Abstract: A monitoring system provides a service for users to monitor their respective Web sites, or other server systems, as seen from the computing devices of other users. In a preferred embodiment, the system includes an agent component that runs on the computing devices of service users to provide functionality for accessing and monitoring the performance of a server (preferably when such devices are otherwise idle). By running the agent component on a computer, a user effectively makes that computer available to others for use as a monitoring agent. Processing resources for conducting monitoring sessions are thus contributed and shared by members of a community. The agents are remotely configurable over the Internet, and may be configured, for example, to execute a particular Web transaction while monitoring specified performance parameters (server response times, network hop delays, server availability, etc).

Abstract: A collapsible, transportable personnel isolation apparatus or device is used to isolate a patient in a controlled environment and to protect the patient against biological or chemical hazards during transport of the patient. The collapsible apparatus has a flexible containment wall which is expandable from a collapsed, stored state to an expanded state to receive the patient. At least a portion of the containment wall is clear to allow observation of the patient within an interior region of the device. An air filtration system is provided for filtering air between the airtight interior region and the ambient atmosphere. Preferably, the apparatus has various ports therein, such as glove ports, pass through ports, access ports for cardiac leads, infusion line ports, and ventilation ports. Preferably, an air filtration device provides a flow rate of 4 to 6 cfm to prevent an undesirable build-up of carbon dioxide and provides a predetermined air pressure within the interior regions.
