  • Publication number: 20260147902
    Abstract: This disclosure principally describes a framework for providing endpoint encryption-based file protection at the system-wide level on client devices. For instance, this disclosure describes a file protection system that utilizes a holistic, system-wide security approach to provide trusted container solutions for protected files accessed on a client device. For example, the file protection system creates and binds security information metadata to protected file content at an endpoint device, which helps enforce the access rights and permissions of a file at a system-wide level. In addition, the security information metadata remains bound to the file even if the protected content is modified. Furthermore, if the file is shared with another client device, the security information metadata within the file enables the file protection system to maintain the initially set protections and access rights on the other client devices.

  • Patent number: 12638849
    Abstract: A tracking target position estimation unit and a tracking target search unit that searches for a tracking target are included. The tracking target search unit calculates one or more search routes connecting a current position of the mobile device and a position where the tracking target can exist, generates a search route list in which the calculated one or more search routes are arranged from the top in order of proximity to a tracking target estimated position, and selects a search route in order from the top of the generated search route list, and moves the mobile device according to the selected search route to search for the tracking target. It is determined whether or not the tracking target has been detected based on an image captured by a camera mounted on the mobile device, and in a case where the tracking target has been detected, tracking processing is resumed.

  • Patent number: 12634759
    Abstract: Several policies are trained for determining communication parameters used by mobile devices in selecting a cell of a first communication network to operate on. The several policies form a policy bank. By adjusting the communication parameters, load balancing among cells of the first communication network is achieved. A policy selector is trained so that a target communication network, different than the first communication network, can be load balanced. The policy selector selects a policy from the policy bank for the target communication network. The target communication network applies the policy and the load is balanced on the target communication network. Improved load balancing leads to a reduction of the number of base stations needed in the target communication network.

  • Patent number: 12632148
    Abstract: This document describes systems and techniques directed at mitigating display diffraction flares for under-display sensing. In aspects, an equation may be derived that models the effects of a display in producing a diffraction phenomenon at an image plane of a sensing region for an under-display light-sensing device. The equation may be used to determine an arrangement (e.g., an optimized arrangement) of components (e.g., sub-pixels) within the display that minimizes a diffraction efficiency for at least one diffraction order and, thereby, mitigates an intensity and/or a prevalence of optical artifacts in light-sensing data. In implementations, an image intensity point-spread-function is utilized to calculate diffraction efficiencies for respective diffraction orders (e.g., the lowest diffraction orders, the diffraction orders with the greatest brightness).

  • Publication number: 20260134312
    Abstract: A system and a method are disclosed for a tool that generates a provider score corresponding to a predicted performance of a provider based on data of claims involving the provider. For a given claim, the tool provides the data as input into a supervised machine learning model and receives as output from the supervised machine learning model a predicted performance of the claim. The tool also inputs the data of the claim into an unsupervised machine learning model that is selected based on a stage of claim processing that the claim belongs to and receives as output from the unsupervised machine learning model an identification of a cluster of candidate claims to which the claim belongs. The tool combines the outputs of the supervised machine learning model and the unsupervised machine learning model to generate the provider score.

  • Patent number: 12626211
    Abstract: Systems and methods of route optimization are disclosed. An adjustment engine receives a plurality of driver-trip pairs each including a driver selected from a plurality of drivers and a trip selected from a plurality of trips and determines a weight for each of the driver-trip pairs. The weight is determined based on at least one driver-trip feature, at least one driver feature, and at least one trip feature. A route optimization engine selects a set of optimal driver-trip pairs based on a bipartite matching process including the weight for each of the driver trip pairs. The set of optimal driver-trip pairs minimizes total estimated time of arrival to a pickup location for each trip in the plurality of trips. Trip data is transmitted to a corresponding device associated with a corresponding driver paired with each trip in the set of optimal driver-trip pairs.

  • Patent number: 12607702
    Abstract: Within several applications the ability to localize an individual within an environment is beneficial. However, existing indoor localization approaches depend upon at least one of two assumptions. First, the subject(s) localization is achieved by localizing a wireless device carried by the subject and second, wireless fingerprints are established for the localization via a site survey being performed before a system can actually localize the subject(s). However, in many application scenarios, neither of the above two assumptions are true, namely that the user is not carrying an active wireless device or that the site has been surveyed. Accordingly, embodiments of the invention provide for subject localization by a dynamic calibration of wireless signals between a receiver and a transmitter, where neither the receiver or transmitter are associated with an electronic device carried or worn by the subject.
