    en.wikipedia.org/wiki/Timex_Expedition_WS4

    The digital time is also displayed through an LCD watch with analogue hands located on the upper left corner of the dashboard. Timex Expedition WS4 in barometric chart mode. The trend of the barometric chart is negative, indicating decreasing atmospheric pressure, thus the cloud icon, just above the temperature display, indicates deteriorating ...

  3. Barograph - Wikipedia

    en.wikipedia.org/wiki/Barograph

    In the case of the graph on the barograph, one of two codes could be picked. An 8 (steady then decreasing) or 6 (decreasing then steady). The observer should pick the 6 because it represents the last part of the trace and is thus most representative of the pressure change. In the bottom centre is the aneroid (large circular silver object).

    en.wikipedia.org/wiki/Video_tracking

    Video tracking is the process of locating a moving object (or multiple objects) over time using a camera. It has a variety of uses, some of which are: human-computer interaction, security and surveillance, video communication and compression, augmented reality, traffic control, medical imaging [1] and video editing.

    The 17th century saw the development of the barometer and the Galileo thermometer while the 18th century saw the development of the thermometer with the Fahrenheit and Celsius scales. The 20th century developed new remote sensing tools, such as weather radars, weather satellites and wind profilers, which provide better sampling both regionally ...

  6. Pressure altimeter - Wikipedia

    en.wikipedia.org/wiki/Pressure_altimeter

    In aircraft, an aneroid altimeter or aneroid barometer measures the atmospheric pressure from a static port outside the aircraft. Air pressure decreases with an increase of altitude—approximately 100 hectopascals per 800 meters or one inch of mercury per 1000 feet or 1 hectopascals per 30 feet near sea level .

  7. Altimeter - Wikipedia

    en.wikipedia.org/wiki/Altimeter

    When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is a type of altimeter called a pressure altimeter or barometric altimeter. A pressure altimeter is the altimeter found in most aircraft , and skydivers use wrist-mounted versions for similar purposes.

    In 1844 he invented the barograph, that is, a device to monitor pressure, a recording aneroid barometer. [1] Passionate about his work, Vidi spent all his wealth to fund his research on the barograph. The invention proved successful, and Vidi managed to make profit of it, despite several legal battles.

    en.wikipedia.org/wiki/Barometric_light

    Barometric light was first observed in 1675 by the French astronomer Jean Picard: [4] "Towards the year 1676, Monsieur Picard was transporting his barometer from the Observatory to Port Saint Michel during the night, [when] he noticed a light in a part of the tube where the mercury was moving; this phenomenon having surprised him, he immediately reported it to the sçavans, ...
