Description

DESCRIPTION PORTABLE SIX-VARIOMETERS FOR SPORT AVIATION Technical Field In aircraft, altitude and ascent and descent rate information are among the most important flight data. This invention relates to an electronic device that transmits altitude, descent and ascent rate information to the pilot via visual and audio signals. Prior Art Document numbered US3964307A describes how to obtain ascent/descent rate data in aircraft with a mechanical device. The device mentioned in the patent consists of only mechanical components and it is not practical to apply it to today's aircraft with advanced electronic systems. Document numbered EP0024904A2 describes how to obtain ascent/descent rate data with an electronic device. The device mentioned in the patent consists of many analog electronic components, making the device functional only on relatively large air platforms such as civil or military aircraft or helicopters. The document numbered GB2254742A describes how to convert ascent/descent rate data into an audible warning tone with an electronic device. The device mentioned in the patent does not contain visual components, and it is considered to be an inadequate device since it only produces audio output. The document numbered JPH07134043A describes an electronic device for reporting altitude and altitude changes to the pilot. The device contains pressure and temperature sensors and allows the connection of an external wind sensor. The speaker and display used to report the data to the pilot are also described. The device also contains a series of keys for receiving user inputs. The SYSaAlti, SYSaGPS and SYS, Nav devices produced by Syride Instruments allow for audio and visual notifications to the pilot regarding altitude and altitude changes. The devices offer a simple interface for easy use. Purposes of the Invention The invention is an electronic device that accepts the methods identified above as the basis and eliminates the deficiencies in these methods with the most up-to-date digital electronic devices. The device is a portable electronic device that works with a rechargeable battery and visually and audibly informs the user about altitude (altimeter) and descent/ascent rate (variometer). For this reason, the device includes atmospheric pressure and temperature sensors, liquid crystal display, rechargeable battery and storage box. The invention brings together these components produced with up-to-date technology in a unique software and hardware configuration to define a low-cost device especially targeted for use in sport aviation activities.

Speaker Detailed Description of the Invention The invention is basically an electronic device comprising a central processing unit (1), a power supply (2), a pressure and temperature sensor (3), a user output interface (4) and a user input interface (5). The central processing unit (1) receives the electrical energy required for its operation from the power supply (2). The power supply (2) is a 3.7 V lithium-ion battery. When the lithium-ion battery (2) runs out of energy, it is charged by the central processing unit (1) which is fed via the microUSB charging socket (11). The LED indicator light (12) is on during charging and automatically turns off when charging is complete. The central processing unit (1) receives the relevant data electronically from the atmospheric pressure and temperature sensors (3). The central processing unit (1) mathematically calculates the altitude from the atmospheric pressure information with the microcontroller it contains. The central processing unit (1) also mathematically calculates the descent/ascent rate from consecutive atmospheric pressure information. The central processing unit (1) continuously measures the voltage of the power supply (2). The central processing unit (1) also measures the time elapsed since the device was energized. The central processing unit (1) sends the calculated and measured data to the user output interface (5). The user output interface (4) includes the visual element liquid crystal display (9) and the auditory element speaker (13) components. The altitude information, descent/ascent rate information, ambient temperature information, power supply voltage information and chronometer information displayed on the liquid crystal display (9) are updated twice per second. The central processing unit (1) sends an intermittent sound signal to the speaker (13) whose frequency increases linearly with the rise/fall ratio. In this way, the user can audibly understand whether the device is rising or falling without looking at it. The speaker (13) has three different sound levels. The device is turned on and off with the on-off switch (10). The on-off switch (10) is a mechanical slide switch. The purpose of the switch being on the side panel of the device is to prevent the device from being turned off in case of unintentional contact with the front panel during use. In addition, this type of switch has a lower failure rate due to lack of contact over time compared to membrane type switches. In this way, the reliability of the device's on/off operation has been increased in the long term. The operating configuration of the device is set with the "+" button (6), "MENU" button (7) and "-" button (8) on the device. These buttons constitute the user input interface (5). The plan LED lighting is turned on/off. In this way, the liquid crystal display (9) can be easily read in low light conditions. The unit is increased. The unit is decreased. It is turned off. In this way, the audible warning sent to the speaker (13) during altitude decreases can be turned on and off. The indicator is turned off together. In this way, the audible warning sent to the speaker (13) during altitude increases or decreases can be turned off. After this, when the "+" button (6) is pressed for less than 2 seconds, the descent sound indicator and the ascent sound indicator are turned on again together. Thus, the audible warning sent to the speaker (13) in case of altitude increase or decrease can be turned on again. and the altitude offset screen, which is increased and decreased with the "-" button (8), appears. This process may be necessary due to atmospheric pressure changes. Pressing the "MENU" button (7) for more than 2 seconds returns to the main information screen. After the previous step, pressing the "MENU" button (7) for less than 2 seconds brings up the variometer offset screen, where the descent/ascent rate threshold levels are increased and decreased with the "+" button (6) and "-" button (8). This process is related to the preference after which descent/ascent values the sound should be heard from the speaker (13). Pressing the "MENU" button (7) for more than 2 seconds returns to the main information screen. After the previous step, by holding down the "MENU" button (7) for less than 2 seconds, the contrast setting screen appears, where the contrast level of the liquid crystal display (9) is increased and decreased with the "+" button (6) and "-" button (8). This process is related to the readability preference of the liquid crystal display (9). By pressing the "MENU" button (7), the main information screen is returned. Application of the Invention to Industry The invention titled "Portable Six-Variometer for Sports Aviation", which is mentioned in detail above, can be produced, used and applied in any branch of the industry.
