Abstract: A safety sensing system implements a method for a person in an industrial environment comprises providing a personnel locator device (10) for location on a person and a reference system comprising a plurality of nodes (20) located at predetermined ocations in the industrial environment (100). Radio ranging signals are transmitted between the nodes (20) and the personnel locator device (10) and measurements of times of flight of the radio ranging signals are derived. The location of the personnel locator device (10) is calculated based on the measurements of the times of flight of the radio ranging signals and reference information representing the predetermined locations of the nodes (10). It is determined if the calculated location of the personnel locator device (10) is within ne or more danger zones in the industrial environment (100) and a warning signal is output in response thereto.

Abstract: An animal tether system and method wherein the rate of extension and retraction of the tether and/or the length of the tether can be actively controlled at least in part as a function of the angular direction and/or speed and/or length of which the tether extends/retracts. The system can be used to maintain an animal in a non-circular boundary, such as a rectangular space, by controlling how far the tether can extend at certain angular positions. The system also allows a user to block off certain areas within a space from access by the animal.

Abstract: Methods, systems, and devices for wireless communication are described. In multi-user (MU) multiple-input multiple-output (MIMO) wireless communications systems, a base station may perform signaling to indicate information related to ports assigned to one or more UEs.

In some examples, the base station may signal a number of ports used per sub-band to the UE or a number of demodulation reference signal (DMRS) ports used by the UE. The base station may signal a sub-set of a total number of ports that are shared by other UEs overlapping with the resource allocation of the UE. The signaling may indicate a number of combs used by the base station in the resource allocation for the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Communications by wireless devices may be modified when beam pair links (BPLs) experience decreased link quality. For example, a controlling wireless device may communicate with a secondary wireless device using a set of BPLs. The controlling and secondary wireless device may each cycle through the set of BPLs at respective times of a communication time period. Upon detecting one or more BPLs having a decreased link quality during a portion of the communication time period, the controlling wireless device may transmit a configuration modifying the communications. For instance, the modified communications may include replacing the one or more BPLs with different BPLs having a relatively higher link quality. In other cases, the modified communications may include using repeated transmissions during the portion of the communication time period or excluding the BPLs experiencing decreased link quality from the communication time period.

Abstract: Certain aspects of the present disclosure provide techniques for precoding for multi-panel uplink transmission. For codebook-based uplink transmission, a user equipment (UE) can determine one or more preferred or selected precoders for uplink transmission. The precoders can be from an expanded UE codebook that maps a first number of transmit layers at the UE to a second number of antenna ports at the UE, the layers and/or antenna ports associated with multiple uplink transmit panels at the UE. The UE sends an indication to a base station (BS) of the determined precoders and/or sends an uplink transmission using the determined precoders. For non-codebook based uplink transmission the UE receives first and second reference signals (RSs), from first and second ports of a BS, with first and second UE antenna panels. The UE computes precoders to use for uplink transmission based on the RSs.
