Soft Pneumatic-Network (Pneu-Net) Actuators (SPAs) have been used extensively in making soft grippers, due to their simple driving forms and large bending deformation. However, the capabilities of regular SPAs complex gripping application environments are alone insufficient. This work, thus, proposes a modular gripper that combines functionalities herringbone actuators. The deformation characte...

Pneumatic actuators convert pneumatic energy into mechanical motion. This motion can be linear or rotary. Linear motion is feasible with pneumatic cylinders (e. g. single-acting cylinder, double-acting cylinder, rodless cylinder) and pneumatic artificial muscles (PAMs). Pneumatic artificial muscle is the newest and most promising type of pneumatic actuators. PAM is a membrane that expands radia...

OBJECTIVE To show the efficacy and comfort of pneumatic bag packing after the endoscopic nasal surgery. Pneumatic bag packing may be recommendable in terms of comfort and efficacy after endoscopic nasal surgery. Significant findings: There were statistical significant differences between the pneumatic bag packing and the expansive sponge packing regarding subjective symptoms and objective findi...

This project aims to develop a novel large stroke asymmetric pneumatic servo system of a hardware-in-the-loop for path tracking control under variable loads based on the MATLAB Simulink real-time system. High pressure compressed air provided by the air compressor is utilized for the pneumatic proportional servo valve to drive the large stroke asymmetric rod-less pneumatic actuator. Due to the p...

OBJECTIVE National Football League (NFL) concussions occur at an impact velocity of 9.3 +/- 1.9 m/s (20.8 +/- 4.2 mph) oblique on the facemask, side, and back of the helmet. There is a need for new testing to evaluate helmet performance for impacts causing concussion. This study provides background on new testing methods that form a basis for supplemental National Operating Committee on Standar...

AIM Previous research has shown that general practitioners (GPs) rarely use pneumatic otoscopy or tympanometry as recommended by best practice guidelines for diagnosing otitis media. The purpose of this study was to determine whether a multimodal, interactive training workshop on the techniques of pneumatic otoscopy and tympanometry would improve the confidence of GPs for the diagnosis of otit...

This paper describes the development work, and design and engineering tasks performed, to provide a fully automated sampling system for the Waste Treatment Plant (WTP) project at the Hanford Site in southeastern Washington State, USA. WTP is being built to enable the emptying and immobilization of highly active waste resulting from processing of irradiated nuclear fuel since the 1940s. The Hanf...

BACKGROUND Intrasphincteric injection of botulinum toxin is a new treatment option for achalasia. AIMS To compare the immediate and long term efficacy of botulinum toxin with that of pneumatic dilatation. METHODS Symptomatic patients with achalasia were randomised to botulinum toxin (22 patients, median age 57 years) or pneumatic dilatation (20 patients, median age 56 years). Symptom scores...

Soil vapor extraction (SVE) is one of the most commonly used technologies for soil remediation contaminated sites, and use models to accurately predict evaluate operational effectiveness SVE a necessary part site contamination treatment projects. A pneumatic model-based equipment model proposed comprehensively describe operation process. Though numerical simulation, influence fan frequency, air...
