福禄克公司的Fluke190 SeriesII系列 ScopeMeter®示波表带有电气隔离通道，安全等级高，适合工业应用。此系列便携式示波表十分坚固耐用，同事具有台式示波器的高性能，应用范围从对微电子电路进行故障排查，一直到功率电子应用中的测量一应俱全。
Fluke190 SeriesII系列示波表是第一款针对CAT IV工业环境制造的四通道示波器。这些示波器具有CAT III 1000V/CAT IV 600 V安全等级，适合在三相、四相应用中进行测量，如测量工业电机、可变速驱动器、UPS 和变频器，同时测试输入、输出和控制信号。具有采样高速度、高分辨率：采样率高达2.5 GS/s，分辨率达400 ps。拥有用户一直期待的新功能，如 USB 连接和高级智能电池管理技术（供全天操作）。
Fluke190 SeriesII系列示波表仍是唯一的一种具有即触即测(connect and view)这一功能的示波器，可非常方便地捕获、分析未知的复杂波形。拥有创新的外型设计，提供了一个用于挂钩和螺纹嵌入件的相机附件安装座，可以安装标准相机附件。带有一个安全槽，如果需要离开示波器而让其在无人看管的情况下进行记录，则可以将示波器锁定。
放飞风筝需要娴熟的技能，Festo公司凭借其“空中自动化风筝”首次证实运用机电学原理可以实现风筝全程自动化控制。这是其在运用流动气流核心技术上的新发展。
“空中自动风筝”包含两个分别用机电控制器操纵的双线风筝。运用伺服电机和人造风，这两个风筝就可以实现室内自动化操作。各风筝线通过快速开关阀连接到Festo公司生产的DMSP射流臂，它可以缩短风筝线的长度。如果风筝断线，通过射流臂收缩风筝线就可以使其平稳飞行。It takes a fair amount of skill to fly a kite. With its Sky_liner project, Festo has become the first company to demonstrate that fully automated control can be achieved with the aid of mechatronics, thus linking a new development to its core competency of automation using moving air.
Sky_liner consists of two two-line kites, each of which is controlled using a mechatronic control unit. The two kites are operated automatically indoors, using servo motors and artificial wind. Each line is connected via fast-switching valves to a fluidic muscle DMSP from Festo, which shortens the line and counterbalances the kite by contracting when the kite breaks away.

以自然界的鳐鱼为模板的“空中鳐鱼”是一种由远程遥控的氦气气囊和羽翼振动产生驱动力组成的混合体。它轻便的设计借助氦气的浮力让它可以在广阔的空中“遨游”，这种方法与水中的鳐鱼相似。
“空中鳐鱼”的驱动力由羽翼振动产生。利用射线效应并基于与四周有连接的拱侧翼交替推拉运动的原理，私伺服控制的羽翼可以上下移动。当一侧受到压力时，它几何形的结构会自动向受力的反方向卷曲。一个伺服驱动两片侧翼交替地纵向移动，驱使羽翼上下运动。Air_ray, modelled on the manta ray, is a remote-controlled hybrid construction consisting of a helium-filled ballonet and a beating wing drive. Its lightweight design enables it to “swim” in the sea of air using the lift from the helium in a similar way to the manta ray in water.
Propulsion is achieved by a beating wing drive. The servo drive-controlled wing, which can move up and down, utilises the Fin Ray Effect and is based on alternate pulling and pushing flanks connected via frames. When pressure is exerted on one edge, the geometrical structure automatically curves against the direction of the influencing force. A servo drive pulls the two flanks alternately in longitudinal direction, thus moving the wing up and down.
