“…The images of the charge coupled device-chip in the streak camera are read out via a PCI-framegrabber board by a computer enabling data transfer in video rate (30 Hz). Terzic et al [19] used state-of-the-art equipment from Hamamatsu. It is a complete streak system for fluorescence lifetime spectroscopy.…”

The development of a high-speed digitizer system to measure time-domain voltage pulses in nanoseconds range is presented in this work. The digitizer design includes a high performance digital signal processor, a high-bandwidth analog-to-digital converter of flash-type, a set of delay lines, and a computer to achieve the time-domain measurements. A program running on the processor applies a time-equivalent sampling technique to acquire the input pulse. The processor communicates with the computer via a serial port RS-232 to receive commands and to transmit data. A control program written in LabVIEW 7.1 starts an acquisition routine in the processor. The program reads data from processor point by point in each occurrence of the signal, and plots each point to recover the time-resolved input pulse after n occurrences. The developed prototype is applied to measure fluorescence pulses from a homemade spectrometer. For this application, the LabVIEW program was improved to control the spectrometer, and to register and plot time-resolved fluorescence pulses produced by a substance. The developed digitizer has 750 MHz of analog input bandwidth, and it is able to resolve 2 ns rise-time pulses with 150 ps of resolution and a temporal error of 2.6 percent.

The shape memory alloys exhibit a number of remarkable properties, which open new possibilities in engineering and more specifically in biomedical engineering. The most important alloy used in biomedical applications is NiTi. This alloy combines the characteristics of the shape memory effect and superelasticity with excellent corrosion resistance, wear characteristics, mechanical properties and a good biocompatibility. These properties make it an ideal biological engineering material, especially in orthopaedic surgery. In this work, modular plates for the osteosynthesis of the long bones fractures are presented. The proposed modular plates are realized from modules, completely interchangeable, made from Titanium or Stainless steel materials, having as connecting elements U-shaped staples made of Nitinol. Using computed tomography (CT) images to provide three-dimensional geometric details, and SolidWorks CAD software, the virtual models for humerus bone and for modular platesare generated. For numerical simulation we used VisualNastran software. We have obtained the displacements diagram, the von Mises strain diagram and von Mises stress diagram. Using the Rapid Prototyping 3D Zcorp 310 Printer system, we have obtained the prototype for the human humerus bone and for the plate modules. In vitro experiments are realised on the cadaver bones using metallic modular plates. The advantages of the modular plates are presented.
