Abstract: A feeding analysis system reviews collected feeding data and provides analysis of data regarding nutritive sucking, feeding, and related activity.

Abstract: A method of operating an aspirated smoke detector includes providing an ambient condition detector, establishing a first flow baseline for the detector, establishing a second, lower, flow baseline for the detector, sampling a selected airflow, and determining if the slected airflow as sampled should be compared to the first flow baseline or the second, lower, flow baseline, and responsive thereto, determining if a trouble indictor should be generated.

Abstract: A dual sensor fire detector includes a smoke sensor and a gas sensor. A source of radiant energy emits a primary beam that is formed into first and second beams. One beam is directed into a smoke sensing chamber. The other is directed to the gas sensor. Outputs from the smoke sensor and the gas sensor are combined to make a fire determination.

Abstract: An aspirated smoke detector includes a manifold coupled to a smoke sensing chamber of the smoke detector. The manifold couples ambient smoke from a plurality of locations to the smoke sensing chamber. A location of the origin of the smoke can be determined by associating a member of a plurality of a different type of smoke sensor with each of the locations. When smoke is detected in the sensing chamber, the members of the plurality can be interrogated to determine the location of the origin of the smoke in the sensing chamber.

Abstract: A smoke detector includes processing circuitry coupled to a camera. The field-of-view of the camera contains one or more targets, each having spatial indicia thereon. At least a portion of one of the targets is coated, at least in part, by an infra-red absorbing dye. The dye produces visually discernable dark areas on the coated target(s).

Abstract: A flame detector includes a sensor module, which carries a plurality of pyroelectric sensors, and a filter module which carries a plurality of replaceable filters with one filter being associated with each sensor. The modules are coupled together and carried in an exterior housing. A cover can overlay the filters to retain them in predetermined positions relative to the respective sensors.

Abstract: Regional physical information can be entered along with automatically sensed ambient condition information into regional monitoring system. Alarm decision processing can be adjusted in accordance therewith.

Abstract: A system for adjusting parameters of ambient condition detectors in a regional monitoring system is coupled to or includes fire modeling processing. Based on outputs from the processing, selected parameters of respective detectors can be adjusted to shorten detector time to alarm. As a fire condition develops, different detectors can be adjusted dynamically and in real-time.

Abstract: A device for dispensing products senses when the respective products are accessed. A signal indicative of day and time of access can be transmitted to a remote monitoring station. Received signals can be compared to a pre-established schedule.

Abstract: A sensing chamber promotes an inflow of ambient atmosphere by establishing an internal temperature gradiant. A closed loop control system can be provided to maintain the gradiant.

Abstract: A monitoring system for purposes of enhancing independent living incorporates a wearable communication device, such as a cellular telephone, in combination with a recharging base which might be coupled to a wire line telephone system. Either or both of the base station and wearable device can be in communication with sensors scattered through an individual's residence for purposes of collecting data pertaining to activities of daily living. Either or both of the wearable unit and base station could incorporate sensors responsive to physiological parameters of the resident. Both units can independently communicate with third party monitors to communicate data about, or direct immediate attention to the state of an individual using the system.
