Abstract: This document describes systems and techniques directed at concurrent communication in multiple time-division duplex (TDD) bands. As new industry standards (e.g., the Fifth Generation New Radio (5G NR) standard) are being implemented, more TDD bands are becoming available for wireless communications. Generally, manufacturers will add additional antenna systems for each TDD band, but this method may become costly and need extra space, which is already limited, within the user device In various aspects, the concurrent communication system includes a radio frequency (RF) modem module configured to operate on multiple TDD bands, which may include bands that are located near each other on the RF spectrum. The concurrent communication system further includes transceiver circuitry with at least one transmission chain and at least four reception chains. The architecture of this system offers an efficient and inexpensive way to communicate on at least two TDD bands concurrently with reduced hardware cost.

Abstract: Systems and methods are described for testing server configuration across a secured network edge. A server administrator submitting configuration instructions from an external network separated from an internal network by a network boundary device may not have adequate access for proper testing. A test platform within the internal network receives, from a management device in the external network, a test request indicating a client characteristic. The test platform generates a data request with origination information for a source of the data request conforming to the indicated client characteristic and transmits the generated data request to a data server within the internal network responsive to receiving the test request from the management device. The test platform then receives a response to the generated data request and provides, to the management device in the external network, a report based on the received response.

The system can analyze the frames to identify a subset of consecutive frames that have a static portion defined by a spatial region with matching pixels across two or more frames. The system can tag the digital video with an indication of the subset and a trigger that causes transmission, at a temporal offset during playback prior to the subset, of a request for content used to overwrite the static portion. The system can receive the request from the client device, the request transmitted by the client device based on the temporal offset during playback prior to the subset. The system can select and transmit a content item responsive to the request to cause the client device to render the content item at the static portion of the subset.

Abstract: A test system for detecting impairment aboard a motor vehicle includes an electronic control unit (ECU) and sensors in communication therewith. The sensors are positioned within a vehicle interior, and include at least a touch screen and a microphone, and possibly an eye-tracking camera. In response to receiving a start request indicative of a requested start event of the motor vehicle, the ECU executes instructions to initiate a cognitive response test via the sensors. The ECU determines a test score of a driver during the test while the motor vehicle remains off, compares the test score to baseline scores to determine a passing or failing test result, and executes a control action aboard the motor vehicle in response to the passing or failing test result. The ECU may disable or immobilize the motor vehicle in response to the failing test result.
