A mechanical mouse jiggler for an Apple mouse. A mouse jiggler is a software used to simulate the movement of a computer mouse. [1] [2] It can also be a mechanical device moving the physical computer mouse. In all cases, it prevents sleep mode, standby mode or the screensaver from activating. Mouse jigglers are also known as mouse movers. [3]
We all experience periods of better and worse sleep because, well…life. But if you regularly have trouble sleeping, improving your sleep hygiene can help. 7 Ways to Improve Your "Sleep Hygiene ...
[4] [13] The motion sensors in smartphones and smartwatches are not medical-grade, smartphone data alone is not enough to capture the full picture of a patient's sleep staging, and data collected from consumer sleep-tracking devices are not reliable enough as monitoring tools as they tended to over or under-estimate data such as total sleep time.
Sensitivity to sound improves as the signal duration increases up to about 200 to 300 ms, after that the threshold remains constant. [2] The timpani of the ear operates more as a sound pressure sensor. Also a microphone works the same way and is not sensitive to sound intensity.
Sensory deprivation or perceptual isolation [1] is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and the ability to know which way is down.
Research showed that both sleep and wake are not equally assessed by actigraphy devices. When compared, data collected through polysomnographs and actigraphs defines sensitivity; which is the proportion of sleep correctly detected by both methods. Actigraphy reveals itself to be more likely to detect sleep than wake phases. [12]
On 25 August 2009, U.S. patent 7,580,533 was issued for a device that uses a laser beam and smoke or vapor to detect sound vibrations in free air ("Particulate Flow Detection Microphone based on a laser-photocell pair with a moving stream of smoke or vapor in the laser beam's path"). Sound pressure waves cause disturbances in the smoke that in ...
