A system for sensing physiological traits of a maternal patient and a fetal patient carried by the maternal patient during a pregnancy using one or more sensors. The system may use the physiological traits sensed to define a maternal attribute for the maternal patient and a fetal attribute for the fetal patient, such as a heart rate, blood pressure, respiration rate, temperature, oxygen saturation level, or other attributes. The system is configured to compare the maternal attribute to a maternal limit describing a threshold for the maternal patient and/or compare the fetal attribute to a fetal limit describing a threshold for the fetal patient. The system is configured to issue a communication to the maternal patient and/or a clinician based on the comparisons. In examples, the system regularly communicates the maternal attribute and/or the fetal attribute to an output device of the maternal patient and/or a clinician.

A method includes receiving a pressure signal from a pressure sensor and/or a flow signal from a flow sensor and receiving signals from one or more sensors that measure different physiological parameters from the pressure sensor and the flow sensor. The method includes detecting the onset of the spontaneous breath by the patient based on the pressure signal and/or the flow signal and synchronizing providing breathing support to the patient with the onset of the spontaneous breath detected utilizing the pressure signal and/or the flow signal. The method includes calibrating parameters and thresholds to be utilized in detecting the onset of the spontaneous breath based on the signals. The method includes after calibration, switching to: detecting the onset of the spontaneous breath by the patient based on the signals and synchronizing providing breathing support to the patient with the onset of the spontaneous breath detected utilizing the signals.

A cue processor uses one or more sensors to obtain motion data for a user performing a physical task in an environment. A cueing law is based on a model determined from the motion data, for example a movement and skill model where the collected motion data are parsed into one or more movement units used to accomplish a range of outcomes. The cue processor generates a movement phase estimation to predict a movement phase and associated movement feature, and applies the cueing law to generate a cue signal. The cue signal is communicated to the user as a visual, audio or haptic stimulus, selected to target the feature for the user to achieve or improve a desired outcome.

A system for aiding a subject development of physical, mental, and/or emotional skills, subject awareness of their mind state, body state, and/or emotional state, and providing subject biofeedback includes subject-internal signal sensing devices wearable by the subject for sensing signals generated internal to the subject's body; subject-external signal sensing devices for sensing signals generated external to the subject's body; a local computing unit configured for authenticated wireless communication with the subject-internal and subject-external signal sensing devices, and presenting particular types of mind state, body state, and emotional state information to the subject, for instance, in the form of biofeedback (e.g., mind-body state biofeedback, and/or mind-body-emotion state biofeedback); and a cellular network communication unit configured for communicating data corresponding to sensed subject-internal signals and sensed subject-external signals to at least one server by way of at least one cellular network.

The present invention generally relates to a system and method for fine motor control of fingers on a prosthetic hand. In particular, the present disclosure describes a system and method for controlling the flexion or extension of one or more fingers of a prosthetic hand to reproduce a natural stroke such as for, e.g., writing, painting, brushing teeth, or eating. The systems and methods described herein use electromyographic (EMG) signals and, more particularly, combinations of electromyographic signals, from muscles in the forearm to activate one or more motors of the prosthetic hand that control the motion of the prosthetic fingers. The electromyographic signals may be used to cause fingers of a prosthetic hand to, for example, imitate a writing stroke while the fingers of the prosthetic hand hold a writing utensil. Additionally, the present invention describes electrode placement locations that maximize peak signal detected while maintaining a low base-line signal.

A urodynamic investigation apparatus for receipt of urine from a bladder is provided. The apparatus is characterized by a tubular element, first and second fittings, and a sleeve element, for select passage of urine there through, within the tubular element. The tubular element is characterized by opposing first and second end portions, and a port. The fittings are adapted to be received by the opposing end portions of the tubular element so as to delimit an apparatus chamber. The sleeve element, suspended between the fittings within the chamber, has collapsed and open configurations. The collapsed configuration is indicative of a no urine flow condition, and the open configuration indicative of a urine flow condition, with the sleeve element urine flow condition being a function of pressure applied to the chamber via the port of the tubular element.

A physiological signal sensing system and a physiological signal sensing method are provided. The physiological signal sensing system includes a signal processing device and a physiological signal sensing device having a plurality of sensing electrodes. The sensing electrodes are used to contact the skin of an organism to sense a plurality of physiological signals. The signal processing device is coupled to the physiological signal sensing device to receive the physiological signals, compares these physiological signals with the reference physiological signal pattern to obtain a comparison result, selects a selected electrode pair from the sensing electrodes based on the comparison result, and uses the selected electrode pair to perform physiological signal measurement on the organism during a normal operation period.
