  • Publication number: 20240028281
    Abstract: A display system includes an acquirer, an estimator, and a controller. The acquirer acquires a first detection value and a second detection value from a temperature sensor and a humidity sensor, respectively. The temperature sensor and the humidity sensor are both included in a ventilator that ventilates a room. The estimator estimates, based on the first detection value and the second detection value that are acquired by the acquirer, an apparent temperature distribution representing a distribution of apparent temperatures in a height direction in the room. The controller makes a display device present the apparent temperature distribution estimated by the estimator.

  • Publication number: 20240012057
    Abstract: Methods and controllers manage battery capacities of two or more portable power station (PPS) units connected together in a parallel arrangement to produce a total output current, wherein a first PPS unit operates as a voltage source and each of a second or more PPS unit operates as a current source. Each PPS unit communicates with a battery capacity controller (BCC) wherein each PPS transmits a battery capacity measure to the BCC at selected time intervals. The BCC uses the battery capacity measures to implement a battery capacity control strategy that determines the amount of output current each of the second or more PPS units contributes to the total output current at each time interval. The BCC transmits a control coefficient to each of the second or more PPS units corresponding to the determined amount of output current to be produced by each of the second or more PPS units.

  • Patent number: 11860689
    Abstract: In a time synchronization method, after clock board times between service boards are synchronized, a service board obtains a CPU time and the clock board time of the service board according to a preset periodicity, and makes a record. When performing CPU time synchronization between the service boards, the service board obtains a current CPU time of the service board, calculates a synchronization time of the CPU based on the current CPU time, a last recorded CPU time and clock board time, and adjusts the CPU time of the service board to the synchronization time. After the clock board times between the service boards that need to implement CPU high-precision time synchronization are synchronized by using a high-precision time synchronization protocol, the CPU time of each service board is adjusted to a corresponding synchronization time.
