`RADAR DETECTOR ARRANGEMENT
`
`FIELD OF THE INVENTION
`
`The present invention relates generally to radar detectors,
`and in particular, to radar detectors useful in motor vehicles
`in which false alarms are reduced or eliminated.
`
`<
`
`BACKGROUND OF THE INVENTION
`
`In many current radar detectors, false alarms, i.e., the
`occurrence of an alarm as a result of radar signals emanating
`from fixed objects (such as burglar alarms) rather than from
`a radar speed detection device operated by law enforcement
`personnel, have become a problem. Generally, false alarms
`are avoided by including a manually operated switch that
`can reduce sensitivity of the detector in geographic areas,
`such as areas in which there are many businesses that have
`alarm systems that transmit energy in bands monitored by
`the radar detector. This is problematic, however, if a speed
`tracking radar system is operating in the same geographic
`area, since the real system either will not be detected (due to
`the decrease in sensitivity) or will be detected only when the
`radar detector is very close to the tracking system, which
`may be too late.
`SUMMARY OF THE INVENTION
`
`In accordance with the present invention, a radar detector
`is equipped with a positional tracking system, such as a
`global positioning satellite (GPS) system which can track
`the location of the vehicle in which the detector is located,
`and a processor enabling the detector to “learn" about the
`location of sources of false alarms, and optionally, other
`information about the characteristics of the false alarms. The
`learned information is stored in a “false alarm” database. In
`this way, when an alarm is detected at
`a
`later time,
`a
`comparison in made between the information relating to the
`alarm and the stored information, for example by comparing
`the present location of the vehicle in which the radar detector
`is located and stored information indicative of known loca-
`tions at which false alarms have previously occurred. If the
`comparison is positive, the alarm is disabled, or the user is
`otherwise alerted to the fact that the alarm is likely to be
`false.
`
`The present invention can be enhanced by storing addi-
`tional
`information about false alarms, such as a signal
`strength profile,
`time of day infonnation, or information
`identifying the frequency band of the signals which caused
`the alarm, during a learning mode, and using that informa-
`tion for comparison purposes during an operating mode. A
`further enhancement may use other information such as the
`direction of the moving vehicle to more accurately deter-
`mine the veracity of the alarm.

`
`DETAILED DESCRIPTION
`
`Referring first to FIG. 1, there is shown a block diagram
`of a radar detector arranged to avoid or reduce false alarms
`in accordance with the present
`invention. The detector
`includes a conventional radar detector portion 100, and an
`“add-on” portion 150 that provides the false alarm reduction
`functionality of the present invention.
`The conventional radar detector portion 100 includes the
`components of a commercially available radar detector, such
`as the Escort model available from Cincinnati Microwave.
`Specifically, portion 100 includes a radar energy detector
`101 that is arranged to sense the presence, in the present
`geographic location of the radar detector, of electromagnetic
`energy in one or more frequency bands associated with the
`use of speed detection radar as might be employed by police
`personnel. The output of detector 101 is applied to a
`processor 103, which compares the detected energy with a
`thre ‘hold, aid issues a control signal to alarm generator 195
`if the energy in one or more frequency bands exceeds a
`threshold. Many radar detectors include a sensitivity control
`107 coupled to processor 193, that may function to selec-
`tively increase the threshold, or to change the frequency
`bands being monitored,
`in order to avoid false alarms.
`Ilowever,
`the sensitivity control
`is normally operated
`manually, such as when the motor vehicle in which the radar
`detector is located is passing through an area where there are
`many sources of energy in the same or similar bands as that
`detected by detector 101. These areas might be near shop-
`ping oenters or other commercial areas where there are
`burglar alarms or door openers that use “radar” types sys-
`tems to sense the presence of movement. When the threshold
`is exceeded, alarm generator 105 may issue an audible,
`visual or other type of alert to the user of the detector.
`In accordance with the present invention, an “add-on”
`portion 150 of the radar detector, which may generally be
`incorporated in the same housing as the conventional radar
`detector portion 100, includes a positional tracking system,
`such as a global positioning satellite (GPS) module 151 that
`is arranged to provide an output to a processor 153 indicative
`of the current location of the object (in this case, the motor
`vehicle containing the radar detector) in which the module
`is located, Various GPS systems are currently commercially
`available, such as the Garmin GPS 38 described on the
`Internet at http:/./wwwflexicomm.com/views/features/'
`mar97/spccshtml. These systems are small, can be battery
`operated and are easily integrated into other devices, such as
`is contemplated herein.
