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.
The TPS sensor is a potentiometer type of electrical component. Rather than just being opened or closed like a switch, the TPS controls the circuit by varying its resistance in response to throttle position. In most cases this sensor will send a very low voltage back to the vehicle's main computer when the throttle plates are fully closed. This reference voltage rises as the throttle opens to increase speed. Keep in mind that some manufacturers use inverse voltage readings for feedback.
