Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

G06F 1100

US Classification:

375224

Abstract:

A method for testing communication channels of a satellite using a 16-bit n-length compression algorithm wherein the most significant bit (MSB) is used to represent the errored or not errored condition of the compression algorithm. Error patterns are read and downloaded into a PC interface card which decompresses the file real time and passes the error pattern to a bit error rate summer board. The bit rate summer board overlays the error pattern onto the communication links of the satellite which causes precise bits to be errored accordingly.

Abstract:

Methods of treating water to promote the health of aquatic organisms are described. The method may include introducing pulverized kaolin into the water. The pulverized kaolin may have a particle size distribution such that at least 30% by weight of the particles pass through a 60 mesh screen. For example, the pulverized kaolin may be in the form of a dry powder having a ddiameter less than 300 μm. The pulverized kaolin may remain dispersed or suspended in the water without dispersants and/or surfactants, e.g., to reduce the amount of at least one pathogenic microorganism present in the water and/or to reduce or prevent exposure of aquatic organisms to the pathogenic microorganism(s).
