42:为什么蓝牙的使用率会持续上升Why bluetooth use is on the rise
05/09/2013
Bluetooth has been with us for around 15 years. Named after Denmark's King Harald'Bluetooth'Blatand, who reigned in the 10th Century AD, it is a technology that everyone is aware of on their computers and phones, yet not many people choose to use. As a means of allowing devices to talk to each other cheaply and wirelessly over short distances, it has tended to stay largely in the shadows, leaving the limelight to the technologies it connects.
Now however, with the rapid grow-th in the use of mobile and sensing tech-nologies, along with the release of an updated version of the system, it means the list of its applications is growing steadily. From health and agriculture, to business and electioneering, it is quietly playing an ever more central role in many of our lives.
'It's a very flexible, low power, and predictable technology,'says Professor Roch Guerin, Chair of Computer Science and Engineering at Washington University, St. Louis.'Bluetooth targets lower transmission ranges and data rates than wi-fi,and as a result has lower cost and lower power consumption.'
These costs have dropped further, in some cases significantly, thanks to recent advances. Bluetooth Smart, launched in 2011,includes a smarter power management system that allows it to turn on, transmit data and shut down more quickly-in just a few milliseconds in some cases. Depending on the devices being connected and the data being transmitted, this updated system consumes anywhere between half and 1/100th of the power of the previous version. As a result, machines using Bluetooth that previously ran for a few months on a coin cell battery, can now run for years.
'Bluetooth classic is for sending steady streams of voice and audio,'says Suke Jawanda, Chief Marketing Officer of the Bluetooth Special Interest Group(SIG),which owns and licenses Bluetooth technology.'Bluetooth Smart is about sending packets of bits and data to applications.'

蓝牙进入生活已有15年左右的时间。蓝牙这个名称来自于丹麦十世纪的国王Harald“Bluetooth”Blatand。虽然这是一个大家都熟知的电脑和手机技术,但并不是很多人都选择使用它。蓝牙是一个低成本的近距离无线连接方式,可以为固定设备与移动设备的通信环境建立一个专门连接。
如今,随着快速增长的移动设备和遥感技术的使用,加之其又刚发布了一个升级版本的系统,蓝牙技术的应用范围正在逐渐扩大起来。从生命健康、农业到商业和竞选活动,蓝牙技术正在我们生活的许多方面悄然地起着重要的作用。
华盛顿大学计算机科学与工程系的主席Roch Guerin博士说:“这是一个非常灵活的、低功率和可预测的技术。由于蓝牙的目标传输范围和数据传输速率都低于wifi,因此,它具有更低的成本和更低的能耗。”
在一些情况下,由于近期技术的进步,蓝牙的成本会进一步降低。2011年推出的“蓝牙智能”就含有一个电源智能管理系统,能以更快的速度开启系统、传输数据和关闭系统——在某些情况下仅需要几毫秒。根据连接设备和数据传输的不同,这个升级后系统的电量消耗仅为原来系统的二分之一至百分之一之间。因此,使用一枚纽扣电池,原来可以使用几个月的蓝牙机器,现在就可以使用数年了。
蓝牙技术联盟拥有蓝牙技术和生产许可。该联盟首席营销官Suke Jawanda说:“经典的蓝牙技术可以发送连续的语音和音频。”蓝牙智能技术能将应用的数据包和数据发送到终端的设备上。

43:英国珍稀蝙蝠濒临灭绝Rare bat on brink of UK extinction
05/08/2013
'We also know that[it has]declined dramatically in the last century.'
'We know of three maternity colonies[colonies where the female bats give birth and raise their young]that have disappeared in the past few decades.'
Although the UK's grey long-eared bats have always been confined to the relatively warm south of England, they have now been squeezed into just a few fragmented colonies.
The bats are confined to small pockets along the south coast of England, including the Isle of Wight, with a small number found in the Channel Islands and a single one recorded in South Wales.
It is so rare, in fact, that BBC News was asked to keep the exact location of the colony we visited in Devon a secret, to avoid the bats being unnecessarily disturbed.
Dr. Razgour explained that the decline was linked to the'dramatic decline of lowland meadows and marshlands, the bat's main foraging habitats'.
'The long-term survival of the grey long-eared bat UK population is closely linked to the conservation of these lowland meadows and marshland habitats,'she said.
The Bat Conservation Trust is cal-ling on influential groups, including land owners, conservation organisations and Natural England, the government adviser on the natural environment, to manage the landscape around roosts.
They have also stressed the impor-tance of managing the land between known roosts, so the remaining colonies are connected and the bats are able to breed.
