  • Patent number: 11763650
    Abstract: Managing foreign RFID tags within a secured area involves use of a first RFID portal system to read tag data from an RFID tag present within a first portal zone. A processing device associated with the first RFID portal system is used to determine whether the RFID tag is entering the secured area. The determination is based on an evaluation of a direction of travel of the RFID tag through the first portal zone. Responsive to determining that the RFID tag is in fact entering the secured area, one or more operations are performed to cause a first tag value corresponding to the tag data to be added into a safe to exit (STE) list.

  • Patent number: 11619738
    Abstract: A wireless dual technology displacement sensor (“displacement sensor system”) and method are disclosed. The displacement sensor system includes an analyzing sensor for determining a range to a measuring point and a trigger sensor for activating the analyzing sensor. The trigger sensor is an accelerometer or an optical proximity sensor (OPS), in examples. The analyzing sensor is preferably a time of flight range sensor. When installed as part of a door system having a door and door frame, for example, the trigger sensor detects movement of the door, and activates the analyzing sensor in response. The analyzing sensor then determines the range to the measuring point, such as the door frame. This two sensor system can be thus used to prevent the high current consumption of existing displacement sensor systems.

  • Patent number: 11604050
    Abstract: After determining that a gunshot has been fired, particularly indoors, the method of the invention is employed to determining the number of gunshots fired by analyzing consecutive windows of time over a certain time period. That is, after it is determined that a gun has been fired, the method is employed to identify that the gun is an automatic or rapid fire weapon by quickly counting the number of rounds shot over short periods of time. This information can be used to provide shooting details, both in connection with notifying emergency personnel and enabling the personnel to assess details of the shooting incident.

  • Patent number: 11562634
    Abstract: A passive infrared motion detector discriminates between the motion of humans and pets in a premises. The motion detector includes an infrared sensor and a mirror for focusing infrared radiation from distinct fields of view. In one embodiment, a mask prevents infrared radiation from reaching the infrared sensor, and cut away regions on the surface of the mask allow selective passage of infrared radiation to the infrared sensor. In an alternative embodiment, the cylindrical mirror elements includes reflective and unreflective regions, which allow selective passage of infrared radiation to the infrared sensor. The cut away regions and the reflective regions are elongated to correspond to the shape of standing humans. As a result, the infrared radiation from animals only partially reaches the infrared sensor.

  • Patent number: 11532226
    Abstract: A system and method for acoustically detecting the firing of gunshots indoors employs multiple microphones (15, 20) which are utilized individually and in combination to detect sounds inside a building or other structure and, upon sensing a loud impulsive sound which is indicative of a gunshot, processing signals from both microphones (15, 20) to determine if the sound is that of a gunshot. The system and method relies on the acoustic signature of the noise as collected, with the acoustic signature being analyzed to arrive at values which are then compared to adjustable levels that signify a gunshot.
