Abstract: 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.

Abstract: A wearable strain sensor for measuring respiration volume and respiration rate is described herein. The wearable strain sensor includes a flexible yet not stretchable connector that connects soft electronics to hard electronics. The flexible and non-stretch able connector removes stress/strain from the soft/hard interface, thereby preventing damage to sensor components and maintaining electrical connection.

Abstract: The present invention is directed to the combination of respiratory data from two or more different sensors in order to generate a combined waveform. The system of the present invention may comprise a set of two strain sensors, each strain sensor comprising a bare sensor and an adhesive layer to apply said sensors to the skin of a patient, one on the chest and one on the abdomen. The system may further comprise a computing device connected to both strain sensors in some form. As the distention of the patient's skin puts strain on the strain sensors, waveforms are transmitted from the sensors to the computing device where both waveforms are combined into a singular waveform.

Abstract: The present invention is directed to the measurement of a baseline respiratory level in a patient so that changes in respiratory activity can be easily reported. The baseline measurement is collected by a sensor in the patient's chest and a sensor on the patient's abdomen, and is transmitted to a computing device. The computing device measures normal breathing for 60 seconds and uses the waveform collected over this period of time to generate a baseline RR, tidal volume, and minute ventilation. From this point, the patient's RR, tidal volume, and minute ventilation are recorded and compared to the baseline measurements, and if a change from the baseline measurement that exceeds a predetermined threshold is detected, the doctor is alerted that action must be taken for the patient's safety.

Abstract: Electronic displays devices can present electronically changeable displayed images including graphical and textual elements, for example, human and machine-readable elements. The devices can include a low-power-consumption display that uses little or no power until a portion of the display is changed. The electronic display devices can be wirelessly connected to computing devices such as portable computing devices (e.g., smartphones, smartwatches, tablets, laptops, etc.) and fixed gateway devices (e.g., wireless access points) by a wireless communications network. The devices can include a motion sensor and functionality for determining identity, proximity, and/or location of the device.

Abstract: Embodiments of a patient status sensor can be applied to a patient or trauma victim to provide a quick visual and/or audible indication of the patient's vital signs (e.g., respiration, heart rate, or other vital signs). Certain embodiments are configured as an adhesive patch that includes electrodes for measuring heart rate (and respiration in some implementations), a processor configured to perform calculations for determining one or more vital signs using information from the electrodes, and audible or visual indicators to communicate information about vital signs or patient status to a medical attendant. Certain embodiments include an access opening for providing intraosseous delivery of fluids to bone marrow (e.g., through sternal or long bone) and can be integrated or used with an intraosseous delivery system. Certain embodiments include wired or wireless components to communicate vital signs or patient status to an external monitoring device.

Abstract: Signal data obtained from a piezoelectric sensor placed on a patient's body is used to detect the presence of a cardiac pulse. The piezoelectric sensor has a transducing element adapted to sense movement due to a cardiac pulse and produce piezoelectric signal data in response thereto. Processing circuitry analyzes the piezoelectric signal data for a feature indicative of a cardiac pulse and determines whether a cardiac pulse is present in the patient based on the feature. In one aspect, the feature may be a temporal feature such as a relative change in energy. In another aspect, the feature may be a spectral feature such as the energy or frequency of a peak in the energy spectrum of the signal. In yet another aspect, the feature may be obtained by comparing the piezoelectric signal data with a previously-identified pattern known to predict the presence of a cardiac pulse. Multiple features may also be obtained from the piezoelectric signal data and classified to determine the presence of a cardiac pulse.

Abstract: Methods and systems for waking an individual to an alert condition such as smoke or a fire have greatly improved ability to wake sleeping individuals compared to conventional methods. For example, preferred waking devices include a fluid spray directed toward the head of a bed and the person sleeping in that bed. Used in conjunction with standard digital processing techniques, the systems offer greatly improved reliability and the ability to save lives.
