For example, sensors may detect presence of fire in the environment, detect motion in the environment, detect proximity of an object, determine distance to one or more objects, determine a point cloud representation of the objects in the environment, etc. In general, sensors receive signal(s) from the environment, such as visible and/or invisible optical beams, etc, in order to perform the detection and/or sensing.


A sensor may have a limited Field of View (FoV) for receiving signal(s), which may limit its detection and or sensing capability. Applicant has identified technical challenges and difficulties associated with the FoV in sensors. Through applied effort, ingenuity, and innovation, Applicant has solved problems related to address the limitation of the FoV in sensors by developing solutions embodied in the present disclosure, which are described in detail below.

Referring now to FIG. 1A, a schematic diagram illustrating a sensor 100 is presented in accordance with various embodiments of the present disclosure. In various embodiments, the sensor 100 includes an omnidirectional reflector 101. The omnidirectional reflector 101 may include a reflecting side 120 configured to collect one or more incoming beams 110 from a 360-degree first field of view (FoV) 122 and a 180-degree or less second field of view (FoV) 102. For example, the first field of view may be a horizontal field of view, and the second field of view may be a vertical field of view.


In an example, the second field of view is between 10 to 170 degrees. In an example, the second field of view is between 20 to 150 degrees. In an example, the second field of view is between 40 to 150 degrees. In an example, the second field of view is between 50 to 150 degrees. In an example, the second field of view is between 60 to 140 degrees. In an example, the second field of view is between 70 to 130 degrees. In an example, the second field of view is between 70 to 120 degrees. In an example, the second field of view is approximately 40 degrees. In an example, the second field of view is approximately 50 degrees. In an example, the second field of view is approximately 60 degrees. In an example, the second field of view is approximately 70 degrees. In an example, the second field of view is approximately 90 degrees. In an example, the second field of view is approximately 100 degrees. In an example, the second field of view is approximately 120 degrees.


In example embodiments, the incoming beam(s) 110 are any incoming signal from an environment where the sensor 100 is located. For example, the incoming beam(s) 110 are optical beams received from the environment. The optical beams may be generated by various objects in the environment, for example by fire. The sensor 100 may for example use the incoming beams to detect a presence of the fire. In various embodiments herein as used in present disclosure, the term “fire” may also refer to combustion, smoldering, burning, excessive heat, and/or flame associated with or related to a state, process, or instance of combustion in which fuel or other material is ignited and combined with oxygen, giving off light, heat, and/or flame.


In example embodiments, the incoming beams are optical beams reflected from various objects in the environment. The reflected optical beams may be a reflection of the environment and/or background lights, such as daylight, from various objects. The reflected optical beams may be a reflection of light generated by one or more light sources, located on and/or in the sensor 100 or otherwise, from various objects. In various embodiments, the sensor 100 may for example use the incoming beams 110 to detect a movement and/or appearance of a living body in any of the first or second FoVs, for example movement and/or appearance of an individual, an animal, etc. For example, a living body may emit infrared beams generally in the 8-12 μm. In example embodiments, one or more filters may pass the 8-12 μm frequency range from one or more incoming beams. If a corresponding detector detects the presence of the 8-12 μm frequency range, the sensor 100 may detect a presence of a living body in the field of view. In example embodiments, the sensor 100 may detect movement and/or appearance of a living body similar to a thermal camera.


In various embodiments, the reflecting side 120 of the omnidirectional reflector 101 includes a shape of any of a spherical, aspherical, and/or freeform reflector. For example, the shape of the reflecting side 120 includes a curvature. In various embodiments, the reflecting side 120 surrounds the omnidirectional mirror 101 and provides the 360-degree first field of view. In various embodiments, the shape of the reflecting side 120 further determines the second field of view. In example embodiments, the shape of the reflecting side of the omnidirectional mirror 101 is selected to maximize the second field of view. For example, a freedom shape for the reflecting side, such as a complex shape including any combination of parabola, aspherical, etc., is selected such that the second field of view is maximized.


