Abstract: A method may include determining a combination of values of attributes represented by reference data associated with payment transaction by training a machine learning model based on an association between (i) respective values of the attributes and (ii) the payment transactions having a given result. The combination may be correlated with having the given result. The method may also include selecting a subset of the payment transactions that is associated with the combination of values. The method may additionally include determining a first rate at which payment transactions of the subset have the given result during a first time period and a second rate at which one or more payment transactions associated with the combination have the given result during a second time period, and generating an indication that the two rates differ.

Abstract: One example method includes receiving, by a video conference provider, a request to initiate an emergency beacon and determining, by the video conference provider, a first client device associated with the request. The method may also include activating, by the video conference provider, the emergency beacon for the first client device and establishing, by the video conference provider, a virtual session based on the emergency beacon. The method may also include joining, by the video conference provider, the first client device to the virtual session without input from the first client device and transmitting, by the video conference provider, a request to join an authorized device to the virtual session.

Abstract: A system can automatically search and gather participant information in connection with an event. The search for participant information for a participant is triggered when a positive action for the event is received from the participant. The participant information is gathered from at least one of public, private and software platform resources. The gathered participant information is processed to resolve consistency issues due to the different sources. The resolved participant information is formatted and transmitted to the client devices for display and stored in private resources associated with the participant.

Abstract: An example method of ultra-wideband (UWB) sensing performed by a wireless communication device, the method comprising determining a first channel impulse response (CIR) estimation of a first frequency channel based on a radio access technology (RAT) session, wherein the RAT is different from UWB. The method also comprises determining a second CIR estimation of a second frequency channel based on a UWB session and determining a third CIR estimation of the first frequency channel based on determining a phase difference between the third CIR estimation and the first CIR estimation. The method further comprises determining a total CIR estimation for a combined frequency channel comprising the first frequency channel and the second frequency channel based on stitching the first CIR estimation, the second CIR estimation, and the third CIR estimation.

Abstract: Methods and systems provide for dynamically presenting at least one attentional element within a communication session. The system presents, to each of a number of participants within a communication session, a user interface (“UI”) for the communication session. The system receives a signal of an event associated with a first participant intending to communicate with a second participant, with the second participant not acknowledging the intended communication. The system determines, after a predefined period of time, that the intended communication from the first user has not been acknowledged by the second user and that the event has not yet terminated. The system then initiates an attentional element within the UI of the second participant, the attentional element being more pronounced than the notification.

Abstract: In some implementations, a server may send a request to a first wireless device for capability information, wherein the first wireless device is capable of transmitting both cellular and ultra-wideband (UWB) wireless signals. The server may receive a response from the first wireless device, the response comprising the capability information regarding a capability of the first wireless device for performing UWB positioning. The server may determine first UWB assistance data for the first wireless device based at least in part on (i) the capability information and (ii) information regarding one or more positioning signals transmitted in a cellular wireless network, wherein the first UWB assistance data comprises one or more parameters for a first set of one or more UWB positioning sessions between the first wireless device and a second wireless device. The server may send the first UWB assistance data from the server to the first wireless device.

Abstract: The relative position of a user equipment (UE) within a vehicle is determined using angular measurements, such as angle of arrival (AOA), and optionally ranging measurements, with respect to a number of wireless transceivers within the vehicle using wideband signals. The relative position of the UE with respect to a personal zone or the steering wheel may be determined based on known positions of the wireless transceivers. If the UE is determined to be within the personal zone, at least one functionality of the UE is restricted to avoid driver distraction and, optionally, the operation autonomous driving of the vehicle adjusted. If the UE is worn on the driver's wrist the relative position of the UE with respect to the steering wheel may be similarly determined and operation of the vehicle modified if the UE is determined to be outside a threshold distance from the steering wheel.

Abstract: This disclosure provides methods, components, devices and systems for adjacent channel interference (ACI) mitigation techniques for ultra-wideband (UWB) systems. Some aspects more specifically relate to ACI mitigation for UWB systems. In some implementations, a wireless communication device may receive control information that identifies a preamble for communications to the wireless communication device in a UWB system.

The wireless communication device may estimate a channel impulse response (CIR) of the signal and determine an interference metric that is based on the estimated CIR. The wireless communication device may process the data packet based on the interference metric.

Abstract: A text communication is received from a telephone number of a sender. The text communication is directed to a recipient. A determination is made as to whether to challenge the sender. Responsive to determining to challenge the sender, a challenge is transmitted to the sender. A determination is made as to whether to route the text communication to the recipient based on whether a successful response to the challenge is received from the sender.
