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.

Opportunistic plethysmography using video cameras

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.

Wireless data security between vehicle components

A system and method include contactless detecting and tracking cardiac activity by making use of a feedback control system, such as a Phase Locked Loop (PLL), in real-time or from a prerecorded signal stream.

Method and system for contactless detection of cardiac activity

A system and method for using the skin of a vehicle as a waveguide for surface waves to support far-field signal propagation to provide communications between various electrical nodes on the vehicle and for providing power signals. A dielectric layer is formed on the skin to define the waveguide, and a coupler couples signals from the node to the waveguide and receives signals from the waveguide to be sent to the node.

Using a vehicle structure as a medium for communication and power distribution

The present invention is directed to a method for establishing a symmetric encryption key between a first device and a second device. The symmetric encryption key is a function of a phase difference of the signals emitted between the first device and the second device and distance between the first device and the second device.

Methods establishing a symmetric encryption key and devices thereof

What is disclosed is a system and method for recovering a patient's cardiac pulse rate from a sequence of video images recording of that patient. In one embodiment, a reference signal of a particular frequency is generated at predetermined frequency intervals and a constrained source separation is performed on the source data to obtain an estimation of the source signal intended to be recovered. The reference signal is updated and constrained source separation is again performed. These operations are repeated for all frequencies of the reference signal. The frequency at which a minimum error is achieved is determined to be the subject's recovered cardiac pulse frequency. In such a manner, the source signal is extracted and recovered reliably from captured multi-channel RGB signals or multispectral signals. The teachings hereof find their uses in a variety of medical solutions including various military, security and telemedicine applications. Various embodiments are disclosed.
