Abstract: A smart connector system includes a machine connector disposed on a face of a surgical machine, an illumination ring located on the face of the surgical machine and disposed around a periphery of the machine connector, an RFID reader antenna located in close proximity to the machine connector and the face of the surgical machine, and an accessory connector adapted to couple with the machine connector. The accessory connector has an RFID tag antenna and is capable of attaching a tool to the surgical machine. When the accessory connector is brought within close proximity to the machine connector, a communications connection is established between the RFID tag antenna and the RFID reader antenna.

Abstract: A fluid coupling with a rotating outer collar includes keys or tabs which engage keyways or slots to prevent rotation of the outer collar.

Abstract: A foot controller for a microsurgical system that includes a body, a switch disposed on the body, and a switch guard coupled to the body and disposed in a spaced relationship to an outer surface of the switch.

Abstract: A footswitch with a tiltable treadle for a first linear control input enables a second linear control input by use of a radial slider assembly positioned on top of the pedal treadle. Movement of the radial slider assembly provides a second linear control input to a potentiometer.

Abstract: An ergonomic footswitch having a substantially planar tiltable treadle positioned on a base enables up and down or pitch movement of the substantially planar footswitch around an axis of rotation located at the substantially horizontal rotational axis of an operator's ankle.

Abstract: A footswitch having a tiltable treadle includes a rotatable heel cup for providing a second proportional control input based on the rotational movement of the rotatable heel cup.

Abstract: An automatic dry food feeder for animals is described. The feeder consists of a housing with a hopper fitted in the housing having sloping members terminating in a rectangular section at the bottom of the hopper. An electric motor having a gearbox attached thereto is located outside the rectangular portion of the hopper. The gearbox shaft extends into the rectangular portion with a sleeve fitted over the shaft. Attached to the sleeve are segmented flexible vanes that rotate in accordance with the signal provided by an electronic programmable controller. Rotating the segmented flexible vanes a prescribed amount in response to a programmed timer dispenses a measured amount of dry animal food into a tray.
