Abstract: Keyword suggestions that are category-aware (and field-proven) may be used to help advertisers better target the serving of their ads, and may reduce unused ad spot inventory. The advertiser can enter ad information, such as a creative, a landing Webpage, other keywords, etc. for example. A keyword facility may use this entered ad information as seed information to infer one or more categories. It may then request that the advertiser confirm or deny some basic feedback information (e.g., categories, Webpage information, etc.). For example, an advertiser may be provided with candidate categories and may be asked to confirm (e.g., using checkboxes) which of the categories are relevant to their ad. Keywords may be determined using at least the categories. The determined keywords may be provided to the advertiser as suggested keywords, or may automatically populate ad serving constraint information as targeting keywords. The ad server system can run a trial on the determined keywords to qualify or disqualify them as targeting keyword.

Abstract: L'invention concerne une nouvelle classe de peptides dérivés d'embryons (facteur de préimplantation) qui sont générés de manière synthétique et testés sur des cellules immunitaires sanguines périphériques et s'avèrent bloquer l'immunité activée mais non de base, inhibant la prolifération cellulaire et créant une sollicitation au moyen d'une cytokine de type T<SB>H</SB>2, de plus, ils renforcent la réceptivité de l'endomètre en augmentant l'expression des molécules d'adhésion. L'activité biologique de PIF s'exerce par liaison spécifique à des récepteurs inductibles présents sur plusieurs lignées de leucocytes. Les peptides PIF, qui sont des modulateurs immunitaires, peuvent donc avoir des applications de diagnostic et de thérapie non toxique au niveau de l'amélioration de la fertilité, réduisant ainsi les pertes de gestation; ils peuvent également servir lorsqu'ils sont administrés pour le traitement de maladies auto-immunes et la prévention de rejets de xénotransplants. En outre, les anticorps polyclonaux contre des peptides PIF sont créés et servent à mesurer avec précision des PIF dans des fluides biologiques. Ils documentent la présence et la viabilité de la gestation et contribuent à la surveillance des gestations à risque chez les humains ainsi que chez les animaux de ferme et non de ferme, à l'amélioration de l'élevage, où, actuellement, il n'existe aucun test de gestation spécifique. De plus, les anticorps PIF peuvent avoir d'autres propriétés thérapeutiques au niveau du traitement du VIH et du paludisme.

Title: Content management for high definition television
Inventor: QUAN RONALD
IPC: H04N5/913
Filed: 2005-10-25
Granted: 2012-03-20
Abstract: A high definition television video content management and/or copy protection method and apparatus are achieved by modifying portions of one or more channels of an HDTV (high definition television) signal. These modifications are generally in the blanking intervals but can extend into the overscanned portions. In one version, the signal modification defines tags or trigger bits for a content control system. This modification may follow the HDTV tri-level sync (synchronization) pulses for example, and it may occur in at least one of the HDTV video channels. In another version, portions of the tri-level sync pulse are modified to cause a reference sensing circuit such an AGC system (in a receiving device such as a video recorder) to produce an erroneous output.  Optionally, a signal may be added or inserted following the modified tri-level sync pulses. In another version, tri-level pseudo sync pulses are added in blanking or overscanned intervals. These tri-level pseudo sync pulses may be asymmetrical and may be followed by a signal. Further, any of the above modifications or signals or sync signals may be modulated (e.g., amplitude, position, pulse~width). Also provided are defeat methods and apparatus to reduce effects or to modify results of the modification processes.

Abstract: The object, namely to create a printed circuit board for an implant with improved properties in the electrical contact via the contact points of the conductor tracks on the printed circuit board, is achieved, according to the present invention, by a device for contacting and/or electrostimulation of living tissue cells or nerves, with a printed circuit board having at least one contact point for electrical contact, wherein the printed circuit board comprises a flexible multilayer system with at least one conductor track. According to the invention, the contact points for the conductor track in the multilayer system are galvanically strengthened. For this purpose, a galvanically strengthened layer is grown onto the already preprocessed contact point, for example by a galavanic process. By applying one or more additional material layers onto the contact points of the conductor tracks, the latter are anchored with greater mechanical stability in the printed circuit board and are therefore more reliable in terms of their function.
