DESC:FIELD OF THE INVENTION
The present invention generally relates to field of repelling electronic device. In its particular, the present invention relates to a non-sweep ultrasonic wave device for pests and vermin repellent and method of operation thereof.

BACKGROUND OF THE INVENTION
There are many known types of pests and vermin like mosquitoes, insects, rats, cockroaches, lizards, snakes which annoy, pester and/or adversely affect mankind. Noxious pests such as rats or mice have long caused havoc in many places because of the harm such pests cause to property and life. More importantly, these pests are disease carriers and an unhealthy environment is created if such pests and vermin are permitted to occupy the same area as humans. Many types of devices, processes, chemicals and the like have been used in the past in order to exterminate and/or repel such pests.

One problem, generally found in extermination of pests and vermin is the use of toxic chemicals or similar substances. These materials are considered, toxic not only to the undesired pests or vermin but also to mankind, domestic animals, pets and the like. Consequently, these types of products must be used with extreme caution. Moreover, these products are precluded from use in some areas. For example, it is highly undesirable to use these kinds of products around food and the like. Also, use of these materials is undesirable in that the pest can ingest or absorb the material and carry it away. Thus, the pest can die in an inaccessible location causing the problem associated therewith in terms of attracting other pests or vermin and/or creating an unpleasant odor and infectious situation.

Other mechanical or electrical devices can be used such as applying force to physically eradicate or exterminate the pest. In other cases, the pest can be "zapped" by electronic means. As a result, the devices and related methods have difficulty that the unwanted pests and vermin is still exterminated on the premises which are to be controlled resulting in collateral undesirable consequences.

Further, many electronic pest repellent devices are also in vogue in market. However, these devices are also have certain limitations not useful in case of small pests due to various reasons such as adaptability, range, lone of site operation, etc.
To overcome the traditional electronic pest repellent emissions for small pests, electronic pest repellents with an ultrasound oscillator have also been used. Ultrasonic oscillator device relates to the generation of ultrasonic signals to be applied in the vicinity of pests, such as rodents and insects for the purpose of disrupting and irritating their ultrasonic receptors to the extent that they are repelled and seek to escape from the area in which the ultrasound is functioning. The ultrasound produces a stress on the antennae of the pests and repels them away.

Many devices have been disclosed in the prior art that relate to pest deterrent and ultrasonic signal generating devices. These include devices that have been patented and published in patent application publications. The following is a list of devices deemed most relevant to the present disclosure, which are herein described for the purposes of highlighting and differentiating the unique aspects of the present invention, and further highlighting the drawbacks existing in the prior art.

For instance, US4562561 discloses an electrical apparatus for repelling animal and insect pests using an ultrasonic signal that is pulsed or swept across a frequency range, wherein the ultrasonic receptors of the pests are disrupted and the pests are driven away from the signal source. A first, second and third signal are disclosed, along with a means for modulating the selected signal. The first signal includes a fundamental frequency of 22 kHz, the second signal having a pair of fundamental frequencies of approximately 22 and 35 kHz, and the third signal having a plurality of fundamental frequencies in the range of 18 kHz to 33 kHz. A means of sweeping through the fundamental frequencies is built into the circuit, while an ultrasonic transducer outputs the signal from the circuit. The device said, while disclosing a signal generator as a means of deterring pests, fails to disclose many of the key features inherent in the present invention, including the construction of the overall assembly, along with the options provided by the present circuit board design that allow four separate tone frequencies and a means of establishing a consistent narrow or broad range frequency sweep during operation. The ability to produce non-sweep ultrasonic pulsed waves in parallel transmission is not set out in the said patent.

US4999818 discloses a circuit for producing ultrasonic signals for repelling pests and vermin. The device comprises a transducer for producing ultrasonic signals, an audio amplifier, and an oscillator having at least a first and second multivibrator means. The oscillator includes a variable resistance network for adjusting the frequency thereof using an operable switch to choose a particular frequency. The transducer is preferably an acoustic speaker with a frequency range between 22 kHz and 50 kHz. The device offers a variable resistance network as a means of choosing the output signal. The ability to produce multi-source of oscillator which is use for interfering transducers and frequency range between 25 KHz to 125 KHz. The power supply of the pest repellent device of the present invention is in range of 12 Volts and 1Ampere which runs on the battery.

