  • Patent number: 6632553
    Abstract: A water management system for a fuel cell having an anode chamber including a fuel, a cathode chamber in fluid communication with an oxidizing agent, and a proton conducting membrane electrolyte separating the chambers. The system includes a gas plenum, a first valve for controlling a first flow of a gas from the anode chamber into the gas plenum, and a second valve for controlling a second flow of the gas collected by the gas plenum into the cathode chamber. The first valve is opened allowing the first flow while the second valve is closed between the gas plenum and the cathode chamber so that effluent gas is collected in the gas plenum. When the amount of the effluent gas in the gas plenum reaches a predetermined value, the first valve is closed and the second valve is opened to allow the second flow.

  • Publication number: 20030183074
    Abstract: A piston position drift control for a free-piston device. The control includes a passage connecting internal volumes of the device, the passage being substantially shorter than an acoustic wavelength of the device; and a check valve in the passage for controlling fluid communication between the internal volumes, the check valve having an opening pressure not less than approximately 20% of a maximum pressure differential of the device at a maximum stroke. The control is passive, requires no active control once in service, provides low susceptibility to damage or fouling, and is amenable to adjustment or repair if needed. In addition, the control is small and inexpensive, and functions across the entire operational range of a free-piston device it supports. A related free-piston device including the piston position drift control is also provided.

  • Publication number: 20030158622
    Abstract: Multi-Axes Tool Compensation expands the tool compensation methods available to the CNC machine operator from the 2D world to 3D and 5 axis directly inside the CNC Controller without involving the CNC programmer to re-define tool locations and offsets defined in the G code program. The CNC machine operator can insert and override any of the cutting methods or scenarios originally pre-defined in the G code program to add 3D and 5-axis tool offsets and tool shape characteristics. These algorithms also provide for automatic tool gouge avoidance protection. Tools are also re-located to safe positions when necessary. Multi-Axes Tool Compensation technology provides for 3D and 5-axis tool definitions and tools offsets accessible to the CNC machine operator.

  • Patent number: 6604363
    Abstract: A method for matching an acoustic load and an acoustic driver in a resonant acoustic system, and the acoustic system so formed. The load and driver may be independently designed. The invention provides, inter alia, a matching volume positioned between the acoustic driver and load that is substantially greater than a stroke volume of the driver. The matching volume is sized such that, in combination with the moving mass, the characteristic stiffness of the acoustic driver and the characteristic load impedance, a resulting pressure wave produces an operating resonant frequency substantially equal to the preferred operating frequency of the load. Alternatively, or in addition thereto, a stroke volume of the acoustic driver can be adjusted.

  • Publication number: 20030136398
    Abstract: A combustion system for a hybrid solar receiver comprises a pre-mixer which combines air and fuel to form an air-fuel mixture. The mixture is introduced tangentially into a cooling jacket. A burner plenum is fluidically connected to the cooling jacket such that the burner plenum and the cooling jacket are arranged in thermal contact with one another. The air-fuel mixture flows through the cooling jacket cooling the burner plenum to reduce pre-ignition of the air-fuel mixture in the burner plenum. A combustion chamber is operatively associated with and open to the burner plenum to receive the air-fuel mixture from the burner plenum. An igniter is operatively positioned in the combustion chamber to combust the air-fuel mixture, releasing heat. A recuperator is operatively associated with the burner plenum and the combustion chamber and pre-heats the air-fuel mixture in the burner plenum with heat from the combustion chamber.

  • Publication number: 20030127196
    Abstract: An actuator device is provided for use in a view-through window covering having a plurality of cells. The actuator device includes at least one cooperating pair of control members including a first control member that engages an upper portion of each cell and a second control member that engages a lower portion of each cell. The cooperating pair of control members are engaged with the cells along a plane parallel to the plane of the window covering, whereby relative movement of the control members modifies the size of the space between the cells. The actuator device may also include an actuator mechanism selectively operable to create opposite movement of the first and second control members. A guide member may also be provided to transition the first and second control members from being aligned substantially perpendicular to the window covering plane to being aligned substantially parallel with the window covering plane.

  • Publication number: 20030125828
    Abstract: SmartPath provides CNC machinists using CNC Controllers a database of cutting methods, which will be automatically applied when the CNC Controller anticipates the upcoming scenario. SmartPath acts as a database collecting information about the machine's stresses and the machine's ability to cut a part. The CNC Controller in real time gathers this information as the machine moves and then automatically adds the information to the database. SmartPath is a form of artificial intelligent learning gathering its knowledge from the feedback of the CNC machine controller as it cuts. The operator can insert and override any of the cutting methods or scenarios.

  • Patent number: 6578364
    Abstract: A mechanical resonator for a thermoacoustic device having a compressible fluid contained within a housing, the housing having a pair of heat exchangers and a thermodynamic medium therebetween. The resonator includes a member for mimicking dynamic conditions at a position of the housing; and a linear suspension element suspending the member in the housing. The mechanical resonator saves length and eliminates high-velocity flow losses. A transducer may also be mounted with the mechanical resonator to derive power in another form from the system, for example, electricity, or introduce power into the system. In combination, the transducer and mechanical resonator allow for cool-side driving of a thermoacoustic system.

  • Patent number: 6575222
    Abstract: A method of making a fabric Venetian blind comprises helical winding of a narrow, elongated strip, which, when properly overlapped and bonded along longitudinal glue lines, will form the vanes and front and rear facings of the blind. The strips may be formed of a single, uniform material, or of adjacent, longitudinally extending portions of relatively opaque and relatively translucent fabric. An alternative embodiment uses the same winding technique to similarly form a structure of only translucent fabric, but with pockets for subsequent insertion of opaque vanes. Several alternative strip configurations and assembly arrangements are disclosed. The disclosed method and structure may also be used to form products for other applications.

  • Patent number: 6564552
    Abstract: A free-piston device has a stabilized piston drift. A piston having a frequency of reciprocation over a stroke length and with first and second sides facing first and second variable volumes, respectively, for containing a working fluid defining an acoustic wavelength at the frequency of reciprocation. A bypass tube waveguide connects the first and second variable volumes at all times during reciprocation of the piston. The waveguide has a relatively low impedance for steady flow and a relatively high impedance for oscillating flow at the frequency of reciprocation of the piston, so that steady flow returns fluid leakage from about the piston between the first and second volumes while oscillating flow is not diverted through the waveguide. Thus, net leakage about the piston is returned during each stroke of the piston while oscillating leakage is not allowed and pressure buildup on either the first or second side of the piston is avoided to provide a stable piston location.
