This paper presents a scalable column-row-parallel ASIC architecture for 3-D portable medical ultrasound. Through its programmable row-by-row or column-by-column operations both transmit and receive beam-formation, linear scaling in interconnection, data acquisition complexity, power dissipation, programming time is achieved. In addition, per-element controllers can activate fine granularity aperture definition when more functionality favored over the linear-scaling speed efficiency....
This paper presents a preview servo-loop speed control algorithm to achieve smooth, accurate, and computationally inexpensive tracking for connected automated vehicles (CAVs). Differing from methods neglecting the future road slope target information, proposed controller focuses on taking advantages of this accessible information better performance. It integrates into an augmented optimal problem, by solving which we obtain law in analytical form. The brake/throttle laws consist five parts,...
Point-of-care ultrasound (POCUS) is transforming healthcare worldwide as a diagnostic tool with the potential to significantly reduce delay between symptom onset and initiation of therapy. Conventional POCUS systems are based on piezoelectric transducers cable-connected electronics, which require costly manufacturing process usually come an undesirably limited channel count. Such devices typically serve specific subset clinical applications, imaging at different body parts calls for...
To accelerate self-driving technology developments, testing platforms modified from production passenger cars are widely used nowadays, but the powertrain models and control access to engine/motor often not available, e.g., popular hybrid Lincoln MKZ platform only opens brake/throttle pedal protocol for longitudinal motion. These limitations motivate us model dynamics by experiments design new speed controls, differing conventional cruise that manipulates engine/brake torque directly with...
