TR TR DESCRIPTION MAGNETIC BASED METER THAT PROVIDES ANGLE OR LINEAR MOTION MEASUREMENT IN ROTARY AXIS SYSTEMS Technical Field The invention is the change that it creates on the sensor with the direct angled mounting of the flexible strip magnet. Magnetic-based angle, which allows angle measurement in rotary axis systems or distance measurement in linear movements by providing magnetic field angle measurement. State of the Art Magnetic sensors convert magnetically encoded information into electrical signals to be processed by electronic circuits. Magnetic sensors are solid-state devices that are becoming increasingly popular because they can be used in many different applications such as position, speed or directional motion. They are also a popular sensor choice for electronics designers due to their non-contact, wear-free operation, low maintenance requirements, robust design and the fact that the sealed hall effect devices are immune to vibration, dust and water. One of the main uses of magnetic sensors is in automotive systems for sensing position, distance and speed. For example, the angular position of the crankshaft for the firing angle of spark plugs, the position of car seats and seat belts for airbag control, or wheel speed detection for anti-lock braking system (ABS), etc. can be used in systems. Magnetic sensors are designed to respond to a wide range of positive and negative magnetic fields in a variety of different applications. A type of magnet sensor whose output signal is a function of the magnetic field intensity around it is called a Hall Effect Sensor. Magnetic sensors can be applied in many systems due to their ergonomic structure to provide angle measurement in rotary axis systems. An example of this type of applications is reading the joint angle of knee joints with microprocessors. Microprocessor knee prostheses are designed for safe and comfortable walking. These prostheses are more useful than conventional systems and have become the first choice of amputee patients today. Microprocessor knee prostheses estimate gait phases with the help of various sensors. In this way, they use their propulsion system to support walking, according to the phase they estimate. The knee joint angle sensor plays an important role in gait phase estimation. When existing product solutions such as incremental encoder, absolute encoder and linear potentiometer for angle reading are examined, installation problems and high costs emerge as disadvantages. Patent application number CN218943610U mentions an artificial knee joint. It is understood from the specification set of the patent application numbered CN218943610U that a slot mechanism is described for sliding the sensor in a way that maintains its position against the magnet. It is understood that the patent application numbered KRlOl889656B1 talks about an artificial femoral limb with sensing tools. Aforementioned. sensor of the structure. It is understood that it has a detection tool that can be operated by moving it closer or further away from the Gauss field. The systems used to detect angles for the joints, which are included in the standard state of the art and whose details are presented above, require the creation of mechanically complex systems. As systems become more complex, angle detection mechanisms can take up much more space. Application knee joint Etc. If it is installed on systems, the total size of the detection mechanism and the area it covers may pose a significant handicap in terms of system design and application ergonomics. Again, making the detection mechanism to be used more complex will increase production costs as it will lead to manufacturing difficulties. Again, the structure becomes more complex. and may cause operating costs to increase. Problems the Invention Aims to Solve The purpose of the invention is to use a magnetic-based angle or travel distance meter that allows angle measurement in rotary axis systems by providing angle measurement of the changing magnetic field created on the sensor by direct angled mounting of the flexible strip magnet, or measurement of movement distance by angled mounting of the magnet in linear motion. is to be created. The protractor of the invention is operated by measuring the changing magnetic field created by at least one flexible strip magnet on at least one sensor. Thanks to the simple structure created, it has become possible to create minimal systems for angle measurement in environments where space and size problems occur. For example, when the structure subject to the invention is made in environments where the application area is limited, such as the knee joint, the total structure of the knee prosthesis increases significantly, as knee prostheses with an important microprocessor must also contain different electronic controllers. Again, the necessity of fitting different electronic components into the prosthesis structure also causes a decrease in the area available for the protractor used. Increasing this area used for protractor systems will cause the total structure of the knee prosthesis to increase significantly and will prevent the ergonomic design of the knee prosthesis. However, the use of the structurally much smaller protractor that is the subject of the invention can provide a significant design advantage in terms of designing ergonomic knee prostheses. Again, thanks to the simple structure of the protractor of the invention, application and maintenance costs can be significantly reduced. Explanation of Figures Figure 1.

