Abstract: The stress field of steel members in service is unevenly distributed under complicated loads. The existing single-path ultrasonic (SPU) sensors can only measure stress in a single ...

Abstract: This paper presents the pulmonary acoustic sensor telemetry array, a novel hardware prototype developed for remote pulmonary monitoring, diagnosis, and prognostication of pulmonary sounds in ...

Space, in military parlance, is “the ultimate high ground.” And for years, the Pentagon has mused about ways to orbit a radar from high above, to look down on adversary aircraft and catch them out in ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...

Four small satellites rode a Rocket Lab Electron launch vehicle into orbit from Virginia early Thursday, beginning a government-funded technology demonstration mission to test the performance of a new ...

CALGARY — Researchers at the University of Calgary's space weather network have attracted the attention of Canada’s military, the U.S. Navy and NATO with their eyes on the sky. They run 22 ...

AutomationDirect has added ifm fail-safe inductive sensors featuring two OSSD outputs that can be connected to a safety relay for safety applications requiring the detection of metal objects. These ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

SICK is opening up new possibilities for virtual engineering with NVIDIA technologies. MINNEAPOLIS, Oct. 3, 2025 – Having provided more digital sensor models of 2D and 3D LiDAR sensors, safety ...
