Patent number: 11106334Abstract: A system and method for displaying a user interface may include an examination and/or elimination of positional bias of interactive categories in order to drive user engagement. A method or system configured to execute the method on a user interface may include creating a first arrangement of categories. The arrangement can be shown on a user device to one or more users a selected number of times. The users' interactions with the categories in the interface may be recorded. The method may further include creating a second arrangement, which is different from the first arrangement, and this second arrangement may be shown to the users the selected number of times and the users' interactions with the second arrangement may be recorded. Based on the frequency of user interactions with the first and second arrangement, a ranked set of the categories may be created and displayed to users.Type: GrantFiled: May 29, 2020Date of Patent: August 31, 2021Assignee: Home Depot Product Authority, LLCInventor: Toshivv C.

Publication number: 20210071043Abstract: The present disclosure relates to adhesive article that include a stretch releasable adhesive and topographical, engineered elements on, within, or partially embedded in a surface of the adhesive. The engineered elements can act as spacers between the adhesive surface and the mounting surface to prevent full contact and wet out of the adhesive, whereby the article can be initially positioned or rotated by sliding the surface of the projections across the wall surface. Under certain conditions, the article may even be removed from the wall and placed at a new location without damage to the wall surface or the article. Once the location is selected, the separation created by the engineered elements can be overcome by applying sufficient pressure; the adhesive can contact and adhere more permanently to the wall.Type: ApplicationFiled: May 8, 2019Publication date: March 11, 2021Inventors: Payam Khodaparast, Nishant C.
