Piggybacking unmanned aerial vehicle

Abstract: Various embodiments include methods for piggybacking an unmanned aerial vehicle (UAV) on a vehicle (e.g., motor vehicles and trailers coupled to motor vehicles) to reach a destination. Various embodiments may include determining whether to dock on a vehicle. One or more candidate vehicles may be identified for docking. Travel profile characteristics of the one or more candidate vehicles may be identified. A first vehicle may be selected from the one or more candidate vehicles based on one or more travel profile characteristics that assist the UAV in reaching the UAV destination. The UAV may dock with the first vehicle. While docked to the first vehicle the UAV may charge an onboard battery via an electrical connection in a docking structure or by harvesting energy in the wind caused by movement of the vehicle by configuring the UAV rotors to charge the battery.

Mobile Commerce Authentication And Authorization Systems

Abstract: Mobile commerce authentication and authorization systems enable currently existing point-of-sale devices that are neither structurally nor systemically altered to conduct financial transactions with a customer using an access terminal across a wireless communications system. The point-of-sale devices receive an input from a payment instrument replacement, which identifies the transaction to the point-of-sale device as a transaction including an access terminal. Authentication of the user of the access terminal is achieved at least by application of position and/or location determinable features of the access terminal, the position and/or location of a point-of-sale device of a vendor or merchant where the customer seeks to purchase goods or services, and the payment sum entered on the point-of-sale device. A payment matching server may assist in processing the location data and the payment sum amount across communications network.

Signaling microphone covering to the user

Abstract: A mechanism is provided that monitors secondary microphone signals, in a multi-microphone mobile device, to warn the user if one or more secondary microphones are covered while the mobile device is in use. In one example, smoothly averaged power estimates of the secondary microphones may be computed and compared against the noise floor estimate of a primary microphone. Microphone covering detection may be made by comparing the secondary microphone smooth power estimates to the noise floor estimate for the primary microphone. In another example, the noise floor estimates for the primary and secondary microphone signals may be compared to the difference in the sensitivity of the first and second microphones to determine if the secondary microphone is covered. Once detection is made, a warning signal may be generated and issued to the user.

Communique system for virtual private narrowcasts in cellular communication networks

Abstract: The communique system for private virtual narrowcasts operates with existing cellular communication networks to provide private virtual narrowcast communication services, that are initiated by a narrowcast host, to subscribers. The Communique can be unidirectional (broadcast) or bi-directional (interactive) in nature and the extent of the Communique is narrowcast, where cells and/or cell sectors are grouped to cover a predetermined geographic area or demographic population or subscriber interest group to transmit information to a private group of subscribers who populate the target audience for the narrowcast transmissions. The grouping of cells to form the communique coverage area for the narrowcast transmissions need not be contiguous. The private virtual narrowcasts use the code, frequency and time domains to enable multiple users to share the same wireless resource in a manner that, from the users perspective, has dedicated spectrum or channel capacity to their particular application.

Scalable downmix design with feedback for object-based surround codec

Abstract: In general, techniques are described for grouping audio objects into clusters. In some examples, a device for audio signal processing comprises a cluster analysis module configured to group, based on spatial information for each of N audio objects, a plurality of audio objects that includes the N audio objects into L clusters, where L is less than N, wherein the cluster analysis module is configured to receive information from at least one of a transmission channel, a decoder, and a renderer, and wherein a maximum value for L is based on the information received. The device also comprises a downmix module configured to mix the plurality of audio objects into L audio streams, and a metadata downmix module configured to produce, based on the spatial information and the grouping, metadata that indicates spatial information for each of the L audio streams.
