Abstract: Systems and methods for generating a master video stream from at least two live video streams are provided in this disclosure. The systems include a combination component that combines the live video streams to generate the master video stream. In one aspect, the live video streams can be copies of the same recording that are multicast from different locations according to User Datagram Protocol. The live video streams suffer different errors, such as stream corruption or stream error, due to the transmission. The combination component eliminates the errors in the live video streams due to transmission and creates a substantially error-free master video stream.

Abstract: A computer generates one or more geometric rays at a predetermined height above one or more portions of an avatar's body in a virtual environment. Once the rays are generated, the computer computes intersections of the one or more rays with a collision mesh that defines a terrain of the virtual environment at the location of the avatar. Then, the computer computes the point of intersection of each of the one or more rays with the collision mesh. Using the points of intersection, the computer calculates an offset in an elevation and/or an offset in an orientation of the avatar with respect to the terrain in the virtual environment. Further, the computer adjusts the elevation and/or the orientation of the avatar based on the calculated offset in the elevation and/or the elevation in the orientation, respectively, such that the adjusted elevation and/or orientation compensates for the calculated offsets.

Abstract: A computer determines a modified location for an avatar of a first entity in a virtual environment based on a location of the first entity in a capture volume and a transformation used to map a second entity from the capture volume to the virtual environment. The modified location of the avatar of the first entity relative to a location of an avatar of the second entity is consistent with the location of the first entity relative to the location of the second entity in the capture volume. Once the modified location is determined, the computer displays a graphical cue corresponding to the first entity at the modified location of the avatar of the first entity provided that a distance between the modified location of the avatar of the first entity is different from a current location of the avatar of the first entity in the virtual environment.

Abstract: A motion capture simulation system can include a capture volume. A participant disposed in the capture volume can be motion captured and immersed into a virtual environment. The virtual environment may be larger in size than the capture volume. In the virtual environment, the participant may be represented by an avatar. The avatar in the virtual environment can be moved in a first direction based on a motion of the participant in the first direction in the capture volume. As the participant moves in the first direction in the capture volume, the participant may approach a boundary of the capture volume, while the participant's avatar may have space to move further in the first direction in the larger virtual environment. Approaching the boundary, the participant can change direction, for example turning around to avoid the boundary. The redirected participant can continue driving the avatar to move in the first direction.

Abstract: A system and method for processing multicast streams is disclosed. A router receives the multicast streams and communicates the streams via communication tunnels to a set of ingestion pipelines. Each communication tunnel can be terminated upon the ingestion pipeline receiving a multicast stream. The set of ingestion pipelines process and deliver the multicast streams across existing IP infrastructure for real time distribution.

Abstract: A system and method of executing a firearm transaction is presented. Customer information entered into a first form is received from a user terminal. The customer information is stored in a database and associated with a serial number. When an identity of the customer is authenticated at a location of the vendor, information describing the vendor and a firearm entered into a second form is received from a vendor terminal. The information describing the vendor and the firearm is stored in the database and associated with the serial number. A background check request is transmitted to a governmental agency. The background check includes at least a portion of the customer information. When the background check indicates that the transaction may proceed, at least a portion of the customer information, the vendor information, and the firearm information is transmitted to a point of sale system.

Abstract: There is disclosed a building energy system comprising a building enclosure having an insulated building envelope that incorporates at least one perimeter fenestration assembly, and an integrated mechanical system that provides heating and cooling. The integrated mechanical system comprises a cold thermal storage tank, a hot thermal storage tank, and a heat pump that transfers heat from the cold thermal storage tank to the hot thermal storage tank.

Abstract: The present invention is a football counting device that utilizes a microcomputer so that a proper count can be given for backyard or sandlot football games as to when the defense can rush the passer. A push-button switch will start the sequence and the microcomputer (1) controls an audio sound that counts “1 Mississippi”, “2 Mississippi” and (2) gives a visual display as to when the quarterback can be rushed. The length of time delay and the voice utilized can be selected by the players. The sequence repeats for each new down.

Abstract: A framed panel and related method of manufacture are disclosed. A framed panel unit includes a panel along the edge of which thermoplastic frame members are disposed. The frame members have first and second opposed side walls which define a channel for receiving the edge of the panel. The channel of each frame member has spacers between the panel and each side wall for spacing the panel from the side walls. Prior to welding together the ends of the frame members, the spacers retain the frame members on the panel. The panel may include multiple opposed sheet members with a spacer between the sheet members spacing them apart, and a reactive thermoplastic sealant material bonding the sheets to the frame members. An associated method of forming a named panel, frame members for a panel, and a spacer component for use in mounting a panel within a channel of a frame member are also disclosed.
