Intelligent Drivable Area Detection System Using Camera and Lidar Sensor for Autonomous Vehicle
No full textRoad detection is the most primary and important task for any autonomous vehicles. Nowadays, most of the cars available in the market have camera sensors which assist the drivers for safe driving. Therefore, we propose a sensor fusion method by utilizing LiDAR and Camera sensor together to develop a robust drivable road detection system. In this paper, the edge detection and color based segmentation techniques has been used to generate the binary image of lanes from camera sensor images. Then the line models is fitted on the generated binary image using RANSAC algorithm to find the lane marking. But there are many roads in urban area where only one side lane marks are present and sometimes no lane marking at all. In such places, the drivable road detection system wouldn\u27t be able to perform well and doesn\u27t know its boundary for the vehicle to drive. The sensor fused method proposed in this paper utilizes the LiDAR sensor information along with camera images to know its trajectory for safe travel. The algorithm works very well in different road scenarios in an urban area where the road has two lane marks, one side lane with other side curb and finally on both side curbs. The proposed method is tested with two different datasets. The overall results show that the proposed algorithm performs robustly well and the system is able to identify its drivable region accurately
Interactive Serious Game for Shoulder Rehabilitation Based on Real-Time Hand Tracking
No full textBACKGROUND: Virtual reality is becoming popular in the rehabilitation field thanks to the several advantages it can offer to patients and physicians. Indeed, serious games can: motivate and engage the patient; offer different levels of challenge and difficulty based on the patient baseline, and integrate objective measures of the patient’s performance during each rehabilitation session. OBJECTIVE: We designed and implemented a serious game for shoulder rehabilitation based on real-time hand tracking. The aim was to maintain the medical benefits of traditional rehabilitation, while reducing human resources and costs and facilitating active patient participation. METHODS: Our software application provides the user with a shoulder horizontal adduction exercise. This exercise takes place in a 2D interactive game environment, controlled by hand movements on a desk pad. The hardware includes a standard desktop computer and screen, and the Leap Motion Controller: a hand tracking system. Changing the desk pad material allows the physiotherapist to vary the friction between the user hand and the supporting surface. RESULTS: Fourteen healthy volunteers and six rehabilitation experts tested our serious game. The results showed that the application is attractive, ergonomic and clinically useful. CONCLUSION: Despite promising results, clinical validation is necessary to demonstrate the efficacy of the serious game
Injury metrics are altered in spica-casted versus non-casted child ATDs in side-impact collisions with door intrusion
No full textObjective: There is little data defining safe transport protocols for spica-casted children. A single earlier study demonstrated the presence of a body cast alters kinematics and injury metrics during simulated side-impact crashes. Since then, the National Highway Transportation Safety Administration (NHTSA) proposed a new side-impact test protocol for evaluating child restraints. This test is more severe than the earlier tests, as it simulates an impact with a door intruding into the occupant space. As no currently available child restraint system (CRS) able to accommodate a spica-casted child has been evaluated using these updated testing criteria, the objective of this study was to evaluate current restraint options in simulated side-impact collisions using an anthropomorphic test device (ATD) modeled after a 3-year-old. Methods: Four commercially available CRSs able to accommodate a spica-casted Q3s side-impact ATD were selected for testing. Side-impact testing was performed using casted and uncasted ATDs in compliance with the NHTSA proposed side-impact test. High-speed photography and ATD instrumentation were used to measure selected injury criteria. Results: HIC15 values were highest in CRSs with less robust side wings, such as the Merritt WallenburgTM (HIC15 = 1,373), which allow for the occupant to interact with the intruding door panel. Head contact with the door panel was found to correspond with high resultant neck peak force. Pelvic acceleration magnitudes were greatest for the uncasted tests. Casted tests with a CRS that included an armrest were associated with greater torso rotation in the frontal plane with the left shoulder moving toward the door panel. Conclusions: The presence of a spica cast alters injury metrics in side-impact testing. Spica specific child safety seats are not yet optimized for side-impact with door intrusion. This is due to a lack of adequate side cushion wings, which may place both casted and uncasted occupants at increased likelihood for injury through head contact with an intruding door. Additional work is needed to improve the safety of CRSs for both casted and uncasted children in side-impact collisions
Factors influencing side air curtain deployment in rollover motor vehicle accidents
