A physiological signal processing system for a physiological waveform that includes a cardiovascular signal component provides a variable high pass filter that is responsive to the physiological waveform, and that is configured to high pass filter the physiological waveform in response to a corner frequency that is applied. A heart rate metric extractor is responsive to the variable high pass filter and is configured to extract a heart rate metric from the physiological waveform that is high pass filtered. A corner frequency adjuster is responsive to the heart rate metric extractor and is configured to determine the corner frequency that is applied to the variable high pass filter, based on the heart rate metric that was extracted. Analogous methods may also be provided.

A heartbeat sensor obtains a heartbeat of a driver. A concentration level computing unit estimates a concentration level of the driver at a time later than a timing of obtaining the heartbeat by the heartbeat sensor, on the basis of the heartbeat obtained by the heartbeat sensor. A state determining unit controls driving assistance for a vehicle on the basis of a comparison of the concentration level of the driver estimated by the concentration level computing unit with a target concentration level of the driver that is set in association with a position or an environment in which the vehicle driven by the driver is predicted to travel.

An onboard system equipped to a vehicle includes a vehicle control device controlling a switching of a driving mode of the vehicle between a manual driving and a self-driving, and a brain activity sensor capable of detecting an activated portion of a brain of a driver of the vehicle. The vehicle control device determines whether a degree of uneasiness felt by the driver exceeds a threshold or not based on a detection result detected by the brain activity sensor before the switching of the driving mode. When determining that the degree of uneasiness felt by the driver does not exceed the threshold, the vehicle control device switches the driving mode. When determining that the degree of uneasiness felt by the driver exceeds the threshold, the vehicle control device performs a vehicle control corresponding to the degree of uneasiness felt by the driver.

A distributed control system includes a remote control system configured to be communicatively coupled with plural separate vehicle systems. The remote control system is configured to remotely control operation of the vehicle systems and/or communicate with the local vehicle control system or operator. The remote control system also is configured to one or more of change how many of the vehicle systems are concurrently controlled by the remote control system or change how many remote operators of the remote control system concurrently control the same vehicle system of the vehicle systems.

A device, a system, a method, and a program are realized which are capable of predicting the order of the feeling and the preference of a subject to products which are the research objects, for marketing research and others. The images of a plurality of research objects are presented a plurality of times as visual stimuli in order to measure the brain wave. A brain wave data of an event related electrical potential for the research objects which the subject has selected as a target immediately after the stimulus presentation, is processed by a linear discriminant analysis to quantitatively represent with a single index, in order to rank the research objects.

Described herein are tetherless, forehead-mounted temperature regulation apparatuses configured to enhance sleep.

A method and device for biomedical recording of biomedical spike signals is provided. The method includes extracting and aligning possible biomedical spike signals from received signals and, thereafter, performing spike detection by determining whether the possible biomedical spike signals are actual spike signals. The biomedical spike signals are preferably selected from electrocardiography (ECG), electroencephalography (EEG) and neural signals.

A method and system for treating schizophrenia and other forms of mental illness, including: given a brain comprising neurons coupled by an axon including an inner core and an outer myelin sheath, and given one or more defects in the outer myelin sheath, repairing the one or more defects in the outer myelin sheath with one or more of a protein and a lipid such that the outer myelin sheath has a substantially constant electrical impedance for the transmission of data energy between the neurons and such that data energy is not undesirably reflected from the direction of a receiving neuron in the direction of a transmitting neuron within the axon.

A patient advisory device (“PAD”) and its methods of use. The PAD may be configured to alert the patient about an estimated brain state of the patient. In preferred embodiments, the PAD is adapted to alert the patient of the patient's brain state, which corresponds to the patient's propensity of transitioning into an ictal brain state, e.g., having a seizure. Based on the specific type of alert, the patient will be made aware whether they are highly unlikely to have a seizure for a given period of time, an elevated propensity of having a seizure, a seizure is occurring or imminent, or the patient's brain state is unknown.

Certain embodiments may relate to presenting advertisements in a virtualized environment. A method and apparatus may be provided. The method may include generating, by a virtual reality device, a virtualized environment for a user. The method may also include inserting an advertisement within the virtualized environment. The method may further include determining that the user has viewed the inserted advertisement. The method may also include determining a response of the user when the user views the inserted advertisement. The method may further include storing the response of the user.
