My Invention "Kitchen Items Cleaning Device" is related to kitchen items cleaning and disinfecting device using water and UV-light and also to a solution for sterilizing, preserving, and/or the like, a storage area of a storage device using ultraviolet radiation. This invention is an apparatus for sanitizing articles such as envelopes, parcels, or packages sent by mail or courier, and more particularly to an apparatus which uses high energy microwave and ultraviolet radiation, along with a gas to kill contaminants such as bacteria and viruses on the surface or inside of the envelope or package.
Reliable, hygienic storage of sanitary and biological items, such as food, is a major problem. For example, the problem is present throughout the food industry, e.g., manufacturers, retailers, restaurants, and in every household, and is especially significant for food service establishments, in which related issues of food quality control also are significant. In addition to food storage and quality control in fixed locations (e.g., a refrigerator) where access to electricity is readily available, proper food storage and quality control also is important in situations for which access to unlimited electricity and/or a stationary storage device, such as a refrigerator, is not available, such as picnics, camping, mobile food kiosks, hospitality or battlefield meal locations, search and rescue, etc. In addition to food, other stored items also require hygienic storage. For example, medical and chemical equipment, construction wood, etc., also require storage in a biologically safe environment. Since ambient temperature significantly affects bacterial activity, effective control of the ambient temperature is an important tool in ensuring reliable, hygienic storage of various items.
Fresh food products can be processed using ultraviolet light as a germicidal medium to reduce the food-born microbial load. Water has been treated with ultraviolet light to provide safe drinking water for quite some time. Fruit and vegetable products capable of being pumped through a system generally are very suitable for processing by ultraviolet light to reduce the microbial load. Today, most of these products are pasteurized to obtain microbiologically safe and nutritious products. However, pasteurization can change the taste and flavor of such products because of the temperature and processing time. Juices from different sources can be treated by exposure to ultraviolet light at different doses. On the other hand, variables such as exposure time, type of fruit product, juice color and juice composition, among other variables, need to be studied to obtain fruit products with reduced microbial load, increased shelf life and adequate sensory and nutritional characteristics. Reduction of microbial load through ultraviolet light application as a disinfection medium for food products other than liquids also is being studied. Moreover, ultraviolet technology could be a source for pasteurization of liquids, or disinfection of solid foods as an alternative technology, instead of thermal treatment or application of antimicrobial compounds.
The ultraviolet (UV) light is classified into three wavelength ranges: UV-C, from about 200 nanometers (nm) to about 280 nm; UV-B, from about 280 nm to about 315 nm; and UV-A, from about 315 nm to about 400 nm. Generally, ultraviolet light, and in particular, UV-C light is "germicidal," i.e., it deactivates the DNA of bacteria, viruses and other pathogens and thus destroys their ability to multiply and cause disease. This effectively results in sterilization of the microorganisms. Specifically, UV-C light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of these bonds prevents the DNA from being "unzipped" for replication, and the organism is neither able to produce molecules essential for life process, nor is it able to reproduce. In fact, when an organism is unable to produce these essential molecules or is unable to replicate, it dies. UV light with a wavelength of approximately between about 250 to about 280 nm provides the highest germicidal effectiveness. While susceptibility to UV light varies, exposure to UV energy for about 20 to about 34 milliwatt-seconds/cm 2 is adequate to deactivate approximately 99 percent of the pathogens.
Various approaches have sought to use ultraviolet light to disinfect a compartment, such as compartments found in refrigerators. For example, one approach proposes a plurality of small, low current UV lights which utilize the standard circuitry of the refrigerator to power the UV light source. Another approach uses a UV lamp installed in a top portion of the refrigerator and reflective lining throughout the interior to reflect the UV radiation throughout the compartment. Another approach provides a UV system with a single UV source attached to an internal sidewall of a refrigerator to radiate light to the entire compartment, or in the alternative, provide UV exposure to a limited compartment. Still another approach proposes an air cleaner for an internal compartment of a refrigerator, which utilizes a UV filter to reduce pathogens in the re-circulated air. Still another approach provides a refrigerator with UV light irradiation components to eradicate low level light from the storage containers contained therein to promote freshness of foodstuffs.
Machines resembling assembly lines through which food articles and the like pass use several different energy or radiation sources to sanitize the foodstuff, for example, to kill E coli and botulism bacteria in the production plant. Cobalt 60, a radioactive material which emits gamma radiation, kills such bacteria, but the radioactive radiation it emits may expose plant workers to a hazard. Similarly, x-rays and electron beams can effectively kill undesirable organisms without rendering the foodstuff inedible, but they too present environmental hazards, and their cost of installation and power consumption may make them undesirable or impractical for either small scale or mass treatment of mail, packages, and the like. It is therefore an object of the invention to provide a sanitizing apparatus which will effectively kill pathogens, such as bacteria, viruses, spores, mold, and the like on the surface and the interior of packages and envelopes.