`Processor 153, which may be a separate processor or use
`some or all of the processing functionality of processor 103,
`is arranged to perform the processes described below in
`connection with FIGS. 2 and/or 4, under the control of
`program instructions which may be stored in a database 155
`or in a short term memory 159 which may be a random
`access memory (RAM) chip. Database 155 (or other suitable
`memory), in addition to storing instructions, is also arranged
`to store location information generated by GPS module 151,
`and to enable retrieval of stored information, such that the
`stored information can be compared to the current informa-
`tion. For example, the current location of the object in which
`the GPS module is located can be compared to previously
`stored location information,
`to determine if the current

`location is at or near a location previously visited.
`Alternatively, or in addition, the time of day or frequency
`band that cause the alarm can be compared with the time of
`day or frequency band that previously caused a false alarm.
`A mode switch 157 can be used by the user of the radar
`detector to indicate if the device is in the learn mode, in
`which the location of false alarm sites is stored in database-
`155, or in the operate mode, in which the occurrence of false
`alarms is reduced or eliminated when the radar detector is in
`actual use.
`
`Referring now to FIG. 2, a flow chart indicating the
`process followed by the radar detector of FIG. 1 during
`“learn” and “operate” modes. The process begins in step
`201, when the radar detector is turned on, and proceeds to
`step 203, in which the output of detector 101 is compared to
`the then current
`threshold T to determine if an alarm
`indication should be generated. If a NO result occurs in step
`203, the process continues by repeating step 203, thereby
`constantly monitoring for the occurrence of an alarm con-
`dition.
`
`When sufficient energy is detected such that the output of
`detector 101 exceeds the threshold T, a positive result occurs
`in step 203 and the process proceeds to step 205, in which
`the current location of the radar detector is determined using
`the output from GPS module 151. Next,
`in step 207, a
`determination is made as to whether mode switch 157 is in
`the learn or operate mode.
`If the device is in the learn mode, the process proceeds to
`step 209, in which the current location or other information
`about the alarm, such as the time that it occurred or the
`frequency band of the signal causing the alann, is stored in
`database 155. The process then returns to monitoring for an
`alarm, by repeating step 203.
`If the device is in the operate mode, the process proceeds
`from step 207 to step 211 in which the current information,
`such as the location of the motor vehicle, is compared with
`locations already stored in database 155. If a match exists,
`meaning that the radar detector is near or at the location
`where a previous false alarm occurred, a positive result
`occurs in step 213, and the process proceeds to step 209, in
`which additional information stored in database 209 can be
`processed. As indicated above, this additional information
`can, for example, indicate the number of times that a false
`alarm has been detected at the present location, the time of
`day that the alarm occurred, the frequency band that caused
`the alarm, and so on. Using frequency band as an example,
`the software operating the processor of the present invention
`is advantageously arranged so that a false alarm would not
`occur even if the present alarm occurred at a location that
`was at or near the site of a previous false alarm, unless the
`frequency band that caused the false alarm was the same as
`the frequency band presently being detected. Alternatively,
`the process can proceed directly from a positive result in step
`213 back to step 203. In either event, note that an alarm
`activation does not occur, because the signal
`that was
`detected was a false alarm.
`On the other hand, if no match exists when the current
`location is compared t.o stored locations in database 155, (or
`even if there is a match, but the other compared information,
`such as frequency band is different) a NO result occurs in
`step 213, and the process proceeds to step 215, wherein
`alarm generator 105 is activated.
`It is also within the scope of the present invention to store
`in database 155 an indication of signal strength of the false
`alarms, so that, when a subsequent alarm in the same
`geographic location occurs, a comparison can be made to
`determine that there is approximately the same amount of
`energy (indicating a false alarm) as opposed to an additional
`amount of energy (indicating the presence of a radar speed
`tracking device).

