Camera-Integrable Wide-Bandwidth Antenna for Capsule Endoscope.

This paper presents a new antenna design for a capsule endoscope. The proposed antenna comprises a camera hole and meandered line. These features enable the antenna to be integrated on the same side as the camera, within the capsule endoscope.

Effect of Radio Frequency Plasma Treatment on Evaporation Behavior and Characteristics of RuCr Alloy Powder.

The evaporation behavior and characteristics of jet milled RuCr alloy powders processed by radio-frequency (RF) plasma treatment were evaluated during this study. RF plasma treatment was found to be effective in eliminating internal pores and in manufacturing spherical powder. However, the RF plasma treatment resulted in the evaporation of Cr.
