"Hygro-Wick" is a fiberglass insulation that prevents condensation on piping systems used below ambient temperature. Insulation failure is inevitable for most chilled water piping, because of moisture damage. But Hygro-Wick uses a super-absorbent hydrophillic wicking cloth at its core, to move moisture to the outside of the system, where it evaporates.

The Torque Activated AM Signal Wrench (TAAMS) is a wireless fastener system that operates on AM frequency, with multiple channel and tool tracking capability in a single unit. It has a small, battery-powered transmitter in its handle, so when a pre-set torque is reached, the tool sends an AM signal to a receiver unit that records the fastener as fastened. Its design avoids both restrictive cables and unreliable FM signals.
