Abstract: In a communication system for communicating on at least one channel group, a demodulator is disclosed. The channel group has at least one forward channel and at least one return channel, where a central station transmits data over the forward channel to a plurality of terminals at a forward data rate, and transmissions by each terminal to the central station are performed on any one of the return channels at a return data rate. The demodulator comprises a burst demodulator that demodulates received, discrete signaling packets of information over the return channels. The demodulator also comprises a message demodulator that is responsively connected to the burst demodulator, such that when the message demodulator is activated, the burst demodulator becomes deactivated when the return channel operates in a messaging mode. Thus, a feature of the demodulator is that it is a dual function demodulator that functions either as a burst demodulator, or as a continuous or message demodulator.

Abstract: Fused biconical tapered couplers formed from the pulling of heated optical fibers have controllable coupling ratios by dynamically adjusting the heat intensity and pull speed during fabrication. Fiber coupler fabrication begins by arranging two optical fibers, heating the optical fibers using a heat source a predetermined distance from the optical fibers, and pulling the optical fibers at an initial pulling velocity as the heated optical fibers soften. The heat source is moved away from the optical fibers and the pulling velocity is selectively reduced in response to a substantial change in the detected coupling ratio. Changes in the coupling ratio are controlled by selectively reducing the pulling speed and the heat intensity to a point where the pulling of the optical fibers may be halted, and the heat removed, without a substantial change in the detected coupling ratio. The coupling ratio may be monitored at different wavelengths for fabrication of wideband couplers and wavelength division multiplexers.

Abstract: A method for using a computer to control the manufacture of items in a factory determines when to schedule the manufacture of a new batch of an item or the ordering of a new batch from an outside supplier by comparing an item's reaction capacity with a limit above which the reaction capacity should lie. The limits are computed, on the basis of sales forecasts and bill of materials information, to be limits adequate to meet the forecast need for commercial items produced by the factory. The reaction capacity is recomputed and compared with the limit at a plurality of control dates. In computing an item's reaction capacity, the physical inventory, the pending orders for additional supplies of the item, the unfulfilled customer demand for the item, and the demand for the item from within the factory are all taken into account.

Award credits for a participant are accumulated in a stored record associated with the participant until redeemed. Award credits can also be acquired as an instant winner based on a random or algorithmic selection of callers to receive such credits. Awards include electronic prizes such as free long distance telephone time, electronic cash and/or service credits.
