Title: Real time scheduling method and device in satellite communication network
Inventor: JAME L PURIETO JR
IPC: H04L12/56
Filed: 2001-05-22
Abstract: PROBLEM TO BE SOLVED: To schedule sequence in which data packets from a plurality of uplink channels are organized in the downlink channel of a satellite communication network in real time. SOLUTION: A satellite 10 includes uplink channels and a downlink channel for transmitting data packets between users 15 to 30, a ground-based station 35 and the other user terminals. Queues 104 to 110 in the satellite collect the data packets from uplinks 40 to 55 and output the data packets to a downlink 60 by using a dynamically allocated bandwidth. A scheduler 152 allocates a bandwidth to at least one queue and continuously changes the quantities of a bandwidth allocated to each queue while the queue buffers the data packets between the uplinks 40 to 55 and the downlink 60.

IPC: H03M1/12
Filed: 2001-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a multi-input analog/digital converter that hierarchically couples multiplexers in multi-stages, selectively receives many analog signals and applies analog/digital conversion to the selected signals with an inexpensive configuration. SOLUTION: Outputs of (n+1) sets of 2nd stage multiplexers BO-Bn are connected to (n+1) sets of input terminals of a 1st stage multiplexer A, and an output of the multiplexer A is given to an analog/digital converter 1. A controller 2 generates a selection signal Sa to allow the multiplexer A to select one by one each of the input signals by each period of an input clock CL and generates a selection signal Sbj (j=0-n) of the multiplexer Bj so as to select an input signal to the multiplexer Bj whose output is selected synchronously with the timing when the multiplexer A starts selecting an output of the multiplexer Bj (j=0-n) on the basis of the selection signal Sa.  Through the configuration above, since the multiplexer Bj reaches a state of selecting one input signal for the (n+1) period of the clock, a large settling time is not a problem and the multi-input analog/digital converter can employ inexpensive multiplexers.

Inventor: GOTO TAKAHARU
IPC: H01M8/06
Filed: 2001-06-29
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration in an evaporating capacity even in the case when liquid fuel remains in an evaporator in a leaning way. SOLUTION: The high-temperature gas generated by a combustor 29 is exhausted outside via a supply duct 31, an evaporator 33 and an exhaust duct 35. Liquid fuel F comprising water and alcohol is fed to the evaporator 33 from a fuel feeding hole 39a, and heated by the high-temperature gas to become steam S. Then, it is fed to a fuel refining part from a steam discharge opening 41a. To the combustor 29 that is horizontally arranged to a vehicle, the evaporator 33 is tilted in such a manner that the outlet part 33b of the high-temperature gas is located higher than the inlet part 33a. Consequently, even in the case when the vehicle is tilted in such a manner that the combustor 29 side is lifted, the residence of a large amount of liquid fuel in the outlet part 33b side with the lower heat exchange capacity compared with that of the inlet part 33a is prevented.  To the tilt in the direction orthogonal to the above-mentioned tilt, a movable vane 57 provided in the supply duct 31 is operated to allow the high-temperature gas to flow toward the side where a large amount of liquid fuel in the lower position side of the tilt remains.
