Abstract: A helical grooved pin for insertion into a hole in a hard host material includes a formed portion of helical lands and grooves. Pin material from the grooves is displaced to define lands at an expanded diameter relative to the pin stock material. The forming process employs a rolling die configured to produce substantially uniform cylindrical land surfaces. The helical lands have a width that is at least five times the height of the land. The expanded diameter of the formed portion of the pin is no more than 5% larger than the diameter of the pin stock material. These proportions provide a uniform, durable and reliable retaining surface to the pin which is particularly useful in applications where the host material is harder than the pin.

Abstract: L'approche proposée permet de prendre en charge l'acquisition de signaux et la synchronisation de trame dans un système de diffusion numérique qui fait appel à des codes de contrôle de parité à faible densité (LDPC). La modulation hiérarchisée assure une rétrocompatibilité, tandis que le signal de couche inférieure est codé par codage LDPC. Un signal est reçu, par lequel le signal est modulé, selon le schéma de modulation hiérarchisé qui comprend une couche supérieure et une couche inférieure. Ce signal comprend une configuration de données et une trame codée. La dépendance du signal reçu au regard de la modulation de la couche supérieure est éliminée. Le signal à modulation supprimée est corrélé avec les multiples configurations de données prédéterminées pour déterminer la configuration de données du signal. Le rapport de codage de la trame codée est dérivé en fonction de la configuration déterminée de données. Le montage susmentionné est particulièrement approprié pour un système numérique de diffusion par satellite.

Abstract: In response to a sign request including a digital document from a document-creating device 10, a digital-signed-document exchange supporting server 30 canonicalizes the digital document , calculates a digest value thereof and returns the digest value to the document creating device. When the document-creating device transmits a digital sign created by encrypting the digest value to the digital-signed-digital document exchange-supporting server 30, the digital-signed-digital document exchange-supporting server 30 creates a digital-signed document from the digital sign and the digital document and returns the document to the document-creating device. On the other hand, in response to a validation request including a digital-signed-digital document and a public key from a sign validating device 20, the digital-signed-digital document exchange supporting server 30 compares a value resulting from the decryption of the digital sign with the public key and a digest value of the digital document canonicalized and returns the result to the sign validating device.

In certain embodiments, the invention allows fluidic streams (which can be continuous or discontinuous, i.e., droplets) to be formed and/or combined, at a variety of scales, including microfluidic scales. In one set of embodiments, a fluidic stream may be produced from a channel, where a cross-sectional dimension of the fluidic stream is smaller than that of the channel, for example, through the use of structural elements, other fluids, and/or applied external fields, etc. In some cases, a Taylor cone may be produced. In another set of embodiments, a fluidic stream may be manipulated in some fashion, for example, to create tubes (which may be hollow or solid), droplets, nested tubes or droplets, arrays of tubes or droplets, meshes of tubes, etc. In some cases, droplets produced using certain embodiments of the invention may be charged or substantially charged, which may allow their further manipulation, for instance, using applied external fields. Non-limiting examples of such manipulations include producing charged droplets, coalescing droplets (especially at the microscale), synchronizing droplet formation, aligning molecules within the droplet, etc. In some cases, the droplets and/or the fluidic streams may include colloids, cells, therapeutic agents, and the like.
