Abstract: Systems and methods provides for dialog management in real-time rather than turn taking. An example method included generating first candidate responses to triggering event. The triggering event may be receipt of a live stream chunk for the dialog or receipt of a backend response to a previous backend request for a dialog shema. The method also includes updating a list of candidate responses that are accepted or pending with at least on of the first candidate responses, and determining, for the triggering event, whether the list of candidate responses includes a candidate response that has a confidence score that meets a triggering threshold. The method also includes waiting for a next triggering event without providing a candidate response when the list does not include a candidate response that has a confidence score that meets the triggering threshold.

Abstract: An earcup to headband joint for headphones, wherein the headphones comprise an electrical cable that extends from the headband into the earcup. The earcup to headband joint includes joint structure that couples the earcup to the headband and that is constructed and arranged to provide for earcup translation along a vertical axis and rotation about the vertical axis, and at least one friction element in the earcup and in contact with at least one of the joint structure and the cable. The friction element is constructed and arranged to provide forces that resist rotational motion of the earcup about the vertical axis.

Abstract: The lamphouse is useful for the production of prints on variable contrast material or on conventional photographic material. A first tungsten filament lamp is provided from which light passes through a first color selective waveband filter. Another tungsten filament lamp is provided from which light passes through a second color selective waveband filter.In the lamphouse there is a removable rectangular light box. The top of the box is covered with a light diffusing and reflecting material. The bottom of the box comprises a rectangular light diffusing screen. The light box has on each of the sides adjacent to the two lamps a light entry port. In the lamphouse there are also two guide members which are parallel to the plane of the screen in the light box and on or in which the two lamps and their filters, guide mounting means and optionally lamphouse abutment means are slideably mounted.

Abstract: Impurities such as hydrogen sulfide and carbon dioxide are removed from fluids such as natural gas, synthesis gas or liquid or gaseous hydrocarbons by contact with an aqueous alkanolamine solution which absorbs said impurities from the fluid. The resultant spent impurity-enriched absorbent amine stream containing the absorbed impurities is split into two streams; one stream being routed directly to the top of an amine regenerator column and the second stream being routed to a heat exchanger where it is heated en route to an intermediate point of the regenerator column by heat exchange with the hot regenerated solution coming from the bottom of the regenerator column. The spent amine stream which is passed without prior heating directly to the top of the regenerator column is heated by condensing steam in the column which would normally escape therefrom, thereby reducing the amount of "saturation" steam which is lost from the system.

Abstract: Acidic gases, such as H.sub.2 S, COS, CO.sub.2, and HCN are removed from a mixture of light hydrocarbons by first separating the mixture into a gas portion and a liquid portion. The gas portion is compressed, water washed and scrubbed with an absorbing solution prior to separating at least one hydrocarbon from other hydrocarbons in the mixture. The liquid portion is stripped of H.sub.2 S. The stripped vapors containing the stripped H.sub.2 S may be recycled to the gas compression step.
