20090120795	Apparatus And Methods For Concentrating And Separating Particles Such As Molecules - Particles of interest, such as DNA molecules, are injected into a medium by applying a first field. Once in the medium the particles are concentrated by applying one or more fields that cause mobilities of the particles in the medium to vary in a manner that is correlated with motions of the particles. Particle injection and particle concentration may be performed concurrently or in alternation.	05-14-2009

20110048950	METHODS AND APPARATUS FOR PARTICLE INTRODUCTION AND RECOVERY - Particles may be injected into a matrix for concentration by scodaphoresis using a quadrupole injection field. Particles may be injected from two or more sample chambers simultaneously. Particle injection may be performed simultaneously with performing scodaphoresis. In some embodiments the particles are concentrated into a well containing fluid. The well can extend out of a plane of the matrix. Altering the relative phases of components of a scodaphoresis field permits concentration of selected particles and exclusion of other particles. Scodaphoresis methods may be applied to DNA, other bio-molecules and other particles.	03-03-2011

20090020983	Towable wheeled vehicle having a steering axle - A towable wheeled vehicle releasably attachable to a towing vehicle at two horizontally spaced apart points provides a frame supporting a deck, a wheel carriage having a leaf spring suspension and a tubular steering axle with rotatable and turnable wheels at each end, and an electrically powered pneumatic system. Airbags communicating between the steering axle and the frame inflate and deflate to axially rotate the steering axle in axle sleeves carried by the leaf spring suspension reversing the caster and camber of the wheels responsive to activation of the towing vehicle's back up lights.	01-22-2009
