A composition for providing protection against electrical overstress comprising an insulating binder, doped semiconductive particles, and semiconductive particles. The main gearset comprises three rear-mounted gearsets whose three sun gears are interconnected and can be connected with the output element of the front-mounted gearset and with the input shaft. First, a first phase rotation indicator comprising information on phase rotation of a received signal within a first time interval is estimated. Shallow trench isolation regions define and isolate first silicon regions from second silicon regions that each include one of the recesses. Preferably, optical density is measured at a first wavelength to obtain a first optical density, and at a second wavelength, close in wavelength to the first wavelength, to obtain a second optical density. The client devices provide the players with the appearance of competing over the same course, even though they are all actually competing over courses remote from one another.
