Abstract: To make the settings for an X-ray installation, so that the images that it reveals have the greatest possible contrast, a measurement is made of a mean equivalent thickness of the body of a patient being examined from a test image. However, as a preliminary, the test image is rid of those pixels for which it is known, a priori, that their significance does not comprise any interesting gray levels. The dynamic range of the image can be set objectively by choosing the thickness threshold and the equivalent mean thickness as a given proportion of the dynamic range. Preferably, the computation and the setting are done on the fly, in real time after the acquisition of the test image.

Abstract: Data is dynamically routed between first and second locations. An attempt failure ratio is obtained for each of several data paths capable of providing a data link between the first and second locations, where such ratio represents a proportion of failed linkages by the data path to all attempted linkages by the data path between the first and second locations. A revenue value is also obtained for each data path, where such value represents an amount per unit generated by a successful linkage by the data path between the first and second locations. A comparative income value is then computed for each data path, where such value is a product of the attempt failure ratio for the data path and the revenue value for the data path. Routing information is then selected for routing the data between the first and second locations based on the comparative income value for each data path. The routing information may be employed to route the data by way of at least one of the data paths.

Abstract: A method is set forth of controlling an acoustic echo canceller at the output of a beamformer in an audio conferencing device. Information is saved to, and retrieved from, memory that characterizes each of a finite number of look directions, or regions of focus, covering the entire spatial span of the conferencing device. Each time a change occurs from a first look direction to a second look direction, information relating to the workspace captured by the acoustic echo canceller is saved for the first look direction, and previously saved information for the second look direction is retrieved from memory. The acoustic echo cancellation then takes place for the second look direction with the retrieved information.

Abstract: Long distance telephone connections must commonly employ echo cancellers to eliminate irritating echo. The normal practice is to additionally employ non-linear processors (NLPs) as an integral component of an echo canceller in order to eliminate small residual echo which remains after initial echo cancellation. While such devices do indeed remove remaining residual echo, they also may introduce additional problems, such as suppression of the background signal. However, in some cases there is no need to deploy a potentially problematic non-linear processor. If the overall route delay of the telephone connection is not excessive, the participants do not notice the residual echo. Therefore, a determination is made of the end to end delay of the overall telephone connection. If the determined delay is not excessive, non-linear processing is not applied or is applied less aggressively. This results in a clearer telephone call, free from non-linear processor problems.

Abstract: A method of determining when to save default coefficients in an echo canceller so as to ensure that the capture of coefficients that correspond to the best possible echo cancellation in a current condition. Coefficients are saved at varying times depending on the amount of echo removed by the echo canceller. More particularly, the present method involves constantly monitoring the error signal to the echo canceller and comparing it with the error signal that would be obtained if default coefficients were to be used instead of the current coefficients. This ensures that the default coefficients are upgraded each time the current set of coefficients is better than the saved default coefficients.

Abstract: In a method of determining a pair of numbers comprising a first number and a second number, in which the first number may be a first key and the second number may be a second key of an encryption system and the second number is the multiplicative inverse with respect to a modulus of the first number, said modulus being equal to the product of a first prime number and a second prime number, the first number is selected first. Thereafter, a first sub-number for the second number is computed as a multiplicative inverse of the first number with respect to a first sub-modulus that is equal to the first prime number minus 1 divided by the greatest common divisor of the first prime number minus 1 and the second prime number minus 1. Then, a second sub-number for the second number is computed as multiplicative inverse of the first number with respect to a second sub-modulus that is equal to the second prime number minus 1, with said first sub-modulus and said second sub-modulus being relatively prime.

Abstract: The present invention provides a method for protecting public key schemes from timing, power and fault attacks. In general, this is accomplished by implementing critical operations using “branchless” or fixed execution path routines whereby the execution path does not vary in any manner that can reveal new information about the secret key during subsequent operations. More particularly, the present invention provides a modular exponentiation algorithm without any redundant computation so that it can protect the secret key from C safe error attacks. The improved method also provides an algorithm that doesn't have a store operation with non-certain destination so that the secret key is immune from M safe error attacks.

Abstract: A stream-based cipher may be used to bitstream a data file into multiple files. Each file is incomplete and therefore unreadable without knowing the other files that must be used to reconstruct the original file. A central registry may be maintained which indicates which files are together. Files may be reconstructed by brute force computing once all the files are retrieved, eliminating the need for any indication of how to reassemble the files to be transmitted. By using such a system, authorities (either governmental or corporate) are prevented from casually examining a file for content or even for file format. The files will simply appear as random data.

Abstract: In a broadcasting signal output apparatus and a method, an OSD processing unit produces a display-lock message if a display of contents is not permitted. A control unit determines whether the decoded video signal includes a copy protection signal for preventing the video signal from being reproduced, and if so, the control unit requests and receives a certification signal from the display device to determine whether the video signal can be transmitted to the display device through the video output terminal. The control unit then determines whether the certification signal corresponds with the reproduction preventing signal, and if it does not, prevents the decoded video and audio signal from being outputted, and controls the OSD processing unit so that the display-lock message is output to the display device (e.g., screen), so that the user knows when the currently received broadcasting signal is not displayed due to copy protection signal.

The system allows for the inclusion of different data elements with or within a single version of the software program. The different data elements are encrypted for different license keys to allow for different license options and corresponding levels of control and flexibility in the delivery of the software program.
