Title: Application level access privilege to a storage area on a computer device
Inventor: SPRIGG STEPHEN A
IPC: G06F21/50
Filed: 2002-08-13
Abstract: An application's access to storage (Fig. 1) is limited on a per application basis. The application is granted access to a portion of the storage (135). The application may manipulate that portion (135) of the storage (119) by creating distinct file structures within that portion (135), modifying, reading and writing files contained therein. The application is denied acces s to the storage area outside the granted portion (135). Similarly, other applications stored in the storage area (119) follow a similar paradigm. In one embodiment, the storage area is a hierarchical file structure and applications are stored as children in the file structure. The applications, however, are mapped to indicate each are stored at the file structure to prevent access to other areas of the file structure. In another embodiment, the file structure supports a shared directory that multiple applications ar e mapped to, also as a root directory but to another drive.

Abstract: A bulb shield for use in an automotive headlamp assembly, and a method for making same. The bulb shield includes a cup portion and a portion which extends from the cup portion and is configured for mounting to a reflector of the automotive headlamp assembly or to another, proximate structure. When the bulb shield is mounted, the cup portion is generally horizontally aligned with a headlamp bulb in the automotive headlamp assembly, thereby eliminating a "hot spot" which would otherwise be viewable when looking into the headlamp beam. The bulb shield includes a part made of a glass and polymer blend, and at least a portion of the part includes a vacuum aluminized coating. Such a bulb shield is relatively inexpensive and easy to make, yet can withstand the high temperatures which are typically experienced in an automotive headlamp assembly. Additionally, the bulb shield may include a complex cup shape.

Abstract: The hasp prevents the door of a boxcar or a sea-going bin from accidentally opening. One end of the hasp is locked to the door jamb adjacent to the door. The other end has a U-shaped connector which is removable from the shank of the hasp so that it can be passed through an opening in a staple on the door in order to attach to connector to the door.  The connector is re-attached to the shank of the hasp by means of a key which passes through keyways in the connector and the shank. To discourage vandalism or theft, the key can only be removed from the keyways by destroying it either by means of a blow torch or by means of a special tool which is not available to the general public.

Title: Procede permettant d'induire une differenciation de cellules souches mesodermiques, de cellules es ou de cellules souches mesodermiques immortalisees dans des cellules du systeme nerveux
Inventor: HAMADA HIROFUMI
IPC: A61K35/12
Filed: 2002-10-30
Abstract: Selon l'invention, on a constaté que, lorsque l'on effectue la culture de cellules souches mésodermiques ou de cellules ES qui sont préparées à partir d'un fragment de cellule mononucléaire séparé d'un fluide myéloïde ou de sang ombilical, dans un milieu de culture fondamental liquide, il se produit une induction de la différenciation de ces cellules souches mésodermiques ou cellules ES dans des neurones souches, des neurones ou des cellules gliales. On a également constaté que l'induction de la différenciation des cellules souches mésodermiques ou des cellules ES dans les cellules du système nerveux est favorisée lorsque l'on ajoute un extrait de cerveau ischémique dans le milieu de culture fondamental liquide. Ensuite on détermine si les cellules du système nerveux ainsi obtenues sont capable de régénérer les nerfs dans des modèles d'infarctus cérébral, de démence, de lésion médullaire et de démyélination. En outre, il devient possible d'induire la différenciation des cellules souches immortalisées dans les cellules du système nerveux par l'immortalisation des cellules souches mésodermiques par surexpression ou activation d'un gène d'immortalisation de ces cellules et ensuite par culture des cellules dans des conditions adéquates. Ce procédé est hautement utile dans la thérapie de régénération des nerfs.
