Encoder

Determining the location of our fixture in space may seem like a simple task but if our goal is precision then we need to know exactly where our platform and ball screw are located at all times. To accomplish this goal, we will need to use a combination of encoders and dial gages to keep position and to check our position and precision. Encoder/Glass Scale A linear encoder is the typical way that CNC machines measure motion. It’s electro-mechanical device that creates digital signals that correlate to a position, a velocity, and a direction along a path. A linear encoder acts as a sensor and when linked to a scale it encodes a position. The sensor reads the scale and converts the encoded position into a meaningful value in the form of a digital or an analog readout. Optical linear encoders utilize a combination of light, lenses, photosensors, and a glass scale. The light source in conjunction with a lens creates a beam of light, which passes through a scanning reticle and then through the glass scale. That light is then picked up by photosensors, which creates a type of sine wave output, which the linear encoder interprets (Figure 5, Anaheim Automation, 2016). The level of accuracy created in this system is very high but the glass scale and…

In essence, everyone lives their lives in the same basic fashion: a constant cycle of encoding and storing new memories, along with the retrieval of old ones. Granted, there are those exceptions to the norm, but in the grand scheme of things they are really the outliers. Now since our brains don’t function like a video camera perfectly capturing every moment of our lives, we have to work earnestly in order to remember every minute detail which is deemed important or necessary. This is where…

also primary and secondary windings. Due to presence of rebar output of sensor varies. Rotary encoder is used to measure distance between rebar. Display is used to display results. This is portable device that you have to move on wall or column for desired output. Keywords: Arduino mega, Rotary encoder, Magnetic sensor, SD Card module. I. INTRODUCTION To inspect the rebar using ant non-destructive method has been a challenging task, especially since they are embedded in prestressed…

In today's society we have the use for technology is different aspects of our lives. We use technology in our personal life, as well as for our careers. Most industries use technology as a way to run their business in a professional and proficient manner. Today I researched on what impact technology has for Medical Coding and Billing. Medical billing process has changed a lot over the years. Before, billing was a laborious procedure and bills had to be submitted through email. Whereas,…

In case where there are not enough bits to obtain the MSB of last block, multiplier is sign extended by one bit. Therefore Modified Booth Multiplication is a technique that allows for smaller, faster circuits by recoding the numbers that are multiplied. It is a standard technique used in chip design, and provide significant improvement over long multiplication technique [6]. III. SOFTWARE DESIGN Modified Booth Multiplier consist of three basic components namely Booth encoder (BE), Booth Selector…

behaviours. Relatively simple individual rules can produce a large set of complex swarm behaviours. The main objective of this paper is the implementation of Swarm Robotics in its cheapest form with simple algorithm and application of Pseudo-decentralized system which is power efficient than the centralized system. In centralized system cameras with wide lenses have to be integrated with the existing system. Since this paper is based on the implementation of Swarm Robotics which can be used in…

Perry, R. P., & Boyd, J. E. (1972). Communicating Impressions of People: a Methodological Study of a Person Perception. Journal of Social Psychology. 86(1), 95-103. Retrieved from Communication and Mass Media Complete. Perry and Boyd are discussing a study that exams the accuracy of communication of the social judgements from one person to another. Perry and Boyd also discuss how the accuracy of the communication of social judgements is influenced by both encoders and ecoders. The final results…

Among the several peer-reviewed articles available in the internet, I read the racial differences in suicidal ideation among school going adolescents. You can the article by clicking the url below: Racial differences in suicidal ideation among school going adolescents Kumar S, Dixit V, Chaudhury S, Kenswar D K - Ind Psychiatry J The target of the study is to assess the adolescents who were attending schools, private or public, tribal or nontribal (whether they belong to a certain tribe or…

signal corresponding to 0 may change to 1 or vice –versa due to presence of noise. Figure 5. shows the basic coding block diagram of FSO communication system. Fig.5. FSO communication system with coding It is possible to improve the reliability of FSO communications system and achieve predetermined Bit Error rate (BER) by utilizing coding schemes. Forward error correcting codes (FEC) are leading an important role to get back the original message. The biggest challenge in FSO communication…

Verbal and non-verbal communications are the connections between two or more people with the exchange of thoughts, messages or information. There are three forms of communication that require skills on both the sender’s and receiver’s part. Regarding the three forms of communication, the first is interpersonal communication. According to Sarah Trenholm, interpersonal communication is “generally reserved for two-person, face-to-face interaction and has several unique characteristics; such as,…
