  • Publication number: 20220053166
    Abstract: A system controls a teleconferencing device by detecting a current operating state of the teleconferencing device and detecting a contact with a touch-screen device associated with a selection of an audio and a visual input, a selection of an option from a list of options that performs an action in the teleconferencing device, or a transferring of a virtual object between a plurality of devices. The system continuously senses a gesture across the touch-screen device by identifying a first contact with the touch-screen, a distance of a continuous contact with the touch screen, and a last contact with the touch-screen. The process executes a command associated with the selection of an audio and a visual input, the selection of an option from a list of options that performs an action in the teleconferencing device, or the transferring of a virtual object between a plurality of devices.

  • Patent number: 11188145
    Abstract: A computer implemented system controls an electronic device in the absence of a physical contact and/or a radio frequency communication with a user. The system detects the user's presence within a virtual detection range of a camera while the electronic device is in a standby state and transitions the electronic device to an interactive state when the user is detected. The system maintains the interactive state when a detected gesture corresponds to a predefined gesture by processing a comparison of an image of the extended finger against a plurality of images stored in a memory of the electronic device. The system renders a message as a result of the detection of the extended finger and transmits the message as a result of its movement.

  • Publication number: 20210350822
    Abstract: A system automatically controls an electronic device's audio by detecting an active sound source presence within an auditory detection space. The system transitions the electronic device to selectively output a desired sound when the active sound source presence is detected and detects sound in the auditory detection space. The system enhances sound and transforms it into electrical signals. The system converts the electrical signals into a digital signal and identifies active sound segments in the digital signals. The system attenuates noise components in the digital signals and locates the physical location of the active sound source. It adjusts an output automatically by muting a second sound source in a second detection space.

  • Publication number: 20210297467
    Abstract: A system controls an electronic device in a teleconferencing system through remote screen-receiving devices that access software applications on a screen-sending device. Access is provided through a point-to-point private wireless network. The software applications are replicated on the remote screen-receiving devices. The software allows users of the remote screen-receiving device to simultaneously manipulate or use one or more common software applications. The concurrent manipulation or use occurs without the screen-sending device applying a software application locking.

  • Publication number: 20210294424
    Abstract: A system automatically frames locations by detecting a user's presence within a virtual detection space. The system detects sound in the detection space and converts the sound into electrical signals. The electrical signals are converted into a digital signals at common or periodic sampling rates. The system identifies speech segments in the digital signals and attenuates noise like components within or adjacent to them. The system identifies the physical locations of a speech source generating the speech segments and automatically adjusts a camera framing based on the estimated location of the active speech source generating the speech segments.

  • Patent number: 10875161
    Abstract: A lockable torque wrench with adjustment indication includes a rod body, a handle, a plurality of rollers having a rolling pillar, a rotation ring, and a pressing member. The rod body is combined into the handle and rotatable to protrude or retract against the handle for adjusting the torque. The rotation ring is disposed on an extension tube of the handle and mounted around the rollers. The rotation ring is switched between a locked and a relax positions. The pressing member has combination portions at two sides of the extension tube, and permanently engages the rolling pillar. In an ascend position, the rolling pillar is pressed toward the rod body by the prestress force supporting the pressing member. When meeting a position limiting groove, the rolling pillar is pressed to lower in the position limiting groove, providing a switch sensation formed for the user.
