  • Detecting item scans with audio signal processing
    Patent number: 10055628
    Abstract: Disclosed are various embodiments for detecting item scans with audio signal processing. A first machine-readable identifier may be rendered in a display device associated with at least one computing device, where the first machine-readable identifier is associated with a first item in a list of items. An audio signal may be captured using a microphone and analyzed to identify a predetermined tone in the audio signal indicative of a scan being performed on a register device. In response to the predetermined tone in the audio signal being identified, the first machine-readable identifier may be replaced with a second machine-readable identifier in the display device, where the second machine-readable identifier is associated with a second item in the list of items.
    Type: Grant

  • MOBILE DEVICE BATTERY WARNING FOR DATA DOWNLOADS
    Publication number: 20060264197
    Abstract: A method of determining the power required by a mobile device to download a desired file from a remote source. The method estimates the power needed to download the desired file from the remote source. The method then estimates the remaining power currently available to the mobile device. The two estimates are then compared. The mobile device will display a warning when the estimated power required to download a desired file from the remote source is within a predetermined value to the estimated remaining power currently available to the mobile device.
