  2. Mechanical amplifier - Wikipedia

    en.wikipedia.org/wiki/Mechanical_amplifier

    "A mechanical amplifier is basically a mechanical resonator that resonates at the operating frequency and magnifies the amplitude of the vibration of the transducer at anti-node location." [ 6 ] Resonance is the physical phenomenon where the amplitude of oscillation (output) exhibit a buildup over time when the frequency of the external forcing ...

  3. Time delay and integration - Wikipedia

    en.wikipedia.org/wiki/Time_Delay_and_Integration

    A time delay and integration or time delay integration (TDI) is a forward motion compensation (FMC) technique for capturing images of moving objects at low light levels. It's a type of line scanning where multiple linear arrays are placed side by side. After the first array is exposed, the charge is transferred to the neighboring line.

  4. Straight-line mechanism - Wikipedia

    en.wikipedia.org/wiki/Straight-line_mechanism

    The Scott Russell linkage (1803) translates linear motion through a right angle, but is not a straight line mechanism in itself. The Grasshopper beam/Evans linkage , an approximate straight line linkage, and the Bricard linkage, an exact straight line linkage, share similarities with the Scott Russell linkage and the Trammel of Archimedes .

  5. Motion detector - Wikipedia

    en.wikipedia.org/wiki/Motion_detector

    A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.

  6. Indoor positioning system - Wikipedia

    en.wikipedia.org/wiki/Indoor_positioning_system

    A large variety of techniques and devices are used to provide indoor positioning ranging from reconfigured devices already deployed such as smartphones, WiFi and Bluetooth antennas, digital cameras, and clocks; to purpose built installations with relays and beacons strategically placed throughout a defined space. Lights, radio waves, magnetic ...

  7. Linear amplifier - Wikipedia

    en.wikipedia.org/wiki/Linear_amplifier

    A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio-frequency (RF) power amplifier , some of which have output power measured in kilowatts , and are used in amateur radio .
