Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage media for Uplink Control Information (UCI) design. The method comprises determining, at a terminal device, a matrix comprising a set of non-zero linear combination coefficients for quantizing a channel between the terminal device and a network device, the matrix having spatial components and frequency components; shifting the frequency components of the matrix circularly, such that a target coefficient of the set of non-zero linear combination coefficients is located in a frequency component with a predetermined index of the frequency components in a shifted matrix; generating a first indication indicating the spatial component associated with the target coefficient in the matrix; and transmitting, to the network device, uplink control information comprising the first indication. In this way, a new solution for designing the UCI may reduce the overhead for reporting the parameters in the UCI.

Abstract: The present invention offers some general specifications for the design, assembly, and adaptation of a rotating cylinder electrochemical cell into an autoclave, of a high temperature and pressure system for corrosion studies that simulate operating conditions in pipelines, as well as the operation and safety of an autoclave to evaluate the electrochemical process of metal surfaces exposed to aggressive aqueous solutions. The electrochemical cell consists of an array of three electrodes that include a rotating cylinder electrode designed to operate hermetically, a reference electrode and an auxiliary electrode. The rotating cylinder electrode is considered to be the working electrode, where the oxidation and electrochemical reduction processes are studied. However, the use of the method described in this work can be extended to other testing environments and materials by taking into account the physical and chemical properties of the fluids and materials to be used in order to avoid any risk for the operator.

Abstract: The present disclosure provides a battery pack including a housing, wherein the housing has a bottom portion and side walls extending upward around a periphery of the bottom portion; an upper portion opening is formed at top ends of the side walls extending upward; an upper cover is mounted on the upper portion opening of the housing; and the battery pack comprises: multiple flat battery cells; and a first end plate and a second end plate, wherein when the multiple battery cells are sequentially arranged and mounted into the housing from the upper portion opening, the first end plate and the second end plate are located at two end sides of the sequentially arranged multiple battery cells to laterally fix the sequentially arranged multiple battery cells. The two end plates may absorb deformation of the battery cell while expanding.

Abstract: Aspects described herein include devices and methods for phase tracking and correction using sampling. One aspect includes a wireless communication apparatus having an analog 1-bit sampler configured to sample a phase locked loop (PLL) output signal using a PLL reference clock to generate 1-bit samples and a digital phase computation and control circuit configured to receive the 1-bit samples from the analog 1-bit sampler and apply phase corrections to the PLL based on a phase error derived from the 1-bit samples.

Abstract: A device for charging various batteries in multiple deployable units, such as small unmanned aircraft systems and their ancillary devices. The device provides an efficient means of charging multiple unmanned aerial vehicle batteries using a high output power, while simultaneously charging multiple Ground Control Station batteries and an external device, such as a laptop or tablet. The device provides a precise readout in real time of each cell's charge, the battery's overall charge, and the percentage of charge.
