A gate assembly device, which may include an pole with an arm and base coupled to the pole. The arm may be coupled to a sensor, and the sensor may measure whether movement was detected between the sensor and a ground surface. The sensor may also detect whether contact was made with the arm. The arm may be coupled to the pole with a coupling device, and the coupling device may be coupled to the pole at more than one height. The pole may be coupled to more than one arm, and the one or more arms may move between a stowed and deployed position.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

A video display device comprising; a display; an exercise amount detection sensor configured to detect an exercise amount of a viewer while the viewer is viewing content displayed and output sensor information; a timer that measures a viewing time; and a processor. The processor: acquires the viewing time from the timer; calculates the exercise amount of the viewer based on the sensor information acquired within a predetermined period of viewing time; compares the exercise amount with an exercise facilitation threshold for determining whether to facilitate exercise for the viewer; displays a specific object within a display area of the display when the exercise amount falls below the exercise facilitation threshold; and moves the specific object from an inside of the display area to an outside thereof in accordance with an external coordinate system expressing a position in a real space associated with a two-dimensional coordinate system in the display area.

In a system configured to perform active target updating according to a rehabilitation action of a user, a first rehabilitation action of the user is detected, and an avatar image that moves in accordance with the detected first rehabilitation action and a target image representing a target of the first rehabilitation action are displayed. The rehabilitation ability of the user is evaluated by comparing the first rehabilitation action and a target position represented by the target image, and the target position is updated in accordance with an evaluation result. Furthermore, a second rehabilitation action of the user during the first rehabilitation action is detected, and the rehabilitation ability is evaluated based on both the first rehabilitation action and the second rehabilitation action. In addition, when at least a predetermined evaluation is made only for the first rehabilitation action, the rehabilitation ability is evaluated based on both the first rehabilitation action and the second rehabilitation action.

A rotatable training mannequin used for training fighters or contact sports athletes is constructed of materials that mimic or simulate the upper human body. A sensor embedded in the training mannequin's head senses, detects, and transmits signals containing data for computer analysis. The data is related to motion parameters, which include linear and angular accelerations and velocities, of the training mannequin as a result of impacts and power strikes made by trainee to the training mannequin. Analysis provides feedback to the trainee related to the motion parameters to help the trainee learn proper footwork and where and how to make effective strikes. The parameter values obtained from the training mannequin can be calibrated and/or correlated against current or future real human parameter values due to strikes or other forces that produce damaging effects, such as concussions, and the training mannequin can be used to avoid or learn about concussions.

Wearable electronic devices that are designed to be worn on the head of a user while the user is swimming can determine swimming strokes and swimming performances of the user accurately using motion sensors. Using a sound speaker, the wearable electronic device can play music and provide audio feedback to the swimmer. By comparing the swimming performance of the swimmer wearing the device with previously recorded swimming data, the wearable electronic device can provide audio comparison results to the swimmer while the swimmer is swimming in water. To improve water resistance, magnetic switches are utilized as selection switches. The wearable electronic device can also support similar functions for other sports and physical activities.

An electronic sideline marker for use in football comprises a first display configured to display an indication of a down and a second display configured to display one or more timers. The second display may be configured to display a play clock, a go-clock, and/or a throw-clock. A play clock may first be displayed, and the marker may then receive an indication (e.g., a button press) that the football has been snapped, at which point display of the play clock may be replaced with display of a go-clock. The marker may be configured to output indications when the play clock, go-clock, and/or throw-clock expire. The marker may be configured to electronically communicate with one or more other markers for use in the football game, or one or more other remote electronic devices such as sensors in flag football belts, flags, and/or footballs.

A sports training safety system and method of operation thereof includes: a training dummy; a release attached to the training dummy; a delivery carriage mounted to the release; a delivery rail for supporting the delivery carriage; a transport system, attached to the delivery rail, for moving the delivery carriage and the training dummy along the delivery rail; and a controller.

Novel tools and techniques for teaching a player the proper alignment when addressing a golf ball. In one aspect, such tools and techniques provide an alignment aid that allows the player to visualize both the intended target line of the shot as well as the position of the ball relative to the player's stance, allowing the player to easily modify his stance to obtain the proper alignment.

Embodiments of the present disclosure are directed to play panels, and playground structures comprising such panels, that provide an interactive play activity for children. The play panels comprise at least a surface that is configured to provide an interactive element, a control unit, and a connection element configured to communicatively link an adaptive switch. A child may interact directly with one or more elements on the surface of the play panel to actuate the play activity. A child having a disability may also actuate the play activity using an adaptive switch that is communicatively connected to the play panel. In some embodiments, the control unit may be configured to operate the play activity differently depending on whether it is actuated by elements on the surface of the play panel or a connected adaptive switch.
