A system includes a controller including a housing and a mechanism for generating RF output signals. The output signal generating mechanism includes controls mated to the housing. A mechanism is included for uniquely coding the output signals so that each output signal is detected by only a corresponding object. A mechanism is included for displaying a date and time. A radio mechanism is included for tuning into a radio station and playing an audible signal. A base station is mated with a power supply source and includes a transformer and an electrical contact coupled thereto. The controller is engageable with the electrical contact for being recharged. The base station includes a bottom layer formed from rubber material for maintaining same stable during recharging conditions. The system includes objects including transceivers housed therein and a mechanism for decoding the output signals such that the objects can generate and transmit response signals.
