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.
Claims33
A detector, comprising:
- a display;
- a receiver operably configured to sense electromagnetic signals in at least one frequency band characteristic of police traffic surveillance devices;
- a sound pressure transducer configured to sense cockpit sound pressure level in the cockpit of a vehicle within which the detector is located;
- and
- a controller configured to initiate an alert in response to a sensed electromagnetic signal and to initiate depiction by the display of a sensed cockpit sound pressure level.
A method of detecting a police traffic surveillance device with a detector, comprising:
- receiving electromagnetic signals in at least one frequency band characteristic of the police traffic surveillance device;
- sensing a value of a vehicle cockpit sound pressure level;
- generating an alert on the detector in response to detecting a received electromagnetic signal;
- and
- displaying on the detector the sensed value of the cockpit sound pressure level.
An acceleration detector, comprising:
- a display;
- an acceleration sensor configured to sense an acceleration;
- and
- a controller configured to respond to detection of a constant acceleration by said sensor by determining an orientation of said detector.
