International Classification:

H04K 1/00
H04L 9/00

US Classification:

380 33, 380270, 713150, 713168

Abstract:

A method for establishing a secondary communication channel between at least two computing devices over a network medium through use of a primary channel connects a first computing device with a first telephonic unit and a second computing device with a second telephonic unit. If the two telephonic units are in communication with each other over a primary channel, and communication channels are established between the computing devices and their respective telephonic units, then the first computing device transmits its location information to the second computing device over the primary channel. A connection is then established between the second computing device and the first computing device over a secondary communication channel.

International Classification:

H04L 9/32

US Classification:

713169, 713165, 713170

Abstract:

A system and method for sharing files securely includes server software on a first device configured to communicate with server software operating on one or more other preauthorized devices, such as a second device. The servers communicate with each other securely using cryptographic information exchanged during a preauthorization phase using a range-limited communication channel. The server on the first device obtains file information from the other preauthorized device(s) and combines the information with local file information from the first device. This combined file information is sent to client software operating on the machine, which presents the combined file information to users.

G09G 5/00

US Classification:

382275, 345178

Abstract:

In accordance with one aspect of the present exemplary embodiments, a calibration arrangement is configured to assist in calibration of a surface scanning system where the calibration arrangement includes a preconfigured physical object which may embody dimensional information wherein the dimensional information is used to calibrate a surface of the scanning system. In an alternative embodiment, the preconfigured physical object is configured to obtain data for use in calibration of the surface of a pan/tilt surface scanning system.

US Classification:

380277000, 713163000, 713201000

Abstract:

A location-limited channel is implemented using physical exchanges of physical tokens. The physical tokens are implemented using writeable or re-writeable storage media. Location-limited channels, when used to implement pre-authentication protocols, provide demonstrative identification and authenticity. A group originator loads pre-authentication information and a network location from a communication device onto the location-limited physical token channel. The location-limited physical token channel is passed to another participant, who copies the originator's pre-authentication information and location onto that participant's communication device. That participant then adds that participant's own pre-authentication information and network location onto the location-limited physical token channel. This is repeated until the last participant passes the location-limited physical token channel back to the group originator. The originator thus has pre-authentication information and network locations for all other participants. The originator establishes secure communications with each participant based on the originator' and that participant's shared information.
