Abstract: Techniques are described for using a dedicated-scan radio to improve scanning and other radio operations performed during wireless communications. The techniques include configuring a dedicated-scan radio to collect and cache scan results without interfering with ongoing wireless communication tasks performed using primary radios. Based on the scan results cached by the dedicated-scan radio, the computing device improves other radio operations in furtherance of wireless communications. Cached scan results enable a primary radio to avoid, or to focus on, scanning certain channels or frequencies during discovering, positioning, or roaming operations. By using the dedicated-scan results as a starting point or seed for functions performed by a primary radio, the computing device may more quickly and more efficiently perform radio functions, minimizing latency to ongoing wireless communications.

Abstract: A method that includes receiving a first configuration and a second configuration that define a set of rules for matching and merging a set of source data objects that are associated with a tenant and that are received from a plurality of data sources. The method may further include generating a set of merged data objects from the set of source data objects based on an identification of matching values from fields of the set of source data objects and selecting a value for each field of each merged data object having multiple values. The method may further include generating a mapping between primary keys associated with each merged data object and corresponding primary keys of the source data objects. The method may further include storing the merged data objects and the mappings in a first datastore and a second datastore that is different from the first datastore.

Abstract: This document describes methods, devices, systems, and means for a switching scheme for opting in and out of multi-user orthogonal frequency-division multiple access (MU-OFDMA). In one aspect, an electronic device enters the MU-OFDMA mode to communicate via a wireless network over a shared-channel bandwidth. During the MU-OFDMA mode, the electronic device determines that an uplink-queue size is greater than a first threshold size. Responsive to the determining, the electronic device opts out of the MU-OFDMA mode and enters a single-user mode to contend for a transmit channel for transmitting uplink data.

An example system includes an antenna array and a calibration circuitry. The antenna array includes a plurality of antenna cells arranged in K rows and L columns, each cell including a plurality of dual-polarization antenna elements.

Abstract: Techniques are described herein that are capable of offloading upload processing of a file in a distributed system. A request is received from a requestor to upload a file to a transactional database of a DBMS. Information regarding the requestor and/or the file is extracted from the request. A determination is made that the file is to be uploaded to a non-indexing file storage system in lieu of the transactional database based at least in part on the extracted information satisfying one or more criteria. A key that includes a hash is generated. The hash is created using attribute(s) of the requestor and/or the file from the extracted information. The key is provided to the requestor. The key and at least a portion of the file are received from the requestor. Uploading of the file to the non-indexing file storage system in lieu of the transactional database is initiated.

Abstract: Coordination of RRC configurations between an LTE NB and an NR NB in dual connectivity with a UE are performed using an RRC container that includes shared or coordinated parameters. For example, an NR NB determines to alter a configuration of a UE. The NR NB transmits a coordinated RRC container with coordinated UE parameters to an LTE NB and transmits a UE parameter RRC container to the LTE NB. The LTE NB evaluates the coordinated container for compliance with the UE capability. If satisfied, the LTE NB can send both containers (in a single RRC message or multiple RRC messages) to the UE.

Abstract: The infrared alignment guide for an x-ray machine is used to align a target tooth and an x-ray sensor with transmitted x-rays, as well as aligning the transmitted x-rays with a most effective orientation for imaging the target tooth. The guide includes a body having an attached x-ray sensor holder. The x-ray sensor holder may be adjusted in relation to the body for imaging different teeth. The x-ray sensor holder emits infrared light towards the body, which is detected by an infrared camera on the front of the body. The image produced by the infrared camera, which shows the crowns of the teeth, is used to align the transmitted x-rays with the tooth and the x-ray sensor holder.

Abstract: A mechanism for customer service with security and privacy is provided. In a support service scenario for products or services, a determination is made based on an interaction with a customer that additional verification is needed. An authentication code is communicated to the customer via a mode chosen by the customer. At the same time, a hash of the authentication code is stored along with session and customer details. The customer is prompted to provide the authentication code and a hash of the provided authentication code is compared to the hash of the authentication code that was stored with the session and customer details. If the hashes match, it can be presumed that the agent is communicating with the correct customer and customer details are revealed. If the hashes do not match, the agent does not see any private customer details.
