“A novel volume measurement system for an irregular shaped tank”, Dr. K. Rajasekaran, Dr. P. Rajalakshmy, Dr. P. Subha Hency Jose, Mr. Joseph Chinnadurai, Mr. Devaprakash.
A novel technique to monitor the fuel volume in an automobile fuel tank is designed and implemented. The intelligent module comprises a resistive level sensing system, a non-linear curve fitting technique for calibration and the relevant controllers for implementation of the algorithms. The technique is validated using real time data obtained from the experimental set up and the results are found to be extremely promising. The system can be widely adopted for fuel volume measurement of tanks of different shapes by suitably modifying the calibration curve.
A Test set up device for AC contactor to automate HUM detection and method thereof” , Dr.K.Rajasekaran, Dr.X.Anitha Mary, Mr.J.Devaprakash.
The present invention discloses a system and method for measuring Hum on an Industrial contactor. The setup for the acquisition of hum comprises of an autotransformer, a hum detector, NI-DAQ and a personal computer. The supply voltage is given to contactor from the autotransformer through a switching circuit. The piezoelectric vibration sensor is placed on the side of the contactor. The vibration signal acquired by the Data Acquisition Unit (DAQ) is further processed by the algorithm developed for vibration analysis using the LabVIEW software. The signature of the vibration signal is compared to the predetermined signature set by the manufacturer, for the contactor at test, and the result is used for classification. Further, the voltage output from the voltage sensing circuit is given as an input to the Data Acquisition unit (DAQ) to assess pickup and drop down voltages. Finally the automated test system generates the report of the test result.
D. Pamela, Gerard Joe Nigel, A Low Cost Portable Cryotherapy Instrument for treating Sport Injuries.
Cryotherapy is used clinically with the intention of applying low temperature to the skin using liquid nitrogen or argon and considerably decreasing the pain and swelling of a patient's injured region. Cryotherapy is widely used to treat various types of damages in tissues. Precisely Sports injuries are very common tissue injuries and it demands for immediate application of low temperature to the damaged tissue. Thus the need of cryotherapy has been emphasized and hence the significance of inventing such a portable device for applying cryotherapy has been justified. The model proposed is first of its kind in the healthcare industry. This device is cheap and portable and hence can be used widely. This model is backed up with a rechargeable battery and hence made portable. The model developed can give variations in temperature between low and high ranging from -8°C to room temperature, but for treating tissue damage its advisable to maintain 8°C-12°C temperature ranges, which is a comfortable and perfect replacement for ice packs. Temperatures lower than this can cause ice burns on skin. Unlike the normal ice pack it can last for a longer time period. The time taken for instrument to cool is very less when compared to ice packs where one should wait until the liquid is turned to ice. Provisions for selecting the desired temperature and a digital display for indicating the temperature has been made in the design of the equipment. A temperature controller to maintain the desired temperature has been embedded into the device. Efficient cooling mechanism to dissipate heat that generates from the system has been successfully implemented so that efficient cold temperature could be tapped.
