Abstract: A surgical laser system includes an array of laser diodes that are configured to output laser energy, a fiber bundle, a delivery fiber, and a tubular sheath. The fiber bundle includes a plurality of optical fibers and has a proximal end that is configured to receive laser energy from the array of laser diodes. The delivery fiber includes a proximal end that is configured to receive laser energy from a distal end of the fiber bundle. The tubular sheath defines a lumen, in which at least a portion of the delivery fiber is disposed. The tubular sheath is insertable into a working channel of an endoscope or a cystoscope. A distal end of the tubular sheath is configured to deliver laser energy discharged from the delivery fiber into a body of a patient.

Abstract: A multi-table-based grant generator in accordance with the present invention solves the issue of bandwidth granularity, while maintaining the simplicity of a table approach. The present invention grant generator provides grants of fine granularity for regulation of upstream transmission of cells in an ATM PON. Multiple grant tables having differing bandwidth granularities are linked together through a simple grant distribution mechanism. The grant tables and grant distribution mechanisms can be recursively linked to achieve a number of different granularities. The grant generator of the present invention is based on multiple grant tables with a combination of multiplexers, dividers, and address counters. The grant generator provides both larger and smaller bandwidths for data grants as well as PLOAM grants without large size grant tables. In one exemplary embodiment of the present invention, improved granularity is achieved, where a first grant table is used for one size of bandwidth grant, e.g.

Abstract: A solution to the music-on-hold problem associated with audio conference calls. The music on-hold-problem occurs when a conferee having music-on-hold puts the conference call on hold, resulting in a continuous stream of music being transmitted to the other conferees. Such a conferee is called an offending conferee. The solution presented herein is to prevent music-on-hold signals emanating from an offending conferee from being passed through an audio conference bridge to the other conferees. This is accomplished, in particular embodiments, by directing a merging/summing subsystem of the audio conference bridge to temporarily stop combining audio emanating from the offending conferee from being combined or merged onto audio channels through which the other conferees communicate on the audio conference.

Abstract: An arrangement for a teleconferencing bridge allows one or more users to control at least one characteristic of at least some of the input signals received by the bridge, such that the output signals received by each user in a teleconference is a user-controlled combination of all the input signals, including the changed input signals. The arrangement allows a rich set of audio bridging features to be provided cost-effectively. Those features include subconferencing, monitoring, whispering, muting, complex gain control, and pseudo stereo.

Abstract: In an illustrative embodiment, an audio/video conferencing system comprises two or more audio/video terminals, in which the transmitted and/or received audio is automatically adjusted to provide synchronization between audio and video during periods of monologue (i.e., single talker active for significant duration). During interactive periods in which more than one talker is active, the audio delay is automatically adjusted to be less than the video delay, thus improving audio conference quality.

Abstract: An arrangement for teleconferencing voice and data is provided through an arrangement that includes a voice bridge that offers individual control of the conferencing setup. The voice bridge comprises a crossbar with crosspoints that include a series connection of two switches and a resistor. One switch of each crosspoint is associated with the row of the crosspoint while the other switch of the crosspoint is associated with the column of the crosspoint. A user, connected to a selected row and column of the crossbar for the "talk" and "listen" functions, respectively, controls the row switches in the crosspoints connected to the user's row and the column switches in the crosspoints connected to the user's column.

Abstract: Processors (101) of a multiprocessor system (FIG. 1) communicate across bus (150) via a low-latency packet protocol featuring per-logical channel input queues (143) and output queues (144), different per-processor priorities for sending data packets (FIG. 10) and data packet-acknowledging "quick" messages (FIG. 11), and separate buffers (923; 918) for receiving data packets and "quick" messages, respectively. Transmitted data packets afflicted by error, receive buffer overflow, and input queue-full conditions are discarded by the receiving processor and are retransmitted by the sending processor.

Abstract: An electronic circuit board electrically connected to other circuits of a data processing system by means of a bus, may be removed and re-inserted in the system without the necessity of disabling other circuits connected to the bus. A latch actuated switch provides a control signal in anticipation of circuit board removal. The control signal activates a finite state machine which seizes control of the bus after completion of any current bus communications and stops the generation of clock pulses normally required in bus communications. When contact is physically broken between the board and its corresponding connector, the finite state machine restores the bus clock pulses and relinquishes control of the bus. When a board is to be inserted in an open connector, contact between the board and the connector is sensed by the finite state machine which causes the bus to be seized and the bus clock pulses to be temporarily inhibited.
