"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 ...
Wi-Fi Sensing (also referred to as WLAN Sensing [1]) is a technology that uses existing Wi-Fi signals for the purpose of detecting events or changes such as motion, gesture recognition, and biometric measurement (e.g. breathing).
A rotating line camera is a digital camera that uses a linear CCD array to assemble a digital image as the camera rotates. [1] The CCD array may consist of three sensor lines, one for each RGB color channel. Advanced rotating line cameras may have multiple linear CCD arrays on the focal plate and may capture multiple panoramic images during ...
Gyroscopes measure the angular rate of rotational movement about one or more axes. Gyroscopes can measure complex motion accurately in multiple dimensions, tracking the position and rotation of a moving object unlike accelerometers which can only detect the fact that an object has moved or is moving in a particular direction.
Rolling (optional Motion Mount upgrade adds mechanical shutter) [87] 1.22:1 sensor windowing and 2x/1.3x desqueeze [ 88 ] Combination optical low pass / IR (interchangeable with low-light optimized version), [ 89 ] optional Motion Mount upgrade adds ND 0.48 - 2.4 (up to 1.2 with mechanical shutter)
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
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 ...
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.
