Patent number: 8423191Abstract: A cast iron brake caliper with improved fatigue life, and a process and process equipment for pre-stressing a cast iron brake caliper to provide improved fatigue life, is provided. In the process, a load is applied to a cast iron caliper, where the load is high enough to locally yield and plastically deform the cast iron material, but not high enough to cause material failure, such as cracking. Upon load removal, residual compressive stresses in the cast iron caliper lower the mid-point of the stress range the plastically-deformed region of the caliper sees during in-service use, and thereby lowers the peak stress seen in this region, increasing fatigue life. The process permits a cast iron brake caliper to be designed to use less material and thus fit within constrained wheel rim envelopes, without the need to resort to high cost materials or other alternative design strategies.Type: GrantFiled: August 24, 2011Date of Patent: April 16, 2013Assignee: Bendix Spicer Foundation Brake LLCInventors: Ronald S.

Hence, the system and method can allow an operator to see when alarms occur, their sequence, relations and priority, which aid the operators cope with inevitable alarm floods.Type: GrantFiled: December 19, 2008Date of Patent: September 18, 2012Assignee: Honeywell Internatonal Inc.Inventors: Peter Bullemer, Dal Vernon C.

Publication number: 20120215335Abstract: A system, a method and a computer program product for identifying incompatible manufacturing tools. The system receives measurements of products that were subject to a manufacturing process involving a plurality of manufacturing tools. The measurements pertain to a performance characteristic of each product. The system evaluates whether each manufacturing tool implemented in a sequential manufacturing process individually performs normally based on the received measurements. In response to evaluating each manufacturing tool implemented in said manufacturing process individually performs normally, the system evaluates whether a first combination of the manufacturing tools together in sequential manufacturing process perform normally based on the received measurements.Type: ApplicationFiled: February 18, 2011Publication date: August 23, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Robert J. Baseman, Fateh A. Tipu, Sholom M. Weiss

Patent number: 8239197Abstract: A system and method for efficiently transcribing verbal messages transmitted over the Internet (or other network) into text. The verbal messages are initially checked to ensure that they are in a valid format and include a return network address, and if so, are processed either as whole verbal messages or split into segments. These whole verbal messages and segments are processed by an automated speech recognition (ASR) program, which produces automatically recognized text. The automatically recognized text messages or segments are assigned to selected workbenches for manual editing and transcription, producing edited text. The segments of edited text are reassembled to produce whole edited text messages, undergo post processing to correct minor errors and output as an email, an SMS message, a file, or an input to a program. The automatically recognized text and manual edits thereof are returned as feedback to the ASR program to improve its accuracy.Type: GrantFiled: October 29, 2008Date of Patent: August 7, 2012Assignee: Intellisist, Inc.Inventors: Mike O. Webb, Bruce J. Peterson, Janet S. Kaseda

Patent number: 8234001Abstract: A method of analyzing production steps includes inputting application data associated with a production process having a plurality of process steps into a memory with each of the plurality of process steps including a plurality of tools. The method also includes loading process data associated with one of the plurality of process steps into the memory, performing a tool commonality analysis on each of the tools associated with the at least one of the plurality of process steps, identifying all tool-to-tool differences for the at least one of the plurality of process steps, performing a tool stratification analysis to identify one of the plurality of tools that provides the largest variance contribution to the at least one of the plurality of process steps, and stopping the one of the plurality of tools that provides the largest variance contribution to the at least one of the plurality of process steps.Type: GrantFiled: September 28, 2009Date of Patent: July 31, 2012Assignee: International Business Machines CorporationInventors: James Rice, Dustin K.

Patent number: 8229584Abstract: An abnormality detection system includes a measurement unit, a decision unit, an alarm unit, and storage units, and serves to detect the abnormality in a control characteristic value of a plurality of products manufactured on the same production line. The decision unit receives the control characteristic value stored in the storage unit, and decides whether an abnormality exists, based on that value. More specifically, the decision unit decides that the control characteristic value is abnormal when, with respect to m (m is a natural number) pieces of the products that are consecutively manufactured, an absolute value of a difference in control characteristic value between each of the products and another manufactured immediately before the former is equal to or less than a predetermined constant.Type: GrantFiled: January 16, 2007Date of Patent: July 24, 2012Assignees: Renesas Electronics Corporation, NEC CorporationInventors: Masanobu Higashide, Gouki Sadakuni

Patent number: 8229587Abstract: A semiconductor fabrication facility (fab) configuration module is defined to virtually model physical systems and attributes of a fab. A data acquisition module is defined to interface with the physical systems of the fab and gather operational data from the physical systems. A visualizer module is defined to collect and aggregate the operational data gathered from the physical systems. The visualizer module is further defined to process the operational data into a format suitable for visual rendering. The processed operational data is displayed within a visual context of the fab in a graphical user interface controlled by the visualizer module. An analyzer module is defined to analyze data collected by the visualizer module and to resolve queries regarding fab performance. An optimizer module is defined to control systems within the fab in response to data collected by the visualizer module, data generated by the analyzer module, or a combination thereof.Type: GrantFiled: February 20, 2009Date of Patent: July 24, 2012Assignee: Muratec Automation Co., Ltd.Inventors: Karl Shieh, Michael A.

Patent number: 8223371Abstract: In a data processing method, import request data transmitted from a client is received. By comparing the application list against information indicating license settings of the application that are stored in advance, a determination is made as to whether or not the processing specified in a workflow is executable. A temporary workflow list is created, and a determination is made as to whether or not the upper limit for the registerable workflow number and data size is exceeded. When it is determined as registerable, execution data for executing respective workflows and display data for controlling display included in the temporary workflow list are acquired from the client, and the display is controlled so as to display the executable workflow and the inexecutable workflow in a fashion such that the executable workflow and the inexecutable workflow can be identified.Type: GrantFiled: February 18, 2009Date of Patent: July 17, 2012Assignee: Canon Kabushiki KaishaInventor: Yuka Kamiya
