Abstract: An external fixation system may include first and second fixation rings and a plurality of adjustable length struts. Each adjustable length strut may have two joints, a rod, a tube, and an actuator configured to drive the rod axially relative to the tube to change an effective length of the strut. The system may include a plurality of controller modules each configured to couple to a corresponding strut. The external fixation system may have a manual mode of operation in which the controller modules are not coupled to the struts, and manual actuation of the actuators changes the effective lengths of the struts in discrete length increments. The external fixation system may have an automated mode of operation in which the controller modules are coupled to the struts, and automated actuation of the actuators changes the effective lengths of the struts in infinitesimally small length increments.

Abstract: A system for processing patient data associated with a joint of a patient. The system comprising a computing device executing instructions to generate a 3D patient bone model of the joint in a non-weighted pose. The instructions rearrange 3D first and second bone models in order to mimic a weighted pose of the joint of the patient from a 2D image of the joint of the patient in a weighted pose by performing the steps of: generating a plurality of 2D projections of poses of the 3D patient bone model; comparing the plurality of 2D projections to contour lines of the first bone and the second bone in the 2D image; identifying particular 2D projections that best-fit a shape and size of the contour lines; and arranging the 3D first and second bone models relative to each other according to orientations represented by the particular 2D projections that were identified.

Abstract: Embodiments of the invention are directed to a release device that uses an electro-mechanical mechanism instead of an explosive to deploy a deployable unit such as a flight data recorder. In one embodiment of the invention, a solenoid is activated that causes a piston surrounded by the solenoid to move which moves a pin attached to the piston and allows a spring to decompress and deploy a deployable unit. In some embodiments, a release actuator mechanism, a pneumatic actuator mechanism, a shape memory alloy or a combination thereof may be used to affect deployment of the deployable unit.

Abstract: An evoked potential monitoring system including a control unit having stimulator circuitry and a probe assembly coupled to the control unit. The probe assembly includes a stimulus probe and a stimulator handpiece selectively coupled to the stimulus probe. The handpiece includes a handle, control circuitry, and a switch. The control circuitry is electrically coupled to the stimulator circuitry. The switch is electrically coupled to the control circuitry and extends to an exterior portion of the handle. In this regard, movement of the switch remotely controls the stimulator circuitry to continuously increment or decrement a stimulation energy level delivered to the stimulus probe over a series of discrete, incremental steps.

Abstract: An intraoperative neural monitoring system includes a power source and a simulator powered by the power source to deliver a cycle of electrical stimulation to a patient as a first group of positive or negative phase pulses automatically followed by a second group of pulses of opposite phase or polarity to the pulses of the first group. An activation performed to initiate delivery of the first group of pulses is effective to deliver the entire cycle of stimulation. A method of intraoperative neural monitoring involves activating a simulator to deliver a biphasic cycle of electrical stimulation to a patient during an operative procedure, delivering the entire cycle of electrical stimulation to the patient in response to the activating step and detecting EMG activity in the patient.
