  • Publication number: 20240430007
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity via an optical wireless communication link, a first optical wireless signal using photodetectors positioned on a photodetector panel of the UE. The photodetector panel may include a hole around which the photodetectors are positioned and may be located a first distance from a curved optical device of the UE via which the first optical wireless signal is received. The UE may transmit, to the network entity via the optical wireless communication link, a second optical wireless signal using a light source of the UE that is located a second distance from the curved optical device via which the second optical wireless signal is transmitted. The second optical wireless signal may pass through the hole in the photodetector panel based on the second distance being greater than the first distance.

  • Publication number: 20240405867
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in an optical wireless communications system may utilize a curved focal plane of a condenser lens to communicate an optical wireless signal. An optical front-end (OFE) of the UE may include one or more optical communication components located at varying distances from the condenser lens on a curved focal plane of the condenser lens. Additionally or alternatively, the UE may adjust a position of one or more optical communication components on the curved focal plane. Additionally or alternatively, the OFE may include an array of condenser lenses and optical communication components each optically coupled with one or more condenser lenses. The UE may perform equal gain combination and/or equal ratio power splitting to communicate an optical wireless signal using the array of condenser lenses and optical communication components.

  • Publication number: 20240292992
    Abstract: A docking station for a vacuum cleaner may include a receptacle configured to engage at least a portion of the vacuum cleaner such that, in response to engaging the receptacle, a vacuum cleaner flow path extending within the vacuum cleaner is transitioned from a cleaning flow path to an evacuation flow path, a suction motor of the vacuum cleaner being configured to urge air along the vacuum cleaner flow path and a docking station dust cup configured to receive debris from a vacuum cleaner dust cup of the vacuum cleaner.

  • Publication number: 20240145991
    Abstract: An outlet module mounting mechanism for use with a power distribution unit including: a bracket attachable to an outlet module; a latch movably coupled to the bracket, wherein the latch has a proximal end portion and a distal end portion; a link coupled to the proximal end portion of the latch; and a plunger connected to the link and movable between a released position and a latched position. When the plunger is moved to the latched position the plunger moves the link away from a front side of the outlet module such that the distal end portion of the at least one latch moves toward the front side of the outlet module to engage a corresponding wall of the housing thereby securing the outlet module to the housing.

  • Publication number: 20240057839
    Abstract: A flexible flap coupled to the bottom of a cleaning tool is designed to have a distal end that contacts the floor and scrapes along the floor as the cleaning tool is moved across the floor in order to help guide debris into a catch tray. The flexible flap also has a design such that the distal end can curl inwards after interaction with an obstacle (e.g., recess or protrusion of the floor surface) and continue to move across the floor picking up debris, even after the distal end of the flexible flap has been curled.

  • Publication number: 20240008701
    Abstract: A door opening mechanism is operable by an actuator (1140) to open a dirt chamber door (1070) to a dirt collection chamber (1066). The door (1070) is movable about a pivot (1072) between a closed position and an open position. In some examples, the actuator (1140) may be located on the same side of the dirt collection chamber (1066) as the pivot (1072). In some examples, the actuator (1140) may be positioned vertically higher than the pivot (1072) when the dirt collection chamber (1066) is in the emptied position.

  • Patent number: 11864719
    Abstract: An example of a system, consistent with the present disclosure, may include a motor-battery assembly. The motor-battery assembly may include a housing defining one or more cavities, a suction motor configured to be fluidly coupled to a debris compartment of a vacuum cleaner for generating air flow through the vacuum cleaner for entraining debris, one or more batteries at least partially disposed within at least one of the one or more cavities, and a motor/battery controller at least partially disposed within at least one of the one or more cavities, the motor/battery controller configured to control power provided to the suction motor and to regulate charging and/or discharging of the one or more batteries.

  • Patent number: 11712139
    Abstract: A surface cleaning head with a leading roller may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The surface cleaning head may have dual agitators—a leading roller and a rotating brush roll—with the leading roller being located in front of the brush roll. The leading roller may have a smaller diameter than the brush roll and may provide a softer cleaning element. The leading roller may also have a bottom portion exposed to the flow path to the suction conduit and at least a top half that is not exposed to that flow path. The leading roller may also float relative to the surface cleaning head and/or may be adjustable relative to the brush roll.
