Electromechanical safety valve system for swimming pool and spa pumps
A vacuum relief safety valve includes a housing defining an inner chamber and attached to the suction-side of the swimming pool or spa pump.

The present invention provides a method that protects symbol types by characterizing symbols as one of two types—DATA or NON_DATA, generating a symbol characterization bit, placing the symbol characterization bit at both ends of the symbol, and transmitting the symbol with the symbol characterization bits at both ends. Thus, a single byte error may affect a type bit in two consecutive symbols, and will affect one or the other of the type bits in a single symbol, but cannot affect both type bits in a single symbol. |

Semiconductor integrated circuit
A semiconductor integrated circuit having a low maximum allowable operating frequency such as an analog circuit can be prevented from being destroyed during a scan test. When a scan test mode signal is “1”, output signals of a first AND circuit and a second AND circuit are fixed to a low level and an output of an OR circuit is fixed to a high level. Therefore, output signals of fourth through sixth flip-flops FF4-FF6 are not transferred to first through third analog circuits during the scan test. On the other hand, the output signals of the fourth through sixth flip-flops FF4-FF6 are transferred to the first through third analog circuits during a normal operation. |

Pattern controlled, full speed ATE compare capability for deterministic and non-deterministic IC data
Pattern controllable LFSRs or MISRs are disclosed that are able to mask indeterminate states while performing tests on DUT outputs. At appropriate times, the MISRs or the LFSRs will mask the data being input to the MISRs or the LFSRs so that indeterminate states are not received. This allows fast/complex ATE Rx memory to be replaced by slower and smaller MISR pattern memory. At the end of a test period, the LFSRs or MISRs generate signatures which are then compared to a set of possible valid signatures for non-deterministic data. A pass/fail result is produced. By masking indeterminate states, fewer valid signatures need to be stored. Masking of the MISRs or LFSRs may be based on the fact that indeterminate states and good data in a serial output data stream tend to occur in predictable patterns, or that good data may follow alignment characters. MISR or LFSR output signatures may also be employed to test individual pattern segments instead of the entire input test pattern. This expected DUT Rx data compression implementation works for one signature (deterministic) data as well. |

Copy protection of optical discs
Subversive DSV (SDSV) sequences of data symbols having a large absolute value of DSV are extremely valuable in the copy protection of optical discs as they can induce uncorrectable read errors.

A hardware accelerator is used to execute a floating-point byte-code in an information processing device. For a floating-point byte-code, a byte-code accelerator BCA feeds an instruction stream for using a FPU to a CPU.

Memory pacing
A method, system, and program for managing memory page requests in a multi-processor data processing system determines a threshold value of available memory, and dynamically adjusts an allocation time to fulfill a page request if the available memory is below a threshold value. The allocation time to fulfill the page request is based upon a percentage of available memory pages once a page stealer commences a scan for pages. An allocation wait time is inversely proportionally adjusted depending upon the percentage of available memory. The allocation wait time has a duration that increases in time as the percentage of available memory decreases and decreases in time as the percentage of available memory increases. More specifically, an average time per page to allocate a page including a scan time for the scan in computing the average time is determined. Then a tunable value is applied to the average time to determine a wait time. In a preferred embodiment, user defined values are received that would control the allocation wait time before fulfilling a page request. |

Each input vector is associated with a variable transformation matrix that acts on the vector to invariantly permute the vector elements. Joint invariance and model learning is performed on a training set of invariantly transformed vectors over a constrained space of transformation matrices using maximum likelihood analysis. The maximum likelihood analysis reduces the data volume to a linear subspace volume in which the training data can be modeled by a reduced number of variables. Principal component analysis is used to identify a set of N eigenvectors that span the linear subspace. The set of N eigenvectors is used a basis set to encode input data and to decode compressed data. |

Lossless embedding of data in digital objects
Current methods of embedding hidden data in an image inevitably distort the original image by noise. This distortion cannot generally be removed completely because of quantization, bit-replacement, or truncation at the grayscales 0 and 255. The distortion, though often small, may make the original image unacceptable for medical applications, or for military and law enforcement applications where an image must be inspected under unusual viewing conditions (e.g., after filtering or extreme zoom). The present invention provides high-capacity embedding of data that is lossless (or distortion-free) because, after embedded information is extracted from a cover image, we revert to an exact copy of the original image before the embedding took place. This new technique is a powerful tool for a variety of tasks, including lossless robust watermarking, lossless authentication with fragile watermarks, and steganalysis. The technique is applicable to raw, uncompressed formats (e.g., BMP, PCX, PGM, RAS, etc.), lossy image formats (JPEG, JPEG2000, wavelet), and palette formats (GIF, PNG). |

An efficient network formation technique for mobile ad-hoc wireless networks according to the present invention overcomes bandwidth overhead due to generation of database update or Link State Advertisement (LSA) messages in response to changes in certain parameters (e.g., node group size, etc.) with respect to both single and plural node group scenarios. The present invention controls flooding of LSA messages triggered by changes in these parameters (e.g., node group size), thereby reducing overhead traffic during network start-up. This is achieved without impact on message delivery capability and group merge operations. After network start-up is complete and the network is formed, the present invention continues to reduce LSA flooding in a mobile scenario when radios or nodes move into and out of range with one another. |

Sensor for airborne shooter localization system
A sensor assembly suitable for use in an airborne shooter localization system. The sensor assembly has a pressure sensor subassembly with a pressure transducer positioned to detect pressure variations associated with a shock wave from a passing projectile or the muzzle blast following the shock wave. To substantially increase the signal to noise ratio for measurements of the shock wave, the pressure sensor subassembly attenuates pressure fluctuations triggered by turbulent airflow over the surface of the subassembly more than it attenuates the shock wave. This preferential attenuation is provided by separating the pressure transducer from the surface of the sensor assembly by a cavity large enough that the pressure fluctuations are substantially attenuated as they propagate across the cavity. Additionally, features of a housing that holds the pressure sensor subassembly facilitate use on an aircraft. Those features include flexibility that allows the sensor assembly to conform to curved surfaces, a skin that provides resistance to environmental conditions and allows the sensor assembly to be attached with an adhesive, and a body region that provides high vibrational impedance to prevent low frequency mechanical vibrations from being coupled to the pressure transducer. |

The method includes studying and utilizing the time lag of the direct wave and wave events, as well as the interference of these waves on a spectral graph. A calibration method is included as well. |
