A piracy protection system incorporates tamper detection capabilities into a protected copy of an application by disassembling a statically linked binary of the application, modifying some of the instructions in the application, and then rewriting all of the modified and unmodified instructions to a new executable file, a protected copy. The piracy protection system comprises an offline tamper detection technique in which the software itself detects the tampering and causes the program to fail, therefore protecting itself from malicious attacks. The system further comprises a dynamic software-watermarking process that incorporates code obfuscation to prevent reverse engineering.

A speech recognition system for transforming an acoustic signal into a stream of phonetic estimates includes a frequency analyzer for generating a short-time frequency representation of the acoustic signal. A novelty processor separates background components of the representation from region of interest components of the representation. The output of the novelty processor includes the region of interest components of the representation according to the novelty parameters. An attention processor produces a gating signal as a function of the novelty output according to attention parameters. A coincidence processor produces information regarding co-occurrences between samples of the novelty output over time and frequency. The coincidence processor selectively gates the coincidence output as a function of the gating signal according to one or more coincidence parameters. A vector pattern recognizer and a probability processor receives the gated coincidence output and produces a phonetic estimate stream representative of acoustic signal.

The monitoring method includes: detecting a stabilized condition; determining an average value of the control current during the detecting the stabilized condition; and comparing the average value with a predetermined threshold.

A sensor system and a joystick including the sensor system. The sensor system comprises a magnetic field sensor, and first and second magnetic sources. The first magnetic source is rotatable relative to a sensitive surface of the sensor and generates a first magnetic field contribution of at least quadrupolar order. The second magnetic source is pivotable with respect to the sensitive surface and generates a second magnetic field contribution. The sensor is configured for detecting at least an in-plane component of a superimposition field of the first and second magnetic contributions at a plurality of lateral measurement locations on the sensitive surface, obtaining measurements, and determining a rotation angle for the first source from the field gradient measurements and two angular directions for the second source from the field mean measurements. Lateral measurement locations are arranged into two pairs of diametrically opposite measurement locations with respect to the sensitive surface.

Methods for generating a customized spectral profile, which can be used to generate a corresponding filter, lamp or other type of illuminant. A trial spectrum is generated. A reference spectrum is determined or otherwise obtained. A SOURCE spectrum is determined or otherwise obtained. One or more optical indices are calculated using the trial spectrum and one or more of the optical indices are optimized by varying the trial spectrum to generate the customized spectral profile. A radiation force parameter can be used to minimize unsafe build-up of light in spectral regions. Adaptations of color rendering parameters can be used in the optimization process. Smoothing parameters can be used to enable easier design of filter structures. A reflectance camera can be used to measure reflectance data at one or more pixels of a digital representation of an object to be illuminated.

A fuel vessel assembly for a fuel cell-powered vehicle and a method of increasing the structural rigidity of a fuel cell-powered vehicle. A vessel for storage of hydrogen or related fuel cell-compatible fuel is rigidly attachable to a vehicular frame or related load-bearing structure through one or more shells that extend from the vessel. Loads imparted to one or more of the shell, vessel frame are transmitted between them through the connection between the assembly and the frame such that a load-bearing capability inherent in the frame is enhanced by the assembly.

A blind modulation classification apparatus in a satellite communication system improves performance in non-ideal communication environment having frequency error and phase error, by reducing computational burden of test statistic and possibility of numerical error of hardware, with computation of likelihood for each stage independently. The blind modulation classification apparatus includes a plurality of likelihood computing units, each for computing a likelihood value of a received baseband signal for corresponding one of a plurality of modulation schemes; a maximum selecting and setting units for selecting the maximum among the calculated likelihood values and setting a flag corresponding to the maximum to ‘1’ and the other flags to ‘0’; a plurality of flag summing-up units for summing up the flags of the plurality of the modulation schemes; and a modulation scheme selecting unit for selecting the maximum among the summed-up values and selecting the modulation scheme corresponding to the selected value.

A computer-assisted design method for a second three-dimensional object from a first three dimensional object known only by its boundary surfaces, through a surface model of the B-Rep type, of the planar, cylindrical, cone, sphere, or toroid type, excluding free forms in defining the boundary of the object. The first object is broken down into a set of simple volume primitives. The first object is associated with a construction graph defined from these volume primitives and a set of geometric parameters for using these volume primitives in the specific case of that first object. The construction graph enables a compact description of all of the construction alternatives of the object through Boolean combinations of these primitives. The second object is generated as an alternative of the first object according to that construction graph, by modifying some of these parameters.

For the purpose of providing sector-address information on optical disks, a robust header is realized by utilizing a very simple encoding method that allows asynchronous reading. In order to provide robustness and reliability, the header uses a biphase data format to encode addressing information. The embossed header is further configured with redundant address-fields in a checkerboard pattern between adjacent tracks, in order to provide robustness for media-contamination. Each address-field starts with a unique address-mark and ends with parity-check information to provide reliable error-detection. The entire header can be decoded without the need for a slice-level, thus making it very tolerant to amplitude-variations and DC-offset variations. By combining these characteristics, a header is achieved which is reliable and inherently resistant to failures in providing sector-address information on optical disks.

An adjustable motorcycle headlight with multiple degrees of freedom enables the rider to aim the light where it is needed, as well as facilitating the factory assembly process by enabling fine adjustment after the headlight is mounted. The motorcycle headlight is attached to the frame via a ball and socket structure cooperatively coupled to at least one positioning arm provided in tandem with the ball and socket structure for accommodating and stabilizing the movement of the ball and socket joint and locking same in position. The positioning arm includes a series of straight segments rotatably attached to one another via adjusters which can be loosened to enable adjustment, and tightened to affix the positioning arm into place. The combination of the ball and socket joint with a pair of positioning arms also provides a stable, robust three-point attachment mount for the headlight.
