| PURPOSE: An inlet solenoid valve for an anti-lock brake system, a traction control system, and an electronic stability program is provided to minimize the number of parts by forming a housing, a sleeve, and a bushing as one body through injection molding, and to improve braking power through improvement of response property. CONSTITUTION: An inlet solenoid valve for an anti-lock brake system, a traction control system, and an electronic stability program comprises a housing(20) connected to an inflow port(11); a valve seat(60) mounted inside the housing; a first fitting projection(63) formed to the outer peripheral surface of one end of the valve seat; a ring piston(70) forming a second fitting projection(71) touched with the first fitting projection; a spring(100) positioned inside the ring piston; an armature(90) supporting the other side of the spring; and a plunger(80) received in the armature and the valve seat. The housing forms an aperture on a side and forms an outflow hole(22) in the center, to be connected to an outflow port(12). The valve seat forms an opening and shutting hole(62) connected to the aperture and forms a passage hole(61), to connect the opening and shutting hole and the outflow port. The ring piston is formed as a magnetic material. One side of the spring is supported to the first fitting projection. The armature comprises a magnetic body received in the housing. The plunger forms a protruded part to open and shut the opening and shutting hole. | ||||||

Systems and methods of enhancing crude oil recovery include radiating electromagnetic energy in the form of focused electromagnetic pulses into a permeable formation containing the crude oil and/or fluid via an array of antennae transmitting immediately in the far field. The electromagnetic pulses are focused at the depth of the fluid reservoir. Pulses will be reflected by the fluid according to the fluid material (e.g. oil vs. water) and/or the strata (e.g. rock, sand, etc.). An array of receiver antennae may be used to initially establish a reference of the reflected electromagnetic pattern, and then operated in conjunction with the transmit array to monitor the relative horizontal movement of oil and/or water within the subterranean reservoir. |

| A solution to the electromagnetic position/orientation tracking problem is presented in an environment wherein strong electromagnetic distortion may be present includes at least one source of an AC electromagnetic field, at least one witness sensor (503) measuring components of the electromagnetic induction vector at known spatial points close to or within the volume of interest, at least one wireless probe sensor (502) placed on the object being tracked, and a control and processing unit (504). The wireless sensor (502) has a known response or distortion to the electromagnetic field generated by the primary source. The control/processing unit (504) uses data from the witness sensor(s) to locate the probe sensor (502) as a secondary source of the AC electromagnetic field; that is, as a transponder with initially known magnetic parameters. This information is utilized by a position and orientation algorithm executed by the control/processing unit to define coordinates and attitude of the secondary source and, in turn, the position and orientation of the object of interest. In the preferred embodiment, the probe sensor (502) is an LC-contour tuned to the frequency of the tracker source. As such, the signal from the probe sensor is 90 DEG phase shifted with respect to the tracker source signal and other signals in the system, including distortion. This allows the witness sensors (503) and processing unit (504) to separate the environmental distortion signal from the probe sensor signal by distinguishing the phase of the signal from the probe sensor. | ||||||
