Abstract: A teleoperated surgical system is provided comprising: a first robotic surgical instrument; an image capture; a user display; a user input command device coupled to receive user input commands to control movement of the first robotic surgical instrument; and a movement controller coupled to scale a rate of movement of the first robotic surgical instrument, based at least in part upon a surgical skill level at using the first robotic surgical instrument of the user providing the received user input commands, from a rate of movement indicated by the user input commands received at the user input command device.

Abstract: Smoke is removed from a building interior by a system in which a controller is activated upon a signal from any of one or more smoke detectors connected thereto. A conduit, with an air-receiving end located in the building and an air-exhaust end located outside the building, has an associated air mover arranged to exhaust air from the building through the conduit. A first and second valve in the conduit are normally closed, preventing air flow. On a smoke detection signal from the controller, the first valve and second valve open, the air mover actuates and air/smoke is withdrawn from the building until a “reset” signal is received. On reset, the air mover shuts down and the first and second valves close. The air-receiving end is preferably directly connected through a forced-air HVAC system of the building to avail use of its ducts and air movers.

Abstract: A device capable of gauging angles in the full range from 0.degree. to 360.degree.. The angle gauge has a pair of pivotally connected gauging arms. Each gauging arm is formed by a generally radially outwardly extending leg connected at one end to the pivot axis and a radially offset straight edge leg extending generally laterally from the opposite end of the radial leg. A full 360.degree. angle scale is fixed relative to one of the gauging arms coaxially with the pivot axis and extends radially outwardly a distance less than the offset of the straight edge. A pointer is fixed relative to the other gauging arm as a reading indicator operably associated with the scale. The arms may be clamped in selected angular positions and also may be used to lay out several angles about a common vertex.One of the gauging arms has a pitch scale formed along it and the other arm has an indicator mark formed on it.
