Motor Controller Provides Custom Electronic Control Solution

A Fortune 200 company needed a turnkey, DC voltage, agency-compliant electronic control solution capable of providing motion control with memory position capabilities and auto run/sense features for a multi-motor application involving four motors. Particularly important to the design criteria was the development of an interactive system of wireless remote control capabilities and other user interface devices, including iPhone and iPad interconnect devices. It was a complicated job, and the company would need to partner with experts who could deliver a time- and cost-effective solution.

NASA Sensor Supports Flexible Aircraft Design

A NASA-developed fiber optic sensor provides the kind of detailed feedback that could guide the direction of flexible wings and other next-generation aerospace parts. The multi-core fiber (MCF) contains light reflectors, known as fiber Bragg gratings, that reveal shape and position in three dimensions.

Multiphysics CAE of a Shock Absorber

Figure 1. CAE simulation of a shock absorber. Shock absorbers are important parts of vehicles. The shock absorber is used to observe the vibrations from shock loads due to irregularities of the road surface, and operates without affecting the stability, steering, or handling of the vehicle. Generally, for light vehicles, cylindrical coil springs are used as suspension elements. The application described in this article attempts to analyze performance of a shock absorber with different suspension springs. This analysis includes comparative modeling and analysis of solid height, damping performance, oscillation capabilities of closed coil conical and cylindrical compression springs, and a suggested suitable design for improved performance.

Machine Vision System Measures ‘Drops’ in Citrus Grove Health

A University of Florida Institute of Food and Agricultural Sciences researcher has developed a machine vision system to measure the quantity of a citrus grove’s dropped and decayed oranges. The fallen fruit provides an indication of a so-far incurable disease that has been spreading through Florida’s trees since its first appearance in the state in 2005.

Creating Advanced Dosimeters Requires Thorough Inspection of Small Components

The McMaster University students will launch the small satellite into low Earth orbit to study the effects of ionizing radiation on the human body. Recent advancements in space technology have resulted in space exploration becoming a rapidly growing field, and the desire for human space exploration is drastically increasing. Previous manned missions include flights to low Earth orbit (LEO), such as to the International Space Station (ISS); however, upcoming flights are planned to go beyond LEO, such as to asteroids and eventually Mars. A major consideration in such missions is that the space environment is significantly different from that of Earth, especially with respect to the radiation environment. This drastic difference results in concerns regarding radiation dose.
