advert date January 2012 The Lace Sensor is a guitar pickup designed by Don Lace and manufactured by AGI Actodyne General International since 1985. This line of electric guitar pickups was used exclusively by Fender Musical Instruments Corporation Fender from 1987 to 1996. Lace Sensors are true single coil pickups however, internally they are different from classic single coils. The chief difference is that the coil is surrounded by metal barriers which are designed to reduce electro magnetic interference such as power line hum. According to the manufacturer, these barriers also help concentrate the magnetic field, allowing weaker magnets to be used, which results in less string pull. Less string pull, in turn, means truer pitch and intonation, and superior sustain . Ratings Four types of Lace Sensor pickups for Stratocaster were originally manufactured denoted with an following the model name , followed by five newer models, each with a different output rating and tone. Lace Sensors are also available for Telecaster, Precision Bass, Jazz Bass and Jazz Bass V. Dually A Lace Sensor Dually is effectively a double coil unit combining two Lace Sensor single coil pickups in a humbucker configuration. Both coils of the pickup are wired individually and left that way, so that the user may choose whether to wire them up as a humbucker, or one of several other ways.

A holographic sensor is a device that comprises a hologram embedded in a smart material that detects certain molecules or metabolites . This detection is usually a chemical interaction that is transduced as a change in one of the properties of the holographic reflection as in the Bragg reflector , either refractive index or spacing between the holographic fringes. ref DOI 10.1021 la102693m ref The specificity of the sensor can be controlled by adding molecules in the polymer film that selectively interacts with the molecules of interest. A holographic sensor aims to integrate the sensor component, the transducer and the display in one device for fast reading of molecular concentrations based in colorful reflections or wavelengths. Certain molecules that mimic biomolecule active sites or binding sites can be incorporated into the polymer that forms the holographic film in order to make the holographic sensors selective and or sensitive to certain medical important molecules like glucose, etc. The holographic sensors can be read from a fair distance quantify date November 2010 because the transducer element is light that has been refracted and reflected by the holographic grating embedded in the sensor.

Flip flop electronics Flip flop br 5. Output An inductive sensor is an electronics electronic proximity sensor , which detects metallic objects without touching them. The sensor consists of an induction loop . Electric current generates a magnetic field , which collapses generating a current that falls asymptotically toward zero from its initial level when the input electricity ceases. The inductance of the loop changes according to the material inside it and since metals are much more effective inductors than other materials the presence of metal increases the current flowing through the loop. This change can be detected by sensing circuitry, which can signal to some other device whenever metal is detected. Common applications of inductive sensors include metal detector s, traffic light s, car wash es, and a host of automated industrial processes. Because the sensor does not require physical contact it is particularly useful for applications where access presents challenges or where dirt is prevalent.

refimprove date September 2008 A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an Electromagnetic field electromagnetic field or a beam of electromagnetic radiation infrared , for instance , and looks for changes in the electric field field or return signal. The object being sensed is often referred to as the proximity sensor s target. Different proximity sensor targets demand different sensors. For example, a capacitive proximity sensor capacitive or photoelectric sensor might be suitable for a plastic target an inductive sensor inductive proximity sensor always requires a metal target. The maximum distance that this sensor can detect is defined nominal range . Some sensors have adjustments of the nominal range or means to report a graduated detection distance. Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between sensor and the sensed object. Proximity sensors are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing. This is common in large steam turbine s, compressor s, and motors that use sleeve type bearing s.

A photoelectric sensor , or photoeye, is a device used to detect the distance, absence, or presence of an object by using a light transmitter, often infrared , and a photoelectric effect photoelectric receiver. They are used extensively in industrial manufacturing. There are three different functional types opposed a.k.a. through beam , retroreflective, and proximity sensing a.k.a. diffused . Types A self contained photoelectric sensor contains the optics , along with the electronics . It requires only a power source. The sensor performs its own modulation , demodulation, Amplifier amplification , and output switching. Some self contained sensors provide such options as built in control timers or counters. Because of technological progress, self contained photoelectric sensors have become increasingly smaller. Remote photoelectric sensors used for remote sensing contain only the optical components of a sensor. The circuitry for power input, amplification, and output switching are located elsewhere, typically in a control panel. This allows the sensor, itself, to be very small. Also, the controls for the sensor are more accessible, since they may be bigger. When space is restricted or the environment too hostile even for remote sensors, fiber optics may be used. Fiber optics are passive mechanical sensing components. They may be used with either remote or self contained sensors. They have ... signal. The detecting range of a photoelectric sensor is its field of view , or the maximum distance the sensor can retrieve information from, minus the minimum distance.
