Electro Uterine Monitor

May 16, 2005 by admin 0 Comments

The Electro Uterine Monitor software provides accurate data and rapid analysis of the uterine state. The system is a diagnostic monitor that can accurately determine the start of labor, based on electromyography technology.

EUM Electrode Positioning Configuration

Main Features

  • Simultaneously multi channel Logging, form different devices, using different technology:
    • USB: A real time application receive data from Analog to Digital device connected thought a USB, Supporting a different levels of sampling rates frequencies.
    • Serial Port RS232:  The software also connected to a 3D positioning sensor connected through a serial input.
    • User interaction: collects patient information, system configuration and settings.
  • Different layouts for the offline replay which allows a transparently review of the logged data.

Design Considerations

  • Development Environment: Choosing MFC visual studio, was fair enough to ensuring high performances in acquisition, saving and display.
  • Object Oriented: OOP is claimed to give more flexibility, easing changes to the program in the future.
  • Memory management: An advanced buffer design and memory management are required to allow such “real-time data acquisition” and
    “signal graphic display” software, to run far form any loss of data and all under the optimized system resources.

Highway Speed-Profile

The goal of transportation is generally stated as the safe and efficient movement of people and goods. To achieve this goal, designers use many tools and techniques.
One technique used to improve safety on roadways is to examine the consistency of the design. Design consistency refers to highway geometry’s conformance with driver expectancy. Generally, drivers make fewer errors at geometric features that conform with their expectations.

Figure (3) – Speed Profile, main screen
An inconsistency in design can be described as a geometric feature or combination of features with unusual or extreme characteristics that drivers may drive in an unsafe manner. This situation could lead to speed errors, inappropriate driving maneuvers, and/or an undesirable level of accidents. This program provides an estimate of the expected 85th percentile speed profile of cars and trucks. It also provides an estimate of the design consistency.
It is intended to be used for preliminary highway planning and as an estimation model to identify inconsistencies in horizontal design of two-lane highways. It is not intended to be used as a speed limit determination tool.
