Abstract: An integrated scheduling approach that provides VCR control functions to clients without always requiring a separate video stream for all clients. When a client invokes a resume, following a pause, the system uses a hierarchy of methods to handle the request. If an ongoing video stream is available such that the point at which the client is paused will be reached by that stream within a tolerable delay, the client is assigned to the ongoing stream.  If no such stream is available, and the client request can not be served from a buffer, the system assigns the client to a reserve stream taken from a pool of reserved server capacity. If no reserved server capacity is available, the client is given priority for assignment to the next stream to become available.

Granted: 2000-01-11
Abstract: An improved fold and wrap package providing containment of a catamenial pad prior to its use and for conveniently disposing of a soiled catamenial pad. The fold and wrap package comprises a wrapper comprising a single strip of material having a flap panel, a central panel, and an end panel; and preferably a tape tab for securing the wrapper in a disposal configuration to provide convenient disposal of a soiled catamenial pad wrapped in the wrapper. The fold and wrap package is initially configured to have a pouch and a flap. The pouch is formed by folding the cad panel back upon the central panel and frangibly bonding the end panel to the central panel at the longitudinal edges so that the end panel may be easily peeled away from the central panel to provide convenient disposal of a soiled catamenial pad.     The pouch is designed so that an unused catamenial pad may be disposed within the pouch with the flap being positioned over the mouth of the pouch and frangibly bonded to the pouch to securely close the pouch prior to use. The fold and wrap package is used by peeling the tape tab from the pouch, peeling the flap away from the pouch by breaking the frangible bonds between the flap and the pouch, removing the unused catamenial pad from the pouch, peeling the end panel from the central panel to open the pouch such that the fold and wrap package is a flat wrapper (these previous two steps may also be done in reverse order), securing a soiled catamenial pad to the wrapper, disposing the wrapper and the soiled catamenial pad into a disposal configuration, and securing the wrapper and the soiled catamenial pad in its disposal configuration by securing the tape tab to another portion of the wrapper.

Title: Automatic provisioning of trunking and routing parameters in a telecommunications network
Inventor: ASH GERALD RICHARD
IPC: H04M3/00
Filed: 1996-01-22
Granted: 2000-01-11
Abstract: A telecommunication network may be arranged in accord with the invention so that a change in provisioning data occurring at one element of the network is automatically supplied to the other elements of the network, thereby eliminating the need of having a network administration facility to communicate manually the change to the other network elements. For example, if a local central office switch is rehomed from a first toll switch to a second toll switch, then the first and second toll switches form messages respectively characterizing the rehome and then send the messages to each of the other network toll switches so that the other toll switches may update their respective routing and trunking data relating to the rehomed switch. The network is also arranged to implement a rule-based, end-to-end routing scheme which automatically selects a routing path from multiple candidates based on (a) class-of-service parameters and (b) availability of network capacity. The automatic selection of a routing path thus replaces the provisioning of routing data in the toll switches, which data was priorly needed to select the appropriate routing path.

Abstract: An improved Broadside SOG microphone assembly is realized by employing a microphone assembly having at least three ports arranged in a non-colinear fashion with the at least three ports defining and being in a "gradient" plane and with both outer adjacent differential pair of ports aligned in a direction substantially toward a prospective talker's lips. Thus, the inner port(s) is always closer to the prospective talker's lips. Each outer differential pair of ports forms a dipole which yields a high spatial gradient and, hence, higher speech sensitivity since they are pointed substantially toward the prospective talker's lips. Just as important, as the prospective talker's lip position relative to the microphone varies, this alignment of each outer differential pair of ports will result in the least change in the dipole sensitivity and, therefore, the lowest Broadside SOG microphone position sensitivity. Another advantage of this arrangement is that it similarly has significantly reduced position sensitivity with angular departure from the nominal Broadside prospective talker's lip position, owing again to the orientation of the prospective talker's lips. In a preferred embodiment, a single FOG microphone element is employed which accepts four distinct acoustic signals from acoustic transmission lines from four distinct ports arranged in a non-colinear fashion. The four ports define and are in a "gradient'? plane with both outer adjacent differential pair of ports aligned in a direction substantially toward the prospective talker's lips. Thus, the inner ports are always closer to the prospective talker's lips. Each outer differential pair of ports forms a dipole which yields a high spatial gradient and, hence, higher speech sensitivity since they are pointed in a direction substantially toward the prospective talker's lips. To this end, the outer ports are plus (+) ports and the inner ports are minus (-) ports, or vice versa,. referring to each side of the FOG element's diaphragm.

Title: Discriminative utterance verification for connected digits recognition
Inventor: CHOU WU
IPC: G10L15/06
Filed: 1996-07-15
Granted: 2001-01-02
Abstract: In a speech recognition system, a recognition processor receives an unknown utterance signal as input.          The recognition processor in response to the unknown utterance signal input accesses a recognition database and scores the utterance signal against recognition models in the recognition database to classify the unknown utterance and to generate a hypothesis speech signal. A verification processor receives the hypothesis speech signal as input to be verified. The verification processor accesses a verification database to test the hypothesis speech signal against verification models reflecting a preselected type of training stored in the verification database. Based on the verification test, the verification processor generates a confidence measure signal. The confidence measure signal can be compared against a verification threshold to determine the accuracy of the recognition decision made by the recognition processor.

Title: Enhanced, deferred messaging service
Inventor: LIEUWEN DANIEL FRANCIS
IPC: H04M3/42
Filed: 1997-03-24
Granted: 2000-02-15
Abstract: An enhanced, deferred messaging service ensures a message is received even when an answering machine is connected to a line and receives the call. In such a case, the service notes the number of rings n necessary to activate the recipient's answering machine. The service then resumes redialing and lets the phone ring n -1 times for each attempted call until either the phone is answered or a time-out occurs. If the recipient's answering machine, however, is in toll-savermode, then the answering machine may answer a second time in less than n -1 rings. If the toll-saver feature is activated, then the service notes the number of rings m which caused the answering machine to be reached in toll-saver mode. The service then resumes redialing and lets the phone ring m -1 times for each attempted call until either the phone is picked up or a time-out occurs. Thus, even after leaving a message on an answering machine, the service will attempt to reach a human.

Abstract: The vegetation control material applicator comprises a toroidal reservoir for containing a nominal amount of vegetation control material in fluid form and a circular valve assembly mounted between the reservoir and the circular saw blade of a brush saw. The reservoir and the valve assembly are mountable on the arbour of the brush saw with the valve assembly being in contact with the underside surface of the saw blade. The reservoir and valve assembly each have a diameter which is substantially less than the diameter of the saw blade. The reservoir has an opened side which is in communication with the valve assembly. The valve assembly comprises a valve disc and a valve seat. The valve disc is made of a material having the ability to resonate and to sustain a vibration therein. The valve seat is made of a material having vibration dampening properties. Therefore when an impulse is imparted by the saw blade to the valve assembly, a distortion of the valve disc relative to the valve seat causes the valve assembly to release a slight amount of vegetation control material on the underside surface of the saw blade. In another aspect of the present invention, the valve assembly comprises a set of spacers between the valve disc and the valve seat. The spacers are made of absorbent material and have a total thickness related to the viscosity index of the vegetation control material within the reservoir of the applicator.
