A golfer-oriented information providing method includes steps of inputting needs information regarding a golf swing to a computer, inputting swing attention points and advice information with an information provision priority, inputting reference golf swing information, importing first needs information of a first golfer, inputting first golf swing information of the first golfer, retrieving first reference golf swing information based on the first needs information by the computer, extracting a difference between the first reference golf swing information and the first golf swing information regarding the swing attention points of the first needs information, and selecting the advice information based on a magnitude of the difference and the information provision priority and providing the selected advice information to the first golfer.

In one example, a muscle exercise device includes a first arm and a second arm rotatably connected to the first arm, and the second arm and the first arm are configured to cooperatively define a recess having a shape that changes as one of the first arm and the second arm moves toward, or away from, the other of the first arm and the second arm. The muscle exercise device further includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm so as to assume a configuration similar to the shape of the recess. Finally, a wireless transmitter chip is disposed in either the first arm or the second arm, and the wireless transmitter chip is responsive to communications from an app residing on a user device.

A magnetic clutch transitions a drivetrain or flywheel between a freewheel or unlocked mode or configuration and a locked or fixed gear mode or configuration. The magnetic clutch includes a rotor rotationally fixed to the pedals of the drivetrain. An armature is connected to the flywheel. A field coil generates a magnetic field which causes the armature to move to the flywheel. Friction between the armature and the rotor rotationally fixes the flywheel to the rotor.

A video acoustical method determines an impact point of a thrown body on a landing area, in particular for athletics throws disciplines, the body describing a trajectory in the air from a take-off area towards the landing area, the impact point being defined by the body hitting on the landing area. The method includes acquiring video exposures of the body impact on the landing area to a frame rate, each exposure showing one position of the body; calculating the body trajectory during at least the body impact on the landing area with the video exposures analysis; detecting an acoustical impact time due to the body hitting on the landing area; and determining the body impact point on the calculated trajectory with the detected acoustical impact time. A video acoustical system can determine an impact point of a thrown body on a landing area.

An exercise rating and improvement system comprising: a feature amount extraction unit for extracting, from information obtained from a subject, a feature amount about exercise efficiency; an rating unit for rating exercise efficiency of the subject by comparing the extracted feature amount and a feature amount to be compared; and an improvement information providing unit for providing, on the basis of the rating result, information such that the feature amount of the subject approaches the feature amount to be compared.

A system and method for evaluation, detection, conditioning, and treatment of neurological functioning and conditions which uses data obtained while a person is engaged in simultaneously in a range of primary physical tasks combined with defined types of associative activity, such as listening, reading, speaking, mathematics, logic puzzles, navigation of a virtual environment, recall of past stimuli, etc. The data from the physical and associative activities are combined to generate a composite functioning score visualization indicating the relative functioning of areas aspects of neurological functioning; including those in which deficiencies may be present, which are early indicators of possible neurological conditions. Through algorithmic recommendations combined with expert and user input, a conditioning regimen targeting neurological aspects of interest paired with periodic testing allows the user to track their progress in these areas over time.

A tennis ball retriever for retrieving a tennis ball on and about a tennis court and for controllably releasing the ball includes a front-end ball collector having two spaced-apart blades defining a ball collection space. The retriever includes a means for gripping and securing a ball positioned at the fore end, and one or more detents for retaining the collected ball in the collection space until a programmed or manually-directed release toward a target location such as a tennis baseline. The retriever includes a processor-controller for controlling and directing the retriever during a retrieval session. The retriever may be remote-controlled such as by voice commands.

Interactive/smart resistance band training systems include one or more resistance bands connected to a force sensing unit that registers the force exerted by a user on handles connected to the bands. The sensing unit operates effectively regardless of whether the user is training with one handle individually, or with two handles being pulled in parallel or non-parallel directions. The systems may correct the force readings to account for non-alignment between the force-measurement axis of the force sensing unit and the directions in which the user applies force to the resistance bands. The systems may guide a user through exercise sessions tailored to the fitness level of the user; may display the force readings, calories burned, and other performance parameters and goals on a continuous, real-time basis; may summarize the result of the exercise session; and may recommend subsequent exercise sessions based on the performance of the user.

A smart cricket bat and a process of fabrication of the same is disclosed. The cricket bat includes an electronic system includes a plurality of sensors with sensor fusion to remove bias in sensed data. The plurality of sensors measure accurate data representative of rate of change of velocity, angular speed, orientation of the smart cricket bat, pressure exerted on the smart cricket bat by a ball, a pressure exerted on the handle unit by a hand grip of the batsman during swing of the smart cricket bat and one or more audio signals. The electronic system also includes a processing unit configured to process sensed data to calculate one or more metrics associated with batting. The electronic system also includes a transceiver unit configured to transmit one or more calculated metrics to a user's computing device.

A method includes receiving electronic content via a network, the electronic content comprising an exercise class, and receiving user data associated with a user participating in the exercise class using an exercise machine. The method also includes generating an executable control for a user interface based at least in part on the user data, and providing the executable control, via a display of the exercise machine, while the user is participating in the exercise class. In such a method, the executable control is operable to modify a parameter of the exercise machine while the user is participating in the exercise class.
