摘要:
The information retrieval method and apparatus includes a group of geographically widely-distributed terminals, which accept a remotely located host computer. Each terminal includes a memory for storing a plurality of items of call origination information. A call original circuit transmits individual ones of the items of call origination information via a communication path to the switching system for causing it to extend the path to the host computer. Logic circuits transfer a first one of the items of call origination information indicative of the geographically shortest communication path, to the call origination circuit in an attempt to extend a communication path, of the geographically shortest length, to the host computer. If the attempt proves unsuccessful, the logic circuit sends automatically a second one of the items of call origination information, indicative of the next shortest communication path length.

The invention is an audio mixer (100) for prioritizing audio channels. The mixer can include a plurality of audio channels (110)—in which each channel can be capable of carrying an audio signal—and can include at least one output (114). The number of outputs can be less than the number of channels and the stage (116) immediately following the output is an output stage. Each channel can include an audio shaper (122) that modifies the audio signals of the channels and can include a priority database (126). The channels can be ranked in the priority database based on their priority in relation to one another. Control logic (128) of a highest ranked channel (N) can signal the audio shapers to modify the audio signals on at least some of the lower ranked channels (1, 2) in accordance with a predetermined priority response.
摘要:
Apparatus for downloading videotex information via a host computer includes a group of local terminals installed at a variety of locations. The terminals receive and store macro programs from the host computer. The local terminal then activates the macro programs via a set of function input devices, which generate macro program activating signals.
