Patent Application
20230070014
This patent specification relates to an organic matter processing apparatus, and more particularly to a residential oriented apparatus and methods for the use thereof for converting organic matter to a ground and desiccated product.
Individuals, groups of people, and families living and eating in their respective residences generate resident-based organic matter that degrades into methane—a powerful greenhouse gas—without oxygen. These harmful emissions can be avoided by diverting the resident-based organic matter such as uneaten or spoiled food from landfills. One way to divert food and other organic matter from landfills is to process the food and other organic matter into a partially descicatted product using a conventional food recycler or food grinder. These conventional food recylers and food grinders, however, are not efficient in processing food and other organic matter.
The food industry (e.g., restaurants, grocery stores, etc.) has followed many traditional paths for handling food. For example, the food industry strives to prevent food from non-use or spoil by attempting to sell the food according to a first in first out method where older product is prioritized by sale. If the food is fit for consumption, such food may be provided to a food bank or charity. If the food is unfit for human consumption, but is safe for use as animal feed, the food can be used as animal feed. If the food is unsafe for human consumption and for animal feed, the food can be turned into compost. If the food is unsuitable for composting, the food may be converted into energy through anaerobic digestion (e.g., microorganisms convert the food into a biogas). Lastly, the food can be sent to a landfill if any of the other options are not viable. Each of these paths, however, require transportation of non-descicatted (and relatively heavy) food matter to the appropriate facilities. The volume and weight of the food may require use of heavy internal combustion engine trucks—thereby further contributing to greenhouse gas—to transport the food. In addition, the heavy trucks further increase wear and tear on roads and other infrastructure, and require cost for manpower and equipment.
Accordingly, what is needed is a residential or consumer oriented organic matter processing apparatus capable of efficiently and consistently rendering an end product that is curated according to specific properties to enable lightweight and lowcost shipping of the end product for use in a regulatory approved upcycling process.
Embodiments disclosed herein provide an organic matter processing apparatus and method for the use thereof to convert organic matter into a ground and desiccated product. This can be accomplished using a bucket assembly that can grind, paddle, and heat organic matter contained therein. An air treatment system is provided to treat the air interacting with the organic matter.
A further understanding of the nature and advantages of the embodiments discussed herein may be realized by reference to the remaining portions of the specification and the drawings.
In the appended figures, similar components and/or features may have the same numerical reference label. Further, various components of the same type may be distinguished by following the reference label by a letter that distinguishes among the similar components and/or features. If only the first numerical reference label is used in the specification, the description is applicable to any one of the similar components and/or features having the same first numerical reference label irrespective of the letter suffix.
The ensuing description provides exemplary embodiments only, and is not intended to limit the scope, applicability or configuration of the disclosure. Rather, the ensuing description of the exemplary embodiments will provide those skilled in the art with an enabling description for implementing one or more exemplary embodiments. It being understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the invention as set forth in the appended claims.
Specific details are given in the following description to provide a thorough understanding of the embodiments. However, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details.

A processor(s) may perform the necessary tasks.
As defined herein, an organic matter processing apparatus (OMPA) is an aero-mechanical device operative to convert OMPA input into an OMPA output using judicious combinations of physical, aero, and thermal processes including grinding, paddling, electric heating, and airflow.
OMPA input is defined herein as predominantly organic matter that is intended for processing by the OMPA. OMPA input can include food matter and/or mixed organic matter. Food matter can include consumable food items such as fats, oils, sweets such as sugars and chocolates, dairy products such as milk, yogurt, cheese, proteins such as meat (and bones thereof), poultry (and bones thereof), fish (and bones thereof), beans, eggs, and nuts, vegetables, fruits, and starches such as bread, cereal, pasta, and rice. Food matter is sometimes referred to as foodstuffs. Mixed organic matter can include paper or other fiber materials (e.g., soiled napkins or paper towels), compostable resins, compostable plastics, cellulosic materials (e.g., compostable silverware), and other non-food organic materials. OMPA input can also include other types of biodegradable matter (e.g., compostable diapers).
For many implementations, OMPA input may include food matter and/or mixed organic matter that is post-consumer, post-commercial, or post-industrial in nature, matter that if not processed according to the present teachings could be considered as waste, garbage, refuse, leavings, remains, or scraps. By way of example, food that is leftover on a child's dinner plate, and not in suitable condition or quantity to be stored and served later as leftovers, can represent one example of OMPA input. As another example, items such as potato peels, apple cores, cantaloupe rinds, broccoli stumps, and so forth, and similar organic materials that are spun off from the food preparation process, can represent other examples of OMPA input.
