Abstract: A mechanical diagnostic probe is used to determine the thickness of articular cartilage, so that any degeneration in the articular cartilage can be detected at an early stage. The probe advantageously allows for calibrating the speed of the ultrasound in situ thereby allowing for more accurate measurements of the tissue thickness. The probe also can be used to monitor the condition of the cartilage after surgery and/or after or during physical rehabilitation of the cartilage. The probe is comprised of a probe handle and a probe, which is comprised of an ultrasonic transducer, strain-gauges, and a linear displacement actuator. A predetermined displacement then is applied to the indenter tip and a computer program is then used to analyze the results.

Abstract: The activity information accounting system stores an account title table corresponding to activity information, and performs accounting procedures on the basis of an input activity information and an account title corresponding to the input activity information. The accounting system displays activity types including purchase and acquisition activity, sales and revenue activity, expenditure activity, investment and finance activity, and production activity. If user selects one of the displayed activity types, the accounting system displays a screen for the user to input activity information for the selected activity type.
