摘要:
An intelligent alarm system includes exit sign units having couplings to a smoke sensor and heat sensor for input information, a speech synthesizer and a strobe light to provide output information and a communication unit to provide communication coupling between exit sign units on a single floor and between interfloor interfaces and a central monitoring unit. The exit sign units provide at least two indications to the occupants. First a strobe light to flash at exits with sufficient intensity to draw attention to the exit and to penetrate smoke in a smoke filled hallway. Second, a speech synthesizer which provides verbal instructions to floor occupants according to the emergency situation. Each exit sign unit is operative independently of the central monitoring unit to set off a local alarm. The system is operative so that the central console unit must respond with a cancel command within a predetermined period of time to prevent the interfloor interface from communicating to all exit sign units under its supervision to set off a general floor alarm. Precise instructions may be formulated and verbalized through the speech synthesizers.

摘要:
Methods and apparatus for managing, finding and displaying objects such as digital images. Objects are tagged (“associated”) with descriptive textual and numeric data (“metadata”), and stored in a relational database from which they can be selected, sorted, and found. Tags can be defined by name, tag type, and associated attributes. Objects can be tagged by dropping a tag onto the object, or relating a database record for the tag to a database record for the object. Tagged objects can be searched for and displayed according to the degree to which their metadata matches the search criteria. Visual cues can indicate whether displayed objects match all, some but not all, or none of the search criteria. Database object distributions can be displayed as histograms or scatter plots, including timelines, calendars or maps. Object distributions can be used to search for objects or to limit search results for a previous search.
