  • Patent number: 12386196
    Abstract: A system creating an autostereoscopic augmented reality (AR), virtual reality (VR), or other visual display experience involving 3D images, presented to a viewer without glasses or other head-gear. The system includes a projection screen, which includes a reflective surface formed using retroreflective material. The system includes a projection assembly and a beamsplitter, which is disposed between an outlet of the projection assembly and the projection screen. The system includes a physical scenic space facing a lower side of the beamsplitter and a viewing space facing an upper side of the beamsplitter. A controller operates the projector assembly to project left and right eye images toward the projection screen. The left and right eye images are then directed to left and right eye positions so a viewer with eyes positioned at the left and right eye positions perceives a virtual object concurrently with light from the physical scenic space.

  • Patent number: 12386833
    Abstract: A system receives ETL specification for processing stream data, including a transform operation represented using a database query specification. The system generates a dataflow graph of a sequence of database queries by decomposing the database query into a first database query that generates an intermediate results table, and a second database query that receives as input the intermediate results table and outputs data used for performing the transform operation. The system executes the sequence of database queries for performing the transform operation on stream data received from the source. When receiving an incremental data set, the system determines an output change set based on the received incremental data set by traversing an execution plan and processing each operator in the execution plan, and computing a change set of a particular operator from the change sets output by the one or more other operators based on the incremental data set.

  • Patent number: 12388480
    Abstract: Techniques for selecting frequencies of operation are described. HF signals may land at the receiver node with power levels dependent upon the transmit frequency. The frequency with the highest power level at the receiver node may be selected when the receiver node is not subject to interfering. The receiver node may be unable to receive a desired signal if an interfering signal has a signal level which is higher than the desired signal. The transmitter node may select a frequency which has a receiver signal level which is higher than the interfering signal for the selected frequency. The receiver node may then receive the transmit signal at the selected frequency even when subject to interfering from the interferer node.

  • Patent number: 12387007
    Abstract: Sanitizing data can be a cumbersome task, particularly when the volume of data is large, the content is sensitive, and/or the type of sanitation requires contextual determinations. Sanitizing large amounts of data is tedious and may often require highly trained personnel with clearances and/or other qualifications. In the systems and methods of the present disclosure, language models (LMs) are used to solve these and other technical issues with tools that may allow sanitizing data easily, with high versatility, context awareness, and/or low demand for computational resources. In particular, some of the disclosed systems and methods use a first language model and a second language model (being less resource-intensive than the first language model) to generate sanitized output data with improved efficiency and accuracy. This dual-model approach ensures that sensitive information is handled appropriately while optimizing computer resource usage.

  • Patent number: 12389274
    Abstract: Systems and methods are provided for alleviating congestion of data traffic in a wireless network in a cell site. The methods determine congestion levels for respective data connections from mobile computing devices to a network through a cell tower in a cell site. The method further determines a congestion level associated with the cell site based on a weighted aggregate of varying congestion levels associated with the respective data connections in the cell site. The disclosed technology includes flow policies associated with congestion levels. The flow policies determine weights used for determining the weighted aggregate and maximum network bandwidth enforced for the respective data connections. The disclosed technology identifies data connections that consume abnormally high amount of network bandwidth and throttles with bias against data traffic associated with these data connections with heavy traffic.

  • Patent number: 12388631
    Abstract: A server and a device can conduct a secure session with (i) multiple post-quantum cryptography (PQC) key encapsulation mechanisms (KEM) and (ii) forward secrecy. The device can store a server static public key (PK.server) before establishing a secure session with the server. The device can use PK.server to encrypt a device ephemeral public key (ePK.device) into a first ciphertext. The first ciphertext can also include a device digital signature. The server can receive and decrypt the first ciphertext. The server can use the ePK.device to encrypt a server ephemeral public key (ePK.server) into a second ciphertext. The second ciphertext can also include a server digital signature. The device can receive and decrypt the second ciphertext. The device can encrypt application data into a third ciphertext using both PK.server and ePK.server. PK.server can support a first PQC algorithm and ePK.server can support a different, second PQC algorithm.

The method also includes calculating a signature at the second certificate authority based at least in part on the attribute, and calculating a hash value based on a combination of the signature calculated at the second certificate authority and a key associated with the second certificate authority. The method includes generating a cross certificate and embedding the hash value as a certificate extension within the cross certificate.

  • Patent number: 12389503
    Abstract: A correlated color temperature (CCT) of one or more luminaires is controlled by obtaining a target CCT for the one or more luminaires and obtaining a first profile associated with a first luminaire of the one or more luminaires. A first target power for a first direct-current (DC) power input of the first luminaire and a second target power for a second DC power input of the first luminaire are calculated based on the target CCT and the first profile so that the first target power and the second target power drive the first luminaire to emit light at the target CCT. A first DC power supply is controlled to deliver the first target power to the first DC power input of the first luminaire and a second DC power supply is controlled to deliver the second target power to the second DC power input of the first luminaire.
