A pressure monitoring system has a first chamber and a second chamber separated by a diaphragm. The tournament includes a plurality of successive games. A motor provides the swinging movement of the ultrasonic array transducer underneath the front shell so as to scan a volume of the region of interest. The system additionally assigns effort levels to the set of routing rules, wherein a higher effort level for a routing rule indicates that a higher amount of resources are available to satisfy the routing rule. An image capturing component, at the second side of the second lens, has an image capture surface directed toward the second lens to capture images of the light reflected from a sample capture surface at the focal plane of the first lens. When the display panel rotates relative to the main board in a same plane, the third rotating board will not rotate, only the first and second rotating boards rotate relative to the base plate and provide an anchor and limitation function.
