Abstract: A device comprises a coupling configured to couple signals to and from a communications path including at least a part of a human or animal body; a data transmitter coupled to the coupling and configured to transmit, from time to time, a data signal of at least a predetermined temporal duration via the communications path; and a data receiver coupled to the coupling and configured to detect the presence of a signal on the communications path at sets of one or more successive detection instances disposed between successive transmissions of the data signal by the data transmitter, the data receiver being configured so that the successive detection instances of a set are temporally separated by no more than the predetermined temporal duration; the device being configured to initiate a processing operation in response to a detection by the data receiver of the presence of a signal on the communications path.

Abstract: A method of manufacture of a liquid pesticide containing copper. A first step involves forming of a solidified water soluble copper-borate complex. A second step involves dissolving the solidified water soluble copper-borate complex in water, until the water contains a concentration of at least 0.02% by weight of copper.

Abstract: A method of treating building materials with boron and boron treated building materials. The method involves introducing boron during manufacture of the building materials in the form of a water soluble copper-borate complex. The copper-borate complex enables a wider range of glues and adhesives to be used, is slower to leach out, and provides enhanced fungicidal properties.
