Abstract: A validation device in a communication network is configured to communicate control information bidirectionally via a control plane of the network and access message data via a production plane of the network. The validation device receives key data via the control plane, and accesses a message received via the production plane by a message receiving device. The message includes a signature derived from the first key data. The validation device uses the first key data to check validity of the signature.

Abstract: A headset with automatic noise reduction mode switching is provided to enable better call experience when conducting a call. The headset comprises at least one or more earphones, one or more microphones, a processor, and an active noise cancellation circuit, connected at least with the processor. The processor is configured to determine whether a call is being conducted using the headset, and if a call is being conducted, to switch the active noise cancellation circuit from a first ANC mode to a second ANC mode.

Abstract: A data validation system in a communication network has a bidirectional control plane and an independent message production plane. A sending device and a validation device communicate via the control plane and the production plane. A signer device and a validation device access message data from the sending device via the production plane. A computer-based network key manager conveys key data to the signer device and validation device via the control plane. The signer device accesses a message from the message sending device, produces a signature, and attaches the signature to the message. The validation device accesses the message received at the receiving device and uses the key data to validate the signature.

Abstract: A computer-based method includes transmitting a packet from a source across a packet-switched network that includes multiple network switches, and attaching, or otherwise associating, a unique signature to the packet at one or more of the network switches. Each unique signature identifies a corresponding one of the network switches, through which the packet passes as it travels from the source toward a destination. The packet and an attached, or otherwise associated, string of signatures from the plurality of network switches, is received at or near the destination in the packet-switched network. In a typical implementation, the validity of the packet is checked, by a validator (e.g., at or near the destination).

Abstract: A device implementing an adaptive positioning system may include at least one processor that is configured to concurrently implement a first positioning system that generates first positioning information items and a second positioning system that generates second positioning information items. The processor may be configured to buffer the second positioning information items generated by the second positioning system and to determine a position estimation for the device based on the first positioning information items generated by the first positioning system. The processor may be configured to detect a degradation in a quality of the first positioning system. The processor may be configured to, in response to detecting the degradation in the quality of the first positioning system, determine the position estimation for the device based at least in part on at least one of the buffered second positioning information items generated by the second positioning system.

Abstract: A clamping device is disclosed for coupling peripheral flanges of a pair of tubular members together. The clamping device has a retaining member for coupling the peripheral flanges of the tubular member together, with first and second coupling ends being releasably coupled together by a latch assembly from an open position to a closed position. The latch assembly has a connecting member with a pivoting end and an anchoring end. The pivoting end of the connecting member is pivotally coupled to the first coupling end about a pivot axis between an unengaged position where the anchoring end is spaced from the second coupling end and an engaged position where the anchoring end is removably coupled to the second coupling end. The latch assembly further has a retention member coupled to the pivoting end of the connecting member for retaining the connecting member to the first coupling end.
