  • Adaptive compensation of wear in person lifting assemblies
    Patent number: 11007101
    Abstract: A motive system for a patient lifting assembly, a patient lifting assembly and a method of operating a patient lifting assembly. The motive system includes an electric motor, numerous sensors and an adaptive control unit cooperative with one another so that a memory and processor that are part of the control unit that can respectively store and execute a computer readable and executable instruction set. By comparing collected data from the sensors during operation of the motor to corresponding reference values associated with one or more motor operational parameters—such as accumulated motor wear over time or differences in operating temperature of the motor—the system can selectively adjust the maximum amount of current available for use by the motor. In this way, changes in motor efficiencies that arise with these parametric changes can be taken into consideration when determining an upper limit on how much electrical current may be delivered to the motor for a given load.

  • SOFT DECODING OF RATE-COMPATIBLE POLAR CODES
    Publication number: 20210119648
    Abstract: A node receives transmissions associated with a given set of information bits, wherein each of the transmissions use a different polar code and share one or more information bits of the given set of information bits. The node determines, at each of a plurality of polar decoders of the node, soft information for each information bit included in an associated one of the transmissions, wherein each of the plurality of polar decoders is associated with a different transmission of the transmissions. The node provides, from each polar decoder of the plurality to one or more other polar decoders of the plurality, the determined soft information for any information bits shared by their respective associated transmissions, and uses the provided soft information in an iterative decoding process to decode one or more of the received transmissions.

  • CQI CODEPOINT REINTERPRETATION
    Publication number: 20200382261
    Abstract: According to an aspect, a wireless device is configured to report, to a base station, channel quality information (CQI) using a predetermined set of CQI index values, where each CQI index value is interpreted by the wireless device and the base station as corresponding to a combination of modulation and coding rate. The wireless device determines, based on a downlink signal configuration, that a first one of the CQI index values corresponds to no modulation and coding rate that can be used for transmissions to the wireless device from the base station. The wireless device transmits the first CQI index value to the base station to signal information other than a combination of modulation and coding rate. The base station receives the first CQI index value and interprets it to signal information other than a combination of modulating and coding rate.
