  • Patent number: 9767445
    Abstract: Techniques, including systems and methods, for virtual resource cost tracking account for unused capacity of implementation resources that are dedicated to particular customers and, as a result, are unusable for maintaining virtual resources for other customers. Customers requesting dedicated use of implementation resources are charged in a manner that compensates the virtual resource provider for the lost ability to use unused capacity of implementation resources to serve other customers. Customer charges may be determined by a pricing function that is calculated such that, for a base of customers, expected revenue from the base of customers approximates a revenue goal. The revenue goal may be determined based on revenue that would have been expected had the unused capacity of the dedicated implementation resources been available for serving other customers.

The changing, calibrating, and reducing are responsive to visual cues that describe acoustic characteristics of a location of a device that includes the acoustic echo canceller. Such visual cues may indicate that no human being is present at the location, that some subject(s) are engaged in speaking or sound generating activities, or that motion associated with an echo path change has occurred at the location.

  • Patent number: 9769153
    Abstract: A customer can demonstrate control over an element, such as a domain, by receiving a certificate from a certificate authority. A customer can submit a request and receive a request token. The customer can generate a cryptographic hash of the request using the token, which a service provider can compare against an expected hash similarly generated. If the hashes match, an action can be taken such as a certificate issued. A customer can request one or more request tokens up front, whereby the tokens can be used to submit hashes with requests at the appropriate time. In some embodiments a customer can submit a request specifying one or more domains, and a service provider can provide a list of confirmatory email addresses from which the customer can select. The service provider can then send a message to that address that include a link for requesting a certificate.

  • Patent number: 9769767
    Abstract: Interference on a first wireless radio caused by operation of a second wireless radio in the same device may be reduced by reducing the transmission power of the second wireless radio. Signal strength data associated with the first wireless radio and isolation values associated with antennae used by the second wireless radio may be used to determine a target change in transmission power of the second wireless radio that would eliminate interference with the first wireless radio. Signal strength data associated with the second wireless radio and threshold data indicative of minimum signal strengths to maintain a threshold level of quality for the second wireless radio may be used to determine a maximum change in transmission power. The transmission power of the second wireless radio may be reduced by the lesser of the target amount or maximum amount.
