Embodiment Construction

[0021] 1 is a partial block diagram of a wireless communication device 10 including one or more processing circuits 12 and a rangefinder 14 , which may include sensor circuitry 16 and a distance sensor 18 . Distance sensor 18 may comprise an infrared or laser based emitter / sensor pair, or an ultrasonic transducer, or other type of distance measuring sensor, and sensor circuitry 16 may be configured to provide suitable control and bias signals as desired.

[0022] Irrespective of its implementation details, the rangefinder 14 is configured to generate a distance measurement signal by emitting a distance measurement signal and detecting a corresponding reflected signal back from a nearby (local) object 20 . To complement this arrangement, the aforementioned one or more processor circuits 12 are configured for processing distance measurement signals and outputting corresponding distance measurement information via the wireless communication device 10 .

Abstract

A wireless communication device includes a range finder, and is configured to obtain distance measurements via the range finder for processing by the device. Such processing may comprise, by way of example, storing distance measurement information, outputting distance measurement information on a display screen of the wireless communication device, transmitting distance information to a wireless communication network, or outputting tones, pulses, or vibrations as a function of the distance measurement information. The wireless communication device may include a camera, and the range finder may be aligned with the camera, such that related distance information may be obtained for objects imaged by the camera.

Description

technical field [0001] The present invention relates generally to wireless communication devices, such as cellular radiotelephones, and, more particularly, to incorporating ranging functionality in such devices. Background technique [0002] Historically wireless communication devices provided only basic communication functions. Even at times, the basic functionality is rather limited. Limited battery performance and a lack of inexpensive user interface elements (graphical displays, decent audio components, etc.) are some of the reasons for the lack of extra features found in earlier wireless communication devices. Furthermore, adding more than a baseline set of communication features to an already larger than desired size device was simply not practical prior to modern advances in device miniaturization. [0003] Network capabilities are also considered in the features. In addition to providing traditional circuit-switched voice and fax services, early wireless communica...
