Three-Dimensional Electrocardiography in the Rat

Rice, Peter J. 01 January 1992 (has links)
Three-dimensional electrocardiography with computerized analysis provides a means to rapidly collect and quantitatively analyze electrocardiographic data from rats. Electrical activity at each point in time can be expressed quantitatively as a vector with magnitude and direction. Rats are fitted with plate and needle electrodes in three mutually perpendicular axes: X (right to left), Y (rostral to caudal), and Z (ventral to dorsal). Electrocardiographic signals are recorded on paper and also collected at 1000/sec using an IBM-compatible computer equipped with a fast A/D convertor. Signals are analyzed using an interactive program written in Turbo PASCAL which transforms data into an array consisting of vector magnitude and direction at each time point. The data are further used to produce both a tabular report and graphic output. This method retains simplicity while extending the accuracy of electrocardiographic (ECG) measurement. It literally adds another dimension of information to the three-lead ECG most commonly measured in rats.

[en] A DIGITAL CONTROLLER FOR A GONIOMETER / [pt] CONTROLE DE UM GONIÔMETRO DE DIFRAÇÃO

MOISES HENRIQUE SZWARCMAN 30 January 2007 (has links)
[pt] Este trabalho descreve parte de um controlador digital para um goniômetro de difração, usado na determinação dos elementos presentes em uma amostra de material por meio de difração de raios X. O processo de análise é sumariamente descrito, de modo a evidenciar as funções que o controlador deve realizar. Baseado nestas funções, a estrutura do programa de controle é discutida e os problemas de sua implementação, em um microcomputador de uso geral, são examinados. Os problemas de entrada e saída de dados dão discutidos e as rotinas de conversão são apresentadas. Finalmente, os problemas de interface de circuitos e suas soluções são apresentadas e discutidas. / [en] This work describes part of a digital controller for a goniometer, used to determine the components that are present in a material sample by means of diffraction of X rays. The process of analysis is briefly show to make clear the performance expected for the controller. Based in the functions the controller should achieve, the Control Program structure is argued and the problems of its implementation in a microcomputer are examined. The problems that apper in input-stream data and output data-stream are ergued and conversion routines are presented. Finaly, the problems of interface of circuits and their solutions are presented andargued.

[en] CENTRAL COMPUTER OF A MICROCOMPUTER NETWORK CALLED MULTIPUC / [pt] COMPUTADOR CENTRAL DE UM SISTEMA DISTRIBUÍDO DE MICROCOMPUTADORES - MULTIPUC

SHEILA DORFMAN LAUFER 18 April 2007 (has links)
[pt] Este trabalho faz parte do projeto de um sistema distribuído de microcomputadores, MULTIPUC, em desenvolvimento no Laboratório de Engenharia e Sistemas de Computação (LESC) DA PUC/RJ. Neste trabalho descreve-se o projeto e desenvolvimento de duas máquinas: - O computador Central do MULTIPUC - controlador Inteligente de Comunicação O computador Central do MULTIPUC é baseado no microprocessador 8086 da Intel e sua finalidade é gerenciar os acessos dos microcomputadores satélites do MULTIPUC às memórias secundárias e dispositivos periféricos e ainda, a comunicação dos satélites entre si e com máquinas externas ao MULTIPUC. O Controlador Inteligente de comunicação é um processador dedicado à tarefas de comunicações externas e é baseado no microprocessador 8085 da Intel e no controlador programável de DMA 8237 da Intel. / [en] This work is part of a microcomputer network Project called MULTIPUC which hás been developed at the Laboratório de Engenharia e Sistemas de Computação (LESC). This work is a description of the design and implementation of two machine: - The MULTIPUC Central Computer - The communication Intelligent Controller The MULTIPUC Central Computer is based on the Intel 8086 microprocessor. Its main purpose is to manage the accesses of the MULTIPUC microcomputers called SATÉLITES to secundary memories and peripherals and also the communication of SATÉLITES among themselves and other computeres external to MULTIPUC. The communication Inteligent Controller is a processor dedicated to tasks of external communications and is based on the Intel 8085 microprocessor and the Intel 8237, programmable DMA Controller.

[en] FUNCTIONAL TEST OF MICRO-02 / [pt] TESTE FUNCIONAL DO MICRO-02

LUCIANO SERGIO BRITO NICOLAU DA COSTA 11 June 2007 (has links)
[pt] Este trabalho consiste na apresentação das rotinas de testes que forma desenvolvidas visando a verificação do funcionamento do microcomputador desenvolvido no Grupo de Eletrônica da PUC (GELUC): o MICRO-02 Essas rotinas de testes constam de microprogramas e também de programas realizados com o auxílio do repertório de instruções do microprocessador central (CPU - 8008) do microcomputador. Elas visam apenas o teste funcional do sistema não se preocupando com a localização da falha. Entretanto, através dos resultados de partes já testadas, pode-se tirar conclusões que permitam um grau de localização mais preciso da falha. / [en] This work consists of a presentation of test routines that were developed taking into account the verification of the Microcomputer´r functioning developed by GRUPO DE ELETRÔNICA DA PUC (GELUC): the MICRO-02. These test routines consist of microprograming and also of programs developed with the aid of the instructions report of the microcomputer´r central microprocessor (CPU - 8008). They only intend the functional test of the system, and do not take into account the localization of the failure. However, through the results of parts which have already been tested, one can have conclusions that allow a more precise degree of localozation of the failure.
