Abstract: An electronic module for enhancing an operation of a conventional parking meter. The electronic module comprises a shell defining a hollow conformation and being attachable to a conventional parking meter, in substitution to an upper housing portion of that conventional parking meter. The electronic module has a meter condition sensor for detecting from a distant point one of the time expiry indicator and the violative condition indicator of that parking meter, when the indicator is in an indicating mode, and a vehicle sensor affixed to the shell for detecting from a distant point, a parked vehicle. The electronic module further has: an electronic circuitry mounted inside the shell and having a power source for operating the module; means for receiving a first signal from the meter condition sensor and a second signal from the vehicle sensor; means for processing the first and second signals and means for transmitting a coded message to a remote receiver.

Abstract: Circuitry is disclosed that monitors the frequency at which a heater controller applies pulses to a heater to determine if the heater controller is operating properly. If the heater controller fails to generate a pulse in a selected interval, the circuitry generates a signal that activates an alarm and interrupts the operation of a machine that is processing material heated by the heater.
