The Department of Energy’s Savannah River National Laboratory (SRNL) developed the Smart Latch door latching sensor system to indicate whether or not a door is fully closed. The system, which attaches to a standard door, compares the audible signature of a door properly latching to every future instance of the door closing.
The system, developed by Bob Eakle, principal engineer for SRNL, uses a die-mounted VR Stamp speech recognition chip from Sensory Inc. to register the acoustic signature and a small transducer/microphone to pick up the sound. The housing, which according to Eakle is as small as a wrist watch, is constructed of polycarbonate material. When not in use, the Smart Latch “goes to sleep” to avoid draining its battery, and won’t “wake up” until initiated by the sound of the door.
The voice recognition chip is speaker dependent, which means it will ignore sounds that aren’t within the range of the acoustic signature. The chip was programmed with C. The Smart Latch is not available commercially yet, but the SRNL has made the license available through its technology transfer.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
