Abstract: A customer initiated password reset system resets user passwords on a variety of network entities, such as internal systems, allowing simultaneous reset with a minimum number of user specified passwords that nonetheless satisfy the password specifications of these internal systems. Thereby, the user avoids the tedium of logging into each of these systems, changing their password, logging out, etc., for each system with the likelihood of creating unique passwords for each system that have to be remembered. By further incorporating a score metric based upon how many character sets are touched, a required degree of complexity can be measured and enforced against the password specifications. Advantageously, a table-based approach to enforcing password reset against the multiple password specifications facilitates making and fielding updates.

Abstract: Described is an airborne monitoring station (“AMS”) for use in monitoring a coverage area and/or unmanned aerial vehicles (“UAVs”) positioned within a coverage area of the AMS. For example, the AMS may be an airship that remains at a high altitude (e.g., 45,000 feet) that monitors a coverage area that is within a line-of-sight of the AMS. As UAVs enter, navigate within and exit the coverage area, the AMS may wirelessly communicate with the UAVs, facilitate communication between the UAVs and one or more remote computing resources, and/or monitor a position of the UAVs.

Abstract: An unmanned vehicle determines how to perform a task based at least in part on a message received from another unmanned vehicle. At a later time, the unmanned vehicle detects that the other unmanned vehicle has become untrusted. The unmanned vehicle recalculates how to perform the task such that the recalculation is independent of any messages from the other unmanned vehicle. The unmanned vehicle may also transmit messages to other unmanned vehicles to provide notification of untrustworthiness of the other unmanned vehicle.

In some examples, the recognition is performed on the user device. In other examples, the utterance and associated context information are sent over a network to a recognition computing device that performs the recognition.

Abstract: Techniques are described for employing precomputed results of applying rules to content items, the rules applicable to determine whether content items may be electronically published. On receiving a request for a content item, rules applicable to the content item may be identified.

If the datastore includes a current result, the current result may be employed in determine whether the content item may be presented. If the datastore includes a previous result, the previous result may be so employed. If the datastore includes a previous result or no appropriate result, a job may be queued to calculate the current result asynchronously relative to the request for the content item.
