A multi-function health detection instrument is developed, which is mainly composed of an arm9 S3C2440 embedded system, a physiological parameter acquisition board, Bluetooth communication module, GSM module, and other additional modules. This instrument can be applied to detect the signals, such as ECG, blood pressure, body temperature, heart rate, SP02, and blood sugar in the home at any time. Also...
In this paper, the extraction for noised saturated sinusoidal signal is proposed for the electro-magnetic coupling sensing system. The method is based on the Least Squares fitting Method to extract the signal amplitude and phase from the saturated sinusoidal signal. According to the extracted amplitude and phase, we can get a sinusoidal signal and remove the sample with lager error by comparing it...
As the capsule endoscope lens will produce geometric distortion, while there is an angle and a corner between the camera image plane and the plane of scene, so the images of capsule endoscope get nonlinear geometric distortion. Before the capsule endoscope images are used to accurately analysis, we should eliminate these distortions. Typically, the correction uses a calibration pattern, which can...
In applications of permanent magnet, the calculation for magnetic flux intensity is of primary importance. The magnetic dipole is simple mathematic model which is used frequently. However, it is required that the evaluation points are far from the magnet; otherwise, the measured data is wrong. An approach of calculating the magnetic flux intensities at those points which are very close to the magnet...
The basic content to instruct graduation design (thesis) through co-operative education of university and corporation is to develop and improve the overall quality of students' integrated capabilities and focused on employment competitive ability. This pattern fully uses school and society that are two kinds of different education environments and resources as well as in talented persons raising aspect...
This paper specifically describes the design of hardware and software of a digital pulse oximeter based on ARM core embedded system and light-frequency converter. In this study, a light-frequency converter instead of a photodiode was adopted to receive the light transmitting, which greatly simplified the design of hardware. Besides, traditional methods of calculate frequency of rectangle signal were...