OMPA output is defined herein as processed organics derived from transformation of organic matter processed by the OMPA to yield a ground and selectively desiccated product. The processed organics can be a substantially desiccated product having water content ranging between 0.1 and 30 percent of total weight, between 5 and 25 percent of total weight, between 5 and 20 percent of total weight, between 1 and 15 percent of total weight, between 5 and 15 percent of total weight, between 10 and 15 percent of total weight, between 10 and 20 percent of total weight, between 15-20 percent of total weight, or between 10 and 25 percent of total weight. Alternatively, the processed organics can be a substantially desiccated product having water content of less than 15 percent of total weight, less than 10 percent of total weight, or less than 5 percent of total weight. The processed organics can exist as granulated or ground media. One type of processed organics can be FOOD GROUNDS™.
As defined herein FOOD GROUNDS' refers to an OMPA output characterized as having a minimum nutritional value. FOOD GROUNDS™ can be derived from OMPA input comprised of a minimum percentage of food matter such that the FOOD GROUNDS' OMPA output has the minimum nutritional value. The minimum percentage of food matter can ensure that the FOOD GROUNDS' OMPA output attains at least the minimum nutritional value. For example, a higher nutrient value OMPA output can be more readily obtained from food matter than from mixed organics such as fiber materials and cellulosic materials.
As defined herein, an OMPA output processor repurposes the OMPA output for a commercial purpose. For example, the OMPA output can be used as feed or feedstock for feed for animals or fish. In some embodiments, an OMPA output processor that receives FOOD GROUNDS' may produce a derivative product having a higher intrinsic value (e.g., nutritional, monetary, or both nutritional and monetary) than a derivative product produced primarily from mixed organics.
As defined herein, non-processed matter refers to matter that is not intended for processing by an OMPA or an OMPA output processor. Non-processed matter is not an OMPA input or an OMPA output. An example of non-processed matter can include inorganic matter such as, for example, metals, plastics, glass, ceramics, rocks, minerals, or any other substance that is not linked to the chemistry of life. Another example of non-processed matter can be yard waste such as grass clippings, leaves, flowers, branches, or the like. In very general terms, non-processed matter can refer to the garbage or waste that a resident or business disposes in a conventional trash bin for transport to a landfill processor, a recycle bin for transport to recyclables processor, or a yard waste bin for transport to a yard waste processor.
In one embodiment, the OMPA is designed to be used primarily in a residential context (e.g., in single family homes, townhouses, condos, apartment buildings, etc.) to convert residential based OMPA input into residential sourced OMPA output. Converting residential generated OMPA input to OMPA output can have a net positive effect in the reduction of methane and space occupied by landfills or compost centers by redirecting the OMPA input and the OMPA output thereof away from traditional reception centers of such material. Moreover, because the OMPA is user friendly, aesthetically pleasing, energy efficient, clean, and substantially odor free, the OMPA provides an easy to use platform for the residential sector to handle OMPA input (e.g., food scraps, etc.), thereby making the decision on what to do with residential based OMPA input an easier one to handle. The OMPA can convert OMPA input into FOOD GROUNDS overnight, where the FOOD GROUNDS are substantially odorless, easily transportable, and shelf-stable. The FOOD GROUNDS can remain in the OMPA until it is full, at which point the FOOD GROUNDS are removed and transported to an OMPA processing facility, which may convert the FOOD GROUNDS into a higher value food product (e.g., animal feed). It should be understood that OMPAs can be used to serve entire communities, cities, and industries. Use of OMPAs in these other sectors, as well as the residential sector, can result in diversion from landfills and further serve a goal of preventing OMPA input from becoming waste in the first place by converting it into usable products that can be used to enable more resilient, sustainable food systems.
Instructions for operating OMPA 100 may be stored in a memory 108. The memory 108 may be comprised of any suitable type of storage medium, such as static random-access memory (SRAM), dynamic random-access memory (DRAM), electrically erasable programmable read-only memory (EEPROM), flash memory, or registers. In addition to storing instructions that can be executed by the controller 110, the memory 108 can also store data that is generated by OMPA 100. For example, values generated by one or more sensors 128 included in OMPA 100 may be stored in the memory 108 in preparation for further analysis, as further discussed below. As further discussed below, these values may relate to characteristics (e.g., humidity or temperature) of the air traveling through OMPA 100, and insights into the OMPA input contained in the processing chamber 106 can be gained through analysis of these values. Note that the memory 108 is merely an abstract representation of a storage environment. The memory 108 could be comprised of actual integrated circuits (also referred to as “chips”). When executed by a controller 110, the instructions may specify how to control the other components of OMPA 100 to produce OMPA output from OMPA input in the processing chamber 106. The controller 110 may include a general purpose processor or a customized chip (referred to as an “application-specific integrated circuit” or “ASIC”) that is designed specifically for OMPA 100.
