3D Environmental force : position impedance variation for different motion parameters

The skill preservation of an expert has been a serious problem for countries with aging population because decrease of the number of successors. The concepts of haptic database and force sensor recorder which have been developed recently suggests solutions of using third multimedia type of haptic communication. Haptic information is a bilateral information of the law of action and reaction. The reaction from real world includes not only position and force information but also environmental impedance. In this paper, the behavior of environmental impedance has been studied with the changes of the different motion parameters like applied force, velocity, position and depth on the object 3D space. This idea is exemplified using a rubber balloon and a rubber sponge which is often modeled using simple linear equations. The experimental results show the importance of considering motion parameters when abstracting haptic information for a haptic database. Nonlinear impedance variations against the motion parameters suggest the necessity of adopting complex haptic abstraction techniques

Keynote paper - real world haptics applied to forceps in robot surgery

This paper presents the technological achievements in realizing the force feedback in surgical robots. No force sensor is used in sensing the force. Disturbance observer and its variant, reaction torque observer is used to detect the force. Bilateral control is used to transmit vivid sensations from the forceps end to the surgeon

Short-Term Electricity Demand Forecasting Method for Smart Meters

The short-term electricity demand forecasting has become one of the major research area in power system engineering. By combining the smart metering to the short term demand forecasting techniques, new features can be added to save on demand and electricity bill. This paper illustrates the methodology used to forecast electricity demand over short period of time which can be used with smart meters. Polynomial fitting with interpolation is used to forecast the demand by taking the apparent power sample points from smart meters. The outcome of this work will be beneficial to the residential or industrial electricity consumers to control the demand side loads. It will help the industrial consumers to save on maximum demand charge with the introduction of warning message or residential consumers to reduce their electricity bill by cutting down non-essential loads in peak hours

Knowledge on heart patients through stethoscopic cardiac murmur identification for E-Healthcare

Cardiac murmurs are the sounds produced by the abnormal passage of the blood flow inside the heart due to the diseased valves or tissues. Identifying the type of the murmur can diagnose the cardiac pathology related to that particular murmur. This paper describes a researched digital stethoscope that can be used as a stethoscope as well as a murmur identification device. To capture the heart beat, a chest piece of a traditional stethoscope is used with a condenser microphone attachment. Then the signal is amplified and Alters out the noise and sent to the ARM processor. At the processing module, sampling is carried out and stores the sampled data if the data transmission is not being done. Then the sampled data is transmitted to a central location using radio frequency transmitter module to carry out the signal processing. If the user wishes, the signal processing can be done in the stethoscope itself since the ARM processor is in the stethoscope unit
