Systems, methods and articles of manufacture for affect a virtual world based n available electronic devices. A control node identifies electronic devices present within a physical environment. Embodiments detect a device type of a first electronic device and determine an API implemented by the first electronic device, based on the detected device type of the first electronic device. Electronic messages are transmitted to the first electronic device, via the one or more data communications networks. The electronic messages are formatted according to the determined API. One or more actions are determined for a first user for a first computer game, based on data received from the first electronic device via the one or more data communications networks, and a game state for the first computer game is updated, based on performance of the one or more actions.

A method for dividing one 7201080, 10801920, 2K, 4K, 8K or a 12K video segment into two equal segments using a mathematical aspect ratio calculation which by combining two equal 7201080, 10801920, 2K, 4K, 8K or 12K video segments to create one symmetrically mirrored 7201080, 10801920, 2K, 4K, 8K or a 12K video segment to make one three second to thirty minute video to be up loaded and played within video glasses, 3D software and 3D video glasses, 3D parallax software, micro SD memory cards, HD televsions, 3D televisions, virtual reality software and hardware, mobile media applications, computers and all video streaming internet applications including widescreen cinema standard and IMAX theatrical projections.

A method and an apparatus for applying an anesthetic includes a receptacle having an upper end, a substantially hollow interior, a lower end having a tube or nozzle extending therefrom, and an attachment for attaching to the barrel of a syringe or vice versa. The receptacle receives a container or canister containing an endothermic gas or vapor(propellant) that rapidly absorbs heat when released to the atmosphere. A depressible actuating member or trigger propels the gas or vapor through an outlet nozzle that is oriented to project a stream of gas or vapor along a delivery axis that intersects a delivery axis of the needle, therefore, the gas or vapor can be successively delivered to an injection site with minimal repositioning of the housing.

A cover device formed of a plastic or similar composition is structured for removable attachment over a bracket of an orthodontic appliance and includes a main plate with an outer front face, and top and bottom claws integrally formed with the main plate, curling behind the main plate, and each terminating at distal ends in spaced, opposing relation to each other behind the main plate. The main plate is bowed outwardly from top to bottom to allow the claws to flex away from each other and snap over the bracket upon application of inward pressure on the front face while the claws are pressed against the bracket, to thereby attach the cover to the bracket, with the bracket concealed from view behind the cover device. The front face may include an ornamental design. In another embodiment, the cover device includes a bottom tab for cooperating engagement with a removal tool.

An immersion device may include a surround configured for positioning before a user's eyes and having one of an electronic display and a station for receiving an electronic device with an electronic display. The electronic display may be configured for displaying a selected view of environmental footage relating to the surroundings of the user and simultaneously displaying virtual footage unrelated to the surroundings of the user.

In some embodiments, an apparatus comprises a housing, an emitter, and an electronic circuit. The housing is configured to fit within a patient's mouth. The emitter is at least partially encased within the housing. The emitter is configured to emit an effective amount of light to the alveolar soft tissue when the housing is disposed within the mouth. The electronic circuit is operatively coupled to the emitter. The electronic circuit is configured to control the emitter when the housing is disposed within the mouth and the apparatus is in use during orthodontic treatment. The apparatus and its use for regulating tooth movement or maintaining or improving oral tissue health are disclosed herein.

The invention is directed to a mouth piece for cooling of oral tissue of a patient during chemotherapy treatment. The mouth piece includes a cooling medium contained within the top element and the bottom element and able to retain a cooling environment within the mouth sufficient to reduce capillary blood flow to the patient's mouth. In one embodiment, an external chamber extends from the front of the mouth piece to house a cooling medium. A bladder is positioned inside the external chamber for storing a solution having a freezing temperature above the freezing point temperature of the cooling medium to assist in cooling the cooling medium.

Embodiments may include: receiving a facial image comprising a 2D depiction of a person's teeth at a first arrangement; receiving a tooth model comprising a 3D depiction of the person's teeth at a second arrangement; obtaining color information from the facial image, wherein the color information represents a color scheme of the person's teeth at the first arrangement; and generating a photo-realistic two-dimensional depiction of the person's teeth at the second arrangement using the 3D depiction of the person's teeth at the second arrangement and the color information obtained from the facial image.

Various operational mode arrangements of an electric toothbrush (10) include pre-programming a controller portion (16) of the electric toothbrush such that a single brushing event of approximately two minutes comprises automatically at least two different operating modes and specified times for each mode. Another operational mode includes the capability of operating the on/off button (20) of the toothbrush within a specified short time following termination of a normal brushing event to provide the user a specified additional time, e.g. 30 seconds of toothbrush action. A special toothbrush interface arrangement includes a display (80) which encourages children to maintain brushing for the full brushing period. This is accomplished through sequential illustration of the progress of an article from an initial state to a final desired state as the toothbrush is used for increasing portions of a full brushing time period. In another embodiment, a toothbrush (120) includes a capability of adjusting the performance/operating characteristics in accordance with the age of a child user.
