Abstract: A wake-up device, used for awaking a user in a nap or a short-term sleep, includes an electroencephalogram (EEG) sensor, a processing module and a wake-up module. The EEG sensor is disposed on the user's head for sensing an EEG signal from the user. The processing module is coupled with the EEG sensor, and receives and processes the EEG signal. If the user is determined in the sleep stage 2 according to the EEG signal, the processing module outputs a wake-up signal. The wake-up module is coupled to the processing module for receiving the wake-up signal, and awakes the user according to the wake-up signal.

Abstract: Disclosed herein is a novel process for the manufacture of N(mercaptomethyl) phthalimide S-(O,O-dimethyl phosphorodithioate) wherein increased production in a series of given size reaction vessels is achieved, which process comprises operating at a higher temperature and at a higher product-to-solvent ratio than hereinbefore practiced.
