Electronic Meter Seal Arrangement Tamper Detection

The patent replaces mechanical switch mechanisms with an electronic sealing system that uses a seal bit in electronic memory to record tamper events. The system employs a processing circuit that monitors physical conditions (such as cover removal) and updates the seal bit state electronically, eliminating reliance on mechanical switches that can be bypassed with mechanical skills.

The patent creates an electronic copy or representation of the tamper detection state through the seal bit in electronic memory. Instead of relying on physical mechanical switches, the system uses digital bits to represent the sealed/unsealed state, which can be read and verified without physical manipulation of the meter components.

The patent implements preliminary action by requiring specific conditions to be met before the seal bit can be reset. The system pre-establishes rules that the seal bit may only be cleared when certain criteria are satisfied (such as proper authentication, specific operational states, or verified integrity conditions), preventing arbitrary or unauthorized resets after tamper events.

The patent changes the parameters or conditions under which the seal bit can be modified. Instead of allowing free reset, the system implements conditional logic that changes the state requirements for clearing the seal bit, making it dependent on specific system states, authentication credentials, or operational parameters that prevent unauthorized manipulation.
