Will Smart Improvements to Child Restraints Increase Their Popularity?

In developing countries, child safety seat use remains low, which contributes to the consistently high rate of child injuries and deaths in traffic accidents. In order to protect the safety of child passengers, it is necessary to improve the public acceptance of child restraints. We improved the shortcomings of the traditional child restraints by adding some new features: 1, tightening Isofix automatically; 2, using temperature sensing, a high-temperature alarm, automatic ventilation, and cooling; 3, using pressure sensing, if the child is left alone it will set off the car alarm; 4, voice control to adjust the angle of the backrest; 5, the seat can be folded into the trunk. These functions make human-computer interaction more humane. The authors collected changes in parental acceptance of child restraints using the interview method and questionnaires. We found that acceptance increased significantly after making intelligent improvements to the child restraints. The authors used the Technology Acceptance Model to identify the key caveats influencing users' use of intelligent child restraints. Performance expectations, effort expectations, social influence, convenience, and hedonic motivation positively and significantly impacted the willingness to use intelligent child restraints, so the authors suggest that these points should be emphasized when promoting the product. The current study findings have theoretical and practical implications for smart child restraint designers, manufacturers, sellers, and government agencies. To better understand and promote child restraint, researchers and marketers can analyze how people accept child restraint based on our research model.

Quantitative Study on Road Traffic Environment Complexity under Car-Following Condition

With the development of the drive of electronic communication technology, the driving assistance system that perceives the external traffic environment has developed rapidly. However, when quantifying the complexity of the road traffic environment without fully considering the driving characteristics and subjective feelings, the false alarm rate of the driving warning system increases and affects the early warning effect. In order to more accurately quantify the complexity of the road traffic environment, we analyzed the impact of road traffic environment changes on drivers under the condition of car-following. Firstly, we selected the influencing factors of the traffic environment complexity, such as the driving operation indicators, the vehicle driving status indicators and the road environmental indicators. The weight calculation model of each influence factor is established based on the principal component analysis method. Secondly, the driver’s reaction time during car-following is used as the quantitative index of road traffic environment complexity. The quantitative model of road traffic environment complexity is constructed combined with the weight of road traffic environment complexity. Finally, the driving simulation experiment is designed to verify the complexity quantification model of the road traffic environment. The road traffic environment complexity value calculated in our study is better than the TTC, and the early-warning threshold is raised by 2–5%. The research conclusion can provide a basis for the design of the car alarm system.

An Enhanced Accident Detection and Recovery System Using MEMS Technology

Abstract This is an intention to implement an innovative solution for this problem by developing an automatic accident detection system and recovery analysis play an important role. By using this mobile (SMS) and also with the help of embedded technology we can solve this problem. An accelerometer can be used in a car alarm application; Dangerous driving can be detected with an accelerometer. The vibration sensor detects the accident. The MEMS sensor detects a rollover and alerts the driver. A major accident can be detected using accelerometer readings. According to this idea, when a car is involved in an accident, the vehicle number and contact information for the people involved are promptly recorded and will be transferred to police control room or a rescue team by using GSM MODEM. As a result, using GPS, the cops can quickly determine where the communication originated. One more advances of this modern technology were for an uncertain situation many of vehicles that have center locking system, Due this technology people faces many problem due to automatic locking system. There is no option to open the lock in the case; our work will provide a suitable solution for this so it is useful for implementing this project in useful way to reduce the human death ratio by accidents.

ОБОСНОВАНИЕ ПРИМЕНЕНИЯ ТЕПЛОВОЙ ПОДГОТОВКИ НА АВТОМОБИЛЯХ В РАЗНЫХ КЛИМАТИЧЕСКИХ ЗОНАХ

The paper presents the rationale for the feasibility of using an autonomous liquid heater for thermal preparation of the engine in different climatic zones. A comparison is made of operating costs when using an autonomous liquid heater and a car alarm with the function of maintaining the optimum temperature. Several large settlements of the Tyumen region were selected for a comparative calculation. Using climatic portals, the average number of cold days over three years was selected and the number of cold engine starts in each city was determined. The objects of the study were Toyota Land Cruiser Prado cars with different power plants: diesel and gasoline. The calculation does not consider the effect of the autonomous heater on the comfort of use and the technical condition of the vehicle, only the current fuel costs during daily operation are taken into account. In the course of the calculations, it was found that at ambient temperatures up to -150C for a gasoline car and -170C for a diesel car, the use of a pre-starting autonomous liquid heater is not economically viable. The required number of days is also determined to obtain economic benefits from the pre-heater, taking into account the cost of its installation on cars with gasoline and diesel engines. Using the results of the study, it can be concluded that not in all settlements it is advisable to install preheaters. The severity of the climate in some cities does not pose a big threat to a guaranteed cold engine start and may be limited only by using the remote engine start function built into the security system.

