Patent number: 11506590Abstract: Various embodiments include a scattered light smoke detector comprising: a two-color LED for emitting light of a first wavelength and a second wavelength; a photosensor spectrally matched with said two-color LED; and a control unit connected to the two-color LED and to the photosensor. The control unit is configured to control the two-color LED to emit light of the first wavelength or the second wavelength and to detect a photosensor signal of the photosensor. The control unit is further configured to analyze the photosensor signal for a first scattered radiation intensity and a second scattered radiation intensity allocated respectively to the first wavelength and the second wavelength. There is a polarizer optically connected upstream of the photosensor or downstream of the two-color LED. The polarizer polarizes light passing through at different intensities in dependence upon the respective wavelength of said light.Type: GrantFiled: September 26, 2019Date of Patent: November 22, 2022Assignee: SIEMENS SCHWEIZ AGInventors: Thomas Bachels, Mathias Staeger

Patent number: 11069226Abstract: The present disclosure relates to smoke detectors. Various embodiments may include a method for adjusting a smoke detector (adjustment method) and a device executing the method for adjusting a smoke detector (adjustment device). For example, a method for automatically adjusting a smoke detector may include: placing the smoke detector in a channel; placing a reference smoke detector into the channel; applying a flowing aerosol to the channel; gathering data from the reference smoke detector reflecting the flowing aerosol; and adjusting the smoke detector based on the data gathered from the reference detector.Type: GrantFiled: April 18, 2018Date of Patent: July 20, 2021Assignee: SIEMENS SCHWEIZ AGInventors: Martin Allemann, Thomas Bachels, Aleksandar Duric, Erwin Suter

Patent number: 9165443Abstract: A detector includes a housing with at least one window for allowing radiation to enter, at least one sensor for sensing entered radiation, a unit for processing sensor signals, and mirrors that are shaped and mounted in the housing for reflecting radiation from outside detection zones better than radiation from elsewhere, onto the sensor. Linked mirrors reflect radiation from a detection zone consecutively and each mirror in at least one linked pair is shaped and mounted in the housing so as to prevent it from reflecting radiation from another detection zone in sequence with other mirrors onto the sensor, thus optically isolating the pair from other mirrors.Type: GrantFiled: November 7, 2011Date of Patent: October 20, 2015Assignee: Vanderbilt International GmbHInventors: Thomas Bachels, Simon Daniel Fischer

Patent number: 8772702Abstract: A detector contains a housing with at least one window for allowing radiation to enter, at least one outlook sensor for sensing entered radiation, a unit for processing outlook sensor signals, and outlook mirrors that are shaped and mounted in the housing for reflecting onto the outlook sensor radiation from outside detection zones better than radiation from elsewhere. At least some of the outlook mirrors face the window and in operative orientation neighbor each other vertically. The detector further contains one or more window sensors for sensing radiation indicative of the window being masked or having been damaged and a unit for processing window sensor signals. A gap between at least two of the outlook mirrors allows radiation to travel between the window and at least one window sensor or accordant window sender or both.Type: GrantFiled: March 12, 2012Date of Patent: July 8, 2014Assignee: Siemens ABInventors: Thomas Bachels, Andreas Erni, Simon Daniel Fischer, Peter Gruber
