blot as much urine up as you can- if it's still wet (doesn't matter) mix vinegar & water in a spray bottle (40/60 or any strong combo will do)- soak entire area. let sit a while then coat with baking soda- let sit again. scrub with hand brush- take up with paper towels.
Hernia mesh is a product which is used in hernia repair. It is made from implant-grade plastics which are formed into a grid which can be used at the site of a hernia to hold herniated organs in place and provide a lattice for new tissue to grow on, effecting a long term repair at the site.
Well, it definitely uses a mesh network: http://www.firstalert.com/faqs/onelink/what-is-a-mesh-network-and-how-does-it-work. But there isn't any data on which mesh network it uses. According to this link: http://www.lowes.com/cd_How+Iris+Works_379038320_ Iris uses Zigbee, Zwave, and WiFi. I think it's safe to assume these detectors are NOT using Wifi, so it's gotta be one of the Z's.
