  • Patent number: 11295758
    Abstract: Devices and methods are disclosed for trusted listening. In some examples, an apparatus can include an audio receiving device having a microphone configured to capture sound and produce an audio signal, a processing unit configured to add a trusted signature to the audio signal, and an output configured to provide the audio signal. Further, a method of trusted listening can receive a first audio signal representing a real-time sound, generate a trusted signature in an audible format, and produce a second audio signal including the trusted signature.

  • Publication number: 20210273795
    Abstract: Systems and methods are disclosed for trusted imaging. In some examples, a trusted imaging device can emit a patterned light onto a real-world scene while an image sensor (e.g. photo or video) generates data representative of the real-world scene. The data can be processed to attempt to recover a pattern of the patterned light from the data. Whether, or to what extent, the pattern can be recovered can be determinative of a trustworthiness of the data from the image sensor. In further examples, the image data can be encrypted, as well as the imaging device output. In still further examples, a depth map of the image data can also be used to determine the trustworthiness of the image data.

  • Patent number: 8013552
    Abstract: Various systems and methods for controlling DC motors are disclosed herein. For example, one method provides for controlling a polyphase, brushless DC motor. The method includes providing a DC motor that has a plurality of phases. Such a DC motor operates by inducing a current in the plurality of phases in accordance with a plurality of commutation states. In the example, six commutation states are discussed, but fewer than or more than six commutation states may exist. The method further includes initializing a count, inducing a current in the plurality of phases in accordance with a first commutation state, and incrementing the count until the current achieves a threshold in the first commutation state. Then, a current is induced in the plurality of phases in accordance with a second commutation state, and the count is decremented until the current achieves the threshold in the second commutation state.

  • Patent number: 7145742
    Abstract: A control apparatus controls retraction of a device carried on a moveable member actuated by an electric motor after a sudden power loss. The control apparatus includes a measuring circuit for measuring a back electromotive force (back EMF) from the electric motor during a measuring phase. The control apparatus also includes a controller which receives the actual velocity and provides a command signal for controlling a magnitude of the drive current based on a commanded velocity and the actual velocity of the moveable member. The control apparatus further comprises a current control loop for providing a command current signal based on the current provided to the electric motor and the command signal, and for providing the electric motor with the drive current during a driving phase based on the command current signal.

  • Patent number: 7068460
    Abstract: A disk drive emergency retract architecture for providing power to a voice coil motor (VCM) to retract a transducing head from a surface of a recordable medium during loss of power from an external power supply. The disk drive emergency retract architecture comprises a spindle motor, having an internal inductance and an internal resistance, for spinning the recordable medium. The spinning recordable medium creates a back electromotive force (BEMF) in the spindle motor. A boost circuit transfers the back electromotive force located in the spindle motor to a capacitor which stores and supplies power to the VCM. The capacitor is connected to a power switch circuit, which supplies power from the capacitor to the VCM when the power switch circuit is in a conducting state and prevents power from being supplied to by the capacitor to the VCM when the power switch circuit is in a non-conducting state.
