PHOTONIC ANALOG-TO-INFORMATION RECEIVER SIGNAL PROCESSING: a very interesting thesis from Naval Postgraduate School on EW Nyquist Folding Receivers (NYFR) and their implementation using Photonic Components #EW#Wideband Receivers#Nyquist Folding https://lnkd.in/dmYrx6rm

JASA Measurements with balloon-borne sensors deviate from the ambient infrasonic field due to wave diffraction on the balloon; these distortions can be exploited to increase sensor sensitivity. https://lnkd.in/gc592vub Naval Postgraduate School #acoustics

Congratulations to Naval Surface Warfare Center Carderock Division (NSWCCD) inventors Chidubem (Arthur) Nwokoye, JinHyeon Yoo, and Nick Jones who were granted U.S. Patent No. 12,158,511 B1 on yesterday titled “Magnon Excitation and Detection Systems, Apparatus, and Methods”.   This invention is for magnon excitation (production) and detection systems. Magnons are quantized collective oscillations (waves) of the precession of magnetic moments of atoms in a magnetic field.   The invention describes a system for modulating, digitizing, sending data, and communicating via these magnetic spin waves.  This type of innovation in our Navy R&D ecosystem is what keeps us leading the way.  #patents #innovation #NavalSTEM #DoDInnovates #DoDFutures #CarderockROCKS

It's time for #TuesdayTrivia! Test your knowledge with today's question from Travis McGriff, a 7th grade science teacher at Sun Valley Middle School. What is the name of the atmospheric layer in which military aircraft fly? (Hint: It is different from the atmospheric layer in which commercial planes fly). A. Exosphere B. Mesosphere C. Thermosphere D. Stratosphere

📣 CALL FOR PROPOSALS 📣 The proposal window is now open for the 22nd Annual Acquisition Research Symposium & Innovation Summit, scheduled for May 7-8, 2025. Deadline for paper and panel proposals is November 18. Learn more & submit proposals at www.researchsymposium.com. This year, the symposium is combined with an Innovation Summit under the overarching theme of "Transitioning Technology." The goal of this dual event is to explore and promote innovative ways to #transitiontechnology from research and development to programs of record to support the warfighter. The Innovation Summit will take place May 8, featuring panels designed to enhance understanding of current, past and future #innovation efforts across the defense innovation ecosystem. These panels will be composed of stakeholders from across academia, industry and government, bringing together diverse perspectives and areas of expertise. The Symposium is sponsored by the Acquisition Research Program at Naval Postgraduate School, Department of Defense Management at Naval Postgraduate School, Naval Warfare Studies Institute at Naval Postgraduate School, and the Naval Postgraduate School Foundation & Alumni Association. #Acquisition #Collaboration #defenseindustry #innovationsummit

The Maritime Environment for Training and Analysis (META) proposed project is set to revolutionize naval training by generating realistic electromagnetic signatures in a dynamic virtual environment. META will enhance warfighter readiness for the complexities of the electromagnetic spectrum at sea. Read the article and white paper: https://buff.ly/3DinDAo #META #NavalTraining #ElectromagneticSpectrum #LVC #Simulation #DefenseTechnology #Terasynth

As robot-human teams begin to make their way to the modern battlefield, maintaining a full picture of the electromagnetic spectrum (radio waves, radar systems, and every other invisible communication type) becomes exponentially more important. We're building the tools that make simulating and visualizing EMS for both training and operations.

#TechTuesday Joystick Remote Control Circuit Patent In 1926, the U.S. Naval Research Laboratory's C.B. Mirick patented his system for remote radio control of pilotless aircraft (or of "any circuits or objects which are to be controlled at a distance") using a " 'joy stick' identical with the 'joy stick' provided in aircraft." U.S. Patent no. 1,597,416, "Electrical Distant-Control System," Aug. 24, 1926. "my invention relates broadly to distant control systems, and more particularly to a control circuit for a radio transmitter, and a selectively responsive circuit for a radio apparatus whereby particular controls may be caused to function individually or simultaneously."

Ocean Power Technologies CEO Philipp Stratmann joined Steve Darling from Proactive to share news regarding the company's progress on its innovative PowerBuoy system for the Naval Postgraduate School. The primary assembly of the PowerBuoy, equipped with AT&T® 5G technology and advanced subsea sensors, is now complete. Integration of OPT’s Merrows suite, which offers AI-driven Maritime Domain Awareness, has also been finalized. Watch at #Proactive #ProactiveInvestors http://ow.ly/3Tp4105Snkw
