摘要： A usage specification device is used to limit the use of information signals (audio, image, data) and to limit the output of disturbing signals (speaker, flash, light, RF transmission) in several devices in a large restricted area. For example, the usage specification device may transmit a certain type of control signal to disable image capture by camera-equipped portable/mobile devices, or it may transmit other types of control signals to disable audio capture or data capture by such devices. Similarly, the specification device may transmit a certain type of control signal to reduce the speaker volume on portable/mobile devices, or it may transmit other types of control signals to disable the flash, or minimize the intensity of light emitted by the display or restrict the transmission of RF signals from such devices. Due to such features, only undesirable features of portable/mobile devices may be prevented in restricted areas, while permitting other uses. According to another aspect, the device can be scanned by an external scanner for a built-in code, with the code indicating the specific type of capabilities the device has and the specific type of usage controls supported by the device. Accordingly, the owner of a premises may first scan a device to determine the specific capabilities and control features supported before permitting the device to be carried into the premises.
