More and more elderly problems come to our life and the elderly health care become more important. Elderly people with lower extremities weakness usually use walkers to assist in walking. Although the commercial standard walkers (N-type) can improve elderly people's walking ability, users sometimes take risk of falling when using the standard walkers to perform sit-to-stand (STS). The purpose of this...
A major cause of deaths among the elderly relates to accidental falls. Such falls are of particular medical concern to this population because they often result in severe injuries, since senior citizens usually live alone and cannot ask for help when accidents happen. In this paper, we propose a fall detection system with the help of a Gaussian mixture background model to build the background before...
Trajectory planning can ensure the robot arm move smoothly and quickly to the target position and realize the humanoid robot hand grasping. In the paper, we proposed a trajectory planning of the H20 humanoid robot arm based on combination function method. It is composed of cycloid and cosine function with different frequency. The combination of cycloid function and cosine function adopted has solved...
Although many kinds of collision pre-warning algorithms and systems for vehicles were proposed in order to prevent accidents in past years, two problems have to be resolve in order to enhance the accuracy of collision detection. First, a vehicle does not always keep the same velocity when it is moving. Second, the curve road condition should be considered. In this paper, we proposed an Advanced Cooperative...
The vector components of acceleration sensitivity Γ for a closed-loop oscillator referenced to a wine-glass disk array-composite resonator employing tiny (~92 nm) electrode-to-resonator capacitive transducer gaps were measured along axes perpendicular and parallel to the substrate to be Γvertical~13.6ppb/g and Γlateral~4.92ppb/g, respectively, which are on par with commercial quartz-based oscillator...
With increasing number of aging people, taking care of the elderly will become more and more important for future society, especially for those elderly living alone. This paper presents an autonomous mobile robot Rola (Robot of LivingAid) , which can handle certain emergency conditions in a home setting to help the elderly through multi-modal sensing and control functions. The implemented functions...