No full textObjective: Recent changes in FMVSS have led to the utilization of side air curtains to provide occupant retention during rollover events. However, the safety advantage provided by the air curtains relies on the vehicle system’s ability to detect the rollover event and deploy the curtains. The purpose of this study is to identify crash and vehicle characteristics in motor vehicle rollovers that influence side air curtain deployment and occupant outcomes. The current study aims to improve the understanding of rollover events and inspire more robust air curtain deployment strategies. Methods: Study data were extracted from rollover cases documented in the NASS-CDS data set from 2011 to 2015. Vehicle model years of 2011 or later with side air curtains installed were examined. The presence of a rollover sensor in each vehicle was determined from vehicle content data available on the Insurance Institute for Highway Safety’s crash rating website. The resulting data set contained 14,003 weighted cases of rollover accidents in which the side air curtain did not deploy (40 raw count) and 23,178 cases of deployment (80 raw count). Results: Several crash event and vehicle characteristics were similar for the nondeployed and deployed groups, including number of quarter turns, primary location of damage, initiating event for the rollover, and vehicle model year. However, the nondeployed group included significantly more passenger vehicle body types (vs. SUV or truck) and had a significantly lower rate of rollover sensor presence. Presence of a rollover sensor increased the odds air curtain deployment by a factor of 36.5 (95% confidence interval [CI], 5.06–265). Cases in which both side air curtains deployed resulted in a higher frequency of injured occupants (Maximum Abbreviated Injury Scale [MAIS] ≥ 3). However, rollover events resulting in these injuries were also associated with higher rates of impact with another object or vehicle and damage to the roof of the vehicle, suggesting a higher energy event. Conclusions: Nondeployment of the side curtain airbags in rollovers occurred more frequently in vehicles without dedicated rollover sensors, which were most frequently passenger vehicles
Frontal Crash Injury Metrics are Below Mandated Limits for a Spica Casted Child Dummy in Currently Available Restraints
No full textBackground: There is a paucity of data defining safe transport protocols for children treated with hip spica casting. Although restraint devices for casted children are available, all federally mandated testing uses a noncasted anthropomorphic test device (ATD or crash dummy). The purpose of this study was to evaluate current restraint options in simulated frontal crash testing using a casted pediatric ATD to determine injury risk to the head, cervical spine, chest, and pelvis. Methods: Using a 3-year-old ATD, dynamic crash sled tests simulating frontal crash were performed in accordance with government safety standards. The ATD was casted in a double-leg spica and the following restraint devices were tested: a seat designed for spica casted children, a restraint vest-harness, a traditional booster seat, and 2 traditional forward-facing car seats. Results: Although the presence of the cast increased many of the injury metrics measured, all seats passed current federal guidelines for the head and chest. No single seat performed best in all metrics. The greatest magnitude of neck loading and second-highest head injury criterion values were observed for the booster seat. The vest-harness produced the highest head injury criterion and the chest compression exceeded proposed federal limits. Conclusions: The results suggest safe transport in commercially available seats is possible with the child properly restrained in a correctly fitting seat. However, parents should not assume a child restraint system is appropriate for use just based on fit as, for example, seats with harnesses outperformed an easy to fit booster seat. Clinical relevance: Each child and the position of the child\u27s cast are unique and discharge planning involves consideration of safe transportation. Although this study suggests several seats used to transport spica casted children pass the federal head and chest injury prevention requirements, it is important to recognize that some children may still require emergency vehicle transport
Modèles de files d’attente dans les services – approche analytique et de simulation (in French)
No full textLes modèles de files d’attente jouent un rôle significatif dans de nombreuses professions. Dans ce chapitre, nous nous concentrerons sur quelques modèles de files d’attente choisis qui sont utiles dans les secteurs de services. Bien que la littérature sur les modèles de files d’attente soit vaste et pleine d’applications diverses, il est nécessaire d’accroître le nombre de modèles dont les résultats sont utiles et aptes à la mise en œuvre. Dans ce chapitre, nous utiliserons à la fois des approches analytique et de simulation pour traiter quelques modèles choisis qui sont utiles dans la pratique ainsi que pour attirer l’attention sur le rôle significatif joué par les arrivées corrélées. Les arrivées corrélées apparaissent naturellement dans les secteurs de services en raison du fait que les clients/tâches arrivent de différentes sources. Nous signalons également certaines observations intéressantes basées sur les modèles analytiques de certains modèles de files d’attente bien connus. Il nous semble que certains de ceux-ci, en particulier ceux traitant de la période d’occupation et des fonctions de distribution des temps de séjour, ne sont pas signalés dans la littérature et sont très utiles pour la prise de décisions par l’encadrement dans les secteurs de services
