For example a CSE may comprises electrical contacts configured to open and / or close a first set of electrical circuits upon installation of the CSE in a rack and open and / or close a second set of electrical circuits upon removal of the CSE from the rack.

[0029] According to an embodiment, an identifier may comprise one or more suitable bar codes. A barcode may be an optical machine-readable representation of data relating to an object to which it is attached. A bar code can be a suitable 1D, 2D or 3D bar code. Bar codes can be read, decoded and / or interpreted by a suitable device (e.g., scanner, imager (e.g., a camera), cell phone) and / or non-transitory computer-readable storage medium (e.g., a non-transitory computer-readable storage medium with an executable program stored thereon, wherein the program instructs a microprocessor to read, decode and / or interpret a bar code).

According to an embodiment, a serial number is unique, or comprises a portion that is unique to a particular system (e.g., a cage rack system) or database.

[0031] Radio-frequency identity (or identification), RFID, is a technology that uses tiny computer chips to track items at a distance. Radio-frequency identification (RFID) is the use of an object (typically a RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader. Radio-frequency identification involves interrogators (or readers), and tags (or labels). RFID tags may contain two parts. One part may be an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions. The second may be an antenna for receiving and transmitting the signal. Generally, there are three types of RFID tags: active RFID tags, which contain a battery and can transmit signals autonomously, passive RFID tags, which have no battery and require an external source to provoke signal transmission, and battery-assisted passive (BAP) RFID tags, which require an external source to be activated and has greater signal range.

[0032] Reflective identifiers may be any type of identifier capable of casting back particles (such as, for example, light, heat, sound, electromagnetic radiation, etc.). Such identifiers may reflect or absorb light (e.g., infrared light), images, or sound waves, for example. Non-reflective identifiers may be any type of identifier not capable of casting back particles.

[0033] Generally, electromagnetic radiation emitted or absorbed by an object is characteristic of the object's electromagnetic spectrum, which electromagnetic spectrum often can be detected.

[0034] Electromagnetic radiation often comprises features such as electromagnetic frequencies and / or electromagnetic wavelengths and an electromagnetic spectrum sometimes comprises substantially all readily detectable electromagnetic radiation. Transparency and / or opaqueness to one or more electromagnetic features can be determined or predetermined by the use of various detectable materials and detectors (e.g., readers). Detectable materials sometimes are part of, included in or layered on materials utilized to generate cage components described herein. In some embodiments, a cage component may be transparent to some wavelengths, but not all electromagnetic wavelengths (e.g., opaque to some wavelengths). According to an embodiment, one or more cage components may be transparent to one or more types of electromagnetic radiation chosen from radio waves, micro wavelengths, infrared wavelengths, visible wavelengths, ultraviolet wavelengths, soft x-rays, the like or combinations of the foregoing. According to an embodiment, one or more cage components may be opaque to one or more types of electromagnetic radiation chosen from radio waves, micro wavelengths, infrared wavelengths, visible wavelengths, ultraviolet wavelengths, soft x-rays, the like or combinations of the foregoing. According to an embodiment, one or more identifiers are transparent or opaque to one or more detection means (e.g., electromagnetic radiation). The term "opaque" with regard to electromagnetic radiation refers to a cage component and / or identifier allowing transmission of 5% or less of an electromagnetic feature.

[0035] Magnetic identifiers, magnetic tags / strips, magnetic ink characters, and / or smart cards may be any type of identifier having properties of a magnet. An example of a system employing magnetic materials is in WO 93 / 14474, which describes a system that generates an electromagnetic field, to which individual transponder units receive, store, and transmit the identification data, which is then received by a receiver. Another example of a system employing magnetic materials is in U.S. Patent No. 4,075,618, which describes an antipilferage magnetic tag detected in an interrogation zone producing an alternating magnetic field by high-order harmonics produced by the presence of the tag. The tag has an asymmetrically shaped piece of low-coercive force ferromagnetic material, including a center section and flux concentrator sections at opposite ends of this section. Another example of a system employing magnetic materials is in U.S. Patent No. 6,144,300, which discloses a magnetic analogue of an optical bar code reader system. Soft magnetic elements are arranged in a linear array and read by mechanically scanning a coil along the array, the coil generating a magnetic null enabling the elements of the array to respond to the applied field. The spatial arrangement of the elements in the linear array defines a code similar to a bar code.

