EP105604 Western european software patent - A dual mode encoding/decoding technique for use in a digital transmission system. - Gauss The first coding mode utilizes predictive differential coding to provide a precision which can be greater than that obtainable by coding information solely with the allotted number of bits, while the second mode assures at least a minimum precision for the allotted number of bits. In the first coding mode, information to be transmitted is coded into a preselected combination of first and second digital words such that the average number of bits per word in the combination is not greater than the allotted number of bits. The first coding mode appears on busses 144 and 145. gauss.ffii.org /PatentView/EP105604

Personal rapid transit - Wikipedia, the free encyclopedia The particular advantage of dual mode systems is that they use existing roads to provide a large initial network, thereby circumventing the initial downside of the network effects. Transit police are not required because riders are not forced to share a cabin, and criminals cannot easily predict where vehicles will go, and so cannot wait for commuters. In all transit systems, vehicles are depreciated on a schedule that accounts for the average number of empty seats per vehicle, and the number of trips per day. en.wikipedia.org /wiki/Personal_rapid_transit

Dual mode bus - Wikipedia, the free encyclopedia A dual mode bus is a bus that can run on power from two different sources, typically electricity from overhead lines and Seattle, Washington used similar dual-mode buses in its downtown bus tunnel until late 2004. Boston installed dual mode buses on its Silver Line in en.wikipedia.org /wiki/Dual_mode_bus

Patent 6047120: Dual mode bus bridge for interfacing a host bus and a personal computer interface bus Also, for a 64-bit mode operation, in accordance with PCI protocol, the expansion bridge initially begins in a 32-bit mode for three or four clocks until the bridge receives acknowledgment from the PCI device indicating whether the PCI device is also capable of 64-bit operation. a first path configured to connect the first bus operating in a first mode to the bus; For connection of a single 64-bit bus to bus interface unit 132, signals from the left and right halves of the 64-bit bus are merged within the bus interface unit then routed through the 64-bit processing unit to the controller interface unit for subsequent output to the bridge controller (FIG. www.freepatentsonline.com /6047120.html

Metro Hybrid Bus Program The dual-mode bus operates as a conventional diesel bus on surface streets and as an electric trolley bus in the 1.3-mile tunnel under the Seattle central business district. King County Metro Transit presently operates a fleet of 236 Breda dual-mode buses that have reached the end of their 12-year useful life. Upon reviewing the bus industry in 2000, it was determined that all of the vehicle demonstration data and performance information was based on a 40-foot urban transit bus. transit.metrokc.gov /am/vehicles/hy-dieselprog.html

United States Patent Application: 0030065861 If a split mode is not indicated, the SM board receives a coherent bus device map from the active SM at processing block 1115, enters a warm standby mode at processing block 1125, and loads all High Availability (HA) Aware compatible device drivers and places them into a pending start state at processing block 1140. If the SM board is to not operate in cluster mode at decision block 1225, the board assumes either normal RSS or single host operation mode at processing block 1235 and starts all HA Aware device drivers for the devices in both segments at processing block 1240. The bus arbiter and control module 825 is used to provide 860 bus arbitration on the two busses 740 and 750 and allow for coordinated control of the two busses 740 and 750 between system masters. appft1.uspto.gov /netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PG01&p=1&u=/netahtml/PTO/srchnum.html&r=1&f=G&l=50&s1="20030065861".PGNR.&OS=DN/20030065861&RS=DN/20030065861

Digital bus communications system - United States Patent 4,161,786 In the dual mode embodiment, time slots in a first predetermined (or static) set in the repetitive framed sequence are available for static slot assignment, e.g. In this third form, the dual mode system may be dynamically varied to accommodate any desired current usage of both bursty (low duty cycle) and longterm (high duty cycle) subscriber terminals. single mode systems, all slots may be contention slots, or all slots may be static slots. xrint.com /patents/us/4161786

Dual mode transmitter - US Patent 6531896 The serial bus transmitter of claim 1, wherein the output stage furnishes an output signal indicative of bits of a digital signal, and the output signal comprises a current signal when the output stage is in the current signaling transmission mode. During the current mode, the NI and NIB signals are logic one signals that cause the NMOSFETs 132 and 138 to operate in their linearly resistive regions, i.e., regions in which the drain-to-source voltages of the NMOSFETs 132 and 138 are approximately zero volts. Also coupled to the local bus 204 is a north bridge, or memory hub 206, that interfaces the local bus 204 to a memory bus 208 that is coupled to a system memory 210. www.patentstorm.us /patents/6531896.html

