Sporting event television broadcast equipment and systems, particularly for football games, pickups live audio from the teams' coaches for inclusion in the broadcast of the game, thereby greatly enhancing the viewing experience for television viewers of the game. The audio feeds can include always-on microphone pickup from each team's head coach, as well as offensive and defensive play calls that are radioed from each team's assistant coaches to players on the field.

Wireless power receivers include a first inductive element featuring a planar coil occupying a first plane and having first and second terminals, a first capacitive element connected to the first terminal, a second capacitive element connected to the first capacitive element at a third terminal and to the second terminal, a rectifier connected to the second terminal and third terminal such that an oscillating magnetic field will induce a current in the first inductive element, resulting in a voltage across the input of the rectifier, a communications modulation circuit, and a layer of magnetic material centered over the planar coil in a second plane parallel to the first plane.

Video display systems comprising a video display and a camera assembly are shown and described. In one example, video cameras may be stowed in and deployed from a compartment proximate the upper surface of the display and configured to deploy in an arc-like motion and for rotation about a center of the video camera housing itself. In other examples, video cameras may be aligned with openings in the frame of the television screen and operatively connected to shutter plates that selectively admit light to or block light from the camera. In a further example, video cameras may be provided on motorized mounts that are attached to the frame to collect multiple images for video processing tasks to enhance the video image in a variety of ways.

Methods and apparatus provide for processing information for a head-mounted display for blocking out an outside world from a user's vision when worn by the user to present a video, by carrying out actions comprising: measuring outside world information related to a boundary of an area within which user movement is acceptable; presenting, at a user interface, the outside world information; detecting, based on the outside world information, a change to the boundary; generating, based on the change, notification information about at least one of the boundary or the user movement relative to the boundary; and presenting, at the user interface or a different user interface, the notification information as a notification.

A modular mounting system for attaching multiple electronic display devices to a wall in an array. The system provides for vertical attachment of multiple electronic displays to a single module, and for vertical and horizontal attachment of multiple modules. The disclosed modular system enables multiple displays to be mounted in a virtually unlimited number of shapes as well as the standard square and rectangular arrays.

A display apparatus includes a display panel displaying an image; a top chassis provided along an outer periphery of the display panel and supporting the display panel, the top chassis including a magnet fastening portion therein; a chassis cover provided on an exterior of the top chassis and covering the top chassis; a magnet provided on the magnet fastening portion and configured to allow the chassis cover to be detachably mounted to the top chassis; and an elastic bracket configured to fasten the magnet to the magnet fastening portion, the elastic bracket may include a bracket body to which the magnet is mounted and an interference portion configured to interfere with the magnet fastening portion.

A virtual object display device comprises a display and a display control device configured to perform display control of the display. The display control device includes: a coordinate system calculation unit configured to detect movement and rotation of the virtual object display device in a real world, and use an inertial coordinate system in which a coordinate origin thereof follows the movement of the virtual object display device and an effective field of view of the display is rotated therein in accordance with the rotation of the virtual object display device so as to define an arrangement position of an inertial coordinate system virtual object; and a display control unit configured to, when the inertial coordinate system virtual object is included in the effective field of view of the display, display the inertial coordinate system virtual object within the effective field of view.

The utility model provides a television (TV) mount structure with an adjustable support force. The TV mount structure includes a first post, a second post, and multiple balancing devices, where the first post includes one end connected to a TV and the other end provided with a moving part of the balancing device; a stationary part of the balancing device is fixed at one end of the second post; and the second post and the first post are parallel, and movably connected axially. The utility model relies on the balancing devices to provide a constant support force to keep the TV at any height position without the need to lock the TV, saving time and labor. The utility model can adjust the constant support force to support TVs of different weights by combining the multiple balancing devices, and further increase the support weight by combining multiple TV mount structures with an adjustable support force.
