Standard North American installation of a combination hot box / dragging equipment detector A defect detector is a device used on railroads to detect axle and signal problems in passing trains . The detectors are normally integrated into the tracks and often include sensors to detect several different kinds of problems that could occur.
The microphone transducer converts sound pressure from a user's voice into an electric current, which is then converted back to sound by a transducer at the receiver nodes. The most significant distinction between ordinary telephones and sound-powered telephones is in the operation of the microphone.
A smart transducer is an analog or digital transducer, actuator, or sensor combined with a processing unit and a communication interface. [ 1 ] As sensors and actuators become more complex, they provide support for various modes of operation and interfacing.
An orthomode transducer (OMT) is a waveguide component that is commonly referred to as a polarisation duplexer. Orthomode is a contraction of orthogonal mode . Orthomode transducers serve either to combine or to separate two orthogonally polarized microwave signal paths. [ 1 ]

The SAI provides the termination of individual twisted pairs of a telephony local loop for onward connection back to the nearest telephone exchange (US: "central office" (CO)) or remote switch, or first to transmission equipment such as a subscriber loop carrier multiplexer and then to the exchange main distribution frame (MDF).
An Alabama woman "is recuperating well" after undergoing a pig kidney transplant in New York City, per reports. Towana Looney, 53, underwent surgery using the organ from a genetically manipulated ...
One or more metal pins, or probes, protrude into the waveguide at right angles to the axis and act as antennas, feeding the signal to a printed circuit board inside the LNB's shielded box for processing. The lower frequency IF output signal emerges from a socket on the box to which the coaxial cable connects.
