Fischertechnik CNC model
That model has been built in June 1990, but it became like on the photo
in the year 1993. It is a CNC Lathe (maybe not a very good expresion) controlled
with PC, at that time AtariST. Contact for more information...
Program for CNC Control written in Turbo Pascal.
With option load a file with CNC coordinates can be pluged in program, where first the simulation must be done to check the model. Coordinates file can be made by any text editor.
Reasearching Molecular Dynamics on the liquid model simulation
Abstract We investigated liquids using molecular dynamics with hard spheres model and made a computer simulation. We give a description of the collision time detection between molecules. We use two dimensional simulation, based on the simple empirical potential. The results gives us a clear performance of the molecules velocity and the dependence of pressure on density.
KEYWORDS: molecular dynamics, hard spheres, molecule velocity, liquid pressure
Development of the external control unit for the implantable stimulation system
Software development and hardware outline
At University College London an implantable stimulation system has been developed to be used in paraplegic patients to restore function in the lower extremities.The system comprises of an external control unit, a transmitter unit and the actual implant itself. The main task of our period here at UCL was to develop the software for the control unit (using assembler language) and to develop a proposal for the control circuitry.
Motorola 68HC11 was used for control until. It receives 44 bits from computer , makes Hamming and Manchester encoding, sends to implant, measures coupling and adjusts DC voltage for modulation with RF. More can be read on colleges site. http://www.medphys.ucl.ac.uk/posters/bugb/bugbpost.htm
