  • Patent number: 9734722
    Abstract: An application engine receives flight position data associated with an airplane through a global computing network. The flight position data includes a list of recorded locations of the airplane. Using the list of recorded locations of the airplane, the application engine computes a current position of the airplane and a polling interval. Responsive to calculating the current position of the airplane, the application engine generates a flight status view of the airplane based on the current position of the airplane. The flight status view includes a flight tracker image representative of the airplane's current location and flight path, and one or more visual indicators corresponding to social network data and informative data associated with the current position of the airplane. The application engine periodically updates the flight status view of the airplane using an updated current position of the airplane.

  • Patent number: 4515396
    Abstract: To analyze a human patient's heart activity over an extended period of time a portable EKG monitor is attached to the patient through electrodes and the patient maintains a diary of his activities and subjective feelings over a monitoring period. The recorded data is then used to form a graphic record consisting of a plurality of trace segments each representative of short consecutive intervals in the overall monitoring period. These records are necessarily to a very reduced scale and to allow the physician to obtain more detailed information regarding anomolous periods the graphic record is observed and various interesting segments are recorded on a substantially amplified scale. The first macroscopic and the second microscopic display segment are arranged in book form with the enlarged microscopic display segments on opposed pages from the macroscopic display segments to allow their simultaneous review and evaluation.
