Abstract: A method for detecting a gaseous substance in a gas-mixture, a first measuring-variable which represents a first chemical and/or physical parameter of the gas-mixture being acquired, at least one second measuring-variable which represents a second chemical and/or physical parameter of the gas-mixture that differs from the first parameter being acquired, and a starting-measuring-instant, corresponding to the starting-instant, of the first parameter is specified when an amount of a time-derivative of the first measuring-variable exceeds a first predefined threshold-value and an amount of a time-derivative of the second measuring-variable exceeds a second predefined threshold-value, and at least one further first measuring-variable is acquired, an end instant is specified when the at least one further first measuring-variable corresponds to the starting measuring-variable, and an output signal is generated when the amount of a difference between the end instant and the starting instant is greater than a predefin

Abstract: Technology is disclosed for tsunami survival shelters. In various embodiments, a tsunami survival shelter comprises a vertical support column designed to withstand forces exerted by anticipated tsunamis and accompanying debris field; a buoyant inflatable survival life raft removably attached near a top portion of the vertical support column and capable of floating free from the vertical support column, and thereby protecting the occupants in the event of failure or overtopping of the support column; and adornments and coloring to allow the vertical support column and survival raft to blend with their surroundings by imitating trees indigenous to the area.

Abstract: A garment worn under a bridal gown in a manner similar to a petticoat having vertical strips of elastic to retract the garment under the gown for photographs. The elasticized hem of the garment can be pulled from under the bottom of the gown to allow the wearer to carry the gown and protect it from being soiled. The garment is provided with a tight fitting waistband that secures around the wearer's waist. A skirt of the garment is somewhat circular with the front somewhat shorter in length than the back. Loops are provided near the hem as a means for holding the hem of the garment when carrying the gown within the garment. An elastic band from the garment's hem can be pulled from the casing as shoulder straps for carrying the gown hands-free.
