Patent CA-2584415-A1 (CA)
Title: Topical treatment with ngf and dha in damaged corneas
Inventor: BAZAN NICOLAS G
IPC: A61K38/18
Filed: 2005-09-16
Abstract: The topical administration of a combination of nerve growth factor (NGF) and docosahexaenoic acid (DHA) has been discovered to synergistically increase the effects of NGF in re-innervating the cornea. This enhancement in corneal nerve re-growth will yield a faster anatomical and functional recovery after PRK or LASIK surgeries. Using rabbits, the application of NGF and DHA resulted in increased corneal nerve surface area, increased epithelial proliferation, and decreased rose bengal staining as compared with NGF, DHA, or vehicle control individually. The topical application of NGF plus DHA in accelerating the re-innervation after PRK or LASIK, will help avoid or alleviate the symptoms of dry eye or other neurotrophic keratopathies due to corneal injuries. The topical application can be by using a corneal shield or lens. This treatment will also be useful in other corneal abnormalities including those caused by chemical burn, congenital corneal neuropathy, or acquired corneal neuropathy.

Title: System and method for mobile 3d graphical messaging
Inventor: SARNA LALIT
IPC: H04Q7/22
Filed: 2005-10-21
Abstract: Mobile 3D graphical communication is provided in a communication network for wireless devices. A sender can create and customize a 3D graphical representation that will convey the sender's content, and then provide the animation for the 3D graphical representation locally on a sender device or have a remote server provide the animation. The server provides the animated 3D graphical representation to a recipient device so that the recipient device can render the animated 3D graphical for presentation of the sender's content.  Transformation (including transcoding) techniques can be used, by the user devices and/or the server, to change the message (from text to audio, from 3D  to 2D, etc., for example) to be consistent with animated 3D graphical presentation capabilities of the user devices and/or to match user preferences. Transformation can be performed prior to or during delivery of the content. The 3D graphical communication can also be used to provide content from a content provider to any user device whether wireless or hardwire, such as with a subscription service, or can be used to post animated 3D graphical content at a network location, such as a blog.

Title: Systeme de distribution de produit fluide
Inventor: BREAULT JOHN P
IPC: B67D7/60
Filed: 2005-12-27
Abstract: L'invention concerne un système permettant de distribuer une quantité régulée de produit fluide à partir d'un conteneur de distribution comprenant un actionneur de distribution entraîné pneumatiquement. Cet actionneur comprend un cylindre de distribution et un piston de distribution mobile. Le piston de distribution peut se déplacer sous pression pneumatique à l'intérieur du cylindre, le cylindre contenant un volume de fluide hydraulique sous pression pneumatique agissant contre le piston de distribution, de sorte à empêcher de manière sélective le mouvement du piston de distribution. L'invention concerne également un moyen permettant de réduire de manière sélective le volume du fluide hydraulique dans le cylindre de distribution pour permettre le mouvement régulé du piston de distribution. Le mouvement régulé du piston de distribution entraîne le déplacement régulé du produit fluide à partir du conteneur de distribution. Avantageusement, une force peut être générée et appliquée sur un poussoir, ladite force pouvant être régulée avec précision. Cette force entraîne le mouvement du poussoir qui entraîne à son tour la distribution d'une quantité précise de produit fluide à partir du conteneur de distribution.
