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 patient support apparatus may include a frame. A control module may be positioned on the frame. A graphical user interface may be in communication with the control module. An exercise apparatus may be coupled to the frame and may be in communication with the control module.

Disclosed is a smart barbell (1) which comprises a first bar part (10) and a second bar part (20), each arranged for carrying one or more weights, the first bar part (10) and the second bar part (20) extends along a longitudinal axis (X-X). The barbell (1) further comprises a central bar part (30) arranged between the first and the second bar parts (10, 20) and which is connected to the first bar part (10) and the second bar part (20) and extends along the longitudinal axis (X-X). At least one of the first bar part (10) and the second bar part (20) comprises a cavity (12, 22), in which at least one sensor (40, 50) is arranged for registration of movements of the barbell (1) and for wireless communication with a data analyzing unit (100).

Disclosed is a method, a device, a system and/or a manufacture of training utilizing a target comprising strike sectors and/or a mat comprising position sectors indicated to the user. In one embodiment, a method for combat training, athletic training, and workout includes determining a position sector ID from a training file associated with a position sector visually identified on a mat including a position detector. A strike sector ID is determined associated with a strike sector on a strike target capable comprising a strike detector and capable of receiving a strike from a human extremity. A first indicator signal is generated to communicate the foot placement to the user and a second indicator signal communicates the strike sector. A strike signal is received from the strike and/or a position signal is received from the foot placement on the mat. The user's strike and/or positioning performance may be assessed.

An interactive bowling system using scoring systems and/or other computer infrastructures which interact with visual and/or audio effects within the bowling center. The system includes a management system having stored therein instructions to provide special effects associated with one or more events to one or more special effects components. Upon an occurrence of an event, the management system: determines that the occurrence of the event is associated with one or more special effects; and provides the instructions to the one or more special effects components to effectuate the special effects associated with the one or more events.

Various systems and methods that enhance an exercise or other physical activity performed by a user are described. In some embodiments, a classification system communicates with a media hub to receive images and perform various methods for classifying or detecting poses, exercises, and/or movements performed by a user during an activity. In some embodiments, the systems and methods include a movements database (dB) that stores information as entries relating individual movements to data associated with the individual movements. Various systems, including class generation systems and body focus/activity systems, can utilize the movements database when presenting class content to users and/or presenting exercise information (e.g., muscle groups worked or targeted) to the users.

A device including a visual or audible 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 is disclosed. The device may be used as a toy for amusement, and may be shaped like a play ball or as a handheld unit. The device may be powered from a battery, which may be charged from an AC power 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 the sensed acceleration magnitude or direction, such as sensing the crossing 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.

An electronic device is provided. The electronic device includes an actuator related to a joint of a user of the electronic device, at least one sensor, memory storing one or more computer programs, and one or more processors operatively coupled to the actuator, the at least one sensor, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors, cause the electronic device to adjust the strength of the rotary motion of the joint to a first strength indicated by information related to the user, use the at least one sensor to identify data representing the rotary motion of the joint after adjusting the strength of the rotary motion to the first strength, and, based on the identified data, adjust the strength of the rotary motion from the first strength to a second strength different from the first strength at least based on identifying that the rotary motion has stopped for a designated duration.
