Abstract
The invention relates to a pulsed infrared blinker that is used in the identification of friend or foe, creates a radiant effect in the thermal camera from the heat difference and allows different encoding processes at different heating-cooling frequencies.
Description
LIGHT
Technical Field
The present invention relates to pulsed infrared blinker that enables identification of friend or foe.
The invention particularly relates to pulsed infrared blinker that allows different coding operations to be performed by heating and cooling the thermoelectric cooler by energizing it with a certain frequency.
State of the Art
The Identification Friend or Foe (IFF) system is produced for military purposes and is used for radio broadcasting systems. The Identification Friend or Foe systems (IFF), which enable fast and accurate identification of friendly platforms in the battlefield by question and answer methods, are of vital importance for military operations.
In the state of the art, products that create awareness by creating a temperature difference (pocket stove, filament, aluminum foil) without a certain encoding opportunity can easily be imitated by the enemy. This situation is generally achieved with a fixed password in systems that can be encoded. Fixed encoding causes difficulties in terms of high cost and product uselessness.
In another state of the art, prism systems operating only at a certain wavelength by using laser perform imaging only for the specified band. A camera operating on that band is required so as to identify friend or foes in the system because the imaging will be carried out in a certain band range.
As a result of the research made in the state of the art, document No US20070236384A1 is encountered. The application relates to the IFF system equipped with a light receiver and light source emitting an encrypted infrared (IR) signal detectable by the shutter button. Flowever, in the application, a system that can perform different encoding processes by heating the thermoelectric cooler is not mentioned. Therefore, the technical problem of being imitated by the enemy cannot be eliminated because different encoding processes cannot be performed in the application.
As a result due to the abovementioned disadvantages and the insufficiency of the current solutions regarding the subject matter, a development is required to be made in the relevant technical field.
Aim of the Invention
The invention aims to solve the abovementioned disadvantages by being inspired from the current conditions.
The main aim of the invention is to enable different encoding processes to be performed by heating and cooling the thermoelectric cooler with a specific frequency, thus to avoid from its being imitated by the enemy.
The aim of the invention is to provide blinkers of small size and low cost.
In order to fulfill the abovementioned aims, the present invention is a pulsed infrared blinker that is used in the identification of friend or foe, creates a radiant effect in the thermal camera from the heat difference and allows different encoding processes at different heating-cooling frequencies, comprising the following;
• at least one bifacial thermoelectric cooler,
• at least one wave generator, which can be adjusted at different frequencies, heats and cools the thermoelectric cooler at different frequencies by connecting the thermoelectric cooler to give current in different directions to create a heat difference in the thermoelectric cooler
• at least one battery that provides the required voltage to said thermoelectric cooler.
The structural and characteristic features of the present invention will be understood clearly by the following drawings and the detailed description made with reference to these drawings and therefore the evaluation shall be made by taking these figures and the detailed description into consideration.

Detailed Description of the Invention
In this detailed description, the preferred embodiments of the inventive pulsed infrared blinker are described by means of examples only for clarifying the subject matter.
In Figure 1 , the representative view of the inventive pulsed infrared blinker is shown. Accordingly said blinker, so as to allow different encoding processes at different heating-cooling frequencies to be used in identification of friend or foe, comprises at least one thermoelectric cooler (2), a battery (3) providing the required voltage to the said thermoelectric cooler (2), and an adjustable wave generator (1).
The thermoelectric cooler (2) is a bifacial semiconductor that ensures heating, cooling and heat control with the passage of the direct current. When direct current is applied to the thermoelectric cooler (2);
• Temperature difference occurs between the surfaces of the thermoelectric cooler (2).
• Heating and cooling can be obtained in the thermoelectric cooler (2), depending on the direction of the current. It is possible to change the direction of the heat by reversing the direction of the applied current and changing the amount of heat transfer by changing the intensity of the current.
The battery (2) supplies the required voltage of the thermoelectric cooler (2). In a preferred embodiment of the invention, the battery (2) can be combined with the thermoelectric cooler (2) or it can be attached to a different section rather than the thermoelectric cooler (2).
The wave generator (1) generates an adjustable square wave. The wave generator (1) supplies a square wave voltage at the specified frequency to the thermoelectric cooler (2). The wave generator (1) is connected in a manner such that it gives current in different directions to the surfaces of the thermoelectric cooler (2). Therefore, temperature difference occurs in the thermoelectric cooler (2) depending on the opposite current directions. A radiant feeling is ensured in the thermal camera by heating and cooling the thermoelectric cooler (2) by operating the same at a certain frequency according to the difference in temperature. Different frequency values can be supplied from the wave generator (1) to the thermoelectric cooler (2). Therefore, the thermoelectric cooler (2) causes different radiation values to be detected from the thermal camera with variable frequency values. Therefore, the imitation of the system by the enemy is eliminated by making different encoding processes at different heating and cooling frequencies.
In a preferred embodiment of the invention, the thermoelectric cooler (2) operates at 12V voltage.
In a preferred embodiment of the invention, the thermoelectric cooler (2), wave generator (1) and battery (2) can be brought together and placed on a military helmet, uniform etc. The present invention provides opportunity to offer alternatives with thermoelectric coolers in different numbers and different heating-cooling combinations.
