A brake is disclosed for use with a cart. Such a device is obtained by a phase shifting network in a quadrature branch of the demodulator having a series arrangement of a resistor and an capacitor coupled to an inductor coupled to ground. Sub-areas corresponding to areas of the surface for which an aerodynamic heating analysis is to be performed are identified. The crimping tool further includes a handle portion having a gripping portion suitably configured to be manually grasped. A gate driving unit applies the gate pulses to the gate lines selected according to the gate control signal. At least one amplifier is provided, including a first input node to receive an output signal from the output node of a selected pixel and a second input node connected to a reference voltage source provided as a reference to reset a selected pixel.
