| 20100147053 | BREAKAWAY TOOLING APPARATUS - A breakaway tooling apparatus connectable to a manipulator and at least one tool for limiting the amount of damage to the associated manipulator and tool when the apparatus accidentally engages an obstacle. The detection mount has a narrowed neck region and stepped throughbore adjacent the narrowed neck region for creating a weakened portion that will fracture upon the realization of a predetermined force to the detection mount. An air passageway extends from an outer portion of the detection mount to an inner portion of the detection mount, wherein the air passageway is connectable to a supply of pressurized air. A blocking member prevents the pressurized air from passing through the air passageway in the detection mount when the detection mount is not fractured at the weakened portion, and the blocking member allows pressurized air to flow through the air passageway in the detection mount when the detection mount is fractured at the weakened portion. A pressure indicator determines whether the air pressure in the air passageway is above or below a predetermined air pressure level, thereby indicating whether the detection mount is fractured at the weakened portion. | 06-17-2010 |

| 20080235509 | METHOD FOR EXCHANGING MESSAGES AND VERIFYING THE AUTHENTICITY OF THE MESSAGES IN AN AD HOC NETWORK - A method for exchanging messages containing reliable information between nodes in an ad hoc network, such as a vehicle ad hoc network. The method includes the steps of providing a public key for a PKI encrypted certificate authority signature to all nodes known to transmit reliable information. Each node transmits a signal containing node identification information and the PKI encrypted certificate authority signature associated with that node. Each node also receives like signals from other nodes and then decrypts the certificate authority signatures from the received signals by using the certificate authority public key to ascertain the authenticity of the received certificate authority signatures and the reliability of the received message. Thereafter, the nodes receive and accept messages with a TESLA encrypted signature only with nodes identified to have authentic certificate authority signatures until the occurrence of a subsequent predefined event, such as a new node in the network or the elapse of a predetermined time period. | 09-25-2008 |
| 20090028354 | Echo Canceller Employing Dual-H Architecture Having Split Adaptive Gain Settings - An echo canceller circuit is set forth. The echo canceller circuit includes a digital filter having adaptive tap coefficients to simulate an echo response occurring during a call. The adaptive tap coefficients are updated during the call using a Means Squares process. A tap energy detector is also employed. The tap energy detector identifies and divides groups of taps having high energy from groups of taps having low energy. The high energy tap groups are smaller in number than the low energy tap groups. The high energy tap groups are adapted separately from the low energy tap groups using the Least Squares process. Still further, the high energy tap groups may be adapted using an adaptive gain constant a while the low energy tap groups are adapted using an adaptive gain constant a′, wherein a>a′. | 01-29-2009 |
| 20090138196 | SYSTEM AND METHOD OF VEHICULAR WIRELESS COMMUNICATION USING AN INTEGRATED COORDINATING ACCESS POINT - A system and method of vehicular wireless communication over a Dedicated Short Range Communication service band is provided. The system includes a vehicle having a navigation means, a processor, and a communication means for transmitting a message via a wireless communications link. The system includes a control channel for communicating a safety communication and a service channel for communicating a non-safety communication. The control channel is subdivided into a contention-free period having a group management interval, a service announcement interval and a safety exchange interval and a contention period having a non-safety service interval. The system further includes an integrated coordinating access point that operates in both the control channel and service channel. The method includes the steps of determining if the vehicle is within communications range of the region, determining if the vehicle is registered with the access point, and if the vehicle is within the communications range of integrated coordinating access point, determining if a current time is within the safety exchange interval, and transmitting the safety communication by each registered vehicle during the safety exchange interval at the predetermined time for each registered vehicle. The method further includes the steps of determining if the safety communication exchange by every registered vehicle is completed, and permitting the vehicle to leave the control channel if the safety communication exchange is complete, and determining if a current time is within a contention period, and transmitting the non-safety communication if the current time is within the contention period. | 05-28-2009 |
| 20090138197 | System And Method Of Vehicular Wireless Communication Using A Group Manager - A system and method of vehicular wireless communication over a Dedicated Short Range Communication service band is provided. The system includes a vehicle having a navigation means, a processor, and a communication means for transmitting a message via a wireless communications link. The system includes a control channel for communicating a safety message and a service channel for communicating a non-safety message. The control channel is subdivided into a contention-free period having a safety exchange interval and a contention period having a non-safety service interval. The system further includes a dedicated group manager that partitions the vehicles into groups. The method includes the steps of determining if the vehicle is within communications range of the region, determining if the vehicle is registered with the group manager, if the vehicle is within the communications range of the group manager, determining if a current time is within the safety exchange interval, and transmitting the safety communication by each registered vehicle during the safety exchange interval at the predetermined time for each registered vehicle.
