Abstract: In the year 2016 alone, more than 1.35 billion smartphones were manufactured globally. These smartphones contain up to 60 different chemical elements and the summarized metal weight of the 2016 production may have well exceeded 50,000 metric tons. At present, most elements contained in this very complex “mixture” represented by a smartphone have recycling rates well below 50%, and the recycling rates of rare earths, indium, tantalum or gallium are even below 1%. The major challenge of mobile phone recycling is the complex composition of the devices made of many individual components – and the lack of transparent information as to the composition of these components. This is aggravated by the fact that many elements occur in traces only and / or are located in highly complex material composites. To enable more effective recycling of mobile phones, it is thus imperative to characterize the constituent components, the presence of elements in it, as well as their behavior during comminution. In a pilot study, a Nokia mobile phone Model 5228 Type RM-625, crushed with a granulator UG300, was examined by Mineral Liberation Analysis. The analysis of three particle size fractions of the comminuted material was carried out in an automated measurement mode with a grid of energy-dispersive X-ray spectra. A total of 130 different phases were detected during this analysis. More than 100 of these phases occur at levels <1% by weight. This strongly illustrates the very complex composition of smartphones. A comparison of the modal content of the three particle size fractions showed good liberation of certain components and an enrichment of some components in specific fractions. These observations reveal the potential to successfully separate different technical components from one another with the goal to increase the resource efficiency of the recycling process.

Abstract: In this paper the NutriScale-Algorithm is described. NutriScale interprets meals and calculates health related scores. It is based on a food pyramid, which was created by the German Nutrition Society according to existing food related and evidence based medical guidelines. Furthermore various food related mobile phone apps and professional desktop applications were analyzed to figure out, what functionality and data sources are appropriate to create such a promising key figure for food selection like NutriScale.

Abstract: The present study deals with the development of remote control system based on the Global System for Mobile Communication (GSM) technology for switching the low voltage AC power supply system at residential consumer. Function of this system is to disconnect and reconnect the electricity supply to consumers. The introduction of the GSM technology and particularly the use of hand-held mobile phones has brought the innovative distance communication to remote locations. This utilization of this technology for the remote control of systems and appliances will make life easier, safe and quick from anywhere. GSM module was used for receiving short message service (SMS) from user’s mobile phone that automatically enable the controller to take any further action such as to switch on and off the consumer load at the incoming power supply. The system was integrated with microcontroller and GSM network interface using assembly language. AVR Studio 4 software was utilized to accomplish the integration. The system is activated when user sends the SMS to GSM controller circuit at electric meter consumption panel board. Upon receiving the SMS command, the microcontroller unit then automatically controls the incoming power supply by switching on or off the device according to the user command. In other words, the developed system reads message from the mobile phone and responds to control the devices according to the received message. The system can also give feedback to the user to inform the status of switching operation if such command is received.

Abstract: Health-care situations in present have pass to be a technology-based. In addition to handheld devices like a mobile phone and their habit has risen abundant in current period. This research presents the design and implementation of application on IPhone for patient health-care. A physique zone network is a WIFI of biomedical sensors that are around to a man body. The aim of wireless body area network is to assist the progress of continuous recording and monitoring of a person’s health circumstances and transfer it over a long-distance exchanging network. The parameters sensed by the distinctive devices are to be moved onto a mobile phone or a tablet using wireless network. This information is then assembled, stored, check for threshold and then sent to the doctor for constant monitoring of the patient’s health condition. The doctor can thus access the patient’s health status on the go and this will help the patient to get suddenly attention in life-threatening situations.

Abstract: As the mobile with large screen easily fall damage, in this paper, a finite element model of the mobile phone was built and drop simulation analysis based on ANSYS/LS-DYNA software. The impact force effects on the phone shell, LCD, touch and battery components were studied. The corresponding stress and strain distribution and the acceleration and dynamic characteristics were solved and the dangerous area of the mobile phone was found. Finally the corresponding optimization proposal was put forward. Provide reference for the study and optimization design of structure strength for this type of products.

Abstract: As the development of the Internet of things and the application of M2M, smarter campus ushers in new era. This paper proposes the smarter campus system architecture based on the mobile phone M2M. It consists of four levels, two systems, two platforms and N APP. And points out the key technologies of this system construction: sensing and communication, storage and security and system integration and application services. aims to explore a kind of mode of digital campus as "if we have mobile phone all in one, we can walk through the campus", so as to realize the ubiquitous network study, the integration innovation of scientific research, transparent and efficient school management, rich and colorful campus culture, convenient and thoughtful campus life.

Abstract: Price forecasting based on training step is discussed in this paper. The purpose of forecasting is obtaining suitable commodity price forecasting model. This experiment uses a whole year price for ten type's mobile phone .The price data is extracted from http://www.jd.com/. The whole year data is used as the original data to improve Least Squares Support Vector Machine (LS-SVM) model based on the training step. By researching this forecasting method, the experiments are carried out under different training steps, different types cell phones depending on the accuracy rata. With the growth of the training step, the precision of the LS-SVM model cuts down obviously. The research can help consumers obtain the better purchase decision-making when they buy cell phones, provide cell-phone distributors with certain reference.

Abstract: In this paper, the purpose is to develop a Short Message Service (SMS) system that can aid the ALS patients to control a mobile phone to send a message by using of the steady state visually evoked potentials (SSVEP) brain computer interface (BCI) to a person who can help him/her. The EEG signals may be detected by electrodes and signal extracting chip. Then these signal can be transmitted to the mobile platforms by using of Bluetooth interface. Finally, the message and phone number can be selected in accordance with the components in frequency domain transferred from time domain. The experimental results had shown that the proposed system can easily send a message from a mobile phone to another.

Abstract: A small-size printed antenna is proposed for the application of mobile phones. The antennacomprisesan outer strip, an inner strip, and a common section.It not only occupies a compact area of 25 × 20 mm² butalsosupports two wide bandswithinthe resonantmodes. Prototypes of the antenna had been constructed and experimentally verified. The measured results of the antenna show the bandwidth cover the existing service bands of GSM/DCS/PCS/UMTS within 6 dB return loss specification, and also have good radiation patterns and antenna gains.This antenna is well suitable to be used for mobile phone application.
