A sensor system with such a sensor patch is also disclosed.

A method for quantifying the balance of an individual includes segmenting, as a function of time, a statokinesigram(s) of an individual so as to generate several statokinesigram portions; extracting, from the statokinesigram portions, values of at least one trajectory parameter; determining the value of at least two quantifiers, from the values of trajectory parameters extracted in the extraction step, for each of the statokinesigram portions generated in the segmentation step; and determining said value representative of the balance of the individual from the values of the quantifiers of each of the statokinesigram portions. The method may be implemented by a processor and memory.

An action management apparatus includes a bodily information measurement unit that measures bodily information, a communication unit for performing near-field wireless communication with another apparatus having a function of measuring bodily information, a bodily information acquisition unit that acquires the bodily information measured by the other apparatus included in a group along with the action management apparatus via a communication unit, and an information output unit that, based on first bodily information measured by the bodily information measurement unit and second bodily information acquired by the bodily information acquisition unit, outputs management information for managing an action of a wearer of an apparatus belonging to the group.

Methods and systems are provided for obtaining cleaned sequences showing trajectories of movement of a center of gravity and for estimating a biometric information pattern or value of a target. One of the methods includes removing noises from initial sequences showing trajectories of movement of a center of gravity to obtain the cleaned sequences. Another one of the methods includes reading cleaned sequences of the target into a memory, extracting features from the cleaned sequences, and estimating a biometric information pattern or value of the target from the extracted features, using a classification or regression model of biometric information patterns or values. The biometric information pattern may be a pattern derived from respiratory or circulatory organs of a target.

A sleeve worn on an arm allows detection of gestures by an array of sensors. Electromyography, inertial, and magnetic field sensors provide data that is processed to categorize gestures and translate the gestures into commands for robotic systems. Machine learning allows training of gestures to increase accuracy of detection for different users.

A leg stabilization or performance system for a skier or snowboarder that absorbs part of the pressure on a user's legs and drives the resistance force down to user's boots, acting like a shock absorber is disclosed. This function also allows the skis or snowboard to keep closer contact with the snow, giving the skier/snowboarder more control through the turns. The performance system includes removably fixable leg straps, upper and lower adjustable leg shafts or portions, a resistance assembly with a shock absorber and a variable resistance adjuster, a boot attachment, and an activator switch. The configuration of the system allows a user to set the system to various levels of resistance.

The invention relates, to the field of motion tracking and sensorimotor assessment and training, by providing a method, system and software for tracking of a target by moving the head and neck or other body part in two or three-dimensional space. In particular the invention teaches a method to create incremental difficult classes of unpredictable movement patterns according to specific criteria. The created movement patterns can be used to accurately grade the deficits of movement control and other sensorimotor deficits of the head/neck and consequently a treatment can be prescribed which starts at each patient's impairment level by using the same method. The invention provides also a reliable and valid method to detect fraudulent neck compensation claims from genuine deficits by said assessment of sensorimotor function.

A method for mapping the trajectory of a part of the anatomy of a human or animal body. The method comprises receiving first sensor signals from a sensor attached to part of the anatomy of the human or animal body. The first sensor signals comprise three dimensional position information indicating the location of the sensor; determining from the first sensor signals at least two angles of rotation of the part of the anatomy to which the sensor is attached with respect to a centre of rotation of another part of the body, wherein the angles of rotation are selected from pitch, yaw and roll. Transforming the signals to provide two dimensional coordinate data defined in a two dimensional coordinate space wherein a first dimension in the two dimensional coordinate space represents a first angle of rotation of the part of the anatomy and a second dimension in the two dimensional coordinate space represents a second angle of rotation of the part of the anatomy; and stores the two dimensional coordinate data.

To provide a concentration measurement method that makes it possible to accurately, quickly, and non-destructively measure the concentration of a predetermined chemical component to a trace level of concentration by a simple means, that makes it possible to accurately and quickly measure the concentration of a chemical component within an object to be measured to a nano-order trace concentration level in real time, and that has a versatility which makes it possible to adapt said concentration measurement method to a variety of situations and embodiments. A time sharing method is used to irradiate an object to be measured with each of light of a first wavelength and light of a second wavelength having different light absorption rates with respect to the object to be measured, light of each of said wavelengths that arrives optically through the object to be measured as a result of irradiating with the light of each of said wavelengths is received by a shared light reception sensor, a signal relating to light of the first wavelength and a signal relating to light of the second wavelength are output from the light reception sensor in accordance with the received light and a differential signal of said signals is formed, and the concentration of a chemical component in the object to be measured is derived on the basis of the differential signal.
