Dynamically Variable Spot Size Laser System

Applications include aerospace engine repair, medical hardware manufacturing, plastic mold and die restoration, and jewelry manufacturing and repair.

NASA’s Marshall Space Flight Center developed the handheld laser torch, designed for welding and brazing metals, to repair hard-to-reach Space Shuttle engine nozzles. It incorporates various manual controls and changing lenses to allow the operator to adjust the laser’s power output in real time. The controls and lenses are designed to increase precision, portability, and maneuverability as compared to existing automated lasers and traditional welding techniques such as tungsten inert gas (TIG), metal inert gas (MIG), or gas-tungsten arc welding (GTAW) systems. Proximity sensors with automated shut-off switches also ensure a high level of safety for the user.

Precision Coffeemaker Adapts Brews to Beans and Taste

NASA’s embedded communications technology and PID controllers play key roles in coffee brewing system.

Technology often takes circuitous paths. A magnetron developed for precision bombing during World War II led to the microwave oven, and a battery-powered drill created for collecting samples of Moon rock gave birth to the Dustbuster. Likewise, one student’s NASA experience with autonomous robotic vehicles has informed the creation of one of the world’s most sophisticated coffee machines.

2016 Create the Future Design Contest: Machinery/Automation/Robotics Category Winner

SHAPE MEMORY ALLOY BASED SAFETY LATCH

Nicholas W. Pinto, Suresh Gopalakrishnan, Chandra S. Namuduri, Nancy L. Johnson, and Mark Vann General Motors, Warren, MI

General Motors has invented a device that indicates when an unsafe level of energy remains in an electrical panel box after the main power has been disconnected. Possible sources of this energy may be incorrect wiring, external device add-ons, and the presence of residual charge from capacitors. The device works by engaging a safety latch mechanism built with shape memory alloy (SMA) technology along with an audio or visual alarm.

2016 Create the Future Design Contest: Consumer Products Category Winner

MIFOLD

Jon Sumroy, Carfoldio, Ltd., Ra’anana, Israel

“The award is a true accolade from design and engineering professionals. This means that, as well as solving a serious problem with a convenient, practical, and affordable solution, we have solved the problem in a well designed and engineered way. The credibility of the contest, and the respect and professionalism of the organizers and judges, will enhance our ability to market the Grab-and-Go Booster Seat worldwide. This will help us keep more children safer in more journeys, more of the time.”

The mifold Grab-and-Go booster seat for children aged 4-12 is more than ten times smaller than a regular booster seat and just as safe. A regular booster seat works by lifting a child up to the position of an adult. mifold does the opposite, securing the seatbelt in the correct position on the hips and shoulder by holding the seatbelt down at three points.
