  • Patent number: 9058080
    Abstract: Detection of degradation of a user input device may allow for notifying a user of an impending failure of the user input device so that the device may be taken out of service or repaired. A method for detecting degradation of a user input device may carry out one or more operations including, but not necessarily limited to: determining that a portion of the user input device is degraded based on two or more received signals of the user input device, the two or more received signals being indicative of one or more user inputs; and providing a user notification indicative of a degradation of the user input device in response to determining that a portion of the user input device is degraded based on two or more received signals of the user input device.
    Type: Grant

  • Patent number: 8612808
    Abstract: Detection of degradation of a touch-based user input device may allow for notifying a user of an impending failure of the touch-sensitive user input device so that the device may be taken out of service or repaired. Systems for detecting degradation of a touch-based user input device may carry out one or more operations including, but not limited to: determining that a signal indicative of a user touch is erroneous; providing a user notification indicative of a degradation of the touch-based user input device in response to determining that a signal indicative of a user touch is erroneous.

  • Patent number: 8515967
    Abstract: Various embodiments for efficiently provisioning a storage area network (SAN) are provided. In one embodiment, SAN information is provided to an engine for optimization. The SAN information includes at least one of SAN configuration information, SAN usage information, at least one cost profile, and at least one chargeback model. Based on the SAN information, those of an available plurality of storage resources not meeting at least one storage criterion are filtered. The filtered storage resources are ranked on a cost basis. A resource configuration graph is constructed based on the ranked storage resources. The resource configuration graph is traversed to obtain a plurality of possible SAN configuration plans. At least one power profile is applied to the plurality of possible SAN configuration plans to rank the plurality of possible SAN configuration plans by energy consumption.
