摘要： A handheld radar frequency scanner system for detecting objects concealed on a person, the system includes a radar transmitter coupled to a transmit antenna that is configured and positioned to direct a radar signal at a person, a radar receiver coupled to a receive antenna that is configured to detect a portion of the radar signal reflected by the person, and a processor connected to the radar receiver and operable to process the portions of the radar signals detected by the radar receiver to determine whether the person is carrying a concealed object. The system may produce a real-time alert, such as an audible alert, when a concealed object is detected.

摘要： A real-time learning (RTL) neural network is capable of indicating when an input feature vector is novel with respect to feature vectors contained within its training data set, and is capable of learning to generate a correct response to a new data vector while maintaining correct responses to previously learned data vectors without requiring that the neural network be retrained on the previously learned data. The neural network has a sensor for inputting a feature vector, a first layer and a second layer. The feature vector is supplied to the first layer which may have one or more declared and unused nodes. During training, the input feature vector is clustered to a declared node only if it lies within a hypervolume defined by the declared node's automatically selectable reject radius, else the input feature vector is clustered to an unused node. Clustering in overlapping hypervolumes is determined by a decision surface. During testing of the RTL network, the same strategy is applied to cluster an input feature vector to declared (existing) nodes. If clustering occurs, then a classification signal corresponding to the node is generated. However, if the input feature vector is not clustered to a declared node, then the second layer outputs a signal indicating novelty. The RTL neural network is used in a perceptive system which alternatively selects the RTL network novelty output or the output of a classifier trained on historical target data if the input vector is a subset of the historical target data.

摘要： A device includes a sensing element configured to produce a representation of an object in a space near the sensing element, an electronic storage comprising multiple representations, each representation being associated with a particular object, a communications interface, and a processor operable to receive the representation of the object in the space from the sensing element, compare the representation of the object in the space to the multiple representations stored in the electronic storage, determine that the representation of the object in the space is different from all of the multiple representations based on the comparison, identify the representation as a new representation based on the determination, and cause the new representation to be available to a data site through the communications interface. The device also may obtain a new representation from the data site.

摘要： A concealed object detection system for detecting objects concealed on a person includes radar transponders that are each configured and positioned to direct a radar signal at a person and to detect a portion of the radar signal reflected by the person. A processor connected to the radar transponders processes the portions of the radar signals detected by the radar transponders to determine whether the person is carrying a concealed object. The system may produce a real-time alert, such as an audible alert, when a concealed object is detected.