The foregoing disadvantages of prior devices can be overcome by the present invention by providing an apparatus for sanitizing a plurality of articles, which comprises a housing enclosing a sanitizing zone, the housing having a seal for preventing leakage of gas or fluid from the sanitizing zone; a pump for introducing an antimicrobial fluid into the sanitizing zone; and a pump for withdrawing the fluid from the sanitizing zone. The device also includes at least one high power microwave source and at least one ultraviolet irradiating source, or a microwave source that also generates ultraviolet radiation. Preferably, the gas is a halogen, such as chlorine, bromine, or iodine, or a gas or fluid containing chlorine or bromine ions, but it can be ozone or another gas which kills bacteria, microbes, viruses, and other pathogens. The fluid can also be sprayed droplets or vaporized sodium hypochlorite, or similar antiseptic agent. The invention also provides a method for killing microbes and pathogens on a plurality of articles, the method comprising: moving articles into a sanitizing zone; introducing an antimicrobial fluid in the presence of ultraviolet and microwave energy; and retaining the articles in the sanitizing zone for a period of time sufficient to kill microbial matter on the articles.

FIG. 1: shows an illustrative ultraviolet radiation system 10 according to an embodiment. In this case, the system 10 includes a monitoring and/or control system 11, which is implemented as a computer system 20 including an analysis program 30, which makes the computer system 20 operable to manage an ultraviolet (UV) radiation source 12 by performing a process described herein. In particular, the analysis program 30 can enable the computer system 20 to operate the UV radiation source 12 to generate and direct ultraviolet radiation within an area and process data corresponding to one or more conditions of the area and/or an item located in the area, which is acquired by a feedback component 14. While a single UV radiation source 12 is shown, it is understood that the area can include any number of UV radiation sources 12, the operation of which the computer system 20 can separately manage using a process described herein.
The during an initial period of operation (e.g., after recent access to the area, addition/removal/reconfiguration of item(s) placed within the area, and/or the like), the computer system 20 can acquire data from the feedback component 14 regarding one or more attributes of the items in the area and/or conditions of the area and generate analysis data 42 for further processing. The analysis data 42 can include information on the color, appearance, and/or the like, of items in the area, the presence of microorganisms on the items or within the area, and/or the like. Furthermore, the analysis data 42 can include information on the presence of ethylene gas within the area. The computer system 20 can use the analysis data 42 to generate calibration data 40 for controlling one or more aspects of the ultraviolet radiation generated by the ultraviolet radiation source(s) 12 using one of a plurality of selectable operating configurations as discussed herein. Furthermore, one or more aspects of the operation of the ultraviolet radiation source 12 can be controlled by a user 6 via an external interface component 26B.
The computer system 20 is shown including a processing component 22 (e.g., one or more processors), a storage component 24 (e.g., a storage hierarchy), an input/output (I/0) component 26A (e.g., one or more I/0 interfaces and/or devices), and a communications pathway 28. In general, the processing component 22 executes program code, such as the analysis program 30, which is at least partially fixed in the storage component 24. While executing program code, the processing component 22 can process data, which can result in reading and/or writing transformed data from/to the storage component 24 and/or the I/O component 26A for further processing.
The pathway 28 provides a communications link between each of the components in the computer system 20. The I/O component 26A and/or the external interface component 26B can comprise one or more human I/O devices, which enable a human user 6 to interact with the computer system 20 and/or one or more communications devices to enable a system user 6 to communicate with the computer system 20 using any type of communications link. To this extent, during execution by the computer system 20, the analysis program 30 can manage a set of interfaces (e.g., graphical user interface(s), application program interface, and/or the like) that enable human and/or system users 6 to interact with the analysis program 30. Furthermore, the analysis program 30 can manage (e.g., store, retrieve, create, manipulate, organize, present, etc.) the data, such as calibration data 40 and analysis data 42, using any solution.
The computer system 20 can comprise one or more general purpose computing articles of manufacture (e.g., computing devices) capable of executing program code, such as the analysis program 30, installed thereon. As used herein, it is understood that "program code" means any collection of instructions, in any language, code or notation, that cause a computing device having an information processing capability to perform a particular function either directly or after any combination of the following: (a) conversion to another language, code or notation; (b) reproduction in a different material form; and/or (c) decompression. To this extent, the analysis program 30 can be embodied as any combination of system software and/or application software.
Furthermore, the analysis program 30 can be implemented using a set of modules 32. In this case, a module 32 can enable the computer system 20 to perform a set of tasks used by the analysis program 30, and can be separately developed and/or implemented apart from other portions of the analysis program 30. When the computer system 20 comprises multiple computing devices, each computing device can have only a portion of the analysis program 30 fixed thereon (e.g., one or more modules 32). However, it is understood that the computer system 20 and the analysis program 30 are only representative of various possible equivalent monitoring and/or control systems 11 that may perform a process described herein. To this extent, in other embodiments, the functionality provided by the computer system 20 and the analysis program 30 can be at least partially implemented by one or more computing devices that include any combination of general and/or specific purpose hardware with or without program code.
