  • Publication number: 20050040744
    Abstract: A bezel mounting assembly includes a bezel (10), a front panel (30) defining a pair of apertures (31), and a locking device (20) attached to the bezel for securing the bezel to the front panel. The bezel includes a pair of pillars (121) and a pair of blocks (11) having a pair of posts (14). The locking device includes a pair of symmetric side plates (22) defining through slots (25) for slidably receiving the posts, a pair of resilient arms (27) extending from the side plates, an operating member (23), and a pair of catches (26). The locking device is slidably attached on the blocks, with the posts engagingly received in the through slots. The resilient arms are secured to the pillars at free ends thereof. The operating member is moved vertically so as to drive the catches to engage in and disengage from the apertures of the front panel.

  • Patent number: 6615131
    Abstract: An enhanced operating environment for an Interactive Real-Time Distributed Navigation system is disclosed. In the present invention, an enhanced operating environment is provided by improving input and output techniques in a navigation system. Disclosed are methods for reducing the number of inputs to a navigational sytstem through a wireless device. Improved input methods include methods for entering non-deterministic information to retrieve deterministic information. Also disclosed are improved output techniques including methods for pacing navigational prompts provided by a navigation system. The invention is applicable to text, graphics or audible navigation systems.

  • Patent number: 6405123
    Abstract: A method and system for interactive real-time distributed navigation employs improved techniques for input and output. The method and system may receive inputs through a wireless device. The operating environment simplifies and reduces these inputs. In some embodiments, the system receives non-deterministic input to generate deterministic information using a number of methods. The system may also employ improved output techniques including methods for pacing navigational prompts provided by a navigation system, and methods of providing navigational information to a number of users. The method and system are applicable to text, graphics or audible navigation systems.
