In this paper, a 120 frames per second (fps) low noise CMOS Image Sensor (CIS) based on a Two-Step Single Slope ADC (TS SS ADC) and column self-calibration technique is proposed. The TS SS ADC is suitable for high speed video systems because its conversion speed is much faster (by more than 10 times) than that of the Single Slope ADC (SS ADC). However, there exist some mismatching errors betwee...

range (six decades), the power consumption will be 71 mW. Normal operation produces events at a maximum of 4MHz, for a dynamic range of five decades, while consuming 10mW. A full VGA with three decades of dynamic range operates at 2.46MHz and consumes only 1.3mW. Fig. 4 shows how the output rate per pixel, dynamic range, power and array size scales. The main drawback to this approach is the com...

Computer mining rigs are specially designed for only one purpose which is to mine crypto assets efficiently and effectively. Mining takes a lot of time, therefore it very important pay attentionto computers mining. The better the quality PC or computer, faster processwill be. So far, consumers in choosing rig computer observe computerwithout looking at special criteria such as price, motherboar...

In order to improve the position control accuracy of industrial robots and solve problems poor real-time reconfigurability traditional motion controllers, a hardware implementation method for mechanism system multi-functional is proposed. The video acquisition suitable infrared detectors containing 4 channels or readout circuits in channels. display compatible with old AV/S-Video interface, als...

The solution of Systems of Simultaneous Non-Linear Equations (SNLE) remains a complex and as yet not closed problem. Although analytical methods to tackle such problems do exist, they are limited in scope and, in general, demand certain prior knowledge of the functions under study. In this paper we propose a novel method to numerically solve such systems by using a Genetic Algorithm (GA). In or...

OBJECTIVES To evaluate visual grading characteristics (VGC) and ordinal regression analysis during head CT optimisation as a potential alternative to visual grading assessment (VGA), traditionally employed to score anatomical visualisation. METHODS Patient images (n = 66) were obtained using current and optimised imaging protocols from two CT suites: a 16-slice scanner at the national Maltese...

BACKGROUND Coronary computed tomography angiography (CCTA) requires high spatial and temporal resolution, increased low contrast resolution for the assessment of coronary artery stenosis, plaque detection, and/or non-coronary pathology. Therefore, new reconstruction algorithms, particularly iterative reconstruction (IR) techniques, have been developed in an attempt to improve image quality with...

Defect related states and excitonic transitions in epitaxial GaN have been studied by combining cathodoluminescence and transmission electron microscopy. A series of deep levels with energies at about 2.4, 2.6 and 2.8 eV has been found by low temperature cathodoluminescence on freestanding 150 mm thick epitaxial GaN. These deep levels are characterised by a high recombination efficiency. They a...

FPGA implementation projects will use a Terasic DE2i-150 development board, as shown below. The DE2i-150 features an Intel Atom N2600 processor and an Altera Cyclone IV GX FPGA, along with a variety of standard I/O peripherals (USB, Ethernet, VGA, etc.). The DE2i-150 ships with Yocto Linux pre-installed. My recommendation is to stick with Yocto, rather than installing a more mainstream distribu...
