  • Publication number: 20150268725
    Abstract: Systems and methods for force-based object manipulation and haptic sensations are disclosed. One disclosed method includes the steps of receiving a first signal indicating a location of a user interaction and receiving a second signal indicating a first force. The method also includes, if the location of the user interaction corresponds to an object displayed on a display screen: outputting a first haptic signal to a haptic output device to cause a first haptic effect; and outputting a second haptic signal to the haptic output device to cause a second haptic effect if the first force meets or exceeds a first force threshold.

  • Publication number: 20140368323
    Abstract: A system is provided that converts an input, such as audio data, into one or more haptic effects. The system applies a granular synthesis algorithm to the input in order to generate a haptic signal. The system subsequently outputs the one or more haptic effects based on the generated haptic signal. The system can also shift a frequency of the input, and also filter the input, before the system applies the granular synthesis algorithm to the input.

  • Publication number: 20080250500
    Abstract: Detection of a man-in-the-middle attack. In particular implementations, a method includes detecting a first event comprising notification of an invalid wireless management frame operable to cause a termination of a connection between a wireless client and a wireless access point, wherein the notification is based on a failed verification of a management integrity code (MIC) appended to the wireless management frame. The method also includes detecting a second event involving notification of either an authentication failure associated with the wireless client or a connection between the wireless client and a rogue access point. The method also includes performing one or more actions upon detection of the first event and the second event within a threshold period of time of each other.
