Abstract: The present disclosure provides a display panel and a liquid crystal display device. The display panel includes an array substrate and a flexible thin film. The array substrate has a first surface, a second surface disposed opposite to and in parallel with the first surface, and a first side surface connected to the first surface and the second surface. The first surface of the array substrate is on a same side as a light-emitting surface of the array substrate, and the flexible thin film is disposed on a side of the second surface of the array substrate. The display panel and the liquid crystal display device have narrow frames.

Abstract: A wireless tracking system comprises mobile devices and stationary devices at known locations. The system receives a first radio measurement indicative of a first propagation path length and receives sensor data indicative of the movement of the first mobile device. The sensor data is of a type different to the radio measurement. The system then determines a historical location of the first mobile device based on the first radio measurement and the sensor data and determines error data indicative of a difference between a historical radio measurement and the historical location and stores the error data associated with the historical location. The system can then receive a second radio measurement indicative of a second propagation path length of radio frequency radiation and determine an estimated location of the second mobile device based on the second radio measurement and the stored error data.

Abstract: Signal interference associated with multi-user multiple-input multiple-output (MIMO) full-duplex wireless communication systems is reduced. In an example, first streams are received by a MIMO base station from uplink user devices based on a first availability of channel matrices and second streams are transmitted to downlink user devices based on a second availability of the channel matrices. A weighted sum of a first data rate for a first linear transceiver matrix and a second data rate of a second linear transceiver matrix is maximized based on the channel matrices, the first streams, and the second streams. The base station generates a first linear transceiver vector used in transmission of the first streams to the base station from the uplink user devices and a second linear transceiver vector used in transmission of the second streams from the base station to the downlink user devices.
