How To Recycle Electronics

Here are some advice for the safe recycling of your own electronics. The best and also the safest action you can take to get rid of your electronic and digital pieces is to dispatch it to the closest recycling center. Ensure you choose recycling facilities that supply a neat and ecologically safe way for recycling electronic and digital items. These recycling centers hold the essential products to break down your electronic pieces into useful sources.

Advancements in technologies allow it to be practically essential to invest in a brand-new personal computer at the least every 3 years, if you want to keep updated with the most current software applications and technological innovation. All you have to do to get a brand-new personal computer is to take a look at a number of computer system brand names and units, make reviews based on capabilities and rate, and finally decide on the perfect computer system to order.

However the complicated part of purchasing a laptop or computer depends on eliminating your old computer system. It’s not possible to just eliminate your old computer system in the garbage dump as computers, and also other electronic gadgets have a lot of toxic waste. Electrical pieces can pollute the planet. Electrical things for example cellular phones, computers along with gaming systems all contain mercury, lead, dangerous plastic materials and other chemicals that can cause destruction to the earth if not disposed of thoroughly.

Additionally, they usually have heavy duty air filtration systems which help in keeping the outside air free of both pollutants and toxins right after its recycling system. If you do not know of any recycling facility in your own district, you just need to perform an internet hunt for one. After typing the keywords and phrases ‘electronic recycling center’ or ‘how to recycle electronics’ and your zip code, you are provided with a list of various recycling centers within your neighborhood. In case you have small electronic tools to recycle, you could as well drop them off in the recycling unit before heading off to the office.

However if it is something big, you can have the recycling center dispatch individuals to gather your machines for its secure and effective disposal. Just simply because you have moved on for some other, new products, does not mean the older electronics can’t be utilized. With the help of these tips, it is possible to safely recycle any electronic devices you might have, to make our living earth a a lot safer place to inhabit.

Advances In Silicon Technology Enables Replacement Of Quartz-based Oscillators

Introduction

With a market size estimated at more than $650M and more than 1.4B crystal oscillators supplied annually, quartz crystal oscillators have long been the preferred choice for clock generation in consumer, computing, and communication applications. Quartz oscillators are available in a wide
range of frequencies, package sizes, and stabilities. In addition to providing excellent jitter performance, quartz oscillators are available from a broad range of suppliers.

Quartz Resonator Based Oscillators

Crystal oscillators require a unique quartz resonator for each frequency. The crystal oscillator assembly process requires the quartz to be cut, x-rayed, lapped, mounted, and sealed into the
final package . Fabrication of these resonators becomes increasingly difficult at frequencies over 100 MHz because the resonator must be manufactured to very tight tolerances. The complexity of the manufacturing process is subject to poor yield at multiple steps within the
process forcing material restarts and overall production delays.

In addition to lead times, reliability is a chief concern with quartz oscillators. Quartz oscillators are susceptible to contamination which can affect both the center frequency and the ability of the XO to start up reliably. If an oscillator fails in the end application, often the entire system fails because the oscillator provides critical timing for the electronics.

MEMS Resonator Based Oscillators

The industry has long been searching for a technology that enables the replacement of quartz oscillators with a solution that addresses lead time and reliability concerns while providing performance on par with quartz oscillators. Over the last several years, micro-electromechanical
system (MEMS)-based oscillators have emerged as a possible replacement technology for quartz oscillators. MEMS-based oscillators provide an alternative solution to quartz by replacing the
quartz oscillator with a CMOS-based mechanical resonator.

Si500 Silicon Oscillator

Silicon Labs Si500 silicon oscillator leverages a standard IC manufacturing flow. The silicon oscillator is fabricated using standard submicron CMOS technology and standard low-cost
plastic packaging that does not require a hermetic seal. The silicon oscillator is factoryprogrammed at test to a specific frequency, signal format, and supply voltage.

Si500 Technology Overview

The heart of the architecture is a low phase noise, frequency flexible LC oscillator. Using innovative mixed-signal analog circuitry, the oscillator is compensated for frequency variation due to operating temperature range, aging, initial frequency accuracy, supply voltage change, and output load
change. The silicon oscillator supports a wide frequency range, generating any output clock frequency from 0.9 to 200 MHz. Selection of the frequency, output type, supply voltage, and output enable (OE) is stored in non-volatile memory (NVM). At power-on, the Si500 performs a
self-calibration using these stored parameters and configures itself for operation.

Temperature Stability

Temperature stability refers to how much the oscillator frequency varies over the operating temperature range of the device. For the Si500 silicon oscillator, tight temperature stability is achieved through dynamic temperature compensation. The device has an on-board temperature
sensor that, upon detection of a temperature change, dynamically adjusts the frequency of oscillation of the LC oscillator to maintain a stable output frequency.

Aging

All oscillators experience drift in the frequency over long periods of time. The effect is called aging and is an important specification in the overall frequency stability budget. Aging behavior is dependent on several aging mechanisms including the design of the resonator, the assembly of the oscillator, the contamination level surrounding the resonator, the design of the electronics, and the operating temperature. To determine an upper bound on aging performance, it is
necessary to control as many of the mechanisms as possible and to verify conformance through extensive aging studies.

Reliability

Quartz oscillators require hermetic packaging for the crystal. Package leaks or internal contamination can lead to long term frequency aging, or if severe enough, can even prevent oscillation. Consequently, oscillator manufacturers minimize contamination by using costly, hermetically sealed ceramic or metal packaging and special processing. Done properly, reliable operation can be achieved, but package and assembly costs will be considerably higher than with non-quartz CMOS only devices. Being a mechanical device, MEMS resonators are susceptible to the same contamination issues and also require hermeticity.

