We demonstrate a means of creating a digital image by using a two-axis tilt micromirror to scan a scene. For each different orientation we extract a single gray scale value from the mirror and combine them to form a single composite image. This allows one to choose the distribution of the samples, and so in principle a variable resolution image could be created. We demonstrate this ability to c...

We present a mathematical theory of the two-dimensional offset curves from the viewpoint of medial axis transform. We explore the local geometry of the offset curve in relation with the medial axis transform, culminating in the classification of points on the offset curve. We then study the domain decomposition from the viewpoint of offsets, and in particular introduce the concept of monotonic ...

introduction : comorbidity is a new term in psychiatric nosology which despite its expansive use is not clearly defined. overlapping of axis i and axis ii disorders in multiaxial system of dsm and controversy over which disorders belong to which axis, have also complicated the issue. a number of studies investigating patterns of comorbidity for axis i and axis ii disorders could not find a one ...

In this paper, we perform the experimental characterization of two-axis MEMS scanners driven by radial vertical combdrive actuators. The dc scan ranges are limited by the pull-in effect. Each scanner utilizes a cross-bar spring structure to achieve two rotational degrees of freedom (DOFs) without employing any gimbal. Both the actuators and torsion springs are hidden underneath the mirror to ob...

In piezoresisitive two-axis accelerometers with two proof masses suspended by cantilever beams, there are generally many ways to configure the Wheatstone bridges. The configurations are different both with respect to functionality and performance. The main distinction is between bridges that contain resistors belonging to both proof masses, and the one bridge that doesn’t. We compare the differ...

This paper attempts to develop a machining error diagnosis method for classifying the sources on external/internal contour surfaces which are fabricated using two-axis cylindrical grinding machine. A derivation of profile wheel motion trajectory and also equations has been performed. Due contours having sinusoidal polynomial polar curve instead rose curve, equation is then used generate NC code...
