Many gas detectors are plagued by technical challenges and limitations. For example, many gas detectors fail to produce accurate readings when the gaseous substance includes a large amount of water vapor. Summary of the Invention

[0006] In some examples, the controller component is configured to: in response to determining that the humidity level indication does not meet the humidity level threshold, transmit a second control indication to trigger the dehumidifier component to be deactivated.

[0007] In some examples, the humidity level threshold is between 40% and 60% relative humidity.

[0008] In some examples, the dehumidifier component includes a cooling element that comes into contact with the gaseous substance in the gas flow channel.

[0009] In some examples, the dehumidifier component includes a filter component disposed below the cooling element, wherein the filter component is disposed in the gas flow channel, and wherein the gas flow channel intersects at least a portion of the water channel.

[0010] In some examples, the gaseous substance in the gas flow channel includes water vapor, wherein when the dehumidifier component is activated, the controller component is configured to further activate the cooling element, wherein the cooling element is configured to reduce the temperature level in the gas flow channel, thereby causing the water vapor to condense on the surface of the filter component.

[0011] In some examples, the filter component includes one or more metal mesh structures arranged within the gas flow channel, through which the gaseous substance flows.

[0012] In some examples, the dehumidifier component further includes a water-absorbing material disposed below the filter component, wherein the water-absorbing material is disposed in the water channel and configured to absorb liquid substances from the surface of the filter component.

[0013] In some examples, the device further includes a pump, and the absorbent material is further configured to expel the water vapor from the device in conjunction with the output air of the pump.

[0014] In some examples, the absorbent material includes foam or textiles.

[0015] According to various examples of this disclosure, a method is provided. The method may include: receiving a humidity level indication from a humidity sensing component via a controller component; determining via the controller component whether the humidity level indication meets a humidity level threshold; and, in response to determining that the humidity level indication meets the humidity level threshold, transmitting a first control instruction to trigger activation of a dehumidifier component.

Detailed Implementation

[0018] Some embodiments of this disclosure will be described more fully below with reference to the accompanying drawings, in which some, but not all, embodiments of this disclosure are shown. In fact, these disclosures may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Throughout the text, similar numerals refer to similar elements.

[0019] The components shown in the accompanying drawings represent components that may or may not be present in the various embodiments of this disclosure described herein, such that embodiments may include fewer or more components than those shown in the drawings without departing from the scope of this disclosure. Some components may be omitted from one or more drawings or shown in dashed lines to make the components below visible.

[0020] The phrases “in exemplary embodiments,” “some embodiments,” “various embodiments,” etc., generally mean that a particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of this disclosure and may be included in more than one embodiment of this disclosure (importantly, such phrases do not necessarily refer to the same embodiment).

[0021] The terms “example” or “exemplary” are used herein to mean “serving as an example, for instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0022] If the specification uses words such as "may," "can," "could," "should," "will," "preferably," "possibly," "usually," "optionally," "for example," "usually," or "might" (or other such language) to include a component or feature, or if said component or feature has a characteristic, then it is not necessary to include that particular component or feature, or said component or feature does not need to have said characteristic. In some embodiments, such components or features may be optionally included or excluded.

[0023] In this disclosure, the terms “electronic coupling” or “electronic communication with” refer to two or more electrical components (e.g., but not limited to, exemplary processing circuitry systems, communication modules, input / output modules, memory, humidity sensing components, cooling components, gas detection components) and / or electronic circuits being connected by wired means (e.g., but not limited to, wires or traces) and / or wireless means (e.g., but not limited to, wireless networks, electromagnetic fields) such that data and / or information (e.g., electronic indications, signals) can be transmitted to and / or received from the electronically coupled electrical components and / or electronic circuits.

[0024] Various devices (e.g., but not limited to, photoionization detectors) can measure the concentration levels of volatile organic compounds (VOCs) in gaseous substances. The term "volatile organic compound" (or "VOC") refers to an organic compound that can have a high vapor pressure at normal room temperature (i.e., it may readily turn into a gas or vapor). Exemplary chemicals in exemplary VOCs may include, for example, but not limited to, formaldehyde, methane, and benzene. High levels of VOCs in gaseous substances (e.g., indoor or outdoor air) can have adverse effects on health and the environment. Thus, photoionization detectors can be used to measure and monitor the concentration levels of VOCs in various indoor and / or outdoor locations.

[0025] In some examples, photoionization detectors can be implemented in humid environments to detect VOC concentration levels. Water vapor in such environments can cause various technical problems and difficulties. For example, water vapor can cause photoionization detectors to malfunction and / or produce inaccurate readings.

[0026] Now for reference Figure 1 The exemplary schematic diagram depicts an exemplary photoionizing lamp 100 of an exemplary gas detection component (e.g., an exemplary photoionizing detector) according to various embodiments of the present disclosure. In particular, the exemplary photoionizing lamp 100 may include a glass tube member 101 and a window member 103.

