Abstract: A gas analyzer includes a housing adapted for insertion into a chamber. The housing has an open interior with a chemochromic sensor assembly arranged therein which includes a chemochromic media, an electronic color sensor that senses a color of the chemochromic media, and a processor. In operation, the housing is inserted into a chamber, the chemochromic media is exposed to a gas within the chamber, the chemochromic media changes color depending on the gas within the chamber, and the electronic color sensor detects the color of the chemochromic media and communicates a signal to the processor based on the detected color. The processor may be configured to generate gas detection information based on the signal received from the electronic color sensor. A transmitter in communication with the processor communicates at least a portion of the gas detection information from the chemochromic sensor assembly to remote monitoring equipment.

Abstract: A structural liner for reinforcing existing underground water conduits to resist earthquakes and landslides adapted for insertion into underground water conduits without having to excavate are disclosed. The reinforcement structural device consists of a seamless woven tubular sheath impregnated with a hardening resin which is adapted for insertion into a network of underground water conduits without the need to excavate. The seamless woven tubular sheath consists of continuous longitudinal fiber warp yarn providing tensile strength along the longitudinal axis of the woven tubular sheath and circumferential fiber filling yarn providing tensile strength around the wall of the woven tubular sheath.

Abstract: A forehead clearing apparatus having a pair of wedge shaped modules comprising hook and pile strips wherein the pile strip has a peel and stick backing which is glued onto the headband of a hat or cap and the hook strip is permanently bonded to the wedge shaped module so that the wedge shaped modules are readily removable.
