Abstract: A computing system can perform computer-vision-based operations to create a vision-based user environment. The system can process an image stream and identify a computer vision character of a vision alphabet in the image stream. The vision alphabet includes a collection of computer vision characters, with each computer vision character having a distinctive characteristic identifiable by computer vision. The system can process an image of the video stream to provide to a user device a function associated with the identified computer vision character, the processing including to make a bounded space within the video stream corresponding to the identified computer vision character interactive on the user device. The system can provide the function in response to interaction with the bounded space at the user device. The system can provide a processed image to the user device, or simply provide functionality for a received stream.

Abstract: Techniques are disclosed for monitoring a patient for the occurrence of a cardiac arrhythmia. A computing system generates sample probability values by applying a machine learning model to sample patient data. The machine learning model determines a respective probability value that indicates a probability that the cardiac arrhythmia occurred during each respective temporal window. The computing system outputs a user interface comprising graphical data based on the sample probability values and receives, via the user interface, an indication of user input to select a probability threshold for a patient. The computing system receives patient data for the patient and applies the machine learning model to the patient data to determine a current probability value. In response to the determination that the current probability exceeds the probability threshold for the patient, the computing system generates an alert indicating the patient has likely experienced the occurrence of the cardiac arrhythmia.

Abstract: Prefix compression routes provided via exact match using redirection and mirroring Forwarding Equivalence Class entries in hardware. In a network device, a first table is stored having a first entry, a second table is stored having a second entry, and a third table is stored having a third entry including routing information for routing data packets. The first entry references a first memory location in the second table, the second memory location stores the second entry, and the second entry referencing a second memory location in the third table. A data packet is received, and the first entry is accessed based on a destination address of the data packet. Routing information is obtained as a result of accessing the first entry. The data packet is sent by the network device according to the routing information.

Abstract: Systems of the present disclosure reduce end-to-end latency within a signal path of a wireless audio system by using a host synchronized link that bases synchronization on a start of frame signal from the host. The host synchronized link may be included in a transmitter. The use of the host-issued start of frame signal (e.g., from a USB controller) enables bypassing or omission of a sample rate converter. By bypassing the sample rate converter, the latency associated with the sample rate converter can be eliminated from the audio signal path.

Abstract: Techniques are disclosed for monitoring a patient for the occurrence of cardiac arrhythmias. A computing system obtains a cardiac electrogram (EGM) strip for a current patient. Additionally, the computing system may apply a first cardiac rhythm classifier (CRC) with a segment of the cardiac EGM strip as input. The first CRC is trained on training cardiac EGM strips from a first population. The first CRC generates first data regarding an aspect of a cardiac rhythm of the current patient. The computing system may also apply a second CRC with the segment of the cardiac EGM strip as input. The second CRC is trained on training cardiac EGM strips from a smaller, second population. The second CRC generates second data regarding the aspect of the cardiac rhythm of the current patient. The computing system may generate output data based on the first and/or second data.

Abstract: This disclosure provides methods and techniques of performing source network address translation (SNAT) at a packet sender (e.g., a client device) instead of a gateway device (e.g., a proxy device). The present disclosure performs a SNAT operation at the packet sender, relieving the gateway device from the SNAT operation to perform other duties (e.g., policy enforcement). An example method of network address translation includes modifying, by a processing device at a data packet origination device (e.g., a client device), network address information in an internet protocol (IP) header of a packet using a public IP address. The method further includes sending the packet to a public network based on the public IP address.

Abstract: Image fingerprints (embeddings) are generated by an image fingerprinting model and indexed with an approximate nearest neighbors (ANN) model trained to identify the most similar fingerprint based on a subject embedding. For image matching, a score is provided that indicates a similarity between the input embedding and the most similar identified embedding, which allows for matching even when an image has been distorted, rotated, cropped, or otherwise modified. For image classification, the embeddings in the index are clustered and the clusters are labeled. Users can provide just a few images to add to the index as a labeled cluster. The ANN model returns a score and label of the most similar identified embedding for labeling the subject image if the score exceeds a threshold. As improvements are made to the image fingerprinting model, a converter model is trained to convert the original embeddings to be compatible with the new embeddings.

Abstract: Disclosed is a decoupling dipole structure that renders a midband dipole effectively transparent to a nearby lowband dipole. This not only improves the beam quality in the lowband without sacrificing beam quality in the midband, it also enables different lowband dipoles to be employed to customize the lowband performance of the multiband antenna without requiring a redesign of the midband dipoles or of the array face.

Abstract: Disclosed is a radiator assembly configured to operate in the range of 3.4-4.2 GHz. The radiator assembly comprises a folded dipole with four dipole arms that radiate in two orthogonal polarization planes, whereby the signal of each polarization orientation is radiated by two opposite radiator arms that radiate the signal 180 degrees out of phase from each other. The radiator assembly has a balun structure that includes a balun trace that conductively couples to a ground element on the same side of the balun stem plate. The combination of the shape of the folded dipole and the balun structure reduces cross polarization between the two polarization states and maintains strong phase control between the opposing radiator arms.

Abstract: In an approach to intelligent connection placement across multiple logical ports, a mapping table for a virtual machine is created. Responsive to determining that an entry exists in the mapping table for the port on the peer device, whether a virtual function exists the port on the peer device in the mapping table for the same physical function is determined. A virtual function is selected from the mapping table to connect the local port to the port on the peer device.

Abstract: Systems and methods implement measuring, in a test and measurement instrument, operational signal timing parameters of electrical signals being communicated over an electrical bus by a device under test. A bus timing characteristics analyzer identifies nominal signal timing parameters for the acquired electrical signals. The nominal signal timing parameters are defined by the bus protocol and defining timing criteria for the electrical signals. The analyzer measures operational signal timing parameters for each of the acquired electrical signals and compares, for each of the electrical signals, the operational signal timing parameters to the nominal signal timing parameters to determine whether the operational signal timing parameters satisfy the timing criteria. The analyzer then displays, on the test and measurement instrument, a visual indication for each of the electrical signals indicating whether the operational signal timing parameters for the electrical signal satisfy the timing criteria.