Generally, OMPA 100 is able to operate on its own. Assume, for example, that OMPA 100 determines that OMPA input has been deposited into the processing chamber 106 based on measurements output by a weight sensor (also referred to as a “mass sensor”), as further discussed below. In response to such a determination, OMPA 100 may initiate processing of the OMPA input. Note, however, that the OMPA input need not necessarily be processed immediately. For example, OMPA 100 may not dry and then grind the OMPA input until a given criterion (e.g., time of day, weight of OMPA input, etc.) or combination(s) of various criteria is/are satisfied.
While OMPA 100 may be able to operate largely, if not entirely, on its own, there may be some situations where input from a user will be helpful or necessary. For example, the user may want to indicate when processing should be temporarily halted so that additional OMPA input can be added to the processing chamber 106. As another example, the user may to request that an operation be initiated or halted. For instance, the user could opt to initiate a “drying cycle” if the ambient environment is expected to be vacant, or the user could opt to halt a “grinding cycle” if the ambient environment is expected to be occupied. The various cycles of OMPA 100 are discussed in greater detail below.
As shown in
Some embodiments of OMPA 100 are able to communicate with other electronic devices via wireless communication channels. For example, a user may be able to interact with OMPA 100 through a control platform (not shown) that is embodied as a computer program executing on an electronic device. The control platform is discussed in greater detail below with reference to
OMPA 100 may include a power interface 118 (also referred to as a “power port” or “power jack”) that is able to provide main power for the drying and grinding functionality, as well as power for the other components of OMPA 100, as necessary. The power interface 118 may allow OMPA 100 to be physically connected to a power source (e.g., an electrical outlet) from which power can be obtained without limitation. Alternatively, the power interface 118 may be representative of a chip that is able to wirelessly receive power from the power source. The chip may be able to receive power transmitted in accordance with the Qi standard developed by the Wireless Power Consortium or some other wireless power standard. Regardless of its form, the power interface 118 may allow power to be received from a source external to the durable housing 102. In addition to the power interface 118, OMPA 100 may include a power component 120 that can store power received at the power interface 118. The power component 118 could advantageously be useful to maintain some or all operations (e.g., the state of communications and functionality of electronic components) in the event of a power outage. Examples of power components include rechargeable lithium-ion (Li-Ion) batteries, rechargeable nickel-metal hydride (NiMH) batteries, rechargeable nickel-cadmium (NiCad) batteries, and the like.
In order to produce an OMPA output from OMPA input, OMPA 100 (and, more specifically, its controller 110) may control one or more drying mechanisms 122A-N and one or more grinding mechanisms 124A-N. The drying mechanisms 122A-N are discussed in greater detail below with reference to
Moreover, air may be drawn from the ambient environment into the durable housing 102 and then expelled into the processing chamber 106 so as to help desiccate the OMPA input contained therein, as further discussed below with reference to
Other components may also be included in OMPA 100. For example, sensor(s) 128 may be arranged in various locations throughout OMPA 100 (e.g., along the path that the air travels through OMPA 100). The sensor(s) 128 may include a proximity sensor that is able to detect the presence of nearby individuals without any physical contact. The proximity sensor may include, for example, an emitter that is able to emit infrared (IR) light and a detector that is able to detect reflected IR light that is returned toward the proximity sensor. These types of proximity sensors are sometimes called laser imaging, detection, and ranging (LiDAR) scanners. Alternatively, the presence of an individual may be inferred based (i) whether sounds indicative of the user are detectable (e.g., by a passive microphone or an active sonar system) or (ii) whether an electronic device associated with the user is detectable (e.g., by the communication module 116).
OMPA 100 may adjust its behavior based on whether any individuals are nearby. For instance, OMPA 100 may change its operating state (or simply “state”) responsive to a determination that an individual is nearby. As an example, OMPA 100 may stop driving the grinding mechanisms upon determining that someone is located nearby. Thus, OMPA 100 could intelligently react to changes in the ambient environment. Over time, outputs produced by the proximity sensor (plus other components of OMPA 100) could be used to better understand the normal schedule of individuals who frequent the physical space in which OMPA is situated.
In some embodiments, OMPA 100 includes an ambient light sensor whose output can be used to control different components. The ambient light sensor may be representative of a photodetector that is able to sense the amount of ambient light and generate, as output, values that are indicative of the sensed amount of ambient light. In embodiments where the control output mechanism 114 is a display panel, the values output by the ambient light sensor may be used by the controller 110 to adjust the brightness of the display panel.
One core aspect of OMPA is its ability to desiccate OMPA input that is deposited into the processing chamber. By removing moisture from the OMPA input through a judicious application of heating, grinding, mixing, and airflow according to the teachings herein, the OMPA can substantially halt decomposition of the OMPA input and produce a stable mass of dried-and-grinded OMPA input (hereinafter “OMPA output” or “end product” or simply “product”). This can be accomplished by directing an airflow through the processing chamber that causes the OMPA input to become increasingly dry in a predictable manner.
