摘要： Computer programs and computer-implemented methods implement techniques for displaying zero-width markers in an electronic document. An electronic document including content having a visual content is provided. The electronic document includes one or more markers having locations in the content, the markers not being represented in the content. Input specifying one or more locations in the electronic document is received. The presence of one or more markers associated with one or more locations in the specified locations is detected in response to the input. A visual representation of the detected markers is displayed. In preferred embodiments, the display of the visual representation does not alter the visual composition of the document.

摘要： Embodiments of the present invention feature a method and apparatus for detecting defects, such as, leaks, component failure and adverse performance. One embodiment of the present apparatus for pumping fluid comprises a pumping chamber having an inlet and an outlet powered by a motor. The motor operates in pumping mode upon receiving a pumping signal. The apparatus further comprises at least one inlet valve in fluid communication with the inlet of the pumping chamber. And, the apparatus comprises a switchable valve in fluid communication with the outlet of the pumping chamber. The switchable valve has a closed position and an open position, and assumes the closed position upon receiving a close signal. A pressure measuring device is in fluid communication with the pumping chamber, between said inlet valve and switchable valve. The pressure measuring device determines a minimal pressure and first threshold pressure at a first time and a second threshold pressure at a second time. The control means calculates the slope of a line representing the difference of said first threshold pressure signal and said second threshold pressure signal over time and comparing the slope with a threshold decay value. And, the control means compares the minimal pressure to a minimal acceptable value. Deviations from such values represent a defect in the pump.
