1266 results about "Accessibility" patented technology

Accessibility in the sense considered here refers to the design of products, devices, services, or environments so as to be usable by people with disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers).

Method and Apparatus for Increasing Accessibility and Effectiveness of Advertisements Delivered via a Network

Network-delivered advertisements, and in particular Internet advertisements, are provided increased accessibility and effectiveness through automatic collection of ads, and later presentation of those ads by users. Typically, a publisher modifies a source file (e.g. an HTML file) to include the invention's software and metadata identifiers that uniquely identify advertising content in the source file. When the file is transferred and presented to a user, the invention's software, operating in conjunction with presentation software (e.g. a web browser), locates the metadata identifiers within the presentation (e.g. a displayed web page) and uses them to identify the portions of advertising content associated with those metadata identifiers. The portions of advertising content are then collected and transmitted to a server computer that stores them in a database so that they are associated with a user-identification code retrieved from the user's computer. The invention's software also provides each of the displayed advertisements with an associatively positioned operator control. A user of the invention may then use those operator controls to navigate among and retrieve advertisements previously viewed by that user and stored in the server computer's database. Additionally, a user may enter a login and password to assign the user-identification code to additional computers operated by the user, and thereby enable collection and viewing of advisements on multiple computers. Thus, network-delivered advertisements are provided increased accessibility and effectiveness.

Methods and apparatus for dynamic topology configuration in a daisy-chained communication environment

InactiveUS6055228AImprove effective communication performanceDigital computer detailsNetworks interconnectionFiberCommunications system
A loop isolation circuit (LIC) to enable subdivision of a single daisy-chained communication loop (e.g., FC-AL) into smaller loops and to enable joining of smaller loops into a single larger loop. An LIC comprises essentially two multiplexors configured so as to permit controlled subdivision or joining of two loop portions. In a first selected state, the LIC subdivides a communication loop in which it is inserted into two loops. This configuration sacrifices accessibility among some devices previously on the larger loop for the benefit of enhanced bandwidth and reduced overhead due to node count. Bandwidth is enhanced by enabling simultaneous operation of two (or more) loop portions for establishing and communicating over logical circuit connections. However, when a failure of a redundant loop precludes access to devices, the LIC may be set to a second state to rejoin previously subdivided loops into a larger loop. This configuration restores access among all devices sharing common access to the larger loop. The LIC of the present invention therefore enables communication loop controllers to dynamically reconfigure a daisy-chained loop communication system to enhance performance in normal operation. The LIC of further enables restoration of the larger loop to restore redundant loop configurations. The LIC of the present invention is applicable in many daisy-chained loop communication environments including, but not limited to, Fiber Channel Arbitrated Loop (FC-AL).
