  • Patent number: 11627133
    Abstract: A method for providing access to a target electronic device through a first service running on a different electronic device may include receiving in the first service a command directed to the target electronic device from a command sender and receiving in the service device operation status parameters of the target electronic device. The device operation status parameters may include properties of the target electronic device such as a battery level, a battery charging rate, an age, a planned lifespan, a recent wireless usage, an internal temperature, or any of the above in relation to an intervening electronic device over which communication to the target electronic device travels, or any combination thereof. The method may also include using the device operation status parameters to determine, using the service, whether to provide or not to provide an update signal incorporating the command or information to the target electronic device.

  • Patent number: 9660948
    Abstract: Methods, devices, and machine-readable media are provided to perform rule-based rate limiting. As provided in this disclosure, this may include receiving a message en route to a destination, determining one or more parameters of the message, and determining whether the parameters of the message match parameters of a rule that specifies taking a first action when more than some number of messages having those parameters are received within a specific amount of time. When the one or more parameters of the message match the one or more parameters of the first restriction rule, a sliding window counter that indicates a total number of corresponding messages received within the amount of time may be incremented. When the first sliding window counter exceeds the first number of messages, the specified action may be taken.

  • Patent number: 9322296
    Abstract: A distributed compressed air storage system and method is described. A compression facility is configured to compress air and provides the compressed air to a pipeline. The pipeline is coupled to the compression facility and is configured to transport compressed air from the compression facility to a compressed air storage facility that is remote from the compression facility. A heat recovery unit is coupled to the compression facility and is configured to recover heat produced by compressing air in the compression facility. The compressed air storage facility is configured to store compressed air received from the pipeline and is located remote from the compression facility. An expansion facility is configured to receive compressed air from the compressed air storage facility and expand the compressed air to generate electricity.