Automated Power Window Opening on Carbon Monoxide Detection

This paper presents an embedded system for car cabin safety. A number of sudden deaths happened due to inhaling of carbon monoxide (CO) gas inside car cabin in the past years. The designed embedded system keeps on sensing the accumulated CO gas inside the car cabin. If the value of CO exceeds the predefined threshold value and the motion sensor installed in embedded system detects the presence of any occupant inside the car cabin, a warning text message gets displayed on LCD installed in car cabin and buzzer alarm is generated. The warning text message is sent by GSM kit to occupant cell phone. After receiving response from occupant, DTMF kit generates a preset sequence number and sends a signal to the microcontroller. On receiving this signal, control unit immediately sends signals to power window control circuit of the car to open the power windows to let fresh air come in the car and as the amount of CO reaches below predefined threshold value, power windows of car are rolled up again automatically.

Responses of Eastern Gray Squirrels (Sciurus carolinensis) to Predator Calls and Their Modulation by Coat Color

Abstract In mammals, expression of certain melanocortin receptor ligands is correlated with both dark pigmentation and increased stress resistance and higher levels of aggression. Though many studies of captive and laboratory animals have explored this pleiotropic interaction, relatively few studies of animal behavior have occurred in free-living wild animals. This playback study focused on the antipredator behavior differences between melanistic and gray morphs of eastern gray squirrels (Sciurus carolinensis) in Hiram, Ohio. Vigilance, tail flagging, freezing, and escape behaviors were recorded in response to digital playback of an American robin call, a chickadee call, a car alarm, a buzzer, or one of two different red-tailed hawk calls. All squirrels exhibited increased antipredator behavior after hearing increasingly threatening stimuli. Consistent with prior findings in other species with color polymorphism, gray morphs were more likely to escape after hearing a threatening call. A growing body of ev...

The Low-Power High-Frequency Transceivers with a Received Signal Power Indicator Used in the Access Control System

The article deals with relevant issues to implement automatic disarming through the radio channel of car alarm when approaching the car. Notes that the implementation of automatic (keyless) access in standard automotive systems, using wireless communication between the owner's transponder tag and the car's transponder at a frequency of 125 kHz and a set of active antennas, requires large costs and is therefore available only in business-class cars. To implement this function in the same form at the stage of installation of additional equipment is expensive and time-consuming. As an alternative, the proposal is to use the radio car alarm. A disarming process involves two devices, namely a RFID-tag, which the owner carries around, and an alarm unit. Both the tag and the alarm unit radio channel contain transceivers, i.e. devices capable of operating both as a transmitter and as a receiver. The paper justifies that it is expedient to place the transceiver of unit on the car windshield and use a passive label responding to the request signal from the transceiver of unit. Formulates requirements for transceiver characteristics and based on the analysis of publications proves the CC2400 (Texas Instruments) transceiver selection. Analyses the possible types of antennas the manufacturer offers for the CC2500 transceiver. Estimates their using efficiency in RFID-tags through manufacturing and testing a developed batch with PCB antennas of different type. A developed proprietary antenna design, as compared to the manufacturer’s antennas, has a polarization diagram close to circular. The paper shows its experimentally estimated effectiveness. An algorithm is analysed when the distance of automatic disarming is adjusted only through the power of the transmitter of the alarm transceiver. It is noted that the algorithm does not use information about the signal from the tag to the unit. It is experimentally justified that its use of the algorithm without feedback allows us to obtain a stable automatic disarming zone. A radio-exchange algorithm between the car alarm transceiver and the tag transceiver is proposed and justified using the power indicator of the signal received from the tag. The operation and effectiveness of the proposed algorithm are tested experimentally.

