Innovation in Battery Charging With STMicroelectronics’s New Innovative Solar Charger

0

STMicroelectronics, a global leader serving customers across the spectrum of electronics applications has announced a new IC which will significantly increase charging efficiency either indoor or outdoor, using the sun’s radiated energy, enabling longer mobile equipment runtime and avoiding an unexpected lack of power when a mains connection is not available. The small strips of solar cells seen in the front panels of today’s small portable consumer, healthcare and security devices are set to become a more valuable source of free energy with help from a new advanced battery charging IC from STMicroelectronics

 

STMicroelectronics’s SPV1040 is a step-up DC-DC converter tailored to be used as solar battery charger for portable applications to employ Maximum Power Point Tracking (MPPT), an innovative technique for collecting the maximum possible energy from solar cells. It can be connected to strips of even just a few cells, allowing use in products such as portable healthcare devices, watches, calculators, wireless headsets, toys, or mobile phones. The battery charger and MPPT technology can also be used in equipment such as sensors and security cameras.

 

The MPPT algorithm embedded in the SPV1040 dynamically adjusts the charger’s input impedance to ensure perfect matching with the solar cell, thereby maximizing energy transfer to the battery and dramatically improving overall system efficiency. Without MPPT, changes in the solar cells caused by temperature, ageing, dirt or unit-to-unit variation can produce mismatches that significantly reduce the energy harvested.

 

Major features of SPV1040:

Input-voltage range: 0.3V to 5.5V

Integrated low-loss synchronous rectifier and power switch

Up to 95% efficiency

Shutdown pin to aid system-level power management

Thermal shutdown and protection circuitry to improve battery and overall system safety

 

Available in the TSSOP8 plastic package, the SPV1040 is in full production, priced at approximately $2.00 in quantities of 1000 units. Alternative pricing options are available for larger quantity orders. Evaluation boards and technical documentation are also available.

In Tech Pyramid, Africa Must Move From The Downstream To The Upstream Where Wealth Is Created

0

Technology is the leader of the enterprising world. And it leads using a constitution. Unlike the traditional political structure, this constitution is Algorithms written by engineers, scientists, etc and not congressmen and politicians.

 

The global competition is largely who has the best technical group to write the best one; in this case, Algorithms, that comprise of patents, technical processes, tools, and so on. As a nation develops, adopts, applies and diffuses appropriately the contents of this constitution, it elevates the lives of its citizens. The more innovation a nation pursues, the more it refines this constitution.

 

Economists have shown a correlation between Knowledge Economy Index (KEI), productivity and standard of living. The challenge for any nation is to improve its KEI number. Doing that involves good education, economic regime and other variables that help to improve technology capability.

 

The age of natural resources dominating global commerce and industry is gone. What matters now is creating knowledge and applying it. Some nations will create, others will merely consume. But wealth is concentrated at the creative stage and nations that focus on consuming, without creating technology will not prosper.

 

Even with abundance of natural resources, which in many instances, the consuming nations cannot independently process without the knowledge partners will not change this trajectory of limited national wealth without technology creation.

 

On this basis, I separate the two layers where nations use and compete with technology as upstream and downstream layers. It is like a two layer pyramid where the downstream is at the bottom with the upstream seated on top. What happens here is that some nations focus on the downstream layer while others combine both the downstream and upstream layers.

 

The most advanced nations combine the two layers as they seek international competitiveness. They provide technology roadmap that looks at the future and have plans to take advantages that technology brings. They create and develop things and in the 21st century are classed as knowledge driven economies. In those nations, there is planning for continuity and technology succession.

 

For the other nations, usually developing, they compete at the technology pyramid primarily at the downstream layer. They lack the know-how to create things and commercialize technology intellectual properties. The nations are not driven by technology, rather commodities. They are prone to trade shocks and are usually economically non-vibrant. They fail to create wealth using technology and participate in the pyramid as consumers or prosumers.

 

Let me illustrate using Nigeria where they speak the language of petroleum. In the petroleum industry, there are the downstream and upstream sectors. While the upstream focuses on exploration of crude oil, downstream does the distribution and marketing.

 

The money is in the upstream sector, a major reason we have the foreign partners concentrated therein. That is where the knowledge creation is done and utilized in the industry. I am cautious to say, without the knowledge partners in Nigeria, helping to explore this crude oil, Nigeria cannot mine this product. Verdict: the oil will be there and of no tangible economic use.

 

This will follow a pattern where villages have water underneath them but no drilling expertise to harness the water for cooking and drinking. That is the problem of anchoring national strategy at the downstream level. It lacks inventiveness.

