This firmware translates a PS/2 mouse to a USB mouse. The translator
firmware is entirely interrupt driven (with the exception of sending the
data via USB to the host.) An interrupt is generated when the PS/2 start
bit is received, at which time the firmware will begin its receive routine.
In addition to this interrupt, every 168ms a timer overflow interrupts the
main program and implements one state of the mouse state machine. This
state machine handles sending bytes to and translating bytes received from
the PS/2 mouse automatically. All of this is done in the background while
the main program runs in the foreground. The only operation that the main
program implements is sending mouse data to the PC via USB.
Libsvm is a simple, easy-to-use, and efficient software for SVM
classification and regression. It can solve C-SVM classification,
nu-SVM classification, one-class-SVM, epsilon-SVM regression, and
nu-SVM regression. It also provides an automatic model selection
tool for C-SVM classification. This document explains the use of
libsvm.
A d hoc 移動網絡是一種完全由移動主機構成的網絡. 網絡拓撲易變, 帶寬、能源有限是ad hoc 移動網絡
的主要特點. 針對這些特點, 目前設計的ad hoc 路由協議大多采用按需查找方式. 該文介紹了這方面研究的最新進
展, 對幾種典型的按需路由協議進行了說明、分析和綜合比較. 文中分析了目前協議存在的一些問題并提出了相應的改進方法. 最后指出了下一步研究方向.
PrintNow is a 32-bit application that runs only under Windows 95
or Windows NT 4.0. It allows your PrtScr and Alt+PrtScr keys to
print a screen capture directly to your printer instead of just
copying the image to the Windows clipboard. PrintNow can also
print any DIB image in the clipboard, regardless of its
original source. PrintNow supports multiple instances, it can
print multiple copies of a screen capture to the same printer
with different print settings, to several different printers,
or any combination thereof, with a single keystroke.
