Abstract: Systems and methods are described to render a Live Avatar View third-person view as an overlay of a first person Spectator View, as mirrored from a Virtual Reality headset, in a Dual Perspective View. In some embodiments, a clinician tablet may display Dual Perspective View with a full screen Spectator View, to maximize visibility, and render a translucent avatar from Live Avatar View (LAV) to overlay the Spectator View for simultaneous visibility during a therapy session. Spectator View may be critical to monitor for therapy guidance and an LAV conveys valuable movement and safety data. A translucent avatar overlay and activity cues allows monitoring the avatar from Live Avatar View in a way that would not block the Spectator View or occlude other body parts potentially hidden.

Abstract: A hole-saw comprises a tubular body connectable at one end to inter alia a power drill and formed at its other end with an annular array of cutting teeth. A collar is positioned at the end of the tubular body remote from the cutting teeth, the perimeter of the collar extending generally normal to and beyond the perimeter of the tubular body.

Abstract: A trailer hitch coupler to couple a trailer to a trailer hitch includes a socket adapted for receiving a trailer hitch ball; a clamp associated with the socket and operable for engaging the trailer hitch ball; a sensor operatively connected with the socket and operable for determining a distance between an inner surface of the socket and an outer face of the trailer hitch ball when the trailer hitch ball is positioned within the socket; a clamp prevention device operatively connected with the socket and with the clamp and operable to prevent engagement of the clamp with the trailer hitch ball; and a release mechanism operatively connected with the sensor and the clamp prevention device and operable to release the clamp prevention device to allow the clamp to engage the trailer hitch ball when the sensor communicates a desired hitch condition.

Abstract: A device for enhancing the posture of a seated person using a personal viewing item can be placed on and supported by at least a portion of the user's lap or some other support surface, such as a table. The posture enhancement device can facilitate or otherwise force the user in positioning his hands at or above the level of the sternum. As a result, the user's head is kept up and in line with his hands and/or the personal viewing item held in the user's hands. As a result, the user's spine is kept in a neutral position, and the seated user achieves a more ergonomically correct posture when using a personal viewing item. A downward angle of the head is avoided, thereby minimizing future long term health issues that can develop from prolonged periods in such an incorrect posture.

Abstract: A system that multiplexes a plurality of wireless devices with a wireless network, each of the wireless devices bring a common telephone number. The system assigns a predefined access time for each of said wireless devices. The system also assigns a predefined length of time during which each of said wireless devices will have access to said wireless network. A sequence of accesses to the wireless network can then be initiated in accordance with the predefined access time and the predefined length of time such that a maximum of one of the wireless devices accesses said local network at a tine.

Abstract: A plurality of linked gaming machines are disclosed that enhance the community participation and enjoyment of a game on multiple gaming machines. Players participate in an interactive game, either simultaneously, alternatively or in a systematic sequence, as a group or community. The participating players compete in the game such that the actions and results of each player affect the other players in the community. The interactive game combines skill and luck to improve play of the game. The interactive game could be a bonus game which players need to qualify in order to participate. If a player does not qualify, a wager can be placed to participate in the game. Players with different wagers can participate in the same game and players can wager on the outcomes of other players.