 

In Africa and many developing countries where ICT has been embraced, they rarely know that there is more value than what ICT gives them. Sure ICT has helped many developing countries to improve their business processes, tools and people. They are so excited on the powers of quicker and faster communication. They savor the wonders of email, Internet and mobile phone and many more. These experiences are primarily on marketing, distributing and installation of these ICT systems. They rarely make them and can only play at the downstream layer.

 

There economists point out repeatedly the innovations ICT has brought to the economies. I agree, ICT is wired for innovation in so many areas. Nonetheless, the good news is that there are more benefits up in the pyramid if you move up to the upstream layer. By not creating technology, our techno-economic benefits are limited and this will not change until we move up the pyramid.

 

Though this point can be illustrated with any technology, I will use the ICT because it is common and familiar to people. I have already illustrated the point in the petroleum industry where many developing nations depend on petroleum refining technology of the developed countries to extract the oil. Even if they develop technologies for the distribution, the upstream idea will triumph. Nations make more money to license technologies at the upstream level compared to the downstream.

 

Back to ICT, the upstream level will involve designing computing systems, cellphones, routers, device drivers, and all other infrastructures that enable ICT revolution. Instead of importing the latest cellphones, we will think how to design them. In 80% of the developing nations where mobile technology is used, less than 2% of the technologies are designed and manufactured there.

 

Yes, there are businesses that distribute and sale these gadgets and make marginal profits. They can import a laptop from China at $500 and sell to their customers at $650. Because the barrier to entry is so weak, the margins are small. Everyone is selling and there are shops everyone. They are technology firms to their nations because they can load the software and configure the networks and get the laptop working.

 

Compare that with giants like Intel and AMD that take a piece of sand (silica) and process it. At the end, that piece of sand of say a $1 can be sold for $3,000 because of the knowledge involved to transform the sand to a microprocessor. That is knowledge and the very best of human imagination and creativity. It is playing technology at the upstream level and that is where the value is.

 

Nations win at the upstream level because the sale margins are so huge because the products are niche and in most cases innovative with few players internationally. It is not just the trade or margins. Upstream technology layer create good jobs, whether in developed or developing nations. Some of the best jobs in Africa are in the oil giants where upstream technology rules. You create enviable good jobs for the citizens. They have the money to spend and lift other areas of the economy. They hold jobs that bring honor and dignity and they use their brains to shape the world.

 

You can make the same case for Pharmaceutical firms that mix elements, compounds, etc to create drugs. Some of the drugs are really expensive but the ingredients are cheap. People pay for the R&D invested in developing that drug. In developing nations, they focus on marketing and selling the drugs. As in petroleum, ICT, it is all about the downstream. Why the big Pharma can have margins of 1000%, these entities can barely command 6% margins.

 

So in essence, in this century, there are opportunities for nations. For developing nations, if they continue to compete at the downstream layer of the pyramid, they will find it hard to move forward since competition is basically synonymous with technology. There is more risk, more knowledge requirement and more value at the upstream. And we need to get there.

 

How do we do that? Our nations must have fundamental changes in our national policies on technical education or better Science, Technology, Engineering and Mathematics (STEM). That is the answer. I believe in knowledge and education evolves it. It is about expansion of commitments on microelectronics, nanotechnology, biotechnology, mathematics, chemistry, physics, computer science, engineering, medicine, and so on and within a generation we can become players at the upstream level of technology pyramid. And reap that great value therein.

M-Chanjo Simplifies Immunization Program – SMS Ensures Your Child Never Miss A Shot

0

M-Chanjo by M-Chanjo is an application that creates a centralized registry for children who should be in an immunization program, creates SMS reminders as a way of creating awareness and reminding patients of scheduled appointments, and manages patients’ appointments through an automated system.

 

Basically the firm is poised  to reduce the rate of child mortality especially in the developing world. M-Chanjo comes from the Swahili word for vaccine; Chanjo. The name is derived from the realization that it could approach most problems in the developing world from a preventive perspective. So leveraging technology, the firm could innovate grand ideas that have great social impact rather than waiting to derive solutions after problems have occurred.

 

Their firm’s key solution is based on a mobile platform that raises awareness on child immunization. The solution also enables easier management of infant medical records by health personnel via any Internet capable mobile device. The firm firmly believes that in raising awareness in regards to immunization , it can prevent the more than 1,000,000 infant lives lost each year due to preventable diseases such as Measles, Polio, Pneumonia etc
