    Wireless Charging and the Water Well

    Many years ago, water wells were a primary source of water. When a family needed water, they would send someone to get some water from the well. If you did not want to run out, you had to manage the water.

    Are there any parallels to phone batteries?

    Battery Limitations for Augmented Reality Glasses

    One of the key areas of growth in augmented reality goggles is the enterprise space. These devices aim for battery life of an 8- or 10-hour shift. But these devices are power-hungry. They have displays, communications link, on-board camera and sometimes speech recognition. Longer battery life often means installing a larger battery.

    Is there a better way?

    Honey, I Shrunk the IoT Sensors

    Ever notice that batteries take up a lot of space in IoT sensors? When you open up motion detection or other home security sensors, you see that batteries take up as much of 50% of the size of the sensor.

    Is there a better way?

    Is Line-of-Sight required for Wireless Power technologies?

    When considering far-field wireless power technologies, the question of “line of sight” sometimes comes up. Sometimes, a straight line free of obstacles exists between the transmitter and the receiver. This is referred to as “line of sight”.

    Is line of sight a requirement?

    Wireless Power and the Water Tank

    When people see our demos, one of the first questions they ask is: will it charge _____ ?

    The answer depends on the average and peak power consumption of the product in question, but we typically see three categories.

    Why is Charging Efficiency Important?

    Everything else being equal, one would prefer to be efficient and not inefficient.

    But with wireless charging, the end-to-end efficiency is even more important. Here’s why:

    Can Charging a Phone be as Seamless as Receiving an email?

    Once upon a time there was no email at all.
    A few years later, you had to use a modem to dial in and check email. Remember AOL?
    Now, it’s seamless. email just gets to your inbox. You don’t have to think about fetching it.
    Can wireless power be the same?

    Wireless Power Will Reduce Landfill Toxic Waste

    Batteries power our society. Our cellphones and smart devices, children’s toys, IoT devices – all run on batteries. The Government estimates that Americans discard more than three billion batteries every year. That’s about 180,000 tons of batteries, of which 86,000 tons are single use alkaline batteries.

    What can we do to reduce this waste?

    Diffraction and Wireless Charging

    When a power beam ‘diverges’ (becomes wider), the distance of the transmitter from the receiver impacts the power capture ability. Let’s discuss the topics of ‘contained beams’ and the impact of diffraction on various power delivery methods.