[0027] like Figure 1As depicted, the glass tube component 101 may include a gaseous substance or a combination of gaseous substances, which may include, but are not limited to, inert gases such as argon (Ar), xenon (Xe), and / or krypton (Kr). The gaseous substance within the glass tube component 101 may be excited by any of a variety of excitation methods to generate an ultraviolet (UV) light source. For example, a voltage (e.g., alternating current (AC) voltage) may be supplied to the glass tube component 101. In such examples, the AC voltage may cause ionization of the gaseous substance within the glass tube component 101, resulting in a glow discharge. The glow discharge associated with the plasma may emit low-wavelength ultraviolet (UV) light. The UV light may be transmitted through the window component 103. In some examples, the window component 103 may include materials that enable and / or facilitate the transmission of low-wavelength UV light, including, for example, salt crystal materials. When UV light passes through the window component 103, molecules in the gaseous substance may be exposed to the UV light and detected by an exemplary gas detection component (e.g., an exemplary photoionization detector).

[0028] Specifically, exemplary gas detection components (e.g., exemplary photoionization detectors) can be configured to detect test compounds (e.g., but not limited to, VOCs in air) in a test gaseous substance. In some embodiments, exemplary gas detection components (e.g., exemplary photoionization detectors) may include an anode element (e.g., bias electrode 110) and a cathode element (e.g., signal electrode 115). In some examples, the anode element may be an electrode that attracts negatively charged electrons. In some examples, the cathode element may be an electrode that attracts positively charged electrons.

[0029] like Figure 1 As shown, a test gaseous substance (e.g., air) can flow through an exemplary gas detection component (e.g., an exemplary photoionization detector) in the direction indicated by arrow 105. The test gaseous substance may include VOC molecules 109 and non-VOC molecules 107. When VOC molecules 109 and non-VOC molecules 107 pass through the photoionization lamp 100, they may be exposed to ultraviolet light generated by the photoionization lamp 100. Figure 1 In the example shown, ultraviolet light can cause photoionization of VOC molecule 109. The term "photoionization" can refer to the phenomenon that occurs when atoms / molecules absorb light, which, at a sufficient level, causes electrons to leave, thereby generating positive ions. The ions generated during this process are collected on an electrode, thereby generating an electric current.

[0030] exist Figure 1In the example shown, photoionization of VOC molecules 109 may cause electrons to be ejected from the VOC molecules 109, forming positively charged ions. The electrons can travel to an anode element (e.g., bias electrode 110), while the positively charged ions can travel to a cathode element (e.g., signal electrode 115). When the electrons and positively charged ions are propelled to their respective electrodes, a current may be generated. Conversely, ultraviolet light may not cause photoionization of non-VOC molecules (e.g., non-VOC air) 107, and therefore, non-VOC molecules 107 do not generate a current.

[0031] In some embodiments, the generated current may be proportional to the amount of the test compound (e.g., but not limited to, VOCs in the air) in the test gaseous substance. Thus, an exemplary gas detection component (e.g., an exemplary photoionization detector) can provide a measurement of the concentration level of the test compound. For example, an exemplary gas detection component (e.g., an exemplary photoionization detector) can measure the current and convert this measurement into the concentration level of VOCs present in the air.

[0032] exist Figure 1 In the example shown, the current generated by photoionization caused by ultraviolet light from the photoionization lamp 10 is proportional to the amount of VOC molecules 109 in the air. Thus, the concentration level of VOCs can be determined at least in part based on the current generated by photoionization.

[0033] As mentioned above, many photoionization detectors can receive gaseous substances that may include water vapor. The level / amount of water vapor in the gaseous substance can be expressed as absolute humidity (AH) or relative humidity (RH). The term absolute humidity can refer to a measurement of the total mass of water vapor in a specific volume or mass of gaseous substance, and it is independent of the corresponding temperature. Absolute humidity can be expressed as grams of water per cubic meter of air (g / m³). 3 For example, the absolute humidity of air at 0°C / 32°F is approximately 5 g / m³. 3 Absolute humidity can be expressed by the following equation: in: AH = Absolute humidity (g / m³) 3 ); mH2O = mass of water vapor (g); and V net = Volume of gaseous substances (e.g., a mixture of air and water vapor) (g / m³) 3 ).

[0034] The term relative humidity can be defined as the ratio of the partial pressure of water vapor (e.g., actual vapor pressure) to the equilibrium vapor pressure of water (e.g., saturation pressure) at a given temperature. Therefore, the same amount of water vapor corresponds to higher relative humidity at a lower temperature compared to a higher temperature. Relative humidity can be expressed by the following equation: in: φ = relative humidity (%); ρ w =Vapor density (kg / m³) 3 );and ρ ws =Vapor density at saturation at actual dry-bulb temperature (kg / m³) 3 ).

[0035] As an example, if a particular air sample holds 30 grams of water vapor and can hold up to 50 grams of water vapor, the relative humidity can be expressed as 30 / 50 or 60% relative humidity.

[0036] As mentioned above, the presence of water vapor in gaseous substances can pose many technical challenges and limitations.

[0037] As an example, a gas detection component (e.g., a photoionization detector) can be calibrated using a calibration gaseous substance, and then used to generate a measurement indicating the concentration level of a test compound in the test gaseous substance (e.g., the concentration level of VOCs in ambient air).

