Methods and systems for monitoring use, determining risk, and pricing insurance policies for a vehicle having autonomous or semi-autonomous operation features are provided. According to certain aspects, vehicle operation safety may be enhanced. An environmental or weather condition (e.g., hail, storm, wind) may be identified that presents a hazard to an autonomous or semi-autonomous vehicle. With the customer's permission, when it is determined that the vehicle is parked in an unprotected location, a protected or covered location to park the vehicle may be identified, a route to that location may be determined, and the vehicle may be directed to travel automatically to the protected location under the operation of autonomous operation features. Insurance discounts or cost savings may be provided to risk averse insurance customers based upon the self-parking functionality that will reduce or mitigate damage to insured vehicles caused by adverse conditions, falling trees or power lines, hail, etc.

The invention provides a method of medical imaging. The method comprises: receiving, for a current active time window (204A-N) and during a brain activity analysis session (200, 500), fMRI data of a region of interest (309) of a subject (318) in an active state. A transverse relaxation, T2*, map may be generated from the fMRI data using a predefined model of fMRI data variations. The generated T2* map may be compared with a reference T2* map. A blood-oxygen-level dependent (BOLD) response of the region of interest (309) during the current active time window (204 A-N) may be estimated using the results of the comparison.

Disclosed herein are systems and methods of generating traumatic brain injury. More specifically, the present disclosure relates to acoustic systems and methods for inflicting traumatic brain injury and developing an animal model of traumatic brain injury.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A method quantitatively determines fusion capacity in conjugate eye movements of a subject. Visual stimuli are provided for stereopsis as a task for the subject, the stimuli being generated at a viewing angle relative to the primary viewing direction of the subject such that the subject must execute a movement of the viewing direction of the eyes away from the primary viewing direction. Each stimulus is presented for a period of time so that the subject perceives the respective stimulus. The subject reacts to the respective stimulus perceived thereby within a reaction time. The reaction time is determined as the duration between presentation of the relevant stimulus and the subject's motor response to the stimulus. The steps are carried out continuously with stimuli for stereopsis at varying cognitive degrees of difficulty. A series of measurements of reaction times is generated at different cognitive degrees of difficulty.

An illustrative optical measurement system may include a wearable assembly comprising a plurality of modules each configured to fit within a different slot of the wearable assembly. The plurality of modules may include a module that comprises first and second light sources each configured to emit light directed at a target and a set of detectors configured to detect arrival times for photons of the light emitted by the first and second light sources. A ratio of a total number of the detectors to a total number of the light sources is at least two to one.

A head-mounted display device includes a display panel positioned to provide an image toward an eye of a wearer of the head-mounted display device; one or more light sources positioned to provide illumination light toward a head of the wearer; and one or more light detectors for receiving a portion of the illumination light that has been scattered by the head of the wearer so that one or more characteristics associated with a blood flow in the head of the wearer are determined based on the received portion of the illumination light. A method of determining one or more characteristics associated with a blood flow in a head of a wearer of the head-mounted display device is also described.

The present invention provides a removable optical imaging device cap for use with a near infrared (NIR) light optical imaging device for detecting intracranial hematoma.

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, the operating status and/or configuration of autonomous operation features of an autonomous or semi-autonomous vehicle may be determined, such as via an on-board computer system or mobile device, and/or then directly or indirectly wirelessly communicated via data transmission from the vehicle computer system or mobile device to a remote server. An adjustment to one or more risk levels associated with operation of the autonomous or semi-autonomous vehicle may also be determined, and an auto insurance policy, premium, or discount may be adjusted based upon the adjustment to the risk levels and presented to the customer for their review and approval. As a result, insurance cost savings may be passed onto risk averse customers that opt into to a rewards program.

Systems, apparatuses, methods, and non-transitory computer-readable media for mapping a section of a vasculature of a subject are described herein, including moving a probe to a first position at a body of the subject adjacent the section of the vasculature; transmitting, by the probe, a first ultrasound beam into a first portion of the section of the vasculature through the body of the subject; receiving first ultrasound data including at least one imaging parameter of the first portion based on the first ultrasound beam; moving the probe to a second position at the body of the subject adjacent the section of the vasculature and different from the first position; transmitting, by the probe, a second ultrasound beam into a second portion of the section of the vasculature through the body of the subject; receiving second ultrasound data including the at least one imaging parameter of the second portion based on the second ultrasound beam; and constructing a map of the section of the vasculature based on the first ultrasound data and the second ultrasound data.