As shown in
As shown in
Accordingly, the first fan may draw air through the opening(s) 206 in the exterior surface of the lid 204 and then blow the air downward toward the OMPA input to create a turbulent airflow (also referred to as a “turbulent airstream”). This turbulent airflow may create small vortices inside the processing chamber 210 that ensure the air continues to move across the surface of the OMPA input.
In the embodiment shown in
When in operation, air can be removed from the processing chamber 210 through a used-air intake vent (not shown) in an exhaust hood that is located beneath a bezel 212. The intake vent is further discussed below with reference to
As further discussed below, a user may need to remove the bezel 212 in order to remove the processing chamber 210 from the durable housing 202. To remove the bezel 212, the user may grasp a structural feature 220 (referred to as a “lip”) that allows the bezel 212 to be readily removed by hand. The structural feature 220 may also serve other purposes. For example, the structural feature 220 may accommodate a locking mechanism 222 that extends downward from the lid 204 into the durable housing 202. After the locking mechanism 222 extends into the durable housing 202, a latch (e.g., driven by a solenoid) may secure the locking mechanism 222 in place. This may be helpful to restrict access when, for example, the OMPA 200 is operating at high intensity and contents of the processing chamber 210 are hot.
Removal of the bezel 212 may expose the exhaust hood as mentioned above.
At a high level, the exhaust hood 302 may be designed to guide or direct air from the processing chamber 306 through the used-air intake vent for treatment and then release into the ambient environment. A filter 304 may be installed in the used-air intake vent to prevent large fragments of OMPA input or product from entering the odor treatment system. This filter 304 may be removable. Accordingly, a user may be able to remove the filter 304 (e.g., for cleaning purposes), or the user may be able to replace the filter 304.
First, the air is guided through a photolysis chamber 402. In the photolysis chamber 402, the air is exposed to light emitted by a light source 404 that is meant to cause the decomposition or separation of odor-causing molecules. The light source 404 may be, for example, an ultraviolet (UV) bulb or UV light-emitting diode (LED).
Second, the air is guided through a dry media chamber 406. In the dry media chamber 406, the air is exposed to dry media that is meant to trap odor-causing molecules through a process referred to as adsorption. Examples of dry media include charcoal, coconut shell carbon, and manganese dioxide. In addition to acting as an odor destructor, the dry media may also act as an ozone destructor. Ozone may be generated by the light source 404 in the photolysis chamber 402, and the dry media may help to destroy that ozone.
In some embodiments, the durable housing includes a pivotable door that permits access to the dry media chamber 406. By opening the pivotable door, a user may be able to easily replace the dry media in the dry media chamber 406. For example, the user may remove existing canisters and then reinstall new canisters that have loose granules, disks, or other particulates of the dry media stored therein. Such a design allows the dry media to be replaced whenever necessary.
Following treatment in the dry media chamber 406, the air may rise upward through the vertical pillar along the rear side of the OMPA 400 that acts as a plenum. Then, the air can be expelled into the ambient environment through opening(s) located near the upper end of the vertical pillar as discussed above with reference to
Accordingly, air may initially be drawn through a used-air intake vent 412 into a channel 408 by a second fan 410 (also referred to as a “blower fan”) that is located in or near the channel 408. The used-air intake vent 412 is the same used-air intake vent as mentioned above with reference to
The first fan included in the lid of OMPA 400 and the second fan 410 situated in the odor treatment system of the OMPA 400 may have variable speeds. Accordingly, a controller (e.g., controller 110 of
In order to gain insights in the nature of the air as it travels through OMPA 400, one or more sensors may be located along the route indicated by the trace.
Because the sensors are located along the route indicated by the trace, the odor treatment system may be able to operate as a closed loop system. The term “closed loop system,” as used herein, is meant to describe a system that is able to dynamically adjust its activities based on feedback to achieve a desired goal. For instance, measurements generated by VOC sensors located along the route indicated by the trace may influence how a controller (e.g., the controller 110 of
While sensors could be located at various positions along the route, sensors generally should not be installed in the photolysis chamber 402. As mentioned above, the light source 402 located in the photolysis chamber 402 may generate ozone as it emits light. This ozone can have a significant oxidative effect on various sensors. As such, sensors are generally not installed in the photolysis chamber 402.
One or more sensors could also be installed inside the processing chamber, for example, to measure characteristics of the air above the OMPA input (i.e., air in the “headspace” of the processing chamber), For example, sensors could be located along the interior surface of the lid, or sensors could be located along the interior surface of the processing chamber.
