Title: New method for measuring vertical profiles of multiple atmospheric parameters in real time by means of aerostat carrying
Inventor: SHIYONG SHAO
IPC: G01D21/02
Filed: 2017-04-28
Abstract: A new method for obtaining vertical profiles of multiple atmospheric parameters at the same time. Measurement devices based on various principles and capable of measuring multiple parameters at the same time are fixed on a cable of an aerostat at a specified distance interval, and each measurement device finishes measurement of atmospheric parameters at the height and transmits data to a ground collection device in real time, so as to realise synchronous acquisition of profiles, measured in real time, of multiple atmospheric parameters. The profile data has no prerequisite of assumption, and can provide calibration data for a ground remote sensing device, such as a radar, which performs measurement at the same site, while providing conventional meteorological parameters and atmospheric pollution data for meteorological and environmental governance departments.

Title: Method and system for measuring and displaying biosignal data to a wearer of a wearable article
Inventor: CONNOR DAVID DRISCOLL
IPC: A61B5/364
Filed: 2021-11-17
Abstract: An electrocardiogram (ECG) output A is corrected for anomalous heartbeats 1 by obtaining a series of heart rate values, determining when the rate of change of the heart rate values exceeds a threshold, and identifying a selected heartbeat as anomalous if the threshold is exceeded. The threshold is selected based on a likely signal-to-noise ratio of the ECG output, for example based on obtained activity level information of a user. One or more correcting steps X, X’’ are sequentially applied to the region around the anomalous heart beat. The correcting steps may include one or more of removing, inserting or moving the position of a selected heartbeat. The rate of change of heartrate values may be determined for each correcting step, and the correcting step corresponding to the lowest rate of change is selected as a permanent correction for that region of the ECG output. An embodiment includes a wearable article with a sensor arrangement to obtain the ECG signal.
