Abstract: A bio-oil reactor leverages chemically recalcitrant lignocellulosic biomass using a moderate temperature molten-salt based process to unlock hydrocarbon content having the potential to substantially supplement demand for petroleum based fuels and chemicals. Bio-oil is a precursor to production of other chemicals and hydrocarbons, and can be refined as an effective replacement to conventional petroleum products and fossil fuels. A disclosed approach employs Molten-Salt Pyrolysis (MSP), for the efficient and economical production of such precursor chemicals directly from whole biomass under moderate conditions (˜400° C., 1 atm.). Lignocellulosic biomass, freely available in renewable wood and plant products, undergoes a moderate temperature heating process in a eutectic molten salt mixture to generate a condensable vapor of the precursor or platform chemicals.

Abstract: A robotic sensing and touch apparatus detects gradual deformations in a resilient surface, in contrast to conventional rigid member displacement. Hall effect sensors coupled to rare-earth magnets in a deformable base allow sensing of surface curvature and compression against grasped objects. The deformable base, such as a silicone mold or other resilient encapsulation, fixes a magnetic source and an opposed Hall effect sensor. Calibration of a received magnetic field is defined by a sensor element voltage in an “at rest” (undeformed) state, and at successive degrees of deformation resulting from compression of the deformable base that draws the magnet in different orientations relative to the Hall effect sensor. An array of magnet and sensor element pairs allows relative sensing over an area for detecting curvature of a translated or articulated member, or engagement with a curved surface.

Abstract: An indoor localization system uses Visual Simultaneous Localization and Mapping (VSLAM) aided by gyroscope sensor information. Indoor environments pose several challenges which could cause a vision only system to fail due to tracking errors. Investigation revealed significant feature loss in a vision only system when traversing plain walls, windows and staircases. However, the addition of a gyroscope helps in handling such difficult conditions by providing additional rotational information. A portable system consisting of an Inertial Measurement Unit (IMU) and a stereo camera has been developed for indoor mapping. The images and gyroscope rates acquired by the system are stored and post-processed using Gyroscope Assisted Scalable Visual Simultaneous Localization and Mapping Algorithm.

Abstract: Extraction of rare earths from end-of-use machinery having rare earth magnets provides a closed-loop process towards recycling rare earths from comingled devices having embedded magnets such as motors, generators and disk drives. A low temperature process selectively leaches the magnet material from mixed scrap containing shredded fragments of the machinery which includes other metals such as steel and copper. Filtration separates the other metals from the leached, dissolved magnet material, which is precipitated by oxalic acid to form oxalates in powder form, suitable for use in production of new rare earth magnetic material. Leaching acid, such as HCl (hydrochloric acid), is recoverable via pyrohydrolysis, and redirected back to the leaching step for completing the closed-loop aspect.
