  • Publication number: 20240115993
    Abstract: Systems and methods for providing regeneration heat to a sorbent material and subsequently recovering a significant portion of the heat are provided. The systems and methods are useful, for example, for energy-efficient direct capture of carbon dioxide (CO2) from the atmosphere or flue gases. The systems and methods include introducing steam generated by an evaporator into a reactor of the system to directly heat sorbent material in the reactor and to purge desorbed CO2 from the reactor using the steam. Water condensing within the reactor is drained and returned to the evaporator. The purged steam and CO2 from the reactor are directed to a vapor re-compressor to lift their temperature and then to a condenser or re-boiler where the water is condensed and separated from the CO2 and latent heat transferred to the cooling water is recovered, optionally via use of a jet ejector.

  • Patent number: 11586288
    Abstract: A controller for sensing interior motion includes a sensor structure having transmitting conductors and receiving conductors. The controller comprises circuitry to drive and sense signals on interacting pairs of conductors (the transmitting conductor or receiving conductor can act as the drive side, or as the sense side). Signals are processed to analyze changes in measured signal and analyzed to determine interior movement. When the controller is deployed proximate to human skin, movement of muscles, tendons and bones within the skin are reflected in the measured signals.

  • Patent number: 11287254
    Abstract: A sensing system is embedded into a fabric or material that conforms to a portion of a user's body. The fabric or material has transmitting antennas and receiving antennas placed thereon. Movement of the fabric or material with the transmitting and receiving antennas placed thereon are able to measure the changes in the signals received by the receiving antennas. Measurement of the changes are used to determine movement of and position of parts of the body within and/or distal to the fabric or material by determining localized pressure deformation to reconstruct volumetric changes.

  • Patent number: 10990190
    Abstract: Disclosed is a touch-sensitive controller system employing a controller comprising a plurality of separate FMT sensor patterns adapted to detect a variety positions of the human hand. The controller system outputs both touch events as well as data reflective of the hand interaction with the controller. The FMT sensors may be driven by a common signal generator, and can look at body-generate crosstalk to aid in understanding the position, orientation and grip of a hand on the controller. In an embodiment, signal injection can supplement FMT sensor data. Fusion among the data transmitted and received by the plurality of FMT sensors and additional injected signals may provide improved fidelity in both touch and hand modeling.

  • Patent number: 10928180
    Abstract: A controller for sensing deformation including a sensor structure having a deformable conductor and another conductor (which may also be deformable). The deformable conductor may be made out of a flexible non-fluid material (e.g., rubber) or a conductive fluid. The deformable conductor may be deformed by the deformation of the sensor structure or by other forces. The sensor comprises circuitry to drive and sense signals on interacting pairs of conductors (the deformable conductor or the other conductor can act as the drive side, or as the sense side). Sense signals are processed to analyze deformation of the deformable conductor, and deformation of the sensor structure. Where the sensor is deployed proximate to human skin, deformation and changes in deformation may be used to correlate or infer a body position, movement or pose.
