Computer Aided Design

Constant variables are variables that, once initialized, do not change in value. They are effectively the same as literal constants, except that you can use symbolic names to make it easier to understand the meaning of the program.

For instance, in a trigonometry program, it is easier to use the identifier PI than it is to use the literal 3.1415926535897932. Also, if you have a constant that might be adjustable, such as a factor in an equation, naming it allows you to change its value by changing only one line of code, rather than seeking out all of the lines of code that refer to the factor.

Constant variables are also candidates for being placed in read-only memory, potentially making the program more secure.

Literally it means what you asked. 'Cad is brí' means what is the meaning / what does it mean. For example; cad is brí le thit mé? Thit mé means I fell, it is in the past tense. Hope that helps, but it just means what is the meaning of.....

Making models involves creating representations of complex objects or process.

Ascend = Go up. 1, 2, 3, 4...

it means stupied, constipadid, anyone should know that!

Sectional views are used to shows the internal detail of an object. The drawing will show the interior part of an object as if it was cut in half or quartered. essentially a flat plane passed through a 3 dimentional object highlighting all the internal detail

A wireframe model is an edge or skeletal representation of a real-world 3D object using lines and curves. -Frank-

Proximity switches open or close an electrical circuit when they make contact with or come within a certain distance of an object. Proximity switches are most commonly used in manufacturing equipment, robotics, and security systems. There are four basic types of proximity switches: infrared, acoustic, capacitive, and inductive.

Infrared proximity switches work by sending out beams of invisible infrared light. A photodetector on the proximity switch detects any reflections of this light. These reflections allow infrared proximity switches to determine whether there is an object nearby. As proximity switches with just a light source and photodiode are susceptible to false readings due to background light, more complex switches modulate the transmitted light at a specific frequency and have receivers which only respond to that frequency. Even more complex proximity sensors are able to use the light reflected from an object to compute its distance from the sensor.

Acoustic proximity sensors are similar in principle to infrared models, but use sound instead of light. They use a transducer to transmit inaudible sound waves at various frequencies in a preset sequence, then measure the length of time the sound takes to hit a nearby object and return to a second transducer on the switch. Essentially, acoustic proximity sensors measure the time it takes for sound pulses to "echo" and use this measurement to calculate distance, just like sonar.

Capacitive proximity switches sense distance to objects by detecting changes in capacitance around it. A radio-frequency oscillator is connected to a metal plate. When the plate nears an object, the radio frequency changes, and the frequency detector sends a signal telling the switch to open or close. These proximity switches have the disadvantage of being more sensitive to objects that conduct electricity than to objects that do not.

Inductive proximity switches sense distance to objects by generating magnetic fields. They are similar in principle to metal detectors. A coil of wire is charged with electrical current, and an electronic circuit measures this current. If a metallic part gets close enough to the coil, the current will increase and the proximity switch will open or close accordingly. The chief disadvantage of inductive proximity switches is that they can only detect metallic objects.

Proximity switches are used in manufacturing processes -- for example, to measure the position of machine components. They are also used in security systems, in applications such as detecting the opening of a door, and in robotics, where they can monitor a robot or its components' nearness to objects and steer it accordingly

1 disadvantage is that it might not always be as accurate as you want it to be

IF you count the base five, if not 4. I would know because i made a cardboard one and then i found out it was 4 so i had to startover. It sucked.And i thought it was three!

To make a full subtractor, you need an XOR and a NAND gate.

It is not CAD pump, It is CADD pump i.e CADD-Plus intravenous infusion pump. You can refer to stedman's cardiovascular and Pulmonology words for reference in this regard. Regards M. Usha.

The "limits" define the area of your "drawing board" (field). It is not neccessary to set them to form an inordinately large, or infinite field at the start of a drawing, as they can be altered later if needs be. It is neccessary to set them, however, as in certain circumstances the program uses zero as the default setting. If you blithely accept this setting you will have no field in which to produce your drawing.

Direct data capture is the collection of data for a particular purpose (e.g. barcodes being read at a supermarket so that the product can be identified or account details being read directly from the chip embedded in the credit card.)

Indirect data capture is the collection of data as a by-product from data collected for another purpose (e.g. using data collected from reading barcodes at a supermarket till to work out the stock levels or using data collected from reading barcodes to see whether an item is selling well.)
