  • Publication number: 20250057495
    Abstract: A system and method for performing a dual energy subtraction imaging process on a fixed or mobile fluoroscopy imaging system for pulmonary imaging applications is provided. The dual energy subtraction image processing system includes a processor configured to operate a radiation source of a fluoroscopy imaging system in a pulsed manner to obtain a number of high energy (HE) frames, to form an HE image from the number of HE frames, to operate the radiation source of the fluoroscopy imaging system in a continuous manner to obtain a number of low energy (LE) frames, to form an LE image from the LE frames, and to employ the HE image and the LE image in a dual energy subtraction imaging process to output a number of enhanced contrast images. The processor is also configured to operate the detector in continuous manner to obtain the HE frames and the LE frames.

  • Patent number: 12207086
    Abstract: Authenticating a mobile user device with a mobile network operator in advance of an MNO authentication request from the mobile user device can be done by a satellite network sending an authentication request to the MNO system, obtaining a set of authentication vectors related to the mobile user device, storing them into a proxy home location register, receiving the MNO authentication request from the mobile user device, generating an authentication request response based on the authentication vectors, sending the authentication request response to the mobile user device, receiving an authentication response including a received signed response, comparing the received signed response with the stored signed response, and if the received signed response and stored signed response match, deem that to be a successful authentication, add an MNO location update message to a request queue and forward the MNO location update message to the MNO system over the channel when available.

  • Patent number: 11991254
    Abstract: Techniques for an ontology-based approach for modeling service dependencies in a provider network. The approach is flexible and extensible to different provider network SOA systems and not limited to a particular provider network or a particular SOA system. The approach can be used to model an entire SOA system or selected portion thereof and from different perspectives. In some examples, the approach uses an ontology represented using a Web Ontology Language (OWL). In some examples, the ontology is used to identify service dependencies and relationships in a knowledge base that is populated based on operational data collected in the provider network environment.

  • Patent number: 11958914
    Abstract: Disclosed are compositions and methods for targeted treatment of glioblastoma multiforme (GBM). In particular, chimeric antigen receptor (CAR) polypeptides are disclosed that can be used with adoptive cell transfer to target and kill Glioblastoma Stem Cells (GSCs). Also disclosed are immune effector cells, such as T cells or Natural Killer (NK) cells, that are engineered to express these CARs. Therefore, also disclosed are methods of providing an anti-tumor immunity in a subject with Glioblastoma Stem Cells (GSCs) that involves adoptive transfer of the disclosed immune effector cells engineered to express the disclosed CARs.

  • Publication number: 20230179990
    Abstract: A telecommunications receiver is adapted to communicate with mobile devices that operate according to a protocol where the telecommunications receiver operates outside of expected ranges for the protocol but modifies its communications with mobile devices to appear to those mobile devices as being within the expected ranges. To determine what modifications to make to transmissions, the telecommunication receiver processes signals from mobile devices to determine where a communications channel is relative to the expected ranges and uses that information to modify transmissions to mobile devices. The expected ranges might relate to maximum distance between telecommunications receiver and a mobile device, maximum relative velocity, power etc.
