Verification support apparatus, verification support method, and computer product
The circuit volume of a system under design is reduced by a circuit conversion involving consolidation (sharing) of common parts in the system by a representative part. The design data of the system post-conversion is used to verify operation of the system. However, the verification results for the system post-conversion express signals (e.g., signal X) of plural modules (e.g., modules a to c) as one signal waveform thereby making debugging difficult when a bug is found. Given this situation, from the verification results of the system post-conversion, signal-generation-use data is generated for generating the signal waveforms (here, respective signal waveforms for the modules a to c) of the system before conversion. After verification is complete, a signal waveform for each of the modules a to c is generated using the verification results for the system under design and the signal-generation-use data. |

Method and apparatus for testing delay faults
An apparatus or method for testing of a SOC processor device may minimize interference that is caused by interfacing a comparatively low-speed testing device with the high-speed processor during testing. Implementations may gate the input clock signal at the clock input to each domain of the SOC processor device rather than at the output of the PLL clock.

Echo canceler and echo canceling method
An echo canceler has an adaptive filter that generates an echo replica signal from a far-end signal. The filter coefficients of the adaptive filter are updated according to a residual error signal, which is obtained by subtracting the echo replica signal from a near-end signal to cancel echo. A background noise estimator estimates the near-end background noise power level from the residual error signal. A step size calculator uses the estimated near-end background noise power in determining the step size of the adaptive updating of the filter coefficients. When the estimated near-end background noise level is high, a small step size is used, which improves echo cancellation under these conditions. When the estimated near-end background noise level is low, a larger step size is used to permit rapid convergence of the filter coefficients. |

Polarization preserving front projection screen material
Polarization preserving front projection screens and diffusers provide optimum polarization preservation for stereoscopic 3D viewing, as well as improved light control for enhanced brightness, uniformity, and contrast for both 2D and 3D systems. Generally, the disclosed screens direct light from a projector toward viewers within a diffusion locus, while maintaining optimum gain characteristics. More specifically, light incident on a region of the front projection screen from a predetermined projection direction is reflected by an engineered surface to a predetermined diffusion locus after undergoing substantially single reflections. The engineered surface, comprised of generating kernels, is used to optimally diffuse illumination light into a range of viewing angles, within the diffusion locus, with suitable gain profile, while optimally preserving polarization for 3D applications. Such a screen, when combined with matched polarization analyzing eyewear, provides extremely low cross-talk from any observation point. |

Device for amplifying a laser with high energy and high beam quality
The field of the invention is that of high-energy laser beam amplifiers and associated optical pumping devices. The object of the invention is to use an amplifier configuration and a cooling means which do not have the drawbacks of cryogenic systems that have been used up until now and which however make it possible both to obtain an amplified laser beam of high quality and to minimize transverse lasing effects. A laser beam amplifying device according to the invention combines four main principles, which are use of a crystal exhibiting circular symmetry so as to distribute the mechanical stresses radially; cooling of the entire external surface by a cooling liquid, so as to avoid the use of cryogenic techniques; use of a matching liquid so as to avoid transverse lasing effects; and use of pump laser beams with uniform energy distribution. |
