We live in a World of Sensors. Copyright law hampers the process of accessing information and availability of information, particularly for educational and library purposes. If the material is under copyright, copyright clearance and payment of copyright fees are necessary before the material can be reproduced or downloaded for teaching purposes. Some universities are generating content in the form of podcasts and via e-learning tools such as Moodle which is accessible using a mobile phone. The clearance process is slow and rights holders are often unwilling to grant permission if they know the material will be loaded onto a digital platform. This even includes CDs and DVDS. The prison system to which they were subject goes back to the late 1960s. It was the successor and the complement to the prison system on which blacks in South Africa are weaned with their mothers’ milk. In 1969 one of the editors of this journal met two South Africans in London who said they had fought in the first MK guerrilla operation in mid-1967 – a disastrous fiasco across the Zambezi River into the Wankie area of Rhodesia, along with guerrillas from the Zimbabwe African People’s Union (ZAPU), then led by James Chikerema. (The ZAPU president, Joshua Nkomo, was in detention). The two men described how they had eventually succeeded in escaping from Rhodesia, and how their criticism of the operation had led to their imprisonment in an ANC camp in Tanzania. An article on the theme appeared the same year in the British radical newspaper Black Dwarfthen edited by Tariq Ali. Detects body heat (infrared energy). Passive infrared sensors are the most widely used motion in home security systems. When your system is armed, your motion sensors are activated. Once the sensor warms up, it can detect heat and movement in the surrounding areas, creating a protective grid.” If a moving object blocks too many grid zones and the infrared energy levels change rapidly, the sensors are tripped. It is the property of metal that enables it to be deformed into thin sheet by rolling or hammering without the material being ruptured. Malleability is dependent on the crystal structure of the material. The higher the grain sizes of the metal the higher the malleability. Again, the smaller the grain sizes of any metallic material the lesser the malleability. How are grain sizes of metals obtained? With electron microscopic view of metals that have undergone metallography, the grain sizes can be obtained. This property is very important in engineering applications of metals.

Military standards or military specifications have been created for everything from the materials used by military contractors to the test procedures to the design requirements. Military standards, also called military specifications or mil spec, even reach down to the smallest details of product testing and acceptance criteria. Electronic media have several attributes in common. Radio, television, film (which has become electronic), and multimedia all present a diversity of program material appealing to a diversity of audiences. They can provide wide dissemination of information and culture to huge audiences through a variety of delivery systems and technologies. Some delivery systems are direct, immediate, and fleeting, such as broadcast, cable, cell phone services, and online systems or websites, such as Hulu. Our organization is dedicated to inspiring young people by engaging them in STEM (Science, Technology, Engineering and Mathematics) via robotics competitions, outreach activities, workshops and experiments. Passive IR sensor: When sensor does not use any IR source to detect the emitted energy from the obstacles it acts as a Passive IR sensor. Examples like thermocouple, pyro electric detector and bolometers comes under passive sensors. Gas composition sensor, humidity sensors, temperature sensors, position sensors, torque sensors, image sensors, rain sensors, fogging prevention sensors, distance sensors. We are fragmented in a dual way. That is, we are trying to manage and cotrol the present day gizmos and their techniques utilizing past or analogic technoligc. Analogic technology has be made obsolete by the emerging digital media and their constantly changing gizmos and their embedded techniques. In trying to amoeliorate this chasm, we are really doing a very shody job, and in effect, our present digtal media are the ones that are mediating this environment, and we have now become dependent on thse technologies and their techniques to mediate the reality created and enhanced for us by our own created media and their technologies. ASHRAE 90.1, Chapters 6, 8, and 9, were developed to drastically reduce overall building energy usage by imposing strict controls to HVAC, lighting, and power. Light sensors are an extremely broad sensor classification that covers a huge number of applications. One of the simplest applications of a light sensor is to detect ambient light levels. For example, outdoor lights that turn on automatically at dusk use a light sensor. With the perfect use of that stick electrode, many welding processes at that time became finer. Projection welding and seam welding were also greatly influenced by the involvement of stick electrode in the welding process. Many welding processes were benefited through this breakthrough in welding. The quality of gas welding and cutting began to improve rapidly. Blowtorch and low pressure acetylene were already there.

Digital and particularly, mobile technology, provides huge potential for research, learning and teaching purposes. A convergence of historical circumstance and an increase in innovative mobile applications may make Africa the first post-PC continent, because the majority of Africans do not have the luxury of laptops, iPads, Kindles and the like (Wanjiku, 2011). They will embrace mobile applications, like cell phones to engage the digital world. The mobile phone will become the main or default mode of information on the move for millions on the continent. Cell phones will be the means whereby Africans engage in communication, teaching and learning, civic, political and social activities, e-banking and other financial services. IR Sensors or Infrared Sensor are light based sensor that are used in various applications like Proximity and Object Detection. IR Sensors are used as proximity sensors in almost all mobile phones. What an interesting government South Africa has in power! Turbulent some might argue,but so very much corrupt as well. This is what we the poor have to deal this does not end there. These arise mainly from the fact that the data has historically never been intended for the study of climate, but rather for operational weather forecasting. Thus, for instance, when ships stopped measuring sea surface temps by throwing a bucket overside and measuring the temperature of the water they hauled up, this had the effect of a) improving measurements, and b) introducing a bias in the record. Similarly for site changes of weather stations, urbanization around stations, the introduction of Stevenson screens, and changes in observation times, and so on. We are developing, manufacturing and supplying work piece handling machinery for B2B customers of the mechanical engineering industry but also a variety of other industries all over the world. We thrive to create ergonomic and efficient solutions for and together with our customers. We look at the situation of every customer separately and based on our in-house knowledge and engineering are able to create custom-made solutions. If you have heavy work pieces to turn stop throwing out money and time as well as risking the health of your colleagues – make your production more ergonomic and efficient! Get in touch today, we are happy to help. If light bulbs are rated using lumens, why do light sensors have to use a different unit? It’s the reason musicians aren’t blinded at concerts. A single flashlight might seem blinding when shined an inch away from Drake’s eyes, but a sea of phone flashlights pointed at the stage isn’t bright at all. Because the light scatters as it leaves the phone, only a small amount of light hits his eyes on stage. As an object moves away from a light source, the share of the light that it receives also decreases. To properly measure the luminous flux as perceived by a surface, called illuminance, we use a unit called lux, which is equal to one lumen per square meter. At the same distance from a light source, a 1 square meter sheet is subjected to the same illuminance as a 10 square meter sheet. The larger sheet collects ten times as much light, if measuring luminous flux in lumens, but its area is just as large, so the illuminance is the same. If the sheets move toward the light source, the solid angle occupied by each the sheet increases, and therefore the illuminance also increases. The intensity of the light is constant, and the area of the sheets is constant, but the solid angle occupied increases, therefore increasing the illuminance they receive. Light sensors have to measure illuminance because it represents the light cast on a unit area, and because they cannot know what solid angle they occupy.
