Coming Soon - High-Speed Imaging: More Than Just Pretty Pictures

We have all seen slow-motion replays in sports broadcast, as well as on TV commercials and popular YouTube channels. Myths have been debunked, water balloons popped, and bullets shot. Watching slow-motion replay of very fast phenomena has led to deeper scientific understanding and breakthrough discoveries. But, there is more to high-speed imaging that slow-motion playback. Camera systems can be integrated with data acquisition to allow the correlation of external measurements to visual feedback; motion analysis tools in playback software can use data in the image to calculate speed, acceleration, angles, and more. And, tracking points in a slow-motion playback can lead to additional visual insights.

Will You Use A Speed-Reading App?

Spritz, a Boston-based software developer, claims that users of its technology can read up to 1,000 words per minute (wpm) via its new technology. At that rate, readers could finish a 300-page novel (like Harry Potter and the Sorcerer's Stone, as the Huffington Post noted) in less than 90 minutes. The app, optimized for small screens and set to be released soon with the Samsung Galaxy S5 and Samsung Gear 2, presents just one word at a time, each aligned by an "Optimal Recognition Point." The technology keeps the eye focused on the fixation point typically found just left of center in a word.

NASA Data Helps Growers During California's Drought

Following two consecutive years of drought conditions, 2014 is shaping up to be one of the driest years on record in California. Since 1982, the California Department of Water Resources (CDWR) has operated more than 140 monitoring stations that provide daily measurements of agricultural weather conditions and the amount of water lost to the atmosphere by a well-water grass surface. Data from this network is distributed through the California Irrigation Management Information System (CIMIS), operated by CDWR. To date, this information has been shown to have great value as a tool for irrigation managers to determine the water requirements for their crops.

Researchers Mass-Manufacture Using Compostable Material

Researchers at Harvard's Wyss Institute have developed a method to carry out large-scale manufacturing of everyday objects — from cell phones to food containers and toys — using a fully degradable bioplastic isolated from shrimp shells. The objects exhibit many of the same properties as those created with synthetic plastics, but without the environmental threat. The process also trumps most bioplastics on the market today in posing absolutely no threat to trees or competition with the food supply.The Wyss Institute team developed its bioplastic from chitosan, a form of chitin, which is a powerful player in the world of natural polymers and the second most abundant organic material on Earth. Using traditional casting or injection molding manufacturing techniques, the researchers process the material so that it can be used to fabricate large, 3D objects with complex shapes. This advance validates the potential of using bioinspired plastics for applications that require large-scale manufacturing. The next challenge is for the team to continue to refine their chitosan fabrication methods so that they can take them out of the laboratory, and move them into a commercial manufacturing facility with an industrial partner.SourceAlso: Read other Manufacturing & Prototyping articles.

How Lean Manufacturing Adds Value to PCB Production

In an earlier paper, we established the importance of Design for Manufacturing (DFM) in today’s PCB manufacturing environment. PCBs designed using those techniques typically experience reduced failure rates, cost less to manufacture, and minimize waste during production.

Proposed Device Harvests Energy from Earth's Infrared Emissions

Physicists at the Harvard School of Engineering and Applied Sciences (SEAS) envision a device that would harvest energy from Earth’s infrared emissions into outer space.The research team is proposing something akin to a photovoltaic solar panel. Instead of capturing incoming visible light, however, the device would generate electric power by releasing infrared light.To show the range of possibilities, the group suggests two different kinds of emissive energy harvesters: one that is analogous to a solar thermal power generator, and one that is analogous to a photovoltaic cell. Both would run in reverse.The first type of device would consist of a “hot” plate at the temperature of the Earth and air, with a “cold” plate on top of it. The cold plate, facing upward, would be made of a highly emissive material that cools by very efficiently radiating heat to the sky. Based on measurements of infrared emissions in Lamont, Oklahoma (as a case study), the researchers calculate that the heat difference between the plates could generate a few watts per square meter, day and night.SourceAlso: Learn about the TIRS thermal infrared sensor.

Will Wearable Computing Improve Your Workouts?

A new technology called Moov wants to be your own personal trainer. A wearable fitness gadget, Moov analyzes an exerciser's form, offering real-time suggestions on how to improve workouts. The small, plastic disc attaches to a specfic body part that a wearer wants to analyze during a work: A runner can place the device in his or her shoe, for example, or a cardio-boxer can fit the technology on his or her wrist. By pairing with an app, the Moov tracks movement and body position to provide instant feedback and details about one's progress.