`Referring now to FIG. 3, there is shown a diagram which
`illustrates an embodiment of the invention in which the
`alarm information that is stored is both position and direc-
`tion sensitive. A road 350 running East to West is located in
`proximity to a building complex 340. The building complex
`340 generates a false alarm zone 300 at certain times of the
`day, such that a vehicle traveling on road 350 from West to
`East enters zone 300 at point A and leaves zone 300 at point
`B. At other times of the day, the electrical equipment at
`building complex 340 that is the root cause of the false
`alarms may be turned off,
`thereby deactivating the false
`alarm zone 300.
`In accordance with the present invention, a radar detector
`is arranged to store information indicative of the geographic
`locations of points A and B,
`time of day information
`indicative of when false alarms occur, and of the fact that the
`false alarm zone extends between these two points when the
`vehicle is traveling from West to East. Thus, if radar trap
`equipment 330 is operating in the vicinity of road 350 such
`that a detection zone 360 is established, when vehicle 320
`enters that zone at point C, while traveling from West to
`East, the presence of radar energy generated by equipment
`330 will be detected. A determination of whether this alarm
`is “false” or “genuine” can be made to depend upon several
`factors, each of which involves the information stored
`previously in the radar detector during the learn mode.
`First, the stored time of day information for false alarms
`can be compared to the current time of day, to rule out a false
`alarm (i.e., to indicate that an alarm is genuine) if the times
`are different. Second, the detector can determine that the
`location of vehicle 320 at detection point C is well within the
`segment of read 350 between points A and B where false
`alarms are normally encountered. In view of this possible
`overlap of false alarm and genuine alarm zones, signal
`strength readings may be compared,
`to determine if the
`amount of energy detected by the detector is above that
`normally measured due to building complex 340. If so, the
`alarm is determined to be genuine, and the user is alerted.
`This allows the present invention to operate satisfactorily
`even when the radar trap equipment 330 is located at a
`location within the area normally causing false alarms.
`Referring now to FIG. 4, there is shown a flow chart
`depicting an alternative process used by a radar detector
`arranged in accordance with the present invention to selec-
`tively operate in a learn mode,
`in order to reduce the
`occurrence of false alarms.
`In this embodiment,
`it
`is
`assumed that the radar detector of FIG. 1 includes both a
`database (155 in FIG. 1) arranged for long term storage of
`alarm information as well as a short term memory (159 in
`FIG. 1)
`in which such information may be stored.
`Furthermore, in this embodiment, the mode switch (157 in
`FIG. 1) operates as a “momentary contact” switch, which
`can be depressed by a user to effect transfer of the contents
`of the short term memory to the database for longer term
`storage.
`The process of FIG. 4 begins in step 400, in which the
`radar detector is in a ready state, monitoring for the presence
`of energy in the bands normally transmitted by speed
`detection radar equipment. When such energy is detected,
`information regarding the alarm (e.g., location of alarm,
`time of alarm, direction of travel, band identification, signal
`strength, etc.) is collected in step 410 and stored in short
`term memory in step 420. Next, in step 840, a determination
`is made as to whether the alarm is false or genuine. As
`indicated above, this involves comparing information about
`the present alarm with information about characteristics of
`previous alarms that were known to be false.
`If the alann is determined to be false, a YES result occurs
`in step 440, an alarm signal is not generated, and the process
`proceeds to step 445 in which the short term memory is
`
`K40 Exhibit 1015, pg. 8

`

`cleared. The detector then returns to the ready state and
`repeats step 800. On the other hand, if the alarm is not
`known to be false (e.g., information relating to that location,
`time, frequency band, etc. is not stored in the database), a
`N0 result occurs in step 440, and the process proceeds to
`step 450,
`in which an audible beep (or other similar
`notification) is provided to the user. At this point, the user
`can choose to activate the momentary contact switch to
`thereby activate the “learn function” of the detector. lf this
`is done, a YES result occurs in step 460, after which the
`information contained in the short term memory is trans-
`ferred to the database in step 470.
`If the learn mode is not activated by a user, a NO result
`occurs in step 460 and the process proceeds to step 475, in
`which a determination is made as to whether the detector is
`receiving additional alarm information. If not, a NO result
`causes the process to proceed to step 485, in which the short
`term memory is cleared. The process then returns to step
`800. On the other hand, if a YES result occurs in step 475,
`the process repeats step 450 by informing the user again with
`a beep or other alerting indication.