The the hardware and program code, if included, can be created using standard engineering and programming techniques, respectively. In another embodiment, the monitoring and/or control system 11 can be implemented without any computing device, e.g., using a closed loop circuit implementing a feedback control loop in which the outputs of one or more sensing devices are used as inputs to control the operation of one or more other devices (e.g., LEDs). Illustrative aspects of the invention are further described in conjunction with the computer system 20. However, it is understood that the functionality described in conjunction therewith can be implemented by any type of monitoring and/or control system 11.
Regardless, when the computer system 20 includes multiple computing devices, the computing devices can communicate over any type of communications link. Furthermore, while performing a process described herein, the computer system 20 can communicate with one or more other computer systems, such as the user 6, using any type of communications link. In either case, the communications link can comprise any combination of various types of wired and/or wireless links; comprise any combination of one or more types of networks; and/or utilize any combination of various types of transmission techniques and protocols. This communications link, which can include a wireless or cable based transmission, can be utilized to transmit information about the state of one or more items and/or zones within the storage area 54.
The system 10 can be implemented within an existing storage device (e.g., a refrigerator) using any solution. For example, one or more ultraviolet radiation sources 12 and one or more devices included in a feedback component 14 can be fixed within various locations in the storage device (e.g., on walls, shelves, etc.) and configured for operation by the computer system 20. The locations of devices in the ultraviolet radiation source(s) 12 and/or the feedback component 14 can be selected to provide comprehensive coverage of the storage area of the storage device and the items located within the storage area. In an embodiment, the computer system 20 can be located outside of the storage area of the storage device.
The ultraviolet radiation source 12 can comprise any combination of one or more ultraviolet radiation emitters. For example, the UV source 12 can include a high intensity ultraviolet lamp (e.g., a high intensity mercury lamp), an ultraviolet light emitting diode (LED), and/or the like. In an embodiment, the UV source 12 includes a set of light emitting diodes manufactured with one or more layers of materials selected from the group-III nitride material system (e.g., AlxlnyGai-x-N, where 0 x, y1, and x+y 1 and/or alloys thereof). Additionally, the UV source 12 can comprise one or more additional components (e.g., a wave guiding structure, a component for relocating and/or redirecting ultraviolet radiation emitter(s), etc.) to direct and/or deliver the emitted radiation to a particular location/area, in a particular direction, in a particular pattern, and/or the like, within the storage area. Illustrative wave guiding structures include, but are not limited to, a plurality of ultraviolet fibers, each of which terminates at an opening, a diffuser, and/or the like. The computer system 12 can independently control each UV source 12.
The system 10 also can include an alarm component 23, which can be operated by the computer system 20 to indicate when ultraviolet radiation is being directed within the storage area. The alarm component 23 can include one or more devices for generating a visual signal, an auditory signal, and/or the like. For example, in the example shown in FIG. 5A, where the storage device 52 includes a refrigeration device, a panel 8 can display a flashing light, text, an image, and/or the like, to indicate that ultraviolet radiation is currently being directed into a corresponding storage area 54. Furthermore, the alarm component 23 can generate a noise, such as a bell, a beep, and/or the like, to indicate that ultraviolet radiation is currently being directed to the storage area 54.
FIG. 2: is a shows a block diagram illustrating use of operating configurations for operating an ultraviolet radiation source 12 according to an embodiment. As illustrated, the computer system 20 can use data corresponding to a selected operating configuration 50A-50C to adjust one or more aspects of the ultraviolet radiation 13 generated by the ultraviolet radiation source(s) 12. In an embodiment, the operating configurations 50A-50C include a sterilization operating configuration 50A, a preservation operating configuration 50B, and a condition monitoring operating configuration 50C. In an embodiment, the sterilization operating configuration 50A is configured to disinfect, sterilize, and/or eradicate the storage area of microorganisms. The sterilization operating configuration 50A also can be configured to perform chemical decontamination using any solution. The preservation operating configuration 50B is configured to prevent dark reactivation and photo reactivation of microorganisms to avoid microorganism growth above acceptable levels, as discussed herein. Additionally, the computer system 20 can operate the ultraviolet radiation source 12 in a condition monitoring operating configuration 50C, during which a relatively low level of ultraviolet radiation can be generated in order to detect bacteria and/or the like, which may fluoresce in the ultraviolet light.
The computer system 20 is configured to control and adjust a direction, an intensity, a pattern, and/or a spectral power (e.g., wavelength) of the UV sources 12 to correspond to a particular operating configuration 50A-50C. The computer system 20 can control and adjust each property of the UV source 12 independently. For example, the computer system 20 can adjust the intensity, the time duration, and/or time scheduling (e.g., pattern) of the UV source 12 for a given wavelength. Each operating configuration 50A C can designate a unique combination of: a target ultraviolet wavelength, a target intensity level, a target pattern for the ultraviolet radiation (e.g., time scheduling, including duration (e.g., exposure/illumination time), duty cycle, time between exposures/illuminations, and/or the like), a target spectral power, and/or the like, in order to meet a unique set of goals corresponding to each operating configuration 50A C.
