Being the working FBG ultrasonicPROBLEM TO BE SOLVED: To enhance accuracy for evaluating soundness of a structure, by improving ultrasonic wave detecting sensitivity, by detecting an ultrasonic wave in an optional place of a subject by a movable FBG (fiber Bragg grating) ultrasonic sensor.津田 浩...
tsunamis, swells, and other coastal processes. [vii] A tide gauge can use an ultrasonic sensor to detect real-time water level. The gauge is often linked to an online database where a record is maintained, and in case of a risky situation, the system can trigger an alarm. ...
Insignal conditioning unit, the output of the sensor may be amplified, filtered or modified to the desired output voltage. For example, if we consider a microphone it detects the audio signal and converts to the output voltage (is in terms of millivolts) which becomes hard to drive an out...

An ultrasonic flow meter consists of at least one sensor and transducer pair. Each member of the pair can act both as a transmitter and a receiver. When in transmit mode, an oscillating electrical current creates a vibration in the piezoelectric crystal, and an ultrasonic wave is sent through...
This article covers Security sensors basics and types of Security sensors including their applications.It describes working operation of different types of Security sensors viz. motion sensors,Ultrasonic sensor,Tomographic sensors,wireless sensors,chemic
(generally an electrical signal), and then uses the computer or circuit equipment to process the signal output by the sensor to achieve automatic control. Since the response time of the sensor is generally relatively short, industrial production can be controlled in real-time through the computer ...
Apple is working on new fingerprint sensing technology that could work through an iPhone display by taking advantage of off-axis angular light.
. The Trigger and the Echo pins are both I/O pins and hence they can be connected to I/O pins of the microcontroller. To start the measurement, the trigger pin has to be made high for 10uS and then turned off. This action will trigger an ultrasonic wave at frequency of 40Hz from ...
