Method and device for producing electromagnetic fields that influence the nervous system of insects
View Patent ↗The invention relates to a method and to a device for repelling insects by means of a two-channel pulse pattern transmitter ( 1 ), which, by means of the integrated antennas ( 34 a, 34 b ), emits two electromagnetic waves ( 35 a, 36 a ) phase-shifted against each other by 180 degrees and modulated and pulsed with the pulse patterns ( 24, 23 ) and produces two electromagnetic fields ( 35 b, 36 b ), which act on insects ( 45 ) located in the radiation range ( 76 ) in such a way that the neurons ( 50, 53 ) located in the supraesophageal and subesophageal ganglia ( 48, 51 ) and the sensory neurons ( 65 ), the motor neurons ( 66 ), and the interneurons that exist in the central and peripheral nervous system ( 63, 64 ) of bloodsucking insects ( 45 ) are influenced in such a way that the signals and reflexes produced by the neurons trigger abnormal behaviors that put the insects into an inactive state such that bloodsucking insects cannot penetrate the skin of humans and thus cannot suck blood.
1. A device for repelling bloodsucking insects with a two-channel pulse pattern transmitter which comprises a microprocessor and two transmitters and, via integrated antennas, renders electromagnetic waves emittable, wherein the electromagnetic fields generated influence neurons in the supraesophageal and suboesophageal ganglions, and neurons in the central and peripheral nervous system of bloodsucking insects in order to put them into an inactive state in which they do not penetrate the human skin and thus do not suck the blood, wherein the two-channel pulse pattern transmitter also comprises a modulator and a pulse pattern converter, wherein a pulse pattern generated by the microprocessor can be provided for inputs of the pulse pattern converter by the modulator at a first output as a positively modulated and at a second output as a negatively modulated pulse pattern, and the pulse pattern converter makes it possible to deliver the positively modulated and the negatively modulated pulse patterns to the transmitters in a phase-shifted manner.
2. The device according to claim 1 , wherein the two-channel pulse pattern transmitter takes the form of a compact, autonomous module.
3. The device according to claim 1 , wherein a coil is connected to a driver which coil can be controlled synchronously with the pulse pattern such that a voltage peak is generated which can be delivered to an FET via the input of the pulse pattern converter, such that the two pulse patterns can additionally be overlaid with a spike pulse.
4. The device according to claim 1 , wherein the modulator is expanded with two NAND gates in order to overlay the pulse patterns which are applied to the outputs with a high frequency signal, in order to generate at the outputs of the pulse pattern converter two carrier signals which are forwarded to the antenna terminals.
5. The device according to claim 1 , wherein the two-channel pulse pattern transmitter is integrated in a mobile system, a wristwatch, a wristband or a pendant.
6. The device according to claims 1 , wherein the two-channel pulse pattern transmitter is integrated in a mains-operated or a battery-operated system or into a system which has a power supply which is supplied by solar cells or fuel cells.
7. The device according to claim 1 , wherein the two-channel pulse pattern transmitter is integrated in an adhesive plaster as a compact, autonomous module.
8. The device according to claim 1 , wherein the two-channel pulse pattern transmitter includes two additional power amplifiers, which can be connected in series to the transmitters, in order to expand the radiation range.
9. A method for repelling bloodsucking insects with a two-channel pulse pattern transmitter which comprises a microprocessor and two transmitters and which, via integrated antennas, emits electromagnetic waves, wherein the generated electromagnetic fields influence neurons in the supraesophageal and suboesophageal ganglions and neurons in the central and peripheral nervous system of bloodsucking insects, in order to put them into an inactive state in which they do not penetrate the human skin and thus do not suck the blood, wherein the two-channel pulse pattern transmitter also comprises a modulator and a pulse pattern converter, a pulse pattern generated by the microprocessor is provided for inputs of the pulse pattern converter by the modulator at a first output as a positively modulated and at a second output as a negatively modulated pulse pattern, and the pulse pattern converter delivers the positively modulated and the negatively modulated pulse patterns to the transmitters in a phase-shifted manner.