In various embodiments, the reflecting side 120 of the omnidirectional mirror 101 concentrates the collected one or more incoming beams 110 using the curvature of the reflecting side 120. In the example illustration of FIG. 1, a beam is shown using solid arrows and a path the beam follows in illustrated using dashed lines. For example, a beam of the one or more incoming beams 120 has the incoming beam's path 111. For example, the incoming beam's path may be a trajectory of the incoming beam. For example, the incoming beam may follow the paths as shown by the dashed lines in FIG. 1 (and other figures in the present disclosure) as it is reflected by and/or affected by other components. For example, the dashed lines show the one or incoming beams 110 are concentrated after being reflected from the reflecting side 120.


In various embodiments, a calibration source 103 is located inside the omnidirectional reflector 101. In various embodiments, the calibration source 103 is configured to generate one or more calibration beams, for example calibration beams 301 as shown in FIG. 1B, which is a schematic diagram illustrating the beams produced by the calibration source 103 of the sensor 100 in accordance with various embodiments of the present disclosure.


In various embodiments, the sensor 100 includes a concentrating lens 104 placed at the opening of the omnidirectional reflector 101. The concentrating lens may be configured to concentrate the one or more calibration beams 301 to generate the concentrated one or more calibration beams 311. The concentrated one or more calibration beams 311 may be concentrated on a beam splitter. In various embodiments, the concentrating lens 104 may be integrated into and/or be part of the calibration source 103. In various embodiments, the calibration beams 301 may be concentrated on the beam splitter 105 with or without a need for the concentrating lens 104. In example embodiment illustrated in FIG. 1B, the calibration beams generated by the calibration source, concentrated by the concentration lens according to various embodiments, are illustrated by solid arrows.


In various embodiments, the sensor 100 includes a beam splitter 105 configured to split the collected and concentrated incoming beams 124 to a first portion of the collected and concentrated incoming beams 126 and a second portion of the collected and concentrated incoming beams 127, as for example illustrated in FIG. 1A. In various embodiments, the beam splitter 105 splits the one or more calibration beams 301, or the concentrated one or more calibration beams 311, to the first portion of the calibration beams 136 and a second portion of the calibration beams 137, as for example illustrated in FIG. 1B.


In various embodiments, the beam splitter 105 is a micro prism beam splitter. A microprism beam splitter may split a beam into two or more beams by reflecting the beam on two or more facets of each micro prism of an array of micro prisms. Therefore, the micro prism array may split the beam into two, three, or more beams, according to the number of facets. Using a micro prism splitter may however divide the intensity of the beam, hence the generated beam portions may have less intensity (inversely proportional to the number of beam portions). For example, if a microprism beam splitter splits the beam into three beams portions, each of the three split beams may have about a third of the intensity of the original beam.


In various embodiments, the beam splitter used to generate the first and second portions of the collected and concentrated incoming beams (126, 127) and/or the first and second portions of the calibration beams (136, 137) may be a plate beam splitter for example as shown in FIG. 2. FIG. 2 is a schematic diagram illustrating the sensor 100 using a plate beam splitter 412 in accordance with various embodiments of the present disclosure. In various embodiments, the plate beam splitter 412 splits a beam by reflecting one generated beam portion and passing (or transmitting through) another beam portion. The plate beam splitter may be placed orthogonal to or at an angle to a beam, hence it may generate the beam portions at various angles. In example embodiments, the plate beam splitter 412 is placed at an approximately 45 degrees angle with respect to the collected and concentrated incoming beams 124, and generates the first and second portions of the collected and concentrated incoming beams (126, 127) so that they are orthogonal to each other. In various example embodiments, the plate beam splitter may facilitate various placings of the filters, detectors, and/or other splitters for receiving the generated beam portions (such as the first and second portions of the collected and concentrated one or more incoming beams 126, 127) hence providing more flexibility in the arrangement of components and providing more compact design and spatial savings and/or efficiently for the sensor device 100.


In example embodiments, the plate beam splitter 412 is an intensity-based beam splitter that may also split a beam intensity and divide a beam into lower intensity beam portions. For example, a 50:50 beam splitter may be used that divide the intensity by half and pass (or transmit through) the totality of the wavelength rage of the incident beam to the generated beam portions. The intensity-based beam splitters may provide the advantage of flexibility in placing filters or detectors, since all the generated beam portions include the full wavelength range of the incident beam on the beam splitter.


