  • Publication number: 20220193444
    Abstract: A phototherapy system having sensor(s) for detecting parameters associated with light generation by a light source and circuitry for modulating the light source based on the detected parameters. Also, a phototherapy system having a light guide interfacing with a light source at a connection point, an ambient light sensor, a connector light sensor for detecting (at the connection point) ambient light received by a light emitting pad that is directed into the light guide, and circuitry for determining whether the light guide is correctly connected to the light source based on a difference between the output of the ambient light source and the connector light sensor. Further, a phototherapy system including a light emitting pad having an identification tag and circuitry that modulates a light source based on the identification tag. Additionally, a phototherapy system including a casing encapsulating multiple light emitters and a light emitting pad.

  • Publication number: 20200406056
    Abstract: A phototherapy device for delivering light emitted by a light source to an infant. The phototherapy device includes two or more light pads configured to be optically connected to a light source via a connector. Light emitted by the light source is received by the connector and propagated through the connector to the light pads. The phototherapy device also includes a flexible garment configured to maintain the position of the pads on a front and back of an infant.

  • Publication number: 20200163737
    Abstract: An ocular lighting assembly (10) including an anchor (16) and a plurality of light guides (14). The anchor is configured to mount to a surface of an eye (30) and to maintain the position of the plurality of discrete light guides. The plurality of light guides are arranged to guide light from a light source into the interior of the eye.

  • Patent number: 10010696
    Abstract: Various equipment and methods associated with providing a concentrated product gas are provided. In one embodiment, the equipment includes an input device first and second sieve tanks, a variable restrictor, and a controller. In one embodiment, the method includes: a) selecting a desired output setting for the concentrated product gas from a plurality of output settings, b) separating one or more adsorbable components from a pressurized source gaseous mixture via first and second sieve tanks in alternating and opposing pressurization and purging cycles to form the concentrated product gas, and c) selectively controlling a variable restrictor based at least in part on the desired output setting to selectively provide flow between the first and second sieve tanks such that the flow for at least one output setting is different from the flow for at least one other output setting in relation to corresponding pressurization cycles.
