摘要:
A starter motor for an internal combustion engine has an electric motor, a shaft driven by the motor, and a pinion assembly arranged to engage a flywheel of the engine. The pinion assembly has a drive collar mounted to a helical spline of the shaft, an output gear and an elastic member disposed between the drive collar and the output gear. A connection shell prevents axial separation between the drive collar and the output gear. The elastic member prevents direct contact between the connection shell and at least one and possibly both of the drive collar and the output gear.

A method is provided for evaluating the tension or laxity of the soft tissue surrounding a patient's knee joint. Based on this evaluation, a surgeon may determine a desired resection depth for a knee arthroplasty procedure that will achieve an appropriate spacing between adjacent, articulating components of the knee joint.

An image of a scanned book is segmented using a feature image to map pixels corresponding to a page area and to create page objects and detect borders of the page. A book spine region is detected by locating a plain background area between two of the page objects, analyzing the page borders to detect their shape, and analyzing their shape to detect the book spine end points. Using the page borders, the feature image is examined to detect top-to-bottom and bottom-to-top declines in pixel values to determine the corners of a shadow distortion in the original scanned image. Squeeze and curvature distortion are also detected. A Bezier curve is used to model each of the three distortions detected on the page. The detected distortion is corrected by first defining a trapezoidal correction area. The intensity, squeeze, and curvature corrections are then applied along lines within the trapezoidal correction area.

A computerized annotation method achieves real-time operation and better optimization properties while preserving the architectural advantages of the generative modeling approach. A novel clustering algorithm for objects is represented by discrete distributions, or bags of weighted vectors, thereby minimizing the total within cluster distance, a criterion used by the k-means algorithm. A new mixture modeling method, the hypothetical local mapping (HLM) method, is used to efficiently build a probability measure on the space of discrete distributions. Thus, in accord with the invention every image is characterized by a statistical distribution. The profiling model specifies a probability law for distributions directly.

In a system and method for the generation of attack-resistant, user-friendly, image-based CAPTCHAs (Completely Automated Public test to Tell Computers and Humans Apart), controlled distortions are applied to randomly chosen images and presented to a user for annotation from a given list of words. An image is presented that contains multiple connected but independent images with the borders between them distorted or otherwise visually obfuscated in a way that a computer cannot distinguish the borders and a user selects near the center of one of the images. The distortions are performed in a way that satisfies the incongruous requirements of low perceptual degradation and high resistance to attack by content-based image retrieval systems. Word choices are carefully generated to avoid ambiguity as well as to avoid attacks based on the choices themselves.
摘要:
A process for forming isolation and active regions, wherein the patterning of an oxidation-barrier active stack is performed separately in the PMOS and NMOS regions. After the active stack is in place, two masking steps are used: one exposes the isolation areas on the NMOS side, for stack etch, channel-stop implant, and silicon recess etch (optional); the other masking step is exactly complementary, and performs the analogous operations on the PMOS side. After these two steps are performed (in either order), an additional nitride layer can optionally be deposited and etched to cover the sidewall of the active stack. Field oxide is then formed, and processing then proceeds in conventional fashion.

The present invention relates to a method for correlating single nucleotide polymorphisms in the preprotachykinin (NKNA) gene with the efficacy and compatibility of a pharmaceutically active compound administered to a human being. The invention further relates to a method for determining the efficacy and compatibility of a pharmaceutically active compound administered to a human being which method comprises determining at least one single nucleotide polymorphism in the NKNA gene. Said methods are based on determining specific single nucleotide polymorphisms in the NKNA gene and determining the efficacy and compatibility of a pharmaceutically active compound in the human by reference to polymorphism in NKNA. The invention further relates to isolated nucleic acids comprising within their sequence the polymorphisms as defined herein, to nucleic acid primers and oligonucleotide probes capable of hybridizing to such nucleic acids and to a diagnostic kit comprising one or more of such primers and probes for detecting a polymorphism in the NKNA gene, to a pharmaceutical pack comprising NK-1 receptor antagonists and instructions for administration of the drug to human beings tested for the polymorphisms as well as to a computer readable medium with the stored sequence information for the polymorphisms in the NKNA gene.

The invention is directed to a method of preparing porous metals, as well as to these porous metals per se. More in particular the invention is directed to the use of these porous metals in the preparation of medical items, such as implants. The invention further relates to a method of providing a porous metal coating on a substrate, in particular on the surface of a medical item, such as an implant or scaffold for tissue engineering. According to the method of the invention, a polymeric foam is impregnated with a slurry of metal particles, such as titanium, tantalum, titanium alloy or tantalum alloy particles. The impregnated foam is subsequently dried and subjected to pyrolysis and subsequent sintering. Due to the presence of metal hydrides, the formation of undesired compounds, such as metal oxides or nitrides, is avoided.

The present invention is related to the fields of genetic mapping and genetic identity detection, including forensic identification and paternity testing. This invention is more specifically directed to the use of mass spectrometry to detect length variation in DNA nucleotide sequence repeats (including variants of common alleles), such as microsatellites and short tandem repeats, and to DNA sequences provided as primers for the analysis of DNA tandem nucleotide repeat polymorphisms at specific loci on specific chromosomes.
