Abstract: A securing apparatus includes a housing, a cam member, and a movable device that can be moved in a first direction to engage a first surface of the cam member to cause the cam member to move from a first position to a second position. When the cam member is in the first position, first and second movable members can be moved relative to the housing. When the cam member is in the second position, second and third surfaces of the cam member press respectively against the first and second movable members to trap the first and second movable members respectively between the second and third surfaces of the cam member and the housing such that the first and second movable members are fixed relative to the housing.
Abstract translation: 固定装置包括壳体，凸轮构件和可移动装置，其可沿第一方向移动以接合凸轮构件的第一表面，以使凸轮构件从第一位置移动到第二位置。 当凸轮构件处于第一位置时，第一和第二可移动构件可相对于壳体移动。 当凸轮构件处于第二位置时，凸轮构件的第二和第三表面分别压靠在第一和第二可动构件上，以将第一和第二可动构件分别夹在凸轮构件和壳体的第二和第三表面之间， 第一和第二可动构件相对于壳体是固定的。

Abstract: An electromagnetic motor includes a stator and an armature arranged to move substantially linearly relative to the stator in an intended direction during operation of the motor. A first and second flexure are connected to a first end of the armature. Each flexure has a longest portion which lies substantially in a plane that intersects a plane in which the armature lies at a substantially right angle. The flexures allow motion of the armature in the intended direction while resisting motion of the armature in one or more other degrees of freedom.

Abstract: A conditioning system includes a sample chamber capable of receiving a specimen as well as first and second specimen-holding fixtures positioned within the sample chamber and configured to apply mechanical stimulation to a specimen held by the fixtures. The system has at least one port capable of providing a fluid to the sample chamber. The chamber is sized and shaped so that it can be inserted into an imaging device which can record images of a specimen held by the fixtures.

Abstract: This document provides mechanical seals that include one or more rolling diaphragms. In one example embodiment, this document provides double rolling diaphragm seals that are usable in conjunction with various types of equipment including, but not limited to, accelerated life testing systems. In such a context, the double rolling diaphragm seals facilitate high-speed linear modulation of a variable volume pressure vessel, while maintaining precise volumetric control. Such an arrangement can facilitate an essentially frictionless linear actuation system having a long stroke, long service life, and precise volumetric control. In addition, this document provides linear actuator systems that can be used in adverse environmental conditions.
