Abstract

Advancement on camera technology, image processing, and signal processing algorithm is widening the usage of camera into biomedical measurement. Mostly are used for pulse rate (PR) measurement to monitor human’s heart condition. In this paper, we studied the prospect of a consumer grade RGB camera as replacement for contact-based pulse oximeter (measure pulse rate and blood saturation oxygen). However, in this study we more focus on blood saturation oxygen measurement which needs more complex principle and calculation compared to PR measurement. We use both time and frequency domain calculation to know whether one or both of them have better achievement. The results reveal the summary performance from the usage of a consumer-grade RGB camera in saturation oxygen measurement.

Abstract

Technology brought by human race has been evolving from known stone age, axe age, wood age and until we now reach the point where semiconductor or integrated circuit (IC) technology support human life. Its implicitly important to us to know, how current technology developed and what possible next technology look like. In this paper, we emphasize the quick walkthrough how our scientist and practical engineer made IC. Furthermore, a cheat sheet provided for a very basic equation we use when we made IC. Experiment on this research performed by using open source software which allow others to redo the same experiment. The outcome of this paper is well-structured introduction about IC technology and global discussion regarding next generation technology.

Abstract

machine learning and edge computing currently becomes popular technology used in any discipline. Flexibility and adapt to the problem are the main advantages of its technology. In this paper, we explain step-by-step way to make a lightweight machine learning model especially intended for embedded system application. We use open source machine learning tool called as Weka to design the model. Moreover, we performed a simple stress recognition experiment to make our own dataset for evaluation. We evaluate algorithm complexity and accuracy for different well-known classifier such as support vector machine, simple logistic and hoeffding tree.
