Abstract: A predictive model system is used to detect telecommunications fraud. Call records (CDRs) provided by telephone companies are evaluated against specified rules. If one or more rules are matched, the system generates an alert. Pending alerts for a customer form a case, describing the caller's calling patterns. A predictive model determines a score that is predictive of the likelihood that the call involved fraud. Cases are queued for examination by analysts.

Abstract: A spatial tracking system tracks movements of sources of radiated energy. In the one embodiment of the invention, three sensor sets are included each containing a pair of sensors. Movements of a single radiation source with a radially symmetric emission pattern is tracked in up to six dimensions; X, Y, Z, yaw, pitch and radiation intensity. Sources with different radiation ranges or types are tracked at the same time using sensors tuned to the different radiation ranges or types. The sensor sets may include more than two sensors which increases the spatial range monitored and increases tracking accuracy and optionally include sensors tuned to different radiation sources, such as light of different wavelengths. Individual sensors can be included with the sensor sets which increase the rotational range of the system beyond the range for translation tracking.

Abstract: A micromechanical component comprises a frame layer and an oscillating body which, with the aid of a suspension means, is supported in an opening penetrating the frame layer, in such a way that the oscillating body is adapted to be pivoted about an axis of oscillation vertically to the frame layer plane. At least one oscillating-body lateral surface, which extends substantially at right angles to the frame layer plane, is arranged in relation to at least one inner lateral surface of the opening in such a way that a capacitance formed therebetween is varied by an oscillation of the oscillating body in such a way that an oscillation of the oscillating body about the axis of oscillation can be generated by periodically varying a voltage applied between the frame layer and the oscillating body.

Abstract: A method and system for producing multiple copies of an executable software object, in which a copy is functionally identical to all other copies while being structurally unique, alter the source code according to parameters specified by a seed and a set of preferences. High-level source code is translated to assembly code. Selected procedures from the assembly code are blended to form larger procedures functionally equivalent to the original procedures. Instructions within procedures are reshuffled, while the original flow of execution is conserved. Dummy opcodes are interspersed with executable instructions. The resulting modified code is translated to object code and an executable object is constructed. The invention is also embodied as a computer readable program product on a computer readable medium. Each copy bears a unique fingerprint that allows the producer of the product to exercise control over the use of the software product and prevent unauthorized use and copying.

Abstract: A non-invasive system for characterizing and classifying the state and structure of a tissue sample operates on a near infrared absorbance spectrum of in vivo tissue. A method that uses near-infrared spectral measurements to characterize and classify the state and structure of tissue sampled based on absorbance features related to fat in adipose tissue is provided. Also provided is a method of estimating skin fold thickness. The approach provides information about sources of tissue variability and is therefore useful for establishing the general category of the tissue structure. Categorization of subjects on the basis of the determination is suitable for further spectral analysis and the measurement of biological and chemical compounds, such as blood analytes. The invention further provides a method of estimating percent body fat based on a skin fold thickness estimate.

Abstract: An embedded data acquisition and control system for a precision instruments, such as a non-invasive glucose prediction instrument is disclosed. One feature of the invention provides synchronization of stepper motor position and analog-to-digital converters. An embedded controller is provided that controls the stepper motor driver directly to minimize the wavelength shift error due to the asynchronous condition. The controller synchronizes the event of reading the A/D converters with each stepper motor position. Because the stepper motor controls the wavelength of the monochromator optical output, the net result is that each A/D conversion recorded by the embedded controller is precisely tracked to a specific wavelength. Another feature of the invention provides closed loop motor position control for enhanced system performance. In the closed loop system, a position encoder is coupled to the stepper motor shaft.

Abstract: In a coding method and a coder for introducing a non-audible data signal into an audio signal, the audio signal is first transformed to a spectral range and the masking threshold of the audio signal is determined. A pseudo-noise signal and a data signal are provided and multiplied with each other so a to provide a frequency-spread data signal. The spread data signal is weighted with the masking threshold, and thereafter the audio signal and the weighted data signal are superimposed. In a method and a decoder for decoding a data signal introduced into an audio signal in non-audible manner, the audio signal is first sampled and thereafter the sampled audio signal is filtered in non-recursive manner. The filtered audio signal is subsequently compared to a threshold value so as to retrieve the data signal.

Abstract: The invention provides an improved method and system for presenting television signals, including anti-aliasing of text with respect to a background. The background color is determined relatively locally for each element to be anti-aliased, and text or other graphics overlaid on that background are anti-aliased with respect to each relatively local background color. Also, anti-aliasing can be applied to blur text and graphics more vertically than horizontally to reduce flicker, and to blur chrominance more than luminance to reduce cross-chrominance artifacts resulting from Y/C separation. Similar techniques may be used for filtering images in addition to anti-aliasing text characters.

Abstract: An enhanced swim fin is provided comprising a flipper blade having an increased effective surface area during movement in a first direction, and a decreased effective surface area during movement in a second direction. The swim fin preferably comprises a staged opening during movement in the first direction, in which the opened flipper blade provides increased flexion as the effective surface area is increased. The swim fin preferably comprises a staged closing during movement in the second direction, in which the opened flipper blade provides decreased flexion as the effective surface area is decreased. In some embodiments of the staged swim fin, a central hinge, generally located longitudinally along the blade on the fin, provides staged opening and flexion. Various embodiments provide fin opening and closing for either forward or backward kicks. The enhanced swim fin is typically attached to a foot, such as for performance, for training, or for physical therapy.

Abstract: A system and method provide the creation and operation of remote real-time data monitoring and control systems. Such applications include a communications gateway coupled to real-time devices. The communications gateway transforms the real time data collected from disparate and non-interoperable systems in a single common data format. The communications gateway provides an object server with a list of the real-time devices to which the communications gateway is connected, and their attributes. The object server publishes this list. Subscribers can access this list, and request subscriptions to specific attributes of certain devices. The object server creates a data object corresponding to the requested information. A subscriber includes a service agent which accesses the object server. In addition, a subscriber may also comprise presentation cells, which provide a representation and mapping of data objects and hence underlying devices and systems, to allow a user to manage and control such systems.

Abstract: A two-step motion prediction for MPEG-2 interpolation case-D will yield visual artifacts if not corrected. An improved MPEG-2 decoder includes a logic gate, multiplexer, and adder. When both the horizontal (h0) and vertical (h1) motion vector components require a half pixel interpolation (case-D), the multiplexer forwards the constant minus three to the adder, otherwise a constant zero is used. Such adder modifies the DC coefficient input to the inverse discrete cosine transformer to include a correction term for the predicted pixels calculated by a two-step predictor. A correction value of −0.375 is evenly distributed over all sixty-four resulting spatial coefficients during the inverse discrete cosine transform. This results statistically in a slightly brighter set of correction terms. Such offsets result in a slightly darker prediction that is formed by the two-step predictor. The output frames are statistically correct images.
