The invention relates to a method for detecting and classifying a motor seizure. The method comprises receiving video data of a patient; detecting a first anomaly in the video data as anomaly in movement of the patient; determining a video frame stack comprising the first anomaly; classifying the video frame stack using a pre-trained neural network to obtain a first classification; and determining a motor seizure type based on the first classification.

Methods and systems for monitoring use, determining risk, and pricing insurance policies for a vehicle having one or more autonomous or semi-autonomous operation features are provided. According to certain aspects, a computer-implemented method for responding to damage to an autonomous or semi-autonomous vehicle relating to a collision or other loss may be provided. With the customer's permission, an indication of damage to the autonomous or semi-autonomous vehicle, and/or operating data regarding operation of the vehicle during (i) a time period without the damage to the autonomous or semi-autonomous vehicle, and (ii) a time period with the damage to the autonomous or semi-autonomous vehicle may be received. Repairs associated with the damage may be determined based upon the operating data, as well as an expected cost associated with the repairs. Insurance discounts may be provided to risk averse customers that timely repair damaged vehicles or features that impact vehicle safety.

In one embodiment, a personal flotation device that can be worn by a user includes an inflation system including an inflatable bladder, a gas-generating component configured to generate gas using a chemical reaction and inject the generated gas into the bladder to inflate it, and an actuator configured to activate the gas-generating component; a sensor configured to sense one or more physiological parameters of the user; and an inflation control system configured to receive physiological parameter data from the sensor, to determine whether or not the user is experiencing a medical event that places the user at risk of drowning, and, if the user is experiencing such a medical event, to signal the actuator to activate the gas-generating component so as to provide floatation to the user.

Systems, methods and apparatuses described herein generally provide a millimetre size package-free complementary metal-oxide-semiconductor (“CMOS”) chip (referred to as a “die”) for the in situ (on-site) measurement or imaging of electrochemically detectable analytes.

A method and an apparatus for analyzing heart rate Variability (HRV), and use thereof are provided. A low-cost, portable and wearable signal acquisition device is utilized to acquire electrocardiography (ECG) signals of epilepsy patients for 24 hours before treatment, and a time domain index, a frequency domain index and a nonlinear index of the ECG during a long term and during a short term are calculated with a programmed HRV analysis method, and the efficacy of vagus nerve stimulation (VNS) treatment for patients with medically intractable epilepsy is accurately and efficiently predicted based on characteristic parameters for characterizing an effect level of the vagus nerve regulating the heart rate, i.e., vagus nerve activity, thereby avoiding unnecessary costs and avoiding the delay of the optimal treatment timing. In addition, the characteristic parameters obtained by the HRV analysis on the ECG may be utilized to clearly select VNS treatment indication patients.

A method of monitoring a patient for seizure activity may include monitoring the patient by collecting an electromyography signal, determining features of the signal using wavelet analysis and inputting determined feature values into a neural network trained to detect seizure activity. Related apparatuses are also described.

An electrode device is disclosed that is removably implantable at least partially in a bone or other tissue. The electrode device includes a head and a shaft connected to the head. The shaft has a shaft body extending distally from the head in an axial direction of the shaft, and a conductive element including a conductive surface at a distal end of the shaft. A plurality of discrete anchor elements can project from an outer surface of the shaft body in a transverse direction of the shaft. A conductive wire can be permanently fixed to a proximal end surface of the conductive element, the end surface being located in or adjacent the head. The head can have a convex outer surface and a concave inner surface. An electrode array and a reamer tool is also disclosed.

A method for assessment, optimization and logging of the effects of a therapy for a medical condition, including (a) receiving into a signal processor input signals indicative of the subject's brain activity; (b) characterizing the spatio-temporal behavior of the brain activity using the signals; (c) delivering a therapy to a target tissue of the subject; (d) characterizing the spatio-temporal effect of the therapy on the brain activity; (e) in response to the characterizing, optimizing at least one parameter of the therapy if the brain activity has not been satisfactorily modified and/or has been adversely modified by the therapy; (f) characterizing the spatio-temporal effect of the at least one optimized parameter; and (g) logging to memory the at least one optimized parameter. A computer readable program storage unit encoded with instructions that, when executed by a computer, performs the method.

In some aspects, a device wearable by a person includes a sensor configured to detect a signal from the brain of the person and a transducer configured to apply to the brain an ultrasound signal. The ultrasound signal has a low power density and is substantially non-destructive with respect to tissue when applied to the brain.

In some aspects, a device includes a sensor configured to detect a signal from the brain of the person and a plurality of transducers, each configured to apply to the brain an acoustic signal. One of the plurality of transducers is selected using a statistical model trained on data from prior signals detected from the brain.
