Abstract:
An organic thin field transistor is disclosed. The organic thin field transistor includes a first and a second insulting layers, a metal structure and an organic layer serving as an active layer. Materials of the first and the second insulting layers are different, and by performing an etching process, a surface of the metal structure and a surface of the second insulting layer are effectively aligned. Because of the high flatness of the surface of the metal structure and the second insulting layer, a continuous film-forming property and crystallinity of the active layer of the organic thin field transistor are improved, so as to achieve a better the electrical characteristic.
Abstract:
The present invention provides a dual riding and driving tricycle in juxtaposing link, particularly for one that can be pedaled by two drivers in side-by-side coordination manner so that the drivers and tricycle will incline integrally without tumbling or overturning possibility; The main feature is that at least one articulation mechanism and a resilient tension mechanism are disposed between the primary bicycle body and auxiliary cycle body, wherein, said articulation mechanism serves in synergy an articulation parallelogram while said resilient tension mechanism counteract the deformation of the articulation mechanism to resume the stable equilibrium so that the integral of the primary bicycle body and auxiliary cycle body can automatically maintain harmonic coordination and stability when driving over bumpy road or corner turn.
Abstract:
A positioning method for a sensor node is provided, and the method includes steps of: providing a first antenna having a first omnidirectional radiation pattern on a first plane; rotating the first antenna about an axis substantially parallel to the first plane; transmitting a wireless signal while the first antenna rotates about the axis for every a predetermined central angle; receiving the wireless signal at the sensor node; obtaining Received Signal Strength Indications (RSSIs) of the respective wireless signals; and determining a location of the sensor node according to the RSSIs.
Abstract:
A dual riding and driving tricycle in juxtaposing link comprises a primary bicycle body, an auxiliary cycle body and an articulation mechanism including a resilient tension mechanism.Primary bicycle body comprises a saddle sat by a primary rider, a front wheel controlled by a steering handle, a rear wheel and a pair of pedals to drive.Auxiliary cycle body comprises an auxiliary saddle sat by an auxiliary rider, an auxiliary wheel with a hub shaft located between hubs of front wheel and rear wheel in primary bicycle body and a pair of pedals to drive.Articulation mechanism comprises a left holding base, a right holding base and two parallel linking trough beams being disposed between both holding bases.Resilient tension mechanism comprises plural elastic elements connected on articulation mechanism respectively. Thereby, primary rider and auxiliary rider can independently tread respective pedals to drive synergistically.
