Abstract: A surgical console having a panel display mounted on a three-axis gimbel that permits articulation of the panel display via swivel, spin and tilt axes. The articulation mechanism uses two helix cable wraps with a single continuous cable that allows for large rotation of the panel display. The continuous cable simplifies construction and minimizes the electrical signal noise to the panel display.

Abstract: A control system for a brushless DC motor responsive to digital control signals is disclosed. The motor includes a multiphase wound stator and a permanent magnet rotor. The rotor is arranged so that each phase winding, when energized from a DC source, will drive the rotor through a predetermined angular position or step. A commutation signal generator responsive to the shaft position provides a commutation signal for each winding. A programmable control signal generator such as a computer or microprocessor produces individual digital control signals for each phase winding. The control signals and commutation signals associated with each winding are applied to an AND gate for that phase winding. Each gate controls a switch connected in series with the associated phase winding and the DC source so that each phase winding is energized only when the commutation signal and the control signal associated with that phase winding are present.
