Title: Protective garment with card displaying or recording data unique to authorized wearer and readable through garment pocket window
Inventor: REILLY JOHN J
IPC: G09F3/20
Filed: 2004-04-01
Abstract: A protective garment, which is intended to be only worn by a wearer who is authorized to pass through a security perimeter, comprises a pocket, which defines a window, a flap, which is movable between a position wherein the flap covers the window and positions wherein the flap does not cover the window, and a card, which is disposed in the pocket. The card displays or records data, which are readable through the window by a human, by an electronic reader, or by both, and which are unique to the authorized wearer of the protective garment. The data may comprise symbolic data, such as bar code data, and may comprise a photograph of the authorized wearer of the protective garment. When the flap covers the window, the flap protects the data against becoming illegible because of foreign matter, such as soot, or because of surface abrasion.

Title: Packaging for contact lenses
Inventor: HAMILTON RONALD S
IPC: B65D/
Filed: 2002-11-07
Abstract: A package (10+20+30) for contact lenses (10), especially 'daily-disposable' lenses, in which the overall volume of the package and the internal volumes of the lens-holding cavities (20) in the package are minimised. Volume minimisation is achieved by giving the lens package at least two of the following characteristics: (a) each cavity (10) is generally circularly symmetrical; (b) the concave internal surface (24) of each cavity (20) is formed with a radius (RP) that is within 200 microns of the radius of curvature (RL) of the convex outer surface (12) of the contact lens (10) held in that cavity (20), to give a ratio (RP/RL) of these two radii that is less than 1.2, and preferably less than 1.1; (c) each cavity (20) is formed with a sagittal (axial) height (SAGP) such that when each cavity (20) is loaded with a respective single contact lens (10) having a sagittal height (SAGL), together with a quantity of preservative fluid sufficient to about half-fill the cavity (20) and then sealed by adhering a vapour-impermeable foil (30), the vertical clearance in the loaded and sealed cavity (20) is less than 2.5 millimetres and the ratio (SAGP/SAGL) of sagittal heights is less than 1.6;  (d) the internal clearance diameter (ODP) of each cavity rim flange (28) and the diameter (ODL) of each contact lens (10) have a ratio (ODP/ODL) that is less than 1.4, and preferably less than 1.2. The packages (10+20+30) are preferably multi-cavity packages, with each cavity (20) holding a single lens (10) and all the lenses (10) being inserted into their respective cavities (20) with a common orientation such that a wearer of the contact lenses (10) has the assurance that a lens (10) can always be retrieved from a cavity (20) in a standard orientation. The internal surface (24) of a cavity (20) preferably deviates from sphericity by being formed with undulations (50) to break capillary attraction between the lens (10) and the cavity wall (24) so aiding extraction of the lens (10) from the cavity (20). On the instructions of an ophthalmic practitioner, packages of suitable lenses can be made up and dispatched by courier or by post to wearer of the lenses.

Title: Method and apparatus for secure delivery and rights management of digital content
Inventor: JOHNSON WOODROW W
IPC: G06F1/00
Filed: 2004-05-21
Abstract: A secure distribution system utilizes a content viewer that consists of an applet that is downloaded to a user's conventional browser when the user logs into a publisher's server. The content viewer requests a selected document from the server by referring to the document name or URL. The server retrieves the document and forwards it to the viewer in encrypted form.     The viewer then computes a document identifier from the encrypted document and uses the identifier to request a key in order to decrypt the document. The key is forwarded from the server to the viewer that then decrypts the document and displays it in the viewer. Since the document is processed by the viewer and displayed only in a window associated with the viewer, none of the conventional browser functions has to be disabled. Further, since the document is downloaded in encrypted form, it cannot be stored or forwarded using the conventional browser.
