Method and apparatus for optimization of wireless multipoint electromagnetic communication networks

Exploiting the substantive reciprocity of internode channel responses through dynamic, adaptive modification of receive and transmit weights, enables locally enabled global optimization of a multipoint, wireless electromagnetic communications network of communication nodes. Each diversity-channel-capable node uses computationally efficient exploitation of pilot tone data and diversity-adaptive signal processing of the weightings and the signal to further convey optimization and channel information which promote local and thereby network-global efficiency. The preferred embodiment performs complex digital signal manipulation that includes a linear combining and linear distribution of the transmit and receive weights, the generation of piloting signals containing origination and destination node information, as well as interference-avoiding pseudorandom delay timing, and both symbol and multitione encoding, to gain the benefit of substantive orthogonality at the physical level without requiring actual substantive orthogonality at the physical level.

Method and apparatus for separating particles by size

A method and apparatus for separating a mixture of particles of various sizes in a capillary tube into groups by size using multiple forces of controlled amplitude. Ultrasonic radiation at a first selected frequency is applied to set up a standing pressure wave in the capillary tube, resulting in a first aggregating force which causes particles of all sizes to aggregate at positions within the capillary tube which correspond to nodes or anti-nodes of the standing wave. Transverse vibrations are also applied to the capillary tube. The frequency of the ultrasonic radiation is adjusted to reduce the magnitude of the first aggregating force. Inertial forces resulting from the transverse vibrations then cause the particles to separate by size. The apparatus and method allows a mixture of particles to be separated by size quickly, without requiring the use of high voltages.
