  • ARTICULATING DRILL SYSTEM
    Publication number: 20220192761
    Abstract: An articulating drill system is provided that includes a hand-held portion and a drill portion. At least two actuators are provided for controlling at least two axes of the drill portion. In some embodiments, a tool is provided with the drill portion and adapted to interact with patient tissue. The drill portion can be modified to include at least two rigid objects in communication with the actuators and attached to the drill portion. The system can be used to make any linear cut within a deviation of ±1.0 mm and ±1.0°, or better in patient tissue.

  • SYSTEM AND METHOD TO TRACK A RESPIRATORY CYCLE OF A SUBJECT
    Publication number: 20080243018
    Abstract: A system operable to track a respiratory cycle of a subject is provided. The system includes at least a first sensor positioned on the subject, and at least a second sensor located at a reference relative to a change in position of the first sensor associated with respiration of the subject. The system also includes a respiratory cycle measurement device coupled to receive the position data of the first sensor relative to the reference. The respiratory cycle measurement device is configured to translate the position data of the first sensor relative to time into a respiratory signal representative of a respiratory cycle of the subject.
