The design of an interface unit is described, in which RS232 serial data is converted to latched parallel data on 22 independent lines. The data direction of each line is programmable through the serial port. Two picocontrollers are employed in a parallel processing mode to give the required number of I/O pins, and data on the shared serial line is coded to separate data streams to the individu...

This study analyzes the current situation of practical teaching system computer hardware courses in local undergraduate colleges, scrutinizes experimental environment construction, contents, and methods courses, proposes a new for so as to meet needs transformation development well application-oriented talent training.

In this paper, using a personal computer (PC), the practical implementation of scalar and vector control methods on a three–phase rotor surface- type permanent magnet synchronous machine drive is discussed. Based on the machine dynamic equations and the above control strategies, two block diagrams are presented first for closed-loop speed controlling of the machine drive/system. Then, the desig...

Wearable, camera based, head–tracking systems use spatial image registration algorithms to align images taken as the wearer gazes around their environment. This allows for computer–generated information to appear to the user as though it was anchored in the real world. Often, these algorithms require creation of a multiscale Gaussian pyramid or repetitive re–projection of the images. Such opera...