For the sterilization operating configuration 50A, a target wavelength range can be approximately 250 nanometers to approximately 310 nanometers. Referring to FIG. 3A, a graph illustrating the intensity level 15A for the ultraviolet radiation over time (both in arbitrary units) of the sterilization operating configuration 50A is shown. The intensity level 15A can be a high intensity short burst of ultraviolet radiation. In an embodiment, the intensity level and time are selected to provide a dose sufficient to achieve a 6 log inactivation of bacteria. For example, such a dose can range between approximately 10 and approximately 100 milliJoules/cm 2
. The intensity of the ultraviolet radiation can be selected to provide an overall exposure integrated over the period of exposure to provide such a dose. An illustrative period of exposure comprises a few microseconds, Regardless, it is understood that this level of inactivation is only illustrative and other levels of inactivation can be selected. For the preservation operating configuration 50B, a target wavelength range can be approximately 190 nanometers to approximately 285 nanometers. Referring to FIG. 3B, a graph illustrating the intensity level for the ultraviolet radiation over time (both in arbitrary units) of the preservation operating configuration 50B is shown. The intensity level can be a low intensity ultraviolet radiation that can be either continuous 15B or periodic 15C. The intensity level also can be aperiodic at a predetermined schedule. For the periodic/aperiodic intensity level 15C, the intensity level/duration and period (e.g., time between peaks) can be chosen to be commensurable with the preservation operating configuration 50B, such that microorganisms present in the storage area are prevented from growing upon a predetermined level. Regardless, it is understood that a selected intensity and duration for either operating condition can be adjusted based on one or more of: a target microorganism, a desired level of suppression/inactivation, a wavelength of the ultraviolet radiation, and/or the like.
FIG. 4: shows an illustrative system including an ultraviolet radiation system 10 according to an embodiment. The computer system 20 is configured to control the UV source 12 to direct ultraviolet radiation 13 into a storage area 54 of a storage device 52, within which a set of items 56 are located. The feedback component 14 is configured to acquire data used to monitor a set of current conditions of the storage area 54 and/or the items 56 over a period of time. As illustrated, the feedback component 14 can include a plurality of sensing devices 16, each of which can acquire data used by the computer system 20 to monitor the set of current conditions.
It is understood that the set of current conditions in the storage area 54 can include one or more attributes corresponding to a set of biological activity dynamics present within the storage area. The set of biological activity dynamics can include, for example, a presence of biological activity (e.g., exponential bacterial growth), a location of the biological activity, a type of biological activity (e.g., type of organism), a concentration of the biological activity, an estimated amount of time an organism has been in a growth phase (e.g., exponential growth and/or stationary), and/or the like. The set of biological activity dynamics can include information on the variation of the biological activity over time, such as a growth rate, a rate with which an area including the biological activity is spreading, and/or the like. In an embodiment, the set of biological activity dynamics are related to various attributes of bacteria and/or virus activity within an area, including, for example, the presence of detectable bacteria and/or virus activity, measured bacteria and/or virus population/concentration time dynamics, growth phase, and/or the like.
The sensing devices 16 include at least one of a visual camera or a chemical sensor. The visual camera can acquire data (e.g., visual, electronic, and/or the like) used to monitor the storage area 54 and/or one or more of the items 56 located therein, while the chemical sensor can acquire data (e.g., chemical, electronic, and/or the like) used to monitor the storage area 54 and/or one or more of the items 56 located therein. The set of current conditions of the storage area 54 and/or items 56 can include the color or visual appearance of the items 56, the presence of microorganisms within the storage area 54, and/or the like. For example, when the computer system 20 is operating the UV radiation source 12, a visual camera and/or a chemical sensor monitoring the storage area 54 may be operated to detect the presence of microorganisms. In a specific embodiment, the visual camera comprises a fluorescent optical camera that can detect bacteria 56 and/or viruses 58 that become fluorescent under ultraviolet radiation. However, it is understood that a visual camera and a chemical sensor are only illustrative of various types of sensors that can be implemented.
For example, the sensing devices 16 can include one or more mechanical sensors (including piezoelectric sensors, various membranes, cantilevers, a micro electromechanical sensor or MEMS, a nanomechanical sensor, and/or the like), which can be configured to acquire any of various types of data regarding the storage area 54 and/or items 56 located therein. In another embodiment, the sensing devices 16 can include a UV detector that is configured to detect ultraviolet radiation within the storage area 54. The absorption of ultraviolet radiation within storage area 54 can indicate the presence of bacteria 56 and/or virus 58. The UV detector can be a solid state ultraviolet radiation detector manufactured with one or more layers of materials selected from the group-III nitride material system (e.g., AlxInyGai-x-N, where OX, Y1, and X+Y 1 and/or alloys thereof). For example, the UV detector can comprise any type of ultraviolet sensing device, such as an ultraviolet-sensitive photodetector (e.g., an ultraviolet photodiode). In an embodiment, the UV detector can be selected based on its sensitivity to a particular, narrow band of ultraviolet light, which can be selected using any solution. Additionally, the UV detector can comprise one or more additional components (e.g., a wave guiding structure, filter, system for moving and/or redirecting ultraviolet detector(s), etc.) to detect ultraviolet radiation in a particular location/direction, and make the UV detector sensitive to a particular range of wavelengths, and/or the like.
