AUTOMATIC ANALYZER AND AUTOMATIC ANALYSIS METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18259810 titled 'AUTOMATIC ANALYZER AND AUTOMATIC ANALYSIS METHOD
Simplified Explanation
The abstract describes an automatic analyzer that prevents the influence of a disturbance component on a measurement result by emitting light towards a sample, changing the frequency of the drive current supplied to the light source, detecting the transmitted light through the sample, and demodulating the light detection signal to output a measurement signal.
- First light source emitting light towards a sample
- Drive circuit supplying a drive current with changing frequency to the light source
- Light receiver outputting a light detection signal based on transmitted light through the sample
- Signal processing circuit demodulating the light detection signal and outputting a measurement signal
Potential Applications
This technology could be applied in medical laboratories for analyzing blood samples, environmental monitoring for analyzing pollutants in water or air samples, and food safety testing for detecting contaminants in food products.
Problems Solved
This technology solves the problem of disturbances affecting measurement results in automatic analyzers, ensuring accurate and reliable data for analysis and testing purposes.
Benefits
The benefits of this technology include improved accuracy in measurements, reduced errors in analysis, increased efficiency in testing processes, and enhanced reliability of results.
Potential Commercial Applications
Potential commercial applications of this technology include medical diagnostic equipment, environmental monitoring devices, and food safety testing instruments.
Possible Prior Art
One possible prior art for this technology could be automatic analyzers with similar light detection and demodulation capabilities, but without the specific feature of changing the frequency of the drive current to prevent disturbances.
Unanswered Questions
How does the frequency change of the drive current prevent disturbances in the measurement results?
The frequency change of the drive current may help in filtering out noise or interference from the measurement signal, but the specific mechanism behind this process is not detailed in the abstract.
Are there any limitations to the application of this technology in different types of samples or environments?
It is not mentioned whether this technology is suitable for all types of samples or if there are specific limitations based on the characteristics of the samples or testing environments.
Original Abstract Submitted
In an automatic analyzer, an influence due to a disturbance component on a measurement result can be appropriately prevented. An automatic analyzer includes: a first light source configured to emit light toward a sample ; a drive circuit configured to supply a first drive current I whose frequency changes from f to f intermittently or continuously to the first light source ; a light receiver configured to output a light detection signal IR based on the light transmitted through the sample ; and a signal processing circuit configured to demodulate the light detection signal IR in accordance with the frequency f to f of the first drive current I and output a measurement signal VL based on a demodulation result.
