Abstract: The present invention relates to an analytical device and reaction chamber therefor. Specifically it relates to a device comprising a chamber with lobes configured such that altering the lobe configuration aids in the analytical interrogation of a portion of the fluid within the chamber.

Abstract: The present invention relates to a method of preparing a sample for subsequent use in a diagnostic or analytical assay by concentrating the target analyte and/or removing interfering factors from the sample matrix. The present invention also relates to a fluidic device comprising a capture and release system connected to an immunodetection system.

Abstract: A connector for board-to-board and board-to-device interconnect applications includes a plurality of conductive elastomeric columnar contacts arranged in a contact array and retained in a first plurality of openings in an insulative substrate and a plurality of stops retained in a second plurality of openings in the insulative substrate. The stops are dispersed among the contacts of the contact array or positioned on the periphery of the contact array and located in non-abutting relation with respect to adjacent contacts. The contacts and the stops have opposing end surfaces and the end surfaces of the contacts are located a greater distance from the substrate than the end surfaces of the stops such that the stops limit the compression of the elastomeric contacts when the connector is disposed in its intended mounting orientation.

Abstract: A socket for a BGA package is provided which is of relatively simple construction and which provides reliable and efficient interconnection of a BGA package and a printed circuit board. The socket comprises a contact assembly having an array of resilient conductive columns having respective contact ends, the columns being mounted on a thin insulative sheet. The contact assembly is supported on a frame of insulating material and which has alignment posts for alignment of the contact assembly to the frame and for alignment of the frame and mounted contact assembly to an associated circuit board. The frame also includes latch elements for retaining the contact assembly on the frame. The socket is mounted onto a printed circuit board which has an array of contact areas corresponding to the array of resilient contacts of the socket.