[0036] Symbolic codes or identifiers may be any type of symbol that conveys identity or recognition of any type. A symbol may be something used for or regarded as representing something else; a material object representing something, often something immaterial; emblem, token, or sign. A symbol may be a letter, figure, or other character or mark or a combination of letters or the like used to designate something: the algebraic symbol x or the chemical symbol Au for gold, for example. A symbol also may be a word, phrase, image, or the like having a complex of associated meanings and perceived as having inherent value separable from that which is symbolized, as being part of that which is symbolized, and as performing its normal function of standing for or representing that which is symbolized: usually conceived as deriving its meaning chiefly from the structure in which it appears, and generally distinguished from a sign. A symbol may be commonly known such as a smiley face, or be obscure, non-recognizable, and novel, for example.

[0037] According to an embodiment, chemical identifiers of any type may be used in conjunction with any type of detector to signal the presence of a chemical. The chemical identifier may be triggered by an auto-catalytic chemical reaction, for example by the presence of moisture, by the presence of heat and / or pressure, or by the presence of water and / or another chemical such as ammonium, for example. Chemical identifiers also may be called discoloring polymers, where there is a chemical change within polymers used for identification.

[0038] According to an embodiment, an optical identifier of any type may be used. An optical identifier may comprise an optical substrate or be encoded with optical identification elements, optical character recognition, optical mark recognition, capable of having many optically readable codes. The optical substrate or element may be made of a glass material, such as silica or other glasses, or may be made of plastic or polymer, or any other material capable of having a diffraction grating disposed therein.

[0039] Fluorescence identifiers of any type may be used. Fluorescence identifiers may comprise the emission of radiation or of visible light or luminescence, during exposure to external radiation such as light or x-rays, or other sources of optical emissions, such as an optical reader, for example.

[0040] According to an embodiment, holographic identifiers also may be used, or any type of two, three, or four dimensional image reproduced from a pattern of interference or produced by a split coherent beam of radiation, as from a laser. A holograph may be an image produced by a hologram, which is a negative produced by exposing a high-resolution photographic plate, without camera or lens, near a subject illuminated by monochromatic, coherent radiation, as from a laser when it is placed in a beam of coherent light a true three-dimensional image of the subject is formed.Location of Identifiers

[0041] According to the invention, an identifier is located on an exterior component or portion of the rack. According to an embodiment, one or more identifiers 3 may be located at a suitable location on a CSE or a portion thereof. According to an embodiment, a CSE may comprise an identifier 3 on the front, back, side, top, bottom, proximal portion, distal portion, and / or corner of a CSE or a portion thereof. According to an example, any suitable part or portion of a CSE may comprise an identifier, non-limiting examples of which include a sampling element 250, a retaining arm 200, a shaft of a retaining arm 215, a gasket 150, a housing 100 (e.g., a housing inner surface 105, outer surface 110, hub 141, housing rim 145), a washer 50, a fastener 12, a plug 10 (e.g., a plug grip (e.g., 11 , 11'), grip flange 13, flange rim 16, flange mating surface 18, plug cylinder 17, grip shaft 14, a connector, the like, portions thereof, or combinations thereof. According to an embodiment, a CSE, or a portion thereof comprises one or more identifiers (e.g., see call out number 3 in FIGS. 1 A, 1 B, 1 C and 1 E, 2B, 4A, 5A and 5B, 8A and 8B, 9C and 10). According to an embodiment, a CSE, or a portion thereof, may comprise two or more distinct identifiers and / or two or more identifiers that are substantially the same. According to an embodiment, one or more CSE portions may have a first identifier and a second identifier. For example a plug, housing, sampling element and / or retaining arm may comprise the same identifiers or different identifiers.

[0042] Identifiers on a CSE, or a portion thereof, may be located near another identifier, adjacent to another identifier, overlapping another identifier, on top of another identifier, or in any location where data from the identifier may be captured, accessed, imaged, detected, or interpreted by a reader. One or more identifiers may be arranged in-line with one or more other identifier located on the same or on different parts of a CSE. The term "in-line" as used herein pertains to a linked sequence of placement, such as, sequentially within a line or one identifier behind another identifier thereby forming a straight line.