[0038] In some embodiments, the calibration gaseous substance may have a different humidity level (e.g., AH and / or RH) than the test gaseous substance. For example, the calibration gaseous substance may not contain water vapor (e.g., a “dry” calibration gaseous substance), while the test gaseous substance may have various degrees of water vapor (e.g., varying values ​​of humidity level). As an example, water vapor may be prevalent in the test gaseous substance (e.g., ambient air). The difference in humidity level between the calibration gaseous substance and the test gaseous substance may reduce the responsiveness of the gas detection component (e.g., a photoionization detector) and may increase the measurement error rate of the gas detection component (e.g., a photoionization detector). For example, the responsiveness of the gas detection component (e.g., a photoionization detector) may be reduced by more than 50% when the test gaseous substance is associated with a low humidity level condition (e.g., a “dry” test gaseous substance that does not contain water vapor). In some embodiments, if the humidity level of the gaseous substance being tested is below 50% RH, the measurement error rate in the gas detection component (e.g., a photoionization detector) is likely to be less than 20%.

[0039] As described above, during operation, a test gaseous substance (e.g., comprising a combination of VOC and non-VOC molecules) can be contacted with a gas detection component for testing. In some embodiments, the test gaseous substance may have a high humidity level and therefore also contain a correspondingly large amount of water vapor (e.g., as indicated by measured AH and / or RH values). During testing, if a test gaseous substance comprising a large proportion of water vapor is contacted with the gas detection component, some of the water vapor may condense onto the gas detection component (e.g., a photoionization detector) and cause an increase in the amount of current generated (e.g., between bias electrode 110 and signal electrode 115). In other words, the presence of water vapor in the test gaseous substance may lead to the generation of false positive currents (e.g., false positive "leakage" currents). Therefore, a high humidity environment can provide a large amount of water vapor to the test gaseous substance and result in inaccurate current measurements of the gas detection component (e.g., between signal electrode 115 and bias electrode 110).

[0040] In another example, for a gas detection component (e.g., a photoionizer) to function optimally, its surface should be kept dust-free. As mentioned above, a specific test gaseous substance can be associated with a specific humidity level and a corresponding amount of water vapor. When the gaseous substance is delivered to the gas detection component, some of the water vapor present may absorb dust particles from the ambient air before reaching the gas detection component, and in some cases, may cause dust particles to deposit on it. During operation, when a test gaseous substance with a relatively low humidity level within the optimal range (e.g., between 40% and 60% RH) is delivered to the gas detection component (e.g., a photoionizer), a smaller total amount of water vapor will come into contact with the gas detection component (e.g., the photoionizer), and therefore dust particles are less likely to deposit on the gas detection component. However, when a test gaseous substance associated with a high humidity level and a corresponding large amount of water vapor is delivered to the gas detection component (e.g., the photoionizer), the amount of water vapor present may be large, allowing tiny, invisible dust or dirt particles absorbed by the water vapor to reach the gas detection component (e.g., the photoionizer) and deposit on it. The sensitivity and performance of gas detection components can be negatively affected by such unwanted deposits (which can accumulate over time during use). For example, the output UV light generated by an exemplary photoionizing lamp, which is proportional to the amount of VOC molecules in the air, may be weakened by the presence of dust, resulting in reduced sensitivity of the gas detection component. Furthermore, the need to maintain or frequently clean the gas detection component increases maintenance costs and the labor required from the end user.

[0041] Exemplary methods, apparatuses, and systems are provided according to various embodiments of this disclosure.

[0042] For example, this disclosure may provide an apparatus configured to receive a gaseous substance and deliver the gaseous substance from a gas inlet through a gas flow channel to discharge the gaseous substance from the apparatus via a gas outlet (e.g., causing the gaseous substance to leave the apparatus). An exemplary apparatus may include a humidity sensing component for generating a humidity level indication associated with the gaseous substance in the gas flow channel. The exemplary apparatus may receive the humidity level indication from the humidity sensing component and determine whether the humidity level indication meets a humidity level threshold. The term humidity level threshold may refer to a threshold humidity value below which the apparatus may operate with reduced or acceptable error tolerance. In response to determining that the humidity level indication meets the humidity level threshold (e.g., above the humidity level threshold), the apparatus may transmit a first control instruction to trigger activation of a dehumidifier component to reduce the temperature level in the gas flow channel by causing water vapor condensation. In response to determining that the humidity level indication does not meet the humidity level threshold (e.g., equal to or below the humidity level threshold), the apparatus may transmit a second control instruction to deactivate the dehumidifier component.

[0043] In various embodiments, the humidity level threshold may be a measurement of relative or absolute humidity associated with gaseous material in the gas flow channel. For example, the humidity level threshold may be 60% RH. As the gaseous material (e.g., moist or humid air) is conveyed along the gas flow channel, it contacts at least a portion of the dehumidifier component and flows through at least a portion of the dehumidifier component. In some embodiments, the dehumidifier component may include an arrangement of multiple components. In some embodiments, a portion of the dehumidifier may be contained within a vertical water channel. In some embodiments, the dehumidifier component may include a cooling element adjacent to the top portion of an exemplary vertical water channel, absorbent material disposed at the bottom portion of the water channel, and a filter component therebetween, the filter component being arranged such that the filter component intersects at least a portion of the gas flow channel.

