Abstract: Architecture that enables the preservation of label readability in a scene (e.g., map, map tiles, graphical background, etc.) by way of label orientation relative to a fixed heading on a plane or curved surface. After identifying an initial fixed heading, movement of the camera (e.g., zoom-in, zoom-out, position change, etc.) in the scene along that heading without changing the camera heading as measured relative to a fixed point does not alter label orientation. In a mapping implementation, after identifying an initial fixed camera heading over terrain of the Earth, movement of the camera (e.g., zoom-in, zoom-out, position change, etc.) in the scene without changing the camera heading as measured relative to some fixed point does not change label orientation. The orientation of labels may be changed if the heading of the camera is altered, but this change is delayed until camera movement quiesces.

Abstract: Architecture that enables the representation of labels as objects in the 3D (three-dimensional) world, with size, elevation, and orientation. Logical hierarchies in the world are represented by the placement and prominence of labels in the 3D world scene. For example, state labels are positioned higher and larger than city labels. The illusion of the label as a fixed element in the 3D model is maintained during manipulations. Additionally, movement is provided to ensure legibility, but is delayed until the user's input is quiescent. Moreover, labels along roads, for example, can be oriented to stand vertically along a curve.

Abstract: One or more techniques and/or systems are provided for providing a control user interface (UI) element. The control UI element, associated with a continuous variable, may be displayed, such as in association with a user interface (e.g., the control UI element may correspond to a view rotation variable of a map interface). The control UI element may comprise a current state indicator element configured to display a current state of the continuous variable (e.g., a compass displaying a current heading associated with the view rotation variable). The control UI element may be populated with one or more expanded control elements associated with various aspects of the continuous variable (e.g., a first expanded control element may be used to modify a right rotation aspect of the view rotation variable and a second expanded control element may be used to modify a left rotation aspect of the view rotation variable).

Abstract: A system and method are disclosed for providing fail-safe operation of a lighting system. A lighting level detector is used to obtain a baseline lighting level for a low-intensity light. If the detector measures less than the baseline level when an occupancy sensor determines the space is unoccupied, a high-intensity light is energized and an indication is provided to a user that the low-intensity light has failed. A method is also disclosed for daylighting operation of a lighting system. An occupancy sensor can have Wi-Fi functionality to enable remote configuration of the sensor. A line voltage occupancy sensor can include an interface with low voltage devices. An occupancy sensor can include an integral interface to enable an external control system to override the sensor's normal logic under emergency conditions. An occupancy sensor can include an active temperature compensation feature. An occupancy sensor can also incorporate an automatically adjustable coverage area.

Abstract: A system including an input and a controller. The input is configured to receive a switch signal from multiple different types of switches. The controller coupled to the input and can determine the type of the switch by an analysis of the switch signals received from the switch through the input.

Abstract: A method, schema and computer system for a location service provides data structures that are extensible by allowing different types of location awareness applications to retrieve and deposit location data. The method includes providing an abstract location object arranged in a schema to enable servicing a received request for a logical location of an electronic endpoint; and arranging one or more location elements within the context of the abstract location object. The location elements are configured to act as peers relative to the logical location and each location element is configured to act as a proxy relative to any other location element within the abstract location object.

Abstract: A system(s) and method(s) that facilitate managing regions of a gridded map. The regions maintain independent status and functionality while interfacing with one or more other installed regions. Grids duplicated between one or more regions do not consume system resources and/or are not removed if needed by at least one installed system. Grids are not duplicated between two or more regions and regions can be independently installed and uninstalled. The installed independent regions are maintained as a single file allowing seamless viewing between regions, which is facilitated at various levels of details.

Abstract: In an electronic document such as a map, an entity lookup system associates primitive data with entity data though parallel or corresponding grids of a primitive quad-tree and an entity quad-tree. A key is assigned to grids in the primitive quad-tree in association to particular grids in the entity quad-tree.
