Beginning with an introduction to 802.11b in general, 802.11 Security gives you a broad basis in theory and practice of wireless security, dispelling some of the myths along the way. In doing so, they provide you with the technical grounding required to think about how the rest of the book applies to your specific needs and situations. If you are a network, security, or systems engineer, or anyone interested in deploying 802.11b--based systems, you ll want this book beside you every step of the way.

ARM7硬件說明與開發
The ARM7 is a low-power, general purpose 32-bit RISC microprocessor macrocell for use in application or
customer-specific integrated circuts (ASICs or CSICs). Its simple, elegant and fully static design is
particularly suitable for cost and power-sensitive applications. The ARM7’s small die size makes it ideal for
integrating into a larger custom chip that could also contain RAM, ROM, logic, DSP and other cells.
A general technique for the recovery of signi cant
image features is presented. The technique is based on
the mean shift algorithm, a simple nonparametric pro-
cedure for estimating density gradients. Drawbacks of
the current methods (including robust clustering) are
avoided. Feature space of any nature can be processed,
and as an example, color image segmentation is dis-
cussed. The segmentation is completely autonomous,
only its class is chosen by the user. Thus, the same
program can produce a high quality edge image, or pro-
vide, by extracting all the signi cant colors, a prepro-
cessor for content-based query systems. A 512 512
color image is analyzed in less than 10 seconds on a
standard workstation. Gray level images are handled
as color images having only the lightness coordinate
