Abstract: A method and system for providing information to a user positioned in a room with two independent listening areas where, in one area, an audio signal is output compensating for the sound from the other area, and where a position between the two areas is indicated to a user. When the user moves about, the position and size of one listening area may change, and the user may be made aware of any conflict with the other listening area. The areas may be defined by boundaries where a compensation quality is at a threshold quality.

Abstract: The present invention discloses a Gram negative bacterium in which the expression of a protein involved in LPS transport to the outer membrane is functionally downregulated such that the level of LPS in the outer membrane is decreased compared to a wild-type Gram negative bacterium. Down regulation of Imp and MsbA proteins can result in such a bacterium. Outer membrane vesicle preparations derived from the Gram negative bacterium of the invention can be used in vaccines to provide protection against bacterial infection.