Additional sensors could also be located along the route indicated by the trace shown in
Another core aspect of the OMPA is providing a processing chamber that not only allows OMPA input to be processed in a consistent, predictable manner, but is also easy to use by various individuals.
Generally, the bucket 502 is designed so that, when installed in the durable housing, OMPA input can be easily deposited by simply opening the lid of the OMPA. Normally, the bucket 502 includes an aperture 504 along its top end that is sized to allow for various forms of OMPA input. In some embodiments, the aperture 504 has a rectangular form that is 200-500 millimeters (mm) (7.87-19.68 inches) in length and 150-300 mm (5.90-11.81) in width. For example, the aperture 504 may have a length of roughly 350 mm (13.78 inches) and a width of roughly 200 mm (7.87 inches). Meanwhile, the bucket 502 may have a roughly prismatic form with a length of 250-500 mm (9.84-19.68 inches), a width of 100-300 mm (3.94-11.81 inches), and a height of 150-350 mm (5.90-13.78 inches). For example, the bucket 502 may have a length of roughly 320 mm (12.60 inches), a width of roughly 195 mm (7.68 inches), and a height of roughly 250 mm (9.84 inches).
Moreover, the bucket 502 may be designed to be easily washable (e.g., in a dishwasher). Thus, the bucket 502 may be comprised of one or more durable materials that can withstand prolonged exposure to OMPA input in various states (e.g., moist and dry), as well as repeated washings. Examples of durable materials include plastics, ceramics, metals, and biocomposites. The term “biocomposite,” as used herein, may refer to a composite material formed by a matrix (e.g., of resin) and a reinforcement of natural fibers. Biocomposites may be well suited because the matrix can be formed with polymers derived from renewable resources. For example, fibers may be derived from crops (e.g., cotton, flax, or hemp), wood, paper, and the like. This makes biocomposites an attractive option since the benefits (e.g., a focus on renewability and recyclability) align with those offered by the OMPA.
As shown in
The grinding mechanisms 608A-N can be driven in such a manner that an appropriate amount of grinding occurs. In some embodiments, the appropriate amount of grinding is predetermined (e.g., programmed in memory of the OMPA). In other embodiments, the appropriate amount of grinding is determined dynamically based on a characteristic of OMPA input in the bucket 602. For example, the appropriate amount of grinding may be based on the amount of OMPA input (e.g., as determined based on measurements output by a mass sensor) contained in the bucket 602. As another example, the appropriate amount of grinding may be based on the amount of resistance that is experienced by the grinding mechanisms 608A-N. Generally, dried OMPA input that has been at least partially ground will offer less resistance than wet OMPA input or dried OMPA input that has not been ground.
As the central rod 606 rotates, the grinding mechanisms 608A-N may also rotate. Generally, the grinding mechanisms rotate at a rate of 1-10 rotations per minute (RPM), at a rate of 1-2 RPMs, or 1.6 RPMS. This rotating action may cause OMPA input located near the bottom of the bucket 602 to be brought toward the top of the bucket 602, such that all OMPA input contained in the bucket 602 is occasionally exposed to the downward airflow emitted from the lid.
The grinding mechanisms 608A-N may not provide sufficient shear on their own to break apart more solid OMPA input. Examples of solid OMPA input include bones, raw produce, and the like. To address this issue, the bucket 602 may include one or more stationary blades 610A-N that can work in concert with some or all of the grinding mechanisms 608A-N. Assume, for example, that the processing chamber 600 includes at least one paddle and at least one two-prong rotating blade. In
Generally, more than one type of grinding mechanism is included in the processing chamber 600. For example, paddles and rotating blades could be arranged in an alternating pattern across the width of the bucket 602 so provide different functionalities. While the paddles may have limited usefulness in terms of grinding OMPA input, the paddles may be useful in churning OMPA input so that wetter material rises toward the top of the bucket 602. Accordingly, some “grinding mechanisms” may be primarily responsible for cutting OMPA input into smaller fragments while other “grinding mechanisms” may be primarily responsible for mixing the OMPA input to promote desiccation.
In
Grinding mechanisms (and the power available to those grinding mechanisms) may govern the types of OMPA input that can be handled by a given OMPA. Generally, stronger grinding mechanisms in combination with more power will allow heavier duty OMPA input (e.g., bones) to be handled without issue. Accordingly, different embodiments of OMPA could be designed for residential environments (e.g., with less power and weaker grinding mechanisms) and commercial environments (e.g., with more power and stronger grinding mechanisms).
