    Hi I am looking for someone to research and write a report answering the following questions: 1. What are the UV frequencies best suitable for surface sterilization? Are there differences between frequencies and effectiveness on different pathogens (bacteria, viruses, fungus etc? Here I am expecting a reasoning about different frequencies and their effects approx half page. 2. How much such UV light is needed to effectively disinfect a surface (dm2)? (how to measure?) 3. Can you find UV LEDs on ...

    Looking for some assistance in the design of a Class B power amplifier. This is the final stage in a servo system. The power amplifier drives a motor whose coil resistance is typically less than 2 ohms and around 100 microhenry. The power amplifier is supplied typically with + and - 24V. It works but needs some tuning. So we're looking for someone with circuit simulation experience, and with experience optimizing power amplifier output stages.

    I'm exploring a new project that will require the development of a passive rfid tag capable of being read over a distance of between 5cm and 100cm by a mobile phone. The tag will be used in clothing and so needs to be water proof / heat resistant and wearable. I have found a tag by Fugitsu which looks ideal but I need the tag to be readable by a mobile phone not an independent tag reader (Fuji tag datasheet ...

    I am designing a solar powered light consumer product, and would like your expertise to further development. It needs to be able to fully charge during the day by an inbuilt PV panel, and then run on that energy throughout the night. The size should be portable (i.e. fit inside a 150 cm^3 footprint), and the device must output bright light (around 1500 lumen). It should also be networkable through bluetooth and WiFi. The device should have a ...
