A focal plane staring sensor is provided that includes an M\xd7N sensor, where M is a number of rows of sensor pixels in the sensor and N is a number of columns of sensor pixels in the sensor, where M and N are integers greater than one. Moreover, the section for putting round an ankle 12 is formed by linking the idler ends 10 and 10 of both the horizontal band pieces 1 and 2 each other by given means. The intensifier uses a control valve and operating system which includes a fast-acting 52-way solenoid valve having a feedback loop connected to a control system which includes a micro-processor that controls valve actuation. An upper cymbal is supported by the control shaft and oriented over the lower cymbal. The invention also relates to novel salts and solvates, in particular hydrates of salts of said compound, as well as to their use as medicaments.