Description of the Invention. The invention provides angle tracking of angular motion mechanical systems or linear motion mechanical systems in the electronic environment. of linear movements. of follow-up. It is related to the magnetic-based protractor or travel distance meter that enables this to be done. In its most basic form, the said protractor contains at least one magnetic element (1) that is flexible and in strip form, and at least one sensor (3) associated with the said magnetic element (1) that can detect magnetic field changes in case of angular movement. According to one of the preferred embodiments of the invention, the magnetic element (l) is in magnet form. Within this configuration, the magnet can be placed in a shell and used. According to Figure 1, the said shell is shown as body (2). According to Figure 1, the magnetic element (l) is formed in the form of a flexible strip and is associated with the mechanical system at an angle. According to Figure 1, the magnetic element (1) is placed within the body (2) in whose structure at least one placement channel (4) is created. More specifically, the magnetic element (1) is placed at an angle into the placement channel (4) created within the body (2). Within this application, the placement channel (4) and/or the body. (2) cross-section. most. At least one part of it is formed in a circular form, and the magnetic element (1) is designed in the form of a spring in accordance with this structure. Within this configuration, the magnetic element (1), which is in the form of a strip and flexible natural magnet, can be easily placed into a body (2) and used. In order to operate the protractor of the invention, it will be sufficient to magnetically associate the sensor (3) and the magnetic element (l). According to Figure 1, the sensor (3) is positioned outside the circular body (2). Different applications of the invention can also be operated by positioning the sensor (3) inside the body (2). The circular movement of the assembly provided in this configuration creates a variable magnetic field on the sensor (3). The sensor (3) that measures the changing magnetic field can make precise angular measurements. The sensor (3) described within the invention can be any magnetic field sensor. Hall effect and magnetic field sensors can be given as examples. If the inclined shell is made flat, position measurement of linear moving systems can be made. An example of linear motion systems is linear actuators. In one of the preferred applications of the invention, the mentioned protractor can also be used to electronically monitor the angle of microprocessor-controlled knee prostheses. As explained above, the use and assembly of the protractor, which is created by operating a few simple components together, can provide a very simple solution. In this way, an advantageous structure can be foreseen in terms of both production and operating costs. It is possible to use incremental and absolute encoder models, which have the same usage area, in some mechanical designs in terms of assembly relations. It is not. Applications such as microprocessor knee prosthesis design are an important example of this situation. Since the protractor of the invention has a very simple, compact and monolithic structure, it can be easily applied in many applications where other encoder models cannot be used. Sensor output data using the angle sensor (3) (rotation angle/linear displacement) is included in the table presented in Figure 3. In order to create the protractor or linear movement distance of the invention, sensors (3) of different structures that can measure magnetic field can be used alone or together. At this point, it is possible to use any sensor (3) that can accurately detect the magnetic field created by the magnetic element (1). Figure 4 shows the magnetic element (1), which is mounted linearly by specially polarizing it, instead of placing an angled strip magnetic element directly into the body (2). Within this application, the magnetic element, which is created in strip form and mounted linearly on the body, can be placed in the body at an angle relative to the sensor (3) or at an angle relative to the sensor. Thanks to this positioning, a solution can be achieved by changing the position or polarization of the linearly structured magnetic element (l) within the body relative to the sensor (3), without the need to configure the magnetic element (l) as an angled strip. Figure 4 shows applications for left and right polarization of the magnetic element (l) in order to create special polarization situations. Figure 5 shows the magnetic element (l) polarized front and back instead of left and right. By using this application, it will be possible to create a changing magnetic field on the magnetic sensor (3). Different structures can be made by changing the Gauss value of the magnetic element (l) used in the invention. It is possible to create . For example, when the Gauss value of the magnetic element (l) is increased, it is possible to increase the mechanical gap between the sensor and the magnet. Figure 6 shows an example of the application of the protractor for electronic angle tracking of microprocessor-controlled knee prostheses. Within this application, the protractor is associated with the knee joint rotation axis (5), which is the axis on which the joint angle sensor should read. Within this configuration, the knee joint can be connected to the foot direction prosthesis components through the foot direction prosthesis connection point (6) and to the socket via the socket's prosthesis connection point (8). Again, within this application, the knee joint is equipped with the connection point (7) of the drive system to the knee joint. TR TR
