Abstract: Printed circuit boards (PCBs) are configured with an athermalized mounting suitable for securing and positioning and the PCBs within an inertial measurement unit (IMU). The PCBs include integrated circuit (IC) components, such as accelerometers and/or gyroscopes, which require relative positional stability within the IMU environment in order to provide accurate results. The athermalized mounting configuration of the PCB enables the PCBs to experience thermal expansion within the IMU without causing significant displacement of the IC relative to the IMU environment.

Abstract: An environment detection node supports dynamic audio optimization by receiving data from sensors and analyzing the received data to detect objects such as furniture and/or humans within an environment. Based on locations within the environment of the detected objects, the environment detection node determines an optimized target location and adjusts audio output to be optimized when heard at the target location.

Abstract: A self-calibrating display system includes a stereoscopic, near-eye display device, a docking unit, and one or more cameras. The display device includes one or more coupling structures, in addition to one or more microprojectors configured to project a right calibration image and a left calibration image. The docking unit includes one or more complementary coupling structures, each being releasably lockable to a coupling structure of the display device, to prevent movement of the display device relative to the docking unit. The one or more cameras are configured to acquire a secondary image of the right calibration image and a secondary image of the left calibration image.

Abstract: Display media configured to receive projected content are described herein. In some instances, a display medium may be a non-powered object that a user may hold and move in different ways through a room or other environment. The display medium may be formed to fit into the user's hand and include elements that provide information to accurately project an image onto the display medium or to perform other actions.

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.

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.

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 system controls the camera and projector mounted in a moveable head of a lamp with a motor mounted elsewhere in the lamp. In one implementation, the motor is mounted in the base of a table lamp.

In one implementation, the projection and camera system are mounted in a movable housing or head that is supported by a repositionable support structure. The housing can be moved to a desired position and then locked into a stationary and stable position for creation of the augmented realty environment.

Abstract: A video conferencing device has a projector that can be controlled to project far-end video onto different available display surfaces. A panoramic camera is mounted so that it captures a horizontal panorama that includes near-end users. When projecting far-end video, a display surface is selected based on the position of the users. Specifically, a display surface is selected such that when gazing at the far-end video the faces of the user are visible from the panoramic camera.
