The present invention relates to an electric power saving apparatus wherein light energy is irradiated to a semiconductor device, with the light energy emitted when a voltage is supplied to a transmission line, such that the wavelengths of the electrons on the transmission line, along which a load-driving current flows are elongated, a nd the spin motions and vibration states of the electrons are ...

Systems and method for synchronizing audio and video signals are described. The audio and video signals are tagged in an encoder. The tagged signals are transmitted across a network. The tagged signals are analyzed to detect phase errors or lip synch errors between them. A synchronization signal is generated in response to such lip synch errors.

System for controlling an ultrasonic handpiece of an ocular surgical system, such as a phacoemulsification system. First and second signal sources generate first and second drive signals. The first signal is at a first frequency and is used to drive a cutting tip of the handpiece with a first type of motion. The second signal is at a second frequency and is used to drive the cutting tip with a sec...

A system and method are provided for providing electromagnetic (EM) measurement-while--drilling (MWD) telemetry capabilities using an existing m ud- pulse MWD tool. An EM tool intercepts the output from the mud-pulse tool and generates an EM signal tha t mimics a mud--pulse pressure signal. The EM signal is intercepted at the surface by a receiver module that conditions the signal and inputs the s...