In some embodiments, the bucket 602 includes a thermally conductive base portion 612 that is responsible for conveying heat to the OMPA input. Normally, the thermally conductive base portion 612 may extend up the longitudinal sidewalls of the bucket 602 that are parallel to the central rod 606. In embodiments where the thermally conductive base portion 612 is responsible for heating the OMPA input, the thermally conductive base portion 612 may extend up the longitudinal sidewalls roughly 40-70 percent of their height. In embodiments where the thermally conductive base portion 612 is responsible for heating the OMPA input and air in the “headspace” of the processing chamber 600, the thermally conductive base portion 612 may extend up the longitudinal sidewalls roughly 70-90 percent of their height.
When the bucket 602 is installed within the durable housing, the thermally conductive base portion 612 may be electrically connected to a heating element (e.g., a resistive heating element in the form of a coil) that is located in the durable housing.
A mass sensing system may be incorporated into the OMPA so that mass measurements can be made throughout an organic matter processing cycle or anytime the bucket is present within the OMPA. The mass sensing system may include one or more mass sensors such as, for example, piezoelectric mass sensors. Alternatively, the mass sensing system may include a strain gauge mass sensor.
One or more mass sensors are normally located along the bottom of the OMPA (e.g., on each “foot” where the OMPA terminates along a substantially planar level). These mass sensor(s) can be used to measure the weight of the OMPA (and thus, the weight of contents of the processing chamber). However, because the bucket 602 can be removable installed within the durable housing, mass sensors could additionally or alternatively be located along the bottom of the bucket 602. As an example, a mass sensor may be located on each “foot” of the bucket 602. Regardless of location, the mass sensor(s) included in the OMPA may continually or periodically output measurements that can be used to calculate, infer, or otherwise establish the total weight of the bucket 602 (including any OMPA input stored therein). These measurements can be communicated to a controller (e.g., controller 110 of
As shown in
This gradual tapering along one end may also create a space 810 along one end of the bucket 802 in which components can be installed. For example, the gears that are responsible for driving the central rod that extends through the cavity may be located in this space 810. In addition to conserving valuable space within the bucket 802 (and OMPA as a whole), locating the gears in the space 810 will also add weight to one end of the bucket 802. This added weight may make it easier for the user to rotate the bucket 802 along that end to empty contents via the lip 808.
An important aspect of increasing adoption is that the OMPA should be easily deployable and operable. The component with which many users will interact most frequently is the lid (e.g., lid 204 of
As an example, a user may not only be able to open the lid with her hands, but also by interacting with an electro-mechanical pedal switch that is accessible along the front side of the OMPA.
As another example, the lid may be controllably lockable, for example, via a damped mechanism with a smooth spring-loaded retraction. Assume, for example, that the OMPA is performing high intensity processing where the processing chamber is heated. In such a situation, the lid may remain locked so long as the temperature of the processing chamber (or its contents) remains above a threshold (e.g., programmed in memory). This locking action may serve as a safety mechanism by ensuring that a user cannot easily access the interior of the OMPA under unsafe conditions. Note, however, that the user may still be able to override this locking action (e.g., by interacting with an input mechanism accessible along the exterior of the OMPA).
As another example, air may be “sucked” downward whenever the lid is opened, thereby preventing odors from escaping into the ambient environment. This action may be particularly helpful in preventing odors from escaping the OMPA when the lid is opened mid-cycle (i.e., while the OMPA input is being dried or ground). This action can be initiated by a controller based on one or more outputs produced by a sensor that is located proximate to where the lid contacts the durable housing when in the closed position. For example, a sensor could be located along the periphery of the lid, and its output may be indicative of whether the lid is adjacent to the durable housing (i.e., in the closed position). As another example, a sensor could be located along the periphery of the durable housing, and its output may be indicative of whether the lid is adjacent to the durable housing (i.e., in the closed position).
As another example, the lid may be intelligently controlled based on the intent of a user as inferred by the OMPA. Assume, for example, that the user either partially opens the lid by pivoting the lid roughly 30-75 degrees with respect to its original location or softly presses on a pedal switch (e.g., pedal switch 904 of
Similarly, the OMPA may control how quickly the lid closes based on the intent of the user. If the OMPA infers that the user is interested in performing a short-duration activity, the OMPA may maintain the lid in a given position (e.g., at the first angle) for a first amount of time. If the OMPA infers that the user is interested in performing a long-duration activity, the OMPA may maintain the lid in another given position (e.g., at the second angle) for a second amount of time. The first amount of time may be 2-10 seconds, while the second amount of time may be 10-60 seconds.
Over time, the OMPA may cycle between various states to process OMPA input. As mentioned above, the OMPA may be able to convert OMPA input into a relatively stable product (e.g., food grounds) by drying and grinding the OMPA input. The control parameters for drying or grinding the OMPA input may be dynamically computed (e.g., by the controller 110 of
As mentioned above, the OMPA may be able to intelligently cycle between different states to process OMPA input. Six different states are described in Table I. Those skilled in the art will recognize, however, that embodiments of the OMPA may be able to cycle between any number of these states. For example, some OMPAs may only be able to cycle between two, three, or four of these states, while other OMPAs may be able to cycle between all six states.