Shock and Vibration

Shock and vibration can also limit the reliability of quartz-based oscillators. Quartz crystals are mounted above the oscillation electronics using epoxy or metal clips supported on one side only. Attaching the crystal on one side places the crystals center of gravity far away from
the support point allowing the crystal to swing like a diving board when exposed to vibration.

Jitter Performance

Period jitter is a key specification for oscillators since it impacts the setup/hold time, noise margin, or bit-error rate of systems that require alignment between clock and data. Period jitter describes how much any period may deviate from the ideal clock period and is used to determine the setup/hold time margin within a digital system. The amount of margin required depends greatly on the how many timing violations (i.e., bit-errors) a system can handle. In most designs, no timing
violations are allowed over the lifetime of the product, so the amount of margin is quite large. Period jitter is related to phase noise[2] and is often dominated by phase noise at far offset frequencies up to half of the clock frequency.

Programmable Output Buffer

Because the Si500 can generate frequencies across a large range (0.9 to 200 MHz), the output buffer design must provide easy connectivity for the many common receiver formats and voltages used in this range. The Si500 employs a programmable output buffer with support for both
differential and single-ended formats while easing the design effort by incorporating common external components.

Conclusion

With advances in mixed-signal CMOS technologies, silicon oscillators like the Si500 are now competitive with oscillators that use traditional quartz or MEMS resonators. By eliminating the need for these mechanical resonators, the Si500 offers significantly improved reliability when
shock, vibration, and oscillator start up are considered. In addition, the Si500s simplified manufacturing flow reduces cost and enables short predictable lead times when compared to traditional quartz based oscillators.

Importance of Drug Knowledge for the Manufacturers

An important part of drug studies, clinical research involves in testing new medicines, devices and surgical techniques on human volunteers. Bioavailability and Bioequivalence (BA BE) Studies in clinical research involve comparing the formulation of different drugs from different manufacturers or comparing the same drug prepared in different batches by the same manufacturer.

All drugs will have an active ingredient that does the main work of the medication. Bioavailability is a term that defines the extent to which this active ingredient is absorbed in the blood. The absorbed active ingredient should then be transported to the active site where it reacts to provide the right results. The level of absorption will determine the extent of the efficacy of the drug. BA or Bioavailability studies track and measure the amount of active ingredient absorbed in the blood. Based on these statistics for clinical research methodologies are then followed to determine the effects of the drug on the human being.ng.

The bioavailability studies of two drugs of almost similar formulations are studied to compare the effect and absorbency of their active ingredients. If the absorbance and therapeutic effect of two different drugs are similar, then they are said to be bioequivalent. Such drugs can be used interchangeably. For two drugs to be bioequivalent, they should pass various criteria. Their basic formulations should be similar, and the rate of absorbance should also be close. The dosage levels of the two drugs should be same and they should take relatively the same amount of time to reach the target site.

So, what are the benefits of doing BA/BE studies? First, they help us understand and determine if the active ingredient has any beneficial effect on the body. Secondly, if a drug manufacturer comes up with a different version of a medication that has an active ingredient that has already undergone a BA/BE clinical research studies, then they can just market that drug with minimum testing. The statistics obtained from its bioequivalent will prove to be good enough for satisfying the regulations. All drug manufacturers should do the BA/BE studies of the drugs they produce before it is introduced in the market.

This study is meant only for generic drugs and not specialized medicines. This clinical research study doesn’t have many phases and also involves just a small number of healthy volunteers. Moreover, the research is concentrated only on the active site, which means the studies can be done quickly and easily.

Proper Disposal Of Consumer Electronics Is Important

When you think about consumer electronics, you may think of equipment you use every day; like televisions, mobile phones and personal computers. What you may not even consider is that each year, the United States alone generates almost 3 million tons of commodity and electronic waste (or e-waste) through the disposal of damaged, defective and obsolete devices, such as that cordless phone that quit working for you or those mobile phones you threw away because you wanted the latest models. Let’s look at where that e-waste ends up after it’s tossed away and the effects it has on you and the environment.

Because of the difficulty and cost of recycling electronics, as well as spotty enforcement of legislation regarding e-waste exports, vast amounts of used electronics have been sent to countries such as China, Kenya and India. Lower environmental standards and working conditions make processing e-waste more profitable yet dangerously hazardous in those countries. Being mindful of e-waste disposal is a big concern. There are facilities out there that specifically deal with this hazardous material correctly.

When electronics are handled and sorted properly, e-waste is a valuable source of secondary raw materials. However, they are a major contributor of toxins and carcinogens when clumsily treated.

Fast paced technology changes, low initial cost and actual planned obsolescence have given way to a growing problem around the globe. Uncontrolled burning, disassembly without safety measures in place, and haphazard disposal practices are causing environmental and health problems.

Toxic and carcinogenic substances in waste from consumer electronics include lead, cadmium, mercury and polychlorinated biphenyls (PCBs). When not handled properly, these substances can seep into soil where food is grown. They can be eaten or absorbed by animals in our food chain. Illegal burning of these electronics causes toxic fumes to be emitted, which are inhaled by animals and humans and depletes the ozone.

There are many ways in which these substance cause serious health risks. Lead, cadmium and mercury levels can build up in the body over time causing damage to the central nervous system, renal failure and cell damage. PCBs are known carcinogens.

Think about it the next time you indiscriminately throw away those cordless phone batteries or that camcorder that is older than your parents. Proper disposal through an e-waste recycler helps save our environment. With the potential for mercury, cadmium and lead leaching into the soil and contaminating the food chain, as well as PCB exposure causing cancer, some thoughtful consideration of use, reuse and disposal of consumer electronics is essential.
