Abstract: An electronic billboard comprises at least one processor, at least one computer-readable tangible storage device, and program instructions stored on the at least one storage device for execution by the at least one processor. The program instructions comprise first program instructions configured to receive media content comprising text and at least one image. The program instructions further comprise second program instructions configured to separate the text and the at least one image. The program instructions further comprise third program instructions configured to cause the electronic billboard to display the text on a first predetermined portion of the electronic billboard. The program instructions further comprise fourth program instructions configured to cause the electronic billboard to display the image on a second predetermined portion of the electronic billboard.

Abstract: A spirometer for measuring fluid flow, particularly associated with exhalation of respiratory patients. The spirometer of this invention preferably has a fluidic oscillator wherein the fluid oscillates within a chamber of the fluidic oscillator. An oscillation frequency of the fluid flow within the chamber is correlated to a flow rate. A computer is used to process input data, such as data representing frequency of the oscillatory flow within the chamber, to a flow rate passing through the spirometer. The spirometer of this invention may have no moving parts, which results in the need for only a design calibration and no periodic calibrations throughout use of the spirometer.
