The present invention provides a group monitoring device for monitoring a plurality of individuals engaged in an athletic activity, the device including a display configured to display, during an athletic activity: a metric relating to each of a plurality of individuals engaged in the athletic activity, and a status of a system component used to monitor the athletic activity. The group monitoring device may also include an input configured to allow manipulation of the display.

Device configured to non-invasively perform tissue monitoring. The device can include at least two light emitting components and at least one photodiode configured to receive reflected light generated from the at least two light emitting components. The at least one photodiode is spaced apart from the at least two light emitting components. The device can include an analog-to-digital converter component configured to generate a digitized detected light signal based on data received from the at least one photodiode. The device can further include a processor configured to execute instructions to process the digitized signals. The device can included an ambient light blocking component configured to surround the at least two light emitting components and the at least one photodiode to prevent external light from entering a region bounded by the ambient light blocking component. The device can also include at least one filter mounted over the at least one photodiode.

Systems and methods track a first object when continuous tracking information for the first object is not available. The systems and methods detect when the tracking information for the first object is not available. A last time of a last determined location of the first object is determined and a second object closest to the last determined location at the last time is determined. The location of the first object is associated with a location of the second object if tracking information for the first object is not available.

A computer-implemented method is described. The computer-implemented method is used for populating data of a graphical user interface (GUI). The computer-implemented method includes generating one or more graphical elements of one or more activities captured by a monitoring device. The monitoring device is usable by a user during the capturing. The method further includes generating a timeline including a time period over which the activities are performed. The timeline includes a chronological order of time within the time period. The method further includes generating an activity symbol for one or more of the activities performed during the time period. The activity symbol has an image that is graphically overlaid on the graphical elements of the activities.

Embodiments disclosed include a system and method for development of core muscles' support, comprising a means for identifying a user qualifying movement, a means for detecting a core muscle contraction in the identified qualifying movement, a means for discriminating between a core muscle contraction and no core muscle contraction in the identified qualifying movement; and a means to provide feedback to the user.

A method, system, and computer program for non-invasively monitoring a physiological parameter and providing biofeedback. The method, system, and computer program provide for the non-invasive detection of a physiological parameter by detecting changes in color channel values of a user in a live video feed and presenting biofeedback to the user indicating the relative position of the physiological parameter to an optimal range.

Hat, helmet, and other headgear apparatus includes dry electrophysiological electrodes and, optionally, other physiological and/or environmental sensors to measure signals such as ECG from the head of a subject. Methods of use of such apparatus to provide fitness, health, or other measured or derived, estimated, or predicted metrics are also disclosed.

A device for measuring an angular difference in a range of motion of the arms of a patient comprises a gripping bar, a housing, and an angle-determining assembly comprising a weighted needle and a compass. When the patient raises her arms to their unassisted physiological limits, the device indicates an angle that represents the angular difference in the range of motion between the arms of the patient.

A communicative water bottle includes communication logic and wireless transmission logic technology electronically connected with a variety of sensors either on the water bottle or located remote from the water bottle. The sensors on the bottle create digital data associated with amount of fluid in the bottle and change thereof. The sensors remote from the bottle, which can be on an activity tracker, create digital data associated with an activity being performed by a user, such as running, or the absence of activity, such as remaining sedentary. A display on the bottle can indicate to the user the amount of fluid consumed or a reminder that fluid should be consumed. The fluid consumption data syncs with other remote devices such as mobile applications executable on smartphones.

A foot sole pressure measurement instrument includes a measurement unit which is installed on a foot sole part of a subject and measures a pressure applied to the foot sole part of the subject, and an output unit configured to output data of the measured pressure.
