A complementary bipolar transistor having a lateral npn bipolar transistor, a vertical and a lateral pnp bipolar transistor, an integrated injection logic, a diffusion capacitor, a polysilicon capacitor and polysilicon resistors are disclosed. The brackets engage the instrument tray and are adapted to facilitate installation and removal of the brackets from the tray. The provided video signal is one that is created by upsampling a video signal recorded in a format having a lower sampling rate. The transmitters can be operated asynchronously. A region motion phase value is assigned to each region, based on the block motion phase values for the blocks in the region. The system and method can be used to decrease effective laser pulse-to-pulse variability in lithographic lasers, allowing adequate dose control using a minimum number of pulses.
