摘要： An imaging device for in vivo medical applications that enables minimally invasive surgical procedures. The imaging device includes an elongated frame having a base, a module housing, and an optional helical member interposed between the base and module housing. The imaging device further includes an actuation unit positioned within the frame that engages the module housing causing the frame to bend at the optional helical member. The module housing includes an imaging module and may include other modules including tools used for laparoscopic surgery.

摘要： The first objective of this paper is to take an existing design for a shape-shifting surface (SSS) and make it waterproof, making it an effective barrier to fluid flow. The second objective is to minimize internal stresses in the device during operation, by optimizing the kinematic geometry of the SSS. The first objective was achieved by adding a waterproof membrane between the layers of the SSS, where the membrane had an origami fold pattern that enables the membrane to mimic the kinematics of the SSS. The second objective was achieved by creating a two objective optimization routine, which determined the kinematic geometry of the SSS which would minimize the internal stresses due to compression/tension of the flexure portion of the SSS during operation. The resulting SSS is easier to operate due to lower stresses, and has a membrane which prevents transverse fluid flow and mimics its motion.

摘要： A shape-morphing space frame (SMSF) utilizing the linear bistable compliant crank-slider mechanism (LBCCSM). The frame's initial shape is constructed from a single-layer grid of flexures, rigid links and LBCCSMs. The grid is bent into the space frame's initial cylindrical shape, which can morph because of the inclusion of LBCCSMs in its structure. The design parameters include the frame's initial height, its tessellation pattern (including the unit cell bistable elements' placement), its initial diameter, and the resulting desired shape. The method used in placing the unit cell bistable elements considers the principle stress trajectories. Two different examples of shape-morphing space frames are presented herein, each starting from a cylindrical-shell space frame and morphing, one to a hyperbolic-shell space frame and the other to a spherical-shell space frame, both morphing by applying moments, which shear the cylindrical shell, and forces, which change the cylinder's radius using Poisson's effect.

摘要： A linear element with two stable points, it can be used as trust element allows for change in length. It can transform structure from one shape to another thus allowing for morphable configuration. A new model is presented herein for a linear bi-stable compliant mechanism and design guidelines for its use. The mechanism is based on the crank-slider mechanism. This model takes into account the first mode of buckling and post-buckling behavior of a compliant segment to describe the mechanism's bi-stable behavior. The kinetic and kinematic equations, derived from the Pseudo-Rigid-Body Model, were solved numerically and are represented in plots. This representation allows the generation of step-by-step design guidelines. Because different applications may have different input requirements, two different design approaches are described herein with different parameters subsets as inputs.

摘要： A prosthetic finger includes a crossed four (4) bar linkage system having a base formed by a base bar, two cross bars, and an interface bar that engages an object to be held. The base bar is fixed to an artificial finger of an amputee. A first cross bar has a first end pivotally mounted to a first end of the base bar and a second cross bar has a first end pivotally mounted to a second end of the base bar. The first cross bar has a second end pivotally mounted to a first end of the interface bar and the second cross bar has a second end pivotally mounted to a second end of the interface bar. The first and second cross bars are slideably interconnected to one another at a cross point which changes its location as the prosthesis grasps objects of differing sizes and shapes.
