A method of controlling multiple antenna signal transmission is disclosed. The processor includes execution circuitry and registers that store pointers to data structures in memory. The thickness of an anode active material layer is from 85 \u03bcm to 120 \u03bcm, and the volume density of the anode active material layer is from 1. Alternatively, the temperature profile may comprises a period of time with a temperature higher than 320 degree Celsius, wherein the period of time is shorter than 45 minutes. A substantially transparent window is provided in the patch for facilitating viewing of the openclosed status of the eye during the surgical procedure.
