Wirelessly Charging Mobile Devices from Ambient RF Sources ABSTRACT: Wireless charging is any of several methods of charging batteries without the use of cables or device-specific AC adaptors. Wireless charging can be used for a wide variety of devices including cell phones‚ laptop computers and MP3 players as well as larger objects‚ such as robots and electric cars. Radio charging is used for charging items with small batteries and low power requirements‚ such as watches‚ hearing aids‚ medical

|LASER ALIGNMENT THEORY Modern optical metrology uses precise lines and planes in space from which measurements are made. Because this method creates these features using light it has become known as optical tooling. The 35 year old historical development and current technology of laser instrumentation as used in optical tooling is discussed in detail. This includes the how the measurements are made‚ applications‚ and the technology of alignment lasers and position sensing targets developed for

INTRODUCTION: This is a standard circuit which can be used to adjust the brightness of mains lights and the speed of AC motors. It uses a triac‚ diac and has a radio-frequency interference (RFI) noise suppression circuit built into it as well. The circuit controls the average power to a load through the triac by phase control. The AC supply is applied to the load for only a controlled fraction of each cycle. The triac is held in an OFF condition for a portion of its cycle then is triggered ON at
