Abstract: In a mobile computerized device, a method for generating visually coherent lighting for mobile augmented reality comprises capturing a set of near-field observations and a set of far-field observations of an environment; generating an environment map based upon the set of near-field observations of the environment and the set of far-field observations of the environment; applying the environment map to a virtual object to render a visually-coherent virtual object; and displaying an image of the environment and the visually-coherent virtual object within the environment on a display of the mobile computerized device.

Abstract: A rechargeable lithium-ion (Li-ion) battery employs a low temperature approach to battery manufacturing that forms charge material from kinetic energy of high velocity particles impelled into an aggregation such that bombardment of the particles against other particles in the aggregation forms a charge conveying structure. High velocity bombardment from a carrier gas nozzle accumulates an active charge material in a layered arrangement for the finished battery. Preparation of the particles, such as by ball milling or spraydrying, arranges particle agglomerations. The particle agglomerations, when impelled against other agglomerations or a current collector, forms a layer of cathodic, anodic or electrolytic battery material. The metallic binder conveys charge for mitigating or eliminating a need for a planar current collector underlying the sprayed layer. The resulting layers are suitable for battery operation, and are manufactured in an absence of any solvent drying or disposal.

Abstract: A 6-axis robot performs autonomous complex assembly based on a task-independent approach by directing a robotic member on a first approach trajectory for placement of a grasped object, and determining that placement along the first trajectory is blocked. The robotic member has an end-effector at a distal end configured for compressively grasping the object. Blockage is determined by force and torque sensing encountered by the end effector prior to attaining an intended pose or position. The robot identifies a second, alternate approach trajectory for placement of the grasped object based on a probability of success of the second approach trajectory, resulting from considering probabilities of candidate trajectories or positions. The robotic member continues iterative placement based on successive, alternate trajectories until placement is achieved. The robot attempts a successive placement around localized positions/trajectories in response to increased probabilities and decreased distance/error from the desired pose.

Abstract: A delayed release device for a buoy engaged with an underwater lobster trap operates with a first magnet securing a buoy, such that the buoy is tethered to a deployed lobster trap submerged in lobster harvesting regions of the ocean. A second magnet secures the first magnet based on a magnetic field, and a displacement actuator is in communication with the second magnet for retracting the magnet in response to a predetermined condition. Based on the condition, such as a time delay, the actuator moves the second magnet distal from the first magnet for releasing the buoy when the distance reduces the magnetic field sufficiently. The actuator may include a drive screw having a threaded engagement with the second magnet, such that the drive screw is responsive to rotation for retracting the second magnet.

Abstract: Method and apparatus are provided for efficient metal distillation, and for related primary product process. Vertically stacked and gravity-driven evaporators and condensers are employed to distill metals, such metals having different volatilities. A multiple-effect thermal system of magnesium and other volatile metals is used to efficiently distill and separate metals from multiple metal alloys.

Abstract: A robotically driven OCT scanning and imaging system provides a 3-dimensional (3D) image rendering based on a 2-dimensional (2D) surface traversal of a Region of Interest (ROI) for immediate depiction of tissue health with an accuracy and portability not available with conventional imaging approaches. A comprehensive scan over the surface of the ROI ensures complete coverage, and a signal indicative of attenuation of the optical scan indicates penetration of the OCT stimulus. The received signal for each location is aggregated, or “stitched” together with the signal received from adjacent locations to provide a full mapping of the scanned region, and rendered as a color or shading map for showing anomalies or sudden variances in tissue health.
