摘要： A sensor device detects an object, in particular for optically detecting smoke particles. The sensor device contains a transmitting device for emitting transmit radiation, a receiving device for receiving receive radiation having scattering radiation that is generated by an at least partial scattering of the transmit radiation by the object, and for outputting a measurement signal indicative of the receive radiation, a signal modification device for modifying the measurement signal and for outputting a modified measurement signal, a level of the modified measurement signal increasing after the transmitting device has been switched on, and a calibration device for monitoring the modified measurement signal. The calibration device is embodied such that a reaching of a predefined signal level for the modified measurement signal can be detected and that a time interval between the switching on of the transmitting device and the reaching of the predefined signal level can be determined.

摘要： An optical smoke detector for detecting particulates in an air sample. The detector includes a detection chamber defining an enclosure for the air sample. At least one opening is in fluid communication with the detection chamber whereby the air sample can be introduced and discharged from the detection chamber. A cleaning port defines a passageway to the detection chamber from a position external to the smoke detector and a resilient valve seals the cleaning port with a substantially air-tight seal. The valve member is accessible from a position external to the smoke detector. The valve member is openable, permitting passage of air through the cleaning port into the discharge chamber, by engaging the valve member with a nozzle, such as an air nozzle mounted on a canister of pressurized air.

摘要： A compact particle sensor for detecting suspended particles includes a housing, a light source, a light receiver and a plurality of optical elements. The housing provides a test chamber and includes at least one opening for admitting particles into the test chamber, while simultaneously substantially preventing outside light from entering the test chamber. The light source is positioned for supplying a light beam within the test chamber. The plurality of optical elements are positioned to direct the light beam from the light source to the receiver, which is positioned to receive the light beam supplied by the light source.

摘要： A smoke detector includes a smoke detection chamber containing a white light LED and a light detector. The light detector detects light within at least two distinct optical wavelength bands, and generates respective signals indicative of the intensities of the detected light. An analyzer determines, based on the measured light intensities of the different wavelength bands, whether a dangerous smoke/fire condition is present.

摘要： The pulse width of a light reception pulse signal a from a light receiving device is detected, and the smoke density is detected based on a total pulse width of pulse widths per unit time period. Alternatively, the smoke density may be detected based on an integrated value of the light reception pulse signal a from the light receiving device per unit time period. Even if the flow rate of the sucked air is varied, the total light reception pulse width value per unit time period is not varied, so that the smoke density can be accurately detected.

摘要： An apparatus and a method can be used to pre-process an output signal from an ambient condition sensor. The preprocessing removes noise pulses which are not correlated with an ambient condition being sensed. Preprocessing can be carried out by comparing the present output value to a prior output value and selecting a minimum value there between. The apparatus and method can incorporate storage for two prior values and the present output value can be compared to two prior values and a minimum or a maximum of the three values selected. Additional processing can be carried out by comparing the present output value to a nominal expected clear air output value. If the present value exceeds the nominal expected output value, a minimum is selected among the present output value and one or more prior values. If the present output value is less than the nominally expected value, a maximum is selected from among the present output value and one or more prior output values.
