Abstract: A device to detect hot-plugging and hot-unplugging of hard disk and the hard disk type includes a connector and a control circuit. When hot-plugged, the hard disk is coupled to the connector, the control circuit comprises delay circuit and latch circuit. The delay circuit delays a falling edge of the third signal and outputs a delay signal, the latch circuit processes the first and second signals and outputs a logical result as a latch signal. The control circuit determines the connected or disconnected status and type of the hard disk according to the respective levels of the first and second signals, the delay signal, and the latch signal. The delay signal and the latch signal work to correct error of the control circuit in determining connectivity and non-connectivity during a session due to asynchronous changes in signal levels of the first and second signals.

Abstract: A device and method providing audio-based, continuous authentication of a user to provide access to a processing device. A user echoprint model is created while a user interacts with an authentication interface for another authentication method of the device, transparently to the user. The sound waves are user-specific and inaudible. The user-specific sounds are reflected by the user and used to construct an echoprint which can be compared by a previously constructed user-specific, echoprint model. If the result is positive, access to the processing device may be allowed. Access to the processing device is based on the audio authentication or the alternative authentication is based on the result of audio authentication and updates a device state indicating whether the display is on or off and whether the device is locked or unlocked.

Abstract: This application relates to a model training method.
