Abstract: A method for providing access into a building is shown. The method includes receiving an indication that a potential building occupant is requesting access into the building. The method includes providing input data into a probabilistic model, the input data comprising current health data of the potential building occupant obtained in response to receiving the indication. The method includes analyzing, via the probabilistic model, relationships between a plurality of weighted variables within the probabilistic model to determine an entry decision for the potential building occupant, wherein each of the plurality of weighted variables are representative of subsets of the input data. The method includes, in response to the entry decision permitting the building occupant to enter the building, providing a control signal to a security system to permit access to the building for the building occupant.

Abstract: Systems and methods of operating a collaborative building network are disclosed. In one aspect, a method of operating a building management system includes acquiring, by a first computing system, data using one or more sensors of a first building of a first entity, providing, by the first computing system, a set of sharing rules for the acquired data, determining, by the first computing system by applying the set of sharing rules, whether to share the acquired data with a second computing system associated with a second building of a second entity, and providing, by the first computing system, the acquired data to the second computing system responsive to the determination.

Abstract: A system mitigates transitions among pixels a mosaic image. The system uses two balancing adjustments and an easing transition adjustment. The first balancing adjustment uses a histogram to remap the pixels in the mosaic to a normal distribution. The second balancing adjustment minimizes transitions between adjacent individual images in the mosaic based on pixels positions of edge pixels and intensity differences between edge pixels in the adjacent images. The easing transitions adjustment modifies the intensity of a target pixel as a function of a radius from the target pixel, the distance between the target pixel and a nearest neighbor pixel, and an intensity difference between the nearest neighbor pixel and a pixel adjacent to the nearest neighbor pixel. A revised mosaic image is created as a function of the first balancing adjustment, the second balancing adjustment, and the easing transition adjustment.

Abstract: Methods and systems for an extensible, universal ledger. One of the methods includes receiving at a journal manager engine a register transaction type request for a first transaction type, the journal manager engine reading and writing to a journal that stores a history of object state and of code by which object state is changed, wherein the register transaction type request is based at least in part on a template and specifies at least one action that can be performed as part of the first transaction type; writing the transaction type request to the journal including an operation definition for the first transaction type; receiving a transaction request of the first transaction type; obtaining the operation definition from the journal; executing an operation in response to the transaction request to produce a transaction result; and recording the transaction result in the journal.

Abstract: A building security system includes one or more memory devices configured to store instructions that, when executed by one or more processors, cause the one or more processors to receive multiple alerts relating to a building, the multiple alerts include alert types. The instructions further cause the one or more processors to identify a set of alert disposition options for the multiple alerts based on the alert types, and estimate probabilities of use for the set of alert disposition options. The instructions further cause the one or more processors to calculate alert disposition risk scores using the estimated probabilities of use of the set of alert disposition options, calculate alert risk scores based on a combination of the alert disposition risk scores for the set of alert disposition options of the multiple alerts, and present two or more of the multiple alerts based on the alert risk scores.

Abstract: A method includes receiving, by one or more processing circuits, risk data indicative of at least one of behavior of the users relating to the shared space or a user risk relating to a risk of one or more of the users contracting or spreading a disease, determining, by the one or more processing circuits, an accessibility limit for the shared space based on the risk data, the accessibility limit comprising at least one of an occupancy limit for the shared space or a timeframe during which the shared space is prohibited from occupancy, and generating, by the one or more processing circuits, an indicator of the accessibility limit for the shared space, the indicator providing an indication to the users of at least one of the occupancy limit or the timeframe during which the shared space is prohibited from occupancy.

Abstract: An apparatus for perfusing an organ or tissue including a perfusion circuit for perfusing the organ or tissue with liquid perfusate; and an oxygenation system for oxygenating perfusate that recirculates through the perfusion circuit. The oxygenation system includes an oxygen circuit for delivering oxygen to the liquid perfusate and an air circuit for delivering ambient air to the liquid perfusate. The air may be pumped through the oxygenation system via an air pump. The air or oxygen may be bubble through the perfusate to increase oxygen levels in the perfusate. Such supplemental oxygen may beneficial during hypothermic preservation of organs.

Abstract: A system receives digital images of a geographic location, associates each digital image with ground control points in a set of reference stereo images, and associates each digital image to each other digital image via image to image tiepoints. The system updates a geometry of each image via a bundle adjustment, and uses a prioritized stacking order to establish piecewise linear seam lines between each of the images. The system finally builds a prioritized map in a mosaic space specifying the source image pixels that are used in each region of the output mosaic, and forms the mosaic image using the prioritized map.
