Taking Manufacturing Control By Force

In today's data-driven world, there's no such thing as having too much information. From a product manufacturer's perspective, there are countless variables that can impact their production process. Among these variables are changes in force, where the slightest contact can make a major impact on efficiency and quality.

One Plug-In Sensor Does Work of Many

Researchers have developed a sensor package that monitors multiple phenomena in a room using machine-learning techniques. The prototype contained 19 different sensor channels, including sensors that indirectly detect sound, vibration, motion, color, light intensity, speed, and direction. The sensor board is plugged in to a wall outlet, eliminating the need for batteries.

Determining Detection and Classification Potential of Munitions Using Advanced EMI Sensors in the Underwater Environment

Hazardous ordnance items are present along coastlines and in rivers and lakes in waters shallow enough to cause concerns for human recreational and industrial activities. The presence of water makes it difficult to detect and remove these hazardous legacies induced from wars, military training and deliberate disposal. Various techniques have been proposed to detect and characterize Unexploded Ordnances (UXO) and discarded military munitions (DMM) in the underwater environment including acoustic waves, magnetometery, and electromagnetic induction (EMI).

Compact Active Vibration Control System

NASA Langley Research Center has developed a point sensor and piezoelectric actuator system to actively sense and reduce vibrations in flexible structures. The system uses a directional piezoelectric actuator that couples to an underlying structure like four point forces acting normal to the structure. Four miniature accelerometers are located coincident with the piezoelectric point forces to create a matched actuator/sensor pair. This matched pair enables feedback control to be implemented using simple, robust, negative feedback that requires no knowledge of the dynamics of the structure, and can be implemented using analog electronics. When attached to a flexible structure, this active damping system can reduce vibrations in a variety of applications. Compared to other systems, this approach offers good performance with a simple and compact control system.
