Publication number: 20220126326Abstract: Read events capturing parcel information as a parcel is transported through a facility is received, and a configuration file mapping readers capturing the read events to workspace locations within the facility is accessed. Utilizing the read events and configuration file, one or more locations are determined for a parcel being transported through a facility. The locations may form a most likely path, or sequence of locations, through the facility. The determined locations may be utilized for generating one or more graphical user interface elements for tracking parcel and/or other operational aspects. For example, a graphical user interface may indicate errors, such as errors in the parcel's path and slowdowns, detected from the read events. Additionally, volume of parcels over time may be determined from the read events. Further, a graphical user interface may indicate employee performance based on errors and/or read events attributed to the employee.Type: ApplicationFiled: October 23, 2020Publication date: April 28, 2022Inventors: Mallory Freeman, Timothy Major, David Wu, Lauren Skorb, Matthew Britton

Publication number: 20220110495Abstract: A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening.

Patent number: 11278171Abstract: A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) 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 rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.Type: GrantFiled: October 21, 2016Date of Patent: March 22, 2022Assignee: SharkNinja Operating LLCInventors: Steven Paul Carter, Adam Udy, Catriona A.
