Abstract: A method and system of intrusion detection, which includes displaying sensing device output data as an image of a field of view of a sensing device. Through interaction with a GUI: a user input defines an image detection area in relation to the image of the field of view, the image detection area being correlated to a detection area to be monitored for intrusion detection. A user input defining a detection vector in the image detection area is received, specifying a predetermined minimum displacement and displacement direction in the field of view. A graphical representation of the vector may be displayed on the image detection area. A target object is detected and tracked through the detection area and it is determined whether the progressive displacement of the target object has a component exceeding the minimum displacement in the direction of the vector.

Abstract: An intrusion detection system comprises at least two detectors. Each detector is configured to produce a detection output. At least one information module is configured to produce metadata that relates to the performance of one or more of the at least two detectors. An analysis module is configured to produce a combined alarm signal. The combined alarm signal is a function of the plurality of detection outputs from the at least two detectors and the metadata. The metadata may include information relating to adverse conditions that reduce detection performance of one or more of the detectors. The at least two detectors preferably include at least one video motion detector and a passive infrared detector.

Abstract: An Electret Condenser Microphone (ECM) motor apparatus includes a diaphragm ring support structure, a charge plate, and at least one stitch. The diaphragm ring support structure defines an opening there through. The charge plate is disposed within the opening. The at least one stitch is coupled to the diaphragm ring support structure to the charge plate. The diaphragm is disposed adjacent to and in a generally parallel relationship to the charge plate. The stitch is configured to hold the charge plate and the diaphragm ring, and the stitch is configured to maintain a constant or nearly constant distance between the charge plate and the diaphragm in the absence of sound energy.

Abstract: A method and system of intrusion detection, which includes displaying sensing device output data as one or more images of a field of view of a sensing device (14.1, 14.2, 14.3). Through interaction with a graphical user interface: a user input to define and display an image detection area in relation to the one or more images of the field of view is received, wherein the image detection area is correlated to a detection area to be monitored by the sensing device (14.1, 14.2, 14.3) for intrusion detection. One or more user inputs that define a detection vector in the image detection area are received, the detection vector specifying a predetermined minimum displacement and direction of displacement in the field of view to be monitored. A graphical representation of the detection vector may be displayed on the image detection area.

Abstract: The invention relates to a particle detector, systems, and methods for detecting the presence of particles in a volume of air, most particularly it relates to detection systems and methods that use multiple modes of detection to detect the presence of particles. Preferably the particles being detected are particles that indicate an actual or incipient fire, or pyrolysis, such as smoke.

Abstract: An apparatus includes a top assembly, a bottom assembly, and a diaphragm assembly. The bottom assembly is coupled to the top assembly to form an overall assembly. The diaphragm assembly includes a ring and a diaphragm flexible member that is attached to the ring. The ring forms an opening and at least one strengthening member is disposed at least partially across the opening. The at least one strengthening member is configured to provide strength and maintain a predetermined compliance of the diaphragm flexible member.

Abstract: The invention provides a method of targeting a drug to areas of hypoxic and/or ischemic tissue within the body in which the desired drug species is linked to a non-cytotoxic bioreductive carrier. Also provided by the invention are novel bioreductive conjugates comprising a non-cytotoxic bioreductive moiety with linked-thereto at least one therapeutic agent. The compounds of the invention are particularly suitable for the treatment of rheumatoid arthritis and other arthritic conditions, diabetes, atherosclerosis, stroke, sepsis, Alzheimer's disease and other neurological disorders, cancer, kidney disease, digestive diseases, liver disease, chronic periodontitis or ischemia following tissue transplantation.

Abstract: Method and apparatus for detecting change of an object state from an initial state where the object is displayed in a plurality of sequential images. The system involves comparing a measure over a predetermined portion of each of the images corresponding to an object's initial state with a reference value of the measure computed when the object is in the initial state to generate a comparison value for each of the images and then generating a signal indicating that the object state has changed when a predetermined number of the comparison values generated for each of the images do not meet a predetermined criterion.
