The Actuator
The purpose of the Actuator is to create a practical device that passively exercises\r the lower legs to help prevent blood clots, Deep Vein Thrombosis (DVT), in\r wheelchair-bound individuals of any age. The secondary purpose of the device is to\r improve range of motion of the lower legs and speed the recovery of their leg action. It is hoped that this invention will help to prevent DVT, and allow some people to even use their legs again, through passive or active muscular motion. The invention was produced using a number of prototypes and design sketches. Although the current model is quite functional, as it keeps the users legs in motion, it is still in the prototypic design stage.\r The Actuator is a simple to use, easy to retrofit device. It is also portable and will be\r able to attach onto the front of any wheelchair. It harnesses the motion of the wheelchair to drive the users legs in a circular motion.\r The invention was tested in a closed and controlled environment: the duration of the\r Actuator’s use was constant, a doctor was present to take blood pressure and heart rate, and the rotation speed of the user’s legs was controlled by keeping the wheelchair speed constant. The data was collected by monitoring heart rate and skin surface temperature of healthy individuals, and blood pressure and heart rate of a wheelchair bound individual.\r As seen with both experiments (wheelchair bound, and healthy individuals) heart rate\r increased. In addition, the wheelchair bound individual’s heart rate also noticeably\r increased, with an evident increase in blood pressure as well. However, skin surface\r temperature is sensitive to surroundings and often provides little indication of deep vein blood flow, thus the skin surface temperature measurements were too inaccurate for any conclusions to be formulated.\r The inventor’s grandmother had developed DVT’s in 2005, and passed away because of them. Had she been given an Actuator it may have prevented such a tragedy. Her death was the driving force behind the project’s development. Over the time period that this project has been in process, the true potential of this invention has been realized.\r I truly believe that it will revolutionize the way that we treat people in wheelchairs, and the way people in wheelchairs can treat themselves.
Prototype Educational resources for teaching basic pneumatic
The didactic prototype for the teaching of the pneumatic Basic is designed, so teachers can instruct knowledgement of pneumatics focused to identification, handling and application of its elements based on constructivist theory in which the student learns making, working on projects and in a collaborative way. This implies that his presentation should include the basic elements to be used in this study area, as well as allowing that the student can interact with it, still easy to use, and take them by the teacher into his area of education, which can be a classroom, room, Auditorium, workshop, lab, and even training courses to the industry, the only thing that requires is compressed air (2 to 4 bars). As well as, to create a secure environment for the user when this is manipulating. Its construction based on a compact, lightweight and ergonomic, structure to ensure that it can be transported without difficulty. Also that must comply with the minimum essential to enable the student to acquire competencies in the curriculum which consider the identification, handling and application of pneumatic elements; IE has the following 2 directional valves 3/2 NC, 1 directional valve 3/2 NC-operated with a knob, 2 valves 3/2 pneumatic drive, a 5/2 valve NC NC of stable pneumatic drive, 1 valve of simultaneity or function, and 1 valve selector or function, or double effect with pressure regulator piston1 piston of double effect, 1 piston for simple effect, 1 valve 3/2 NC with motorized drive and roller.
自動化健康管理系統之研製
This study of health diagnosis based on using computer signal analysis technology. In order to make health management more perfect. The main points of this study are wrist pulse and body temperature information, remit to the database of the computer, analyze with the computer. With the internet network , transmit it to the medical center in order to carry and control, seek medical advice, prevent infective disease from spreading, defending healthy purposes of people, this research system includes the following six functions:(1) Automation measured: Can prevent popular disease from spreading , and ensure the medical personnel to avoid being infected.(2) The heart and lungs function warning system:When the pulse beats too fast or slowly, computer will send out warning signal immediately .(3) The body temperature is unusually warning system: When the body temperature is too high or too low, will send out warning signal immediately.(4) Pathology analyzed: Will pick and fetch the pulse wave form, which use the computer procedure to carry on frequency spectrum in order to analyze, then compared with database, with the purpose of analyze pathology. (5) The health managed: Remit the physiological information that quantity examines to the database of computer, offer pathology analysis, carry on the prevention of the disease. (6) Analysis results of the human exercise: With the operation of the database, we can analyze and obtain the effect that all previous sports accumulate .本研究係運用電腦訊號分析科技、資料庫軟體,使健康管理更為完善。研究重點為擷取人體手腕脈象、體溫生理訊息,匯入電腦資料庫,以電腦進行分析。藉由網際網路,傳輸至醫療單位,達到遠端監控、緊急就醫、防止傳染性疾病蔓延,守護國民健康之目的,本研究系統包含下列六大功能:(1) 自動化檢測:可防止流行疾病蔓延,並保障醫護人員避免遭受感染。(2) 心肺功能異常警示:脈搏跳動過快或過慢,立即發出警示。(3) 體溫異常警示:當體溫過高或過低,會發出警示。(4) 病理分析:將擷取脈搏波形,運用電腦程式進行頻譜分析,與資料庫比對,藉以分析病理。(5) 健康管理:將量測之生理訊息匯入電腦資料庫,提供病理分析,進行疾病之預防。(6) 運動成效分析:藉由資料庫之運作,可解析獲得歷次運動累積之成效。
