PTAG - aktiv RFID-tag med GPS

Bengtsson, Christofer, Madsen, Kristoffer January 2008 (has links)
<p>Free2Move AB is developing products for the market within wireless communication</p><p>and identification, among those active RFID-tags. The company had an idea about</p><p>providing one of their active RFID tags with a GPS receiver and transmit positions via</p><p>an existing RFID protocol. Desire from the company was also the possibility to log</p><p>positions and measure temperature. The finished prototype should also be able to be</p><p>activated by movement. The company had proposal about components that were to be</p><p>used in the project. A large part of the work was to understand how these worked and</p><p>how to combine them to fulfill the requirements established in agreement with</p><p>supervisor at Free2Move. A PIC microcontroller was used in the design of the prototype</p><p>and software implemented for communication with GPS, RFID tag and other</p><p>components. The result was a working prototype where an existing RFID tag was</p><p>integrated in the same printed circuit board layout as the GPS receiver and other</p><p>components that were used in the project.</p>

Fjärrstyrt kamerafäste : HE Remote

Emanuelsson, Herman, Sjunnesson, Emil January 2013 (has links)
Vid tillfällen då det inte lämpar sig att stå vid en videokamera kan det lösas med ett fjärrstyrt kamerafäste. Exempel på tillfällen är på grund av platsbrist på en konsert, en högtidsceremoni där någon måste stå konstigt till för att få bra bild, ute i naturen där djur ska filmas utan att bli ivägskrämda eller vid personalbrist, en tight budget och måste styra flera kameror samtidigt. De system som finns tillgängliga på amatörmarknaden idag har antingen annan funktionalitet och passar sig inte för ovanstående problem eller har väldigt begränsad räckvidd och går inte att sammankoppla med en mobilapplikation. Detta projekt går ut på att ta fram en kostnadseffektiv och skräddarsydd lösning för ovanstående problem genom att utveckla ett fjärrstyrt kamerafäste i semiproffssegmentet där det via en handkontroll och vid senare skede med en mobilapplikation styr kamerans lutning och rotation även kallad tiltning och panorering. Skillnaderna mellan denna och befintliga lösningar är att med hjälp av Bluetooth-tekniken kan styra både med handkontroll och senare även med en mobilapplikation, anledningen till att det skall kunna styra med båda är att det inte alltid är tillåtet att använda sig av mobiltelefoner i alla miljöer där man vill filma och därför får ett bredare användningsområde för kamerafästet. / At times when it is not suited to stand by a video camera can be resolved with a remote controlled camera mount. Examples of occasions is due to lack of space at a concert, a solemn ceremony in which someone must stand awkwardly  to to get good image, out in nature where animals shall be filmed without being frightened away or when you have staff shortages, a tight budget and need to control multiple cameras simultaneously. The systems that are available in the amateur market today have different functionality and is not fitting for the above problem or have very limited range and cannot connect to a mobile application. This project aims to develop a cost-effective and customized solution for the above problem by developing a remote-controlled camera mount in semi-professional segment where you through a controller and at a later stage with a mobile application controls the camera angle and rotation also called tilt and pan. The differences between this and existing solutions are that by using Bluetooth technology can control both the controller and later on also with a mobile application, the reason why it must be able to control both is that it is not always allowed to use cell phones in all environments where you want to film and therefore have a wider range of applications for camera mounting.
