International Classification:

G06F 3/0346
G06F 3/01

Abstract:

Method, apparatus, and systems for roll angle estimation for an input/gesture device (IGD) are disclosed. The method includes estimating a first axis vector of the input/gesture device (IGD) relative to the surface of the mobile device (MD), as a first frame of reference, using readings from a first type of sensor; and estimating the first axis vector of the IDG relative to a different, second frame of reference using a gyroscope integration of readings from the 3-axis gyroscope. The method further includes aligning the first axis vector of the IDG in the first frame of reference with the first axis vector of the IDG in the second frame of reference; minimizing a change in the alignment of the first axis vectors between the first frame of reference and the second frame of reference; and determining the roll angle of the IDG relative to the surface of the MD.

Abstract:

The present disclosure relates to devices, systems, and methods for evaluating and preserving arteriovenous access sites. More particularly, the present disclosure relates to a sensor wire that is sized, shaped, and configured to pass through a delivery instrument to measure pressure and flow within and around an AV access site, thereby indicating the impact of the arteriovenous access site on the blood flow to the surrounding vasculature and tissues in real time. Also, the present disclosure relates to a therapeutic system comprising a combination pressure-flow sensor wire, a balloon catheter with imaging capabilities, and a computer system to allow the user to evaluate the blood flow and blood pressure within and around an AV access site in real time, diagnose the presence of complications associated with arteriovenous access sites, treat such complications, and assess the effectiveness of treatment both during and after treatment.