The OMPA may rely on a single target criterion or multiple target criteria to determine when to cycle between these states. The target criteria could be programmed into the memory of the OMPA, or the target criteria could be specified by a user (e.g., through an interface generated by a control platform). Examples of target criteria include moisture level, temperature, and weight. Using moisture level as an example, there may be multiple preset moisture levels (e.g., 10, 20, 30, and 40 percent) from which the target criterion could be selected (e.g., based on the nature of the OMPA input). The OMPA may not measure moisture of the OMPA input, but can instead predict or infer the moisture based on, for example, the humidity of air traveling through the OMPA and the weight of OMPA input. The OMPA could also rely on the average times for completion of these states. Assume, for example, that the OMPA receives input indicative of a request to process OMPA input deposited into the processing chamber. In such a situation, the OMPA may determine when to schedule the various states based on (i) how long those states have historically taken to complete and (ii) the weight of the OMPA input, among other factors. For example, the OMPA may attempt to schedule high intensity processing to be completed overnight as the grinding mechanisms may operate at a noise that might disturb nearby individuals.
As mentioned above, the durations of these states can be dynamically determined based on, for example, analysis of outputs generated by sensors housed in the OMPA. However, the durations of these states are predefined—at least initially—in some embodiments. For example, high intensity processing may be programmed to occur for a certain amount of time (e.g., 4, 6, or 8 hours), and burst grind may be programmed to occur for a certain amount of time (e.g., 30 seconds, 5 minutes, 30 minutes) whenever new OMPA input is added. Those skilled in the art will also recognize that the duration of some states could be dynamically determined, while the duration of other states could be predefined. As an example, the OMPA may continue performing high intensity processing until the target criteria are achieved. However, whenever new OMPA input is added, the OMPA may cycle to burst grind for a certain amount of time (e.g., 30 seconds, 5 minutes, 30 minutes) before reverting back to its previous state.
In some situations, it may be desirable to remotely interface with an OMPA. For example, a user may want to initiate high intensity processing if she is not at home and does not expect to return home for an extended duration (e.g., several hours). This could be done through a control platform that is communicatively connected to the OMPA. Thus, the user may be able to interact with the OMPA through the control platform. Through the control platform, the user may also be able to view information regarding the OMPA (e.g., its current state, average duration of each state, how much OMPA input has been processed over a given interval of time, current weight of the bucket and its contents) through interfaces that are generated by the control platform.
Users may be able to interface with the control platform 1102 via interfaces 1106. For example, a user may be able to access an interface through which information regarding OMPA 1112 can be viewed. This information may include historical information related to past performance (e.g., total pounds of OMPA input that has been processed), or this information may include state information related to current activity (e.g., the current state of OMPA 1112, an indication of whether OMPA 1112 is presently connected to the electronic device 1104, an indication of whether OMPA 1112 is presently locked). Thus, a user may be able to educate herself on the OMPA and its contents by reviewing content posted to interfaces generated by the control platform 1102.
Moreover, a user may be able to access an interface through which instructions can be provided to OMPA 1112. Said another way, the user may be able to specify, through the control platform 1102, when or how OMPA 1112 should process OMPA input stored therein. As an example, the OMPA 1112 may initially be configured to perform high intensity processing between 10 PM and 8 AM under the assumption that its ambient environment will generally be devoid of individuals during that timeframe. However, the user may be able to adjust aspects of setup or operation of OMPA 1112 through the control platform 1102. For instance, the user could specify that high intensity processing should not begin until 2 AM, or the user could specify that high intensity processing should not end after 6 AM.
A user could also program, through the control platform 1102, a preference regarding the weight at which to empty the processing chamber of OMPA 1112. On its own, the processing chamber may weigh 8-10 pounds. The total weight of the processing chamber (including its contents) can quickly become unwieldy for some users, such as elderly individuals and juvenile individuals. Accordingly, the control platform 1102 may permit users to define a weight at which to generate notifications (also referred to as “alarms”). Assume, for example, that a user indicates that the total weight of the processing chamber (including its contents) should not exceed 15 pounds through an interface generated by the control platform 1102. In such a scenario, the control platform 1102 may monitor mass measurements received from OMPA 1112 and then generate a notification in response to determining that the total weight of the processing chamber (including its contents) is within a certain amount of 15 pounds. The certain amount may be a fixed value (e.g., 1 pound or 2 pounds), or the certain amount may be a dynamically determined value (e.g., 5 percent or 10 percent of the weight specified by the user).
