International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / One of the beauties of mathematics is its ability to demonstrate the relationship between apparently unrelated subjects. And this is not only an aesthetic attribute. The insight obtained by seeing relations where they are not obvious often leads to elegant solutions to difficult problems. This paper will demonstrate a mathematical relation between telemetry and juggling. Any given pulse code modulation (PCM) format can be mapped onto a juggling pattern. The Inter-Range Instrumentation Group (IRIG) 106 Class I PCM formats are a subset of all juggling patterns while the Class II PCM formats are equivalent to the set of all juggling patterns (within some mathematically precise definitions). There are actually quite a few mathematical results regarding juggling patterns. This paper will also discuss how these topics relate to tessellations, bin packing, PCM format design, and dynamic spectrum allocation. One of the shortcomings of human nature is the tendency to get caught up in a particular topic or viewpoint. This is true of the telemetry community as well. It is hoped that this paper will increase the awareness that there are a variety of areas of theory outside of telemetry that may be applicable to the field.

No decorrer do desenvolvimento de argamassa expansiva para lavra de rochas ornamentais, verificou-se a deficiência de equipamentos que pudessem avaliar a pressão e a temperatura originada por esta argamassa durante o processo de expansão. Este trabalho descreve o projeto de desenvolvimento de um equipamento para este fim. O projeto foi desenvolvido utilizando tecnologia de microcontroladores, conversores analógico-digitais do tipo SAR (successive approximation register), célula de carga do tipo S, termopares do tipo K e termistores. Em todos os itens do projeto, utilizaram-se CAD (Computer Aided Design). O armazenamento dos dados obtidos se dá em cartão de memória SD e a comunicação através de barramento USB e serial, permitindo a operação na ausência de computadores nos mais diversos ambientes com a mais ampla conectividade. Além do equipamento em si, o programa embarcado no microcontrolador e o programa de computador, responsável pela aquisição e transferência dos dados também foi desenvolvido e testado, exibindo resultados dentro dos padrões desejados. / The correct evaluation of the properties of a material is essential so that their performance meets the expectations for which it was designed. During the development of expansive mortar for mining of ornamental rocks, there was a lack of equipment that could evaluate the pressure and temperature caused by the mortar during the expansion process. This paper describes a device for this purpose. The project was developed using microcontroller technology, analogue to digital converters of the type SAR (Successive Approximation register), load cell S-type, K type thermocouples and thermistors. In all items of the project, was used CAD (Computer Aided Design). The storage of data occurs in SD memory card and communication through USB and serial bus, allowing operation in the absence of computers in various environments with the broadest connectivity. Besides the equipment itself, the program embedded in the microcontroller and the program responsible for the purchase and transfer of data was also developed and tested, showing results within the desired standards.
