Abstract: An extensible platform-as-a-service (PaaS) system is used during the software development lifecycle (SDLC) processes of an application. The system facilitates the process of getting security approval for the application. The system allows developers to use software bundles including software modules that are pre-approved. The system allows a developer to customize one or more software modules of the software bundle if necessary. The system monitors the development of the application to check if the developer customizes any software module to use a configuration that is not pre-approved. The system automatically generates a report noting the customization to the software module and requests the security team to review the modified configuration for security approval.

Abstract: Systems and methods are disclosed for determining authenticity of a resource system. The method includes receiving a dataset that includes a first subset and a second subset associated with a first resource system; down-sampling the first subset but not the second subset; generating a first feature for a machine learning model based on the down-sampled first subset; generating a second feature for the machine learning model based on the second subset; generating, via input of at least one of the first feature or the second feature into the machine learning model that is trained to output a fraudulent measure, one or more data objects indicative of validating the fraudulent measure; and initiating performance of one or more prediction-based actions in response to the generating.

Abstract: A tracking device can be reconfigured after an amount of operation to preserve the battery capacity of the tracking device and to ensure that the tracking device can be operated for a pre-determined threshold period of time. The tracking device can provide diagnostic information representative of a state of the tracking device, such as a current power capacity of the tracking device's battery, to a mobile device within a threshold proximity of the tracking device. The mobile device can then provide the diagnostic information to a tracking server, which in turn can provide reconfiguration instructions to the mobile device. The mobile device can then pass on the reconfiguration instructions to the tracking device, in response to which the tracking device can reconfigure itself.

Abstract: Devices, systems and methods for providing push-to-talk (PTT) session participants control of a PTT session are provided. An example method may receive, from at least one computing device of a respective at least one PTT session participant, a control request for control of the PTT session. Providing control based on a control request may include designating the PTT session participant request as a transmitter of communications, and designating remaining PTT session participants as receivers of communications unable to transmit communications. The method may generate a control queue to queue PTT session participants requesting control of the PTT session, adding PTT session participants to the control queue based on when the control request is received. Providing control may include designating the PTT session participant positioned first in the control queue as the transmitter of communications, and removing the PTT session participant positioned first in the control queue from the control queue.

Abstract: Techniques for dynamic data validation are disclosed herein. An example computer-implemented method includes receiving entity data associated with an entity, the entity data including locations of the entity at respective times. The method further includes determining, by executing a dynamic period algorithm, periods based on the entity data; and applying a machine learning (ML) model to the entity data and the periods. Applying the ML model includes determining, for at least one period, one or more confidence values associated with each location at the respective times included in the period based on (i) a frequency associated with each location and (ii) a period distance value relating a current time to the period. The ML model also outputs a ranking for each location included in the period based on the one or more confidence values. The method further includes generating a data object indicating one or more of the ranked locations.

Abstract: A system performs a method for characterizing passage of a patient fluid through a conduit. The method includes quantifying flow of fluidic content through a conduit, where the fluidic content includes a patient fluid, estimating a concentration of a fluid component of the patient fluid in the fluidic content, and characterizing passage of the patient fluid loss through the conduit based on the quantified flow and the concentration of the fluid component. At least one of the quantified flow or the concentration of the fluid component is based on sensor data from a sensor arrangement coupled to the conduit. Other apparatus and methods are also described.

Abstract: A head-mounted device HMD for use in the surgical environment includes an exterior-facing display that is configured to present content. Such content can include human-readable, visual, graphical, or video content. The content can be presented to inform others of surgically relevant content. In some cases, the content includes a trackable graphic that is detectable by a remote camera source, e.g., for tracking the HMD. The content displayed on the exterior-facing display can be dynamically generated or modified based on numerous sources or detected events.

Abstract: A tracking system can provide intervention notifications to a user to notify the user that a tracking device is potentially lost or is in a predicted state. The tracking system may notify the user that a tracking device is potentially lost or in a predicted state based on a number of factors, including: a proximity of a tracking device to other tracking devices or a user's mobile device, a movement of a tracking device to more than a threshold distance away from a mobile device or other tracking devices, a location of a tracking device relative to a geographic location or to geographic boundaries, a usage or movement behavior of the tracking device, a usage or movement behavior of a user or owner of a tracking device, information received from an external source, or information received from sensors within the tracking device or a user's mobile.

Abstract: Extended reality systems and methods for use in a surgical procedure involve a head-mounted device (HMD) comprising an HMD display positionable in front of a user's eyes and a sensing system to sense control inputs of the user. Controller(s) coupled to the HMD receive control inputs from the sensing system to establish a pose of a view coordinate system in which to present a virtual object (e.g., a virtual information panel) related to the surgical procedure. The pose can be established using a virtual alignment guide. The controller(s) define the view coordinate system relative to a world coordinate system after the pose of the view coordinate system is established. The controller(s) recognize surgical information, and in response, automatically present the virtual object on the HMD display combined with a real-world view and at a predetermined position and orientation within the view coordinate system.

Abstract: A machine accesses a first image captured prior to initiation of a procedure, where the first image depicts a set of instruments, as well as a second image captured after initiation of the procedure, where the second image depicts a proper subset of the set of instruments depicted in the first image. From the first and second images, the machine may determine that an instrument among the set of instruments depicted in the first image is not depicted among the proper subset of the set of instruments in the second image, and then cause presentation of a notification that indicates the instrument not depicted in the second image is missing. Alternatively, or additionally, the machine may determine whether an instrument among the set of instruments was used in the procedure, and then cause presentation of a notification that indicates whether the instrument was used in the procedure.

Abstract: Systems and methods for quantifying blood loss with a surgical sponge management system. A data reader detects a tag of the surgical sponge, and one or more processors identify a sponge type of the surgical sponge based on a unique identifier. A presentation window is displayed on a user interface with dimensions of the presentation window based on the identified sponge type. The processor(s) determine whether characteristics of the surgical sponge satisfy acceptance criteria based on the identified type of the surgical sponge. The acceptance criteria may include sponge presence, folded sponge, partial sponge, presentation distance, correct sponge, moving sponge, mask validation, and sponge supervision. An optical sensor captures a color image of the surgical sponge once the characteristics satisfy the acceptance criteria. A volume of the blood or blood component on the surgical sponge is estimated based on the color image, and displayed on a user interface.

Abstract: A lost tracking device associated with a tracking system can be located by leveraging one or more community members by inviting these members to join a search party. Search party criteria can be identified and candidate search party members can be selected and invited based on the search party criteria. When invited candidate search party members accept the invitations, they are added to the search party. A last known location of the tracking device can be provided to the search party members, and the search party can remain in effect until the lost tracking device is located. The location of the lost tracking device is provided to the tracking system, which forwards it to the owner of the lost tracking device. A reward can be provided by the owner of the lost tracking device to the tracking system, which releases the reward to the search party member that located the lost tracking device.
