Pneumatic Grasping Device Including Sensor with Hybride Pressure Cascade System

Radial compression guided by mean artery pressure versus standard compression with a pneumatic device (RACOMAP).

BACKGROUND Transradial access is the approach of choice in many laboratories for diagnostic coronariography or percutaneous coronary interventions (PCI) because of its lower vascular complication rate than the femoral approach. However, this approach has a higher rate (5-10%) of asymptomatic radial artery (RA) occlusion. METHODS We conducted a prospective, controlled, single-centre trial stud...

Cascade position control of a single pneumatic artificial muscle–mass system with hysteresis compensation

The inherent hysteresis in a pneumatic artificial muscle (PAM) makes it difficult to control accurately the position of the PAM’s end effector. This hysteresis causes energy loss and the area of the hysteresis loop is dependent on the amplitude of the motion and on the underlying causes of the hysteresis phenomenon. This means that if the hysteresis energy loss is properly compensated, a more a...

Farm Operation Monitoring System with Wearable Sensor Devices Including RFID

To increase agricultural productivity and promote efficient management in modern agriculture, it is important to monitor the field environment, crop conditions, and farming operations instead of simply relying on farmers’ experiences and senses. However, it is difficult to realize such monitoring automatically and precisely, because agricultural fields are widely spaced and have few infrastruct...

Design of Infrared Sensor Based Measurement System for Continuous Blood Pressure Monitoring Device

An Underactuated Multi-finger Grasping Device

In this paper, a mechanical model for an underactuated multi-finger grasping device is presented. The device has single-tendon, three-phalanx fingers, all moved by only one actuator. By means of the model, both the kinematic and dynamical behaviour of the finger itself can be studied. The finger is part of a more complex mechanical system that consists of a four-finger grasping device for robot...