`After step 470 is performed, the process proceeds to step
`480, in which a determination is made as to whether the
`detector is receiving additional alarm information. If YES,
`the information is stored in the long term database in step
`490; if NO, the learn mode is deactivated in step 482, the
`short term memory is cleared in step 485 and the process
`returns to step 400.
`Various modifications and enhancements to the present
`invention may be made by persons skilled in the art. For
`example,
`the time of day, mentioned previously, can be
`obtained by providing a clock chip Within “add-on” portion
`150. If each location stored within database 155 is tagged
`with the time that the false alarm occurred, then a further
`comparison of the current time to the false alarm time can be
`used as an indicator to determine if an alarm is more likely
`to be real or false.
`
`In addition, while the process of FIG. 2 contemplates that
`a YES result in step 213 prevents alarm activation, it may be
`desirable to instead increase the threshold for an alarm in the
`event that the location at which an alarm occurs matches the
`location of a previous false alarm. In this way, it
`is still
`possible for the radar detector to detect the presence of an
`additional source of radar frequency energy located at or
`near the same location as the source of the false alarm. As
`a further alternative, an alarm signal may be generated in
`such a way as to indicate to the user that the alarm is likely
`to be false.
`What is claimed is:
`1. A radar detector including
`means for detecting the presence of energy in at least one
`specific frequency band associated with speed detec-
`tion radar,
`means responsive to the detecting means for selectively
`generating a discernable alarm,
`a positional tracking system arranged to generate infor-
`mation indicativc of the location of the vehicle in which
`the detector is located,
`means for storing said information upon the occurrence of
`a false alarm, and
`a processor for disabling said alarm generating means in
`the event that the alarm occurs when said vehicle is in
`a location substantially the same as a location previ-
`ously stored in said storing me ans.
`2. A radar detector including
`a positional
`tracking system for providing location
`information,
`.
`
`a database for storing said location information,
`means for entering information from said positional track-
`ing system in said database upon the occurrence of a
`false alarm, and
`means for comparing location information indicative of
`the present location of said radar detector Willi infor-
`mation in said database before alerting a user of said
`detector to an alarm condition.
`
`3. A radar detector having a learn mode and an operate
`mode, said radar detector comprising
`a database for storing information generated when said
`detector is in said learn mode, indicative of conditions
`associated with false alarms detected by said detector,
`and output means for alerting a user to the occurrence
`of an alarm detected by said detector, and
`a processor for comparing information generated when
`said detector is in said operate mode with said stored
`information prior to activating said output means.
`4. The invention defined in claim 3 wherein said radar
`detector includes a positional locating system and wherein
`said information includes the location of said radar detector
`obtained during said learn and said operate modes.
`5. The invention defined in claim 4 wherein said posi-
`tional locating system is a GPS system.
`6. The invention defined in claim 5 wherein said infor-
`mation includes the frequency band of the radar energy
`received by said detector during said learn and said operate
`modes.
`7. A radar detector including
`means for storing information indicative of the location of
`said detector during the occurrence of a false alarm,
`means for comparing said stored information with infor-
`mation indicative of the location of said detector during
`the occurrence of a subsequent alarm, and
`means for alerting the user of said radar detector only if
`said subsequent alarm occurs at a location substantially
`different from the location indicated by said stored
`information.
`8. Portable apparatus arranged to be carried in a motor
`vehicle for detecting the presence of energy in one or more
`frequency bands emitted by speed detection radar, said
`apparatus including
`means operative in a learning mode and responsive to the
`detection of the presence of energy in one or more
`frequency bands emitted by speed detection radar that
`exceeds a
`threshold value for storing information
`indicative thereof;
`means operative in an operating mode and responsive to
`the detection’ of the presence of energy in one or more
`frequency bands emitted by speed detection radar that
`exceeds a threshold value for comparing information
`indicative thereof with said stored information, and
`means for generating an alarm perceptible to a user only
`if said comparison indicates that said stored informa-
`tion is substantially different from said compared infor-
`mation.
`9. The invention defined in claim 8 wherein said infor-
`mation is indicative of the geographic location of said
`portable apparatus.
`10. The invention defined in claim 9 wherein said in for-
`mation is further indicative of the frequency band of the
`energy detected by said apparatus.