High Performance VME Whether operating in Master or Slave mode, the Dual E board is capable of quickly initiating and sustaining high data transfer rates on the VMEbus. When operating in Master mode the Dual E board can fetch instructions and data from remote VME memory via reads performed across the VMEbus. The use of low voltage (3.3v) and ultra-low voltage (2.5v) components allows the Dual E board to be clocked at much higher rates, producing the high performance needed to support two interfaces while still maintaining low power consumption, low noise and minimal heat dissipation and cooling requirements. www.jentech-ntds.com /high_perf_vme.htm

nForce2: single-channel mode vs. dual-channel mode Attention: the two-channel mode utilizes usual memory modules with the memory size being equal to the total size of the modules installed, not to the half of it (it concerns all dual-channel chipsets). The character of the results is similar, the single-channel mode with the integrated video yields rather poor results; the dual-channel mode gives a gain of just 2-3%, and the rest of the bandwidth reserve is enough to make up for operation with the integrated video core. We used the processor coupled with the 166MHz bus, and the memory working at the same frequency on both chipsets at the minimal timings ( remember that DDR400 with CL 2.5 used on the KT400 worsens performance of this chipset). www.digit-life.com /articles2/nforce2-1vs2channels/index.html

Personal rapid transit The Danish RUF system is dual mode because the vehicles can operate on guideways in an automatic mode, or leave the guideways and operate on city streets, with drivers controlling them. A particular advantage is that dual mode operation can reduce the initial expense of the guideway network. A notable disadvantage is that any dual mode system's performance is limited by its compatibility with existing infrastructure. www.brainyencyclopedia.com /encyclopedia/p/pe/personal_rapid_transit.html

Patent 6169954: Intelligent public transit system using dual-mode vehicles system may operate in dual mode in the sense that when not on the special roadway whereon electromagnetic propulsion is the only option, it may be operated as an electric vehicle capable of self-propulsion on a typical surface roadway. Some of these prior art systems involve no more than providing improved communication between transit authorities and passengers, while others attempt to provide independent modes of travel on special roadways that are modified from existing roadways, or built new at extravagant costs. The transit system of claim 1 further comprising an enclosure covering substantial portions of travel lanes of the controlled roadway, such that air within the enclosure is caused to move in the direction of transport vehicle travel, therefore reducing air friction impeding progress of vehicles moving on the roadway. www.freepatentsonline.com /6169954.html

dual-mode electric, automated transit and transportation concepts IMT (Individual Mass Transit) - a concept that is still pretty vague in terms of technology - but the concept description is good as is a preliminary analysis of functional utility. It is being developed at the Center for Rapid Transit Systems at the Virginia Polytechnic Institute in Blacksburg, VA. The National Automated Highway System Consortium (NAHSC) is currently inactive in the U.S. However, the recently formed Cooperative Vehicle-Highway Automation Systems group is working on the same issues in the U.S. - a small vehicle designed for neighborhood use that can also be suspended from a cable for longer, faster trips. faculty.washington.edu /~jbs/itrans/dualmode.htm

Seattle: The Metro Tunnel Northbound and eastbound buses (Metro Transit 41, 71, 72, 73, 255, 256, 258, 266, 301, 306, 307, and 312) stop at a platform on the south side of the station, which is designated Bay A/Bay B. Here the buses disconnect from the overhead electric catenary wires by lowering their poles. In 1993, while the regional transit ballot measure was in preparation, consultants estimated a $2 billion cost for the core segment of the light rail line. Sound Transit, which was created to develop the Sound Link light rail line in addition to regional commuter rail and bus lines, has been trouble plagued from its inception in 1996. world.nycsubway.org /us/seattle/tunnel.html

Patent 4608667: Dual mode logic circuit for a memory array The dual mode circuit receives two independent input logic signals, and drives two sets of on-chip circuitry such that in one mode input A drives outputs A and B (in phase) and in a second mode input A drives output A and input B drives output B (in phase). The dual mode circuit is most efficiently realized in terms of power consumption, total device count and the number of stages of delay using cascoding and collector dotting of current switch circuits. The mode of the circuit is established by switching M1 and M2, the lower portion of the cascoded current switch. www.freepatentsonline.com /4608667.html

