Abstract: The present invention relates to improvements to powered air purifying respirators (PAPR). PAPR are known generally for use in polluted environments. A typical PAPR comprises a powered impellor arranged to draw air from the atmosphere, a filter element and a mask to provide the filtered and pressurized air to the user. Embodiments of the present invention place a generator unit, comprising a filter and impellor for pressurizing the air, behind the head of the user, and include components for improving delivery of the air to the user and improving its quality.

Abstract: A distributed computational system, with local and remote processing components, is configured to provide a user interface of the local component that is stored in the local component but is controlled and updated by the remote component.

Abstract: A computing device may receive a request for a rank-specific search link corresponding to a particular search result within a list of search results. The computing device may identify one or more search parameters used by a search engine to generate the list of search results, and identify a search result rank position of the particular search result in the list of search results. The computing device may create a rank-specific search link associated with the one or more search parameters corresponding to the list of search results and the search result rank position corresponding to the particular search result. The computing device may provide the rank-specific search link in accordance with the request. Selection of the rank-specific search link may cause information, to be presented, relating to a document to the search parameters and corresponding to the search result rank position.

Abstract: A resource request is received at a computer application, wherein the resource request has a resource specification that determines multiple resources for fulfillment. The received resource specification is evaluated, a plurality of computer resources are identified for processing of the resource request in accordance with the evaluated resource specification, and an order of processing the request among the identified computer resources is identified for fulfillment of the resource request. The resource request itself can determine network locations at which the requested resource can be found. In the case of a Web browser user application that is configured to process such a conditional resource request, the request comprises a conditional uniform resource locator (C-URL) that describes one or more network locations at which a single resource may be accessed.
