  • Patent number: 9652663
    Abstract: Exemplary methods, apparatus, and systems are disclosed for authenticating a user to computing device. In one exemplary embodiment, an indication of a request by a user to unlock a mobile device in a locked state is received. One or more images of the face of the user are captured. Facial components of the user from the one or more captured images are extracted. A determination is made as to whether the user is an authorized user or a non-authorized user based at least in part on a comparison of the facial components of the user extracted from the one or more captured images to facial components of the authorized user from one or more authentication images of the authorized stored on the mobile device. If the user is determined to be the authorized user, the mobile device unlocked; otherwise, the mobile device is maintained in its locked state.

  • Patent number: 9544442
    Abstract: Presented herein are techniques to reduce error probability and eliminate the lingering signal that causes problems during audio signal data transmission. An electroacoustic transducer of a first electronic device receives a data encoded audio signal that includes modulated digital data therein. The data encoded audio signal is demodulated to produce a present input signal that includes a target frequency and a lingering effect of a previously received data encoded audio signal. Lingering cancellation is performed on the present input signal to produce a present output signal from which the lingering effect of the previously received data encoded audio signal has been removed.

  • Publication number: 20160313927
    Abstract: A method for dynamically storing data of translation layer in a solid state disk is provided. A data access instruction is sent by a host. Whether the access data is a hot data or a cold data is determined. Whether a flash translation layer (FTL) dynamically established by the SSD is in the partial mapping method is checked. Access rates of different storage medium are compared. The storage position of the hot data of the FTL is adjusted to the storage medium having a faster access rate and the storage position of the cold data of the FTL is adjusted to the storage medium having a slower access rate to increase the access rate.
