Abstract:

An exemplary embodiment of the invention is a method for providing information on product delivery in a system having a user system coupled to a host system through a network and a database coupled to the host system. The method includes receiving at the host system a request from a user system for a product delivery report. Order data from the database is obtained in response to the request and a product delivery report is generated in response to the order data. The order data includes a requested delivery date for at least one order and the product delivery report contains a span value for one or more orders. The span value is determined in response to the requested delivery date. The product delivery report is provided to the user system. Further embodiments include a system and storage medium for implementing the method.

Appl. No.:

7/450484

Inventors:

James A. Wood - Spartanburg SC
John W. Drake - Greenville SC

Assignee:

American Standard Inc. - Spartanburg SC

International Classification:

G01B 714
B60T 888

US Classification:

324160

Abstract:

A magnetic speed sensor air gap fault-detection arrangement having a two-input AND gate for each of the two-axle trucks of a railway vehicle for conditioning a gap process circuit common to each axle. Each of the gap process circuits of each axle is activated to provide a logical "1" output to an associated two-input AND gate. The associated two-input AND gates each outputs a logical "1" to a respective gap counter circuit when the axle rate reaches a predetermined value. The respective gap counter circuits count the logical "1's" and activate an associated gap fault check circuit to reset the respective gap counter circuit and to display an error code and to output a logical "1" signal to the dynamic diagnostic apparatus.
