摘要： A system for the collection of near real time confirmation samples is provided to quickly eliminate false positive alarms by confirming the presence or absence of a chemical agent when a monitor operating in near real time to detect the presence of that chemical agent generates an alarm. The confirmation sampling system is synchronized with the near real time monitor and the confirmation sampler and monitor draw common samples of the atmosphere of concern. In the event that the monitor generates an alarm, the confirmation sampler preserves the sample taken contemporaneously with the alarm event for separate analysis, and also takes and preserves one or more follow-on samples.

摘要： An improved fire detector unit has a plastic base defining a smoke chamber for detection of a smoke density in terms of light scattering due to the smoke particles in the smoke chamber. The base carries a circuit board mounting a light emitting element, a light receiving element, and other components forming a fire detecting circuit responsible for generating a fire warning signal based upon the detected smoke density. A metal-made electromagnetic shield is molded into the base to protect the light receiving element from electromagnetic radiation noises. The electromagnetic shield includes a ground terminal for connection with a ground line of the circuit board. In addition, terminal pins are molded into the base for electrical and physical connection of the circuit board to the base.

摘要： An integrated circuit receives as supply voltages a ground reference voltage, a logic supply voltage and a high voltage. A protection device is associated with at least one gate oxide circuit element. The protection device applies to a supply node of the circuit element either the logic supply voltage under normal conditions of operation of the integrated circuit, or the high voltage under abnormal conditions of operation of the integrated circuit for breaking down the gate oxide.

摘要： A low profile, low volume smoke chamber displaces a light source, such as a light emitting diode or laser diode, and a sensor, such as photodiode or phototransistor, to the exterior of the sensing volume. A symmetrical sensing volume results which can be coupled to symmetrical input/output ports via a generally U-shaped flow path. A two part sensing chamber housing is formed with a lower cylindrical base portion and an upper cylindrical cover portion which slideably engage one another. At least the upper cylindrical portion carries a plurality of grooves for suppression of reflections and collection of dust. An exterior end of the upper portion carries a plurality of spaced apart openings which can be filled with a screen. A reduced sensing volume in combination with a selected screen size produces an acceptable signal to noise ratio and response rate while still excluding insects and other non-smoke related particulate matter.

摘要： A self contained, wearable personal protection device that incorporates a silent security alarm feature, a smoke detector alarm feature and, optionally, the feature of providing the time of day to the wearer is disclosed. The personal protection device with these features is incorporated into a housing case that is sized to be worn about the wrist of an individual user. The personal protection device is particularly suited for use by children. The smoke detector alarm feature of the device automatically activates an audible alarm feature when smoke is detected. The silent security alarm feature is activated when the wearer pushes a button on the device. Further, the wrist worn personal protection device optionally provides the wearer with the time of day as a further incentive for the child to wear the device.

摘要： A smoke detector includes a housing defining a dark chamber admitting test atmosphere. A light receiver is disposed within the chamber. A scatter emitter is positioned within the chamber such that light strikes the receiver when reflected off particles suspended in the test atmosphere. An obscuration emitter is positioned within the chamber such that light emitted is directed to the receiver unless obstructed by particles suspended in the test atmosphere. A smoke detect signal is generated responsive to a measurement made responsive to the scatter emitter and/or the obscuration emitter.

摘要： A smoke detector (2) which operates on the scattered light principle comprises a detector chamber (4) through which a light beam (10) passes. A series of collimator discs (24, 26, 28) with apertures of progressively increasing size are associated with the light source (6) to prevent glints of light from entering the zone of the chamber at which detection occurs as a result of the presence of scattered light induced by the presence of smoke particles. A light absorber (12) at the end of the detector chamber remote from the light source uses a target surface in the form of an asymmetric cone (42) onto which the beam is directed. The design of the collimator discs and light absorber reduce the occurrence of stray light, leading to increased sensitivity.

摘要： A smoke sensor and a carbon monoxide sensor are integrated into a common detector housing. The smoke sensor is coupled to a smoke detector control integrated circuit which generates a binary output signal indicative of the presence of smoke. This signal is coupled to a programmed microprocessor in the detector housing. The carbon monoxide sensor is also coupled to the microprocessor. Outputs from the two sensors are processed substantially independently. In the presence of smoke, the smoke alarm is generated by the microprocessor. In the presence of sufficient levels of carbon monoxide, in the absence of smoke, a carbon monoxide alarm will be generated.