The feedback component 14 also can include one or more additional devices. For example, the feedback component 14 is shown including a logic unit 17. In an embodiment, the logic unit 17 receives data from a set of sensing devices 16 and provides data corresponding to the set of conditions of the storage area 54 and/or items 56 located in the storage area 54 for processing by the computer system 20. In a more particular embodiment, the computer system 20 can provide information corresponding to the currently selected operating configuration 50 for use by the feedback component 14. For example, the logic unit 17 can adjust the operation of one or more of the sensing devices 16, operate a unique subset of the sensing devices 16, and/or the like, according to the currently selected operating configuration 50. In response to data received from the feedback component 14, the computer system 20 can automatically adjust and control one or more aspects of the ultraviolet radiation 13 generated by the ultraviolet radiation source 12 according to the currently selected operating configuration 50.
The system 10 can include a single type of UV source 12 that is capable of operating in both operating configurations SOA, SOB. For example, the system 10 can include a type of
UV source 12 that can operate in the high intensity level for the sterilization operating configuration 50A in order to sterilize microorganisms, such as bacteria, protozoa, and/or the like, and also operate in the low intensity level for the preservation operating configuration 50B in order to prevent the microorganisms, such as bacteria, protozoa, and/or the like, from growing and reproducing. The computer system 20 can be capable of adjusting the relative intensities, time durations, and/or time schedules of the UV sources 12 to correspond to these operating configurations 50.
The system 10 can include at least two types of UV sources 12. Referring now to FIG. 9, a perspective view of an illustrative storage device 152 according to an embodiment is shown. The storage device 152 includes a first set of UV sources 12A and a second set of UV sources 12B. The first set of UV sources 12A can be configured to operate in a first operating configuration, such as the sterilization operating configuration 50A, while the second set of UV sources 12B can be configured to operate in a second operating configuration, such as the preservation operating configuration 50B, or vice versa.
The storage device 152 can include a plurality of sub-compartments that are individually monitored by the feedback component 14 (FIG. 1). The ultraviolet radiation sources 12 in each sub-compartment can be individually controlled by the computer system 20. For example, a shelf 72 can be partitioned into a first sub-compartment 76 and a second sub compartment 78, which are separated by a divider 80. The computer system 20 can control the UV source 12A to have a first intensity and a first wavelength, and control the UV source 12B to have a second intensity and a second wavelength. For example, the UV source 12A can include a full intensity, while the UV source 12B includes a zero intensity. Conversely, the UV source 12A can include a zero intensity, while the UV source 12B includes a full intensity. Furthermore, the computer system 20 can independently tune the relative intensities of each UV source 12A, 12B, and either UV source 12A, 12B can have any intensity between zero and full.
As described herein, embodiments can be implemented as part of any of various types of storage systems. FIGS. 5A-5C, 6A-6F, 7A-7B, and 8A-8E show illustrative storage devices for use with an ultraviolet radiation system 10 (FIG. 1) according to embodiments. For example, the storage device can be a refrigerator and/or freezer (FIG. 5A) for storing a plurality of food items. In this embodiment, the computer system 20 can be configured to turn off UV source 12 when a door is open, and automatically turn on UV source 12 when the door is closed. Alternatively, the system 10 can be implemented in a cooler (FIG. 5B). The system 10 can be implemented in a pantry (FIG. 5C, e.g., a shelf in the pantry), and/or the like. The system 10 can be implemented in a food storage container (FIG. 6A), a backpack (FIG. 6B), a grocery bag (FIG. 6C), or a plastic baggie (FIG. 6D). In an alternative embodiment, system 10 may be utilized with an electronic toothbrush (FIG. 6E) or with a mobile touch screen phone (FIG. 6F).
The system 10 can also be implemented in a dishwasher (FIG. 7A), or a sushi bar (FIG. 7B). Further, system 10 can be implemented in storage device (FIG. 8A), a vacuum cleaner (FIG. 8B), a floor cleaning robot (FIG. 8C), a floor cleaning machine (FIG. 8D), or a pc tablet case (FIG. 8E). In each case, an embodiment of the system 10 can be implemented in conjunction therewith using any solution. To this extent, it is understood that embodiments of the system 10 can vary significantly in the number of devices, the size of the devices, the power requirements for the system, and/or the like. Regardless, it is understood that these are only exemplary storage devices and that the system 10 may be applicable to other storage devices not specifically mentioned herein.
