International Classification:

G06F 1700

US Classification:

707102, 705 8

Abstract:

An integrated system for managing changes in regulatory and non-regulatory requirements for business activities at an industrial or commercial facility. Application of this system to environmental, health and safety activities, and to food, drug, cosmetic, and medical treatment and device activities, are discussed as examples. The system: provides one or more databases that contain information on operations and requirements concerning an activity or area of business; receives information on regulatory and non-regulatory changes that affect operations of the business; converts these changes into changes in data entry forms, data processing and analysis procedures, and presentation (by printing, electronic display and/or distribution) of data processing and analysis results to selected recipients, without requiring the services of one or more programmers to re-key and/or reformat the items affected by the change; and implements receipt of change information and dissemination of data processing and analysis results using the facilities of the Internet.

International Classification:

G01N 2304

US Classification:

378 62

Abstract:

A method and apparatus for forming and reading a radiation image of an object is provided. The method is performed by placing an object of which a radiation image is to be taken adjacent a platform that is positioned between a storage layer radiation screen and an electromagnetic wave radiation source such that radiation from the electromagnetic wave radiation source which traverses the object is absorbed by the storage layer radiation screen; forming a latent radiation image of the object on the storage layer radiation screen by causing the electromagnetic wave radiation source to emit radiation, a portion of the emitted radiation traversing the object and being absorbed by the storage layer radiation screen; and reading the latent radiation image of the object from the storage layer radiation screen.

09/594304

Inventors:

Christopher E. Mitchell - Redmond WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

H04L009/00

US Classification:

380280, 380278, 713152, 713163, 713178, 713185, 713201, 370389

Abstract:

A version number is associated with an encrypted key executable to allow real time updating of keys for a system which facilitates users signing on to multiple websites on different domains using an encrypted ticket. Two keys may be used at each site during updating of keys, each having an associated one digit Hex version tag. When a key is to be updated with a new key, the existing or old key is provided an expiration time. A second key is provided from the system in a secure manner with a new version number and made the current key which provides decryption of the encrypted ticket. The system tracks both keys while they are concurrent. After the existing key expires, only the second, or updated key is used to provide login services for users. The system periodically flushes old keys.

Assignee:

Alara, Inc. - Fremont CA

International Classification:

G03B 42/08

US Classification:

250585

Abstract:

Methods and device are provided for improved storage screen readout. In one embodiment, a storage screen readout device comprises a first wavelength source and a second wavelength source, means of collecting phosphorescence stimulated by the sources, and means of effecting relative motion between the sources and the screen in order to obtain image information. The first wavelength may be selected to pump signal on the screen to be more easily readout by said second wavelength source. The sources may direct energy sequentially onto the screen, simultaneously onto the screen, any combination of the two, or combinations with other sources.

International Classification:

G06F 7/04

US Classification:

726 3, 726 2, 726 4, 726 8, 726 9

Abstract:

A user, by way of a computing device, requests and receives content from a first server at the computing device. An authentication response is also received from the first server at the computing device of the user. The authentication response includes an address of the second server and an executable script. The computing device of the user executes the executable script by issuing a request to the second server for state information corresponding to the user, receiving the state information from the second server; and determining, based on the state information, whether the user is authenticated to the second server. If the user is not authenticated to the second server, the computer device of the user displays a login module that is visually associated with the first server. Such login module collects login information for authenticating the user to the second server. If the user is authenticated in the second server, the computing device of the user issues a request to the second server for vouching information for authenticating the user to the first server.

International Classification:

US Classification:

Abstract:

Methods and arrangements are provided which associate a first user with a second user in a first device, and selectively provide information about the association of the first and second user to a second device as directed by the first user, without requiring the second user to be logged in to either the first or second device. The information about the association of the first and second user is provided to the second device via a validation code or validation protocol that essentially identifies the first user and the second user, when the first user is logged in to the second device. Here, for example, the validation code may identify the second user by an identifier and a name, and possibly provide modifications to a consent parameter associated with the second user. In certain implementations, at least a portion of the validation code may be encrypted when sent from the first device to the second device. By way of example, in certain instances, the first user may be a parent/guardian to the second user.
