Causes and Symptoms of Upper Abdomen Pain. 1  Abdominal Aortic Aneurysm - This condition materializes due to a weak area in the aorta wall. Over time, the wall may rupture due to its weakened condition. As the aorta is the largest artery in the body, this can be a serious condition.
Principles of Motion Sensing. Sensors able to detect three-dimensional motion have been commercially available for several decades and have been used in automobiles, aircraft and ships. However, initial size, power consumption and price had prevented their mass adoption in consumer electronics. While there are other kinds of motion detector technologies available commercially, there are four principle types of motion sensors which are important for motion processing in the consumer electronics market.
Their use is recommended for detecting moving objects outdoors or in thoroughfares indoors. The scope of installing or suggesting Motion Detectors is greater as compared with a True Presence or an Occupancy Sensor. The Costs of a Motion Sensor is lower as compared to the Presence sensor due to the technology and sensitivity involved. High-resolution and sensitive: Presence detectors respond to the tiniest movements using extremely high resolution, precision sensor technology.
