Abstract
A police activity transponder utilizes data available through a vehicle on-board diagnostic system or a intelligent vehicle data bus to adjust the sensitivity of the police activity transponder to law enforcement signals based on speed data. A police activity transponder is configured to read speed data available through an on-board diagnostic system or an intelligent vehicle data bus and using an internal clock, calculate a 0 to 60 mile per hour or a quarter mile time for display and function as a speedometer. A police activity transponder is configured to read engine revolutions per minute (rpm) data and function as a tachometer. A police activity transponder is configured to allow a user to input shift points, read engine rpm data, and provide a user indication.
