Abstract: 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.

Abstract: If a pyroelectric sensor does not detect a heat source after it is determined that the heat source has moved outside a detection region of the pyroelectric sensor, an image processing apparatus is controlled to change from a first power state to a second power state. If the pyroelectric sensor does not detect a heat source before it is determined that the heat source has moved outside the detection region of the pyroelectric sensor, the first power state is stayed in.

Abstract: An infrared detector array or other electrical transducer device comprising an electrically-active film (10) of polymer material is manufactured with a pattern of electrodes (11) embedded at one face of the film (10). The electrodes (11) are formed on a support (4,5) as a photolithographically defined pattern of deposited material. These electrodes (11) are then transferred to the film (10) by depositing the film material on the support (4,5) and over the electrodes (11) and removing the support (4,5) at least at the area of the electrodes (11). The polymer material of the film (10) bonds well to the electrodes (11). In this manner, fine-geometry patterns of thin electrodes (11) can be formed embedded in the face of the film (10) and having reproduceable electrode characteristics for charge detection at the film faces in piezoelectric pyroelectric and ferroelectric devices. The bulk (5) of the support may be of glass dissolvable in HF, and it may have a conductive surface layer (4) which protects the film against the HF and connects the electrodes (11) together when applying an electric field across the film (10) to pole the polymer material, e.g. for a pyroelectric infrared detector.

Abstract: A thermal radiation detection apparatus has an array of pyroelectric detector devices (10) for receiving radiation from a scene whose outputs, e.g. from associated source followers (12) are supplied via a multiplexer (14) in turn to a processing circuit (20) which is responsive to each detector device signal to produce an output which substantially faithfully reproduces the received radiation signal without requiring that a chopper be used. The processing circuit operates with a correction factor to produce an output signal with first and second components proportional respectively to the device signal and its rate of change, the relative proportions of the components being in a ratio according to the device's thermal time constant. Initial device voltage level and the device's electrical time constant effects can be corrected by additional processing in the circuit (20), producing a third component of the output proportional to the integral of the device's output and in a ratio to the first component according to the electrical time constant.

Abstract: The capacitive bolometer comprises a detection capacitor having a first-order phase transition ferroelectric material between two electrodes. The detection capacitor operates during a detection step and a subsequent readout step. During the detection step, a preselected electric field is applied to the detection capacitor to maximize its sensitivity to temperature. A second electric field is applied to the capacitor during the readout step in order to increase responsivity of the detection cell. The detection cells according to the invention can be assembled into disclosed detection arrays.