[0044] For example, gaseous matter can be conveyed through an arrangement of one or more metal mesh structures defining a filter element of a dehumidifier component. In some embodiments, a cooling element can be activated to reduce the temperature level in the gas flow channel by causing water vapor to condense. In some embodiments, water vapor can be caused to condense on the surface of the filter element (e.g., one or more metal mesh structures), resulting in a decrease in the humidity level of the gaseous matter below a humidity level threshold and thus within acceptable operating limits of the device. Additionally, due to the arrangement of the dehumidifier component and the gravity acting thereon, water vapor collected by the filter element can be pulled down and conveyed downwards (e.g., along the metal mesh structure) and then absorbed by the absorbent material. In various embodiments, a pump can draw in (e.g., suck in) gaseous matter (e.g., input air) through the inlet of the gas flow channel and push the gaseous matter (e.g., output air) through the outlet of the gas flow channel. Thus, the output air of the pump, which conveys the gaseous matter from the input end to the output end of the gas flow channel, can also convey (e.g., push) the incoming water vapor from the bottom portion of the dehumidifier component (e.g., absorbent material) along the gas flow channel and discharge the water vapor from the device.

[0045] While some embodiments described herein provide exemplary photoionization detectors as examples of gas detection components, it should be noted that the scope of this disclosure is not limited to such embodiments. For example, in some examples, exemplary gas detection components according to this disclosure may take other forms.

[0046] Now for reference Figure 2 Exemplary schematic diagrams are provided depicting exemplary devices 200 according to various embodiments of the present disclosure. As shown, device 200 includes a gas flow channel 202, a dehumidifier component 209, a humidity sensing component 213, a gas detection component 205, and a pump 207.

[0047] As depicted in the figure, device 200 includes a gas flow channel 202. The gas flow channel 202 can refer to a passageway that begins at a gas inlet 201 and terminates at a gas outlet 203, through which gaseous substances (e.g., but not limited to, test gaseous substances including test compounds) can enter, flow through, and exit device 200. The gas flow channel 202 can be, or includes, for example, but not limited to, pipes, conduits, tubular structures, etc.

[0048] Refer again Figure 2Gaseous substances (e.g., test gaseous substances) can enter the device 200 through gas inlet 201. In some embodiments, gas inlet 201 may refer to an opening on the surface of the housing of the device 200. Similarly, in some embodiments, gas outlet 203 may refer to an opening on the surface of the housing of the device 200, which may be different from the opening on the surface associated with gas inlet 201. Gas inlet 201 and gas outlet 203 may be connected by gas flow channel 202 and define the start and end points of gas flow channel 202, respectively. In some embodiments, gaseous substances may be conveyed in one direction by an airflow generated by pump 207. For example, pump 207 may generate an airflow in gas flow channel 202 by drawing (e.g., sucking in) gaseous substances (e.g., input air) through gas inlet 201 and pushing the gaseous substances (e.g., output air) through gas outlet 203. Therefore, the gaseous substance is received through an opening leading to the gas flow channel 202 (e.g., gas inlet 201) and conveyed to another opening (e.g., gas outlet 203), at which it can be discharged from the device 200. In some embodiments, the pump 207 may be, or include, for example, but not limited to, a compressor, a vacuum pump, a manual pump, an electric pump, etc.

[0049] In some embodiments, after entering the device 200 through the gas inlet 201, the gaseous substance can reach the dehumidifier component 209. Figure 2 In the example shown, dehumidifier component 209 may include a water channel 215 defining a passage through which water vapor can be discharged from the device without contacting additional components within device 200, such as humidity sensing component 213 and gas detection component 205. As shown, humidity sensing component 213 and gas detection component 205 are each located downstream of dehumidifier component 209. The term downstream can refer, at least partially based on the flow direction of gaseous material within a gas flow channel, to the position of a first component in the gas flow channel relative to a second component in the gas flow channel. For example, if gaseous material flows to component A and then subsequently to component B, then component B is downstream of component A. Similarly, the term upstream can refer, at least partially based on the flow direction of gaseous material within a gas flow channel, to the position of a first component in the gas flow channel relative to a second component in the gas flow channel. For example, if gaseous material flows to component A and then subsequently to component B, then component A is upstream of component B.

[0050] Back Figure 2 After the water vapor descends through the water channel 215, the output air of the pump 207 can further push the water vapor from the bottom part of the dehumidifier component along the gas flow channel so that the water vapor is discharged from the device through the gas outlet 203.

[0051] After flowing through dehumidifier component 209, the gaseous substance is further conveyed into device 200 along gas flow channel 202 and can reach humidity sensing component 213, which is also disposed along gas flow channel 202. As shown, humidity sensing component 213 is disposed downstream of dehumidifier component 209 along gas flow channel. Subsequently, the gaseous substance can be conveyed further within device 200 along gas flow channel 202 and can reach gas detection component 205. As shown, gas detection component 205 can be located downstream of humidity sensing component 213. After reaching (e.g., flowing through) gas detection component 205, the gaseous substance can be conveyed along gas flow channel 202, for example, by output air from pump 207, until it is discharged from device 200 via gas outlet 203.

[0052] As described above, the humidity sensing component 213, located upstream of the gas detection component 205, can detect the humidity level associated with the gaseous substance in the gas flow channel 202 and can provide (e.g., transmit) a humidity level indication to the processing circuitry of the device 200. Therefore, before contacting the gas detection component 205, the processing circuitry of the device can transmit a control instruction to trigger the activation of the dehumidifier component 209. The dehumidifier component 209 can receive the control instruction and be activated to reduce the temperature level in the gas flow channel 202, for example, by causing water vapor to condense on the filter component or a portion of the dehumidifier component 209. The humidity sensing component 213 may be or include sensors capable of detecting and measuring the moisture level and / or temperature value associated with the gaseous substance. For example, the humidity sensing component 213 can detect and measure temperature, relative humidity (RH), dew point (the temperature at which the gaseous substance must be cooled to saturate with water vapor), absolute humidity (by combining relative humidity measurements with temperature measurements), and combinations thereof. The exemplary humidity sensing component 213 may be or include a hygrometer, a capacitive sensor, a resistive sensor, a thermal sensor, etc. In various embodiments, the humidity sensing component 213 communicates electronically with the controller component of the device 200, enabling it to exchange data (e.g., receive and transmit data) with the controller component of the device 200. In some embodiments, the controller component of the device 200 may process the data received from the humidity sensing component 213 (e.g., humidity level indication) to determine parameters (e.g., time period, target temperature, etc.) for activating and deactivating the dehumidifier component 209.

