Patent number: 12042267Abstract: According to various embodiments, systems and methods for determining carbon dioxide detection in arthropods. An embodiment may include determining at least one resonant frequency of an arthropod sensory organ and an absorption spectrum of at least one odorant. A frequency filter may be applied to the absorption spectrum to eliminate frequencies below a given intensity value. Of the frequencies remaining from the absorption spectrum, those frequencies corresponding to relative peaks in absorption intensity may be selected. An olfactory chord including a group of the selected frequencies corresponding to the relative peaks in absorption intensity with at least one specific frequency that matches the at least one resonant frequency of the arthropod sensory organ. Additionally, at least one radiation source may be configured to emit electromagnetic radiation corresponding to the olfactory chord.Type: GrantFiled: September 6, 2019Date of Patent: July 23, 2024Assignee: TECHNOLOGY SG, L.P.Inventor: Thomas M.

Patent number: 10226035Abstract: An insect decoy is provided that includes a vapor-isolated vessel, a chemical compound disposed within the vapor-isolated vessel, and an excitation energy source. The chemical compound may have one or more absorption bands at a set of absorption wavelengths and have one or more emission bands at a set of emission wavelengths. The excitation energy source may be configured to produce electromagnetic radiation at the absorption wavelengths so as to fluoresce the chemical compound and release photons at the emission wavelengths. The vapor-isolated vessel may be configured with at least one infrared transmissive window that is substantially transparent to the released photons at the emission wavelengths of the chemical compound.Type: GrantFiled: November 2, 2015Date of Patent: March 12, 2019Assignee: Technology SG, L.P.Inventors: Eric L. Canfield, Thomas M. Dykstra, Scott J. Soma, Robert E. Rasmussen, Robert P. Alston

Patent number: 9775334Abstract: A system and method are provided to control the amplification of natural frequencies emanating from molecules, specifically insect sex pheromones. The pheromone molecules are deposited in a resonant cavity that allows the generation of coherent and/or semi-coherent radiation. The molecular emissions are amplified in the resonant cavity and allowed to escape through a small circular opening on top of the resonant cavity. The molecules and/or their emissions dissipate into the surroundings to attract insects towards the cavity. When the insect enters the resonant cavity, a trap door prevents the insect from exiting. The molecular emissions are produced by passive diffusion and passive amplification because no pumping radiation source is required. However pumping radiation can be integrated to assist the passive amplification or serve as a second attractant.Type: GrantFiled: October 31, 2014Date of Patent: October 3, 2017Assignee: TECHNOLOGY S.G., LPInventor: Thomas M. Dykstra
