IPC: H04M3/22
Filed: 2004-09-25
Abstract: A system for identifying service affecting conditions on a subscriber line in the access portion of a broadband network, particularly an ADSL network. A  measurement unit provides information on the line that aids in identifying projected performance. Information from a modem on the subscriber line indicative of actual performance is obtained and compared to the predicted values. Deviations are used to identify service affecting conditions and, depending on the nature of the deviations, the type of condition affecting service on the line. The physical measurements are used to identify the length of the subscriber line. Modem information is obtained through the MIB and allows determination of the bit loading on the line. Interference sources are identified by comparing the actual bit loading to bit loading expected for a line corresponding to the measured length.

Title: A steam trap or a valve inspection and evaluation system
Inventor: NGUYEN JOHN H
IPC: G06F3/0484
Filed: 1998-07-14
Abstract: An equipment inspecting and evaluating system can be used to inspect and evaluate steam traps by detecting a level of vibrations of each trap and the surface temperature of the housing of that trap. The detected vibration level and temperature are used to determine whether or not steam is leaking through that trap and to what extent steam leakage is. An equipment management system is connected to the inspection and evaluation system by a data transmission cable and receives inspection data of the traps from the inspection and evaluation system. The management system analyzes the received inspection data for computing the number of defective traps, the ratio of defective traps to the entire traps, the loss caused by steam leakage, etc.

Filed: 2006-08-16
Abstract: To provide a mounting screw retainer structure which can prevent a mounting screw from falling down from a component and can also prevent the interference of the mounting screw with any other related component. In a fastening portion for fastening an upper retaining portion and a lower retaining portion by means of a mounting screw, the upper retaining portion has a screw hole and a cylindrical guide formed around and above the screw hole. Further, a projection is formed on the inner wall of the cylindrical guide at an upper portion thereof. In a loosened condition of the mounting screw where it is disengaged from a screw hole, the head portion of the mounting screw is caught to be retained by the projection. The upper portion of the cylindrical guide is tapered so that it has an inner diameter smaller than the diameter of the head portion of the mounting screw. Accordingly, even when the upper retaining portion is turned upside down in the loosened condition of the mounting screw, the mounting screw does not fall down from the upper retaining portion. Further, the amount of projection of a lower end portion is small, so that the upper retaining portion can be moved without the interference of the lower end portion with any other related component. This retainer structure is suitable for fastening of a cover for an air cleaner box whose installation space is narrow.
