Abstract: A method for detecting and/or quantifying a target DNA or RNA present in a sample by a isometric primer extension method is disclosed. The method includes carrying out a primer extension reaction in the absence of a free nucleotide so that the primer extension reaction is stopped where the absent nucleotide would have been inserted. Thus, as the amount of incorporation of a labeled nucleotide on the primer extended product is detected, the amount of the target RNA or DNA in the sample is measured.

Abstract: The present invention provides a novel process and its required fluxable materials for building low-cost flip-chip interconnect structures. The novel process involves two fluxable materials, fluxable wafer-level compressive-flow underfill material (WLCFU) and fluxable tacky film, and applies these two materials on a wafer level. The two materials can provide sufficient fluxing capability during solder reflow and significant improvement of the fatigue life of the formed solder interconnects after fully cured.

Abstract: A method of joining electrically conductive materials comprises: Applying an electrically conductive adhesive to at least one electrically conductive material(s), wherein the electrically conductive adhesive is prepared from an epoxide-modified polyurethane, a cross-linking agent, an adhesion promotor and a conductive filler; and joining the electrically conductive material(s) with the applied adhesive to a substrate and curing the adhesive.

Abstract: The present invention is directed to polymer-ceramic composites having high dielectric constants formed using polymers containing a metal acetylacetonate (acacs) curing catalyst. In particular, it has been discovered that 5 weight percent Co(III) acac can increase the dielectric constant of DER661 epoxy by about 60%. The high dielectric polymers are combined with fillers, preferably ceramic fillers, to form two phase composites having high dielectric constants. Composites having about 30 to about 90% volume ceramic loading and a high dielectric base polymer, preferably epoxy, have been discovered to have a dielectric constants greater than about 60. Composites having dielectric constants greater than about 74 to about 150 are also disclosed. Also disclosed are embedded capacitors with capacitance densities of at least 25 nF/cm2, preferably at least 35 nF/cm2, most preferably 50 nF/cm2. Methods to increase the dielectric constant of the two phase composites having high dielectric constants are also provided.

Abstract: A reworkable epoxy underfill is provided for use in an electronic packaged system which incorporates an integrated circuit, an organic printed wire board, and at least one eutectic solder joint formed therebetween. An exemplary embodiment of the encapsulant includes: a cycloaliphatic epoxide; an organic hardener; and a curing accelerator; wherein said cycloaliphatic epoxide includes a carbonate or carbamate group. The encapsulant can also include a filler, such as a silica filler. A method is also provided for forming the aforementioned reworkable epoxy underfills.

Abstract: An eraser for use on an electronic whiteboard with a protrusion area on the erasing surface forming a convex area on the erasing surface for establishing a positive point of contact with the whiteboard; an electronic whiteboard system including such an eraser, a controller for storing data relating to information written on and erased from the whiteboard data, and a filter for preventing the storage of digital data relating to contacts with the whiteboard not attributable to normal writing or erasing actions.

Abstract: A method for determining blood glucose levels by measuring the glucose concentration in the ocular aqueous humor using optical refractometry by passing laser light the aqueous ocular humor, measuring the laser light's optical refractivity, and comparing the refractivity with known data, the comparison yielding the blood glucose level.

Abstract: A stream conditioning system for a fuel cell gas management system or fuel cell engine. The stream conditioning system manages species potential in at least one fuel cell reactant stream. A species transfer device is located in the path of at least one reactant stream of a fuel cell's inlet or outlet, which transfer device conditions that stream to improve the efficiency of the fuel cell. The species transfer device incorporates an exchange media and a sorbent. The fuel cell gas management system can include a cathode loop with the stream conditioning system transferring latent and sensible heat from an exhaust stream to the cathode inlet stream of the fuel cell; an anode humidity retention system for maintaining the total enthalpy of the anode stream exiting the fuel cell related to the total enthalpy of the anode inlet stream; and a cooling water management system having segregated deionized water and cooling water loops interconnected by means of a brazed plate heat exchanger.

Abstract: A method to analyze and diagnose specific bacteria in a biologic sample using spectroscopy is disclosed. The method includes obtaining the spectra of a biologic sample of a non-infected patient for use as a reference, subtracting the reference from the spectra of an infected sample, and comparing the fingerprint regions of the resulting differential spectrum with reference spectra of bacteria in saline. Using this diagnostic technique, specific bacteria can be identified sooner and without culturing, bacteria-specific antibiotics can be prescribed sooner, resulting in decreased likelihood of antibiotic resistance and an overall reduction of medical costs.
