  • Patent number: 9979953
    Abstract: The depth of one or more objects within a scene may be determined utilizing system that includes a single light source, a reflector (e.g., an ellipsoidal reflector), a shutter mechanism associated with the light source, and a camera. More particularly, the light source may output light that is directed towards the scene (a first set of light beams) and towards the reflector (a second set of light beams) utilizing the shutter mechanism. The reflector may reflect the second set of light beams towards the scene. The camera may then capture a first image that corresponds to the first set of light beams and a second image that corresponds to the second set of light beams. The depth of a particular one of the objects within the scene may be determined based at least in part on the first image and the second image.

  • Patent number: 9541125
    Abstract: Projection and camera systems may employ a joint locking mechanism that may enable a user to reposition or move structures (arms, lenses, etc.) that are otherwise locked in position. The joint locking mechanism may include a touch-activated presence detector to sense a presence of an extremity of a user. In response to the presence detector sensing the presence, an actuator may unlock a joint or structure to enable movement of the joint or structure while the presence detector continues to sense the presence. In response to a detection of an absence of the extremity, the actuator may return to a locked state to prevent further movement of the joint or structure.

  • Patent number: 9472005
    Abstract: A device includes a projection and camera system to create an augmented reality environment in which images are projected onto a scene and user movement within the scene is captured. The projection and camera system have a camera to image scattered IR light from the scene and compute time of flight values used in depth mapping of objects in the room. The system also has a projector to project the images onto the scene. The projected images and scattered IR light use a common optical path through the same lens. Additionally, an illumination system used to illuminate the scene with the IR light may also use the common optical path through the same lens. In one implementation, the projection and camera system are mounted in a movable head of a table lamp.

  • Patent number: 9461570
    Abstract: A stepper motor may be controlled by a controller to provide extended revolution of a motor shaft while operating in a first mode and to allow a user to manually intervene with an intended position or rotation of the motor shaft while operating in a second mode. In some embodiments, the controller may adjust a torque applied to the stepper mode during operation of the stepper motor. The controller may reduce a torque applied by the stepper motor to a lower torque while the user intervenes with the intended position or rotation of the motor and increase the torque to a holding torque after the user intervention has ended. Thus, the controller may dynamically adjust a torque of the stepper motor in response to detection of the user intervention.

  • Patent number: 9281727
    Abstract: A user device may include one or more features on a surface of the user device, where a user may interact with the one or more features. In response to a user action with respect to one of the features, a particular sound, frequency, or change in frequency may be output. An augmented reality functional node (ARFN) may detect the sound or frequency and identify a particular operation that corresponds to the sound or frequency. The ARFN may then cause that operation to be performed within an environment.

  • Patent number: 9261759
    Abstract: Techniques are described for compensating for distortion effects caused by projecting images to a surface that is non-perpendicular to a raster-scanning laser projector. Pixel size is modulated such that smaller pixels are projected to farther portions of the surface, and larger pixels are projected to nearer portions. Pixels within a raster scan line may have their lengths modulated through variation of a frequency of light source that generates the pixels, or through adjustment of a scan speed along the line. Pixel heights may be adjusted by modulating the distance between scan lines. Scan speed and distance between scan lines may be modified by controlling micromirrors incorporated into the laser projector for directing the light projection.

  • Patent number: 9262983
    Abstract: Described herein are systems and techniques for projecting content, periodically or continuously, onto a rear surface of a display medium from behind. The rear projected image is presented on an opposing or front surface of the display medium to a human audience for viewing. Additionally, non-visible light (e.g., IR light) is passed through the display medium to an area in front of the medium. The non-visible light is used to detect human gestures. In this manner, the rear projection arrangement avoids viewer obstruction during projection, yet detects and recognizes gestures made by the viewer in front of the display medium.

  • Patent number: 9127942
    Abstract: In some embodiments, a distance between the at least one light sensor and the surface may be calculated using a ratio representative of the phase difference using time-of-flight of light. The distance may be within a distance range defined by a distance of light travel during a modulation period of the predetermined frequency. The distance may be based on the ratio defined by an amount of energy stored from captured light during a first time interval and a second time interval, and a comparison of an amount of light stored from captured light during at least a third time interval. The first, second, and third time intervals are different, but may overlap in some instances. In some embodiments, the amount of ambient light may be identified and subtracted from the inputs of the ratio. A switch may be used to prevent oversaturation of a storage element storing the stored energy.

  • Patent number: 9069065
    Abstract: Techniques are described for determining locations of audio sources. Audio signals are captured from multiple locations. Pairs of the audio signals are analyzed to create correlograms, indicating correlation scores corresponding to different time offsets between the signals. Based on the correlograms, various locations are analyzed to determine probabilities of audio originating from those locations. The highest probabilities are found, indicating locations containing audio sources. In some situations, the audio sources may be reflective sources, and the locations of the reflective sources may be used to determine locations of objects or surfaces.
