    Abstract: The invention relates to a making a sealed duct from a vehicle cab post. There is a simple and effective method of making such a cab post. The method includes providing a cab frame with a hollow cab post having an air vent in a sidewall thereof and open first and second ends. The method also includes attaching a piece of unexpanded foam to a clip. The clip has a base forming a foam piece support to which the piece of unexpanded foam is attached. The clip has a gripping member, and an arm connecting the base to the gripping member. The method further includes inserting the clip and the foam piece through the vent and into the post so that the unexpanded foam piece is inside the post and spaced apart from an edge of the vent and between the vent and the first end of the post. The gripping member is coupled to the post so that the gripping member grips an edge of the vent. The cab frame and/or the post is then heated so that the foam expands and forms a seal within the post between the vent and the first end of the post. The result is a cab post with a sealed lower end wherein conditioned air from a roof mounted HVAC unit will flow from the upper end of the post, through the post to the vent and out of the vent and into the interior of the cab.

    Abstract: MEMS structures are provided that compensate for ambient temperature changes, process variations, and the like, and can be employed in many applications. These structures include an active microactuator adapted for thermal actuation to move in response to the active alteration of its temperature. The active microactuator may be further adapted to move in response to ambient temperature changes. These structures also include a temperature compensation element, such as a temperature compensation microactuator or frame, adapted to move in response to ambient temperature changes. The active microactuator and the temperature compensation element move cooperatively in response to ambient temperature changes. Thus, a predefined spatial relationship is maintained between the active microactuator and the associated temperature compensation microactuator over a broad range of ambient temperatures absent active alteration of the temperature of the active microactuator. In an alternative embodiment wherein the active microactuator is suspended within a frame above the substrate, the MEMS structure holds at least a portion of the active microactuator in a fixed position relative to the substrate over a broad range of ambient temperatures absent active alteration of the temperature of the active microactuator. By actively altering the temperature of the active microactuator, the active microactuator can be controllably moved relative to the temperature compensation microactuator and/or the underlying substrate. Related methods of compensating for the effects of ambient temperature variations are provided. Further, an overplating technique is provided for precisely sizing a gap defined within a MEMS structure.

    Abstract: Mounting systems for micro-electromechanical system (MEMS) structures are provided including a non-Newtonian fluid having a threshold viscosity that is positioned between a MEMS base member and the MEMS structure so as to position the MEMS structure relative to the base member. A MEMS actuator is coupled to the MEMS structure. The MEMS actuator is positioned to cause movement of the MEMS structure relative to the MEMS base member by generating a force sufficient to exceed the threshold viscosity of the non-Newtonian fluid when the MEMS actuator is actuated. The MEMS structure may be a MEMS mirror positioned for pivotal movement about a bearing member to control tilt of the MEMS mirror.

    Abstract: Microneedle arrays are fabricated by providing a sacrificial mold including a substrate and an array of posts, preferably solid posts, projecting therefrom. A first material is coated on the sacrificial mold including on the substrate and on the array of posts. The sacrificial mold is removed to provide an array of hollow tubes projecting from a base. The inner and outer surfaces of the array of hollow tubes are coated with a second material to create the array of microneedles projecting from the base. The sacrificial mold may be fabricated by fabricating a master mold, including an array of channels that extend into the master mold from a face thereof. A third material is molded into the channels and on the face of the master mold, to create the sacrificial mold. The sacrificial mold then is separated from the master mold. Alternatively, wire bonding may be used to wire bond an array of wires to a substrate to create the sacrificial mold. The first material preferably is coated on the sacrificial mold by plating. Prior to plating, a plating base preferably is formed on the sacrificial mold including on the substrate and on the array of posts. The inner and outer surfaces of the array of hollow tubes preferably are coated with the second material by overplating the second material on the inner and outer surfaces of the array of hollow tubes.

    Abstract: In embodiments of the present invention, a microelectromechanical actuator includes a beam having respective first and second ends attached to a substrate and a body disposed between the first and second ends having a sinuous shape. The body includes a portion operative to engage a object of actuation and apply a force thereto in a direction perpendicular to the beam responsive to at least one of a compressive force and a tensile force on the beam. The sinuous shape may be sinusoidal, e.g., a shape approximating a single period of a cosine curve or a single period of a sine curve. The beam may be thermally actuated or driven by another actuator. In other embodiments, a rotary actuator includes first and second beams, a respective one of which has first and second ends attached to a substrate and a body disposed between the first and second ends. Each body includes first and second oppositely inflected portions. The bodies of the first and second beams intersect one another at points at which the first and second oppositely inflected portions of the first and second bodies meet. The bodies of the first and second beams are operative to engage the object of actuation and rotate the object of actuation around the point of intersection responsive to at least one of compressive force and tensile force on the first and second beams. Related methods are also described.
