Abstract: Apparatus for training a subject dog to perform target odor detecting operations within a completely confined compartment, which comprises a partial compartment having at least three angularly different surfaces to define an interior. The surfaces are sufficiently long to provide a subject dog located within the interior with a sensation of being at least partially confined. An air inlet is defined by a configuration of the partial compartment, by which odor laden air is introducible into the interior and is detectable by the nose of the subject dog. A dog interfaceable member is operatively connected to the partial compartment and activatable upon detection of a predetermined target odor.

Abstract: A biological sensor based system for detecting odors, which comprises (a) a compartment for completely or partially secluding and enclosing a biological sensor located therewithin that is configured to enable the biological sensor to perform normal animal motions as well as an odor detection operation; (b) an air inlet in the compartment through which odor laden flows into an interior of the compartment; (c) an air outlet through which the odor laden air is dischargeable from the compartment; (d) an animal depressible button which is movably connected to a wall of the compartment and is depressible by the biological sensor upon detection that the introduced odor is a predetermined target odor; (e) a force sensor connected to the button for sensing the pressing parameters applied by the biological sensor onto the pushbutton; (f) an analysis unit for determining whether the pressing parameters are within an expected range for the biological sensor and for transmitting an alert signal to a law enforcement entity
