Coping With Obsolete Electronic Components

As technology progresses, some things are bound to become obsolete. New developments require new products. This is true for most of the things that we use, and electronic components are among them. This is how it will continue to be. The new will constantly enter the scene to take over from the old. That is how progress works after all.

There are several reasons why electronic components may become obsolete. One of the most common reasons is that the products that use the components may no longer be in use. If a product has a short life cycle, it follows that the components that it uses shall also have a short life cycle. Thus, when that product goes out of the market and manufactures cease, it will be the end of life for the components that it uses.

One of the reasons for components becoming obsolete is the impact of governmental policies. Some time ago, when the European Union decided to ban some hazardous parts, component buyers did face some problems. In this case, among the parts to go were those that were not lead-free. With the EU ban in place, those who used components using lead or the other banned substances were hit hard. This was especially a problem in places like the United States, where the law pertaining to hazardous substances had not been put into effect.

One of the effects that the banning of specific components have is that entire machinery may become unusable because of it. For instance, it is not possible to use non-leaded components in machinery that uses leaded parts. This is because the temperatures that each require are very different. Thus, if manufactures cease for one part, several others may be facing the ends of their lives.

Of course, a number of pieces of the various components shall remain with suppliers. However, it is safe to say that finding these components can turn into quite a headache. Some semiconductors can be really hard to find and it may become difficult to locate obsolete integrated circuits. End of life electronic parts remain with a few suppliers to assist people who have to continue using older machinery.

Nowadays, however, it has become less difficult to locate the people who do store obsolete electronic components. An Internet search using the words “end of life electronic components” should provide effective results. With buyers and suppliers looking for trade in electronic components on the Internet, life has become a whole lot simpler.

5 Critical Components of a Sonobuoy

The sonobuoy is device that gathers and transmits information from the world’s oceans. It is a technology that dates to the first world war, when it was developed by the military to track the activities of passing vessels. Today, a wide range of industries utilize the information gathering and transmitting capabilities of the device, from military groups, to oil and gas exploration, to scientific groups. They are used to monitor a number of types of ocean activities. Migration habits of marine life, varying ocean temperatures, changing currents, ship activity, and ocean terrain are only a few of the many things that a sonobuoy can be used to monitor or track. While they can be highly technical devices, they mainly consist of a few critical components.

1. Floatation device

All of them have some form of flotation device. This allows a person to deploy it at sea, where it can float for a period of time and record and transmit data and not have it sink to the bottom of the ocean. The top of it floats and the bottom is submersed, so it can gather information. In many cases, the other components are connected by cables that float freely. While the idea is simple, a piece of equipment attached to a buoy, the finished product can be highly technical.

2. Transmitter

The transmitter is the part of the sonobuoy that transmits the data it collects to another computer for storage and processing. It is an essential component, because many sonobuoys are lost in the violent conditions, making retrieving them difficult or impossible. By transmitting the data, the team processing the information is better able to get the information they need.

3. Sonar equipment

Not all sonobuoys have sonar equipment, but it is a common component. Those that have them are called active. Those that do not are called passive. The device emits a ping and then measures the time it takes for the sound waves to bounce off of something and return. This helps the controller paint a picture of the environment in which the sonobuoy was deployed. The product has helped create detailed maps of previously unknown parts of the ocean.

4. Rugged construction

Sonobuoys are used in one of the most violent and difficult environments on earth… in the middle of oceans. Severe weather, animal encounters, corrosion, salt, and violent movements are all everyday occurrences for the average buoy. They need to withstand the elements long enough to gather the information for which they were deployed. It is important to make sure that the product you purchase has been thoroughly tested for durability and reliability. The quality of the data collected depends on the quality of the tracking equipment.

5. Recording equipment

While most every sonobuoy has a transmitter, some have recording device on them. It is possible to retrieve the information manually, or have the device only transmit the data periodically. Recording equipment is helpful for times when weather or other conditions do not permit the transmission of data. The information can be stored until a time when it can be safely retrieved.

The Components And Peripherals Necessary To Assemble A Basic Modern System

In this case, there are components and peripherals that are necessary in assembling a modern personal computer (pc). These basic personal computer components are:

The motherboard: the motherboard is the core of the system. It really is the pc, everything else is connected to it and it controls everything in the system. Without a doubt, the most important component in a personal computer is the motherboard. Virtually every internal component in a pc is connected to the motherboard, and its features largely determine what your computer is capable of, not to mention its overall performance.

The processor: the processor is often thought of as the engine of the computer or the power house. It is also called the central processing unit (CPU).

Memory (RAM): The system memory is often called the Random Access Memory (RAM). This is the primary working memory, which holds all the programs and data the processor is using at a given time.

Case/Chassis: The case is the frame that houses the motherboard, power unit, disk drive and any other physical component in the system.

Power Unit: The power unit feeds electrical power to the internal components in the system.

Floppy Drive: The floppy drive is a low capacity removable media, magnetic storage device. Many recent systems use other type of removable magnetic or USB – based flash memory device instead of floppy drive for removable storage.

Hard Drive: The hard drive is the primary high capacity storage media for the system. These are to say that all the information in the system is being stored in the hard drive.

CD/DVD Drive: CD (compact disc) and DVD (digital versatile disc). They are used for installation and they are relatively high capacity removable media.

The Keyboard: The keyboard is an input device, used to input data into the system. The keyboard is the primary device on a system that is used by human to communicate with and the system.

The Mouse: This a pointing device.

Video Card: The video card controls the information you see on the monitor. Without the video card no information will be display on the screen of the monitor.
