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.

Swimming goggles have a left-eye covering and a right-eye covering, each having a corresponding transparent window that defines a field of view and each further having a seal extending between the transparent window and the swimmer's face and formed to exclude water. A near-eye display is in signal communication with an image processor and forms a virtual image in the left- or right-eye field of view.

Embodiments herein are directed to an aquatic exercising assembly. The aquatic exercising assembly includes a container having a liquid retention portion. The liquid retention portion includes a bottom wall, a pair of opposing sidewalls, and a pair of opposing end walls, a pedal assembly and a paddle assembly. The pedal assembly is rotatably coupled to the one of the pair of opposing end walls. The paddle assembly is coupled to each one of the pair of opposing sidewalls. The paddle assembly is movable between a rearward position and a forward position in a longitudinal direction. The pedal assembly is rotatably moved by a lower body movement of a user and the paddle assembly is moved by an upper body movement of the user.

An object is to provide an iron golf club head that has high drainage performance and facilitates application of backspin also in a wet state. In an iron golf club head including a plurality of scorelines in a face surface, a microgroove including at least an inclined groove is included between the scorelines, the microgroove extending in a heel leading edge-toe top edge direction to be connected to an upper scoreline.

A modular and dynamic force apparatus for adjusting standard and dynamic torque-to-linear forces during physical activity in real-time, the apparatus including a force module, a user device and an apparatus tracking processing unit. The force module includes an open hub attachment point, wherein the open hub attaches the apparatus to an external source, one or more sensors measuring data for physical activity efficiency, an internal processor, wireless radio and force sensor module, a variable length cable, a force generating component, and motor controls. The internal processor, wireless radio and force sensor module includes an apparatus tracking measurement unit (“ATMU”) adapted to measure data, a first electronic communications channel for transmitting the measured data to an apparatus tracking processing unit (“ATPU”), and a second electronic communications channel for transmitting one or more apparatus conditions data to adjust dynamic forces. The user device receives one or more apparatus conditions data over the second electronic communications channel for real-time notification and/or adjustments to the user. The user interface includes a display that provides feedback and an apparatus tracking processing unit (“ATPU”). The ATPU includes the first electronic communications channel for receiving the measured data from the ATMU, a microprocessor, a memory storage area, a database stored in the memory storage area, and a tracking processing module located in the memory storage are. The database stores a first set of evaluation rules and a second set of evaluation rules, the first set of evaluation rules corresponding to one or more tracking parameters, and the second set of evaluation rules corresponding to the one or more apparatus conditions. The tracking processing includes program instructions that, when executed by the microprocessor, causes the microprocessor to determine the one or more tracking parameters using the measured data and the first set of evaluation rules, and determine the one or more apparatus conditions data using the one or more tracking parameters and the second set of evaluation rules.
