The present invention relates to devices and equipment to repel monkeys from a garden or a home site. More specifically, it relates to monkey repellent dummy device using a langoor or Colobine monkey shaped dummy equipped with electronic circuit that repels the monkeys.
BACKGROUND OF THE INVENTION Monkeys are great menace these days in urban areas. A lot of efforts are being done to curb this menace by way of many repellent devices or systems. One of the earliest methods of monkey repellent apparatus is the traditional scarecrow. However, as the monkeys have become accustomed to the presence of the scare crow repellent apparatus, it became increasingly less effective at performing its appointed function.
Another traditional way to repel the monkeys is to hire a langoor, also called Colobine monkey. As these two species are rivals and the langoor or Colobine monkey is stronger than the monkey therefore monkey is afraid of langoor or Colobine monkey. In India, cruelty towards animals is banned by the government and so who-so-ever hires a langoor or Colobine monkey, he has to pay a lot of money as it is considered illegal. Moreover langoor or Colobine monkeys are not easily available and cannot be an immediate solution for the monkey menace.
Problems in existing systems:
i. Langoor or Colobine monkey as such cannot be hired as it is banned by the government.
ii. Other methods include use of repellent devices using ultrasonic waves, that are harmful to people.
iii. The existing devices are expensive and cannot be purchased by a common user.
Hence there is a need to provide a method or system for repelling the monkeys in urban areas, which is convenient, is highly efficient and does not pose a physical risk to wildlife, pets and human beings. Such system should be legally valid and should be cost effective so that people can afford it.
3
Prior art methods and systems for addressing these needs are either too expensive, inhumane, ineffective or a combination of all of these.
INNOVATIVE SOLUTION PROPOSED BY THE INVENTORS
The inventors have carefully studied the behaviour of common monkeys in urban areas. They concluded that the only way to scare these monkeys is to develop a dummy device which could repel monkeys without harming them physically.
Monkeys being intelligent enough, very easily detect that the device producing ultrasonic waves is merely an electronic gadget. So they become immune to these devices and do not respond. Moreover such devices are harmful for the humans who are in that zone.
So the only possibility of scaring away the monkeys is to develop a dummy of a Langoor or Colobine monkey of which monkeys are still afraid of. The dummy should have some features such as sound of a Langoor or Colobine monkey itself. This can create a scene for the monkeys that the Langoor or Colobine monkey is alive and thus producing sounds. The dummy of the present invention is equipped with sensor for detecting approaching animals and producing sound to scare approaching animals.

DESCRIPTION FIG 2:
The IC used in the amplifier is LA or LM 4440. LA4440 is a two channel 14 Pin audio power amplifier IC with inbuilt dual channels enables it for stereo and bridge amplifier applications. In dual mode, it gives 6 W per channel and in bridge mode 19 W output. IC LA 4440 is wired as a stereo amplifier to deliver a 19 W output on an 8 Ohm speaker. The IC has built in thermal, over voltage and short circuit protection. The IC also incorporates an audio muting function. It has good ripple rejection of 46 DB, small residual noise, built in over voltage and surge voltage protection etc. Ideal feature of the IC is its pin-to-pin protection. LA4440 is wired in Bridge Stereo configuration using both inputs and outputs.
*Key Features of amplifier  Built in two channels to use as Mono and Stereo  Dual mode 6W x 2 and Bridge mode 19W  46 dB Ripple rejection  18V Max. Power handling and 12V typical  Good channel separation and low distortion

 Built in Audio Muting function and Pin-to-Pin protection  Surge protection circuitry
 Minimum number of external parts required
 Small pop noise at the time of power supply ON/OFF
 Good starting balance
 Small residual noise
While using IC LA4440 several things needs to be taken into consideration:
Maximum ratings -If the IC is used in the vicinity of the maximum ratings, even a slight variation in conditions may cause the maximum ratings to be exceeded, thereby leading to breakdown. An ample margin of variation for supply voltage, etc. should be allowed and the IC should be used in the range where the maximum ratings are not exceeded.
Printed Circuit Board -No feedback loop should be made between input and output during making the board.
Oscillation preventing capacitor -Normally, a polyester film capacitor is used for 0.1mF + 4.7W. The capacitance value can be reduced to 0.047mF depending on the stability of the board.

In a preferred embodiment of the present invention, whenever monkeys enter the premises, instead of shooing them off manually or with the help of a stick which is a cumbersome method, the monkey repellent dummy device is placed in the premises and is switched on. It starts generating a sound very similar to that of a langoor or Colobine monkey thereby creating a visual simulation of a live langoor or Colobine monkey sitting in the premises. The monkey due to its natural tendency of getting scared on site of a langoor or Colobine monkey making noise gets repelled and leaves the premises quickly. The device is eco- friendly as it is not using any ultrasonic to detect or repel monkeys rather it is simply a sound generator in the shape of a dummy of a langoor or Colobine monkey, so it is no way harmful for the surrounding people.

The monkey repellent dummy device of present invention comprises of a solar panel charged power supply that can either be AC or DC. A 12 Volt DC power supply is used that is able to deliver at least 3 ampere current. The power supply is connected to the sound emitting device that generates the particular sound already pre fed by the applicant. The sound emitting device via the amplifier circuit enables the device to modulate certain sound frequencies and select the sound frequencies that is required. The speakers produce the output in the form of sound waves that helps to repel monkeys. Usually a 4 Ohm speaker is used as load and 8 Ohm can also be used to serve the purpose.
Novelty- The novelty of the present invention lies in developing a monkey repellent dummy device that is eco- friendly, does not use any ultrasonic waves to detect or repel the monkeys. The device is cheap and easy to manufacture and is environment friendly.
Inventive Step-The inventors have achieved the novelty by using an electronic circuit embedded in the shape of dummy of a langoor or Colobine monkey, so it is no way harmful for the surrounding people. The device employs the use of amplifier that generates a sound very similar to that of a langoor or Colobine monkey thereby creating a visual simulation of a live langoor or Colobine monkey sitting in the premises. The monkey due to its natural tendency of getting scared on site of a langoor or Colobine monkey making noise, gets repelled and leaves the premises quickly.
