This voltage should be greater than the motional induced EMF. It is possible to obtain a replica of motional induced EMF in its winding using Permanent Magnet (PM) enhanced sensing scheme. Any PM rotor having even number of N-S poles may be suitable for such a scheme. In this paper, the feasibility study of a fault-tolerant BLAC motor using PM enhanced has been experimentally investigated. In actual practice input voltage of PM motor contains larger number of harmonics due to switching action thereby making it quite cumbersome to estimate the EMF induced in its coil. In PM enhanced sensing, the replica of induced EMF is available for each coil under dynamic condition. The scheme introduced can be suitably implemented for fault tolerant motor where the motional induced EMF of each of the winding segment of auxiliary winding may be amplified using commercially available Power Operational amplifier (P-OPAMP). The amplified voltage is used to activate the respective winding segment on the main winding.","PeriodicalId":250687,"journal":{"name":"2013 Texas Instruments India Educators' Conference","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127798530","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 main motivation to Infinite Coffee Cup is to detect the presence of a person and dynamically and non-Invasively estimate the amount of coffee in a circular cup on the table. One of the more popular devices used is Microsoft Kinect, which has cameras that capture both RGB and Depth data. Kinect is a low cost sensing device which provides two streams of images, 8 bit 3 channel RGB image and 11 bit single channel depth image. The system is fixed at the roof facing downwards and it takes a top view of the cup placed on the table. We use \"libfreenect\" [1] drivers which is an open source project, to stream data from kinect. We employ various image processing algorithms using Open CV (Open Source Computer Vision) which is a library of programming functions for real time computer vision. The algorithms are used to manipulate the data from kinect to, -Detect the circular coffee cups in the RGB image. -Overlay and correlate the depth values of cups in the depth image to get the height and amount of coffee in the cup.","PeriodicalId":250687,"journal":{"name":"2013 Texas Instruments India Educators' Conference","volume":"451 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127005902","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}

As one of its many applications, we illustrate its use in washing a car, with minimal usage of water. This idea can be extended to design robots capable of reaching remote points in skyscrapers, for painting, cleaning and allied purposes, which eliminates the need to put human life at risk.

The robot is controlled via a Wi-fi link which streams real time video back to the base station. The main processor is a TI Sitara AM335x ARM processor. It also acts as relay for the sensor data. Each node consists of three passive infrared detection circuits each covering a sector of 120 degrees and connects via the TI CC2530 ZNP chip. The raw PIR data is signal conditioned using an LM324 Op-amp. The nodes can be deployed easily due to their compact size. Their low power consumption and low cost makes them ideal for remote areas and can be deployed in large numbers.","PeriodicalId":250687,"journal":{"name":"2013 Texas Instruments India Educators' Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124151250","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}

Prakash","doi":"10.1109/TIIEC.2013.62","DOIUrl":"https://doi.org/10.1109/TIIEC.2013.62","url":null,"abstract":"Due to influx of vehicles on the road, citizens inevitably combat traffic congestion on a daily basis. This is underlined by the lack of parking infrastructure and shoot up of vehicle to human population ratio. The Robotic Valet Parking System uses the robotic valets, which are the vehicle carriers and parks the vehicles compactly in a given space of the parking area once the driver loads his vehicle at the loading bay. Robotic Valet Automated Parking System (APS) provides solution for the parking problems without the need for special construction for automation. The conventional concrete garages can be transformed into an automated parking system with the use of robotic valets. Since the robotic valet APS requires concrete flooring, which provides the fire separation, builders consider it approvable. The number and the position of the occupied vehicles can be determined without the deployment of the sensors in each of the parking slots. The vacancy of the parking garage is displayed on the LCD screen which is of benefit to the costumer. The central processing unit wirelessly controls the locomotion of robotic valets and the arrangement of vehicles in the parking area. We shall prove the space efficiency, accuracy, operational speed, safety and cost effectiveness of the proposed parking system. A functional prototype of a robotic valet is built which parks the vehicle loaded. The Unified Technology Learning Platform (UTLP) Kit, which has TI (Texas Instruments) ARM CORTEX A-8 microprocessor unit embedded in the TI OMAP 3530 applications processor, is the control unit and this monitors the movement of the robotic valet wirelessly. On producing the parking slip at the exit the robotic valet automatically retrieves the vehicle to the costumer.","PeriodicalId":250687,"journal":{"name":"2013 Texas Instruments India Educators' Conference","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130905796","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}
