  • Fan assembly
    Patent number: 9745981
    Abstract: A nozzle for a fan assembly has an air inlet, an annular air outlet, and an interior passage for conveying air from the air inlet to the air outlet. The interior passage is located between an annular inner wall, and an outer wall extending about the inner wall. The inner wall at least partially defines a bore through which air from outside the nozzle is drawn by air emitted from the air outlet. The inner wall is eccentric with respect to the outer wall so that the cross-sectional area of the interior passage varies about the bore. The variation in the cross-sectional area of the interior passage can control the direction in which air is emitted from around the air outlet to reduce turbulence in the air flow generated by the fan assembly.

  • Discovery of Wi-Fi direct services via discovery probe
    Patent number: 9723545
    Abstract: Methods, systems, and devices are described for Wi-Fi peer-to-peer (P2P) communications. A seeker user equipment (UE) may identify a desired service to be provided via Wi-Fi P2P communication. The seeker UE may broadcast a probe that identifies the desired service. An advertiser UE may receive the probe from the seeker UE. The probe identifies a desired service for the seeker UE that is to be provided via Wi-Fi P2P communication. The advertiser UE may transmit a probe response to the seeker UE only when it is determined that the advertiser UE is capable of providing the identified desired service.

  • Vacuum cleaner tool
    Patent number: 9700188
    Abstract: A tool for a vacuum cleaner that comprises a nozzle and a bristle assembly. A suction opening is provided in the base of the nozzle, which extends from a front to a rear of the nozzle. The bristle assembly is mounted within the nozzle and protrudes through the suction opening. The suction opening is delimited along its length by a leading edge and a trailing edge, and at least part of the leading edge is raised relative to a front end and a rear end of the nozzle.
