How to use sensor in a sentence. However, these types of sensors are still not available for practical use. A smoke alarm is an essential sensor in case of fire. 'Nip it in the butt' or 'Nip it in the bud'? As for sensor technologies, biosensors utilizing the CWA target enzymes have been developed over the years (Guerrieri et al., 2002; Zayats et al., 2003; Walker and Asher, 2005). These types of sensors are still not practical to use. Definition noun, plural: sense organs An organ or structure that has nerve endings capable of detecting and reacting to a stimulus Supplement Sense organs pertain to the various organs or structures that consist of specialized nerve endings. Some biological sensors are applied to the body surface (for example, thermocouples for measuring skin temperature, electrodes in electroencephalography and electrocardiography, and sensors attached to an animal to record its movements in an experimental chamber or open-air cage). J.L. Which of the following is a fruit named after a Moroccan seaport. This implies the use of very small, wireless on-body sensors and of spatial sensors not requiring any light or dress limitation; the sensor system in a ME must be designed to support multi-sensor fusion, to assure that all the needed input can be gathered, to be integrated for as complex as necessary gesture and movement “style” analysis. The sensor can also detect how much VPHP has been absorbed by packaging and other materials within the facility, such as sterile isolators or other protective barriers.

The working conditions for many ME applications (e.g., a discotheque or a theatre stage) require a robustness and independency from light variations which is very difficult to obtain with video cameras. Hyperspectral sensor systems represent a revolutionary development increasing passive sensor spectral resolution to as high as a few nanometres. A single electronic charge resulting from the detection of one photon could result in as many as 50 charges at the output node. Two recent developments in CCD sensor technology are useful to light microscopists. Typically such sensors have a lower spatial resolution, and use lower sampling rates (~ 20Hz). The data processing methodology and strategy are, therefore, different from that employed for broadband images in many aspects. A cheap car alarm may be nothing but a shock sensor, in which a strong vibration will cause two metal surfaces to come together. Subscribe to America's largest dictionary and get thousands more definitions and advanced search—ad free! The advantage of chemiluminescent transduction includes very low optical background. Even though sensor technology and programming varies between manufacturers, the two main parameters that are commonly programmed are threshold and slope (Fig. A device that responds to a physical stimulus and converts the stimulus into a signal conveyed to another device. See more. What Is The Difference Between “It’s” And “Its”? In both of these devices, amplification of the signal substantially reduces the dynamic range because the charge storage wells are filled at a rate that is directly related to the amplification factor. A device for sensing and measuring light, pressure, or temperature, and sending information back to a computer. Japanese Whisky Is on the Rise, Exclusive: ISIS’s Enemies Ask Pentagon for Drones, Brain Bleed: Why Michael Schumacher’s Helmet Wasn’t Enough, Mio Alpha Review: A Strapless Continuous Heart Rate Monitor for Your Wrist. Ultrasound and optical (infrared, video cameras) technologies are typically used. On-body sensors are useful for tracking relative motion of parts of the body (e.g., distance between hands), and fine motion detection of trajectories, angles, velocity, acceleration. Test Your Knowledge - and learn some interesting things along the way. The following article is from The Great Soviet Encyclopedia (1979). Implanted sensor systems in both applications face daunting environmental challenges. These example sentences are selected automatically from various online news sources to reflect current usage of the word 'sensor.' Did You Know? “Affect” vs. “Effect”: Use The Correct Word Every Time. Conventional CCD cameras incorporate subsequent amplification stages that allow multiplication of the output of the readout amplifier. Send us feedback. Sanders et al.
