  • Patent number: 10896432
    Abstract: A network metering service obtains from a data store raw metering data specifying network bandwidth utilization for a plurality of customers. The network metering service aggregates this data in order to identify bandwidth usage for each service of a computing resource service provider and for each customer. Based on this data, the network metering service determines a peak-to-average score and a correlation coefficient for each customer, which may be used to determine a unit cost burden. The network metering service may utilize the unit cost burden for each customer to determine whether the customer should be provided with a discounted rate for network bandwidth usage or should incur a price increase.

  • Patent number: 8444452
    Abstract: A method, system, and medium are provided for a wireless musical figurine belonging to a set of wireless musical figurines that play audio files in coordination with one another. One system of the musical figurine includes a wireless transceiver utilized to communicate with one or more musical figurines. The musical figurine also includes a set of master audio files of a first quality level, and a set of slave audio files of a second quality level. An audio player plays an audio file from the set of master audio files or the set of slave audio files. A master audio file is played when the musical figurine is initiated in accordance with a user indication, and a slave audio file is played when the musical figurine is initiated by another musical figurine. The musical figurine may also have movement capabilities which may be coordinated with the playing of an audio file to present a dancing figurine.

  • Publication number: 20110032225
    Abstract: Decoration devices of various forms are disclosed, including decoration devices that connect with one or more decorative bodies having performances or routines. When decorative bodies are attached to decoration devices of various embodiments of the present invention, the activation and control of any performance or routine on one decoration device may result in the activation and control of any number of performances or routines on other decoration devices. Once a selection of a performance or routine is received or identified, information associated with the selection may be communicated among the decorative bodies and used to activate additional performances.

  • Patent number: 7856495
    Abstract: Techniques are disclosed for identifying the locations of equipment in computing environments such as data centers. For example, a method of identifying a plurality of computing devices in a computing environment includes the following steps. A first temperature-indicative map of the plurality of computing devices is generated while the plurality of computing device is in a first mode. The first temperature-indicative map is overlaid with a facility map associated with the computing environment. A first one of the plurality of computing devices is placed into a second mode. The second temperature-indicative map of the plurality of computing devices is generated while the first one of the plurality of computing devices is in the second mode and the remainder of the plurality of computing devices is in the first mode. The second temperature-indicative map is overlaid with the facility map associated with the computing environment.

  • Patent number: 7361058
    Abstract: A universal adapter enables amusement object connectors to be reliably and securely coupled with power cord receptacles of varying sizes. The adapter includes a body providing first and second end sections and conductive contact structure extending between the end sections, as well as one or more cantilevered locking arms. The first end section may be adapted for receiving a base plug of an object providing amusement effects, or may be formed as the base plug itself. The second end section is adapted to be received within the receptacle of a power cord, such that electrical contacts of the base plug and the receptacle may be electrically connected with one another through the conductive contact structure of the adapter. Each locking arm releasably engages with an outer surface of the power cord receptacle to provide a more secure connection between the adapter and the power cord receptacle.

  • Patent number: 6937422
    Abstract: An apparatus and method of controlling an actuator of a data storage device detect and/or correct narrowband mechanical excitations such as due to spindle bearing defects through sensing and/or rejecting disturbance frequencies associated with such narrowband mechanical excitations in an actuator control signal generated by a data storage device controller. A narrowband filter may be used to reject, from an actuator control signal generated by a data storage device controller, a disturbance frequency associated with a spindle bearing defect in a data storage device, and disposed in proximity to a zero crossover frequency associated with the data storage device controller. In addition, a peak filter disposed in a control loop of a data storage device controller may be configured to detect a spindle bearing defect in a data storage device by detecting an amplitude of a control signal in the control loop in proximity to a disturbance frequency associated with the spindle bearing defect.
