Abstract
A police radar and/or laser detector senses radiant electromagnetic signals (e.g. radar, laser) characteristic of a police traffic surveillance device and responds thereto with a displayed and/or audible alert. During periods when no alert is necessary, the detector senses and displays, in numeric or bar graph form, vehicle parameters, such as sound pressure level and acceleration. In addition, calculations based on acceleration provide 0-60 m.p.h. time and quarter mile time. Thereby, the detector enhances information available to the driver without the inconvenience, expense, and clutter of multiple displays.
