  • Publication number: 20240133867
    Abstract: A breath capture and analysis system includes a breath inlet for capturing a user's breath. The breath is drawn into the system and retained for analysis. The system includes a membrane that allows volatile organic compounds contained in the breath to pass therethrough. The volatile organic compounds pass into a vacuum chamber that includes a residual gas analyzer that is configured to analyze the volatile organic compounds. The analyzed breath is then vacated from the system.

  • Patent number: 11960909
    Abstract: A method and system of providing users with session-specific layouts during access of an application based on contextual data. The system identifies contextual data for each application access session and associates the contextual data with a particular in-app activity. The in-app activity corresponds to a task that is typically performed by the first user when the specific contextual data is detected. The contextual data can include location data, time and date data, and device type data.

  • Patent number: 11933864
    Abstract: A system and method of effectively measuring a change in a gradient of a magnetic field. The systems include a first magnet and a second magnet mechanically coupled together and aligned along a polarization axis. The first magnet and the second magnet are positioned such that a pair of like magnetic poles of the first magnet and the second magnet face in opposite directions. Further, the first magnet and the second magnet are configured to move along the polarization axis in response to a magnetic field. A sensing system is configured to measure a change in a gradient of the magnetic field based on the movement of the first magnet and second magnet along the polarization axis in response to the magnetic field.

  • Patent number: 11931302
    Abstract: Optionally, a plurality of spacers 228 is arranged between the planar surface 120 of the interfacing arrangement 114 (or the top horizontal arm) and the seat arrangement 102, for permanently raising the seat arrangement 102 with respect to the interfacing arrangement 114. The spacers 228 can be implemented as rectangular or cylindrical solid blocks that can be fabricated from plastics materials, metals, metal alloys, polymers, ceramics, wood, composites and so forth. The spacers 228 can be fixed between the seat arrangement 102 and the top planar surface 120 of the top horizontal arm of the interfacing arrangement 114 such that height of the seat arrangement 102 relative to the footrest arrangement 116 is raised. For example, a plurality of metallic spacers is fixed between the seat arrangement 102 and the interface arrangement by a technician such as by welding the metallic spacers between the seat arrangement 102 and the interface arrangement.
