Abstract: A rotary control knob apparatus includes a stationary knob retainer having a cylindrical post and an annular knob that slides over the retainer post, where the exterior periphery of the retainer post has a distributed array of compliant protrusions that contact the inner periphery of the knob to provide a resilient sliding interference fit between the knob and the retainer post. In a preferred arrangement, the retainer is secured against the rear surface of a control panel trimplate, and the knob is axially captured between the trimplate and a retainer flange extending radially outward from the base of the cylindrical post.

Abstract: A player for a media unit. The player includes a front plate formed of metal and having an opening configured to receive a media unit. The player also includes a cover mounted over the opening and having a slit. The slit is aligned with the opening and configured to allow the media unit to pass through the cover and enter the opening. The cover includes an electrical conductor that contacts the front plate and is in electrostatic communication with the slit. The conductor conducts electrostatic charge from the media unit to the front plate as the media unit passes through the slit. The media unit may be a CD, DVD, memory stick, minidisc or the like.

Abstract: A button assembly comprising a panel having a hole and a button configured to extend through the hole. The assembly further includes an integral switch pad and gasket member, with the switch pad having a base and a flexible dome including a contact extending from the base. The gasket member is integrally connected to the switch pad at a transition line and includes an opening. The button is configured to be placed through the hole in the panel and the gasket member is configured to be repositioned relative to the switch pad along the transition line such that the opening in the gasket member is aligned with the hole in the panel and the button engages the gasket member. The flexible dome of the switch pad is configured to be aligned with the hole in the panel such that depression of the button collapses the dome of the switch pad.

Abstract: A liquid crystal display (LCD) arrangement having improved optical properties is disclosed. The LCD arrangement comprises a chip-on-glass display including a graphics area, a lightpipe, and a plurality of light emitting diodes (LEDs). The lightpipe is placed adjacent to the graphics area. The plurality of LEDs are located on the outer perimeter of the graphics area adjacent to the lightpipe.

Abstract: A rocker button assembly 10 is provided, including a button body 12 and a pivot element 14. At least one noise reducing element 20 covers a portion of the pivot element 14 and thereby reduces the generation of noise generated by the pivot element 14 as the rocker button assembly 10 rotates.

Abstract: A push button assembly 10 is provided, including a button body 12 and a pivot element 14. At least one noise reducing element 20 covers a portion of the pivot element 14 and thereby reduces the generation of noise generated by the pivot element 14 as the push button assembly 10 rotates.
