Intelligent Sensor
An intelligent sensor is a sensor that takes some predefined action when it senses the appropriate input (light, heat, sound, motion, touch, etc.). Description The sensor has to do the following tasks: *Give a digital signal. *Be able to communicate the signal. *Be able to execute logical functions and instructions. Elements of intelligent sensors * Primary sensing element * Excitation control * Amplification * Analogue filtering * Data conversion * Compensation * Digital information processing * Digital communication processing Technical capacities Because the tasks are performed by microprocessors, any gadget which mixes a sensor and a microprocessor is usually called an intelligent sensor. To qualify as an intelligent sensor, the sensor and processor must be part of the same physical unit. A sensor whose only function is to detect and send an unprocessed signal to an external system which performs some action is not considered intelligent. Ubiquitous Sensor Networks (USN ...

Microprocessor
A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit. The integrated circuit is capable of interpreting and executing program instructions and performing arithmetic operations. The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results (also in binary form) as output. Microprocessors contain both combinational logic and sequential digital logic, and operate on numbers and symbols represented in the binary number system. The integration of a whole CPU onto a single or a few integrated circuits using Very-Large-Scale Integration (VLSI) greatly reduced the c ...

Ubiquitous
Omnipresence or ubiquity is the property of being present anywhere and everywhere. The term omnipresence is most often used in a religious context as an attribute of a deity or supreme being, while the term ubiquity is generally used to describe something "existing or being everywhere at the same time, constantly encountered, widespread, common". Ubiquitous can also be used as a synonym for words like worldwide, universal, global, pervasive, all over the place. The omnipresence of a supreme being is conceived differently by different religious systems. In monotheistic beliefs like Christianity and Judaism, the divine and the universe are separate, but the divine is present everywhere. In pantheistic beliefs, the divine and the universe are identical. In panentheistic beliefs, the divine interpenetrates the universe, but extends beyond it in time and space. Introduction Hinduism, and other religions that derive from it, incorporate the theory of ''transcendent and immanent omn ...

Real-time Locating System
Real-time locating systems (RTLS), also known as real-time tracking systems, are used to automatically identify and track the location of objects or people in real time, usually within a building or other contained area. Wireless RTLS tags are attached to objects or worn by people, and in most RTLS, fixed reference points receive wireless signals from tags to determine their location. Examples of real-time locating systems include tracking automobiles through an assembly line, locating pallets of merchandise in a warehouse, or finding medical equipment in a hospital. The physical layer of RTLS technology is often radio frequency (RF) communication. Some systems use optical (usually infrared) or acoustic (usually ultrasound) technology with, or in place of, RF. RTLS tags and fixed reference points can be transmitters, receivers, or both, resulting in numerous possible technology combinations. RTLS are a form of local positioning system and do not usually refer to GPS or to m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smart Transducer
A smart transducer is an analog or digital transducer, actuator or sensor combined with a processing unit and a communication interface. As sensors and actuators become more complex they provide support for various modes of operation and interfacing. Some applications require additionally fault-tolerance and distributed computing. Such high-level functionality can be achieved by adding an embedded microcontroller to the classical sensor/actuator, which increases the ability to cope with complexity at a fair price. Typically, these on-board technologies in smart sensors are used for digital processing, either frequency-to-code or analog-to-digital conversations, interfacing functions and calculations. Interfacing functions include decision-making tools like self-adaption, self-diagnostics and self-identification functions, but also to control how long and when the sensor will be fully awake, to minimize power consumption and to decide when to dump and store data. They are often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Of Things
The Internet of things (IoT) describes physical objects (or groups of such objects) with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communications networks. Internet of things has been considered a misnomer because devices do not need to be connected to the public internet, they only need to be connected to a network and be individually addressable. The field has evolved due to the convergence of multiple technologies, including ubiquitous computing, commodity sensors, increasingly powerful embedded systems, as well as machine learning.Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F.,Fault-tolerant cooperative navigation of networked UAV swarms for forest fire monitoring Aerospace Science and Technology, 2022.