[0053] As described above, the device 200 also includes a dehumidifier component 209 disposed upstream of the humidity sensing component 213 and the gas detection component 205 along the gas flow channel 202. In various embodiments, the dehumidifier component 209 may include an arrangement of one or more components configured to extract, transport, and discharge liquid from gaseous substances in the gas flow channel 202.

[0054] like Figure 2 As shown, dehumidifier component 209 may include a cooling element 211. In some embodiments, cooling element 211 may be or include a semiconductor-based device, a thermoelectric cooler (TEC), a Peltier cooling module that uses the Peltier effect to generate heat flux at the junction of two different materials, or a solid-state device. An exemplary cooling element 211 may include n-type and p-type semiconductors parallel to each other (i.e., facing each other) with an interconnect therebetween. Cooling element 211 may be configured to reduce the temperature level in gas flow channel 202, thereby causing water vapor to condense on the surface of dehumidifier component 209. As shown, cooling element 211 may be positioned above / adjacent to gas flow channel 202 such that it is adjacent to the flow path of the gaseous substance. After cooling element 211 causes water vapor to condense on the surface of dehumidifier component 209, the water vapor can be conveyed through water channel 215 and discharged from device 200 (e.g., via gas outlet 203). In this way, water vapor does not continue to travel along the gas flow channel 202 with the gaseous substance and come into contact with various components of the device 200 downstream of the dehumidifier component 209 (such as, for example, humidity sensing component 213 and gas detection component 205). In various embodiments, the dehumidifier component 209 may be fixedly or removably coupled to the device 200. For example, the dehumidifier component 209 may be removable to facilitate maintenance or replacement of the components therein.

[0055] Additionally, as shown, device 200 may include a gas detection component 205 positioned downstream of dehumidifier component 209 along gas flow channel 202. If the gaseous substance flowing through gas flow channel 202 is associated with a high humidity level (e.g., a high humidity level detected by humidity sensing component 213), the device (e.g., a controller component) may transmit a control instruction to trigger activation of dehumidifier component 209 to reduce the temperature level in gas flow channel 202 before the gaseous substance reaches gas detection component 307. The gas detection component may generate a measurement indicating the concentration level of a test compound in the test gaseous substance.

[0056] In some embodiments, the gas detection component 205 may be a photoionization detector. (Refer to the above text) Figure 1As illustrated in the examples provided, the gas detection component 205 is configured to detect VOCs within the gaseous substance when at least a portion of the gaseous substance enters it (e.g., within the window member of an exemplary photoionization detector). However, other types of devices and gas detection components may be provided.

[0057] Now for reference Figure 3 Cross-sectional views of exemplary portions of a device 300 according to various embodiments of the present disclosure are provided. In particular, Figure 3 Exemplary components associated with exemplary dehumidifier component 302 are shown. Figure 3 In the example shown, the dehumidifier component 302 includes a cooling element 309, a filter component 311 including metal mesh structures 311A ​​and 311B, and a water-absorbing material 304.

[0058] As shown in the figure, the device 300 includes a gas flow channel 313, which defines a passage through which gaseous substances can enter, flow through, and exit the device 300. As shown in the figure, the gas flow channel 313 includes pipes, conduits, tubular structures, etc.

[0059] During operation, gaseous material can enter the device 300 through gas inlet 301 and be conveyed in one direction along gas flow channel 313 by an airflow generated by a pump. The gaseous material can be conveyed to dehumidifier component 302. After flowing through dehumidifier component 302, the gaseous material is conveyed to another part of the device 300, for example, to the location of humidity detection components and / or gas detection components (e.g., photoionization detectors). Subsequently, the gaseous material can be further conveyed along gas flow channel 313 before being discharged from the device through gas outlet 303, which terminates at gas outlet 303.

[0060] like Figure 3 As shown, the dehumidifier component 302 may include a filter component. As illustrated, the filter component 311 includes two metal mesh structures 311A ​​and 311B. Although Figure 3 An example of a filter component 311 comprising an arrangement of two metal mesh structures is provided; however, it should be noted that the scope of this disclosure is not limited thereto. Figure 3 The example shown. In some examples, exemplary filter component 311 may include one or more additional and / or alternative elements, and / or may be compatible with... Figure 3 The structures shown are differently structured / positioned. For example, exemplary filter component 311 may include a metal mesh structure. Alternatively, exemplary filter component 311 may include more than two metal mesh structures.

