Methods and systems are disclosed for automatically installing software applications on multiple target computers having different computing platforms from a central location. Active areas of the transistors are disposed in a substrate, and longitudinal axes of the active areas of the transistors are all parallel. One of the embodiment of the device comprises a source of vacuum with a periodic controlling device, an isolated chamber adapted to accommodate a to-be-exposed organ therein, a source of a low-frequency pulsed magnetic field with an inductor generating a magnetic field in the place of location of the organ to be subjected to exposure. A pair of distractors are provided. A request to play a second interactive television signal at a second electronic device that is communicatively coupled to the first electronic device is received.
