Wireless Power Transmission: Unlocking the Potential of a Cordless Future

USB 3.0 Speeds Up Performance on External Devices

The USB connector has been one of the greatest success stories in the history of computing, with more than 2 billion USB-connected devices sold to date. But in an age of terabyte hard drives, the once-cool throughput of 480 megabits per second that a USB 2.0 device can realistically provide just doesn't cut it any longer.

What is it? USB 3.0 (aka "SuperSpeed USB") promises to increase performance by a factor of 10, pushing the theoretical maximum throughput of the connector all the way up to 4.8 gigabits per second, or processing roughly the equivalent of an entire CD-R disc every second. USB 3.0 devices will use a slightly different connector, but USB 3.0 ports are expected to be backward-compatible with current USB plugs, and vice versa. USB 3.0 should also greatly enhance the power efficiency of USB devices, while increasing the juice (nearly one full amp, up from 0.1 amps) available to them. That means faster charging times for your iPod--and probably even more bizarre USB-connected gear like the toy rocket launchers a  nd beverage coolers that have been festooning people's desks.

Wireless power transmission 

is a technology that allows the transfer of electrical energy from a power source to a device or system without the need for physical wires or cables. It is based on the principle of electromagnetic induction or resonance, where energy is transmitted through electromagnetic fields.

The concept of wireless power transmission has been explored for several decades, and various methods have been developed to achieve efficient energy transfer over short to medium distances. One common approach is inductive coupling, where a primary coil connected to a power source generates an oscillating magnetic field. This field induces a current in a secondary coil present in the receiving device, thus transferring power wirelessly.

Resonant inductive coupling is another method used in wireless power transmission, which utilizes the concept of resonant circuits. Both the transmitter and receiver have resonant circuits tuned to the same frequency. When the transmitter is energized, it creates a resonating electromagnetic field that can transfer power to the receiver located within the field's range.

Wireless power transmission offers several advantages. It eliminates the need for physical connections, enabling convenience and flexibility in charging or powering devices. It can be particularly useful for charging mobile devices, electric vehicles, or even powering remote sensors or medical implants.

However, wireless power transmission also has limitations. The efficiency of energy transfer decreases with increasing distance, and the power received may be lower compared to direct-wired connections. There are also potential safety concerns, as electromagnetic fields generated during wireless power transmission may interfere with other electronic devices or pose health risks.

Overall, wireless power transmission technology has the potential to revolutionize the way we charge and power our devices, offering convenience and eliminating the clutter of cables. Ongoing research and development aim to improve efficiency, increase transmission distances, and address safety concerns to make wireless power transmission a practical and widespread solution in the future.

Emerging Technologies: Shaping the Future of Innovation

Emerging technologies 

are technologies that are perceived as capable of changing the status quo. These technologies are generally new but include older technologies that are still controversial and

relatively undeveloped in potential, such as 3D printing, pre implantation genetic diagnosis and gene therapy which date to 1981, 1989 and 1990 respectively.

Emerging technologies are characterized by radical novelty, relatively fast growth, coherence, prominent impact, and uncertainty and ambiguity. In other words, an emerging technology can be

defined as "a radically novel and relatively fast growing technology characterised by a certain degree of coherence persisting over time and with the potential to exert a considerable impact on the

socio-economic domain(s) which is observed in terms of the composition of actors, institutions and patterns of interactions among those, along with the associated knowledge production processes.

Its most prominent impact, however, lies in the future and so in the emergence phase is still somewhat uncertain and ambiguous.".

Emerging technologies include a variety of technologies such as educational technology, information technology, nanotechnology, biotechnology, cognitive science, psychotechnology, robotics, and

artificial intelligence.
New technological fields may result from the technological convergence of different systems evolving towards similar goals. Convergence brings previously separate technologies such as voice (and

telephony features), data (and productivity applications) and video together so that they share resources and interact with each other, creating new efficiencies.
