Abstract: A method of removing contaminants from an aqueous material, the method comprising the steps of: providing an aqueous material comprising one or more non-particulate contaminants; and filtering the aqueous material to remove at least part of the one or more non-particulate contaminants to form a recovered portion of the aqueous material in which the amount of contaminant is reduced to an amount allowing re-use of the recovered portion of the aqueous material, wherein filtering the aqueous material includes passing the aqueous material across a partially permeable membrane at a temperature higher than 50° C.

Abstract: A wireless tunneling system tunnels communications between a first host device and a second host device through a wireless link, while maintaining compliance of the communications between the first and second host devices with a wired communication protocol and operates in a power efficient manner. Two host devices may communicate with each other through a wireless link using the wireless tunneling system, as if two host devices were connected through the wired cable. The wireless tunneling system operates in one of a high power state and one or more low power states. In the high power state, the wireless tunneling system exchanges data at a higher data rate for tunneling. In the low power state, the wireless tunneling system disables power hungry components for conserving power.
