Title: Method and apparatus for measuring surface cleanliness
Inventor: SCHRODER MARK STEWART
IPC: G01N21/94
Filed: 2001-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a special method which uses one set of specialized tools for quantifying the contamination of fine particles on the surface of a structural element. SOLUTION: The cleanliness of the target surface is quantified by wiping a prescribed area of the surface with a flexible, bright white cloth swatch preferably mounted on a special tool.

Title: Data relaying device
Inventor: OGASAWARA SHOGO
IPC: H04L9/32
Filed: 2001-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a data relaying device that relieves a load on a system in relaying data subjected to security via a network. SOLUTION: The system where clients, servers, printers and contents providers are interconnected is built up in a network. The client designates contents to be printed and transmits a print request to the server. The server mediates the contents to the designated printer to allow the printer to make printing. In this case, the server is configured to individually control the security depending on the client in communication among devices. As a result, since it is not required to conduct security in a unified way, overhead of data resulting from the security can be relieved so as to enhance the communication response.
