    摘要： An improved environmental alarm system has centralized control of local sensor display capabilities displays, on the sensor itself, a variety of sensor data including sensor address, and detected levels of one or more environmental conditions. Alphanumeric characters are displayed at individual sensors in response to commands from a master microprocessor directing local sensor display content and timing. A local microcontroller within each sensor interprets the detected signal and prepares a resulting data signal that is available for downloading into the alphanumeric display in compliance with a coded message from the master microprocessor.

    摘要： Self-contained smoke detector systems each have internal self-diagnostic capabilities and function as components of an automatic fire alarm communication system implemented with a conventional two-wire alarm initiating circuit. Each system includes a microprocessor-based self-diagnostic circuit that periodically checks sensitivity of radiation sensor electronics to smoke obscuration level. By setting tolerance limits on the amount of change in voltage measured in clean air, the system can provide an indication of when it has become either under-sensitive or over-sensitive to the ambient smoke obscuration level. An algorithm implemented in software stored in system memory determines whether and provides a sensitivity fault condition signal indicating that for a time (such as 27 hours) the clean air voltage has strayed outside established sensitivity tolerance limits. The sensitivity fault condition signal includes multiple time displaced pulses, each of which having a duration and a magnitude that cooperate to diminish the probability of approximately concurrent sensitivity fault condition signals produced by multiple smoke detector systems causing the alarm initiating circuit to generate a false alarm signal.

    摘要： A smoke detector (10) has internal self-adjustment and self-diagnostic capabilities. It includes a microprocessor-based alarm control circuit (24) that periodically checks the sensitivity of a smoke sensing element (20) to a smoke level in a spatial region (12). The alarm control circuit and the smoke sensor are mounted in a discrete housing (25) that operatively couples the smoke sensor to the region. The microprocessor (30) implements a routine (50) stored in memory (32) by periodically determining a floating adjustment (FLT.sub.-- ADJ) that is used to adjust the output (RAW.sub.-- DATA) of the smoke sensing element and of any sensor electronics (40) to produce an adjusted output (ADJ.sub.-- DATA) for comparison with an alarm threshold. The floating adjustment is not greater than a maximum value (ADJISENS) or less than a minimum value (ADJSENS). Except at power-up or reset, each floating adjustment is within a predetermined slew limit of the immediately preceding floating adjustment. The floating adjustment is updated with the use of averages (NEW.sub.-- AVG) of selected signal samples taken during data gathering time intervals having a data gathering duration that is long in comparison to the smoldering time of a slow fire. The adjusted output is also used for self-diagnosis.

    摘要： A reticulated mechanical fastening laminate is disclosed. The reticulated mechanical fastening laminate includes a loop material having a regular pattern of spaced apart geometric shaped openings joined to a carrier. At least the portion of carrier to which the loop material is joined has up to a ten percent elongation. A reticulated mechanical fastening web including the loop material is also disclosed, in which the loop material is not joined to an elastic or pleated extensible carrier. A method of making the mechanical fastener constructions is also disclosed. The method includes providing interrupted slits in a loop material, with each interrupted slit interrupted by at least one intact bridging region of the slit loop material; spreading the slit loop material to provide at least one opening; and fixing of the loop material in a spread configuration.

    摘要： A fire detection system combines a CO.sub.2 gas detector with a smoke detector. Logic circuitry combines the outputs of both detectors to minimize false alarms and provide a rapid response time. In a preferred embodiment the need for periodic cleaning is reduced. In a further preferred embodiment, two alarms indicative of two different types of fires, for example flaming fires and nonflaming fires are available. A map of flaming fire and smoke may be assembled by the system to guide the firefighters. In a yet another preferred embodiment, a tentative fire alarm indication disables a local air conditioning system thereby helping to isolate and control any existing fire.
