A disposable breath analyzing device has a housing with an inlet for receiving a breath sample, chip means for indicating the presence of alcohol, processor means for comparing the alcohol level to a threshold, LED circuit means for illuminating said LED in a steady green for a quantity less than said threshold and blinking red for a quantity greater than said threshold. The light emitting device of the embodiment includes a light emitting structure including a first conductive semiconductor layer, a second conductive semiconductor layer and an active layer between the first and second conductive semiconductor layers; a fluorescent layer on the light emitting structure; and a light extracting structure on the fluorescent layer. The worm wheel is disposed under the worm. Finally a material including at least one particle having atomically engineered local chemical and electronic environments, characterized in that the local environments providing bulk nucleation. The frame has an open area above the cavity. According to the invention, the helical spring in the relaxed state has an outer diameter which is larger than the inner diameter of the internal tube.
