Abstract: Radio-based control of railroad train brakes is effected in which brake systems are computer controlled. An End of Train (EOT) system is used in which microprocessor circuits of a Locomotive Control Unit (LCU) and an EOT unit are programmed to perform these and other functions. The computer system has several states. On power on, the system enters the Setup state during which the system stores about one minutes worth of both brake pipe and equalizing reservoir pressure data. This data is later used to determine the rate of change of these pressures to determine stability. Once setup is complete, the system enters the Stability state during which operating pressures are determined. When the equalizing reservoir pressure, the brake pipe pressure and the brake pipe pressure at the end of the train are stable, the EOT unit is commanded to update operating pressures stored in its microprocessor control circuit. Once the several pressures have been found to be stable, the system goes to the Release state. The system makes transitions between the Release state and the Stability state until a predetermined decrease in brake pipe pressure is detected.      At this point, the system makes a transition to the Application state. In this state, determinations are made as to whether to transmit brake commands to the EOT unit from the LCU or to return to one of the Stability or Release states. In any of these states, the system can immediately enter the Emergency state to the Setup state, if setup has not been completed, or to the Release state if setup has been completed.

Abstract: A metallic fastening member of a one piece configuration formed of a metal material includes a shaft portion (32) and a flange portion (33) extruding outwards from a first end of the shaft portion. The shaft portion (32) includes a relatively thin-walled portion (34) to be caulked at a second end opposite to the first end. A female thread (36) is formed at an inner peripheral face of the shaft portion excluding the portion to be caulked (34). An annular groove (50) is formed at an outer peripheral face of the shaft portion (32) or at the inner peripheral face of the portion to be caulked (34), so that the shaft portion (32) has a partially thin wall. Since the wall of the shaft portion (32) is thinner at the annular groove (50), the metallic fastening member is fractured at that area to be separated into upper and lower pieces in the work of detaching the metallic fastening member from an object of fixation. Therefore, the metallic fastening member can be readily removed from the object of fixation to facilitate the recovery work for recycling purposes.

Title: Frame-based audio coding with gain-control words
Inventor: FIELDER LOUIS DUNN
IPC: G11B27/10
Filed: 1998-10-13
Granted: 2007-03-27
Abstract: Several audio signal processing techniques may be used in various combinations to improve the quality of audio represented by an information stream formed by splice editing two or more other information streams. The techniques are particularly useful in applications that bundle audio information with video information. In one technique, gain-control words conveyed with the audio information stream are used to interpolate playback sound levels across a splice. In another technique, special filterbanks or forms of TDAC transforms are used to suppress aliasing artifacts on either side of a splice. In yet another technique, special filterbanks or crossfade window functions are used to optimize the attenuation of spectral splatter created at a splice. In a further technique, audio sample rates are converted according to frame lengths and rates to allow audio information to be bundled with, for example, video information. In yet a further technique, audio blocks are dynamically aligned so that proper synchronization can be maintained across a splice. An example for 48 kHz audio with NTSC video is discussed.

Title: Conversational data mining
Inventor: SORENSEN JEFFREY S
IPC: H04M3/51
Filed: 2000-06-13
Granted: 2007-05-22
Abstract: A method for collecting data associated with the voice of a voice system user includes conducting a conversation with the user, capturing and digitizing a speech waveform of the user, extracting at least one acoustic feature from the digitized speech waveform and storing attribute data corresponding to the acoustic feature, together with an identifying indicia, in the data warehouse in a form to facilitate subsequent data mining. User attributes can include gender, age, accent, native language, dialect, socioeconomic classification, educational level and emotional state. Data gathering can be repeated for a large number of users, until sufficient data is present. The attribute data to be stored can include raw acoustic features, or processed features, such as the user's emotional state, age, gender, socioeconomic group, and the like. In an alternative form of method, the user attribute can be used to real-time modify behavior of the voice system, with or without storage of data for subsequent data mining. An apparatus for collecting data associated with a voice of a user includes a dialog management unit, an audio capture module, an acoustic front end, a processing module and a data warehouse. The acoustic front end receives and digitizes a speech waveform from the user and extracts at least one acoustic feature from the digitized speech waveform. The feature is correlated with at least one user attribute. The processing module analyzes the acoustic feature to determine the user attribute, which can then be stored in the data warehouse. The dialog management unit can include, for example, a telephone interactive voice response system. The processor can be an application specific circuit, a separate general purpose computer with appropriate software, or a processor portion of the IVR. The processing module can include an emotional state classifier, a speaker clusterer and classifier, a speech recognizer, and/or an accent identifier. Alternatively, the apparatus can be configured as a real-time- modifiable voice system for interaction with a user, which can be used to practice the method for tailoring a voice system response.

Granted: 2006-08-08
Abstract: A call center or other processing system receives an incoming communication over a computer network, determines at least a portion of a network source address of the originator, and utilizes information from the source address to select a particular type of treatment for the communication. The computer network may be an Internet Protocol (IP) network and the network source address may be an IP source address. The communication may be a service request delivered from the originator to a call center over the Internet. The source address may be processed to determine, e.g., a particular individual corresponding to the originator, or a company name, company size, Internet service provider, geographic region, or other characteristic associated with the originator. This information is then used to determine how the communication will be handled, e.g., provided with service within a designated time, handled by an agent having particular skills, etc. The source address may also be used to control subsequent activation of live agent support icons presented via a web page. Advantageously, the invention allows more efficient handling of communications received over the Internet by allowing a call center to provide appropriate customer treatment for such communications.