In example embodiments, the plate beam splitter 412 is a dichroic beam splitter that splits a beam spectrally (or with respect to their wavelength range) such that the generated beam portions each have a different wavelength range, but without any significant reduction in the intensity of the generated beam portions compared with the beam incident on the plate beam splitter. Using dichroic beam splitters may have the advantage of providing the full beam intensity of the incident beam to each detector which may provide larger signal to noise ratio, better detection, and/or larger detection range for the sensor.


In various embodiments, the sensor 100 includes a first filter 106 configured to filter first beams comprising any of a first portion of the collected and concentrated incoming beams 126 and a first portion of the calibration beams 136. In various embodiments, the sensor 100 includes a first detector 108 configured to detect the filtered first beams.


In various embodiments, the sensor 100 includes a second filter 107 configured to filter second beams comprising any of a second portion of the collected and concentrated incoming beams 127 and a second portion of the calibration beams 137. In various embodiments, the sensor 100 includes a second detector 109 configured to detect the filtered second beams.


In various embodiments, the sensor 100 may include more than two filters and corresponding detectors. For example, with reference to FIG. 1A, the microprism beam splitter 105 may split the collected and concentrated incoming beams 124 to three or more portions. Each portion may be filtered using a corresponding filter and detected using a corresponding detector. In various embodiments, as for example further described in the present disclosure, other beam splitters may be used to split a beam into three or more portions, where each beam portion may be filtered and/or detected using corresponding filters and/or detectors.


In various embodiments, the first filter 106 and the second filter 107 may each allow for certain characteristics of one or more first beams and one or more second beams to pass through, respectively. The certain characteristics may characterize and/or identify one or more incoming beams of interest.


In various embodiments, the incoming beams of interest are due to and/or originate from a presence of object(s) and/or occurrence of events of interest in the environment. For example, certain levels of intensity in specific frequency and/or wavelength ranges of incoming beams may indicate a presence of fire in the environment. For example, FIG. 3 illustrates an intensity of one or more incoming beams from an environment in which a fire is present. For example, a beam intensity higher than a first threshold in the wavelength range around 0.25 μm (for example any range in 0.2-0.3 μm) indicates ultraviolet beams of interest caused by a fire. For example, a beam intensity higher than a second threshold in the wavelength range around 2.7 μm (for example any range in 2-3 μm) indicates infrared beams of interest caused by a fire. For example, a beam intensity higher than a third threshold in the wavelength range around 4.3 μm (for example any range in 3.7-4.8 μm) indicates infrared beams of interest caused by carbon dioxide.


In various embodiments, any of these beams of interests may be used to detect the presence of the fire. For example, the sensor 100 may split the collected and concentrated one or more incoming beams 124 to three portions, and each portion may be filtered using a bandpass filter corresponding to the wavelength ranges described above with respect to FIG. 3. The corresponding detectors may each detect the presence and/or determine the intensity of each of the beams of interest to determine the presence of the fire. In various embodiments, each or any combination of the wavelength ranges of interest (for example those illustrated in FIG. 3) may be selected using a dichroic beam splitter instead of or in addition to using filters. For example, when using a dichroic beam splitter for the plate beam splitter 412 in the example illustrated by FIG. 2, the dichroic beam splitter may split the incident beam to beam portions of any one or more wavelength ranges of interest. For example, the dichroic beam splitter may reflect beams in the wavelength range around 0.25 μm (for example any range in 0.2-0.3 μm) to a first detector, and pass beams in the wavelength range around 2.7 μm (for example any range in 2-3 μm) and in the wavelength range around 4.3 μm (for example any range in 3.7-4.8 μm) towards a second and/or a third detector. In various embodiments, another dichroic beam splitter may separate the beams in the wavelength range around 2.7 μm (for example any range in 2-3 μm) and beams in the wavelength range around 4.3 μm (for example any range in 3.7-4.8 μm) and direct each to a corresponding detector. In example embodiments, using dichroic beam splitter(s) may eliminate the need for using a bandpass filter corresponding to each detector, since the wavelength ranges of interest are directed to the corresponding detectors using dichroic beam splitters.