Data Signal Processing Algorithms and Combined Shock, Tilt, and Motion Sensor Implementation Based on the 3-Axis MEMS -Accelerometer

In modern times of security systems, sensors are, usually, microprocessor-based devices using digital signal processing. Shock sensor, volume sensors (ultrasonic, microwave), tilt, and motion sensors belong to the smart ones. Shock sensors with sensitive elements (SE) of piezoelectric, microphone, and electromagnetic types have a number of essential drawbacks and therefore the most promising, at the moment, is the use of three-axis MEMS accelerometers as the SE. In this case, a combined shock, tilt, and motion sensor can be implemented on a single SE. Publications describing combined shock, tilt, and motion sensors do not formulate requirements for characteristics of accelerometers to be used. It is not clear enough, what a data signal is. And what the range of the measured accelerations acting on the sensor and the frequency spectrum of the signals under shock, tilt, and motion are. In this regard, a number of experiments to investigate data signal obtained from the three-axis accelerometer with different actions on the car have been conducted. Based on the experimental data the author has developed and presented the signal processing algorithms of MEMS-accelerometer ADXL-345. This accelerometer has been used in the combined shock, tilt, and motion sensor implemented for the car alarm ‘Excellent’. The paper considers algorithms of signal filtering, selecting the thresholds at which actuation of sensors occur, temperature stability of characteristics, and the algorithm to eliminate sensor false positives across the alarm zone. Gives recommendation for the technical implementation of algorithms on the PIC-microcontrollers.

The Rapid growth of technology and infrastructure has made our lives easier. The advent of technology has also increased the traffic hazards and the road accidents take place frequently which causes huge loss of life and property because of the poor emergency facilities. Our project will provide an optimum solution to this draw back. An accelerometer can be used in a car alarm application so that dangerous driving can be detected. It can be used as a crash or rollover detector of the vehicle during and after a crash. With signals from an accelerometer, a severe accident can be recognized. According to this project when a vehicle meets with an accident immediately Vibration sensor will detect the signal or if a car rolls over, and Micro electro mechanical system (MEMS) sensor will detects the signal and sends it to ARM controller. Microcontroller sends the alert message through the GSM MODEM including the location to police control room or a rescue team. So the police can immediately trace the location through the GPS MODEM, after receiving the information. Then after conforming the location necessary action will be taken. If the person meets with a small accident or if there is no serious threat to anyones life, then the alert message can be terminated by the driver by a switch provided in order to avoid wasting the valuable time of the medical rescue team. This paper is useful in detecting the accident precisely by means of both vibration sensor and Micro electro Mechanical system (MEMS) or accelerometer. As there is a scope for improvement and as a future implementation we can add a wireless webcam for capturing the images which will help in providing drivers assistance.

Design of open architecture System to reduce the likelihood of a vehicle getting stolen or carjacking

This paper is practical design and implementation of An Electronic protection system for protection from motor vehicle theft. It is a specific form of computer-based information system that complies with International safety regulations and can be used in any types of cars, ships, trains, and airplanes. Nationwide in the US in 2005, there were an estimated 1.2 million motor vehicle thefts, or approximately 416.7 motor vehicles stolen for every 100,000 inhabitants.[1] It can be added to navigation, control system for the protected vehicles. Not all protection systems are used for safety and protection but in our design we comply with both requirements. The system can control and displays information of controlled parameters like power for the fuel pump, electricity for the ignition system, audio and visual alarms or others. The designed system can prevent the operation of the engine unless the right store cod is entered also it can let the engine operate only for certain specific previously determined time, or reduce the speed of the engine at certain conditions or it can stop the engine completely in case of danger for example if the driver fell into sleep depend on PIR (Passive Infrared Piezoelectric) or IR motion sensors. It may also display additional navigation-related information, such as Sailing Directions, speed, or remains fuel. The system are power by 12 V dc supply which is available in types of vehicles, to start operation we need to enter the password for the key board, We will demonstrate the program which will is used in actual work for the system it is written in basic to the microcontroller type16F84A .We preferred to design the software using software PIC Basic for microcontroller. This Program is a window based Software and friendly user. Our design covers various methods of prevention to reduce the likelihood of a vehicle getting stolen. These include physical barriers, which make the effort of stealing the vehicle more difficult. Some of these include: Immobilizers, allowing the vehicle to start only if the right password containing the correct code is present in the stored microcontroller to give start signal for ignition. Adding to those Chances of theft can also be reduced with various deterrents, which give the impression to the thief that s/he is more likely to get caught if the vehicle is stolen. These include: Car alarm systems that are triggered if a breaking and entry into the vehicle occurs and trying to start the engine, Killswitch circuits we designed to frustrate or slow down the efforts of a determined car thief. Kill switches are often located between crucial parts of the starting system, between the battery source and the coil, or the fuel pump. A car cannot start without first flipping these killswitches to closed position. Car owners hide these killswitches in obscured areas, under the dashboard, beneath the seat, behind a chair, etc.
