Patent CA-2006474-C (CA)
Title: Geminal diphenyl derivatives and their use in immunoassays
Inventor: SCHULKAMP KIRK
IPC: G01N33/53
Filed: 1989-12-21
Granted: 2000-02-22
Abstract: Methods are disclosed for inactivating interfering binding proteins in a immunoassay for a member of a specific binding pair (sbp). The method comprises including in an assay medium containing a sample suspected of containing an sbp member and an interfering binding protein an effective amount of a water soluble compound having two substituted or unsubstituted phenyl groups linked to a common atom. When the sbp member or its sbp partner has two phenyl groups linked to a common atom, the compound has a number of groups other than hydrogen attached to the phenyl groups and the atom that differs by at least two from the number of such groups on the sbp member. When the sbp member or its sbp partner has two phenyl groups linked to a common atom and the binding protein is not an antibody, the compound has only one group other than hydrogen attached to a phenyl group or the common atom. The methods have particular application in avoiding cross-reactivity of non-analyte materials in a sample with immunochemical reagents used in such assay. The methods have application also in disrupting complexes between an analyte to be determined and other materials so that one can accurately determine the amount of an analyte in a sample.

Title: Method for assigning telecommunications channels in a cellular telephone system
Inventor: BENNER FRANK D
IPC: H04B7/26
Filed: 1990-08-10
Granted: 1994-06-28
Abstract: A method of assigning frequencies in a cellular telephone  system  in which  a  first  group  of  the available frequencies is assigned to a first cell, and then distinct groups are assigned to adjacent cells, leaving at least one distinct group of frequencies free for later re-use. This system is applied to each cell in the system, so that for any cell, it and its adjacent cells do not use all of the frequencies in the system.  For a first stage of cell splitting, frequencies  are  assigned  from  at  least  one  non-adjacent cell (using the frequency re-use groups) to at least one part of the cell being split,  while maintaining coverage of the cell from the same cell site. In a further stage of cell splitting in which there are adjacent first and second sets of three co-located  end  radiated  cells,   each  radiated  by directional antennas at first and second cell sites respectively, the cells are split by: locating a third cell site at about the mid-way point between the first and second cell sites; and radiating at least a third cell from the third cell site. An example is given based on 9 cells with sites arranged for end radiation of 3 cells from one site, thus reducing the number of cell sites.  At each site the 3 co-located cells use frequency groups spaced to give protection against adjacent  channel  interference.    The  use  of  end radiated   cells   allows   for   less   co-channel interference, as well as providing for a more distinct handoff between cells.
