摘要： In a detecting device, infrared light is emitted by a first source in a detection target space; second light of a wavelength different from the infrared light is emitted by a second source in a direction different from a direction of the infrared light being emitted by the first source. A reflecting section provided in the direction of the second light being emitted reflects the second light. A light receiver receives infrared light emitted by the first source and reflected by the object, and receives infrared light radiating from the object as a result of the object being irradiated with the infrared light emitted by the first source and being irradiated with the second light emitted by the second source and reflected by the reflecting section. A detector detects the object based on the infrared light received by the light receiver.

摘要： A control system of a detection system for measuring one or more conditions within a predetermined area includes a control unit having at least one processor for implementing an algorithm and a fiber harness having at least one fiber optic cable for transmitting light, the at least one fiber optic cable defining at least one node arranged to measure the one or more conditions. A sensor is operably coupled to the at least one node, wherein the sensor receives scattered light associated with the at least one node and generates signals corresponding to the scattered light. A switch is operably coupled to the sensor and to the control unit. The switch selectively provides signals from the sensor to the control unit for processing to determine at least one of a presence and magnitude of the condition within the predetermined area.

摘要： Systems and methods are provided for device-free motion detection and presence detection within an area of interest. A plurality of nodes, configured to be arranged around the area of interest, form a wireless network. The plurality of nodes transmit wireless signals as radio waves and receive transmitted wireless signals. The received signal strength (RSS) of the transmitted wireless signals between the plurality of nodes are measured and a value is reported. A computing device receives the reported values for the measured RSS and tracks the reported values over time. The computing device processes the reported values using an aggregate disturbance calculation to detect motion and presence within the area of interest. The computing device may notify notification device of a detected disturbance within the area of interest.

摘要： Methods and systems are described for monitoring a monitored space. An example computer-implemented method for monitoring a monitored space includes periodically emitting with an active infrared sensor a modulated infrared signal into a monitored space being monitored by a home automation system, receiving with the active infrared sensor the modulated infrared signals reflected from objects in the monitored space, and determining at least one of whether a number of objects in the monitored space have changed and whether any of the objects are moving.

摘要： A two-dimensional array of magnetomechanical markers is adhered to a continuous web. A magnetizer element is scanned across the web to magnetize the bias elements in a group of the markers with a first polarity, thereby activating the group of markers. The web is then advanced and the magnetizer is scanned across the web in an opposite direction to the previous scan, to magnetize the bias elements of a second group of the markers with a second polarity, thereby activating the second group of markers. The web is slit in a longitudinal direction to produce web-strips each carrying a column of the activated markers. The web-strips are rolled to form marker roll assemblies each having about half the bias elements magnetized with a first polarity and the remaining bias elements magnetized with an opposite polarity. The roll of activated markers forms no more than a minimal "leakage" magnetic field.