[0061] As depicted, exemplary metal mesh structures 311A ​​and 311B are in contact with the bottom side of the cooling element 309 (i.e., with the lower cooling side 309B of the cooling element 309). Furthermore, the metal mesh structures 311A ​​and 311B are arranged perpendicular to the direction of airflow through the gas flow channel 313 and are spaced apart from each other. When a voltage is applied across the cooling element 309, the flow of direct current across the junction of the semiconductor creates a corresponding temperature difference between the upper heating side 309A and the lower cooling side 309B of the cooling element 309. In some embodiments, the lower cooling side 309B is disposed on the inner surface of the gas flow channel 313 and in contact with the gaseous material flowing through the gas flow channel 313, resulting in a decrease in the temperature level in the gas flow channel 313 and causing water vapor to condense on the surface of the filter component 311 (e.g., one or more surfaces of the metal mesh structures 311A ​​and 311B). At least a portion of the dehumidifier component 302 (e.g., filter component 311, as shown) may intersect with a portion of the gas flow passage 313. For example, the filter component 311 of the dehumidifier component 302 is in the path of gaseous substances flowing through the gas flow passage 313 of the device 300. Figure 3 In the example shown, the lower cooling side 309B of the cooling element 309 is directly disposed above the metal mesh structures 311A ​​and 311B of the filter component 311, which intersect with the gas flow channel 313 of the device 300. Therefore, when gaseous material flows through the metal mesh structures 311A ​​and 311B, the gaseous material is cooled, causing water vapor to condense on the surfaces of the metal mesh structures 311A ​​and 311B.

[0062] As described above, at least a portion of the dehumidifier component 302 (e.g., the absorbent material 304) may be arranged, included, or disposed within the water channel 315. In some embodiments, the water channel 315 may be arranged perpendicularly to the gas flow channel 313. In some embodiments, the water channel 315 includes a pipe, conduit, tubular structure, etc. In some embodiments, the water channel 315 defines a passage through which extracted water vapor can be discharged from the device 300 to bypass some components of the device 300 (e.g., humidity sensing components and gas detection components). In some embodiments, as shown, the water channel 315 is a vertical channel or passage that intersects the gas flow channel 313 perpendicularly at a first location adjacent to the gas inlet 301 and a second location adjacent to the gas outlet 303 and connects the first location adjacent to the gas inlet 301 and the second location adjacent to the gas outlet 303, such that the water channel 315 defines a water passage for conveying liquid substances (e.g., water vapor) from the first location adjacent to the gas inlet 301 to the second location adjacent to the gas outlet 303. Therefore, the water channel 315 prevents water vapor from flowing through the device along the entire flow path of the gas flow channel 313.

[0063] As described above, in some embodiments, the dehumidifier component 302 includes and defines a water-absorbing material 304 at the bottom end of the water channel 315. As shown, in some embodiments, the water-absorbing material 304 completely occupies the space / cavity at the bottom end of the water channel 315. Additionally, the water-absorbing material 304 is arranged below and in contact with the filter component 311, such that gravity causes water vapor captured / collected by the filter component 311 to travel downwards, where it is absorbed by the water-absorbing material 304. The water-absorbing material 304 can be or includes any material suitable for absorbing liquid substances, such as, but not limited to, foam, fabric, textiles, etc. In various embodiments, the water-absorbing material can be configured to hold at least ten times its weight in liquid. Therefore, the liquid substance (e.g., water vapor) extracted by the filter component 311 is transported downwards through the water channel 315, bypassing other components of the device 300. Additionally, gravity can cause water vapor to descend through water channel 315, where it is absorbed by absorbent material 304 at the bottom of water channel 315. In some embodiments, the descending water vapor can be discharged from device 300 through gas outlet 303 as output air generated by the pump forces the water vapor out of device 300.

[0064] Although Figure 3 An example of an exemplary dehumidifier component 302 is provided, but it should be noted that the scope of this disclosure is not limited to this. Figure 3 The example shown is shown below. In some examples, the exemplary dehumidifier component may include one or more additional and / or alternative elements, and / or may be compatible with... Figure 3 The different structures / positions shown in the diagram.

[0065] Now for reference Figure 4 This is a schematic diagram depicting an exemplary controller component 400 of an exemplary device electronically communicating with various other components according to various embodiments of the present disclosure.

Whether configured by hardware, firmware / software methods, or a combination thereof, processing circuitry system 401 may include entities capable of performing operations according to embodiments of the invention when configured accordingly. Thus, for example, when processing circuitry system 401 is implemented as an ASIC, FPGA, etc., processing circuitry system 401 may include hardware specifically configured to perform one or more operations described herein. Alternatively, as another example, when the processing circuitry 401 is implemented as an actuator of instructions (e.g., those that may be stored in memory 407), these instructions may specifically configure the processing circuitry 401 to perform one or more algorithms and operations described herein, for example, with reference to Figure 5 Those that are discussed.

[0068] Memory 407 may include, for example, volatile memory, non-volatile memory, or a combination thereof. Although in Figure 4The memory 407 is shown as a single memory, but it may include multiple memory components. In various embodiments, memory 407 may include, for example, a hard disk drive, random access memory, cache memory, flash memory, compressed optical disc read-only memory (CD-ROM), digital versatile optical disc read-only memory (DVD-ROM), optical disc, circuitry configured to store information, or a combination thereof.

Alternatively, in at least some embodiments, memory 407 is configured to store program instructions for execution by processing circuitry system 401. Memory 407 may store information in the form of static and / or dynamic information. When the functions are performed, the stored information may be stored and / or used by controller 400.

