Specification

Description:FIELD OF THE INVENTION

[0001] The present invention relates to an adjustable drawing ruler holding device that is capable of providing a means to hold a drawing ruler as per dimension of the ruler over a sheet along with orienting the ruler parallel to upper surface of the ruler in order to draw lines over the sheet in appropriate manner.

BACKGROUND OF THE INVENTION

[0002] A drawing ruler is a tool used in drafting and drawing to create straight lines or to measure distances accurately. It typically consists of a flat, straight edge with markings for measurement along its length. Drawing rulers come in various materials such as wood, plastic, or metal, and they can have different units of measurement marked on them, such as inches, centimeters, or both. They are essential for precise and neat drawings in various fields, including architecture, engineering, graphic design, and art. Holding tools for the drawing rulers makes it easier for the user to focus on drawing or measuring.

[0003] Traditionally, various methods and tools are used to hold the drawing rulers. People use a heavy object, such as a paperweight or a block of wood, is placed at each end of the ruler to hold it steady on the drawing surface. Drawing board clamps and clips are also used to hold the ruler securely in place. While these traditional methods may offer some benefits, but they also pose several challenges and drawbacks. Traditional tools like paperweight do not provide sufficient stability which may led to inaccuracy in drawings due to ruler movement. Also setting up and adjusting traditional holding methods might be time-consuming and cumbersome.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0019] As used herein, the singular forms "a," "an," and "the" designate both the singular and the plural, unless expressly stated to designate the singular only.

[0020] The present invention relates to an adjustable drawing ruler holding device that is capable of holding a drawing ruler as per dimension of the ruler over a sheet along with orienting the ruler parallel to upper surface of the ruler in order to draw lines over the sheet in appropriate manner. Additionally, the proposed device also detects presence of the user's hand over the ruler while the user is drawing lines over the sheet to notify the user regarding the detected alignment/ position of hands.

[0021] Referring to Figure 1, an isometric view of an adjustable drawing ruler holding device is illustrated comprising a frame having a cuboidal body 1 configured with a pair of telescopic rods 2, each integrated with a suction unit 3, an artificial intelligence based imaging unit 4 mapped on the frame, a speaker 5 mapped on the frame, and multiple motorized clippers 6 attached with the rods 2.

[0022] The proposed device comprises of frame having a cuboidal body 1 developed to be held by a user for positioning the body 1 over a paper sheet. Herein, the body 1 is configured with a pair of telescopic rods 2, each integrated with a suction unit 3 for affixing the body 1 over a ruler present over the sheet. The rod is equipped with a pneumatic unit that is activated by a microcontroller to provide extension and retraction of the rod. The pneumatic unit comprises of an air compressor, air cylinder, air valves and piston. The air valve that allows entry or exit of the compressed air from the compressor. Furthermore, the valve opens and the compressed air enters inside the cylinder thereby increasing the air pressure of the cylinder. The piston is connected to the cylinder and due to the increase in the air pressure, the piston extends due to which bars extend to press the suction unit 3 with the body 1 in front of the air vent that aids to affix the body 1 over the ruler present over the sheet.

[0023] Further, an artificial intelligence-based imaging unit 4 is installed on the frame for detecting dimensions of the ruler. The imaging unit 4 comprises of a camera and processor that works in collaboration to detect the presence and angle of person(s) inside the enclosure installed with the air conditioner. The AI (artificial intelligence) protocols encrypted with the processor linked with the imagining module to enhance its functionality and capabilities. The AI protocols are used to process and analyses the images captured by the camera enabling it to perform various tasks beyond traditional image capturing. The AI analysis is performed locally on the camera itself and the real-time processing on the camera enables immediate responses and faster decision-making.

[0024] The camera, herein captures images of the surrounding with the help of specialized lenses designed to capture high-quality visuals. The captured data is now pre-processed via the processor to enhance its quality and prepare it for AI analysis. This pre-processing involves tasks such as noise reduction, image stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information present in the images.

[0025] The camera is capable of analysing the surrounding and providing real-time updates or alerts about the surrounding based on predefined rules or criteria. Herein, based on extraction of the data from the captured images to detect dimension of the ruler. Based on detecting the dimension of the ruler, the microcontroller actuates rods 2 to extend for positioning the rods 2 in contact with the upper surface of the ruler, followed by actuation of the suction unit 3 for securing the body 1 over the ruler.

