Abstract: An attractant for an insect trap functions by creating an attractive smell or other olfactory sensation, or an antennal response which elicits a behavioral response for a flying insect. In the case of the housefly (musca domestica), preferred attractant ingredients are tremethylamine, butyric acid, Z-9-tricosene (muscalure), and egg powder. Highly volatile attractant components are dispensed separately, and all air-borne attractants are mixed and distributed together to enhance the synergistic effects between them. The present invention is the first explicit report of the synergy between chemical attractants (e.g. trimethylamine and butyric acid) and food attractants, such as egg powder. If the attractants of the present invention are packaged in a cartridge, then precise amounts of the discreet chemical attractants can be metered out for optimum attraction of insects.

Abstract: An attractant based insect trap has a fan placed close to an insect attractant. The insect attractant creates an attractive smell, taste or other olfactory sensation that elicits an attractive response in the insect. The flying insect moves toward the fan mechanism against the flow of attractant-laden air, in order to reach the source of the attractant. The flying insect enters the trap, toward the source of the smell, which is the fan. The entrance to the trap leads into a bag, into which the insect moves to find the source of the attractant, and is trapped within the bag. The user may easily remove the bag from the interior of the trap, and dispose of the bag in a refuse receptacle. A new bag is then placed in the interior of the insect trap, and the trap is ready to trap more insects.

Abstract: An omnidirectional lightning ranging, identification and protection system having circuits that produce no false alarms or failures to alarm, responsive to cloud to ground and cloud discharges, capable of differentiating between cloud to ground and cloud discharges insensitive to background noise, autonomous with respect to power and communications conductors for operating reliably in the presence of nearby lightning discharges, requiring no field calibration, that provides local and remote lightning rate and range data, and that provides mechanisms for automatically signalling and disconnecting electrical equipment for the purpose of lightning protection. The system has circuits that are responsive to the electric field changes produced by lightning discharges in the frequency range between 2 khz and about 200 khz and to time coincident optical radiation in the 6000 to 9000 angstroms wavelength range.
