  • Patent number: 11209138
    Abstract: A lighting fixture appears as a skylight and is referred to as a skylight fixture. The skylight fixture has a sky-resembling assembly and a plurality of sun-resembling assemblies. The sky-resembling assembly has a sky-resembling optical assembly and a sky-specific light source, wherein light from the sky-specific light source exits a planar interior surface of the sky-resembling light optical assembly as skylight light. The plurality of sun-resembling assemblies are arranged adjacent one another and extend downward from a periphery of the sky-resembling assembly. Each of the plurality of sun-resembling assemblies has a sun-resembling optical assembly and a sun-specific light source, wherein light from the sun-specific light source exits a planar interior surface of the sun-resembling optical assembly as sunlight light.

  • Publication number: 20210228715
    Abstract: In some embodiments, the methods involve the use of a combination of at least two of the following: an inhibitor of indoleamine-2,3-dioxygenase (IDO), an inhibitor of the PD-L1/PD-1 pathway, an inhibitor of CTLA-4, an inhibitor of CD25, or IL-7. The inventors particularly observed a major synergistic effect of combining anti-CTLA-4 with either an IDO inhibitor, with anti-PD-L1 mAb, or with CD-25 depletion. Such combinations have been found to demonstrate a synergistic effect in treating cancer and tumors, for example by reducing tumor size, increasing the percentage of antigen-specific T cells, and increasing T cell function.

  • Patent number: 10973581
    Abstract: Disclosed are systems and methods for obtaining a structured light reconstruction using a hybrid spatio-temporal pattern sequence projected on a surface. The method includes projecting a structured light pattern, such as a binary de Bruijn sequence, onto a 3D surface and acquiring an image set of at least a portion of this projected sequence with a camera system, and projecting a binary edge detection pattern onto the portion of the surface and acquiring an image set of the same portion of the projected binary pattern. The acquired image set of the binary pattern is processed to determine edge locations therein, and then employed to identify the locations of pattern edges within the acquired image set of the structured light pattern. The detected edges of the structured light pattern images are employed to decode the structured light pattern and calculate a disparity map, which is used to reconstruct the 3D surface.

  • Publication number: 20210093394
    Abstract: Devices and systems are provided for tracking a position and orientation of a handheld implement, such that the handheld implement may be trackable with an overhead tracking system. A support member secures one or more markers relative to a longitudinal portion of the handheld implement, and a marker plane containing the markers is orientated an angle relative to a longitudinal axis of the longitudinal portion. A marker assembly may include a support member for supporting the markers, and a connector for removably attaching the marker assembly to one or more handheld implements. The marker assembly may be configured to be removably attachable to a plurality of connection adapters, where each connection adapter is further connectable to a handheld implement, optionally at a calibrated position, such that a single connection adapter can be optionally employed to track a plurality of handheld implements. The handheld implement may be a medical instrument.

  • Publication number: 20210065411
    Abstract: The present disclosure relates to the generation of partial surface models from volumetric datasets for subsequent registration of such partial surface models to surface topology datasets. Specifically, given an object that is imaged using surface topology imaging and another volumetric modality, the volumetric dataset is processed in combination with an approach viewpoint to generate one or more partial surfaces of the object that will be visible to the surface topology imaging system. This procedure can eliminate internal structures from the surfaces generated from volumetric datasets, thus increases the similarity of the dataset between the two different modalities, enabling improved and quicker registration.

  • Publication number: 20200100847
    Abstract: Devices and methods are provide for facilitating registration and calibration of surface imaging systems. Tracking marker support structures are described that include one or more fiducial reference markers, where the tracking marker support structures are configured to be removably and securely attached to a skeletal region of a patient. Methods are provided in which a tracking marker support structure is attached to a skeletal region in a pre-selected orientation, thereby establishing an intraoperative reference direction associated with the intraoperative position of the patient, which is employed for guiding the initial registration between intraoperatively acquired surface data and volumetric image data. In other example embodiments, the tracking marker support structure may be employed for assessing the validity of a calibration transformation between a tracking system and a surface imaging system.
