  • Patent number: 11428657
    Abstract: A sensor for measuring electrochemical impedance includes a primary circuit that includes a primary electrically conducting coil and a secondary circuit that includes a secondary electrically conducting coil. The primary electrically conducting coil is inductively coupled to the secondary circuit. During operation, the secondary electrically conductive couple has contact electrodes that contact a medium for which the impedance is to be measured. An alternating current source energizes the primary electrically conducting coil during impedance measurements.

  • Patent number: 8895020
    Abstract: Single chain trimer (SCT) molecules are disclosed, comprising an MHC antigen peptide sequence, a ?2-microglobulin sequence and a full-length MHC class I heavy chain sequence, joined by linker sequences. Further described are nucleic acids encoding single chain trimers. Methods for expansion of antigen-specific T cell populations using single chain trimer molecules are also disclosed. In some configurations, these methods comprise co-culturing, in a first stage, CD8+ T cells from a donor with antigen presenting cells comprising an MHC antigen peptide, and co-culturing, in a second stage, the CD8+ T cells with cells comprising an SCT which has an MHC antigen peptide sequence identical to the sequence of the antigen peptide in the first stage. The methods can provide 10,000-100,000 fold expansion of antigen-specific CD8+ T cells within about 28 days after establishing culture, and can yield over 1 billion antigen-specific CD8+ T cells expanded from an individual donor.

  • Publication number: 20030211782
    Abstract: A filtered RJ11 connector module that is adaptable for mounting on Home Phone Networking Alliance (HPNA) network interface card useful for home networking applications and other communication protocols involves the integration of filter module into the connector module itself. The filter module comprises an isolation transformer, common mode choke, filter components, high voltage capacitor and surge protection device that may be configured to customize any network interface card. Mounting of at least two light indicators on a printed circuit board is another embodiment of the invention and therefore, also an integral part of a filtered RJ11 connector module. The housing consists of at least one plug-receiving opening for receiving connector plugs that are electrically connected to a transmission medium.

  • Patent number: 5339898
    Abstract: The invention involves combining a plurality of vertical wells, each having a power conditioning unit located on the surface and an electrode in electrical contact with the reservoir, with a horizontal well extending through the reservoir in spaced relation to the vertical wells. The liner and tubing of the horizontal well function as the common return means for the circuit. Low frequency current is supplied to flow between the vertical and horizontal wells at adequate levels so as to cause heating in the near-wellbore regions of all the wells. Oil is produced, at the same time as electrical heating, at enhanced rates as a result.