[0069] Communication module 403 may be implemented as any device, including circuitry, hardware, computer program product, or a combination thereof, configured to receive data from and / or transmit data to another component or device. The computer program product includes computer-readable program instructions stored on a computer-readable medium (e.g., memory 407) and executed by controller 400 (e.g., processing circuitry system 401). In some embodiments, communication module 403 (like other components discussed herein) may be at least partially implemented as or otherwise controlled by processing circuitry system 401. In this respect, communication module 403 may communicate with processing circuitry system 401, for example, via a bus. Communication module 403 may include, for example, an antenna, transmitter, receiver, transceiver, network interface card, and / or supporting hardware and / or firmware / software, and is used to establish communication with another device. Communication module 403 may be configured to receive and / or transmit any data that may be stored in memory 407 using any protocol that can be used for communication between devices. Alternatively, the communication module 403 may communicate, for example, via a bus with the memory 407, the input / output module 405, and / or any other component of the controller 400.

[0070] In some embodiments, controller 400 may include an input / output module 405. Input / output module 405 may communicate with processing circuitry 401 to receive instructions input by a user and / or provide auditory, visual, mechanical, or other outputs to the user. Therefore, input / output module 405 may include supporting devices such as a keyboard, mouse, display, touchscreen display, and / or other input / output mechanisms. Alternatively, at least some aspects of input / output module 405 may be implemented on a device used by the user to communicate with controller 400.

In some embodiments, the gas detection component 413 may be similar to that described above. Figure 2 The gas detection component 205 is described. For example, the gas detection component 413 can generate a measurement indicating the concentration level of the test compound in the test gaseous substance and transmit the concentration level indication to the processing circuit system 401.

[0072] Now for reference Figure 5 A flowchart illustrating exemplary operation 500 according to various embodiments of the present disclosure is provided.

[0073] In some examples, method 500 may be implemented by a processing circuitry system (e.g., but not limited to, an application-specific integrated circuit (ASIC) or a central processing unit (CPU)). In some examples, the processing circuitry system may be electrically coupled to and / or in electronic communication with other circuitry systems of the exemplary device, such as, but not limited to, humidity sensing components, dehumidifier components, gas detection components, memory (such as, for example, random access memory (RAM) for storing computer program instructions), and / or display circuitry systems (for reproducing readings on a display).

[0074] In some examples, Figure 5One or more of the programs described herein can be implemented by computer program instructions, which can be stored in the memory (e.g., non-transitory memory) of a system employing embodiments of this disclosure and executed by the system's processing circuitry (e.g., a processor). These computer program instructions can direct the system to operate in a particular manner, causing the instructions stored in the memory circuitry to produce an article of manufacture that performs the function specified in the flowchart steps / operations. Furthermore, the system may include one or more other circuitry systems. The various circuitry systems of the system may be electronically coupled to each other and / or intermediately to transmit and / or receive energy, data, and / or information.

[0075] In some examples, embodiments may take the form of a computer program product on a non-transitory computer-readable storage medium that stores computer-readable program instructions (e.g., computer software). Any suitable computer-readable storage medium may be used, including non-transitory hard disks, CD-ROMs, flash memory, optical storage devices, or magnetic storage devices.

[0076] Exemplary method 500 begins with step / operation 501. At step / operation 501, the circuit system is processed (e.g., but not limited to, the combination discussed above). Figure 4 The processing circuitry system 401 of the controller component 400 shown receives a humidity level indication associated with the gaseous substance in the gas flow channel. In some embodiments, the humidity sensing component (e.g., but not limited to, combined with...) Figure 4 The humidity sensing component 409 shown can transmit a humidity level indication associated with gaseous substances in the gas flow channel to the processing circuit system.

[0077] Following step / operation 501, exemplary method 500 proceeds to step / operation 503. At step / operation 503, the processing circuitry determines whether the humidity level indication meets a humidity level threshold.

[0078] As described above, in some embodiments, the humidity level threshold may be a measurement of humidity (e.g., AH and / or RH) associated with gaseous substances in the gas flow channel, at which the device can operate with reduced or acceptable error tolerance. The humidity level threshold may be a predetermined and / or configurable threshold (e.g., a value between 40% and 60% RH). In some embodiments, the operator of the device may select the humidity level threshold before operating the device.

[0079] In some embodiments, if the humidity level indicated by the humidity level indicator is equal to or lower than a humidity level threshold, the processing circuitry system can determine that the humidity level indicator does not meet the humidity level threshold. For example, when the humidity level indicator does not meet the humidity level threshold, it can indicate that the device can operate with a reduced probability of error and / or increased responsiveness. As an example, if the humidity level threshold is 60% RH and the humidity level indicator indicates a humidity level of 56% RH, then the humidity level indicator does not meet the humidity level threshold because it is lower than the humidity level threshold. In another example, if the humidity level threshold is 70% RH and the humidity level indicator indicates a humidity level of 70% RH, then the humidity level indicator does not meet the humidity level threshold because it is equal to the humidity level threshold.

[0080] In some embodiments, if the humidity level indicated by the humidity level indicator is higher than a humidity level threshold, the processing circuitry system can determine that the humidity level indicator meets the humidity level threshold. For example, when the humidity level indicator meets the humidity level threshold, it can indicate that the device can operate with an increased probability of error and / or reduced responsiveness. For instance, if the humidity level threshold is 60% RH and the humidity level indicator indicates a humidity level of 70% RH, then the humidity level indicator meets the humidity level threshold because it is higher than the humidity level threshold. As another example, if the humidity level threshold is 75% RH and the humidity level indicator indicates a humidity level of 95% RH, then the humidity level indicator meets the humidity level threshold because it is higher than the humidity level threshold.

