Data representing one or more characteristics of an input airflow (e.g., an airflow associated with a human being, such as breath or an airflow resulting from motion of the human being, or a wind tunnel airflow) is acquired and, if necessary or desirable, processed, then stored, transmitted to a remote location, and/or played back. Playback of acquired airflow data entails generating a display airflow corresponding to the input airflow. The characteristic of an airflow regarding which data is acquired is often the velocity of the airflow, though data regarding other airflow characteristics (e.g., direction, temperature, humidity, odor) can also be acquired in addition to, or instead of, airflow velocity.

A system for automatically measuring and recording when fluid such as urine is introduced to a fluid collection container is provided. The system includes a measuring device that includes a load cell in communication with other various electronic components. The load cell is attached on one end to a fixed object like a hospital bed. At its other end, it is attached to a fluid collection container such as a urine collection bag. When fluid is introduced into the container, the load cell detects a stress change. A strain gauge (or gauges) on the load cell detects a resistance change and reads the change as a voltage change. That voltage change is amplified and digitized and converted to a weight, volume, and flow rate, before being transmitted to a recordkeeping system like electronic medical records. The system thus provides for real time measurement of fluid output collected in the container.
