The device measures internal changes in heat transfer due to the inclination. The device is functionally equivalent to a traditional proof-mass accelerometer. The proof mass in the new thick-film sensor is a gas. The gaseous proof-mass provides great advantages over the use of the traditional solid proof mass. A conditioning electronic circuit amplifies the signal variation induced by the inclination, compensating for the deviation due to the initial asymmetrical values of the bridge arms and their slow variations. Preliminary tests on the first prototypes show an accuracy of about 2% full scale output, repeatability of about 0.2/spl deg/ and resolution better than 0.1/spl deg/ over a /spl plusmn/20/spl deg/ range.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

The FPGA board is connected to the host computer through a PCI interface. The application system software running within Microsoft Windows environment is developed so that all the data generated during simulation can be downloaded and displayed on the host computer. Hence, the system acts like a logic analyzer with very large storage memory. Furthermore, the software provides interfaces and drivers for devices such as USB camera, computer monitor and PC soundcard so that the simulation data can be demonstrated over the host computer in real time. Because multimedia data is usually complicated and the size is huge, design and thorough verification are usually difficult and take lots of time. The proposed system is both versatile and convenient to use and verification of designs for multimedia applications becomes much easier. An MPEG-4 simple profile video encoder and a 3D surround sound processor are realized with the proposed system. Both cases can run in real time.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.
