21	Smart medicine alerting system Nali, Kuladeep January 2022 (has links) What is the purpose of medication? It’s job is to cure a disease.But taking medicine at the perfect time will definitely help anyonecure diseases immediately. There are so many situations when missingmedicine timing might happen unintentionally or even expected. Forexample, there are diabetic people who miss their shot of dose atperfect timing. Another example is the people with memory issuesdue to age or disease.There are many situations where missing medicine might causeproblems. Mainly in crisis situation like in hospital we need a re-minder that helps people take the preferred medicine at specified time.So that will be the problem statement of this thesis.The main objective of the thesis is to notify patient take correctmedicine with the help of easy equipment. When elders have a prob-lem we admit them in hospitals but due to COVID epidemic situa-tions hospitals are understaffed. Because of that the patients in hos-pitals may not be treated well. The personal has a busy schedule withCOVID situations so they can’t care must about each and every singledetails. This might causes major problems while giving minute dosesto patient where a 1mg medication change can lead to severe problemsfor a patients health condition. By providing a proper check up withpatient we can solve those problems more effectively. Arduino Uno Medication Supervisor HC-05 DS3231 Potentiometer Pharmaceutical Sciences Farmaceutiska vetenskaper
22	Utveckling av koncept för att reglera reaktiv effekt vid generatordrift via PLC : Framtagande och provning av prototyp / Development of concepts for regulating reactive power during generator operation via PLC : Creation and testing of prototype Gran, Erik, Hård, Erik January 2019 (has links) I projektet utreds möjligheterna kring att kunna kontrollera en generators reaktiva effektproduktion genom att styra magnetiseringsströmmen från en PLC. Som metod för styrning från PLC beslutades att en signal på 0-5V skulle användas. För att reglera magnetiseringen, och därmed i förlängningen den reaktiva effekten, beslutades att den befintliga manuella potentiometern skulle ersättas med två parallellkopplade digitala potentiometrar av typen MCP4261 som kontrollerades av en mikrokontroller. Att de digitala potentiometrarna skulle parallellkopplas beslutades efter en förstudie som visade på att det skulle resultera i en noggrannare reglering utan någon inskränkning på användbart reglerspann. Praktisk provning av mikrokontroller och digitala potentiometrar gav ett tillfredsställande och bra resultat med god upplösning. / This project investigates the possibilities of being able to control a generators reactive power production by controlling the excitation current from a PLC. As a method for controlling from PLC, it was decided that a signal of 0-5V should be used. In order to regulate the magnetization, and hence in the long term the reactive power, it was decided that the existing manual potentiometer would be replaced by two parallel-connected digital potentiometers of the type MCP4261 controlled by a microcontroller. The fact that the digital potentiometers would be connected in parallel was decided after a feasibility study which showed that in this way it would result in a more accurate regulation without any restriction on the usable control span. Practical testing of microcontrollers and digital potentiometers provided a satisfactory result with a good resolution. reactive effect reactance reactivity capacitance capacitivity inductance inductivity generator phase compensation microprocessor PLC arduino potentiometer reaktiv effekt reaktans reaktivitet kapacitans kapacitivitet induktans induktivitet generator faskompensering mikroprocessor PLC arduino potentiometer Annan elektroteknik och elektronik

24	Vestavěné zařízení pro ovládání digitální audio stanice / Embedded Device for Control of Digital Audio Workstation Svoboda, Tomáš January 2019 (has links) The aim of this work is to design an architecture of the embedded device that will be used for controlling DAW software in recording studio. First of all, attention is given to a brief summary of the necessary knowledge which is needed to design such kind of device. Af- ter that follows short survey of the existing solutions and description of protocols which can be used for communication with the recording software. Then, subsequent part of the thesis builds upon these foundations and further elaborates the device architecture by me- ans of decomposing it into several modules. In fact, two hardware modules are designed and manufactured, when each of them is conceived on a separate PCB with its own microcon- troller. Then the control firmware has been implemented for each of the modules. At the end of the work an aluminium enclosure, which holds both modules, is designed. The result of this work is a functional prototype of the assembled controller which can be used for the purpose of controlling DAW software.
25	Elektronicky řiditelný aktivní filtr 2. řádu / Electronically controlled active 2-nd order filter Ševčík, Břetislav January 2009 (has links) The diploma thesis deals with the modern design of the control circuits for digital potentiometers and their application in analog systems. The concept of the digital control is demonstrated on the electronically controlled active 2-nd order filter and programmable oscillator. The proposed design of the active filter describes a programmable active 2-nd order filter Sallen-Key. In this circuit it is possible independently programme cut-off frequency, Q factor and type of approximation with very good accuracy. The circuits of the designed filter and designed oscillator are simulated in PSpice (OrCAD), parasite effects and effects of the real parts are studied. Properties simulated circuits are compare with experimental results. These results appreciate quality and efficiency of the digitally controlled potentiometers in dependence on variable input circuit parameters. Integral part of this project is author’s universal control program called Digipot and comunications interface for many types of digital potentiometers with I2C, SPI or Up/Down interface. It is possible to use this device for many applications. The constructional details of the filter are presented at the end of this work. The software equipment is availability on enclosed CD.
26	Simulace a realizace laboratorního napájecího zdroje / Simulation and realization of laboratory DC power supply Mach, Ladislav January 2010 (has links) The thesis deals with analyses of the laboratory symmetrical supplies with adjustable output voltage. It also describes different kinds of current cut-out circuits and several most frequent supply connection schemes. Analyses (simulation program OrCAD) show the characteristics and behaviour of the mentioned supplies. To set the output voltage, operational amplifier structures or linear three-terminal voltage regulator are very often used. The suggested supply was tested and its parameters compared with the simulations. The value of output voltage and current can be controlled with a computer with a USB port. For controlling of the output voltage and current the digital potentiometers were used and controlled by I2C bus.

28	Digitálně řízený rezistor / Digital controlled resistor Sedlář, Petr January 2009 (has links) This master´s thesis deals with the design of the control circuits for digital potentiometers and their application in analog systems. Digital potentiometers are three-terminal resistors with an adjustable center connection. The digital potentiomneters enable to drive logic gates, LED drivers, LCD drivers, analog switches etc. Controlling of these mentioned devices is possible by the I2C 2- wire serial bus (invented by Philips). The digital potentiometers are used to control of the primary parameters like cut-off frequency and quality factor in the state variable filter and cut-off frequency in a passive filter. Both filters are simulated in PSpice and then compared with the measured results. Next parts of this master's thesis are a computer program and a exemplary protocol.
