An automated ship detection technique includes accessing data associated with an image of a portion of Earth. The device comprises a temperature-sensitive clement which can be installed inside the movable part and which is designed to emit a signal containing information on the temperature of said clement, in such a way that this signal can be received by a control unit. Each of the scan drive cells drives one of the scan lines. Further, the second transistor is configured to adjust current flowing through the first transistor based on the temperature of the first transistor. A guide groove inside a compression chamber is removed to prevent generation of a dead volume, thereby improving an efficiency of a compressor. An apparatus for quantitative assessment of visual contrast sensitivity of a subject comprising a display device, an input device, a control device, and a tangible computer readable medium.
