Electronic audio communications system with voice command features

Abstract: An advanced electronic communication system is provided for the deposit, storage and delivery of audio messages. A Voice Message System (10) interconnects multiple private branch exchanges (12) of a subscriber with a central telephone office (22). Individual subscriber users may access the Voice Message System (10) through ON NET telephones (18) or OFF NET telephones (24). The Voice Message System (10) includes an administrative subsystem (60), call processor subsystem (62) and a data storage subsystem (64). The Voice Message System (10) enables the user to deposit a message in data storage subsystem (64) for automatic delivery to other addresses connected to the system. The Voice Message System (10) also enables the user to access the system through voice commands which are received and compared to prestored speaker independent digital templates. Once an authorized user has accessed a system, the system allows the authorized user to determine if any messages have been in the data storage subsystem (64) for him. After accessing the system, the speaker utilizes voice commands to control the system, which voice commands are received and compared to prestored speaker dependent digital templates. In response to these commands, prerecorded instructional messages are deposited in the data storage subsystem (64) for instructing a user on his progress in using the system.

Effect of molecular elasticity on out-of-plane orientations in shearing flows of liquid-crystalline polymers

Abstract: The Doi equation for the time-dependent orientational Distribution function of rodlike molecules in a nematic monodomain is solved for Startup of a simple shearing flow with director orientation initially oriented at various angles with respect to the shearing plane, where the shearing plane is defined to be parallel to both the velocity and its gradient. Two numerical solution techniques are used; one is an expansion in spherical harmonic functions, which is a generalization of a technique derived earlier for a director confined to the shearing plane, and the second is a stochastic method that integrates the equations of motion for a large ensemble of molecules. We find that at low and modest shear rates, the director can be attracted either to a time-periodic tumbling orbit that lies in the shearing plane or to an orbit that lies out of the shearing plane. This latter orbit is either a steady "log-rolling" state with average orientation perpendicular to the shearing plane or a time-periodic "kayaking" state with an orbit oblique to the shearing plane. The final state of the system depends on the shear rate and the strength of the nematic potential. In some cases both the in-plane tumbling and log-rolling (or kayaking) states are attractors; the final state then depends on the initial director.

Loudness growth in 1/2-octave bands (LGOB)--a procedure for the assessment of loudness.

Abstract: In this paper, a method that has been developed for the assessment and quantification of loudness perception in normal‐hearing and hearing‐impaired persons is described. The method has been named LGOB, which stands for loudness growth in 1/2‐octave bands. The method uses 1/2‐octave bands of noise, centered at 0.25, 0.5, 1.0, 2.0, and 4.0 kHz, with subjective levels between a subject’s threshold of hearing and the ‘‘too loud’’ level. The noise bands are presented to the subject, randomized over frequency and level, and the subject is asked to respond with a loudness rating (one of: VERY SOFT, SOFT, OK, LOUD, VERY LOUD, TOO LOUD). Subject responses (normal and hearing‐impaired) are then compared to the average responses of a group of normal‐hearing subjects. This procedure allows one to estimate the subject’s loudness growth relative to normals, as a function of frequency and level. The results may be displayed either as isoloudness contours or as recruitment curves. In its present form, the measurements take less than 30 min. The signal presentation and analysis is done using a PC and a PC plug‐in board having a digital to analog converter.

Method and apparatus for sharing asymmetric information and services in simultaneously viewed documents on a communication system

Abstract: An arrangement for realizing asymmetric collaboration utilizes a “shared Web-top”, i.e., a work space, in which different in-document applications can run and be shared. Specifically, in one embodiment of the invention employed in asymmetric collaboration, documents to be collaborated on at different users' terminals are logically identical but structurally different. Indeed, one of the collaborators, for example, a customer service agent, may have access to information that should not be made available to others of the collaborators. This asymmetric collaboration is realized by assigning a unique logical name to each information entity. Then, changes in the entity captured by some detection technique, for example, the use of document polling or event handlers, are propagated along with the name of the entity to the collaborators, where they are processed only if the relevant named entity exists. If the entity exists the logical name of the entity is mapped into its physical name which, therefore, allows asymmetric collaboration. Consequently, the name-based technique allows the collaborators, e.g., customer and agent, to share changes in the logically common portions of documents, which are structurally different.
