Kommunikation genom att använda människokroppen som  överföringsmedium, med kapacitiv koppling mellan hud och sensor, har varit ett pågående forskningsområde för PAN (Personal Area Network) sedan Thomas Guthrie Zimmerman introducerade tekniken 1995. Anledningen till detta är att undersöka fördelar och användningsområden för en kommunikationsmetod som ej sänder ut RF-signaler och därmed minska risken för obehörig avlyssning. Denna rapport beskriver ett examensarbete som undersöker möjligheten till eliminering av USB- till UART-konverterare på Microchip BodyCom genom mjukvaru-USB-stack och kombinera denna med Body Coupled Communication funktionalitet i en gemensam mikrokontroller. Vidare studeras om programkoden i Body Coupled Communication sändare kan modifieras för att utöka funktionaliteten. Det var givet i förutsättningarna att mikrokontroller från Microchip skulle användas, vidare var lågt pris respektive låg strömförbrukning viktigt, särskilt för sändaren. Metoden för att uppnå detta har varit användning av Microchip BodyCom development kit tillsammans med Microchip USB low pin count development kit och Microchip USB firmwareframework. Resultatet blev att USB- till UART-omvandlare kunde integreras med Microchip BodyCom genom att använda mjukvaru-USB-stack och en modifierad programkod för BodyCom i en gemensam mikrokontroller. Endast fantasin sätter gränsen för vad Body Coupled Communication kan användas till. Det skulle t.ex. vara möjligt att utbyta elektroniska visitkort genom en handskakning eller öppna en låst dörr endast genom att ta i handtaget. / Communication using the human body as a transmission medium, the capacitive coupling between the skin and sensor, has been an active research area for PAN (Personal Area Network) since Thomas Guthrie Zimmerman introduced the technique in 1995. The reason for this is to examine the benefits and uses of a communication method that does not emit RF signals and thus reduce the risk of unauthorized interception. This report describes a thesis that examines the possibility of elimination of USB to UART converter on Microchip BodyCom through software USB-stack and combine this with Body Coupled Communication functionality in a single microcontroller. Furthermore, studies on if the application code in Body Coupled Communication transmitters can be modified to extend functionality. It was given in the conditions that microcontrollers from Microchip should be used, furthermore, low price and low power consumption were important, especially for the transmitter. The method for achieving this has been the use of Microchip BodyCom development kit with USB Microchip low pin count development kit and Microchip USB firmware framework. The result was that the USB- to UART-converter could be integrated with Microchip BodyCom, using software USB-stack and a modified program code for BodyCom in a single microcontroller. Only your imagination sets the limits for Body Coupled Communication can be used for. For example, it would be possible to exchange electronic business cards by a handshake or open a locked door only by using the handle.

This thesis proposes the platform for the observation of a new type of electromagnetic interface mode, Coupled Interface Mode, and studies the utilization of this mode in second order nonlinear interaction in AlGaAs. The dispersion relations for theoretical examination of the modes are developed and used to design a waveguide structure that accommodates a three wave mixing process utilizing coupled interface modes. The waveguides are fabricated according to optimized fabrication recipes and characterized for linear and nonlinear properties. Second harmonic generation is adopted for the demonstration of nonlinear interaction, due to its convenient experimental set-up. Three different laser sources are used to pump the waveguides and second harmonic light is generated and characterized. Coupled interface modes in conjunction with other types of modes also existing within the same structures, offer the possibility to explore three-wave mixing processes such as sum and difference frequency generation.

Amazonitic K-feldspar is characteristic of evolved granitic pegmatites of NYF (niobium-yttrium-fluorine) type, associated with A-type granite emplacement. In this work, I focus on four notable examples of such an association: (1) West Keivy, Kola Peninsula, Russia, (2) Saint-Ludger-de-Milot, Quebec, (3) Lac Sairs, Quebec, and (4) Morefield, Virginia. A fifth locality, the Broken Hill metamorphosed exhalative-type volcanogenic deposits in Australia, is an unusual type of amazonitic K-feldspar formed in an ore environment. A total of nineteen samples of amazonitic K-feldspar were characterized geochemically and mineralogically on the basis of X-ray diffraction, electron-microprobe and laser-ablation ICP-MS analyses. Lead, as an essential requirement for formation of the blue-green amazonitic color, has received particular attention. In every case, the analytical data show elevated amounts of Pb and rare alkalis, which strongly partition into the K-rich phase of the perthite intergrowth. Unusual micrometric grains, highly enriched in Pb, are found in cracks in the material from West Keivy. Some of the grains represent a new mineral species, a Pb-dominant feldspar. The presence of amazonitic K-feldspar in a granitic pegmatite is more than a curiosity. It can shed light on important petrogenetic issues such as metasomatic rejuvenation of crustal rocks prior to regional melting in a period of extension.
