Patent number: 7937139Abstract: The present invention relates to a system for determining treatment options from at least two electrical readings. The electrical readings are conductivity measurements of a particular region on the human body. The system utilizes a correlation algorithm to determine the diagnosis which can easily be correlated with appropriate treatments. The correlation algorithm may include the analysis of multiple electrical readings in determining the diagnosis. The system may also utilize a database of clinical data to further assist in determining the diagnosis.Type: GrantFiled: July 20, 2004Date of Patent: May 3, 2011Assignee: BioMeridian International, Inc.Inventors: Douglas S. Horne, Phillip Dietz, Harold E. Swift, Valentine C. Krzyzaniak, Jacob L. Carter, Bruce R. Shelton

Patent number: 7542796Abstract: The present invention is a method for obtaining an electrical signal from a patient that corresponds to a meridian. The present method contemplates locating a dermal area of a patient proximate a meridian. One embodiment of the present invention comprises locating a dermal area by iteratively measuring and comparing the conductivity of a patient's skin until a significant level of conductance is indicated. A probe may then be placed in contact with the dermal area, and actuated to obtain an electrical signal therefrom. The probe tip may be specially designed to apply an appropriate amount of pressure to the dermal area to directly sense a meridian, and configured to avoid erroneous measurements resulting from misalignment of the probe or probe tip.Type: GrantFiled: July 16, 2003Date of Patent: June 2, 2009Assignee: BioMeridian International, Inc.Inventors: Douglas S. Horne, Phillip Dietz, Harold E. Swift

Patent number: 7026511Abstract: A process to produce N-vinylformamide includes the steps of: reacting hydroxyethyl formamide with a reactant comprising at least one cyclic anhydride group to form an ester, and dissociating the ester via heat in a thin film evaporation to synthesize N-vinylformamide and a compound comprising at least one diacid group, the N-vinylformamide separating from the diacid during the thin film evaporation. The reactant including at least one cyclic anhydride group can, for example, be succinic anhydride, maleic anhydride, phthalic anhydride, (2-docecen-1-yl)succinic anhydride, exo-3,6-epoxy-1,2,3,6-tetrahydrophthalic anhydride or a polymer including at least one cyclic anhydride group.Type: GrantFiled: February 27, 2004Date of Patent: April 11, 2006Assignees: University of Pittsburgh, SNF SAInventors: Eric J.

Patent number: 6965052Abstract: A process to produce N-vinylformamide includes the steps of: reacting hydroxyethyl formamide with a reactant including at least one cyclic anhydride group to form an ester, and dissociating (or cracking) the ester to synthesize N-vinylformamide and a compound including at least one diacid group. The ester can be dissociated using heat. The reactant including at least one cyclic anhydride group can, for example, be succinic anhydride, maleic anhydride, phthalic anhydride, a polymer including at least one cyclic anhydride group, or a solid support to which at least one cyclic anhydride group is covalently tethered. Preferably, the cyclic anhydride is regenerated from the diacid formed in the synthesis of the ester by heating the diacid to dehydrate the diacid. The temperature required to dehydrate diacid groups is preferably higher than the temperature use to dissociate the ester.Type: GrantFiled: August 29, 2003Date of Patent: November 15, 2005Assignees: University of Pittsburgh, SNF SAInventors: Eric J.

Patent number: 6086669Abstract: Describes a free flowing particulate composition comprising, in combination, particulate amorphous precipitated silica, e.g., in the form of granules, hydrocarbon process oil, e.g., an aromatic process oil, and organic carboxylic acid having from 2 to 30 carbon atoms, e.g., stearic acid. The hydrocarbon process oil and organic carboxylic acid are sorbed on the silica and are present in amounts sufficient to measurably improve the dispersibility of the particulate amorphous precipitated silica into an elastomer as measured by percent white area. Optionally, an organosilane coupling agent may also be present in said composition. The free flowing particulate composition of the present invention is useful in reinforcing elastomers, e.g., rubbers used in vehicle tires and the soles of athletic foot wear.Type: GrantFiled: April 9, 1998Date of Patent: July 11, 2000Assignee: PPG Industries Ohio, Inc.Inventors: Shailesh D.

Patent number: 4434281Abstract: There is provided a solid, particulate, catalytic complex suitable for the stereospecific polymerization of olefins prepared by reducing TiCl.sub.4, contacting the resultant reduced solid with a complexing agent to obtain a treated solid and contacting the treated solid with TiCl.sub.4 in the presence of silica which has been treated with an alkylaluminum halide. When such a catalyst complex is combined with a suitable activator to polymerize olefins, a high degree of stereospecificity is attained, the activity of the catalyst complex is reduced for polymerization control and the efficiency of the titanium employed is enhanced.Type: GrantFiled: October 19, 1982Date of Patent: February 28, 1984Assignee: Gulf Research & Development CompanyInventors: Harold E.
