Patent number: 7720306Abstract: Systems and methods of this invention display data using pixels with information indicated by color and intensity changes, particularly used for monitoring of physiological variables in real time. For certain methods, physiological data can be acquired by sensors, acquired data can be stored in data frames, data frames can be processed using computer-implemented methods, and processed data frames can be scaled to a display frame for display on a display device. Using such methods, a spot made up of a group of pixels can be updated during a time frame, or cycle using a computer-implemented method, such as addition, subtraction, multiplication, division or a time dependent function. Newly received data can be combined with prior received data to indicate time-dependent changes. In this way, each spot contains a cumulative history of data starting at some initial time. In other embodiments, visual contrast can be enhanced between desired data and other data.Type: GrantFiled: August 29, 2006Date of Patent: May 18, 2010Assignee: Photomed Technologies, Inc.Inventors: Allan Gardiner, Brent Michael McCullough
