A football yardage chain apparatus for more accurately detecting first downs includes a unit housing having a pole aperture extending from a top side through a bottom side and a channel extending through to the pole aperture from proximal the bottom side to the top side. A pole is coupled through the pole aperture and a chain connector is coupled proximal a bottom end of the pole. A marker bar has a hinge coupled within the channel and swingingly moves between a stored position parallel with the pole and an alternative extended position configured to extend to a height proximal a nose of a football resting horizontally on the ground. A back side of the marker bar lies coplanar with a tangent plane of the pole at a point of union with the chain connector.

A method determines running phases of a user on a treadmill having first and second rotating elements rotating about respective rotational axes transverse to a longitudinal axis of the treadmill. A physical exercise surface connects to the rotating elements. An electric motor operatively associated with one rotating element rotates the rotating elements and the physical exercise surface. A processor connects to the electric motor and controls the electric motor. The processor determines a magnitude variable over time, which is correlated to user interaction with the exercise surface while exercising and has a periodic trend. The processor determines time instants of at least two points of the periodic trend. The time instants of each point representing instants of user interaction with the exercise surface. The processor determines a running phase of the user on the exercise surface as a function of the respective time instants of the periodic trend.

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.

An exercise machine comprises a motor. The exercise machine comprises a lockable translatable mount. The exercise machine comprises a cable coupled to the motor via the lockable translatable mount. The exercise machine comprises a sensor coupled to the lockable translatable mount. The sensor is used at least in part to determine mount lock state.

A system and method for targeted neurological treatment using brainwave entrainment therapy with passive treatment that allows for targeted treatment of particular areas of the brain, particular neurological functions, particular neurological states, and combinations of areas, functions, and states. The system and method receive gait parameters for an individual and compare those against a database of historical gait data to determine if an onset neurodegenerative condition is present, and applies a brainwave entrainment therapy responsive to the determination of the condition. The system and method receive a neurological assessment identifying areas of the brain or neurological functions to be treated, select one or more treatment modalities and frequencies, select a treatment regimen, and apply brainwave entrainment using a treatment regimen while the subject engages in dual-task activities selected to stimulate the areas of the brain, neurological functions, or neurological states to be treated, enhanced, or altered.

Disclosed herein are robust disposable alternating tangential flow (ATF) housing and diaphragm pump units and associated methods of manufacturing, testing, wetting, and using the same.

Computing device enhanced training environment system comprising a computing device, I/O subsystem for permitting a user to enter at least one attribute of the training or of the trainee, a plurality of sensors for generating sensory information, a training environment in which a training activity takes place, a database containing training related information. The computing device enhanced training environment system configured for at least one of the following: design a training program for a plurality of users, monitor training program performance, monitor training performance, instruct a user about the training, determine and/or set difficulty level in training apparatus.

An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.

A basketball goal system comprising a backboard assembly and suspension frame affixed to the back surface, a suspension structure connected to the suspension frame of the backboard and a goal indication system which interfaces to at least one of the suspension structure or backboard to cause an indication (of various colors) to be presented via the suspension system and/or the backboard which indication relates to the shot points associated with a shot attempted at the goal. The goal indication system causes presentation of a cue on a front surface of the backboard, which cue is of a color corresponding to shot points. The backboard elements and light emission of the suspension frame can be controlled synchronously or asynchronously.

Systems and methods for adjusting resistance on an exercise cycle having a frame and a flywheel include calibration, homing and auto-follow routines. A resistance apparatus comprising an actuator is configured to selectively position the resistance apparatus relative to the flywheel, wherein a distance between the resistance apparatus to the flywheel corresponds to resistance applied to the flywheel. Control components are configured to control operation of the resistance system in response to instructions, and a computing device is configured to output media for an exercise class to a user, the exercise class comprising one or more target resistance ranges corresponding to a segment of the exercise class. The computing device is further configured to selectively implement auto-follow logic configured to determine a target resistance value for a current segment of the exercise class and instruct the control components to adjust the resistance system to the target resistance value.
