A non-interdependent displacement measuring device for converting a rotary motion to a linear motion is disclosed, which includes a driving unit, a detection unit, and a resistance device. The driving unit includes an adjustment section and a driving section. The detection unit is arranged in the adjustment section. The driving section is connected to the resistance device. The detection unit includes a sensing module and a transmission module, and the detection unit is arranged in the adjustment section, so that when the adjustment section rotates, the detection unit detects turns and an angle of rotation of the adjustment section to generate a detection signal, which, after being subjected to calculation, is transmitted through the transmission module to the electronic device to display the level of an resistance, so as to overcome the drawbacks of the prior art that accuracy is poor, calibration is difficult, and fabrication is difficult due to a magnet and a sensor being arranged as two separate parts.

Measuring device / sensor system for measuring, transferring and processing of relevant performance data from training and competition in contact sports, in particular the physical contact and its force effect

In practice and as far as possible, performance data in contact sports, in particular those of factual contact and force effect of relevant objects and persons to each other, are not surveyed separately but evaluated subjectively. In contact sports like martial arts this is especially critical, because an occurred contact and its force effect are the significant success data in these sports. In other types of contact sports, e.g. ball sports one is concentrated on the performance data, that lead to goal achievement (e.g. goal scoring) and is not looking objectively into the performance of participants for, for example, draw conclusions about the correct technique execution at any time in a game or competition. Though there are already measuring devices for some contact sports for detecting force effect and contact, these are limited to several defined single sensors and applications. Therefore it may be possible to make objective measurement but in case of doubt, a subjective evaluation of technique and point assignment is still necessary. This invention contains a system of measuring devices, that can, especially in martial arts sports, improve the point assignment and in other contact sports the evaluation of techniques. These special measuring devices for contact measuring and its movement and acceleration sensors, display systems and hardware interfaces can be combined with software interfaces and be tailored to fit different applications. In case of martial arts sports, the configuration of protective equipment with these measuring devices is one use case, in which the measuring devices detect all relevant data like contact, force effect and movement direction, that can be used for competition decisions.

The rotator cuff exercise device includes a ring unit, a mounting board, and a pair of mounting tracks. The rotator cuff exercise device may be adapted to exercise joints and muscles or may prevent the loss of flexibility in an elbow or a shoulder blade. The rotator cuff exercise device may be particularly suited for therapy after an injury involving a rotator cuff. A handle may detachably couple to an individual rotatable ring selected from one or more rotatable rings of the ring unit and may be adapted to be grasped by a hand of the user. The handle may be operable to move the individual rotatable ring in a circular motion. The circular motion of the handle may exercise the joints and muscles of the user.

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.

An exercise device comprises a rigid rod having a first and second ends, a plurality of light sources arranged in a row along at least a portion of an axis extending between the first and second ends of the rigid rod, at least one load sensor for detecting an applied longitudinal force, and a processor coupled to the at least one load sensor and to the plurality of light sources. The processor is configured to execute machine-executable instructions that cause the processor to obtain a signal indicating a magnitude of the applied longitudinal force, and cause a subset of the plurality of light sources to emit light. A ratio of a number of light sources in the subset to a total number of the plurality of light sources represents the magnitude of the applied longitudinal force relative to a reference longitudinal force.

In one aspect of the disclosure, a method that involves keeping state of a video workout program may include communicatively coupling a server in a cloud network to an exercise machine through a first network connection, communicatively coupling the server to a network device through a second network connection, the server providing a video workout program to the exercise machine for execution at the exercise machine to enable a user to perform at least a portion of a workout of the video workout program on the exercise machine, the server keeping state of the video workout program during execution of the video workout program based on inputs from the exercise machine and the network device, and taking an action based on the state. The action may include synchronizing multiple displays, adaptively scaling the video workout program, and/or generating and providing an exercise machine control command to the exercise machine.

A walking support system includes: an information output device (260); a motion detector (220) which detects a motion of a user; a foot landing position detector (230) which detect a foot landing position of the user; a determiner (240) which determines a recommended foot landing position which is a landing position of the feet suitable for stabilizing motions of a gait of the user on the basis of motions of a gait of the user detected by the motion detector, the foot landing position detected by the foot landing position detector, and dynamics; and an output controller (250) which outputs information indicating the recommended foot landing position determined by the determiner to the information output device.

A system for a manual treadmill having a tread that rotates around a front axle and a rear axle and side rails on opposing sides of the tread includes a brake configured to slow rotation of at least one of the front axle or the rear axle, a controller, and a first presence sensor in communication with the controller, the first presence sensor positioned on a side rail and configured to detect a user on the side rail. The brake is not normally engaged during operation of the treadmill when the tread is moving and the first presence sensor does not detect the user on the side rail. The controller is configured to, in response to the first presence sensor subsequently detecting the user on the side rail, engage the brake.

The animation preparing device includes at least one processor. The processor acquires exercise data concerning an exercise done by a user or the exercise that the user is doing. In a case where there exists a plurality of causes for a characteristic point of the user that has been detected based on the acquired exercise data, the processor prepares, from the exercise data, a first user animation represented in a first direction of line of sight as an animation of the exercise done by the user or the exercise that the user is doing in order to indicate a first cause for the characteristic point, and prepares a second user animation represented in a second direction of line of sight that is separate from the first line of sight in order to indicate a second cause for the characteristic point that is separate from the first cause.

Athletic performance monitoring systems and methods, many of which utilize, in some manner, global positioning satellite (“GPS”) data, provide data and information to athletes and/or to equipment used by athletes during an athletic event. Such systems and methods may provide route information to athletes and/or their trainers, e.g., for pre-event planning, goal setting, and calibration purposes. Such systems and methods optionally may provide real time information to the athlete while the event takes place, e.g., to assist in reaching the pre-set goals. Additionally, data and information collected by such systems and methods may assist in post-event analysis for athletes and their trainers, e.g., to evaluate past performances and to assist in improving future performances.