[0026] An angle sensor integrated on the frame for detecting angle of inclination of the ruler with respect to the sheet. The angle sensor works based on the principle of detecting changes in magnetic fields or optical signals. By analyzing these changes, the angle sensor accurately determines the angle or position of the ruler with respect to the sheet being measured. This information is then further transmitted to the microcontroller in the form of digital signal to analyze and detect angle of inclination of the ruler with respect to the sheet. Based on detection, the microcontroller actuates the rods 2 to extend/retract for orienting the ruler parallel to the surface.

[0027] Further, a proximity sensor is installed on the frame and synced with the imaging unit 4 to detect presence of the user's hand over the ruler while the user is drawing lines over the sheet via the ruler. The proximity sensor employs both inductive and capacitive principles. It employs an oscillating electromagnetic field to induce currents in surrounding of the user causing the capacitance of the sensor to fluctuate. This difference is measured and utilized to identify the presence of the user's hand over the ruler relative to the sensor. Furthermore, the sensor calibrates the fluctuated capacitance to determine the presence of the user's hand over the ruler while the user is drawing lines over the sheet via the ruler

[0028] Upon detecting the presence of the user's hand over the ruler while the user is drawing lines over the sheet, the microcontroller activates a speaker 5 mapped on the frame to notify the user regarding the detected alignment/ position of hands. The speaker 5, herein includes a diaphragm, which is typically made of a lightweight and rigid material like paper, plastic, or metal. It is designed to vibrate and produce sound waves when electrical signals are fed to it. A voice coil (a tightly wound coil of wire) attached with the diaphragm of the speaker 5. The voice coil is suspended within a magnetic gap. When an electrical current flows through the coil, it interacts with the magnetic field produced by the magnet assembly, resulting in a force that moves the coil. The magnet assembly creates a magnetic field within the speaker 5. It consists of a permanent magnet and a metal structure, such as a pole piece or a magnet plate. The magnet assembly provides a fixed magnetic field through which the voice coil moves. The strength and configuration of the magnet assembly influence the performance and efficiency of the speaker 5.

[0029] The cone/diaphragm is connected to the speaker 5's frame via a suspension unit, which includes the surround and spider. When the electrical signal passes through the voice coil, it generates a magnetic field that interacts with the fixed magnetic field produced by the magnet assembly. As the electrical current varies, the magnetic field produced by the voice coil changes, resulting in the voice coil and attached cone/diaphragm moving back and forth. This movement creates pressure variations in the surrounding air, generating sound waves to generate the audible sound to notify the user regarding the detected alignment/ position of hands.

[0030] Moreover, a moisture sensor mapped on the rod to detect presence of moisture over the sheet. The moisture sensor works on the principle of measuring electrical conductivity or capacitance by using probes or electrodes that come in contact with the sheet, and the level of moisture affects the electrical properties of the moisture. By analyzing these changes, moisture sensor accurately determine the moisture level in the sheet. Based on detection, the microcontroller activates the speaker 5 to notify the user regarding the detected moisture present on the sheet.

[0031] Lastly, a battery (not shown in figure) is associated with the device to offer power to all electrical and electronic components necessary for their correct operation. The battery is linked to the microcontroller and provides (DC) Direct Current to the microcontroller. And then, based on the order of operations, the microcontroller sends that current to those specific electrical or electronic components so they effectively carry out their appropriate functions.

[0032] The present invention works best in following manner that includes the frame having a cuboidal body 1 developed to be held by a user for positioning the body 1 over a paper sheet and the body 1 is configured with a pair of telescopic rods 2, each integrated with a suction unit 3 for affixing the body 1 over a ruler present over the sheet. The artificial intelligence based imaging unit 4 detects dimensions of the ruler, based on which the microcontroller actuates the rods 2 to extend for positioning the rods 2 in contact with the upper surface of the ruler, followed by actuation of the suction unit 3 for securing the body 1 over the ruler. Also, the angle sensor detects angle of inclination of the ruler with respect to the sheet, in accordance to which the microcontroller actuates the rods 2 to extend/retract for orienting the ruler parallel to the surface. Also, the proximity sensor synced with the imaging unit 4 detects presence of the user's hand over the ruler while the user is drawing lines over the sheet via the ruler, and in case the user's hand is in close proximity while drawing lines, the microcontroller activates the speaker 5 o notify the user regarding the detected alignment/ position of hands. Also, the microcontroller actuates the motorized clippers 6 to adjust position of the ruler, followed by actuation of the speaker 5 to notify the user regarding the detected moisture present on the sheet.
