Claims 1-6, 8-12, and 14-19 are rejected under 35 U.S.C. 103 as being unpatentable over Mammoto et al. (Mammoto – US 2013/0008787 A1) in view of Zribi et al. (Zribi – US 2017/0178481 A1).
As to claim 1, Mammoto discloses an apparatus, comprising:
a light source (Mammoto: FIG. 2 the light-emitting unit 28) in a smoke detector to emit a beam of light at a polarity of interest (Mammoto: [0048]-[0050], [0076], and FIG. 2 the light-emitting unit 28); and
a light sensor (Mammoto: FIG. 2 the light-receiving unit 30) to detect a reflection of the beam of light at the polarity of interest, the reflection created when the beam of light reflects off a smoke particle (Mammoto: [0048]-[0050], [0076], and FIG. 2 the light-emitting unit 28 and the light-receiving unit 30: In the detector 10 of the embodiment, the light-emitting unit 28 and the light-receiving unit 30 are placed in the smoke detecting section main body 24 so that an optical axis from the light-emitting unit 28 to the chamber 26 and an optical axis of light scattered by a smoke particle in the chamber 26 directed to the light-receiving unit 30 intersect at a predetermined angle in horizontal direction and at a predetermined angle even in extension direction).
Mammoto does not explicitly disclose wherein the polarity of interest based on an angle of incidence between the light source and the light sensor.
However, it has been known in the art of smoke sensor to implement wherein the polarity of interest based on an angle of incidence between the light source and the light sensor, as suggested by Zribi, which discloses wherein the polarity of interest based on an angle of incidence between the light source and the light sensor (Zribi: Abstract, [0005], [0008]-[0009], [0013]-[0014], [0038]-[0040], [0041]-[0043], and FIG. 2 the detectors 212a-212d: The detector 212a may substantially be located within a direct line of sight of light emitted by the light source 206. The detectors 212b, 212c, and 212d may be located at an angle with respect to an axis associated with the line of sight. For example, as shown in FIG. 2, detector 212b is at an angle of 50 degrees, detector 212c is at an angle of 30 degrees, and detector 212d is at an angle of 70 degrees).
Therefore, in view of teachings by Mammoto and Zribi, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to implement fire detector of Mammoto to include wherein the polarity of interest based on an angle of incidence between the light source and the light sensor, as suggested by Zribi. The motivation for this is to effectively detect a smoke condition of a smoke sensor.
As to claim 2, Mammoto and Zribi discloses the limitations of claim 1 further comprising the apparatus of claim 1, wherein the light source includes at least one of a wave plate, a light pipe (Mammoto: [0048]-[0050], [0076], and FIG. 2 the light-emitting unit 28 and the light-receiving unit 30: In the detector 10 of the embodiment, the light-emitting unit 28 and the light-receiving unit 30 are placed in the smoke detecting section main body 24 so that an optical axis from the light-emitting unit 28 to the chamber 26 and an optical axis of light scattered by a smoke particle in the chamber 26 directed to the light-receiving unit 30 intersect at a predetermined angle in horizontal direction and at a predetermined angle even in extension direction), or a filter to polarize the beam of light to the polarity of interest (Zribi: [0044]-[0045] and FIG. 2 the polarizer 226 and 232a-232d: a polarizer 226 may be associated with the light source 206.

One or more of the polarizers/analyzers 232a-232d may be used to facilitate detecting a change in the distribution of orientation/angle by passing those orientations/angles indicative of smoke and rejecting others. In this manner, the polarizers 226 and 232a-232d may effectively implement a filter).

If determined in step S3 that the CO concentration is equal to or more than 40 ppm, the process proceeds to step S4 to determine a CO alarm activation, then transmits an alarm activation signal in step S5).
Mammoto does not explicitly disclose wherein the polarity of interest based on an angle of incidence between the light source and the light sensor.
However, it has been known in the art of smoke sensor to implement wherein the polarity of interest based on an angle of incidence between the light source and the light sensor, as suggested by Zribi, which discloses wherein the polarity of interest based on an angle of incidence between the light source and the light sensor (Zribi: Abstract, [0005], [0008]-[0009], [0013]-[0014], [0038]-[0040], [0041]-[0043], and FIG. 2 the detectors 212a-212d: The detector 212a may substantially be located within a direct line of sight of light emitted by the light source 206.

