Abstract: Described are devices for automatically adapting electrical polarity from a power source to a specified output polarity for use by an electrical load. In one implementation, power adaptation circuitry comprising one or more bridge circuits accept electrical power of unspecified polarity and output specified polarity. The bridge circuit may comprise a plurality of field-effect transistors (FETs) configured such that a particular subset of the FETs are energized to conduct electric current to the outputs when a particular polarity is applied at inputs.

Abstract: An architecture is provided to generate an augmented reality environment and visualize or otherwise output information about changes to a physical object within the environment. The changes may include location, quantity, condition of the physical object, and so forth. Users may also use a rendering of a physical object to plan layout of the physical object in the environment. Prompts may be provided to guide placement of the physical object.

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.
