Abstract: A device to regulate tension of an actuation element for actuating movement of a surgical instrument includes an elastically deformable body configured to be coupled to the actuation element. The deformable body is configured to elastically deform in response to a state of slack occurring in the actuation element. As slack occurs in the actuation element, the deformable body is configured to divert a path of the actuation element to accommodate the slack so the path of the actuation element differs from an axis the actuation element follows prior to the actuation element developing slack. A force transmission mechanism for a teleoperated surgical instrument includes a chassis, an actuation input mechanism, an actuation element, and a tension regulator coupled to the actuation element to compensate for slack of the actuation element.

Abstract: A data acquisition device includes measuring instruments to generate physiological and/or psychological data streams. Microprocessors within the acquisition device process the generated data streams into metrics, which feed into stress function algorithms. Algorithm processing may occur either on the device, or metrics may be communicated via wireless communication for external processing on mobile devices and/or cloud-based platforms. The calculated stress functions inform cloud-based computational systems biology-derived models describing the dynamics of hormones and neurotransmitters released in the body in response to stressful stimuli. Stress hormone levels are quantified using these models, and are used in combination to serve as biologically inspired metrics of acute and chronic stress an individual is experiencing.

Abstract: Cardiac repolarization activity can be mapped using action potential duration (“APD”) and/or activation recovery interval (“ARI”). APD can be measured using a bipolar electrogram signal measured, for example, using a monophasic action potential (“MAP”) catheter. ARI can be measured using unipolar electrogram signals. The electrogram signal is used to identify a depolarization tick time. A repolarization tick time can be identified using either a point in time when the electrogram signal passes below a threshold or via local maxima and minima of a first derivative of the electrogram signal. Diastolic intervals can also be computed using depolarization and repolarization tick times.
