The present invention is directed to a sensing modality for measurement of vital signs, particularly in neonates, using inkjet-printed sensors in order to create a low cost and computationally less-intensive monitor. The invention incorporates the use of sensors specifically design to measure abdominal flex as a measure of their respiration rate. Neonates in particular exhibit abdominal flex during respiration. The flex sensor can be coupled with other off-the-shelf sensors or sensors made using same principles, connected together to a phone through the AUX port of a cell phone or other device for data collection and processing. The sensor can also be configured to communicate wirelessly with a computing device, such as a smartphone.

The present invention is directed to the standardization of prestrain applied to a sensor of an external respiratory measurement device. The method may comprise sandwiching the sensor between two adhesive layers and stretching the sensor by a fixed amount in order to match the length of the device to the length of a support layer. The device may then be covered by the support layer in order to keep the sensor in a state of prestrain, such that the length of the device matches the length of the support layer. The device may then be applied to the surface by the lower adhesive layer, and the support layer may then be removed, thus leaving the sensor in a standardized and optimal state of prestrain.

A surgical instrument navigation system is provided that visually simulates a virtual volumetric scene of a body cavity of a patient from a point of view of a surgical instrument residing in the cavity of the patient. The surgical instrument navigation system includes: a surgical instrument; an imaging device which is operable to capture scan data representative of an internal region of interest within a given patient; a tracking subsystem that employs electro-magnetic sensing to capture in real-time position data indicative of the position of the surgical instrument; a data processor which is operable to render a volumetric, perspective image of the internal region of interest from a point of view of the surgical instrument; and a display which is operable to display the volumetric perspective image of the patient.

For generating a breathing alert is disclosed, a method receives a video stream of a subject. The method further estimates a breathing signal from the video stream. The method determines one of a large-scale motion and/or a breathing event of the subject based on the breathing signal. The method generates an alert if both no breathing event is identified and no large-scale motion of the subject is identified within an event time interval.

Hemodynamic performance of a heart may be improved by determining, from a location associated with a diaphragm, an occurrence of a valid cardiac event; and then delivering asymptomatic electrical stimulation therapy directly to the diaphragm at termination of a diaphragmatic stimulation delay period that is timed relative to the occurrence of the valid cardiac event. The diaphragmatic stimulation delay period may be automatically established by sensing a plurality of cardiac events directly from a diaphragm; and for each of the sensed cardia events, determining whether the sensed cardiac event represents a valid cardiac event or a non-valid cardiac event. The diaphragmatic stimulation delay period is then calculated based on a plurality of sensed cardia events that are determined to be valid.

A sleep apnea and obesity comorbidity treatment system includes a transceiver and a control module. The control module is configured to: receive sensor data, where the sensor data is indicative of a glucose level of a patient and a ketones level of the patient, transmit the sensor data to a remote feedback device, receive feedback information from the remote feedback device based on the sensor data, and where the feedback information provides indications to the patient to maintain or alter a behavior of the patient based on the glucose level and the ketones level, and based on the feedback information, performing an operation to maintain or alter at least one of a diet or physical activity of the patient.
