Abstract: Embodiments of the invention relate to selecting a path for navigation based on path accessibility. A set of one or more paths is generated, with each path including path elements associated with path traversal. A list of preference data is stored. A set of accessible paths is dynamically calculated, which includes evaluating elements of each path of the generated set against the list of preference data. The set of accessible paths is converted into a path selection. The path selection is navigated, which includes visually displaying the path selection.

Abstract: An audio visual alarm device that can adapt to a familial look is provided. The audio visual alarm device can include an alarm housing having a footprint of a first shape, and a cover housing having a footprint of a second shape. The alarm housing can include circuitry for operating the audio visual alarm device, and the second shape can be different from the first shape. The cover housing can be configured to accommodate the alarm housing and affix to the alarm housing to give the alarm housing an appearance corresponding to the second shape. At least one portion of the alarm housing can protrude through the cover housing.

Abstract: A plastic cover covers a surface-mounted junction box which delivers wires to an alarm unit or emergency light or the like which is mounted to the cover. The cover is connected to the junction box by screws which engage threaded holes provided by the junction box. The cover can be mounted to either a single wide junction box or a double wide junction box and provides corresponding holes for connection to either box. The alarm devices can be connected to the cover directly by screws or by a combination of a single screw and a tab which is received into a slot on the cover. The cover and alarm unit together form an architecturally attractive cover for an otherwise industrial appearing junction box. When the cover is attached to the junction box, the box no longer can be seen. The covers can be color coded for a particular alarm service, such as fire, weather warnings, or other emergency conditions.
