Perptetua电力普克 正在研发中的未来科技
由于没有部件磨损,在佩尔佩图阿电力普克,发明了从太平洋西北国家实验室和佩尔佩图阿电源技术团队,是一种环保型电源能够提供持续的动力,以小型电子设备。曲棍球的技术是基于正在申请专利的设计,使热电发电机的电力转换成热能对环境的低功耗各种用途。 

核心技术采用了独特的配置,利用小(> 2摄氏度的超薄装配热电偶)温度差异发生在应用程序,例如地对空(环境,自然,水,空气,或皮肤空中接口)。个人热电偶,由1.5厘米宽,1厘米高的一个几微米厚,保存在一个链接链到一个薄,弹性塑料基板,采用溅射薄膜沉积热电偶到组装成各种形状和尺寸的产品。这些设备产生的分歧从最低温度为1 ° C至2 ° C的有用的能源,而较大的温差产生相应较大的产出。这些器件也可以设计为不管哪一方是温暖的热或冷。
With no parts to wear out, the Perpetua Power Puck, invented by a team from Pacific Northwest National Laboratory and Perpetua Power Technologies, is an environmentally friendly power source able to provide sustained power to small electronic devices. The puck's technology is based on patent-pending thermoelectric generator designs that allow the conversion of ambient thermal energy into electric power for a variety of low-power uses.

The core technology uses an assembly of ultrathin thermocouples in a unique configuration that exploit small (>2°Celsius) temperature differences occurring naturally in the environment of the application (e.g. ground to air, water to air, or skin to air interfaces). The individual thermocouples, 1 cm high by 1.5 cm wide and a few micrometers thick, are deposited in a linked chain onto a thin, flexible plastic substrate, using sputtered thin-film deposition thermocouples to be assembled into products of all shapes and sizes. These devices generate useful energy from temperature differences as low as 1°C to 2°C, while larger temperature differences produce correspondingly larger outputs. The devices can also be designed to work regardless of which thermal side is warmer or cooler.

全国点火运动的最终目标是“控制的成果,持续的核聚变和能量,首次在实验室环境中不断增长。”这是一个艰巨的任务需要许多具有创新了。一个必要的步骤是将一个设备的组装融合的目标,将成为在地球上的聚变点火的过程能发明的微型太阳。 

机器人精密装配机核聚变点火建设目标,在劳伦斯利弗莫尔国家实验室,利弗莫尔,加利福尼亚州发明,是能够执行这项任务,它涉及拼凑一个小,而复杂的组装,需要微米间隙。这些目标的尺寸精度是2至20微米,这表明在经营上的一个糖块大小的装配机操控精度:100 nm的精度和分辨率100毫克力反馈。本机有一个工作量的一个鞋盒大小。
The ultimate goal of the National Ignition Campaign is the achievement of "controlled, sustained nuclear fusion and energy gain for the first time ever in a laboratory setting." It's a tall task that has required many innovations already. One necessary step was the invention of a device that would be capable of assembling the fusion targets that will become the miniature suns on Earth during the fusion ignition process.

The Precision Robotic Assembly Machine for Building Nuclear Fusion Ignition Targets, invented at Lawrence Livermore National Laboratory, Livermore, Calif., is able to perform this task, which involves piecing together a small, but complex assembly that requires micrometer clearances. The dimensional accuracy of these targets is 2 to 20 micrometers, which indicates the manipulative precision of the assembly machine: 100 nm precision and 100 mg resolution force feedback in an operating arena the size of a sugar cube. The machine has a work volume the size of a shoe box.

小型γ相机的高解析度从布鲁克海文国家实验室和Hybridyne成像技术是核医学成像探针定位在前列腺癌组织。该系统采用了紧凑型高分辨率碲化镉锌(CdZnTe探测器或长株潭)探测器阵列耦合的低噪声脉冲加工电子,高性能图像采集软件。它结合了深冷冷却半导体的高清晰度能力,在闪烁常温操作能力。 

辐射传感器依赖于晶体材料,长株潭。当由一个事件的X或γ-射线,微小的电流脉冲产生的冲击也是可以读出电路与电子测量晶体。 

整合成一个跨直肠探头的探测器和电子产品,最大限度地减少之间的成像系统和前列腺的工作距离,因此允许泌尿科取得了注入少量放射性示踪更好的信号。这种能力需要更快速的测量,改善形象,为病人和更大的舒适度。
The Compact Gamma Camera for high-resolution imaging from Brookhaven National Laboratory and Hybridyne Imaging Technologies is a nuclear medical probe to localize cancerous tissue in the prostate gland. This system utilizes a compact high-resolution cadmium zinc telluride (CdZnTe or CZT) detector array coupled to low-noise pulse processing electronics, and high performance image acquisition software. It combines the high-resolution capability of cryogenically cooled semiconductors, with the ambient-temperature operation capability of scintillators.

The radiation sensor relies on a crystalline material, CZT. When struck by an incident X- or gamma-ray, a tiny current pulse is generated in the crystal that can be measured with an electronic readout circuit.

Integrating the detectors and electronics into a trans-rectal probe, minimizes the working distance between the imaging system and the prostate gland, so allowing urologists to obtain better signals with a small amount of injected radioactive tracer. This capability entails more rapid measurements, improved images, and greater comfort for the patients.
