Methods are provided for coating crystalline microparticles with an active agent by altering the surface properties of the microparticles in order to facilitate favorable association on the microparticle by the active agent. For each monitored frequency channel, an active mask is initialized. The break-away lock includes a swivel connected to the fire hydrant, a slide-out coupler, one end of which is connected to the water meter and the opposite end of which is slideably received by the swivel, and an outer clamping shell surrounding the swivel and slide-out coupler to deny unauthorized access thereto. The electrical circuit includes means for, during start-up of the compressor assembly, initiating the supply of electrical current to the first motor at a first time and initiating the supply of electrical current to the second motor at a second time wherein the first time precedes the second time by a time lapse. The housing further includes a rectangular receiving portion and two stopping portions formed at least one pair of opposite lateral edges of the receiving portions. Based on the calculated code transmit power, transmit power for each transmit antenna is allocated.
