We describe an approach allowing high-resolution transmission electron microscopy (HRTEM) on specimens like graphene and the investigation on their electronic transport properties at the same time. The experimental set-up presented here is based on the modification of a commercial TEM specimen holder and on a specially designed sample carrier. A customized Hall sensor confirms that the local ma...

We investigated the performance of Hall sensors with different Co-C ratios, deposited directly in nanostructured form, using Co(2)(CO)(8) gas molecules, by focused-electron or ion-beam-induced deposition. Due to the enhanced intergrain scattering in these granular wires, the extraordinary Hall effect can be increased by two orders of magnitude with respect to pure Co, up to a magnetic field sen...

Magnetic angle sensors detect the angular position of a permanent magnet attached to a rotating shaft. The magnet is polarized diametrically to the rotation axis. No soft magnetic flux guides are present. The semiconductor die is placed on and orthogonal to the rotation axis. There are two kinds of systems: (i) perpendicular systems detect the field components perpendicular to the rotation axis...

We present an OUI that combines Hall Effect sensing and actuation through electromagnetically-manipulated ferrofluid. The movement of magnets worn on the fingertips, over a surface embedded with a Hall Effect sensor array and electromagnets, gives the user the ability to interact with ferrofluid. This system provides a three-dimensional, physically animated response, as well as three-dimensiona...

Sputter erosion of boron nitride (BN) is a critically important process in many Hall thrusters from the point of view of both lifetime assessment and contamination effects. This contribution describes the development of a laser based sensor for in situ monitoring of sputtered BN from Hall thrusters. We present a laser electro-optic system and its demonstrative measurement results from BN sputte...

This article advocates a new computing paradigm, called computing with time, that is capable of efficiently performing a certain class of computation, namely, searching in parallel for the closest value to the given parameter. It shares some features with the idea of computing with action potentials proposed by Hopfield, which originated in the field of artificial neuron networks. The basic ide...

This paper presents the design of digital controller for a BLDC motor to control the speed and position control using Digital Signal Processor (DSP) TMS320LF 2407 which is used in an Electromechanical Actuator. Brushless D.C motor (BLDC) are one of the motor types rapidly gaining popularity. This motor offer a simple and rugged motor Solution for many variable speed drive application. Rotation ...

Pre-launch absolute calibration coefficients for the CCD/CBERS-2B sensor have been calculated from radiometric measurements performed in a satellite integration and test hall in the Chinese Academy of Space Technology (CAST) headquarters, located in Beijing, China. An illuminated integrating sphere was positioned in the test hall facilities to allow the CCD/CBERS-2B imagery of the entire sphere...

In this paper, we are presenting a new type of pointing interface for computers which provides mouse functionalities with near surface haptic feedback. Further, it can be configured as a haptic display where users may feel the basic geometrical shapes in the GUI by moving the finger on top of the device surface. These functionalities are achieved by tracking three dimensional positions of the n...
