Algorithm Magnifies Motions Indiscernible to the Naked Eye

MIT has been investigating techniques for amplifying movements captured by video, but indiscernible to the human eye. The algorithms can make the human pulse visible and even recover intelligible speech from the vibrations of objects filmed through soundproof glass. A new version of the algorithm can amplify small motions even when they’re contained within objects executing large motions. So, for instance, it could make visible the precise sequence of muscle contractions in the arms of a baseball player swinging the bat, or in the legs of a soccer player taking a corner kick.

Robots Learn to Observe, Adjust Their Force, and React


When robots and humans have to work together, it often leads to problems. Researchers on the CogIMon project want to teach robots to understand the forces during the movement of an object, and how to appropriately react to changes in weight or contact with the object while carrying it. Humans have no problem estimating the weight of an object, but robots lack this ability.

Tests Show Football Player Concussions are Caused by Different Head Motions

When modern football helmets were introduced, they all but eliminated traumatic skull fractures caused by blunt force impacts. Mounting evidence, however, suggests that concussions are caused by a different type of head motion, namely brain and skull rotation. Stanford engineers have produced a collection of results that suggest that current helmet-testing equipment and techniques are not optimized for evaluating these additional injury-causing elements.

What is Wiring Synthesis?

Wiring synthesis is a transformative technology for vehicle wiring design. Using principles of Model Driven Systems Engineering (MDSE), wiring synthesis automatically generates detailed vehicle wiring design data from simpler, higher level inputs. Totally different from traditional wire routing, wiring synthesis addresses key domain problems such as high frequency design change, arduous configuration management, design quality and verification, and development cost and cycle time. Supported by ten years of software development, major automotive OEMs and suppliers in Europe, USA and Asia have now applied wiring synthesis technology with great success. As electrical complexity continues to grow, wiring synthesis will become the only practical way to design automotive electrical systems.

Optimizing Automotive Wiring Designs Using Engineering Design Automation

Currently, most methods for optimizing an Electrical Distribution System employ unsophisticated and manual spreadsheet tools. Any detailed feedback on critical metrics such as cost or weight typically relies on another organization and requires weeks or months. The resulting EDS is inevitably sub-optimized, not due to a lack of engineering ability, but rather the tools available. To ensure that the EDS design is optimized from the outset, the design environment itself must be enhanced. This paper will discuss the four key requirements for an EDA system along with the flow implications using examples from the Mentor Graphics Capital suite.

Technology To Speed Wire Harness New Product Introduction

The speed with which wire harness makers can bring new or changed designs into production is a key business differentiator. Up until now, the complex sequence of tasks necessary to accomplish such a feat was poorly supported by COTS software. A robust COTS solution from Mentor Graphics is now available. This paper focuses on a set of manufacturing disciplines and describes key “building blocks” which underpin Mentor’s robust software solution for harness wire manufacturers. The Mentor approach protects company IP, reduces manufacturing engineering costs, improves process quality, and provides early and accurate visibility of gross margins. More importantly, it removes critical path bottlenecks to new product introduction.

940nm VCSEL Array

Princeton Optronics (Mercerville, NJ) has introduced high-power (8W) 940nm VCSEL arrays for illumination applications. These arrays have an efficiency of >45%, a spectral width of approximately 1nm and a circular beam with divergence of 18 degrees (full angle). The array’s dimensions are 2x2mm and it is normally mounted on submounts.
