A Portable Scaler

A case of Caplan's syndrome in a boiler-scaler.

A Novel Portable Scissors-Type Fruit Picking Device

At present, the fruit picking in most countries still largely relies on manual operation. Manual fruit picking can protect the fruits from damage during the operation process. However, it is time-consuming and labor-intensive, and poses a potential safety risk to the workers while working at heights not reachable. Therefore, a variety of fruit picking machines and platforms have been developed ...

Entropy-Constrained Successively Refinable Scaler Quantization

We study the design of entropy{constrained successively reenable scalar quantizers. We propose two algorithms to minimize the average distortion and design such a quantizer. We consider two sets of constraints on the entropy: (i) constraint on the average rate and (ii) constraint on aggregate rates. Both algorithms can be easily extended to design vector quantizers.

Ultrasonic scaler oscillations and tooth-surface defects.

Damage to tooth root surfaces may occur during ultrasonic cleaning with both piezoelectric and magnetostrictive ultrasonic scalers. It is unclear which mechanism causes more damage or how their mechanism of action leads to such damage. Our null hypothesis is that tooth-surface defect dimensions, resulting from instrumentation with ultrasonic scalers, are independent of whether the scaler probe ...

A Very Low Power, Highly Integrated Multichannel Scaler

Multichannel Scaler (MCS) electronics are often used in lidar-based photon counting applications. The NASA SBIR Phase-I effort resulted in a highly integrated, low power, USB-based MCS hardware prototype and Windows-based software. The Phase-II project focused on expanding the Phase-I MCS development in creating a complete flexible lidar data acquisition “system-on-a-card." Key motivations in t...