The notification could be presented in various ways. In embodiments where the control platform 1102 is implemented as a computer program executing on an electronic device 1104 as shown in
As shown in
In some embodiments, at least some components of the control platform 1102 are hosted locally. That is, part of the control platform 1102 may reside on the electronic device 1104 that is used to access the interfaces 1106 as shown in
In other embodiments, the control platform 1102 is executed entirely by a cloud computing service operated by, for example, Amazon Web Services®, Google Cloud Platform™, or Microsoft Azure®. In such embodiments, the control platform 1102 may reside on a server system 1110 that is comprised of one or more computer servers. These computer servers can include different types of data (e.g., regarding batches of product that have been produced by OMPAs associated with different users), algorithms for implementing the routine described above (e.g., based on knowledge regarding ambient temperatures, humidity, etc.), algorithms for tailoring or training the routine described above (e.g., based on knowledge gained from nearby OMPAs or comparable OMPAs), and other assets (e.g., user credentials). Those skilled in the art will recognize that this information could also be distributed amongst the server system 1110 and one or more other electronic devices. For example, some data that is generated by a given OMPA may be stored on, and processed by, that OMPA or an electronic device that is “paired” with that OMPA. Thus, not all data generated by OMPAs—or even the control platform—may be transmitted to the server system 1110 for security or privacy purposes.
One benefit of having a network-connected OMPA is that it enables connectivity with other electronic devices, and thus integration into related systems.
Assume, for example, that a user purchases and then deploys a OMPA in a home. This OMPA may include a set of instructions (also referred to as the “intelligent time recipe”) that, when executed, indicate how its components are to be controlled. These instructions may involve the execution of heuristics, algorithms, or computer-implemented models. Rather than learn best practices “from scratch,” the OMPA (or a control platform to which it is communicatively connected) may be able to learn from the experiences of other OMPAs. These OMPAs may be located nearby, and therefore may experience comparable ambient conditions such as humidity, temperature, and the like. Alternatively, these OMPAs may be comparable, for example, in terms of amount of actual or expected OMPA input, type of actual or expected OMPA input, number of users (e.g., a single individual versus a family of four individuals), etc. Thus, knowledge may be shared among OMPAs as part of a networked machine learning scheme. Referring again to the above-mentioned example, the OMPA may initiate a connection with a control platform after being deployed in the home. In such a scenario, the control platform may provide another set of instructions that is learned based on knowledge gained by the control platform from analysis of the activities of other OMPAs. Accordingly, the control platform may further develop instruction sets based on machine learning. Learning may be performed continually (e.g., as OMPAs perform activities and generate data), and insights gained through learning may be provided continually or periodically. For instance, the control platform may communicate instructions to a OMPA whenever a new set is available, or the control platform may communicate a new set of instructions to an OMPA only upon receiving input (e.g., from the corresponding user) indicating that the OMPA is not operating as expected.
As another example, assume that a municipality is interested in collecting the products produced by various OMPAs for further processing (e.g., composting). In such a scenario, the municipality may be interested in information such as the weight and water content of product that is available for collection. Each OMPA may not only have the sensors needed to measure these characteristics as discussed above but may also have a communication module that is able to transmit measurements elsewhere. In some embodiments, these OMPA directly transmit the measurements to the municipality (e.g., by uploading to a network-accessible data interface, such as an application programming interface). In other embodiments, these OMPAs indirectly transmit the measurements to the municipality (e.g., by forwarding to respective control platforms, which then transmit the measurements—or analyses of the measurements—onward to the municipality). With these measurements, the municipality may be able to retrieve, transport, and handle the products produced by these OMPAs in a more intelligent manner. For example, the municipality may have a better understanding of when retrieval needs to occur, and how much storage space is needed for the products, if the weight is shared.
Users may also be able to communicate with one another, directly or indirectly, through OMPA. Assume, for example, that a first OMPA has finished processing its OMPA input into a product. Although processing is complete, a corresponding first user may not be ready to offload the product. In such a situation, a second user who is located nearby (e.g., as determined based on information generated by the respective OMPA, information input by the respective users, etc.) may offer to handle the product. For instance, the second user may retrieve the product from the first user and then handle it, add it to her own product, etc. Users may be able to communicate through the interfaces 1106 generated by the control platform 1102, or users may be able to communicate directly through their respective OMPAs.

The network adapter 1212 enables the computing system 1200 to mediate data in a network 1214 with an entity that is external to the computing system 1200 through any communication protocol that is supported by the computing system 1200 and the external entity. The network adapter 1212 can include a network adaptor card, wireless network interface card, router, access point, wireless router, switch, protocol converter, gateway, bridge, hub, digital media receiver, repeater, or any combination thereof.
