  • Publication number: 20170096108
    Abstract: A sliding storage compartment assembly for a motor vehicle includes a storage bin slidably received in a storage bin holder by a dual track assembly defined by opposed sets of rails and opposed sets of cooperating tracks. Each of the opposed sets of rails and opposed sets of cooperating tracks are vertically and laterally offset one from another. Each of the opposed sets of rails and each of the opposed sets of cooperating tracks may be vertically offset one from another in a vehicle z-axis direction and laterally offset from one another in a vehicle x-axis direction. The opposed sets of cooperating tracks may be disposed on opposed side walls of the storage bin holder and the opposed sets of rails may be disposed on opposed side walls of the storage bin, or vice-versa. Console assemblies including the sliding storage compartment assembly are described.

  • Publication number: 20170021893
    Abstract: A transportation device includes a frame foldable between a bicycle configuration and a personal transporter configuration. A sensor configured to sense when the frame is in at least one of the bicycle configuration and the personal transporter configuration. A first wheel and a second wheel are each rotatably coupled to the frame. A first motor is coupled to the first wheel and a second motor is coupled to the second wheel. A controller is programmed to instruct the first motor to rotate in a first direction in response to a signal from the sensor that the frame is in the bicycle configuration, and to instruct the first motor to rotate in a second direction opposite the first direction in response to a signal from the sensor that the frame is in the personal transporter configuration.

  • Patent number: 8870486
    Abstract: Exchangeable attachments and apparatus and methods for retaining exchangeable and tradable attachments, such as attachments that are removably attached to a retainer. Retainers may be located on, for example, the non-marking end of a writing implement, hair barrettes, shoe laces, bracelets, broaches, earrings, keychains, necklaces, rings, etc. Attachments may be coupled to a receptacle located in the retainer, wherein the attachment is inserted into a receptacle and rotated in a first direction to couple the attachment to the retainer, and wherein the attachment is rotated in a second direction and removed from the receptacle to uncouple the attachment from the retainer. Attachments may be stored internal to the apparatus to which the retainer is attached. Attachments may include identifying indicia or other designs. The retainer may include protrusions or another type of stand to allow the attachments to be displayed while the retainer is removed from the writing implement.

  • Publication number: 20070163165
    Abstract: Surface treatment for fishing lures and sinkers is disclosed. The surface treatment can exist in a number of configurations, including holes, slots, grooves, or other details. The details have a cross section that allow them to be easily cleaned with a stick, branch, sand or other items that can be found near a lake or stream. The surface treatment allows a person to manually apply fish attractant to the outer surface of the fishing lure, and some of the fish attractant will embed into the surface treatment area providing retention of the fish attractant. In use the fish attractant will be washed from the surface treatment as the lure is moved through the water. The surface treatment can be incorporated into nearly any type of rigid or pliable fishing lure or sinker.
