Patent ID: 8866599

Claim:
A signaling system to generate a plurality of signals indicating specified events relating to a plurality of defined areas and to connect different ones of the signals to different ones of the defined areas, the signaling system comprising: a plurality of first mobile signal devices for generating first signals, the plurality of the first mobile signal devices including a plurality of sets of the first mobile signal devices, each of the sets of the first mobile signal devices being associated with a respective one of the plurality of defined areas, user to generate the first signals to indicate specified events relating to said respective one of the plurality of defined areas; a plurality of second signal devices for generating second signals, the plurality of second signal devices including a plurality of sets of the second signal devices, each of said sets of the second signal devices being associated with a respective one of the defined areas, wherein each of the defined areas is associated with one of the sets of the first mobile signal devices and with one of the sets of the second signal devices; a control subsystem for selectively connecting different ones of the sets of the first mobile signal devices with different ones of the sets of the second signal devices, the control subsystem including one or more transceivers for receiving event signals from the first mobile signal devices, and for generating activation signals and for transmitting the activation signals to the second signal devices to activate the second signal devices to generate the second signals the one or more transceivers having a plurality of different operating frequencies; and a control to set the operating frequencies of the one or more transceivers to use said operating frequencies of the one or more transceivers to connect each of the sets of the first mobile signal devices with the one of the sets of the second signal devices associated with a same one of the defined areas as said each set of the first mobile signal device is associated with; and wherein when each of the first mobile signal devices of each of the sets of the first mobile signal devices generates one of the first signals to indicate one of the specified events relating to the defined area associated with said each set of the first mobile signal device, said each first mobile device sends an event signal to one of the operating frequencies of the one or more transceivers, in response, said one or more the transceivers sends an activation signal to the one of the sets of the second signal devices associated with the same one of the defined areas as said each set of the first mobile signal devices, and each of the one set of the second signal devices generates one of the second signal to confirm that said each of the first signal devices has generated one of the first signals to indicate one of the specified events related to said same one of the defined areas.