One or more of the polarizers/analyzers 232a-232d may be used to facilitate detecting a change in the distribution of orientation/angle by passing those orientations/angles indicative of smoke and rejecting others. In this manner, the polarizers 226 and 232a-232d may effectively implement a filter).
As to claim 19, Mammoto and Zribi discloses the limitations of claim 14 further comprising the system of claim 14, further comprising:
a smoke detection chamber (Mammoto: Abstract, [0044], [0047]-[0051], [0070]-[0071], [0166], and FIG. 1-2 the chamber container 14: A detector includes a smoke detecting section that includes a light-receiving unit at a position at which the light-receiving unit does not directly receive light emitted by a light-emitting unit in a chamber in which a labyrinth for preventing light from directly entering from the outside and an insect net covering the rim of the labyrinth are provided, the light-receiving unit receiving light scattered by smoke flowing into the chamber); and
a plurality of baffles along a perimeter of the smoke detection chamber (Mammoto: [0044], [0047], [0070]-[0071], [0124]-[0125], FIG. 1, and FIG. 14: the detector 10 of the embodiment includes: the smoke intakes 16 formed around the chamber container 14 protruding from the center of the approximately cylindrical cover 12; the CO sensor container 18 formed by protruding a portion of the outer part of the cover 12; and the opening hole 20 open in the CO sensor container 18 to introduce CO gas into the internal CO sensor 36. This is the same as the embodiment shown in FIG. 1).
Claims 7, 13, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Mammoto et al. (Mammoto – US 2013/0008787 A1) in view of Zribi et al. (Zribi – US 2017/0178481 A1) and further in view of Piccolo, III (Piccolo – US 2015/0302727 A1).
As to claim 7, Mammoto and Zribi discloses the limitations of claim 1 except for the claimed limitations of the apparatus of claim 6, wherein the light source is to emit the beam of light with a polarity at an angle orthogonal to the polarity of the light reflected through the plurality of baffles.
However, it has been known in the art of smoke sensor to implement wherein the light source is to emit the beam of light with a polarity at an angle orthogonal to the polarity of the light reflected through the plurality of baffles, as suggested by Piccolo, which discloses wherein the light source is to emit the beam of light with a polarity at an angle orthogonal to the polarity of the light reflected through the plurality of baffles (Piccolo: Abstract, [0030]-[0031], [0035]-[0036], [0042]-[0046], and FIG. 1-2: the baffles 206-207 and the head units 112).
Therefore, in view of teachings by Mammoto, Zribi, and Piccolo it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to implement fire detector of Mammoto and Zribi, to include wherein the light source is to emit the beam of light with a polarity at an angle orthogonal to the polarity of the light reflected through the plurality of baffles, as suggested by Piccolo. The motivation for this is to implement a known alternative device to direct reflect of a light source in a smoke detector effectively detect operation conditions of the smoke sensor.
As to claim 13, Mammoto and Zribi discloses the limitations of claim 8 except for the claimed limitations of the method of claim 8, wherein instructing the light source to emit the beam of light at a polarity of interest includes instructing the light source to emit the beam of light at an angle orthogonal to the polarity of the light reflected through a plurality of baffles arranged along a perimeter of a smoke detection chamber.
However, it has been known in the art of smoke sensor to implement wherein instructing the light source to emit the beam of light at a polarity of interest includes instructing the light source to emit the beam of light at an angle orthogonal to the polarity of the light reflected through a plurality of baffles arranged along a perimeter of a smoke detection chamber, as suggested by Piccolo, which discloses wherein instructing the light source to emit the beam of light at a polarity of interest includes instructing the light source to emit the beam of light at an angle orthogonal to the polarity of the light reflected through a plurality of baffles arranged along a perimeter of a smoke detection chamber (Piccolo: Abstract, [0030]-[0031], [0035]-[0036], [0042]-[0046], and FIG. 1-2: the baffles 206-207 and the head units 112).
