  • Publication number: 20220338769
    Abstract: Apparatus and methods for mitigation and control of inflammatory responses during usage of an implantable sensor device. In one exemplary embodiment, the implantable sensor device includes a drug-eluting component configured to release a varying amount of anti-inflammatory substance(s) (such as corticosteroid) over the lifetime of the implant, such as according to a desired elution profile. In one variant, this component is also an analyte-permeable membrane used as part of a detector of the implant. Inhibition of inflammation in the tissue improves availability of analytes (such as oxygen and glucose) to the sensor in addition to reducing fibrous encapsulation. Various modifications to the elution rate, and configuration of the implant, allow optimized control over undesirable effects such as foreign body reactions (FBR) or other inflammatory responses which may reduce usable implant lifetime.

  • Patent number: 10659739
    Abstract: Projection systems and/or methods comprising a blurring element are disclosed. In one embodiment, a blurring element may comprise a first plate having a pattern on a first surface and second plate. The first plate and the second plate may comprise material having a slight difference in their respective index of refraction. In another embodiment, a blurring element may comprise a first plate having a pattern thereon and a second immersing material. The blurring element may be placed in between two modulators in a dual or multi-modulator projector system. The blurring element may be configured to give a desired shape to the light transmitted from a first modulator to a second modulator.
