Acoustic sensing in forest environments

Army scientists developed a method and computational model to predict acoustic effects in forest environments due to atmospheric conditions.

The Army's new system provides comprehensive data on the entire forest environment. The technology is potentially applicable to commercial applications such as sound blast propagation or noise reduction.

Method of detecting and predicting lubrication loss in machinery

Army scientists recently invented a monitoring sensor that detects and predicts the failure of machinery due to a loss of lubrication.

Industrial facilities often suffer from lubrication-related equipment failure, with estimated costs in the U.S. of $1 trillion a year in reactive maintenance, unplanned downtime, and lost productivity.

The Army's method has been tested and validated by several experiments conducted by the inventors.

Nanocomposite pressure sensor

Army scientists developed a high spatial resolution, high-sensitivity pressure sensing system for dangerous and difficult-to-access locations. The patented technology is available via license agreement to companies that would make, use, or sell it commercially.

This technology addresses a need for a readily deployable sensor for dangerous or inaccessible locations, which can be used to probe a localized material response to pressure both at high spatial resolution and high sensitivity.

Drug testing device using hyperspectral imaging

An Army scientist developed a method for the detection of oxygen deficiency in the tissue of a human body as an indicator of illegal drug use without the need for touch or bodily contact.

The method relies on generating hyperspectral images and comparing them to a reference image. The comparison indicates whether the subject’s blood is oxygenated or deoxygenated.

Magneto-electric magnetic field sensors operating at low frequency

An Army scientist recently invented a field modulation technique that increases the operating frequency of a magnetoelectric (ME) sensor so that it has the capability of matching the mechanical resonance frequency of the sensor or alternatively solely increases the operating frequency.

The method may find utility in sensors used at security checkpoints to detect unapproved transport of banned items, as part of sensors in an unattended ground sensor network, to control manufacturing processes, to check the proper functioning of the hearts of babies before birth, and with drugs containing nanomagnets for monitoring of the dissemination of drugs in the body of patients using sensors.
