"Alat ini berfungsi sebagai pedometer untuk mendeteksi aktivitas gerakan tubuh seperti berdiri, duduk, tidur telentang, tidur tengkurap, dan menghitung jumlah langkah serta konsumsi energi dalam melakukan pergerakan tersebut. Pengiriman data secara wireless menggunakan bluetooth witilt 2.5.Pengukuran jumlah langkah dilakukan dengan menggunakan metode peak detection sedangkan pengukuran penggunaan energi dilakukan berdasarkan jumlah langkah yang terdeteksi dengan menggunakan nilai metabolic equivalent (MET) sebesar 3,3 untuk aktivitas berjalan dengan langkah sedang pada permukaan datar.Respons MMA7260Q terhadap perubahan tilt juga diamati dan didapat hasil korelasi linier yang memuaskan antara nilai tilt terukur dengan kemiringan sensor pada ketiga kanal sumbu (R2  1). Pada pengujian pedometer juga diperoleh hasil yang memuaskan. Namun untuk dapat merancang monitor portabel aktivitas pasien dengan akurasi tinggi masih diperlukan studi lebih lanjut menggunakan mikrokontroler.

This device?s main role is as a pedometer to detect body?s activities during any movement such sitting, standing, laying straight-up, laying facing down-ward as well as counting the number of steps taken to include the energy consumed in doing so. The data transfer is performed through wireless mode using Bluetooth witilt 2.5.

Peak detection method will be used in determining the number of steps taken whereas the energy consumed for the steps shall be measured by the number of steps detected with the measured metabolic equivalent (MET) with the nominal value of 3.3 for walking movement under the condition of medium pace on a flat surface.

Any responds of MMA 7260Q towards any variation occurred to the tilt will be closely observed which result a linear correlation which may satisfy the value of measured tilt value with the sensor slope of three canal axis (R2  1 ). A satisfactorily result was also obtained from the pedometer testing. However, further and more detail study using microcontroller may need to be conducted in order to be able to design a portable monitor for patient?s activity."

"ABSTRAKIn this paper we show a simple and effective method for regularizing the Coulomb potential for numerical calculations of quantum mechanical problems, such as, for example, the solution of the Schrodinger equation, the expansion of charge density and others. The introduction explains why the regularization of the Coulomb potential is important. In the second part, the regularization method itself as well as its advantages and disadvantages will be described in detail. The third part demonstrates some numerical calculations for the Sulfur plus Hydrogen system using the proposed method. In the final part, the obtained results are summed up."