Returning to FIG. 3: it is understood that the system 10 may include a power component 19 that is implemented separately from the storage device 52 to supply power to one or more of the various components of system 10, such as ultraviolet radiation sources 12, feedback component 14, computer system 20, and/or the like. For example, the storage device 52 may comprise a cooler or the like, which does not include or otherwise require any power source. Furthermore, the storage device 52 may comprise a power source that is insufficient to operate the various devices of system 10 in addition to maintaining one or more aspects of the environment within the storage area 54 for a desired period of time. Regardless, the power component 19 can be utilized to operate system 10. The power component 19 can comprise any source of power including, but not limited to, the power grid, a battery set, an automotive charger, a solar cell, and/or the like.
The computer system 20 can implement multiple modes of operation depending on the source of power. In particular, when a power component 19 of limited capacity is being utilized, one or more functions of system 10 can be disabled and/or reduced to lengthen an operating time for system 10. For example, use of ultraviolet radiation source 12 to prolong the life of items within the storage area 54 or disinfect the storage area 54 by generating a higher intensity of ultraviolet radiation can be disabled.
An environment within the storage area 54 can be controlled by an environmental control component 18. In an illustrative implementation, the environmental control component 18 can comprise a temperature control module, a humidity control module, and/or a convection control module. During normal operation of the environmental control component 18, a user 6 (FIG. 1) (e.g., using external interface component 26B) can select a desired temperature, humidity, and/or the like, to maintain within storage area 54. The environmental control component 18 can subsequently operate one or more cooling/heating components of temperature control module to maintain the desired temperature, operate one or more humidifying/dehumidifying components of humidity control module to maintain the desired humidity, operate one or more air or fluid convection components (e.g., fan, pump, vent, valve, etc.) of convection control module to assist in maintaining a relatively even temperature/humidity within storage area 54, and/or the like. Alternatively, local temperature control within storage area 54 can be maintained by cool air recirculation that is controlled by the environmental control component 18.
The computer system 20 can be configured to adjust one or more operating parameters of the environmental control component 18 based on a set of current conditions in the storage area 54 and/or an operating configuration 50 of the UV radiation source 12. For example, the computer system 20 can adjust one or more of: a temperature, a humidity, a gas convection, and/or a fluid convection of the storage area 54 in response to a set of biological activity dynamics and according to a currently selected operating configuration.
To this extent, each operating configuration can further define a set of target environmental conditions for use during the UV illumination. Such environmental conditions can include a target temperature, a target humidity, additional illumination by non-ultraviolet sources (e.g., visible, infrared), air circulation, and/or the like, Furthermore, one or more of the environmental conditions can change over time during implementation of the operating configuration. In an illustrative embodiment, the computer system 20 can operate the environmental control component 18 to circulate air into a chamber 60.
The chamber 60 may be a source of ethylene or other gas and the computer system 20 can control chamber 60 to calibrate exposure of stored articles to such gas. The storage area 52 can also include catalysts 62 for enhancing the suppression of the biological activity, such as, titanium dioxide. Furthermore, the set of current conditions in the storage area 54 can include an operating condition of one or more components of the system 10, such as the ultraviolet radiation source(s) 12. Information regarding the operating condition can be used to, for example, notify a user 6 of a problem using the alarm component 23, alter one or more aspects of an operating configuration, and/or the like. Additionally, the set of current conditions in the storage area 54 can include data corresponding to a dose of ultraviolet radiation delivered by an ultraviolet radiation source 12 during a predetermined time period. In this case, the computer system 20 can dynamically determine when to turn off the ultraviolet radiation source 12.
As described herein, aspects of the invention can be implemented to treat (e.g., preserve, disinfect, and/or the like) various types of food stored in various types of environments. A typical environment can comprise a refrigerated environment, in which food is frequently stored to extend the shelf life of the food. However, embodiments can be implemented in other non-refrigerated environments, in which food is stored for a period of time, e.g., to ripen, prior to being used, and/or the like. Furthermore, an embodiment can be implemented in conjunction with a freezer, in which the temperature is maintained well below the freezing point of water.
To this extent, the types of food items to which aspects of the invention can be implemented can include various types of food as described herein. As described herein, the foods can include various types of fruits and vegetables. However, the foods also can include frozen consumables, such as ice cubes, ice cream, and/or the like. Furthermore, the foods can include liquids, grains, cereals, and/or the like. Additionally, as described herein, embodiments can be implemented to treat non-food items stored in any type of environment. Such non-food items can include, for example, frozen/liquid chemicals, sand, wood, and/or the like. Regardless, it is understood that a treated item can be ultraviolet transparent (e.g., semi-transparent), ultraviolet absorbing, and/or ultraviolet reflective.
While shown and described herein as a method and system for managing a storage area, it is understood that aspects of the invention further provide various alternative embodiments. For example, in one embodiment, the invention provides a computer program fixed in at least one computer-readable medium, which when executed, enables a computer system to manage the storage area using a process described herein. To this extent, the computer-readable medium includes program code, such as the analysis program 30 (FIG. 1), which enables a computer system to implement some or all of a process described herein. It is understood that the term "computer-readable medium" comprises one or more of any type of tangible medium of expression, now known or later developed, from which a copy of the program code can be perceived, reproduced, or otherwise communicated by a computing device. For example, the computer-readable medium can comprise: one or more portable storage articles of manufacture; one or more memory/storage components of a computing device; paper; and/or the like.
