An isokinetic oscillation exercise device of an elongated flexible blade having a first and second end and a grip portion coupled to a middle portion of the elongated flexible blade. End caps coupled to said first and second ends adapted to storage. Further, a method is disclosed of manufacturing an isokinetic oscillation exercise device that provides a flexible elongated flexible blade, a grip portion injection molding, a pliable ring injection moldings, and end caps injection molding; slides the pliable rings on the elongated flexible blade separated by a length of the grip portion, overmolds a first-shot of the grip portion over the pliable rings, overmolds a second-shot of the grip portion to the first-shot of the grip portion to the elongated flexible blade, seals the first-shot to the second-shot of the grip portion against the pliable rings; and attaches the end caps to the elongated flexible blade.

An apparatus for hand tremor stabilization including a rotatable flywheel assembly mountable to a hand of a user. The rotatable flywheel assembly includes i) a flywheel having a flywheel mass, m, and a flywheel diameter, d, and ii) a prime mover adapted to rotate the flywheel at a rotational speed, r, about a flywheel rotation axis such that the rotatable flywheel assembly generates an angular momentum having a magnitude of between about 0.05 kgm2/s and about 0.30 kgm2/s.

A hopscotch trampoline has a trampoline with a bed suspended across a trampoline frame. The bed has a bed center, a bed middle, and a bed periphery. A trampoline length is greater than a trampoline width. A hopscotch field is formed on the bed. The hopscotch field includes successive areas. The successive areas are at least partially linearly oriented. Contact sensors mounted on each area and the contact sensors are electrically connected by an electrical connection and electrically connected to a control panel harness. A middle crossbar can extend underneath the bed and connecting a right vertical post to a left vertical post.

A stationary indoor “smart” training bicycle includes a unique combination of adjustable components to provide configurable dimensions to adjust the frame size of the indoor bicycle to properly fit a rider. A system is also provided to process a digital image of an outdoor bicycle and determine and translate dimensions and adjustments to the indoor bicycle to match one or more dimensions (lengths, angles, separations, etc.) of the outdoor bicycle.

A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive a physiological measure. The processor is further configured to display, via the display system, the physiological measure, wherein the display system is disposed in the eyewear so that the physiological measure is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle α from a forward direction.

Accessory systems configured to convert motion from a given exercise device into computer readable instructions for a given general-purpose computer. The accessory systems include a microcontroller and a sensor. The microcontroller is in data communication with the given general-purpose computer. The sensor is in data communication with the microcontroller and mounted in a position to monitor the given exercise device. The sensor is configured to detect motion of the given exercise device and to send motion data to the microcontroller. The microcontroller is programed with computer executable instructions to convert the motion data into computer readable instructions for the given general-purpose computer. In some examples, the accessory system includes a magnet, a first supplementary input, a second supplementary input, and/or a user input device.

An indoor, stationary, bicycle training device that provides advantages over conventional designs of exercise bicycles is provided. The stationary bicycle may include a tilting/pivoting mechanism to orient the indoor bicycle to simulate descending or climbing. The indoor bicycle may include flexible and resilient frame elements to support the indoor training device to move side-to-side under some riding situations thereby simulating the side-to-side swaying motion of an outdoor bicycle under the same riding situations. The indoor bicycle may include several combinations of frame adjustments to provide configurable dimensions of the indoor bicycle to adjust the frame to properly fit the rider, which may be adjusted based on corresponding dimensions of a user's outdoor bicycle. Still other aspects of the stationary bicycle device may aid in creating an “outdoor” feeling while using the device.

Provided is an air sensor, coupled to an air inlet of an air-filled product that is filled with air to maintain a shape thereof, the air sensor including: a connector coupled to the air inlet and communicated with an interior of the air-filled product, thereby allowing air in the air-filled product to be introduced into an interior of the connector; a silicon sensor provided inside the connector, thereby being operated by air pressure of the air-filled product; an impact sensor configured to detect an impact caused by an operation of the silicon sensor; and a PCB connected to the impact sensor, thereby displaying the number of times according to a detection signal of the impact sensor.

A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive an activity metric. The processor is further configured to display, via the display system, the activity metric, wherein the display system is disposed in the eyewear so that the activity metric is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle α from a forward direction.

A system for data collection during a game includes a positioning system for determining various locations of a user during the game, a tag reader for reading a passive RFID tag held in close proximity to the tag reader, and a processor for correlating the location of the user with the time at which a tag is read to enable action locations for the game to be determined.
