A computer-implemented system and method for coordinating payment for healthcare services are provided. The optical system includes, in order from an object, a first lens group G1 having positive refractive power, and a second lens group G2 having positive refractive power. The outlet pressure of the high-pressure-gas supply equipment is set to \u201c1critical pressure ratio\u201d or more times a filter inlet gas pressure so that the flow speed of the high-pressure gas ejected from the backwash nozzle is the speed of sound or higher. Each finite state machine receives an input select signal to control which clock source should be active and passed to a clock output. Capture pulses are then generated by selected distributed clock dividers to capture test data coming form the circuit blocks into the scan chains. The water contact area of said ceramic support element is separated from the electronic circuit E by a seal in the housing H.
