Exercise devices, systems, and methods are disclosed. One exercise device includes weights, a shell assembly, and a base assembly. The shell assembly has a shell defining an interior sized to receive the weights. The shell assembly also has a shaft coupled for rotation relative to the shell. When the weights are received within the interior of the shell, rotation of the shaft relative to the shell selectively couples the shaft with one or more weights. The base assembly has a base configured to support the weights. The base assembly also has a driver configured to be coupled to the shaft when the shell assembly is supported by the base. The driver of the base assembly is configured to rotate the shaft relative to the shell when the driver is coupled to the shaft to selectively couple the shaft with the one or more weights.

An interactive sports management device combined with human physiological information and sports information includes a user module, an exercise module and a management module, wherein the user module is used to detect the physiological information of the user, and transmit the user identifier and the physiological information to the exerciser module. The exercise module is used to collect the sports information of the sports fitness equipment, and transmit the user identifier, the physiological information, the exerciser identifier and the sports information to the management module. The management module transmits the management information to the exerciser module. In this way, the sports information generated when the specific person uses the specific sports fitness equipment for exercise is combined with the human physiological information into the personalized information.

A device for logging exercise data, the device includes a body for engaging with an exercise machine; an electrical system with a power source incorporated into the body and to record data; an image sensor incorporated into the body and to capture an image; a motion sensor incorporated into the body and to detect movement; the image sensor determines a weight load associated with the exercise machine; the motion sensor detects and records a number of repetitions of movement; and the device creates an exercise log associated with a user's workout.

A cycling shoe for measuring power includes a sole having a pocket in the bottom of the sole. A sensor platform having a plurality of sensors, at least one sensor on a top of the sensor platform and at least one sensor on the bottom of the sensor platform, is inserted into the pocket. A platform cover and a cleat are attached to the sole over the sensors. Force applied to a pedal clipped to the cleat is measured and processed.

A golf guide system includes a terminal to be carried by a user who is playing golf, and a location information transmitter provided in the terminal and a hole and transmitting location information of the hole to the terminal, generates a distance by measuring a distance between the terminal and the location information transmitter, and guides a distance and a recommendable club based on analysis of environment and geography between the terminal and the hole.

Devices and methods for training the tongue and other muscles of the throat and upper respiratory airway to alleviate symptoms of snoring and the Obstructive Sleep Apnea Syndrome (OSAS) are provided. A threshold-load trainer, or similar device, having a biased tongue resistance pad is used for strengthening the muscles of the tongue to inhibit narrowing or obstruction of the upper respiratory airway, particularly during a state of relaxation or sleep. The threshold-load trainer embodiments of the subject invention can specifically target the genioglossus muscle under the tongue (the major tongue protruder) and other muscles of the throat and upper respiratory pathway, so as to improve muscle tonus.

A liquid discharge head includes: an individual channel having an inlet and an outlet, the individual channel including: a nozzle, an upstream-side pressure chamber arranged between the inlet and the nozzle, a downstream-side pressure chamber arranged between the outlet and the nozzle, an upstream-side throttle channel connecting the inlet and the upstream-side pressure chamber, and a downstream-side throttle channel connecting the outlet and the downstream-side pressure chamber; a supply channel connected to the inlet and configured to supply liquid to the individual channel; a recovery channel connected to the outlet and configured to recover the liquid from the individual channel; an upstream-side actuator configured to apply pressure to the liquid inside the upstream-side pressure chamber; and a downstream-side actuator configured to apply the pressure to the liquid inside the downstream-side pressure chamber. The channel resistance of the downstream-side throttle channel is smaller than that of the upstream-side throttle channel.

A Bluetooth chip designed to track proximity and play a sound, along with an accelerometer, that is embedded inside of a golf ball is disclosed. The technology inside the balls allows it to be found quickly through proximity and sound, and the app gives a golfer helpful analytical data.

This invention is embodied by a controlled, variable tension line, payout reel machine. A system of sensors detect line tension and line distance paid out, location, and transmit through wired and unwired communication to a microprocessor. The microprocessor is co-located with the reel structure, which in turn applies, via a brake feature, resistance to the reel which is paying out the line being pulled by the user. This invention pertains to all applications where it is desirable to control the tension in a line paid out from a reel or reel. As stated, the payout motive force is supplied by the person, animal or apparatus attached to the end of the line, opposite the reel. The invention applies to the field of precise and measured control of line tension for sport, sport training, performance testing.
