Embodiment Construction

[0037] FIG. 1 is a schematic diagram of a processor for a break-in and vehicle alarm system in a preferred embodiment of the present invention. The invention comprises a processor 1 with sufficient internal non-volatile and volatile memory to hold and use the desired software algorithms. A precision oscillator of a frequency is chosen such that the ports of processor 1 are sampled with sufficient precision and software algorithms are used at the desired rate. For battery operation and lower accuracy, Oscillator 2 can be selected at a lower frequency.

[0038] Processor 1 has a plurality of ports for receiving and transmitting information. Ports 3 and 4 and 5 and 6 include analog to digital converters and may receive analog signals, for example from infrasonic signal detection circuits. Ports 7 and 8 and 9 can receive and transmit digital signals, for example with various associated devices. Port 10 is used to inform processor 1 when detection processing is running and to pr...

Abstract

Present day intrusion detection systems frequently cause false alarms by mistaking occupants as intruders, and it is desirable to reduce such false alarms. This invention comprises a processor that employs various software algorithms. The processor receives signals over temporal periods and software algorithms statistically discern various activities, thereby reducing false alarms and detection failures. The software algorithms are adaptive to the level of detected activity such that a rate of false alarms may be predetermined. As such, the processor and software algorithms comprise an artificial intelligence system. This artificial intelligence system may be employed in intruder and vehicle alarm systems composed of a multiplicity of detectors and within such detectors. A second aspect of this invention is an improved infrasound detection method that may be employed in such artificial intelligence.

Description

technical field [0001] The present invention relates to trespasser and vehicle alarm systems and detectors. In particular, the present invention relates to the use of processors and software algorithms including artificial intelligence systems in combination with detectors in trespasser and vehicle alarm systems to reduce false alarms and detection failures. More particularly, the present invention relates to the combined use of artificial intelligence and infrasound detection in trespasser and vehicle alarm systems and detectors. Background technique [0002] Alarm systems balance the need to minimize false alarms with the need to minimize detection failures. It is desirable to minimize false alarms to reduce associated annoyance and expense, and to minimize detection failures to maintain the deterrent and detection value of the alarm system. [0003] Alarm detection technologies include various switches, motion detectors, glass break detectors, vibration detectors, infra...
