Embodiments of the present invention provide methods, computer program products, and systems for selecting subsets of participants in electronic message threads. Embodiments of the present invention can be used to exclude participants based, at least in part, on activity level from message conversations, thereby streamlining message conversation and reducing unwanted message communications.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

The present invention relates to attaching aerodynamic wheel covers to the wheel of a truck or other heavy duty vehicle, and to a method of installation that requires less tooling for installation while substantially completely covering the wheel.

A wheel cover assembly for a wheel of a motor vehicle may include a wheel body and a cover portion arranged on an outside of the wheel body. The cover portion may be guided on the wheel body so as to be movable relative to the wheel body between an open position allowing an air flow between the outside and an inside of the wheel body, and a closed position preventing the air flow. Conversion from the open position to the closed position takes place automatically based on an operating state of the wheel. The cover portion may be configured as a disc-like component covering the outside. The cover portion may be arranged movably parallel to an axis of the wheel body between the open position and the closed position, in the open position opening a ring gap between an edge of the cover portion and the wheel body.

A vehicle wheel structure includes: a wheel configured to support a tire and be assembled to a vehicle; a wheel cover engaged with the wheel at least at a central part of a disc that is a component of the wheel, the wheel cover in a state attached to the wheel including a body formed so as to cover an entire surface, corresponding to an outer side of the vehicle, of the disc when the wheel is assembled to the vehicle and an engaging portion provided on the body and configured to engage with an engaged portion provided at the central part of the disc; and a restricting member configured to restrict movement of the engaging portion in a releasing direction to release engagement with the engaged portion in a state where the engaging portion is engaged with the engaged portion.

A method of manufacturing a cast vehicle wheel including a wheel trim cover attached thereto. A removable first tool insert is installed into a mold assembly. The tool insert includes a mounting feature that communicates with a cavity of the mold assembly to form a mating feature in the wheel. A wheel trim cover is provided and is attached to the wheel at the mating feature via a coupler formed in the wheel trim cover such that the relative position of the coupler and the mating feature positions the wheel trim cover relative to the wheel in a first predetermined position. After casting, the positional dimensions of the mating feature of the wheel relative to the coupler of the wheel trim cover is evaluated to determine the positional accuracy of the mounting feature of the first tool insert. If necessary, secondary inserts with improved mating features are provided and exchanged.
