Abstract: A method and device for the detection of vapors of cocaine and associated compounds are disclosed. The method involves sampling a volume of air suspected of containing cocaine vapors, passing this air through a filtration system that removes any particulate matter and binds vapors of cocaine and associated compounds, if present, for further analysis. A preferred associated compound-vapor is that of ecgonidine methyl ester (EDME), and a marker for the presence of cocaine. The device is comprised of a sampling, filtration and vacuum port components and can be easily attached to a container, and suction source, for the sampling of air.

Abstract: A pool heater to be installed on a commercially available residential heat pump in order to add swimming pool heating to the basic functions of the heat pump, i.e. heating and cooling of a dwelling. This "add-on a heat pump" pool heater comprises a refrigerant-to-water heat exchanger with a water flow control and associated piping, a water temperature control, a flow detecting device and a specialized control logic which is integrated to the heat pump control. The heat exchanger is connected on the refrigerant side to the outlet of the compressor of the heat pump circuit and to the inlet of the reversing valve. On the water side, the heat exchange is connected on a diversion loop of the pool water filtration system to allow water to be heated by the refrigerant exiting the compressor. The integrated control conserves all the basic modes of the heat pump, i.e.
