In today’s medicine, the celerity of bio-assays analysis is crucial for timely selection appropriate therapy and hence its effectiveness, especially in case diseases characterized by late onset symptoms. this paper, a lens-less fiber optics-based fluorescence sensor designed measurement labeled presented potential early diagnosis sepsis via C-reactive protein (CRP) detection demonstrated. The p...

Recording the variation of joint angles as a feedback to the control unit is frequent in articulated arms. In this paper, magnetic sensor AS5045, which is a contactless encoder, is employed to measure joint angles of 6R robot and the performance of that is examined. The sensor has a low volume, two digital outputs and provides a high resolution measurement for users; furthermore its zero positi...

Network sensors consist of sensor nodes in which every node covers a limited area. The most common use ofthese networks is in unreachable fields.Sink is a node that collects data from other nodes.One of the main challenges in these networks is the limitation of nodes battery (power supply). Therefore, the use oftopology control is required to decrease power consumption and increase network acce...

This paper describes our work on high quality rapid prototyping. The focus is on techniques that produce prototypes of desired quality and yet do not take long to build. We present necessary information about methods of control, power, sensors, batteries, electronics, and more. We outline materials, methods, and tools. We also explain how to use servomotors, Lego, and electronics to achieve sat...

carbon paste electrode was modified by disodium 2,4-diamino-7-methylbenzo[g] pteridine-5,10-dioxide to fabricate a sensor for potentiometric determination of vanadyl ion (vo2+) in aqueous medium. the new ligand was synthesized in three steps with high yield. the optimal composition of the carbon paste was made of graphite powder (64.5%), ionophore (16.6%), paraffin oil (17.8%), and sodium tetra...

Wafer-type PZT transducers are very effective as active sensors for Lamb wave studies in elastic plates and in steel bridge girders. It has been demonstrated that a single transducer can be used in pulse-echo mode, transmitting a transient waveform and then detecting return signals echoing from boundaries, irregularities, and flaws such as cracks. We describe here an inductively-coupled system ...

The implementation of a compact continuous-time optical transient sensor with commercial CMOS technology is presented. In its basic version, this sensor consists of a photodiode, five transistors and a capacitor. The proposed circuit produces several output signals in parallel. These include a sustained, logarithmically compressed measure of the incoming irradiance, half-wave rectified and thre...

Fluorescence is one of the most important analytical methods used in biological studies. In the past decade or two, instrumentation in this field has greatly advanced, and now it is possible to detect single photons or fluorescent molecules [1,2], or break the Abbe diffraction limit to distinguish two points spaced less than 50 nm apart [3]. Concurrently, the development of improved fluorescent...

In this paper, an approach to the automatic detection of vehicles at long range using sequences of thermal infrared images is presented. The vehicles in the sequences can be either moving or stationary. The sensor can also be mounted on a moving platform. The targetarea in the images is very small, typically less than 10 pixels on target. The proposed method consists of two independent parts. T...
