Abstract: The device includes a housing, a printed circuit board, a first optical subassembly, a second optical subassembly, and a lever. The device is pluggable to a host structure. The housing has a flange. The printed circuit board is mounted to the housing. The first and second optical subassemblies are mounted to the printed circuit board. The lever is rotatably mounted to the housing. The lever includes a rotatably mounted portion, a hook, and an actuation surface for actuation by a user. In a plugged into and locked position of the device with the host structure, the flange of the housing is in electrical communication with a faceplate of the host structure, and the hook engages a slot.

Abstract: A system and application for providing a user with interactive and individualized assistance in selecting an appropriate product for the user based on one or more user-selected goals is provided. The consumer or user accesses the application over a computer network such as the Internet and selects items for purchase from a database. The graphical interface can organize the products, for example, by a pre-selected value, a product category, or the consumer's historical shopping data. The application then reviews the selected products or items and recommends substitutions to help the consumer achieve specified goals. The application also includes additional functionality to permit the consumer to shop on a collection of products basis, e.g.
