摘要： A motion sensor has at least two tiers of monitored volumes that are offset from each other. Electromagnetic radiation, such as infrared light, is directed from the monitored volumes onto at least two sets of detector elements having separate outputs on a pyroelectric substrate of an infrared detector. As a warm object, such as a human or an animal, moves through the monitored volumes, the warmth from the object causes the voltage on the outputs of the infrared detector to change. The resultant waveforms are compared and if the two waveforms have a phase relationship corresponding to a critical phase angle that is based on the pitch of the monitored volumes and the offset between the tiers of monitored volumes, an animal-immune motion indication is generated.

摘要： A passive infrared intrusion detection device uses a dual element pyroelectric detector and a housing for surrounding and containing the dual element pyroelectric detector. The housing has a plurality of Fresnel lens elements for gathering infrared radiation from a "look down" volume of space and for focusing the gathered infrared radiation onto the pyroelectric detector. A mask positioned between the plurality of Fresnel lens elements and the detector partially occludes the gathered infrared radiation from the Fresnel lens elements to one of the elements of the dual element pyroelectric detector creating an imbalance in the signal thereby preventing common mode rejection.

摘要： The intrusion detection system of the invention, in which three pyroelectric detectors are disposed in line with a interval and an adjoining two of the three pyroelectric detectors are electrically connected to cancel electrical charges generated by each pyroelectric detector, detects intrusion of an infrared ray radiating object such as a human body for example by output signals outputted from the adjoining two and the other of the three pyroelectric detectors or by output signals outputted from the pyroelectric detector disposed at the center and adjoining one and output signals outputted from the one disposed at the center and adjoining another one of these pyroelectric detectors, so that precise and secure intrusion detection is possible by reducing erroneous signals generated by those pyroelectric detectors due to variation of the atmospheric temperature and the like.

摘要： A passive infrared detection system embodies a new three-element, single-channel, pyroelectric detector. For a given amount of motion by a target in a region under surveillance, the detector provides more complex signature information than conventional two-element detectors, thereby allowing the target to be more readily distinguished from spurious environmental or background sources. Owing to the geometry of the detector electrodes, the false-alarming effects produced by spurious stimuli common to all detector elements are reduced. The detector is particularly adapted for use in infrared detection systems of the type which use pulse-counting techniques to distinguish targets of interest from non-targets.
