Abstract: A vehicle computer comprises a processor and a memory. The memory stores instructions executable by the processor to receive a location of a first stationary directional short-wave antenna, to determine a line from a vehicle location to the location of the first stationary antenna, to transmit a short-wave request message to the first stationary short-wave antenna based on the determined line, the message including vehicle data, and upon receiving a short-wave acknowledgment message from the first stationary short-wave antenna, to transmit a second short-wave message including vehicle data.

Abstract: Broadcast signatures (fingerprints) from different sources are compared to distinguish between a known base media item and unknown versions of the known base media item, without prior storage of the unknown altered versions of the known base media item. Field recorders collect and store in buffers signatures found within portions of sequential broadcast content. Mobile devices (users) collect unknown signatures while recording broadcast content. Using a cloud callout routine, the mobile device requests a comparison between the collected unknown signatures and the field recorded signatures. Potential matches can be loose matches, strict matches or comparisons between failed loose comparisons.

Abstract: A location of an unmanned aerial vehicle (UAV) is collected while the UAV is flying along a flight path. A communication signal distribution in a proximity of the location is determined. One or more relay locations for arranging one or more relays are determined based on the communication signal distribution to improve communication coverage along the flight path. An identification of the UAV is transmitted to an authentication center for authentication, without using the one or more relays, in response to determining, based on the communication signal distribution, that the UAV is capable of directly communicating with the authentication center or a communication network associated with the authentication center above a quality threshold.

Abstract: In various examples, radio frequency conducted power of a device—such as a human interface device (HID)—may be adjusted to account for various operating conditions. For example, when a user holds the device in their hand, the radiated power level of the device may be reduced to a level that reduces transmission performance of the device. To account for this, one or more detection mechanisms may be used to determine whether the device is held in hand and, when determined to be held in hand, the radio frequency conducted power of the device may be increased—while complying with regulatory requirements governing wireless transmissions—to increase the performance of the device. When not held in hand, the radio frequency conducted power may be less, thereby resulting in consistent performance of the device under varying operating conditions.

Abstract: A dynamic specific absorption rate (SAR) may be implemented by monitoring and controlling power utilization of the various radio frequency (RF) emitting components over time within a mobile device. Power utilization may be tracked and modified to control the time-averaged RF exposure over a rolling time window. Periodically calculations of the updated rolling averages for RF transmissions may be performed based on the transmission data received from the mobile device components, and the continuously updated rolling averages of RF transmissions may be compared to time-average power utilization limits. Based on such comparisons, the mobile device may dynamically adjust the current transmissions of the radio transceivers and other RF emitting components on the mobile device.
