Abstract: A method includes: obtaining a reference stereo image from a stereo camera assembly of a mobile computing device; detecting a reference surface from the reference stereo image; determining an inclination angle of the reference surface relative to an output vector of an auxiliary sensor of the mobile computing device; obtaining a first dimensioning stereo image from the stereo camera assembly; detecting the reference surface in the first dimensioning stereo image based on the inclination angle; detecting a first object surface in the first dimensioning stereo image; and generating dimensions of the object based on the first object surface and the reference surface.

Abstract: A mobile device accessory for measuring a dimension is described. The accessory includes a housing having a mating feature that is adapted to mate with a corresponding mating feature of a mobile device. A measuring tape includes a detectable pattern thereon. The detectable pattern is related to the dimension. The accessory also includes a detector that generates a signal in response to detecting the pattern. A processor generates dimension data in response to receiving the signal. An interface transmits the dimension data to the mobile device.

Abstract: Described are a method, a communication device, and a system for enabling a toy mode on a telephone. The method includes operating a device in a first operating mode, the first operating mode being a full functional mode, receiving a selection for a second operating mode while the device is operating in the first operating mode, the second operating mode being a reduced function mode, and configuring the device to operate in the second operating mode, wherein the configuration includes altering an operation of a communication interface of the device.
