Abstract: The calibrating breathalyzer comprises an alcohol sensor, a non-volatile memory, a processing unit or processor, a display and a housing to house these components. The processing unit can calibrate the breathalyzer using the user's body as a simulator based on the user's metabolism rate, type and amount of alcohol consumed by the user. The processing unit determines a sample time to receive a breath sample from the user based on a time to a predetermined calibration point from the drinking start time calculated using the user's metabolism rate and the determined maximum alcohol level. The BAC % measurement based on the user's breath sample at the sample time is used as a reference point in calibrating the breathalyzer.

Abstract: A digital television (DTV) and a method of providing a GUI using the DTV are disclosed. The method of providing a GUI in a DTV comprises: first displaying an image on a display unit provided on the DTV; receiving a display command of a first GUI; and second displaying the image and the first GUI such that a different spatial depth is formed between the image and the first GUI according to the received display command.

Abstract: In a method of forming a quantum dot having nanometeric size and a method of forming a gate electrode including the quantum dot, a first layer including a first material is deposited on the substrate. The first material has first atoms that are superbundant and bound with the weak bonding energy in the first layer. A second layer is deposited on the first layer. The second layer comprises a second material including second atoms that are capable of migrating into the first atoms. The first atoms are migrated into the second layer and the second atoms are migrated into the first layer, so that the second atoms are arranged in the first layer. Each of the second atoms in the first layer is formed into a quantum dot. An electrode layer is formed on the first layer after partially etching the second layer, and then a gate electrode is formed by patterning the electrode layer.
