Abstract: Example methods and devices for blood pressure measurements are disclosed herein. The example methods include determining whether to perform blood pressure measurement on a user, and determining a blood pressure measurement mode used to perform the blood pressure measurement based on a degree of impact on a sleep status of the user. In a first measurement mode, the user needs to be prompted to adjust a blood pressure measurement posture to meet a blood pressure measurement requirement. After the user confirms that the posture is adjusted, blood pressure measurement is performed on the user. In a second measurement mode, blood pressure measurement can be performed on the user without prompting the user to adjust a blood pressure measurement posture.

Abstract: The present invention relates to a mass spectrometer system, which combines laser desorption with pulse bursts comprising a train of ultrashort pulses and electrospray ionization. The pulse separation between individual pulses within the pulse burst is selected such that transient phenomena on an irradiated sample do not fully relax between individual pulses. Pulses with pulse widths ranging from fs to sub ns are conveniently implemented. The pulse widths can be selected to allow for multi-photon excitation of a sample while at the same time minimizing heat accumulation in a sample. Low cost laser systems such as fiber lasers can be configured to generate appropriate pulse bursts. The technique is suitable for mass spectrometry imaging with high spatial resolution. The laser system can serve as an electronic clock to which the whole mass spectrometry system or mass spectrometry imaging system is synchronized.
