Abstract: In an example method, a mobile device obtains a signal indicating an acceleration measured by a sensor over a time period. The mobile device determines an impact experienced by the user based on the signal. The mobile device also determines, based on the signal, one or more first motion characteristics of the user during a time prior to the impact, and one or more second motion characteristics of the user during a time after the impact. The mobile device determines that the user has fallen based on the impact, the one or more first motion characteristics of the user, and the one or more second motion characteristics of the user, and in response, generates a notification indicating that the user has fallen.

Abstract: The present disclosure relates to devices, apparatus and methods of improving the accuracy of image-based assay, that uses imaging system having uncertainties or deviations (imperfection) compared with an ideal imaging system. One aspect of the present invention is to add the monitoring marks on the sample holder, with at least one of their geometric and/optical properties of the monitoring marks under predetermined and known, and taking images of the sample with the monitoring marks, and train a machine learning model using the images with the monitoring mark.

Abstract: The present invention relates to a composition analysis technology of ultramicro-volume liquid by laser ablation plasma mass spectrometry. Using a pipette gun to extract the liquid to be detected in a low-temperature environment, dropping the liquid into a dropping pit in a dropping plate, the liquid level is slightly higher than an overflow table in the dropping plate; dropping different liquid samples into different dropping pits by the same method; gradually covering the dropping pit with an analysis film having an area 1.5 times larger than that of the dropping plate from one side of the dropping plate, tightly adhering the thin film onto the dropping plate by using a transparent adhesive tape, the thin film is in close contact with the liquid level; placing the dropping plate covered by the thin film in a LA-ICPMS universal solid sample chamber, and then setting parameters for ablation.

Abstract: A method for coating a substrate surface where different types of powers are applied to the substrate and different targets. The method involves the formation of a layered structure in the coating where a metal layer is first formed, on top of which is an intermediate layer followed by a top functional layer which is chromium oxide composite. One of the power types is radio frequency power, used particularly for enhancing the efficiency of ionisation and decomposition of the reactive gases in the system. Another type of power, current that is controlled in a pulsed manner, is applied to substrate to improve the alignment of the deposited ions and atoms on the coating surface.