The invention provides a method of providing a copy of program code, such as the analysis program 30 (FIG. 1), which enables a computer system to implement some or all of a process described herein. In this case, a computer system can process a copy of the program code to generate and transmit, for reception at a second, distinct location, a set of data signals that has one or more of its characteristics set and/or changed in such a manner as to encode a copy of the program code in the set of data signals. Similarly, an embodiment of the invention provides a method of acquiring a copy of the program code, which includes a computer system receiving the set of data signals described herein, and translating the set of data signals into a copy of the computer program fixed in at least one computer-readable medium. In either case, the set of data signals can be transmitted/received using any type of communications link.
The invention provides a method of generating a system for managing the storage area. In this case, the generating can include configuring a computer system, such as the computer system 20 (FIG. 1), to implement a method of managing the storage area as described herein. The configuring can include obtaining (e.g., creating, maintaining, purchasing, modifying, using, making available, etc.) one or more hardware components, with or without one or more software modules, and setting up the components and/or modules to implement a process described herein. To this extent, the configuring can include deploying one or more components to the computer system, which can comprise one or more of: (1) installing program code on a computing device; (2) adding one or more computing and/or I/0 devices to the computer system; (3) incorporating and/or modifying the computer system to enable it to perform a process described herein; and/or the like.
FIG. 10: The sanitizing device 10 includes conveyor belt 12 including a continuous belt 14 driven by rollers 16. Some of the rollers 16 are rotated by gears 18 driven by an electric motor 20. As in a conventional conveyor belt, the belt 14 carries along a plurality of articles 22 such as envelopes, packages, containers and the like. The sanitizing apparatus 10 of the present invention can therefore be used in a post office or other government facility, or in the mailroom of an office, bank, hotel, hospital, factory, or other business institution. Since it includes a conveyor 14, it can be installed as a module in a mail sorting or handling line.
The sanitizing assembly 10 of the present invention uses a plurality of ultraviolet and microwave radiation sources 24 to irradiate the sanitizing zone 19 through which packages or envelopes 22 pass through on the conveyor belt 14. Optionally, an x-ray detection system (not shown) can be used. The optional x-ray system can visualize the contents of the package or envelope to determine whether it contains any explosive or other hazardous device or substance. A metal sensing device 17 at the front of the conveyor such as a magnetometer or capacitance sensor recognizes packages with metallic packaging material, and an arm (not shown) shunts them aside to avoid exposure of metal to microwave radiation.
Additionally, the apparatus 10 includes a series of spigots 26 which introduce a fluid, such as a halogen gas (e.g., chlorine, iodine or bromine), ozone, a peroxide containing gas, chlorine dioxide gas, or a chlorine or chlorine and oxygen containing compound, such as calcium or sodium chloride or calcium or sodium hypochlorite. Other sources of chlorine ions or chlorine and oxygen containing ions may also be used, as may a carbohydrate containing substrance or fluid, such as soy bean derivative. Fluid containing chlorine atoms, such as aqueous sodium hypochlorite (common household bleach) can be vaporized or sprayed into the chamber 19 as a mist of droplets. In such a case, the fluid will include chlorine and oxygen containing atoms, molecules or ions which will kill bacteria, viruses, or other microbial contaminants on the surface of the package 12.
Ultraviolet and microwave radiation would ionize or energize the gas or fluid so that it can react with and destroy biological material. The microwave and ultraviolet radiation by itself would not necessarily heat or irradiate the package sufficiently to kill bacteria or other contaminants, but would help the chlorine, ozone, peroxide or other gas to work more effectively.
Provision can be made to treat both sides of an envelope simultaneously, for example, by providing a mesh conveyor belt or a mechanism (not shown) to flip the envelopes over to complete treatment of a second side. In either case, the article 22 is held for a time sufficient to allow the energized ions, atoms, or molecules to kill the microbes on the surface of the article. U.S. Pat. Nos. 3,817,703 and 5,364,645 both address using various forms of electromagnetic radiation to kill pathogens and microorganisms, and set forth suggested time and energy levels which may be effective in the present apparatus and method. The contents of those patents are incorporated by reference herein.
In a second embodiment, shown schematically in FIG. 12 the article sanitizer 10 can be in the form of a module 11 to add to an existing conveyor belt C used in a postal or sorting facility. Like the previous embodiment, module 11 could include one or more means for introducing an antimicrobial fluid into a sanitizing zone 19 defined by the housing H. The module 11 also includes one or more ultraviolet and microwave radiation sources which may be separate or included in a single unit, as shown in FIG. 12. The second embodiment, like the first, includes a pump 21 for removing antimicrobial fluid from the sanitizing zone or chamber 19. The chamber 19, in any embodiment, should preferably include a series of baffles and gaskets to prevent the antimicrobial gas or other fluid, as well as the radiation, from escaping from the chamber 19.
