A Driver, Vehicle and Road Safety System Using Smartphones

Gozick, Brandon 05 1900 (has links)
As vehicle manufacturers continue to increase their emphasis on safety with advanced driver assistance systems (ADAS), I propose a ubiquitous device that is able to analyze and advise on safety conditions. Mobile smartphones are increasing in popularity among younger generations with an estimated 64% of 25-34 year olds already using one in their daily lives. with over 10 million car accidents reported in the United States each year, car manufacturers have shifted their focus of a passive approach (airbags) to more active by adding features associated with ADAS (lane departure warnings). However, vehicles manufactured with these sensors are not economically priced while older vehicles might only have passive safety features. Given its accessibility and portability, I target a mobile smartphone as a device to compliment ADAS that can bring a driver assist to any vehicle without regards for any on-vehicle communication system requirements. I use the 3-axis accelerometer of multiple Android based smartphone to record and analyze various safety factors which can influence a driver while operating a vehicle. These influences with respect to the driver, vehicle and road are lane change maneuvers, vehicular comfort and road conditions. Each factor could potentially be hazardous to the health of the driver, neighboring public, and automobile and is therefore analyzed thoroughly achieving 85.60% and 89.89% classification accuracy for identifying road anomalies and lane changes, respectively. Effective use of this data can educate a potentially dangerous driver on how to operate a vehicle safely and efficiently. with real time analysis and auditory alerts of these factors, I hope to increase a driver's overall awareness to maximize safety.

In vitro effect of 900 MHz GSM radiation on mitochondrial membrane potential and motility of human spermatozoa

Falzone,N, Huyser, C, le Roux Fourie, F, Toivo, T, Leszczynskid, D, Franken, DR January 2008 (has links)
Ejaculated, density purified, human spermatozoa were exposed to 900 MHz GSM mobile phone radiation at two specific absorption rate levels (SAR 2.0 and 5.7 W/kg) and examined at various time points post exposure. Change in sperm mitochondrial membrane potential was analyzed using flow cytometry. Sperm motility was determined by computer assisted sperm analysis (CASA). There was no effect of 900MHz GSM radiation on mitochondrial membrane potential. This was also the case for all kinematic parameters assessed at SAR of 2.0 W/kg. However, two kinematic parameters (VSL and BCF) were statistically significantly altered after the exposure at SAR 5.7 W/kg. Effects seen cannot be ascribed to heating, as the temperature did not increase by more than 0.3ºC. A thorough investigation at lower SAR levels is required to determine the extent of the influence of RF-EMF on human sperm motility.

InVitro effect of pulsed 900MHz GSMradiation on mitochondrial membrane potential and motility of human spermatozoa

Falzone, N, Huyser, NC, Fourie, F, Toivo, T, Leszczynski, D, Franken, D January 2007 (has links)
Abstract Ejaculated, density purified, human spermatozoa were exposed to pulsed 900 MHz GSM mobile phone radiation at two specific absorption rate levels (SAR 2.0 and 5.7 W/kg) and compared with controls over time. Change in sperm mitochondrial membrane potential was analysed using flow cytometry. Sperm motility was determined by computer assisted sperm analysis (CASA). There was no effect of pulsed 900 MHz GSM radiation on mitochondrial membrane potential. This was also the case for all kinematic parameters assessed at a SAR of 2.0 W/kg. However, over time, the two kinematic parameters straight line velocity (VSL) and beat-cross frequency (BCF) were significantly impaired (P<0.05) after the exposure at SAR 5.7 W/kg and no exposure by time interaction was present. This result should not be ascribed to thermal effects, due to the cooling methods employed in the RF chamber and temperature control within the incubator.

MindMe is an aid for people with cognitive memory impairments. The aid is completely new and has been developed within this bachelor thesis, no product of this nature could be found on the market before. The idea came from Niclas Jarhäll, CEO of Mutual Benefits. Mutual Benefits were also partners in the project. The project was carried out by us in cooperation with Bachelor of Science in Innovation Engineering students Malin Albertsson and Victoria Hedman at Halmstad university. The aid consists of a mobile phone and a number of tags. The goal was for the mobile phone and tag to set of their alarms when they get a certain distance apart. It is the technical part of the project that will be discussed in this paper and it was divided in two parts, prototype development and software for the mobile phone. The project resulted in a prototype and an application for the mobile phone. The prototype and mobile phone set of their alarms when they come to far apart. The user has the option to change settings in the mobile phone application that affects both phone and tag and to add/remove tags. Both application and tag meet the requirements set in the technical specification.

The Impact of Consumer Demographic and Lifestyle Have on Purchasing Behavior of Mobile Phone

Chen, Ruei-Ling 18 June 2004 (has links)
Since Ministry of Transportation and Communication of the DGT put ¡§liberalization of telecommunications¡¨ into practice in 1997, the development of the mobile phone industry has been 7 years. The sales volume is affected by brand, function, specification, and service of system proprietor. Moreover, the available distribution channel and the execellent after-sales service have played an important role in it. In other words, according to the replacement of mobile phone, the influence of distribution channel is more important than before. Because the real channel is the biggest part of the mobile phone industry, this study wants to research demographic and lifestyle of consumers in this field. This study adopted the research of questionnaire as study method. The target of this study is consumers who have purchased mobile phone in Kaohsiung area, and the field of this study was concentrated on demographic and lifestyle of consumer behavior. The valid questionnaire volum is 551. This study used SPPS software to access factor analysis and cluster analysis to get the lifestyle data of consumers, and then it used Chi-square test to examine the influence between the demographic and lifestyle of consumers and consumer behavior. If the examination is remarkable, it would go a step further to show the distribution of sample frequencies. By this way, we would know where the difference is.According to this study result, it shows that different gender, years, occupation, and disposable income would have the remarkable difference with consumer behavior. It meant that the consumer characteristics had influenced the purchasing behavior of mobile phone. Therefore, the distribution channel should consinder more about consumer characterstics to decide its strategy. Moreover, different lifestyle would have an impact on purchasing price and choice of purchasing place. It meant that distribution channel could aim the distinguishing feature of different group to choose unique product and business modle. It would help to satisfy the need of different group and to create distinctive position of market.

Investigation on use of Communication media of Retailers¢wfor example mobile phone

Lin, Shu-Chen 18 August 2005 (has links)
Communication plays a very important role in an organization. An exchange of information and knowledge maintains a normal operation of an organization. In addition, the establishment of co-understanding is necissary for the organization members to achieve the common goals of the organization. Communication happens when a message sender transmits information to a message receiver through the ¡§communication media.¡¨ There are two forms of communication; one is verbal and another is non-verbal or called wordless. Verbal communication includes face-to-face conversation, telephone contact and written correspondence. As to non-verbal communication, it includes physical gesture, facial expression, and the action of hand or eye that transmits messages. According to the researches, different communication media have different information capacities. To achieve the best performance, we should choose the communication media with the most match capacities and message ambiguous. Highly rich media is applied to highly complicated task, while less rich media is applied to simple and routine task. Therefore, it is important to study to the effectiveness of communication. Employees of Retail business heavily uses mobile phone as the communication media. According to the media richness theory and the social influence model, this researcy performs a survey study. The research results reveal that there is no significant differences over the ambiguous of task, media richness, usefulness, media symbolic meanings and situational factors among the department stores and supermarket of different channels. Therefore, mobile phone application is regarded as a good communication tool in the retail business. It is suggested that an organization should consider replacing or matching the existing communication tool to achieve the most effective communication.
