Gamified Music Learning System with VR Force Feedback for Rehabilitation

Many conditions cause loss of coordination and motor capabilities in the extremities. One such condition is stroke, which affects approximately 15 million people worldwide each year. [1] Many robotic systems have been developed to assist in the physical and neurological rehabilitation of patients who have suffered a stroke. As a result of this project an actuator to be used for hand rehabilitation using visual processing and Bowden cables was designed. This project aims to use the design of the actuator combined with gamification elements to create an interface to be used in future robotic rehabilitation systems as well as address the compliance problem found in rehabilitation

Semiautomation of irrigated basins and borders: III. Control elements and system operation

Irrigation application duration is an important factor influencing surface irrigation efficiency. Most methods of semiautomatic timing and control use mechanical timers for (1) direct gate release by the timer, and (2) timers designed for use with electrical components such as solenoid or electric motor-actuated releases. A trip-cord gate release system and water sensors were also used to semiautomate irrigation. The trip-cord system uses the energy of an opening or closing gate to either open or close other gates in the operating sequence. Semiautomatic gates, described in articles I and II of this series, and their associated controls were tested on a basin and three border irrigation systems on two farms during a five-year period. The semiautomatic controls provided operator convenience and reduced water and labor use

Modeling and parametric optimization of 3D tendon-sheath actuator system for upper limb soft exosuit

This paper presents an analysis of parametric characterization of a motor driven tendon-sheath actuator system for use in upper limb augmentation for applications such as rehabilitation, therapy, and industrial automation. The double tendon sheath system, which uses two sets of cables (agonist and antagonist side) guided through a sheath, is considered to produce smooth and natural-looking movements of the arm. The exoskeleton is equipped with a single motor capable of controlling both the flexion and extension motions. One of the key challenges in the implementation of a double tendon sheath system is the possibility of slack in the tendon, which can impact the overall performance of the system. To address this issue, a robust mathematical model is developed and a comprehensive parametric study is carried out to determine the most effective strategies for overcoming the problem of slack and improving the transmission. The study suggests that incorporating a series spring into the system's tendon leads to a universally applicable design, eliminating the need for individual customization. The results also show that the slack in the tendon can be effectively controlled by changing the pretension, spring constant, and size and geometry of spool mounted on the axle of motor

Revision to the SUDAS Traffic Signal Design Guide, TR-546, 2009

Changes in technology have an impact on standard practice, materials, and equipment. The traffic signal industry is constantly producing more energy-efficient and durable equipment, better communications, and more sophisticated detection and monitoring capabilities. Accordingly, this project provides an update to the traffic signal content within the Statewide Urban Design and Specifications (SUDAS) Design Manual and Standard Specifications. This work was completed through a technical advisory committee with a variety of participants representing contractors, the Iowa Department of Transportation, cities, consultants, vendors, and university research and support staff

SCDOT traffic signal design guidelines 2021

The purpose of the South Carolina Department of Transportation Traffic Signal Design Guidelines is to establish guidance, procedures and specifications that promote uniformity in the design of traffic signals. It is intended to clarify expectations and expedite the production and review of signal plans. These design guidelines include signal plan drafting guidance and specialized signal designs to ensure that plans properly convey the extent and character of the work to be performed, as well as the operation of the signal upon completion of the project
