Patent number: 5675551Abstract: Apparatus and method are disclosed for use with a horizon picking method for 3D seismic data. Variables such as picking method, whether simple or iterative, score required of an iterative method and .DELTA.T between target wavelets and seed wavelet are input into the computer. During the picking process, parameters as to the number of successful picks and the number of failed picks because of the method of picking and because of failed picks due to the score not being achieved in the iterative method and because of failed picks due to the difference in time between the target wavelet and the seed wavelet being greater than the .DELTA.T variable are recorded. The number of score failures to pick a target wavelet from a seed wavelet is recorded where the score achieved is less than the input score. A characteristic of such number of score failures, such as the percentage of score failures to the total number of picking tries, is displayed on a CRT screen.Type: GrantFiled: April 17, 1996Date of Patent: October 7, 1997Assignee: Landmark Graphics CorporationInventor: Mun K.

Patent number: 5664577Abstract: Apparatus and method for the recording of distortion product emission (DPE) levels in human beings. At least one microphone and a sound-delivery system is inserted in the external ear canal. Two primary tones T.sub.f1, T.sub.f2 are applied simultaneously to the ear. The cochlea of the inner ear produces a DPE tone which is sensed by the microphone. DPE levels are sensed as a function of input frequencies f.sub.1 and f.sub.2. Such DPE frequency is equal to 2f.sub.1 -f.sub.2. Such DPE frequencies are collected in 100 Hz step by adjusting f.sub.1 and f.sub.2 and maintaining a substantially constant ratio between f.sub.1 and f.sub.2. Two output forms are created: an DPE audiogram and a DPE input/output function. Noise picked up is reduced by averaging the DPE signals many times, yet causing each of the DPE signals that is averaged to be of the same phase a every other DPE signal. Random phase noise is reduced by the averaging process.Type: GrantFiled: June 13, 1996Date of Patent: September 9, 1997Assignee: Baylor College of MedicineInventors: Brenda L. Lonsbury-Martin, Glen K. Martin

Patent number: 5658227Abstract: An exercise device (10) has a handlebar (30) with handgrips (32) for gripping by a user (U). An adjustment plate member (26) is mounted for pivotal movement about a pivot (28) on a fixed support plate member (18). A seat (58) supports the weight of the user U to resist to the rotation of the adjustment plate (26). A generally horizontal exercise movement is performed by pulling on the handlebar (30) and simultaneously pushing on foot pedals (70) on a foot frame (68) secured to the adjustment plate member (26). The horizontal exercise movement shown in FIGS. 1 and 2 can be easily converted to a vertical exercise movement shown in FIG. 3 at the discretion of the user (U) by changing the motion exerted against the handlebar (30) by the user (U).Type: GrantFiled: September 12, 1995Date of Patent: August 19, 1997Assignee: Stearns Technologies, Inc.Inventor: Kenneth W.

Patent number: 5621169Abstract: A method for predicting the hydrocarbon/water contact level for oil and gas wells which relates porosity .phi., water saturation S.sub.w, air permeability k.sub.a, and capillary pressure P.sub.c. Such contact level may be estimated without actual capillary pressure measurements. The method relies on a worldwide correlation of permeability and porosity to a function of capillary pressure. The hydrocarbon/water contact levels are predicted through regression analysis using porosity .phi., water saturation S.sub.w, and air permeability k.sub.a from well log and core analysis information. Relationships used in this method include ##EQU1## where P.sub.c is mercury capillary pressure, F.sub.g is pore geometrical factor, S.sub.w is water saturation, P.sub.d is mercury displacement pressure, k.sub.a is air permeability, and .phi. is porosity. The constants set forth in equations (b) and (c) above may be adjusted to fit measured data from rock samples within the reservoir.Type: GrantFiled: September 10, 1996Date of Patent: April 15, 1997Assignee: Restech, Inc.Inventors: Thomas G.
