INTRODUCTION Seat belt use reduces the risk of injuries and fatalities among motor vehicle occupants in a crash, but belt use in rear seating positions is consistently lower than front seating positions. Knowledge is limited concerning factors associated with seat belt use among adult rear seat passengers. METHODS Data from the 2012 ConsumerStyles survey were used to calculate weighted percen...

This paper presents an obstacle avoidance module dedicated to non-holonomic wheeled mobile robots. Chained system theory and deformable virtual zone principle are coupled to design an original framework based on path following formalism. The proposed strategy allows to correct the control output provided by a navigation module to preserve the robot security while assuring the navigation task. F...

This paper presents the design and testing of multiple infrared range detectors arranged in a two‐ dimensional (2D) array. The proposed system can collect the sparse three‐dimensional (3D) data of objects and surroundings for robotics applications. Three kinds of tasks are considered using the system: detecting obstacles that lie ahead of a mobile robot, sensin...

A laboratory study of posture and belt fit was conducted with 46 men and 51 women, 61% of whom were age 60 years or older and 32% age 70 years or older. In addition, 28% of the 97 participants were obese, defined as body mass index ≥ 30 kg/m^2. A mockup of a passenger vehicle driver's station was created and five belt anchorage configurations were produced by moving the buckle, outboard-upper (...

Under the background of Internet of Things, the information perception and acquisition is the premise of implementation in wide fields. IoT gateway plays important role as a belt between perception layer and network layer. This paper analyzes the key problems in mobile information acquisition system based on IoT and designs the whole frames of system. Then it provides an implementation scheme i...

This paper describes the design and development of a sensor based navigation system which makes it possible for a non-holonomous mobile robot to avoid obstacles using information on its environment picked up by a belt of ultrasonic sensors. To control the robot no preliminary information regarding its environment is required, the robot adapts to them through the information gathered on the spot...

OBJECTIVE Enhanced seat belt reminders in automobiles have been shown to increase belt use rates by approximately 3 percentage points. The objective of this study was to estimate the effect of enhanced seat belt reminders on driver fatality risk. METHOD Data included all passenger vehicle driver deaths and vehicle registration counts in the United States for calendar years 2000-2007. Driver f...

BACKGROUND The effects of seat belt laws and public education campaigns on seat belt use are assessed on the basis of observational or self-reported data on seat belt use. Previous studies focusing on front seat occupants have shown that self-reports indicate a greater seat belt usage than observational findings. Whether this over-reporting in self reports applies to rear seat belt usage, and t...
