A device for measuring fluid pressure in the lumen of a syringe including a pressure transducer integrally mounted in the plunger of the syringe under the plunger tip, such that the force applied by the plunger to the fluid in the syringe is transmitted to the transducer and the resulting electronic signal is converted to a display value for aiding a physician. In accordance with an embodiment, such a system includes an enterprise crawl and search framework which abstracts an underlying search engine, provides a common set of application programming interfaces for developing search functionalities, and allows the framework to serve as an integration layer between one or more enterprise search engine and one or more enterprise application. A loss-composing point-calculating section 18d calculates loss-composing points constituting a loss outline formed on the measurement object based on the reference points and the reference curve. If a window property is set to size to the content, a window size is computed during layout, having a height andor width based on the child elements plus X and Y deltas for a window non-client area and borders. In particular, it has application to conversion of pulse code modulated signals, such as used in CDs and DVDs, to a pulse width modulated or analog signal.
