  • Patent number: 12498517
    Abstract: A terminated hollow-core optical fiber includes a capillary, a hollow-core optical fiber including a structured cladding, and an endcap. A first end of the hollow-core optical fiber terminates inside the capillary a non-zero distance away from a first end face of the capillary. The hollow-core optical fiber is adhered to the capillary at a second end face of the capillary where the hollow-core optical fiber extends out of the capillary. The endcap is fused to the first end face of the capillary. The endcap has a larger diameter than the first end of the hollow-core optical fiber. This termination scheme does not require fusing the hollow-core fiber itself to the endcap or any other part. Therefore, this termination scheme is applicable to hollow-core fibers with a structured cladding that cannot tolerate the temperatures associated with fusing the hollow-core fiber to another part.

  • Publication number: 20240220540
    Abstract: A system and method for predicting stats for different destinations is provided. The system and method can include receiving a dataset of stats in a spatial format and a request for stats in a geographical area. The system and method can include determining a grid of cells based on the geographical area, determining an origin point in each cell in the grid of cell, determining a graph based on the grid of cells, determining a proportion of the stat to assign to each node, edge or both in the graph in the geographical area based on an overlap between the dataset of stats and the graph, and determining a total for the stat for the geographical area.

  • Patent number: 11407969
    Abstract: The present invention relates in part to devices, systems, and methods for the production and characterization of engineered tissue constructs. The devices and methods generate decellularized tissue constructs that can be recellularized using donor cells for high-throughput studies of organ physiology, and/or organ pathology. The devices and methods can be used with the systems to mechanically and electrically stimulate the engineered tissue constructs under culture or physiological conditions to detect and assess the presence and degree of any organ pathologies.

  • Patent number: 10996411
    Abstract: The invention relates to an optical assembly (100) comprising a first optical fiber (101) propagating coherent light in a predetermined direction (P) into an input end (110) of the optical assembly (100), said optical fiber having a core and a cladding; a heat sink (111) surrounding the optical fiber (101) at the input end (110); and a lens (120) arranged after the heat sink (111) in the propagating direction (P). The optical assembly (100) further comprises a filter (130) arranged after the lens (120), wherein the filter (130) has a reflective surface (131) arranged to transmit light having one or more desired wavelengths and to reflect one or more undesired wavelengths back through the lens (120). The invention further relates to a method for separating desired and undesired wavelengths.
