Focused ion beam tuning of in-plane vibrating micromechanical resonators
Vibrating resonators are important components of micromechanical systems, with applications in sensors and actuators. However, defects and stresses can cause resonance shifts, and it is important to develop methods of tuning. Passive methods are based on dimensional trimming and active methods on electrically-induced stress. For example, reactive ion etching (RIE) has been used to apply global ...
متن کامل2-tier in-plane motion correction and out-of-plane motion filtering for contrast-enhanced ultrasound.
OBJECTIVES Contrast-enhanced ultrasound (CEUS) cines of focal liver lesions (FLLs) can be quantitatively analyzed to measure tumor perfusion on a pixel-by-pixel basis for diagnostic indication. However, CEUS cines acquired freehand and during free breathing cause nonuniform in-plane and out-of-plane motion from frame to frame. These motions create fluctuations in the time-intensity curves (TICs...
متن کاملIn-Plane and out of Plane Free Vibration of U-Shaped AFM Probes Based on the Nonlocal Elasticity
Atomic force microscope (AFM) has been developed at first for topography imaging; in addition, it is used for characterization of mechanical properties. Most researches have been primarily focused on rectangular single-beam probes to make vibration models simple. Recently, the U-shaped AFM probe is employed to determine sample elastic properties and has been developed to heat samples locally. I...
متن کاملAn electro-thermal silicon-polymer micro-gripper for simultaneous in- plane and out-of-plane motions
An electro-thermal micro-gripper for both in-plane clamping and out-of-plane motion is presented. The device consists of both in-plane and out-of-plane actuators. Each gripper arm performs a 7.4 μm in-plane and a 14 μm out-of-plane motion at 1.6 V and 2.5V actuation voltage, respectively. The maximum temperature and power consumption are 180 °C and 26.5 mW and 80 °C and 87.3mW for the in-plane ...
متن کاملUnconstrained Two-parallel-plane Model for Focused Plenoptic Cameras Calibration
The plenoptic camera can capture both angular and spatial information of the rays, enabling 3D reconstruction by single exposure. The geometry of the recovered scene structure is affected by the calibration of the plenoptic camera significantly. In this paper, we propose a novel unconstrained two-parallel-plane (TPP) model with 7 parameters to describe a 4D light field. By reconstructing scene ...
