  • Systems and methods for detecting fake voice commands to smart devices
    Patent number: 11972760
    Abstract: The present disclosure relates to detecting the use of fake voice command to activate microphones of smart devices. In one embodiment, sound characteristics associated with an audio signal from a microphone of smart device may be compared with other microphones of the smart device in order to detect fake voice commands. In another embodiment, sound characteristics associated with the audio signal from the microphone may be compared with a threshold range of stored sound characteristics in order to detect fake voice commands. In some embodiments, a controller may triangulate a position associated with a source of a sound in order to detect a fake voice command. In a further embodiment, a controller may verify that a user or associated electronic device are near a smart device to authorize a voice command.

  • HIGH TEMPERATURE SUPERCONDUCTOR
    Publication number: 20240122080
    Abstract: A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.

  • Secondary back surface touch sensor for handheld devices
    Patent number: 11237603
    Abstract: A second touch area provided on the back side of the mobile phone in a location such that an index finger can be used to provide input when while the mobile phone is being held in that one hand. A second hand is not required for the various types of input that are provided using this second touch area. This allows the mobile phone to be used in single-handed operation in many circumstances.
