  • Publication number: 20190196019
    Abstract: Method and device for determining a position of a target is disclosed herein. In a described embodiment, the method includes sequentially directing each of a plurality of lighting patterns at the target, each lighting pattern comprising a plurality of illuminations from respective ones of a plurality of emitters, receiving, at a plurality of sensors, reflected illumination of each lighting pattern as reflected from the target; and determining the position of the target using the reflected illuminations of the lighting patterns and a first classifier previously trained to associate the reflected illuminations to a position of the target. In the method, each lighting pattern differs from other lighting patterns by at least an intensity of one of the illuminations; and the intensity of the illumination from at least one emitter is variable between more than two levels. A method of training a classifier for use in the method is also disclosed.

  • Patent number: 8924858
    Abstract: Data transfer system. The system transfers data by touch from a first digital device to a second digital device and includes a first digital device having a touch screen along with a second digital device also having a touch screen. The first and second digital devices are connected to a network including a data storage cloud wherein the first digital device is programmed to copy a touched visual representation of a data item to the data storage cloud and wherein the second digital device is programmed to retrieve the data item from the data storage cloud when a paste-able area in the second digital device is touched. The first and second digital devices may be touch-enabled smart phones, tablet computers or other digital devices.

  • Patent number: 8638966
    Abstract: A sound enhancing system includes a haptic chair formed of a chair and plural speakers mounted to the chair. The speakers receive audio input from a subject audio source and generate corresponding sound vibrations. The chair is configured to deliver the generated sound vibrations to various body parts of a user seated in the chair through the sense of touch and by bone conduction of sound. A visual display viewable by the user corresponds to the generated sound vibrations and is indicative of the corresponding audio input. The sound enhancing system enhances user experience of the audio input by any one or combination of visually, by the sense of touch, and by bone conduction of sound.
