  • Patent number: 11981208
    Abstract: A control system for a vehicle comprises a controller comprising a processor and a non-transitory computer-readable medium including instructions. The system comprises a transformable knob manipulated between first and second states. The knob comprises a body having a periphery wall arranged to flex between first and second configurations with the first and second states, respectively. The system comprises an output device arranged to change between first and second settings. Manipulation of the transformable knob from the first state to the second state transmits an input signal to the controller and facilitates flexing of the periphery wall from the first configuration to the second configuration. The controller receives the input signal, and the processor compares the input signal to the instructions in the non-transitory computer-readable medium and transmit an output signal to the output device to change the output device from the first setting to the second setting.

  • Patent number: 11924773
    Abstract: The present invention relates to an apparatus and method for controlling uplink transmission power in a multiple element carrier wave system. The method for controlling uplink transmission power by a terminal in a multiple element carrier wave system includes the steps of: generating an uplink signal to be transmitted in a first serving cell; receiving, from a base station, random access start information for commanding the start of a random access procedure for a second serving cell; calculating the estimated surplus power from first transmission power scheduled for an uplink signal transmission, and second transmission power scheduled for a transmission of a PRACH to which a random access preamble is mapped; and when the estimated surplus power is smaller than a threshold power, adjusting the first transmission power or the second transmission power on the basis of power allocation priority.

  • Patent number: 11440483
    Abstract: A system and method that pertain to a rotating vehicle display unit that can automatically or manually rotate between landscape and portrait orientations, depending on the particular display format or media being shown to the vehicle occupants. The rotating vehicle display unit uses an electro-mechanical rotating and locking mechanism with smart fluid, such as magnetorheological fluid (MR), to facilitate easy and precise rotational movement between different display orientations. The rotating vehicle display unit may be coupled to a corresponding human-machine interface (HMI) that responds to the different display orientations and helps facilitate easy transition from one orientation to another in order to optimize the particular display format or media being shown at that time.
