Abstract: Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include an inner member having a stent receiving region, a stent disposed along the stent receiving region, a deployment sheath axially slidable relative to the inner member, the deployment sheath having a proximal end region, a handle coupled to the deployment sheath, a rod coupled to the handle, the rod having a distal end region, a proximal end region and a first threaded portion extending from the distal end region to the proximal end region and a coupling member configured to couple the rod to the deployment sheath, the coupling member having an engagement portion. Additionally, the first threaded portion of the rod is designed to engage the engagement portion of coupling member and rotation of the rod is designed to translate the coupling member along the rod.

Abstract: A method and apparatus for machine learning model based fraud detection of transactions are described. The method may include determining, by a fraud detection system, a first block rate of a first fraud detection machine learning model (MLM) that scores transactions of a server computer system, wherein the fraud detection system blocks a transaction when a score generated for the transaction by the first fraud detection MLM does not satisfy a first threshold value. The method may also include accessing, by the fraud detection system, a second fraud detection MLM to be used by the fraud detection system for blocking future transactions. Furthermore, the method may include determining, by the fraud detection system, a second threshold value using a set of prior transactions input into the second fraud detection MLM that results in a second block rate of the second fraud detection MLM within a predetermined margin of the first threshold.

Abstract: A system may include a controller that may control operations of a device according to a control loop and characterize a frequency response of the device while the device is operating. The controller may characterize the frequency response by adding a perturbation signal to any signal in the control loop. The controller may then determine a first transformed signal by performing a first discrete Fourier transform on a first signal in the control loop at a frequency of the perturbation signal and determine a second transformed signal by performing a second discrete Fourier transform on a second signal in the control loop at the frequency of the perturbation signal. The controller may then determine the frequency response at the frequency by comparing a first amplitude and a first phase of the first transformed signal to a second amplitude and a second phase of the second transformed signal.

Abstract: Techniques for creating 3-D movies allow improved control over camera positioning parameters and editing of depth in post-process to provide for a smoother variation in the viewer's convergence distance and a more pleasant viewing experience. A director can define reference parameters related to a desired viewing experience, and camera positioning parameters are derived therefrom. A depth script specifying piecewise continuous variations in reference parameters can be applied in post-process to generate 3-D shots, scenes, or movies. These techniques can be applied in both computer-generated and live-action 3-D movies.

Abstract: An approach is disclosed for generating stereoscopic image sequences. The approach includes receiving a plurality of image sequences, each image sequence captured from a distinct camera or other capture device in a multi-camera array. One image sequence is a primary image sequence and the other image sequences are secondary image sequences. The approach further includes generating, from the primary and at least one or more of the secondary image sequences, depth maps corresponding to images of the primary image sequence and generating, for each image in the primary image sequence, based on at least the depth maps and the corresponding images of the primary image sequence, stereoscopic images of a stereoscopic image sequence.
