Abstract
Description
遠隔にある物体などの始動および位置決めに使用される制御システムは、空気式、液圧式、および電気機械式システムを含み得る。こうした制御システムを使用することにより、自律型デバイスなどの多様な物体の動きを制御できる。こうした型のシステムは、それぞれ、特定の条件下において特有の利点を有する。空気式システムは圧縮気体を送ることによって力を供給でき、液圧式システムは低圧縮性の液体に依存するシステムである。
本明細書中において、縁端領域を制御可能に封止できるアクチュエータおよびその方法が開示される。1つ以上の実装形態において、アクチュエータが開示される。アクチュエータは、液圧力を伝達するよう構成される流体非透過膜と、流体非透過膜によって定められた区画とを含んでよい。上記区画は、中央領域と、中央領域から延在し中央領域と流体連結された縁端領域と、中央領域と縁端領域との間にあり噛合要素および連結要素を備える可逆性封止と、誘電性流体とを含んでよい。
本開示内容の概要が上記に簡潔に示されているが、上述される本開示内容の特徴の詳細を理解できるよう、実装形態に言及することによって、本開示内容をより具体的に説明する。こうした実装形態のうちいくつかは、付属の図面中に図示される。しかしながら、注目すべきことに、付属の図面は、本開示の典型的な実装形態のみを図示するものであるため、本開示内容の範囲を限定していると考えられるべきではない。本開示は、これら以外の同様に効果的な実装形態を可能にしてよい。
本明細書中に開示される実装形態は、概して、アクチュエータに関する。記載される実装形態によれば、アクチュエータは、さらなる電気入力がなされなくても始動位置を維持し得る。アクチュエータは、誘電性流体を含有してよい区画を定める流体非透過膜を含む。流体非透過膜内には、可逆性封止が存在する。この軟質の液圧式アクチュエータは、可逆性封止を封止することによって、アクチュエータへの電力が遮断された後でも作動位置を保つよう構成されていてよい。可逆性封止は、流体非透過膜の上記区画内における流体の通過を遮断し得る1つ以上の噛合部位を含んでよい。
