A wood-type golf club head includes first and second ribs projecting from a bottom club head wall portion, the wall portion, the first rib, and the second rib forming an elongate recess defining a weight path. A weight element is translatable along the weight path and includes a first weight portion, a second weight portion, and a fastener, the first and second ribs each being interposed between the first weight portion and the second weight portion such that the first weight portion is located proximate the club head wall portion and the second weight portion is located distal the club head wall portion. The second weight portion has a contact surface that includes a recessed region, and when the weight element is in a secured position, at least a portion of the first weight portion is located within the recessed region.

A system, methods and apparatus for powered monofin that propels a swimmer through water uses one of two modes of power: 1. An electric-assist mode, in which the propulsor responds to a swimmer's kick by multiplying the work of the swimmer; 2. Inverse mode, in which the propulsor deactivates when the swimmer is working. In this mode, propulsion is inversely related to the work of the swimmer. As the swimmer does more work, power from the monofin is reduced, to a predetermined, average level of propulsion. As the swimmer does less work propulsion increases to the predetermined level.

A healthy motion environment managing apparatus includes a wearable intelligent equipment, an environment adjusting equipment, a fitness equipment and an environment parameter collecting equipment. The wearable intelligent equipment includes an input unit, a memory unit, a processing unit and a communication unit. The environment parameter collecting equipment configured for sending a value of a collected current environment parameter to the wearable intelligent equipment. The processing unit compares a difference of the value of the collected current environment parameter and a value of one of optimum motion environment parameters, if the difference is larger than a set threshold, a start instruction is sent to the environment adjusting equipment via the communication unit. The invention can adjust the motion environment quickly and conveniently and can improve the user experience greatly.

Systems and methods providing statistical analytics of golf performance for coaching including text, tabular, graphic, and image-based outputs that include trends information for the golfer, all based upon actual golf play on course situations, wherein the golfer inputs shot data during play, without interrupting the flow of the game, and uploads the shot data for analytics and review online, and wherein all information related to a given user are reviewable by an authorized coach user through a web-based coach access account. The system is further operable to provide the coach user rights for providing corrective or instructive feedback to the user, including visual recommendations such as modified target areas.

Disclosed is a water flow control device for swimming training that includes a swimming training device and a main water inlet pipe and a main water outlet pipe. The swimming training device includes at least a swimming pump. The main water inlet pipe and the main water outlet pipe are connected with the swimming pump. The water inlet of the main water inlet pipe is communicated with a swimming pool and a water outlet of the main water outlet pipe is connected with a jet nozzle. A filter device includes at least a filter pump, a filter sterilization device. A filter water inlet pipe and a filter water outlet pipe are connected with the filter pump. The filter water inlet pipe is communicated with the swimming pool through the filter sterilization device and the filter water outlet pipe communicated with the main water inlet pipe.

Percussive interactive device characterized in that it is composed of an external polyhedric case of deformable material and of an internal case housing an electronic device, whose purpose is to detect external forces applied on said device and to transmit the data collected, once converted into electronic data for audio applications, to an external device used to process and emit sound.

Devices systems and methods are disclosed. Among other things, the devices systems and methods can facilitate ergonomic gripping of a handle; conform to the shape of a wrist; enhance golf techniques or performance; enhance racket sport technique or performance; protect a head of a user engaged in contact sports or other hazardous activities; identify concussions, in some cases in substantially real time; provide sterilization of garments; control surgical robots; allow for medical treatment of multiple subjects without disrobing; provide biometric or other data; and/or be used to train muscles or body parts for, for example, performing specified tasks using a body part.

Disclosed herein are systems and methods for determining when one or more golf clubs are in use or in a golf bag. Alerts can be provided if it is determined that the golfer has misplaced one or more golf clubs. The disclosed systems and methods can also be used to determine whether other objects have been misplaced from a typical storage container.

Examples are disclosed that relate to methods, computing devices, and systems for determining a user's readiness for an operational task. One example provides a method comprising, during a training phase, receiving training input data including, for each user training session, a training data pair including, as input, a distance of travel, a mode of travel, and one or more environmental conditions, and as ground truth output, a time elapsed for performance of the training task. An artificial intelligence (AI) performance model is trained to model user performance of the training task based on the training data pairs. During a run-time phase, operational input data is received that is associated with an operational task performed by the user. The performance model is used to infer a predicted time elapsed for performance of the operational task.
