A battery module of the present invention comprises an annular connecting member 10 having an aperture 14 at a position corresponding to a cap 8 provided on a sealing plate 7 and between the sealing member 7 of one cell B and a bottom of a can 6 of the other cell A. The system and method use a symmetric and reflexive function to allow for linking records and entity representations whose field values differ. In addition this approach can be used to identify new indications for existing medicines and new indications for NCEs that were unsuccessful in their intended uses. The pan-handle holder further includes a biasing mechanism for holding the first and second complimentary sections apart. The decoupling device can have offset apertures provided by plates or rods or other comparable arrangements, or can comprise a quadrupolar electrostatic deflector, an electrostatic sector deflector or a magnetic sector deflector.
