  • Publication number: 20170285135
    Abstract: A detector for detecting continuous wave police radar that includes an antenna configured to receive an input signal, a diplexer in communication with the antenna to separate the input signal into a high-band signal and a low-band signal, a local oscillator configured to sweep through a range of frequencies to produce FLO, and a frequency multiplier to generate a first mixing signal that is an integer multiple of FLO. The detector also includes a high-band intermediate-frequency signal and a low-band intermediate-frequency signal with a switch configured to select one of them as an output intermediate-frequency signal. A second-stage mixes the output intermediate-frequency signal with FLO to generate an output signal, and a determination is made whether the input signal includes a police radar signal.

  • Publication number: 20170219687
    Abstract: Detecting continuous wave police radar includes receiving an input signal from a first antenna, the input signal comprising a continuous wave emission within at least one radar band; sweeping a composite local oscillator signal through a range of frequencies from a first frequency to a second frequency in a predetermined time period so that the composite local oscillator signal has a first chirp rate with a first chirp rate magnitude of between 0.15 MHz/?s and 3.5 MHz/?s or even higher; and mixing the input signal from the first antenna with the sweeping composite local oscillator signal to produce an output signal having an intermediate frequency. A next step can include determining that the input signal from the first antenna includes a police radar signal based on the output signal.

  • Publication number: 20170219688
    Abstract: Operating a police radar detector to suppress nuisance radar alerts due to received signals that are not police radar signals includes receiving electromagnetic signals; mixing received electromagnetic signals with a local oscillator signal that is swept at a constant sweep rate; and accumulating a virtual image of the signal environment represented by received electromagnetic signals. Analysis of the virtual image is performed for signals suspected of being nuisance signals that could result in nuisance radar alert so that any nuisance signals within the virtual image can be identified and ignored by the alarm portion of the police radar detector.

  • Publication number: 20120215396
    Abstract: A power supply configured to emulate the functionality of ignition-switched power in a vehicle is configured to plug into an on-board diagnostics port (OBD-II) in the vehicle. The power supply includes a controller that is configured to determine the operating protocol to use and then communicates queries based on the determined protocol to obtain the current values for the engine speed and vehicle speed. The controller compares the current values against predetermined thresholds to determine whether the vehicle operating state is in an ignition-on state. When in the ignition-on state, the controller asserts an enable control signal, which is provided to a switch that responds by switching the un-switched vehicle battery from the OBD-II port to an output interface of the power supply. When the controller determines that the vehicle is no longer in an ignition-on state, the controller de-asserts the enable control signal, thereby removing the power from the output interface.

  • Patent number: 7579976
    Abstract: A radar detector is operated to suppress nuisance radar alerts by identifying a first signal in radar band of interest, e.g., having a frequency that is a harmonic of a first nuisance local oscillator frequency leaked from a nearby radar detector and identifying a second signal having a frequency that is a harmonic of a second nuisance local oscillator frequency leaked from the radar detector where the first and second local oscillators are companion signals. A detector is also provided that suppresses nuisance radar alerts by detecting a first signal in a radar band, providing a first alert designating the detection of the first signal, determining that the first signal is a nuisance signal, providing a second alert designating that the first signal is a false alarm, and turning off the second alert after a predetermined period.

  • Patent number: 5300932
    Abstract: A police radar signal detector detects and monitors radar signals from up to nine (9) radar sources until a detected radar signal has not been redetected for a given number of detector operations, or spectrum sweeps, or until a detected signal has been displaced by a higher priority radar signal. In the police radar signal detector of the present invention, a user of the detector is advised not only of the presence of detected radar signals, the frequency band of detected radar signals and the relative field strength of the signals but also of the number of different radar signal sources which are transmitting signals toward the user's motor vehicle. The information provided to the user for the frequency band of detected radar signals and the relative field strength of the signals is for the highest priority radar signal detected if more than one signal has been detected and is being monitored by the detector of the present invention.

  • Patent number: 5151701
    Abstract: A police radar detector detects both the presence of radar signals incident upon a motor vehicle using the detector and also determines the direction of origin of the source of detected radar signals and alerts the operator of the motor vehicle of the presence and source direction of the radar signals. The radar detector includes at least two antennas and preferably three or more antennas with detector circuitry shared among the antennas in a single detector housing. One of the antennas is directed generally toward the front of the motor vehicle and, for a three antenna embodiment, the second and third antennas are directed at angles of generally 120.degree. to the left and 120.degree. to the right of the front of the vehicle. As the police speed radar frequency bands are scanned or swept, each potential radar signal which is detected is processed to determine the direction of origin of the signals.

  • Patent number: 5116248
    Abstract: A power plug is provided for electrically connecting a receiver of a radar warning detector with an electrical system of a motor vehicle. The power plug comprises a plastic housing having a forward tubular end which is insertable within a lighter socket of the vehicle. Metallic spring arms are mounted within the forward tubular end of the power plug and extend outwardly therefrom to electrically connect the receiver with the vehicle's electrical system. One or more resilient power plug pads are mounted to the forward tubular end of the power plug and serve to frictionally engage the lighter socket to resist movement of the power plug within the socket, thereby ensuring that the power plug remains positioned within the lighter socket even during prolonged periods of operation of the radar warning detector.

  • Patent number: 5083129
    Abstract: A police radar detector detects both the presence of radar signals incident upon a motor vehicle using the detector and also determines the direction of origin of the source of detected radar signals and signals the operator of the motor vehicle of the presence and source direction of the radar signals. Preferably, the radar detector includes two antennas with shared circuitry in a single housing. One of the antennas is directed generally toward the front of the motor vehicle and the other antenna is directed generally to the rear of the motor vehicle. As the police speed radar frequency bands are scanned or swept, each potential radar signal which is detected is processed to determine the direction of origin of the signals. To determine the direction of origin of incident radar signals, the signals are detected in both antennas with the signal strengths in the two antennas being compared to determine the direction of origin of the signals.
