Abstract: An apparatus comprises a radio frequency magnetic field unit to generate a desired magnetic field. In one embodiment, the radio frequency magnetic field unit includes a first aperture that is substantially unobstructed and a second aperture contiguous to the first aperture. In an alternative embodiment, the radio frequency magnetic field unit includes a first side aperture, a second side aperture and one or more end apertures. In one embodiment of a method, a current element is removed from a radio frequency magnetic field unit to form a magnetic field unit having an aperture. In an alternative embodiment, two current elements located opposite from one another in a radio frequency magnetic field unit are removed to form a magnetic filed unit having a first side aperture and a second side aperture.

Abstract: An RF coil suitable for use in imaging systems is provided which coil has a dielectric filled cavity formed by a surrounding conducting enclosure, the conducting enclosure preferably being patterned to form continuous electrical paths around the cavity, each of which paths may be tuned to a selected resonant frequency. The patterning breaks up any currents inducted in the coil and shortens path lengths to permit higher frequency, and thus higher field strength operation. The invention also includes improved mechanisms for tuning the resonant frequency of the paths, for selectively detuning the paths, for applying signal to the coil, for shortening the length of the coil and for controlling the field profile of the coil and the delivery of field to the object to the image.

Abstract: A current unit having two or more current paths allows control of magnitude, phase, time, frequency and position of each of element in a radio frequency coil. For each current element, the current can be adjusted as to a phase angle, frequency and magnitude. Multiple current paths of a current unit can be used for targeting multiple spatial domains or strategic combinations of the fields generated/detected by combination of elements for targeting a single domain in magnitude, phase, time, space and frequency.

Abstract: An excitation and detection circuit having individually controllable elements for use with a multi-element radio frequency coil. Characteristics of the driving signal, including, for example, the phase, amplitude, frequency and timing, from each element of the circuit is separately controllable using small signals. Negative feedback for the driving signal associated with each coil element is derived from a receiver coupled to that coil element.

Abstract: An EGR valve apparatus regulates the amount of exhaust gas recirculated in an EGR system. The EGR valves are opened or closed by a rotatable shaft which is actuated by a motor. Alternatively, the valves can be balanced on the shaft, the valves moving in opposing direction during rotation. An inline poppet can be employed to overcome pressure in the system prior to movement of the valves. In another alternative embodiment, the motor rotates threaded shaft to move a pintle towards and away from an orifice.

Abstract: Human antibodies, preferably recombinant human antibodies, that specifically bind to human tumor necrosis factor &agr; (hTNF&agr;) are disclosed. These antibodies have high affinity for hTNF&agr; (e.g., Kd=10−8 M or less), a slow off rate for hTNF&agr; dissociation (e.g., Koff=10−3 sec−1 or less) and neutralize hTNF&agr; activity in vitro and in vivo. An antibody of the invention can be a full-length antibody or an antigen-binding portion thereof. The antibodies, or antibody portions, of the invention are useful for detecting hTNF&agr; and for inhibiting hTNF&agr; activity, e.g., in a human subject suffering from a disorder in which hTNF&agr; activity is detrimental. Nucleic acids, vectors and host cells for expressing the recombinant human antibodies of the invention, and methods of synthesizing the recombinant human antibodies, are also encompassed by the invention.

Abstract: An exhaust gas recirculation (EGR) cooling system includes a valve and a cooler. A motor opens the valve allowing hot fluid exhaust gas to flow into the valve. Cooling fluid continuously flows in and circulated around the valve, reducing the amount of heat transfer from the hot fluid to the valve components. The hot fluid travels through a plurality of tubes in the cooler, continuing to transfer heat to the cooling fluid. As the hot fluid is cooled, the unburned gas in the hot fluid is recycled to be burned by the engine.

Abstract: A via termination for a microstrip transmission line formed on a substrate includes a termination resistor that connects an end of the signal conductor to a backside ground plane through a via. Two open-circuit stubs are also formed on the first face of the substrate, one stub on each side of the termination resistor. A compensation resistor on the first face of the substrate connects the end of the signal conductor to each open-circuit stub. The load resistor is equal to the characteristic impedance of the transmission line and the compensation resistors are each equal to twice the characteristic impedance. The combined termination ideally exhibits a real impedance equal to the characteristic impedance over a wide frequency range.

Abstract: A compact waveguide coupler or mixer having and an input, an output and a plurality of transmission segments coupled between the input and output. The transmission segments are preferably formed such that at least one is configured in a transmission media that permits conductor switching to achieve a phase shift. In a preferred embodiment, this media is slot line strip and the at least one conductor has a quarter wavelength and includes a conductor switch that achieves a 180 degree phase shift, thereby forming, in combination, a conduction segment that induces an approximately 270 degree phase shift. Various compact conductor arrangements are presented as are mixer and coupler embodiments.

Abstract: An exhaust gas recirculation system for an internal combustion engine including a valve body having an exhaust port adapted for fluid communication with a source of exhaust gas, an intake port adapted for fluid communication with the intake manifold of an internal combustion engine, and a valve member movably supported within the body between open and closed positions thereby controlling the flow of exhaust gas from the exhaust port to the intake port. A diaphragm housing is operatively mounted to the valve body and supported thereby. The diaphragm housing defines a vacuum cavity in fluid communication with a source of negative pressure and an atmosphere cavity in fluid communication with a source of second pressure. A diaphragm member is disposed between the vacuum and atmosphere cavities and is operatively connected to the valve member.

Abstract: A means of connecting a plurality of essentially identical active devices is presented for the purpose of multifunction and multiple function operation. These devices, mounted on a chip, are flip-mounted onto a circuit formed on a base substrate and having large passive elements. Push-pull amplifiers are presented as examples in which the multiple function operation is the combining of amplifiers whose active devices are on a single chip. Electromagnetic coupling, impedance matching and signal transmission are variously provided by the use of strip lines, slotlines, coplanar waveguides, and a slotline converted into a coplanar waveguide.
