摘要: An electromechanical actuator arrangement (50) comprises an electromechanical motor (10) and a rail arrangement (35). The rail arrangement (35) has a rail (30) relative which the electromechanical motor drives in a main displacement direction (3). The electromechanical motor has electromechanically active actuators attached to a motor block (20) and are arranged to provide an actuating action against the rail. The rail arrangement has further at least one guide member (31) provided parallel to the main displacement direction. The guide members have a guiding surface (36) facing the motor block. The motor block in turn has guidance surfaces (37) facing the guiding surface of the guide members. The guiding surface or the guidance surface has a tangent line parallel to the main displacement direction. The other one of the guiding surface and the guidance surface has a tangent surface in a second plane parallel to the first plane

摘要: A ratchet apparatus includes a first member, a rack, and a second member that is selectively movable in first and second directions with respect to the first member. A first pawl is mounted with respect to the first member and is biased into engagement with the rack. The first pawl and the rack are configured such that engagement of the first pawl with the rack prevents movement of the first pawl relative to the rack in the first direction. A second pawl is mounted with respect to the second member for movement therewith in the first and second directions. The second pawl is biased into engagement with the rack. The second pawl and said rack are configured such that engagement of the second pawl with the rack prevents movement of the second pawl relative to the rack in the first direction.

摘要: The present invention provides electroactive polymer transducers that produce out-of-plane deflections. The transducers form a set of surface features based on deflection of an electroactive polymer. The set of surface features may include elevated polymer surface features and/or depressed electrode surface features. Actuation of an active area may produce the polymer deflection that creates one or more surface features. A passive layer may operably connect to a polymer. The passive layer may comprise a thicker and softer material to amplify polymer thickness changes and increase surface feature visibility.
