Problems solved by technology

Optionally, the user may employ one or more monitoring devices to reduce the subjectivity of the analysis, however, even with such tools, the user is still required to interpret the results from each monitoring device for position adjustment or zoom balance

Embodiment Construction

[0012] For ease of presentation and understanding, the invention is represented here using the example of an audio system having distributed speakers for radiating sounds and microphones for detecting these sounds. It will be apparent to one of ordinary skill in the art, following this description, that the invention can be applied to other systems having distribution equipment, and is independent of the particular transmission and reception techniques used.

[0013] figure 1 An example system 100 is shown having multiple devices 110a-e distributed in an environment. Taking the audio system as an example, devices 110a, 110b and 110c correspond to left, center and right front speakers, respectively, while devices 110d and 110e correspond to left and right rear speakers, respectively. A system controller 120 controls the signals provided to each device 110a-e. For ease of reference, the identifier 110 is used below to refer to any or all of the devices 110a-e when the context ...

Abstract

Detection devices are provided within the system and utilized to determine the location of the radiation device. The detection device and the radiating devices are co-located, thereby allowing the relative position of each radiating device to every other radiating device to be determined without obtaining the absolute position of each radiating device. Given the location of each device, one or more aspects of the system are adjusted to improve system performance. In an audio system, the configuration and placement of speakers can be adjusted to provide the correct sound balance. In wireless systems, the configuration and placement of base stations can be adjusted to prevent gaps in coverage. The relative location of the target radiation can also be determined and adjustments made to the system to optimize system performance relative to the location of the target radiation.

Description

technical field [0001] The present invention relates to the field of electronic systems, and in particular to systems in which the position of a device within the system affects the performance of the system. Background technique [0002] Various systems are based on physically or geographically dispersed devices. For example, advanced sound systems often require four or five speakers distributed in a room to produce a true reproduction of a recorded performance. Wireless networks require base stations to be distributed throughout a building or other geographic coverage area. Other examples of distributed systems whose performance depends on the distribution of components within the system or decentralized distribution systems are known to those skilled in the art. [0003] In general, the location of each component in the distribution system is assumed to be known, or assumed to be specified. For example, in a cellular telephone system, the location of each base station / ...