[0081] After step / operation 503, method 500 proceeds to step / operation 505. At step / operation 505, if the processing circuitry determines that a humidity level threshold is met, method 500 proceeds to step / operation 507. As another example, if the humidity level threshold is 70% RH and the humidity level indicator indicates a humidity level of 95% RH, then the humidity level indicator meets the humidity level threshold because it is higher than the humidity level threshold, and method 500 will proceed to step / operation 507.

[0082] Following step / operation 505, at step / operation 507, in response to determining that the humidity level indication meets a humidity level threshold, the processing circuitry system directs cooling to a cooling element (e.g., but not limited to, the combination discussed above). Figure 4The cooling element 411 shown transmits a first control instruction to activate the dehumidifier component. Activating the dehumidifier component may include turning on a switch connected to a power source for the cooling element in response to receiving the control instruction. The cooling element may be configured to reduce the temperature level in the gas flow channel, thereby causing water vapor to condense on the surface of the filter component (e.g., a metal mesh structure). Additionally, as described above, water vapor can pass through water channels (e.g., via the aforementioned combined...) due to the pump's output air. Figure 3 Water channel 315, shown and described, discharges from the device and accommodates at least a portion of the dehumidifier components (e.g., but not limited to, as described above). Figure 3 The absorbent material 304 shown and described.

[0083] Returning to step / operation 505, if the processing circuitry determines, for example by determining that the humidity level indicated by the humidity level indicator does not meet the humidity level threshold (e.g., by determining that the humidity level indicator is equal to or less than the humidity level threshold), then method 500 alternatively proceeds to step / operation 509. For example, if the humidity level threshold is 70% RH and the humidity level indicator indicates a humidity level of 66% RH, then the humidity level indicator does not meet the humidity level threshold because it is below the humidity level threshold, and method 500 will proceed to step / operation 509.

[0084] At step / operation 509, in response to determining that the humidity level indication does not meet the humidity level threshold, the processing circuitry system directs cooling to a cooling element (e.g., but not limited to, the combination discussed above). Figure 4 The cooling element 411 shown transmits a second control instruction to deactivate the dehumidifier component. Deactivating the dehumidifier component may include causing a switch connected to the power supply to the cooling element to turn off in response to receiving the second control instruction.

[0085] As mentioned above, water vapor can interfere with the accuracy of readings obtained by the gas detection element. Therefore, the processing circuitry can utilize a feedback loop to maintain optimal operating conditions for the gas detection element by monitoring and responding to reduce the temperature in the gas flow chamber of the device, allowing water vapor to be extracted and discharged from the device and preventing it from interacting with the gas detection element (e.g., but not limited to, as described above). Figure 2 The gas detection component 205 shown and described is in contact.

[0086] Now for reference Figure 6 Provides illustrations depicting exemplary measurements. For example... Figure 6As depicted, the x-axis represents multiple time instances. As shown in the figure, for the first line 601, the y-axis represents the humidity level (RH). As shown in the figure, for the second line 603, the y-axis also represents the concentration of compounds in gaseous substances measured in parts per million (PPM).

[0087] like Figure 6 As shown, multiple measurements 603 of compounds in a gaseous substance (e.g., the same or similar gaseous substance) captured by a gas detector fluctuate over time. Figure 6 As further shown, the detected relative humidity level 601 is captured for each of the multiple measurements indicated in the second line 603 in the figure. Figure 6 As shown, the detected relative humidity level 601 corresponds closely to each corresponding measurement of the compound in the gaseous substance (e.g., relative to its fluctuations). Therefore, Figure 6 This demonstrates how relative humidity levels affect the accuracy of measurements obtained from gas detectors.

[0088] Now for reference Figure 7 Illustrations are provided depicting exemplary measurement values ​​of exemplary devices according to various embodiments of the present disclosure. Figure 7 As depicted, the x-axis represents multiple time examples. As illustrated, the y-axis represents humidity level measurements (RH) associated with gaseous substances entering or within the exemplary device. Figure 7 As shown, the first line 701 depicts a humidity level measurement associated with a gaseous substance entering the exemplary device (e.g., near a gas inlet), which is detected upon entry. The second line 703 depicts a humidity level measurement associated with the gaseous substance when it is near a gas detection component. Figure 7 It also indicates that the humidity level threshold of the device is 705, which is 75% RH.

[0089] like Figure 7 As depicted, the humidity level of the gaseous substance entering the device (as shown on the first line 701) is higher than the humidity level of the same gaseous substance when it is adjacent to a gas detection component (as shown on the second line 703). Therefore, as shown, the device is able to reduce the amount of water vapor associated with a given gaseous substance. For example, as described above regarding... Figure 4The cooling element 411 is activated when the humidity level indication associated with the gaseous substance exceeds a humidity level threshold. As shown, in response to an input gaseous substance with a high humidity level of 95% RH, the device can control and maintain the humidity level below a humidity level threshold 705, preventing excessive water vapor from contacting the gas detection component of the device. Therefore, the responsiveness of the device is not adversely affected, and the accuracy of the gas detection measurements can be maintained.
