Abstract: A method for capturing a high-quality cardiac plethysmography signal automatically and seamlessly using the video cameras embedded in personal electronic devices, includes a program running in the background that periodically takes a picture of the person using the device, runs face detection and/or recognition algorithm, and upon detection of a face, records a video, and then processes the video using algorithms to assess video quality by extracting video quality parameters. When video quality parameters are above predefined thresholds, the recorded video is processed further to generate a plethysmography signal indicative of cardiac activity. The plethysmography signal may then be processed to deduce cardiac activity. The method maintains a pleasurable user experience with the personal electronic devices.

Abstract: A mobile vehicle communications system and a method of determining the legitimacy of a wireless sensor signal received by an electronic control unit (ECU) in a vehicle. The method includes the steps of: receiving at the electronic control unit (ECU) a first wireless signal identified as being from a first vehicle sensor; performing a correlation procedure at the ECU using the first wireless signal; and based on the correlation procedure, determining whether the first wireless signal is a legitimate signal sent by the first vehicle sensor.
