Scientists Fit Light-Emitting Bioprobe in a Single Cell

If engineers at Stanford have their way, biological research may soon be transformed by a new class of light-emitting probes small enough to be injected into individual cells without harm to the host. Welcome to biophotonics, a discipline at the confluence of engineering, biology and medicine in which light-based devices – lasers and light-emitting diodes (LEDs) – are opening up new avenues in the study and influence of living cells. This is the first study to demonstrate that tiny, sophisticated devices known as light resonators can be inserted inside cells without damaging the cell. Even with a resonator embedded inside, a cell is able to function, migrate and reproduce as normal.

Students Drive Effort To Introduce “Smart Lighting” on Rensselaer Campus

An effort by students, faculty, and staff at Rensselaer Polytechnic Institute to install ultra-efficient LED light bulbs in one campus facility will save the university approximately $21,000 per year. Along with creating opportunities for reduced energy consumption and further cost savings in the future, the project is an important first step toward transforming the entire campus into a real-world laboratory for the emerging field of “Smart Lighting.”

LEDs Allow Home Lighting System Control Using Smartphone or Tablet

Philips recently unveiled what it claims is the world’s smartest web-enabled LED home lighting system. Philips hue allows you to create and control the light in your home using your smartphone or tablet. A starter pack includes three bulbs that screw into your existing lamps, and a bridge that can be plugged into your home Wi-Fi router. Then you simply download the hue app to operate the system.

Small Form Factor Computers Go Ultra-low Power

Agrowing number of mobile, space constrained or harsh environment applications are being designed for the military, industrial automation/HMI, digital signage and medical markets that are driving the need for ever-lower power consumption. These embedded systems have been underserved by existing SFF platforms that have not been able to offer ultra-low power operation, many times below 3 Watts, in a slim profile design. OEM developers have also been challenged to find computing platforms that deliver a flexible and scalable solution in terms of performance and rugged reliability with state-of-the-art interface and graphics support that mimics the same functionality as today’s smart consumer devices.

Carbon Nanotube Technology Promises a Revolution in Electrical Cabling

While carbon nanotube technology (CNT) has generated widespread interest for applications ranging from semiconductors to medical, one area that is a focus of research at TE Connectivity is high-performance electrical cables. TE has been actively researching CNT for wire and cable, including cooperative efforts with universities and industry leaders, and has prototype samples for evaluation. While there is still much progress to be made before CNT cables become main stream, we believe the technology is sufficiently advanced to meet specific niche applications such as satellites.

Robotic Accuracy Improves Aerospace Manufacturing

Where accuracy is concerned, robots have traditionally relied on repeatability. In the past, robotic accuracy has not been developed to a level of maturity acceptable to standard production processes. Critical aerospace manufacturing techniques such as fastening and drilling were historically not held to tight tolerances. Typical tolerances for airframe assembly fastening were in the +0.030" range. The standard is set by the positional requirement for drilling of fastener holes, which is a key target application for robotics in manufacturing.

A New Era in Automotive Design Requires a New Era in Simulation Tools

Automotive design is going through one of its most profound changes since the gasoline engine eclipsed steam power. Fuel prices and growing environmental concerns have made efficiency the biggest prerogative in vehicle design since the gas shocks of the early 1970s. President Obama’s 2011 agreement with 13 large automakers to increase the CAFE (Corporate Average Fuel Economy) standards from 27.5 miles per gallon for cars and light trucks today, to 54.5 miles per gallon by 2025, will affect vehicle design priorities throughout the automotive industry.

SAE World Congress Preview “Achieving Efficiency”

The 2013 SAE World Congress and Exhibition, taking place April 16-18 at Cobo Center in Detroit, represents an unparalleled opportunity to explore new technology through both technical sessions and the Innovators Only Exhibition. This year’s Host Company is Chrysler, and ZF will serve as Tier One Strategic Supplier for the event. Last year, more than 9,000 engineers, engineering managers, auto industry executives, and government officials from 45 different countries attended the SAE World Congress (sae.org/congress).

High-Pressure Systems Suppress Fires in Seconds

Orbital Technologies Corp. (ORBITEC) of Madison, WI, has been a longtime NASA partner, working with the Agency on numerous projects, many through the Small Business Innovation Research (SBIR) program. ORBITEC collaborated with Marshall Space Flight Center to develop products such as a cool-wall vortex combustion chamber that represents a new method of rocket engine design. By feeding liquid or gas oxidizer into the combustion chamber in a manner that generates a swirling vortex flow, the design confines the mixing and burning of the propellant to the core of the chamber, keeping the walls free from volatile thermal stresses. ORBITEC applied this innovation to an advanced vortex hybrid rocket engine that combines solid and liquid fuel to power a low-cost, highly reliable, and versatile propulsion option.

Building an Immersive Training Platform for Infantry Soldiers

Developing an effective immersive training tool requires a fine balance of technology capabilities with human factors. Achieving a training goal to build squad leadership skills, squad-level communication, and mission rehearsal for an entire squadron brings together several components, including advanced body sensors that must translate physical movements, avatar actions, and high-resolution headmounted displays (HMDs) to immerse the user in the virtual world.
