This document describes the development of an image-guided surgical system for intracranial neurosurgery. It includes a web-based software for surgical planning and a mechanical arm to position surgical probes. The software allows uploading of MRI/CT scans and viewing the target in 3D. The articulating arm has 5 degrees of freedom, maintains sterility, and locks probes with sub-2mm accuracy. Testing showed the prototype meets accuracy standards and is substantially cheaper than current methods, with potential to further reduce costs through optimized manufacturing. The system was approved by consulted neurosurgeons.
This is a danish "HOW TO" guide by the danish web agency morningtrain.dk.
This slideshow covers the basics of learning SASS, and after reading through the slides, you should be able to start writing SASS yourself.
As mentioned earlier, the slideshow is in danish, because there is already tons of english "How to SASS" guides, and the SASS documentation page is also well explained.

Sadie Zeller, Manager of Global Product Management and the Clinical Vertical Market at Microscan Systems, presents the "Another Set of Eyes: Machine Vision Automation Solutions for In Vitro Diagnostics" tutorial at the May 2017 Embedded Vision Summit.
In vitro diagnostics (IVD) are tests that can detect diseases, conditions, or infections. The use of automation, including machine vision inspection, in IVD has increased steadily, and is now a standard practice. Vision-based laboratory automation enables greater throughput efficiency and minimizes the risk of human error. But IVD is a challenging application: the healthcare industry requires systems that are, at a minimum, fail-safe, and ideally, error-proof.
Machine vision systems for IVD (and related life sciences) therefore require a robust development phase including an iterative design-validate process to ensure that the system is safe for use. This presentation addresses some of the key requirements and constraints of healthcare vision applications, and highlights approaches for application design and testing to meet tough industry demands.
Discover a completely integrated surgical imaging workflow through the use of Stryker SDC surgical cameras and DataMediatOR with Cerner Millennium. Using these tools, surgeons have an automated and secure way to capture images during procedures, and then share the images with patients and other providers. During this panel, we will discuss the value and simplicity of a surgical imaging project and provide detailed information specific to the implementation and integration of these two systems and its hardware.
Use of Machine Intelligence in manufacturing industry poses a special challenge due to a wide range of use cases, inherent complexity in data collection, availability of information and disconnect between information islands in different manufacturing steps.
Within our talk we present several machine intelligence projects we did in the manufacturing industry, which helped our customers in product quality improvement, reduction of cost and better asset management. We will talk about the used methodologies, the results achieved and the lessons learned from these projects. We will specifically focus on the importance of process and business knowledge for successful implementation of any industrial project.

This presentation helps technical communicators face challenges in agile planning and execution. It’s increasingly common for writers to work on multiple agile teams. The session includes tips for better communication and teamwork on your agile team, with the goal of a “whole team approach” in mind.
Kent Melville and Annie Wise from Inductive Automation, and water/wastewater controls professionals Henry Palechek and Jason Hamlin, cover 10 steps for building a sustainable SCADA system that survives and even thrives using only your operational expenditure budget.
You'll learn about:
• What type of hardware and operating systems to use
• Utilizing smart devices and MQTT
• The advantages of server-centric architecture and web-based deployment
• Rapid development with templates and UDTs
• Powerful alarming and reporting tools

Transcat Webinar: :Suitability Of Instruments: Presented By: Howard ZionTranscat
Join us as Howard Zion, Transcat's Director of Service Application Engineering, discusses the process of selecting instruments that are suitable for the measurements on your products or in your manufacturing processes. This webinar, entitled “Suitability of Instruments”, will teach you the different aspects of determining suitability, including:
• Parameter, Range, Resolution, Accuracy?
• How Process Tolerances factor into the decision
• Some new terms: Process Accuracy Ratio (PAR) and Process Uncertainty Ratio (PUR)
• Other factors that can lead to false measurement results: Operator influence, Storage/Handling/Transportation influence, etc.
