Our hacker [John Duffy] wrote in to let us know about a video he put together to explain the design of his open-source multimeter, the HydraMeter. If you’re interested in how the circuitry ...

Unlike expensive positron emission tomography (PET) scans or invasive lumbar punctures, the new blood test measures the ratio ...

Comparison of bone mineral density quantification in dogs using spectral detector computed tomography versus phantom-based conventional computed tomography ...

In this article here below, we present an electrical model for nanoscale spintronic radio frequency (RF) detectors called spin-torque diodes (STDs). A complete methodology for model parameter ...

The circuit is simple enough: it uses a capacitor, a resistor, and a pair of diodes (one of them a zener diode). He uses this basic circuit to drive simple regulators with input and output filter ...

These TVS diodes feature snapback characteristics with a 1.0 to 1.05 clamping ratio between the designated breakdown voltage and clamping voltage. The lower clamping voltage of the optimized snapback ...

To compare same-day photon-counting detector CT (PCD-CT) to conventional energy-integrating detector CT (EID-CT) for detection of small renal stones (≤ 3 mm).Patients undergoing clinical dual-energy ...

Background The patency of intracranial stents may not be reliably assessed with either CT angiography or MR angiography due to imaging artifacts. We investigated the potential of ultra-high resolution ...

The detector capacitance compensation (DCC) technique, which enables double active quenching of single-photon avalanche diode (SPAD), is presented in this article. A well-defined active quenching ...

Santa Clara, CA and Kyoto, Japan, Jan. 15, 2025 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced they have started offering samples of the industry’s smallest [1] terahertz (THz) wave ...

Researchers develop electronic circuit boards from modified mushroom material that enables complete component recycling and natural decomposition while matching conventional performance.
