摘要:
A mobile platform including a body, hybrid leg-wheels and driving mechanisms is provided. The hybrid leg-wheels are disposed around the body for carrying the body moving on a working surface. The driving mechanisms are disposed between the corresponding hybrid leg-wheels and the body. Each driving mechanism includes a driving axle connecting the corresponding hybrid leg-wheels and the body. Each driving mechanism provides the corresponding hybrid leg-wheel a rotational degree of freedom and a translational degree of freedom, wherein the rotational degree of freedom and the translational degree of freedom are driven independently. The rotational degree of freedom allows the hybrid leg-wheels rotating along an axis of the driving axle, and the translational degree of freedom allows the hybrid leg-wheels translating relative to the driving axle, wherein the rotational direction is substantially perpendicular to the translational direction.

The invention concerns a method for making an article having a tunable adhesive, said method comprising applying strain to mechanically deform a substrate in at least one direction; applying a rigid coating layer on the substrate; and releasing the strain to form an article having a rippled surface. Ripple characteristics can be altered by mechanical strain in real time which further changes the adhesion properties.

A compensation method compensates for a length offset between a first transmission line and a second transmission line of a differential signal transmission. The compensation method includes calculating a transmission speed of a first signal in the first transmission line, measuring lengths of the first and second transmission lines, calculating a transmission time of the first signal in the first transmission line, and calculating a relationship between permittivity values of the first and second transmission lines. The compensation method further changes the permittivity values of the first and second transmission lines according to the relationship.

摘要:
A printed circuit board includes a layer. A layer of copper is covered on a surface of the layer. A through hole passes through the printed circuit board. A number of thermal engravings are defined in the layer around the through hole. Each thermal engraving is a groove defined in the surface of the layer, without covered with the layer of copper. The number of thermal engravings are not in contact with each other.
