  • Publication number: 20210364174
    Abstract: The present disclosure discloses a fabricated air conditioner wall and an operation method thereof, and the fabricated air conditioner wall included a precast wall and a heat pump system embedded in the precast wall. The components of the fabricated air conditioner wall are mass-produced and assembled in factories. The fabricated air conditioner wall mainly includes an indoor heat exchanger, a throttle valve, a condensate water tank, a four-way valve, a wall-buried pipe, a compressor, and an outdoor heat exchanger. In a cooling mode, condensate water is collected in the condensate water tank to cool the refrigerant. In winter, when the precast wall is illuminated by sunlight, a temperature of an outer wall is often higher than a temperature of outdoor air, and this solar energy can be reasonably utilized by the wall-buried pipe, thereby improving the heating effect of the air conditioner itself.

  • Patent number: 11176458
    Abstract: Concepts and technologies disclosed herein are directed to the optimization of over-the-air (“OTA”) file distribution for connected cars based upon a heuristic scheduling algorithm. A schedule provided by the heuristic scheduling algorithm is designed to distribute OTA data flow to connected cars over the network (geographically) and over a scheduling time horizon (timely), and is capable of reducing the negative impact of OTA file updates on overall wireless network performance. This schedule is created based upon historical statistics associated with connected car driving patterns and simulations of connected car-specific OTA traffic over the network. By leveraging connected cars that connect to different cells at different times based upon driving patterns, the heuristic scheduling algorithm is effective in reducing OTA impact on the network.

  • Patent number: 10819585
    Abstract: A network device that determines RACH root sequences for AP devices within a given market. The network device can utilize a specialized graph coloring process or algorithm that has been adapted to, e.g., ensure that no two neighboring AP devices share the same RACH root sequences, provided certain additional constraints not found in graph coloring theory are met. For example, AP devices can have multiple RACH root sequence, whereas in traditional graph coloring problems, each vertex typically has only one color.
