An oscillator circuit is disclosed that includes a first oscillation part configured to output a first oscillation output by charging and discharging a first capacitor, and a second oscillation part configured to output a second oscillation output by charging and discharging a second capacitor. The second oscillation part includes a phase difference detection part configured to detect the phase difference between the first oscillation output and the second oscillation output, and a charging curr...

An optimized two-stroke internal combustion diesel engine, suitable for locomotive applications, has been developed to meet the EPA locomotive Tier 2 emission standards. To achieve a low emission target below the EPA Tier 2 standards for NO.sub.x (5.5 g/bhp-hr) and particulates (0.2 g/bhp-hr), several innovative changes have been made to the engine. These changes include: a new piston bowl geometry; low oil consumption piston rings; optimized surface finish cylinder liner; optimized fuel injecti...

A process is provided for reforming a hydrocarbon with carbon dioxide using a selectively permeable membrane reactor including a catalyst for accelerating a chemical reaction and a selectively permeable membrane exhibiting selective permeability, wherein a carbon dioxide reforming reaction of the hydrocarbon is accelerated by the catalyst to produce reaction products, and a specific component among the reaction products is allowed to pass through the selectively permeable membrane so specific co...

A DOCSIS 2.0 compatible sniffer which can receive legacy DOCSIS 1.x TDMA bursts as well as DOCSIS 2.0 SCDMA bursts. One embodiment uses two cable modems in the sniffer, one to capture downstream data bursts and the other to capture downstream messages and to recover the downstream symbol clock and generate an upstream reference clock which is phase coherent with the recovered downstream symbol clock. The reference clock is used by a cable modem termination system to capture upstream SCDMA DOCSIS...

Apparatus and methods are provided for wirelessly broadcasting large multimedia files to vehicles. The apparatus includes a vehicle-based receiver configured to wirelessly receive at least one group of encoded data packets at a data rate based on a number of concurrently broadcasted groups of encoded data packets, a decoder coupled to the data storage device, a data storage device coupled to the receiver, and a media playback unit coupled to the data storage device. The group of data packets cor...

A hydrogen generator is formed of a strip of corrugated material that has been folded back and forth upon itself to define a monolith having multiple fluid flow regions. At least one of these regions is used for combustion, and at least one of these regions is used for steam reforming. Water is introduced into another fluid flow region, so as to receive heat from products of combustion, and to be converted into steam. The steam is directed into one or more regions used for steam reforming, so as...

A low stress-to-seal gasket material is described. Gaskets made according to the present invention comprise at least two tapes of porous PTFE and a substantially air impermeable layer at the interface of the two tape layers. The tape layers each have a non-porous region extending the tape length and separating two porous regions. The non-porous regions of at least two tape layers are not aligned in the z-axis direction.

A method and apparatus for measuring leakage of a vehicle fuel system includes providing an apparatus having a gas source, a pressure meter and a reference orifice and connecting the apparatus to the fuel system. The fuel system is pressurized with the source. A first set of pressure measurements is obtained using the pressure meter with gas escaping the fuel system through leakage of the fuel system. A second set of pressure measurements is obtained with gas escaping the fuel system through lea...

Provided is a packet communication apparatus capable of instantly transmitting information requiring urgency without lowering data transfer efficiency even during a communication. The packet communication apparatus comprises first and second packetization sections 8 and 9 for converting signals transmitted from signal processing sections 2 and 7 to packets of predetermined forms, priority packet interleaving means 10 for interleaving the packet from the second packetization section 9 in the pack...

A dispensing device dispenses drinks or similar dosable liquid foodstuffs, especially coffee, milk, soft drinks or soups. The dispensing device includes an identification device for identifying a vertical height of a container for receiving the foodstuff and for emitting a height signal, a filling device which can be arranged in such a way that the height thereof can be adjusted in relation to the container, and a control device which sets the filling device to a pre-controllable filling level i...
