A variable-color region (106) of an information-presentation structure extends to an exposed surface (102) at a surface zone (112) and normally appears along it as a principal color. An impact-dependent portion (138) of the variable-color region responds to an object (104) impacting the zone at an object-contact area (116) by providing an impact signal if the impact meets threshold impact criteria. The impact signal identifies an expected location of a print area (118) in the zone. The print area meets one of plural different print-area location criteria respectively corresponding to plural changed colors materially different from the principal color. Responsive to the impact signal, a controller (702) determines which location criterion is met by the print area and provides an initiation signal at a corresponding condition. The impact-dependent portion responds to the initiation signal by temporarily appearing along the print area as the changed color for that location criterion.

The present disclosure provides an exercise monitoring device. The exercise monitoring device comprises a sensor module, a processing module, a storage module, and a user interface. The present disclosure also provides a method for estimating maximal oxygen consumption and/or future total exercise time by obtaining a person's physiological data and exercise data. The present disclosure further provides a method for calibrating the future total exercise time by environmental conditions to form an environmental specific total exercise time.

An electromechanical device for simulation of physical exercise with legs and arms includes two pedals mounted on two contiguous pantographs, with parallel supporting arms that are positioned in a predominantly vertical sense, with an orthogonal junction and parallel arms which are articulated, in a predominantly horizontal sense, onto the frame of the device and which always move in opposing directions left and right, through traverses which are articulated on vertical and horizontal axles, respectively, connected to vertical and horizontal parallel bars by means of risers.

A training device for use with a bicycle includes a shuttle guide member including a lower end and an upper end that define an axis therebetween. A shuttle is operably coupleable to a front end of the bicycle and translatable along the axis by a drive coupled to the shuttle. When coupled to the front end of the bicycle, translation of the shuttle along the axis by the drive results in each of a rotation of the shuttle guide member about a pivot and a change in elevation of the front end of the bicycle.

A system for respiratory training including a housing, a respiratory air channel disposed within the housing, a sensor configured to detect a breathing indicator and transmit a breathing indicator signal, a haptic device disposed within the housing, a processor operatively coupled to the sensor and the haptic device, and a memory device operatively coupled to the processor. The memory device includes instructions that, when executed by the processor, cause the processor to receive the breathing indicator signal from the sensor; generate a breath determination based on the breathing indicator signal; and responsive to the breath determination, cause the haptic device to generate a vibration.

A balance training system includes a moving carriage that moves on a moving surface, and a detection unit that detects a load received from training person's feet, and drives a driving unit based on the load's center of gravity of the feet to control movement of the moving carriage. A boarding plate is divided into a front plate on which a toe side of the feet is placed and a rear plate on which a heel side of the feet is placed. The detection unit includes right and left front load sensors, respectively provided with tilts to right and left foot sides, on a rear surface side opposite to the boarding surface of the front plate, and right and left rear load sensors, respectively provided with tilts to the right and left foot sides, on a rear surface side opposite to the boarding surface of the rear plate.

Among other things, a rowing technology includes a first rowing machine having an electromagnetic brake providing a resistance to a rower of the machine in each rowing stroke of a series of rowing strokes of the rower An electronic controller causes the resistance of the electromagnetic brake to vary over each rowing stroke in a profile that emulates resistance to which another rower in a shell on water or on a second rowing machine is subjected in each rowing stroke of a corresponding series of rowing strokes.

An apparatus for testing and exercising pelvic floor musculature, the apparatus comprising an elongate housing adapted for a pelvic floor aperture. The housing accommodates an oscillator and an accelerometer connected to a signal processor configured for communicating signals representative of values read from the accelerometer. A result is calculated from an applied oscillation and a response measured, and used for characterizing the musculature. In one embodiment the frequency resulting in the greatest response from the musculature is measured, and this frequency is applied during exercise.

Disclosed is a smart, physiology monitoring mouthguard (SPMM) system and method for capturing various physiological data of athletes in real-time for health monitoring. The system is configured to provide real-time and/or recorded physiological data of an athlete to a user, and may be configured to record physiological data of the athlete for later retrieval using sensors and communication systems. Sensors may be chosen based on the anticipated activity or sport, the health and age of the athlete, and size and power requirements of the device. Sensors may include accelerometers, gyroscopes, thermometers, hydrometers, pH, electrolyte (e.g., potassium, sodium, etc.) sensors, and the like. These and other sensors may be configured to measure different physiological data of the athlete, including impact, body temperature, hydration, illness, heart rate, and the like. In some embodiments, sensors on the mouthguard are integrated with external sensors (e.g., accelerometers on a helmet, chest-worn heart rate monitor) on the athlete to provide additional or more accurate physiological data.

Systems and methods for identifying a condition of a user. A treatment apparatus is configured to be manipulated by the user for performing an exercise, and an interface is communicably coupled to the treatment apparatus. One or more sensors are configured to sense one or more characteristics of an anatomical structure of the user. A processing device and a memory is communicatively coupled to the processing device. The memory includes computer readable instructions, that when executed by the processing device, cause the processing device to: receive, from the sensors, one or more sensor inputs representative of the one or more of characteristics of the anatomical structures; calculate an infection probability of a disease based on the one or more characteristics of the anatomical structures; and output, to the interface, a representation of the infection probability.