US7324408 discloses another pest repelling device installed within a vehicle, wherein the device is adapted to deter rodents and insects from entering and nesting within the engine compartment of a motor vehicle. The device comprises a control unit and a plurality of transducers adapted to connect to the control unit to provide a random sweep between 1 millisecond and 1 second bursts between a lower frequency of 20 kHz and an upper frequency of 45 kHz. The device is one that is adapted to be utilized in conjunction with a motor vehicle and be housed within the engine bay compartment, which can be prone to bird and rodent nests over time, and in particular if the vehicle is left parked outdoors for extended periods. The construction and intent of the device diverges from that of the present invention, which is designed for a large scope of application that include indoor use in buildings with human or animal occupation, ware houses, kitchens, for greenhouses and outdoor use, and includes a different circuit design and application of ultrasonic sound for pest deterrence. The ability to generates ultrasonic signals in the vicinity of pests, for the purpose of disrupting and irritating their ultrasonic receptors to the extent that they are repelled and seek to escape from the area in which the ultrasound is functioning and formation of wave cloud.

US6166996 discloses an ultrasonic broadband frequency transducer for pest repulsion, wherein the device comprises a variable frequency generator, at least one ultrasonic frequency amplifier, and a transponder unit comprising at least two transducers. The device is adapted to address the directional and attenuation problems with existing pest repulsion transducers, wherein most existing devices utilize a single frequency transducer that is centered about a center frequency and whose response curve sharply drops off moving away from this frequency. In comparison the present invention provides a novel non-sweep ultrasonic pest repeller for producing non-sweep ultrasonic pulsed waves in parallel transmission.

However, the elements and functions of the present invention differ significantly in design elements and in intent from the Grissom device. It will be appreciated that standard techniques for controlling direction, intensity and dispersion of sound may be utilized with this device to obtain the maximum protection with the power output available from a standard unit, and that by use of amplification, the protected area may be greatly increased and other directivity patterns provided.

Most pests are typically sensitive to a specific spectrum of frequency range called the ultrasound frequency. Generally, pests are repelled by using sound frequencies in the ultrasonic range above 20 KHz.

There is no completely adequate device available in prior art to repel pests because all pests, all pests of same species, are not necessarily sensitive to a particular signal of frequencies being transmitted.

Some pest repellers are constructed to produce a steady ultrasonic frequency. Since pest apparently builds up a tolerance to such steady frequencies, they are a failure from the existing device.

There are a number of problems associated with the existing electronic pest repellents which use ultrasonic-signal. Further, in case of any obstacle in the path, these signals get diverted or reflected and are not effective for large and different type of pest population. The exiting
repellants are ineffective against pests and vermin that hide in small cracks, slits, gaps and
holes as the ultrasonic waves are unable to travel effectively through these.

In order to overcome the drawbacks of the prior art, the invention provides a novel non-sweep ultrasonic device for pest repellent with parallel transmission of ultrasonic signal which is safe, reliable and effective in case of any obstacle in the path and to repel different types of pests and vermin.

(iii) Wherein the ultrasonic waves are capable of diffraction on encountering obstacles or slit.

The non-sweep ultrasonic wave pest repellent circuit may comprises a power supply of +12volts DC which is required for the proper functioning of IC(IC1-IC4).IC1 which is IC555 baised to work in astable mode in which it generate a square pulse of particular frequency, depending on the value of resistance (R1=470Kohm,R2=470Kohm)and capacitor (C1) the output of this IC (pin3) is used as clock pulse for IC2 (IC4017) which is decoder IC which count the number of pulse generated by the IC555. As the pulse arrives the output of this IC goes to logic 1’for example-
Pin 2 of this IC goes high when the IC555 generates the second pulse.

The output of this IC is connected to IC 3(IC555) via diode (D1-D10) and resistor (R4-R13) of different values as shown figure.1.

Here complementary transistors (NPN and PNP) may be used to obtain a full cycle output across a load using half cycles of operation from each transistor. A single input was applied to the base of both transistors.

The transistors, being of opposite types, conduct on opposite half cycles of the input. The NPN transistor was biased into conduction by the positive half cycle of the signal, with the resulting positive half cycle across the load. During the negative half cycle of the signal the PNP transistor may be equally biased into conduction giving also a negative output. During a complete cycle of the input, a complete cycle of the output signal may be developed across the load .The load was driven as the output of an emitter follower so that the load resistance is matched by the low output resistance of the driving source and this buffers the signal The symmetrical outputs from the NAND gate amplified in push-pull mode by transistors T3-T4 to drive the four high frequency piezo tweeters. When the quartz plate of the transducer subjected to an alternating electric field, the reverse piezoelectric effect causes it to expand and contract at the field frequency. If this field frequency is made to coincide with the natural elastic frequency of the crystal, the plate resonates. This physical displacement propagates sound waves.
