Abstract: The prevention of counterfeiting labels for various products is addressed by introducing counterfeit-proof labels having an optically concealed, invisible universal product code.The label is printed on a high-resolution micro optic photo chromogenic material. The color bars of the code are optically split and compressed in high resolution image elements and arranged at the pre-calculated optical blind angles in relation to the optical center of the lenticule and the viewing distance of the label, and due to the optical effect of the micro lenticule, the complete color product code is not visible when viewing at a normal viewing distance.The camera of a mobile phone photographs the label at a close-up distance, with the lens of the camera regrouping the split image elements of all the color bars to reconstruct the product code that will be displayed on the screen of the mobile phone.

Abstract: An alignment process is applied to each sensor of an array of three axis magnetic sensors to electronically align the three axes of each sensor after the array has been deployed. The alignment process compensates for each sensor not being aligned perfectly with the earth's N-S, E-W and vertical magnetic field components. A field registration process is applied to each sensor of the array that uses a dipole moment detection and localization process and the alignment process combined with a known calibrated dipole source to define the shape of the array. The present invention improves the performance of the array of sensors in detecting magnetic anomalies by digitally compensating for sensor-to-sensor nonalignment and magnetic interferers within interfering range. The alignment process electronically aligns the three axes of each of the sensors to gain maximum performance from the sensor array. Using digital signal processing techniques reduces the physical deployment requirements on the sensors and their relative positions. The alignment process allows the use of three axis vector magnetometers in a distributed field with out having to lay each sensor in perfect alignment with the earth's three magnetic axis. This simplifies the deployment requirements and allows for maximizing the system performance.

Abstract: A filmless 3D printing method for producing 3D photographs on lenticular print material. The 3D photograph is composed of a series of 2D images of a scene acquired by a video camera and displayed on a video monitor screen. During printing, the projection lens and the print material are moved to different positions to change the projection angles and fill the lenticules with compressed images. While the video camera is moved in relation to the scene to acquire 2D images, it aims at the key subject of the scene at all times so that the location of key subject image on the images displayed on the screen is always the same. Thus, the 2D images exposed on the print material are automatically aligned. The 2D images of a scene at different viewing angles can also be generated on a computer.

Abstract: An automatic detection apparatus and method applies the Short and Toomey algorithmic processing procedure to a frequency and beam direction windowed and time segmented set of Fast Fourier Transform (FFT) magnitude detected data, comprising time, frequency and beam direction data, to determine the presence or absence of narrowband lines indicative of target tracks. This is achieved by storing the time, frequency and beam direction data, and then processing this data using a predetermined three-dimensional maximum a posteriori procedure whereby individual target tracks associated with each beam direction are concurrently processed, and whereby transitions are made between adjacent beam directions in order to process target tracks having a maximum signal to noise ratio to provide for detection of a target. An output target track is generated by combining the high signal to noise ratio portions of the processed individual target tracks into a single output target track. The present invention extends the tracking capabilities that are obtained using the Short and Toomey processing procedure from two dimensions to three dimensions, and this added dimension provides spatial tracking in addition to spectral tracking. The spatial tracking is performed concurrently with the spectral tracking in an array processor.

Abstract: An active adaptive noise canceller that does not require a training mode and operates over an extended noise bandwidth. The canceller partitions the noise bandwidth into frequency sub-bands, and multiple adaptive filter channels are employed, one for each sub-band, to cancel noise energy in the respective sub-bands. Each channel includes bandpass filters to restrict the channel to operation over only the particular sub-band, and delays are inserted in the operation of the filter weight updating. Because each channel is stable over its sub-band, the canceller operates over the extended noise bandwidth of all the sub-bands.

Abstract: A synthetic array comprising a moving magnetic sensor that provides a signal representative of an array of magnetic sensors is coupled to a digital signal processor is used to break a magnetic dipole field into its components, and a magnetic signature of the present magnetic field is created. Predicted dipole signatures are precomputed for multiple magnetic orientations of the dipole at each of a plurality of range locations, expressed in terms of Anderson functions, which are a set of equations that decompose the magnetic field in each of the magnetic response locations, and are stored in a lookup table for reference. Input data measured by the moving synthetic array are processed and each magnetic value is predicted to process against background noise. A long term time average consistent with the relative motion of the dipole is computed using bandpass filtering of the signals from the synthetic array. The bandpass filtered data is used to update the predicted data so that anomalies and other non-dipole data is removed from the signals that are processed. The data are then expressed in terms of Anderson functions. The data are matched faltered, wherein it is correlated with the stored precomputed predicted dipole signatures. The correlation yields a set of values that is then thresholded. If a dipole is present at any of the locations, then the correlated normalized value computed as stated above will be higher than the chosen threshold. The dipole locations that are above the threshold are then displayed on a monitor showing the relative location and dipole orientation.

Abstract: A dipole moment detection and localization process and apparatus in which the processing is applied to a single linear array adapted to sense magnetic dipoles, and wherein data from the sensors are processed as if it were derived from sets of subarrays of sensors. The apparatus comprises a linear sensor array whose output is processed by separate dipole moment detection and location processors, or a single processor that provides for parallel processing operation. Data from the plurality of subarrays of sensors are processed in terms of Anderson functions and are correlated. The individual outputs of each processor, or parallel processing portion, is coupled to a multiplier that is adapted to correlate the signals. The dot product of these two correlated output signals is then formed to yield data that is thresholded and displayed.

Abstract: The prevention of counterfeiting labels for various products is addressed by introducing counterfeit proof labels having an optically concealed, invisible progressive shifting security safety symbols for quick identification. The label is printed on a high-resolution micro-optic photo chromogenic material. A multiple number of images of an optically compressed security safety symbol are printed on the focal plane along the linear optical center of each micro-lenticule across the entire area or a small portion of the label. Due to the optical effect of the micro-optic, the complete security safety symbol is not clearly visible at normal viewing distance. When viewing the label directly or using the camera of a mobile phone at a close-up distance or slightly bending the label, each micro-lenticule within the viewing angle projects and magnifies a small section of the compressed security safety symbol on the surface of the micro-lenticules to reassemble the complete original image of the security safety symbol for identification.The image elements that compose the compressed security safety symbols under each micro-lenticules are printed at the approximately same location on the focal plane of each micro-lenticule in relation to the linear optical center of the micro-lenticule. Therefore the same and complete reassembled image of the security safety symbol can be seen from any location of the label for quick identification. The complete reassembled image of the security safety symbol is progressive shifting following a moving viewpoint for quick and accurate identification.The color photo of the reassembled security safety symbol can be sent by a mobile phone installed with a related software to an Anti-Counterfeiting Control Center for computer matching and verification and the consumer will be advised of the result in a matter of seconds

Abstract: An active adaptive noise canceller that inserts delays into the weight update logic of an adaptive filter to keep the filter stable. The noise and residual noise are sensed and the respective sensor signals are digitized at a given sample rate for processing in the adaptive filter. To eliminate the need for high sample rates while maintaining flexibility in the frequency regions over which the adaptive filter is stable, the delay introduced into the weight update logic is a non-integer multiple of the sample period. The non-integer sample delay is obtained by a sample interpolation and decimation procedure.
