Patent CA-2513686-A1 (CA)
Inventor: GIOVANNINI ARIANNA
IPC: C08L77/10
Filed: 2004-01-30
Abstract: A transparent article includes a continuous polyester matrix having at least one incompatible filler dispersed therein. The incompatible filler provides domains in the polyester matrix, each domain having a particular dimension, thus providing a range of dimensions for the domains in the article. To create haze, the dimensions are within the range of from about 380 nm to about 720 nm. Once the range of dimensions is determined, a light absorbent composition can be found which absorbs light at a range of wavelengths that at least substantially covers the range of dimensions of the domains. In doing so, it has been found that the haze of the article can be substantially masked.  Method for producing the article and for masking the haze are also provided.

Title: Quantum dot-polymer nanocomposite photodetectors and photovoltaics
Inventor: LEVINA LARISSA
IPC: H01L51/48
Filed: 2005-09-09
Abstract: The present invention relates to photodetectors and photovoltaics and in particular lead sulphide quantum dot infrared photodectors and photovoltaic devices. The present invention includes sensitizing conjugated polymers with infrared active nanocrystal quantum dots to provide a spectrally tunable means of accessing the infrared while maintaining the advantageous properties of polymers. The present invention uses such a nanocomposite approach in which quantum size effect-tuned PbS nanocrystals sensitize the conjugated polymer poly(2-methoxy-5-(2'-ethylhexyloxy-p-phenylenevinylene)] (MEH-PPV) into the infrared. The present invention achieves, in a solution-processed device and with sensitivity far beyond 800 nm, harvesting of infrared-photogenerated carriers and the demonstration of an infrared photovoltaic effect. The present invention also exploits the wavelength tunability afforded by the nanocrystals to show photocurrent spectra tailored to three different regions of the infrared spectrum.

Abstract: Un récepteur de type système global de navigation à satellite (GNSS) poursuit la porteuse à décalage binaire alterné de Galiléo (15, 10), ou des codes composites E5a et E5b utilisant un matériel de génération locale du signal composite complexe par la combinaison de composantes réelle et imaginaire générées séparément du signal complexe. En vue de la poursuite des signaux composites à code pilote sans données qui sont sur la voie en quadrature du signal de porteuse à décalage binaire alterné Galileo, le récepteur exploite des générateurs de code de bruit pseudo-aléatoire (BPA) pour produire des codes de bruit pseudo-aléatoire E5a et E5b de reproduction et des générateurs d'ondes en créneau qui génèrent les composantes réelle et imaginaire des porteuses supérieures et inférieures, et combinent les signaux pour produire le code composite complexe de génération locale. Le récepteur extrait le code composite complexe du signal reçu par la multiplication du signal reçu, dont la fréquence a été abaissée en composantes de phase et de quadrature de base de bande, par le code composite complexe de génération locale. Le récepteur utilise ensuite les résultats, qui sont des valeurs de signal de message-guide en phase et en quadrature corrélées, pour l'estimation de l'erreur de poursuite d'angle de phase de la porteuse centrale. Le signal d'erreur est utilisé pour contrôler un oscillateur à commande numérique qui fonctionne de manière classique, pour la correction de l'angle de phase de la porteuse centrale de génération locale. Le récepteur utilise également des versions de bas niveau et de haut niveau du code pilote composite complexe de génération locale dans une boucle d'asservissement de délai, et aligne le code pilote composite de génération locale avec le code pilote composite reçu en minimisant le signal d'erreur de boucle d'asservissement de délai correspondant. Une fois que le récepteur est engagé dans la poursuite du code pilote composite, le récepteur détermine sa pseudodistance et da position globale de manière classique. Le récepteur utilise également un ensemble distinct de corrélateurs pour l'alignement des versions de génération locale des codes BPA composites en phase avec les codes de voie en phase dans le signal reçu, et ensuite, récupère les données qui y sont modulées.

Title: Post retention anchor
Inventor: KELLER WILLIAM R SR
IPC: E04H12/22
Filed: 2006-03-21
Abstract: The invention is a means for anchoring a degradation-resistant treated post or one protected with a conforming, protective cover into the ground so that it resists uplift or pull-out forces of a predetermined value without compromising the integrity of the treatment or protective cover. Anchoring is accomplished by applying indentations to the portion of the post to be embedded in the ground prior to applying the conforming, protective cover or the other material degradation-resistant treatment. The indentations on the post are configured such that the protective cover will conform to the irregularities when the protective cover is applied to the post. Indentations are applied to posts prior to application of any degradation-resistant treatments so that the integrity of the treatment is not compromised by the indentation. In the preferred embodiment, the indentations are formed on a conventional square post by milling a portion or portions of the post to create inset areas, principally at the corners, prior to applying the conforming, protective cover.
