drainage of the solution from the basin. The device is rugged, durable, weather-proof, and it can be manufactured at nominal cost.

Abstract: An improved extended mounting bracket for a french fry press. The mounting bracket generally comprises a back plate with two opposing protruding side brackets. The side brackets are integrally attached along the opposing edges of the back plate by welding or the like. Both side brackets are formed with upper and lower notches adapted to slidably receive and anchor a conventional french fry press. The extended mounting bracket extends the french fry press over a proper waste receptacle such as a sink and thereby facilitates efficient waste disposal and cleanup. The bracket is rugged, durable, and it can be manufactured at nominal cost.

Abstract: The invention is directed to a medical transport device for moving a patient down a flight of stairs. A chair has a plurality of support members. A plurality of rollers are each connected to at least one of the support members. At least one tread defining a bottom surface is wrapped around the rollers. A slider is disposed adjacent to the plurality of rollers. The slider has a bottom edge which is disposed slightly above the bottom surface of the tread.
