These are possibly the 2 most important characteristics of wheelchair cushions for wheelchair users. Presence of a cushion cover and type of support structure the cushion is placed on are the variables that will be investigated. Displacement of the cushion surface over a series of loads comparable to human masses was measured. Displacement of the cushion surface was measured using a 3-D digitizer (Minolta Vivid 900) and computer software Rapidform 2001. Simulation of cushion properties was then carried out using software CosmosWorks 2005. Results indicate that the foam cushion exhibits the best pressure distribution characteristic, while cushion covers tend to decrease deformation and increase pressure on bone protrusions. Simulations also indicated that a symmetrical cushion appeals not to be ideal for users with asymmetrical weight distribution.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122075881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The EPC is built on the basis of Brent's path planner and the control force is generated by balance between the internal restoring force and external normal force. Simulation results show that the new EPC can not only follow an arbitrary curve as a guideway but also deviate from the guideway with a normal force to avoid obstacles. This EPC can also work in the singularity area, which was not solved ever before.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115342983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, an existing piece of curriculum is analyzed by axiomatic design approach and design matrices are made to check whether the independence axiom is satisfied or not. Second, functional requirements (FRs) are derived from the FRs of the existing curriculums developed through conventional methods. Constraints (Cs) are defined considering the time and subject. Design parameters (DPs) are conceived in physical domain to satisfy these specified FRs and Cs, and two alternative DPs for one FR are proposed. One of these alternatives having the least information content is selected by defining FRs as the minimization of the irrelevant subjects/topics and time. Also feasibility is estimated by comparing the information content of the redesigned curriculum with that of other curriculums in consideration of costs-involved, time, and subjects-relevance.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123521566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If left untreated, the skin can break open and become infected. This paper introduces a semi autonomous system based on control and monitoring of patient's skin to bed surface temperature for bed sores prevention. The developed system consists of bed surface implanted temperature sensors interfaced with a microcontroller for sensing the temperature change in patient's skin to bed surface. Based on the amplified signal from temperature sensors, the microcontroller makes appropriate decision on the mode (heater / cooler) and speed of the fan module for blowing warm / cool air to the bed surface. Furthermore, an alarm module was implemented to alert the nurse to reposition the patient only if patient's skin to bed surface temperature exceeds a predefined threshold thereby saving human resources. Evaluation tests were completed and adequate results were obtained.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125864607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Portability, modularity, compactness & degree of freedom are the main concerns of the device. Applied postoperatively, this device may be used on an inpatient or an outpatient basis. The designed device can be used for different exercises of wrist and elbow just by simply plugging in or out some of the links or by adjusting the position of some of the links. In addition, instead of going with the usual approach of using different actuators for different degrees of freedom, a single actuator is used in this project. By adjusting the links position, the patient can perform different exercises. The therapist or the patient will then select appropriate settings to run different exercises.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122297723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Software is designed and developed under the visual studio.net 2005 platform and using visual basic programming, which can be installed and run in any PC under Operating System of windows 2000 or / and XP. A voice controlled, user-friendly user interface is carefully designed, so that user can use not only standard keyboard and mouse, but also the voice to control home environments including lights, TV, radio, VCD/DVD player, fan, and air conditioner. Furthermore, the self-deigned software applies home automation control idea to internet access and PC application software access with the features of surfing the internet, sending and receiving emails, using other PC software such as Microsoft office. Considering the disabled has difficulty to move around and control their hands and fingers, the system is more valuable and useful to these people and will provide great convenient to them. Testing has been demoed that the accuracy of voice commands can reach as high as over 90% under quiet environments.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"15 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114025264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
