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.
