  • Patent number: 8870477
    Abstract: A key for a keyboard includes a keycap having a top surface configured to be contacted for pressing the key down, and having a bottom. The keycap is substantially transparent. An intermediate layer is coupled to the bottom of the keycap. The intermediate layer is translucent and includes a top and a bottom. The top of the intermediate layer faces the bottom of the keycap. A character layer is positioned between the bottom of the keycap and the top of the intermediate layer. A resilient member is coupled to the bottom of the intermediate layer. The resilient member is translucent and is configured to direct light through the intermediate layer, through the character layer, and out from the keycap. The character layer is configured to be lighted for viewing through the keycap.

  • Patent number: 7567432
    Abstract: A full-size keyboard with an integrated laptop stand. In one embodiment, the laptop stand is part of a cover for a portable keyboard, with the cover unfolding and including a pop-up stand for supporting a portable computer. The stand is thus connected to the keyboard rather than being a separate article. The cover includes electronics, such as a USB hub and ports, an MP3 player docking station, speakers, etc. A flexible hinge connects the keyboard and cover, with imbedded electrical flex connectors. A presence sensor, such as a PIR sensor, shuts off battery use by these electronics when the user is not around.
