An information processing apparatus includes: an estimator configured to estimate, based on biological information of a human subject, a sleep indicator indicative of a depth of sleep of the human subject; and a volume controller configured to control a volume adjuster that generates a second playback sound signal by adjusting an amplitude of a first playback sound signal, such that the first playback sound signal is adjusted based on the sleep indicator and a volume of an ambient sound in an environment in which the human subject is situated.

Aspects of the present invention provide an approach for dynamically optimizing a beat. In an embodiment, a current movement rate and biometric data for each user in a group performing a physical activity are collected. An upcoming movement rate for each user is predicted based on the collected current movement rates and biometric data. Music having an optimized beat is then generated based on a lowest upcoming movement rate among the predicted upcoming movement rates.

Systems and methods for sonifying electrical signals obtained from a living subject, particularly EEG signals, are disclosed. A time-domain signal representing the activity of an organ is obtained. A voltage of the time-domain signal over a time block is determined. An acoustic signal based on the time-domain signal over the time block is produced. The acoustic signal comprises one or more audibly discernible variations representative of the activity of the organ. If the determined voltage is over a threshold voltage, the time-domain signal is squelched over at least a portion of the time-block as the acoustic signal is produced. The time-domain signal can be squelched by ramping down the signal as an input to produce the acoustic signal. The frequency spectrum of the acoustic signal can also be adjusted as it is produced, such as by flattening the signal and/or attenuating high frequencies along the frequency spectrum of the signal.

The invention provides the supporting system for neurological state assessment and neurological rehabilitation, especially within cognitive and/or speech dysfunction, characterized in that, the processing unit (PU) is integrated with the screen (S), which is equipped with the touch input sensors (TIS), said camera and light sources work within infrared radiation, wherein the infrared camera (IFC) is integrated with at least two infrared light sources (ILS). The infrared light sources (ILS) and the infrared camera (IFC) are formed into a movable component (MC) in the way that the infrared light sources (ILS) are located symmetrically and uniaxially on both sides of the infrared camera (IFC) in the movable component (MC). The movable component (MC) is connected with the processing unit (PU) through the screen (S). In another aspect the invention provides the method for supporting of neurological state assessment and neurological rehabilitation, especially within cognitive and/or speech dysfunctions.

Eye prescriptions may be determined by providing a simple, easy to use, portable device with a specially configured targeting light source that aligns the eye, mitigates accommodation, and provides accurate results. Unlike stationary, closed view autorefractors, this device typically is portable, self-usable, relatively inexpensive, enabling more widespread use across the world.

A medical method performed by a medical device, includes: generating a ECG tracing using a first electrode placed on a surface of a patient and a second electrode at a catheter inside the patient; and outputting the ECG tracing for presentation to a user; wherein the first electrode is fixed in position with respect to the patient; and wherein an amplitude of the ECG tracing corresponds with a relative distance between the first electrode and the second electrode. A medical device includes: a first electrode configured for placement on a surface of a patient; a second electrode configured for coupling with a catheter; and a processing unit configured to generate a ECG tracing using the first electrode on the surface of the patient and the second electrode inside the patient.

A system for adjusting the firmness of a substrate configured to support a subject includes a first rod configured to be movable by a mechanism, a second rod parallel to and spaced from the first rod a distance that spans a majority of a dimension of the substrate, and flexible straps extending between the first rod and the second rod and attached to the first rod and the second rod at respective ends of each flexible strap. The mechanism is configured to move the first rod in a first direction to increase tension on the flexible straps and move the first rod in a second direction to decrease tension on the flexible straps. The mechanism can be manually operated by the subject or can be a motor that is controlled by a controller.

A biological information measurement device that performs sound wave communications with an external terminal including a microphone includes a housing; a measurement circuit that measures biological information; a modulation circuit that converts the biological information measured into a sound wave signal; and a vibration member that vibrates based on the sound wave signal transmitted from the modulation circuit. The measurement circuit, the modulation circuit and the vibration member are provided inside the housing. The housing includes a terminal placement surface on which the terminal is placed. The vibration member and the terminal placement surface are in contact with each other so that vibration of the vibration member is transmitted to the terminal placement surface.

The invention relates to a method and apparatus for providing feedback to a user, in particular relating to the fall risk of the user and/or relating to advice to reduce the fall risk of the user. According to an embodiment, there is provided an apparatus for providing feedback to a user, the apparatus comprising a user interface for providing feedback to the user; and a processing unit. The processing unit is configured to obtain measurements of the fall risk of the user over a time period, the time period comprising at least one time portion in which the fall risk of the user increases to a first threshold value while moving, the user rests for a resting period when the fall risk reaches the first threshold value, and the user subsequently resumes moving; analyse the measurements of the fall risk of the user to determine the duration of each resting period and the fall risk of the user at the end of each resting period when the user subsequently resumes moving; determine a fall risk recovery profile for the user from the duration of each resting period and the fall risk of the user at the end of each resting period; determine the duration of a resting period required for the fall risk of the user to decrease to a second threshold value using the fall risk recovery profile; and provide feedback to the user on the determined duration via the user interface.

The steps of the method are: providing a generator adapted to produce specific wavelengths to maximize light emissions; providing a scintillator in operative proximity to the generator, the scintillator having an associated scintillator screen of a specific phosphor or other excitive type sensitive to various wavelengths, the scintillator being sensitive to a wavelength that maximizes light emissions; positioning a patient to be diagnosed between the generator and the scintillator; emitting a specific wavelength from the generator to and through the patient onto the scintillator screen whereby the associated scintillator screen will light up and sparkle to produce a light image of the patient; providing a camera in operative proximity to the scintillator screen to record the light image produced on the scintillator screen; providing a computer with a computer screen and software; capturing and analyzing the recorded light images from the camera; and obtaining a diagnosis for treatment of the patient.
