    Abstract: A surgical robotic system comprises a surgeon console, remote surgical robot, and a control unit. The surgeon console comprises a base connected to a hand controller by a linkage, the linkage comprising a plurality of joints whereby the configuration of the linkage can be altered. The surgeon console comprises a driver to drive each joint to move. The surgeon console further comprises a presence sensor to sense the presence of a surgeon's hand on the hand controller. The control unit receives user inputs from the hand controller, converts the received user inputs into command signals for driving manipulation of the surgical robot, receives sensory inputs from sensors including the presence sensor, and responds to, during a surgical operation, concurrently detecting from the received sensory inputs (i) the lack of a surgeon's hand on the hand controller, and (ii) an external force additional to gravity acting on the hand controller, by controlling the drivers to drive the joints with a damped response in the direction of the external force.

    Abstract: A mechanical advantage device includes a base, a beam pivotably connected to the base at a fulcrum between a first end of the beam and a second end of the beam, a seat at the first end of the beam, and a load at the second end of the beam. In some embodiments, the mechanical advantage device includes structure, such as a linkage, for effecting oscillation of the beam by shifting weight along the beam. The mechanical advantage device may be a single-person seesaw. In some embodiments, the mechanical advantage device may be used to move a car or to generate power.

    Abstract: An uninterruptible power supply includes an input configured to be coupled to a renewable power source and an energy storage component configured to receive and store energy and to provide stored power. Power circuitry is configured to receive the renewable power and the stored power and provide output power to a load. A controller coupled to the power circuitry determines whether an amount of available renewable power exceeds the output power level provided to the load and, if so, provides excess power from the renewable power to the stored energy component.