FIG. 13: the sanitizing apparatus 10 of the present invention may be a module 11 which, in lieu of a conveyor 19, a housing 19 which rests on a table or similar support (not shown). The housing 19 contains the articles 22 which undergo sanitation in an enclosed space S. The space S has walls which allow an operator to insert articles 22, and then close the housing 19 to prevent leakage of antimicrobial fluid and radiation from the housing 19. The apparatus 10 also includes a pump 26 for introducing the fluid into the chamber or space and a pump 21 for removing the fluid and filtering solid matter there from.
The invention can also advantageously employ a perforating mechanism 28 to make tiny holes in the envelope or other package to allow the gas to penetrate the interior of the parcel 22, killing any pathogens contained therein. In the embodiment shown in FIG. 10, the microperforating apparatus 28 is a series of pins mounted on an arm which raises and lowers through a reciprocal motion driven by a motor-cam combination 25. The arm raises and lowers as directed by an electric eye or other detector, which would lift the arm sufficiently to allow a package to pass underneath. It can be lowered so that the tines on the arm perforate the package wrapper slightly without harming the contents. The pinpricks in the package would allow the chlorine or other fluid to enter the interior of the package in order to destroy anthrax or other biohazard, for example, or to allow the spores or microbes to exit the package where they will be destroyed by the antimicrobial fluid. Alternatively, a series of rollers studded with pins or teeth can be used to provide the perforations (not shown). The rollers should move up and down to adjust for different package sizes, but should have a spring or other opposing force mechanism pressing them downward toward the package 22 so that they lightly perforate the cover layers of the package.
A laser 54, such as an excimer laser (see FIG. 11) can provide also light energy to kill microbes and other pathogens. Examples of methods using laser and ultraviolet radiation to disinfect foods may be found in U.S. Pat. No. 5,364,645 (Lagunas-Solar), and U.S. Pat. No. 3,817,703 (Atwood), referenced above. Optionally, an x-ray or other radioactive source can be added, to be used in combination with the high power microwave and UV energy sources incorporated into the present invention.
The apparatus 10 also includes a feedback control system 56, whose operation may be understood with reference to FIG. 11. The 56 system includes a controller 40 to control the amount of energy and gasses released during the operation of the system. Controller 40 includes preprogrammed ROM to control the motor 20 which drives the conveyor belt 14, either incrementally, or linearly.
Controller 40 also controls one or more solenoid or similar type gas or fluid valves 42 through a feedback loop so that the proper disinfecting concentration of gas (for example, ozone, peroxide, chloride, or chlorine) is fed from the gas source 44 into the treatment chamber 19 (FIG. 10) of the apparatus 10. The system 10 is activated by an on/off switch 46 which activates the motor 48 driving the conveyor 14. The controller 40 also switches and controls the microwave radiation source 50, the ultraviolet light source 52, and the optional laser light source 54. The controller 40 either includes, or works in tandem with a feedback control system 56 to regulate the flow of gas, and the intensity of light or energy in the treatment chamber 19. The system 10 preferably includes a gas evacuation and recirculation system 58 including a filter for particulate matter, so that gas used in the treatment apparatus 10 can be reclaimed and recycled or reused.
Controller 40 can also be any suitable type of controller circuit and, for example, can consist of a microprocessor controller. Various types of controllers suitable for use in a device such as the present invention are known in the art. Accordingly, controller 40 will not be described in detail. Briefly, however, controller 40 includes ROM for storing one or more operating programs. Controller 40 can also include RAM that can be programmed by the user through use of an alphanumeric control pad (not shown). Of course, controller 40 can also include various other types of memories and/or peripherals or peripheral interfaces as desired. Controller 40 can also be preprogrammed or can be programmed by the user to automatically run in cycles.
The UV light source may be a monochromatic beam of pulsed ultraviolet or ultraviolet laser radiation having a wavelength of about 240-280 nm. Any type of ultraviolet source producing enough energy to kill pathogens, including Hg lamps emitting 20 nm UV radiation, or low intensity (0.10-10 W/m 2 ) continuous wave polychromatic (broad band) UV radiation can be used. Also desirable would be low intensity (0.10 to 10 W/m 2
) continuous wave polychromatic (broad band) UV radiation (4.88 eV). Pulsed (20 nsec) ultraviolet laser radiation of 193 nm (6.42 eV) may also be used under certain conditions.
FIGS. 10 and 11, the conveyor belt 14 moves when the on/off switch 46 is turned "on". The high intensity UV light source 52 and microwave radiation source 50 irradiate the parcels, packages or envelopes 22 on the conveyor belt 14. The controller 40 opens the solenoid or other control on the gas or fluid control valve 42, allowing gas or fluid to enter from its source or container, such as a gas tank 44, to enter the chamber 19. The high intensity UV and microwave radiation ionizes the gas inside the chamber 19, which in turn kills microbes, such as anthrax or other harmful bacteria or viruses. The contaminated gas is removed by the pump 21, which connects to a filter 23 to remove harmful bacteria and other particulate matter. It may also cleanse the gas so that some or all may be reused.
