Signalling is the subclass of Guiding processes in which an agent, animate or inanimate, sends a signal to another Object. In many cases, this signal will be an electrical or electronic one. Some signals may directly control the behavior of the object signalled, while others may merely cause information to be presented. Instances of electrical Signalling are typically more complex than simply than operation of a DeviceSwitch, though in some cases, Signalling involves remote activation of such a switch by another device.
