  • Patent number: 11695234
    Abstract: A pluggable module includes a housing and cables arranged as a cable bundle extending from a module cavity of the housing. Each cable includes first and second conductors and an insulator surrounding the conductors. Each cable is obround shaped having generally flat first and second ends and semi-circular first and second sides between the first and second ends. The pluggable module includes a cable organizer coupled to the cable bundle to position the cables relative to each other.

  • Patent number: 11580584
    Abstract: A network-based service may be provided for facilitating queries for a number of items, such as travel services. A user may submit a query including criteria for determining one or more relevant items. Based on the submitted query, the network-based service may present the user with information regarding the actions of other similar users of the network-based service, such as searches performed by the other users. Based on this information, the user may elect to supplement the current query to conform to the actions for other users. In some embodiments, actions by other users may be based at least in part on a category of the querying user. By presenting actions of similar users, a current user may be enabled to select the most relevant query terms for identifying a desired item.

  • Publication number: 20210012608
    Abstract: A gaming system and a related method provide a game that includes symbol display areas and one or more cluster patterns that can be associated with two or more of the symbol display areas to create a winning outcome and one or more awards. The gaming system includes one or more symbol sets that provide symbols displayed in the symbol display areas, and a cluster pattern may be associated with a grouping of one or more of the symbol display areas. Cluster patterns of different sizes and shapes, or multiple similar shaped and sized cluster patterns positioned in different locations may be used. The gaming system evaluates symbols displayed in a grouping of the symbol display areas associated with a cluster pattern to determine an award. The gaming system may further evaluate the symbol display areas to determine other awards associated with the displayed symbols.
