(54) Title: SYSTEMS AND METHODS THAT IMPROVE ALIGNMENT OF A ROBOTIC ARM TO AN OBJECT (57) : Systems and methods that improve alignment of a robotic 100 Computer 110 arm to an object or parts of the object. Sensors sense a 3D protrusion on the object and a salient regular surface to which the 3D protrusion attaches. A method infers, based on a known geometry of the object, a component of the object that is next to the 3D protrusion and not detectable with the sensors. The robotic arm moves, based on a location of the 3D protrusion and a location of the component, with respect to the component.

A formulation for forming a shape memory polymer is disclosed. The formulation comprises an acrylate monomer such as tert-butyl acrylate or tert-butyl methacrylate, a cross-linker such as di(ethylene glycol) diacrylate which forms cross-links with the acrylate monomer, a photoinitiator such as BAPO which initializes the cross-linking upon exposure to light and a photoabsorber for controlling the rate of cross-linking. The concentration of the photoabsorber is from 0.1 -10 wt.% of the formulation. A method of forming the shape memory polymer, and a device comprising the polymer such as a suture, stent or a dental aligner is also disclosed.

A conductive carbonaceous fiber is provided, comprising a carbonaceous material obtained from carbonizing an electrospun fiber wherein said fiber comprises at least one conductive metal precursor. The electrospun fibers can be formed into fibrous mats during spinning, stabilization and carbonization that are conductive materials which can be used to make stretchable conductors for flexible electronic devices. The invention relates also to the process for making the fibers, corresponding elastomeric fibrous mesh/polymer composites as well as use of these composites for making stretchable electrical conductors. The obtainable elastomeric composite films (with a thickness in the range of 0.8 to 1.5 mm) exhibit good electrical conductivity and excellent electromechanical stability under mechanical deformations (e.g. elongating, twisting and bending). The scalable fabrication process and low-cost precursors make the elastic electrospun carbon fibers/polymer composite conductors promising materials for applications in flexible electronic devices, displays, sensors, wearable conducting clothes, implantable medical devices, etc.
