Abstract: An intraocular pressure (IOP) includes a transmission film component, which is in direct contact with intraocular aqueous humor and configured to sense pressure fluctuations in the intraocular aqueous humor; a reflective film component set on an inner side of the transmission film component; and an adhesion layer component set on an inner layer of the reflective film component and configured to connect to an attachment device. An enclosed space formed by the reflective film component and the transmission film component constitutes a resonance chamber, which is filled with a filling medium. When a pressure in the intraocular aqueous humor is changed, the transmission film component is deformed, resulting in a change in a near-infrared (NIR) spectrum reflected by the reflective film component; the IOP is detected according to the change of the NIR spectrum.

Abstract: A wearable cardioverter defibrillator (“WCD”) system may include an impedance detector configured to render an impedance signal of the patient. The WCD system may determine, from the impedance signal, a characteristic of breathing by the patient that can be used as a vital sign. The WCD system may determine, from at least the breathing characteristic, whether or not a shock criterion is met. If the shock criterion is met, the WCD system may control a discharge circuit to discharge a stored electrical charge through the patient. An advantage can be that the breathing characteristic may be used to determine whether or not a patient is experiencing a condition that requires defibrillation therapy, such as sudden cardiac arrest. Even more advantages can be had in discerning the state of the patient when the breathing characteristic is combined with other data, such as from a motion detector.

Abstract: The invention provides a method (10) for detecting a neural respiratory drive measure of a user. The method includes obtaining (100) an EMG signal and processing (200, 280) the EMG signal to produce a surrogate respiration signal and a processed EMG signal. Inhalations of the user are then detected (300) based on the surrogate respiration signal. The detected inhalations are then used in conjunction with the processed EMG signal to determine (400) a neural respiratory drive measure of the user.

Abstract: A paralysis monitoring system can be utilized during various medical procedures. Generally, the system is used during procedures involving anesthesia, when general paralysis is necessary, e.g., during surgery that requires cutting through or mobilizing muscle tissue. The paralysis monitoring system stimulates a nerve with low voltage signals and can provide for continuous monitoring and recording of the evoked muscle activity throughout and after a procedure. By monitoring a quantitative response of the muscle activity to nerve stimulation, an anesthesiologist may adjust subsequent doses of a paralytic agent to achieve a desired level of paralysis.

Abstract: Aspects describe capturing the dynamic movement of one or more leaders and generating stimulus signals in real time for one or more followers to perform substantially the same movement. A model of each follower is optionally employed to transform the observed movement of a leader to a series of movement cues that will overcome any follower physical and cognitive limitations while maximizing the movement compliance and benefit from the directed movement. Also provided is the capability of establishing a library of therapeutic, fitness, rehabilitation or dance movement scripts that may be replayed at the follower's convenience without a leader present. Additionally, one aspect provides for continually monitoring follower movement to detect unstable movement, an increased likelihood of a fall and gait anomalies and initiating a stimulus pattern to reduce the chance of a fall or injury.

Abstract: Systems and methods for detecting deceptive intent of a subject include observing eye movements of the subject and correlating the observed movements to known baseline neurophysiological indicators of deception. A detection system may record eye movement data from the subject, compare the eye movement data to a data model comprising threshold eye movement data samples, and from the comparison make a determination whether or not the subject is lying. The detection system may create an alert if deception is detected. The eye movements detected include saccadic and intersaccadic parameters such as intersaccadic drift velocity. Measurements may be collected in situ with a field testing device, such as a non-invasive, non-contact device attached to the subject's computing device and configured to non-obtrusively record the eye movement data.
