Patent MY-174037-A (MY)
Title: Waveform estimation device and waveform estimation method
Inventor: YOKOYAMA YOSHIAKI
Filed: 2014-12-19
Abstract: A waveform estimation device includes: tracking filter processing units (11) and (12) that execute tracking filter processing on observation values using tracking filters having different drive noises; and a filter output selection unit ( 14) that selects a regular waveform component predicted by the tracking filter processing unit ( 11 ), in an irregular section, and selects a regular waveform component predicted by the tracking filter processing unit (12), in a regular section. A residual processing unit (16) calculates a residual between observation values extracted by an observation value extraction unit ( 1 ), and a regular waveform component selected by the filter output selection unit (14). An irregular waveform detection unit (17) determines whether the residual is an irregular waveform component.     Figure 1.

Title: Method and system for applying superimposed time-varying frequency electromagnetic wave to target object or target region
Inventor: CHEW HWEE HONG
IPC: C02F1/32
Filed: 2015-07-29
Abstract: The invention relates to a system (100) for applying a superimposed time-varying frequency electromagnetic wave to a target object or a target region that is formed by the target object and a medium (130) surrounding the target object, comprising a device (110) for generating a superimposed time-varying frequency electromagnetic wave where the time-varying AC wave is riding on the predefined DC bias voltage. When applied to the object or region, the superimposed time- varying frequency electromagnetic wave is able to induce a flow of ionic current having a DC component traveling in a pulsating and time-varying manner in the target object and/or in the medium (130) and effect induced vibration of electrons and molecules of the target object and the medium (130). The invention also relates to a method applying a superimposed time-varying frequency electromagnetic wave to a target object or a target region. The method and the system (100) of the invention significantly reduce the capital cost and require very low energy, with the environmentally friendly final products, and are able to result in various treatment effects simultaneously.

Title: System and method for heart rate estimation
Inventor: MUKHOPADHYAY SHALINI
IPC: A61B5/024
Filed: 2018-01-22
Abstract: SYSTEM AND METHOD FOR HEART RATE ESTIMATION Techniques for heart rate estimation are disclosed. In an embodiment, synchronized photoplethysmograph (PPG) and -axis acceleration signals are received. Further, the PPG and acceleration signals are partitioned into windows. Furthermore, it is determined whether motion is present in a window of the acceleration signal. Moreover, Fourier transform is performed on the signals to obtain power spectra of the signals in the window when there is motion. Also, it is determined whether a peak of the acceleration signal is present in a range around first highest PPG peak. Further, it is determined whether the peak of the acceleration signal affects heart rate of the user when the peak of the acceleration signal is in the range around the highest PPG peak. The heart rate of the user in the window is then estimated using second highest PPG peak when the peak of the acceleration signal affects heart rate of the user. Fig.2A 23

Abstract: This invention is related to the field of agriculture, namely to the processing of wet colza seeds after harvesting. The method includes seed feeding with a belt conveyer into an electric field and its fractioning according to humidity. The speed of the conveyer is 1 m/s. The strength (E) of the electrical field is changed in the range 1 to 2.4 kV/cm according to the initial humidity of the seed (W). Output to a wet seed fraction B is changed by setting the strength of the electrical field according to the following equation: B=46.52-38.31E+0.33W-0.77EW+10.08E<2>+0.08W<2>. While the seeds are fractioned at the set electrical field strength according to the desired output, the humidity difference between the fractions Δ W theoretically is expressed by formula: Δ W=8.4-1.32E+0.2W+0.03EW+0.27E<2>-0.01W<2>. The humidity of the seed being processed is no less than 12 %.
