The obtained results from the field measurements indicated that 3rd harmonics are located in the second and in the third quadrants of the complex plane, and the 5th harmonics are located in the first and fourth quadrant of the complex plane. It was observed that the principal variation between harmonics of the same frequency, generated by household equipment, was presented in the magnitude rather than in the phase angle; hence not a significant harmonic cancellation effect could be predicted for the household equipment under test.","PeriodicalId":166098,"journal":{"name":"2016 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116169016","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 device centers its operation in the use of the senses of touch, sight and audio, through the implementation of micro servos, mp3 DfPlayer module, low brightness leds and the bluetooth module HC-06 respectively. The electronic board Arduino Mega, is responsible for receiving the input signals and activate the peripherals, which generate the learning of the Braille code. The project is implemented in the “Unidad Educativa Claudio Neira Garzón” of the city of Cuenca, where users are able to learn the characters of Braille language, but not at the same pace, taking into account that two of the three subjects, who were tested, are people with vision and the third person is a nine years old student who attends the second year of basic education in the institution.","PeriodicalId":166098,"journal":{"name":"2016 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"80 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114101938","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}

Unfortunately, most commercial robot manufacturers do not provide open control architectures. To deal with this issue, in this paper the open architecture of the Catalyst-5 robot manipulator manufactured by Thermo Scientific is presented. The original control box was replaced by a custom-made controller fitted with servo drives and additional electronics to manipulate encoders and control the robot manipulator. A data acquisition card is located inside of a PC, which in turn hosts the control law. To validate the performance of the proposed open architecture a force/position controller based on the principle of orthogonalization was implemented. Experimental results demonstrate that the present open software/hardware control architecture is suitable and reliable for the implementation of complex tasks involving advanced control strategies.","PeriodicalId":166098,"journal":{"name":"2016 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131336108","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}

Operating under the subthreshold region, the amplifier is capable of running at high speeds, with a supply voltage (V<inf>DD</inf>) as low as ∼ 0.6V. The main contributions of this work are: First, a primarily current-mode rail-to-rail output stage is presented that employs Minimum Current Selectors (MCS) which monitor the sink-source currents of the output buffer transistors. Concurrently, Current Feedback Amplifiers (CFA) composed of Inverting Current Mirrors (ICM) regulate the minimum stand-by currents for either the non-sinking or non-sourcing output transistors, while allowing maximum currents to run through the sinking or sourcing transistors. As such, the output stage, in its basic configuration, can deliver a wide dynamic range at high speeds with V<inf>DD</inf> as low as ∼ V<inf>GS</inf>+2V<inf>DS</inf>. Second, a Floating Current Source (FCS) is utilized in the main amplifier that can also operate with V<inf>DD</inf> as low as ∼ V<inf>GS</inf>+2V<inf>DS</inf>. Montecarlo (MC) and worst case (WC) simulation show the following specifications are achievable: V<inf>DD</inf> minimum ∼ 0.6v; I<inf>DD</inf> ∼ 330nA; Input range rail-to-rail; offset voltage ∼ 6mV; Output range ∼ 25mV from the rails; open loop gain (Av) ∼ 78dB with unity gain frequency (fu) ∼ 1MHz and phase margin (PM) ∼ 40 degrees; power supply rejection ratio (PSRR) ∼ −83dB; common mode rejection ration (CMRR) ∼ −98dB; Slew rate (SR) ∼ 2V/us; Settling time (ts) ∼ 3uS to ∼ 2mV; rail-to-rail output voltage swing with R<inf>L</inf> ∼ 5K ohms, and size ∼ 120um/side.","PeriodicalId":166098,"journal":{"name":"2016 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132579336","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}
