  • Radio frequency signaling system and curable composition
    Patent number: 12228536
    Abstract: A radio frequency signaling system includes a curable coating composition configured to be cured to form a cured coating and a sensor received in the curable coating composition. The sensor includes circuitry forming an inductor-capacitor circuit. The circuitry has a maximum outer diameter of 10 ?m-2.0 mm. The circuitry is configured to generate an electromagnetic field in response to an external radio frequency signal. A container configured to be monitored by a radio frequency signaling system is also provided. The container includes: a container body having an outer surface and an inner surface; a cured coating on the inner surface and/or the outer surface of the container body; and a sensor positioned in the cured coating configured to detect absorption of a fluid contained in the container body by the cured coating.

  • Retractable storage devices
    Patent number: 11589679
    Abstract: A retractable storage device for an armrest of a chair, including a vertically extending arm assembly including a first distal end and a second distal end, a horizontally extending arm assembly including a first distal end and a second distal end, a middle connector, and a storage container. The second distal end of the vertically extending arm assembly is pivotally secured to the middle connector, and the first distal end of the horizontally extending arm assembly is pivotally secured to the middle connector. The retractable storage device is moveable between a stowed position and a raised position. The storage container is coupled to the second distal end of the horizontally extending arm assembly, where the storage container is stowed beneath the armrest when the retractable storage device is moved to the stowed position.