Ultrasonic Flow meters from KATRONIC Ultrasonic Flowmeters for Permanent Installation Dual mode flowmeters (transit-time and Doppler - NoiseTrek™) In those rare cases where the amount of gaseous or solid content in the liquid becomes too high for the transit-time mode to operate, the unit can revert to the Doppler - NoiseTrek™ mode, which relies on particles or gas bubbles flowing with the liquid. The difference in transit times of the ultrasonic signals is an indication for the flow rate of the fluid. www.katronic.co.uk /prod_02.html

SEATTLE TRANSIT ROUTES Such routes use "dual mode" buses, capable of operating as electric trolleybuses in the tunnel and as diesel motor buses outside the tunnel. Presumably, streetcar routes were constructed which in 1940 became various branches of trolleybus route 7, later "dual mode" bus routes 71-72-73, using diesel power north of the University area. Future plans are to transfer use of the tunnel to Sound Transit, which expects to open a light rail line into Seattle in 2009, using the tunnel. members.aol.com /chirailfan/seadate.html

Dual Mode. Dual weight? Double cost? Dual Mode is a concept which, in its outward appearance, might be said to out-Jetson PRT. Dual Mode guideway would have to be over-engineered to allow for weight of the largest passenger vehicles-- in a pallet system (see below) this would include the engines, transmissions, drive shafts, suspensions, axles, cargo, etc. of conventional autos. Dual Mode has been designed to combine the grade separation and automation advantages of PRT with the irresistable attractiveness of the private automobile. kinetic.seattle.wa.us /nxtlevel/prt/ruf.html

SkyscraperCity Forums - Personal Rapid Transit Different projects of PRT and Dual Mode exist in the USA (were subsidized by the Federal Government), Canada, European Union (subsidized now by EU), South Africa, Norway, Russia, South Korea (subsidized now) and many other countries. Dual Mode combines ability to go on elevated automated guideway and on conventional roads. The advantages of Sky Taxi are: beautiful cheap guideway, high speed and throughput, safety and comfort, weatherproofness, noiselessness, low electricity consumption, variety of convenient transportation modes (including several cargo modes) and variety of vehicles, adaptability to any type of city/suburb (both Hong Kong and Los Angeles!) and to any part of population. www.skyscrapercity.com /showthread.php?t=116375&page=2

Electric Highway Vehicles Long-term tests, at frequent intervals, with Fradella's demo, indicate that normal battery service life of 10 years can be expected, in EVs operated in the modes described here. In-transit power supplied by the roadway would be limited to about 5-kw, by the onboard battery charger. "Wind farms" used for in-transit EV power would not need to restrict operation to such a narrow wind speed range, as is the case when their outputs must be synchronized to a central power grid. rpm2.8k.com /car.htm

NW Virtual Transit Center-Metro Bus Tunnel This is where bus operators switch off their diesel engines and connect the bus to the overhead power above by use of a retractable pantograph. In 1983, while other cities were considering light rail and bus transit malls to solve their transportation problems, Seattle took a dramatically different approach. Bus riders on tunnel routes experienced a much faster trip through downtown than if they were above. www.nwvirtualtransit.com /seattle/bustunnel.html

FBUS & MBUS adapters: Dual-mode adapter The mode switching is automatic because the switch shown in the general dual-mode adapter in chapter 1 is replaced with a field-effect transistor switch. The mode selection is made with the RTS line. True Nokia-compatible applications holds the RTS in -12 V for the FBUS mode. www.panuworld.net /nuukiaworld/hardware/cables/dual.htm

Bladerunner dualmode concept from the United Kingdom features large truck that can operate on an existin railroad Although its load carrying portion can be either a lorry or a bus the dualmode vehicle resembles a familiar articulated truck up to 16.5 metres long under present regulations. His dualmode project is being backed by freight trailer and body builder Don Bur, Stoke-on-Trent, and the government's Department of Trade and Industry. No time need be wasted in transferring goods or people from one mode of transport to another. faculty.washington.edu /jbs/itrans/bladerunnerupdate.htm

BiWay Dual-Mode Transport Bus and taxi services will be reorganised around the new system feeding passengers to it. The effects on airlines, railways, bus companies, taxis, car manufacturers, the oil companies and will be huge. The changeover therefore, should not be too traumatic for the industry. www.buick.co.uk /biway/impact1.html