In various embodiments, the one or more calibration beams comprise characteristics similar to the incoming beam of interest, such as any of similar bandwidth, amplitude, intensity, power, energy, etc. In various embodiments, the sensor 100 uses the calibration beams having characteristics similar to a beam of interest to verify whether a corresponding detector correctly detects and/or identifies an object and/or event of interest that correspond to the beam of interest. For example, a calibration beam may be a beam with the intensity of or higher than the first threshold in the wavelength range around 0.25 μm (for example any range in 0.2-0.3 μm) that indicate ultraviolet beams of interest caused by a fire. The sensor 100 (or a controller electronically coupled to the sensor 100 as described below) may determine whether the corresponding detectors correctly detects and/or identifies a presence of a fire. In example embodiments, other calibration beams corresponding to the other wavelength ranges indicating fire, and/or having other characteristics indicating any other event and/or object of interest, and/or measurements of the objects of interest, may be used. In various embodiments, the sensor 100 is calibrated and or tuned based on the calibration process to provide acceptable detection and/or sensing.


Referring now to FIGS. 4A and 4B, schematic diagrams illustrating the omnidirectional reflector 101 is presented in accordance with various embodiments of the present disclosure.

In various embodiments, any of the first, second, and/or third filters allow the beams with characteristics corresponding to the characteristics of the beams of interests (which in turn correspond to the desired detections and/or sensing by the sensor) to pass through, as for example described with respect to sensor 100.


Referring now to FIGS. 9A, 9B, schematic diagrams from various perspectives illustrating the first dichroic beam splitter 513 and the first and second calibration sources 924 and 925 in accordance with various embodiments of the present disclosure are provided. In various embodiments, the sensors 500, 600, 700, 800 include the dichroic beam splitter 513 and the first and second calibration sources 924 and 925. In various embodiments, when some components of the sensor (for example first and second filters in the example arrangement of sensor 500 illustrated in FIG. 5) is on a line of sight from the opening 203 to one or more detectors of the sensor, it may not be practical to place the calibration source inside the omnidirectional reflector 101. The arrangement of the calibration sources on the first dichroic beam splitter 513 as for example illustrated in FIGS. 9A, 9B provides the advantage of having a line of sight from the calibration source(s) to the detector(s).


In various embodiments, as for example illustrated with respect to sensors 500, 600, 700, 800, due to the shape of the omnidirectional mirror 101, for example due to the opening 203, a center portion of the first dichroic beam splitter 513 may not receive incident beams (as for example is illustrated by the dashed beam paths in FIGS. 5, 6, 7, 8). For example, there may be a donut shaped incident area by one or more incoming beams (after any of the collection, concertation, reflection, etc.) on the first dichroic beam splitter 513. Hence, in various embodiments herein, placing the calibration source(s) in the center of the first dichroic beam splitter 513 does not block beam paths for the one or more collected, concentrated, and/or reflected incoming beams.


In various embodiments, a calibration light holder 926 is configured to hold the first and second calibration lights at a center of the first dichroic beam splitter 513.


In various embodiments, one or more electrical connectors 922 are disposed on the first dichroic beam splitter.

For example, referring to FIGS. 5-8, a first filter and/or detector holder(s) are configured to hold any of the first filter and first detector in place. For example, second filter and/or detector holder(s) are configured to hold any of the second filter and/or second detector in place. For example, third filter and/or detector holder(s) are configured to hold any of the third filter and third detector in place. For example, beam splitter holder(s) are configured to hold any of the beam splitter(s) in place. In various embodiments, the holders may be any physical connectors, such as line connectors, web connectors, wires, etc.


In various embodiments, any of the holders may block beam paths for the one or more collected, concentrated, and/or reflected incoming beams and create shadow on the first dichroic beam splitter.


In various embodiments, the one or more electrical connectors 922 are located in a shadow of the holder(s) with respect to the collected, concentrated, and/or reflected one or more incoming beams. For example, placing the one or more electrical connectors 922 in the shadow(s), prevents reducing beam energy from receiving the corresponding detector(s) hence doing so may enhance sensing and/or detection of the corresponding sensor.


Referring now to FIG. 10, a schematic diagram illustrating a calibration light holder 926 configured to hold the first and second calibration lights 924 and 925 is provided in accordance with various embodiments of the present disclosure.
