Dust Networks, Inc. is a company specializing in the design and manufacture of
for industrial applications including process monitoring, , asset management,
(EHS) monitoring and . They are headquartered in .
Dust Networks works with industry and standards groups such as , , , and
to help drive the adoption of interoperable wireless sensor networking products.
In 1997, , a professor of electrical engineering and computer sciences at the , conceived of and started the
project with
The Smart Dust project attempted to demonstrate that a complete sensor/communication system could be made of sensors one cubic millimeter in size. This involved advances in miniaturization, integration, and energy management. The project focus was independent of any particular sensor, and looked at both commercial and military applications including:
Defense-related sensor networks such as battlefield surveillance, treaty monitoring, transportation monitoring, and scud hunting.
Virtual keyboard sensors: by attaching miniature remotes on each fingernail, accelerometers could then sense the orientation and motion of each fingertip, and communicate this data to a computer in a wristwatch.
Inventory control: by placing miniature sensors on each object in the inventory system (product package, carton, pallet, truck warehouse, internet), each component could "talk" to the next component in the system. This evolved into today's
inventory control systems.
Product quality monitoring: temperature and humidity monitoring of perishables such as meat, produce, and dairy.
Impact, vibration and temperature monitoring of consumer electronics, for failure analysis and diagnostic information, e.g. monitoring the vibration of bearings to detect frequency signatures that may indicate imminent failure.
The project led to the founding of Dust Networks, to provide commercial applications of the above.

October 2007: SmartMesh IA-500 family of WirelessHART standards-based systems announced
July 2008: Launches initiative focused on the use of Internet Protocol (IP) networking in urban infrastructure, building automation, utility metering, and other wireless sensor networking applications

Wireless sensor networks attempt to increase transmission reliability and quickly adapt should the transmission fail and automatically route around failed links. This requires embedded networking intelligence that establishes, maintains and utilizes redundant multi-hop routing from source to destination.
Dust implements full-mesh networks, sometimes referred to as ‘mesh-to-the-edge’, which provides redundant routing to the edge of the network. In a full-mesh network every device has the same routing capabilities and is able to ‘decide’ where it belongs in the routing structure based on what other nodes it can communicate with, its proximity to the network gateway, and its traffic load. This allows for self-forming and self-healing. The multi-chip modules used to drive these networks are divided into 'gateways' and 'motes' (or mote modules). Gateways then tie back into larger networks used to make decisions within large industrial plants (oil refineries, chemical plants, produce facilities, etc.).
The company has evolved from using a proprietary protocol called
(Time Synchronized Mesh Protocol), to Wireless HART to launching an Internet Protocol-based initiative, in support of the Internet Engineering Task Force (IETF), focused on the use of IP networking in urban infrastructure, building automation, utility metering, and other wireless sensor networking applications.

: Hidden categories:你不曾发觉你总是用右手　牵着我但是心却跳动　在左边
历经找工作，天大真是不怎莫样，不管学生怎莫样，只要自己的就业率和名声...
现在才真正了解到什莫叫做“我爱天大，但是天大不爱我”...
爱校？想都不要想了！
今天天大给我的，我会还回去，不管是十年、二十年，还是下辈子...
&今天查了六级成绩，迷迷糊糊的就过了，500分，不多也不少，但至少了却了一桩心事。希望迷迷糊糊的找份好工作吧。。。
不得不承认，我开始变得容易失去希望。
尽管我以前一直是个不服输的人，我争取，我不肯放弃，但结果呢?现实就是那样血淋淋的摆在我面前，连让我脆弱的余地都不留。
本来以为心已经尘封，但是出现的那一刻，我真的不敢相信幸福就这样降临了。太像是在梦中了：那样美好，美好的不真实。
也许可能真的只是一场梦。短暂。而又美丽。
不管怎样，谢谢你带给我的快乐。
佛学中讲，人生有七苦：生、老、病、死、爱别离、怨憎会、求不得。
我想，这七苦，皆因我们有追求，对生命，青春，健康，对爱，对情感，对一切美好的追求。
因为我们有追求，所以我们会痛苦。
你和我，原本，都想要追求一份美好，所以有了故事的开头。
接着，我们发现这块已经变成了石头的星星其实并不美，也不好，所以有了故事的结尾。
年龄越来越大,人越来越成熟,感觉能力越来越强,却越发觉得自己不能左右的事情越来越多。
学校是这样一个场所,你每天要和身边的人打交道,有很多事情要处理,同样在学校里可能你还扮演着多个角色,某某社团的头目,某某女孩的姐姐,某某男孩的“哥们”,甚或是某某人的死敌,你想在人群中脱颖而出,不甘心碌碌无为,就要认真扮演好每一个角色,人生没有固定的剧本,没有导演喊NG,一切都靠自己来把握角色的性格特点,处事方式,肯定会觉得很累,而往往在这个时候你身边的人并不理解你,这是你感到很伤心的,你以为每天和你喜笑颜开的人就是你的好朋友,你以为你很仗义的帮了别人他就一定会报答你,甚至你以为为你喜欢的人做很多事她就一定会对你感兴趣.没有一定的事情,没有必须的事情,也没有理所当然的事情
即将失去一个人的滋味是什莫？是眼睁睁看着他走上错误的轨道自己却无能为力，你的愤怒你的悲伤你的眼泪或许能暂时让他刹车，可是前方的诱惑幻化成巨大的动力，不停召唤他奔腾的脚步，宽容的怀抱又怎能永远锁住那排山倒海般的心？苦苦顶着，苦苦与心魔对抗，可是总有一天会力气尽失，那时也就是全线溃败之日，他会山洪暴发般一泻千里离你而去，只留下你守着一地狼藉苟延残喘……
&体会过打针的滋味吗？不知道它何时会进针，不知道那刺入的疼痛会何等强烈。那针头高高的举起了，分明感觉到了那针尖的锋锐和想象中的痛感。害怕它刺入自己，又不堪折磨地期待它赶快扎进来，好让一切早点结束，可偏偏那只操纵的手就是迟迟不肯落下来……
Things can go wrong. And suddenly I
seriously know that:
Sometimes, what we want is exactly what we
But, sometimes …
Sometimes what we need is a new
命运以一种朦胧而诱人的姿态召唤着，但她们却不知道自己的人生要向左，还是向右。
许多真正的痛苦并没有长久留存，因为人有强迫自己遗忘的本能。
但一些愉快或不愉快的小片段却偏偏事与愿违地成为扎在心头的刺，在许多年后还会冷不丁跳出来提醒：在某个隐秘来处，她们曾有过怎样卑微的生活……
