Question of the Week
Should Congress pass the Right to Repair Act?

This week's Question of the Week, a suggestion from INSIDER reader Glenn Barkley, concerns the Right to Repair Act, a bill that would require auto manufacturers to sell to non-dealer repair shops the complete repair information and diagnostic tools, currently only provided to dealer service centers....

Using Multiprocessing in Industrial Automation Systems

Automated industrial control systems are an integral part of today’s manufacturing facilities. As these systems’ capabilities advance, the engineer shifts from someone who oversees processes to one who manages the data produced and functions performed by these systems to ensure product...

Using FPGAs for Automated Design Validation

In the design process, after the first prototype returns from fabrication, engineers often use traditional test equipment to make low-level measurements such as digital rise times, voltage thresholds, and leakage currents, and analog harmonic and spurious distortion, noise, and more. Once these...

Implementing Rack-Level I/O Consolidation

The desire to consolidate datacenter I/O has existed for several decades. It has been driven by I/O hardware providers who didn’t want to develop multiple versions of the same I/O card for different computer busses, and by end-users who did not want to stock multiple cards, as well as manage different...

Nanostructuring Technology Creates Efficient, Ultra-Small Displays

University of Michigan scientists have created pixels that will enable LED-projected and -wearable displays to be more energy efficient with more light manipulation possible - all on a display that may eventually be as small as a postage stamp.

Portable Handheld Optical Window Inspection Device

The Portable Handheld Optical Window Inspection Device (PHOWID) is a measurement system for imaging small defects (scratches, pits, micrometeor impacts, and the like) in the field. Designed primarily for window inspection, PHOWID attaches to a smooth surface with suction cups, and raster scans a...

Predicting Long-Range Traversability From Short-Range Stereo-Derived Geometry

Based only on its appearance in imagery, this program uses close-range 3D terrain analysis to produce training data sufficient to estimate the traversability of terrain beyond 3D sensing range. This approach is called learning from stereo (LFS). In effect, the software...

Salience Assignment for Multiple-Instance Data and Its Application to Crop Yield Prediction

An algorithm was developed to generate crop yield predictions from orbital remote sensing observations, by analyzing thousands of pixels per county and the associated historical crop yield data for those counties. The algorithm determines which pixels...

Miniature Low-Noise G-Band I-Q Receiver

Weather forecasting, hurricane tracking, and atmospheric science applications depend on humidity sounding of atmosphere. Current instruments provide these measurements from ground-based, airborne, and low Earth orbit (LEO) satellites by measuring radiometric temperature on the flanks of the 183-GHz water...

Differential Resonant Ring YIG Tuned Oscillator

A differential SiGe oscillator circuit uses a resonant ring-oscillator topology in order to electronically tune the oscillator over multi-octave bandwidths. The oscillator’s tuning is extremely linear, because the oscillator’s frequency depends on the magnetic tuning of a YIG sphere, whose...

Optimal Flow Control Design

In support of the Blended-Wing-Body aircraft concept, a new flow control hybrid vane/jet design has been developed for use in a boundary-layer-ingesting (BLI) offset inlet in transonic flows. This inlet flow control is designed to minimize the engine fan-face distortion levels and the first five Fourier harmonic half...