[0043] According to an embodiment, one or more identifiers are configured so they do not overlap with one another. In alternative embodiments, one or more identifiers are configured so two or more identifiers overlap. In embodiments having overlapping identifiers, the identifiers may be offset from each other thereby generating regions of non-overlapping identifiers and regions of overlapping identifiers. According to an embodiment, overlapping identifiers are detected by the same detector, and in certain embodiments, overlapping identifiers are detected by different detectors. In certain embodiments, each identifier in an overlapping identifier configuration is detected by a different detector. In certain embodiments, a CSE has 2 or more, 3 or more, 4 or more, or more than 5 independently detectable identifiers, and in certain embodiments, a subset or all of the independently detectable identifiers can be detected in various combinations. In embodiments having two or more identifiers (e.g., overlapping or non- overlapping), portions or all of the identifiers may be redundant.

[0044] The location of an identifier on a CSE, or a portion thereof, may be visible or invisible to a user. The location of an identifier is often a location that is visible, detectable or within a line of detection of a reader (e.g., an optical reader). According to an embodiment, one or more identifiers are located within the line of detection of an identifier. The location of an identifier on a CSE, or a portion thereof, and / or the location of a CSE comprising an identifier may be determined according to the location of a reader configured to read the identifier.Readers

[0045] According to the invention, a rack comprises one or more readers. According to the invention, a reader is configured to detect a suitable identifier and / or a CSE. According to the invention, a reader is configured to detect and / or receive CSE identifying information. The term "configured to detect" as used herein in the context of a reader, may refer to the placement (e.g., sometimes a temporary placement, in the case of a hand held reader) of a reader relative to an identifier so that the identifier and reader are in a position, orientation and / or proximity that allows effective detection and / or processing of an identifier by a reader. The term "configured to detect" as used in the context of a reader, can also refer to a correct pairing of a reader with a type of identifier to which the reader is intended to detect. For example, a reader is often configured with a suitable complement of parts (e.g., an imager, a sensor, microprocessor, lens, and the like) that allows detection of a specific type of identifier (e.g., a bar code).

[0046] According to the invention, a reader is coupled to one or more rack components. According to an embodiment, a reader can be located on or in any of a plenum, a support member, a CSE, a cage, a shelf, a wall, duct, controller, computer, caster, trolley system, blower, communication medium, wires, a wiring harness and the like. According to an embodiment, a reader may be attached to a rack component directly or indirectly (e.g., by a bracket or wire). According to an embodiment, a reader may be a handheld device and may be placed at any suitable location on a rack.

[0047] According to the invention, a reader is configured to detect an identifier. According to an embodiment, a reader is paired with and / or positioned to detect one or more specific identifiers. According to an embodiment, a reader is an apparatus or machine configured to detect and / or read one or more specific identifier types (e.g., an image, a bar code, an RFID). According to an embodiment, a reader can be a suitable optical reader, electrical reader and / or a mechanical reader. According to an embodiment, a reader is a suitable device comprising an image sensor and a microprocessor (e.g., a mobile phone, cell phone, smart phone, or a portion thereof, a pad (e.g., an iPad), a tablet, computer, laptop computer, digital camera, the like or combinations thereof). Non- limiting examples of a reader include, pen type readers, a scanner (e.g., a laser scanner), an omni-directional scanner, RFID reader, camera reader (e.g., digital single-lens reflex cameras, CCD readers, CMOS readers) and the like, some of which are described in detail herein.

[0048] According to an embodiment, pen type readers can comprise a light source and a photodiode placed next to each other in the tip of a pen, wand or projected device. According to an embodiment, an identifier is read when the tip of the pen or device moves across an identifier (e.g., bars of a bar code identifier) in a steady motion. A photodiode measures the intensity of the light reflected back from the light source and generates a waveform that is used to measure details of the identifier (e.g., the widths of the bars and spaces in a bar code). According to an embodiment, dark objects (e.g., bars) in an identifier absorb light and white objects (e.g., white spaces) reflect light so that the voltage waveform generated by a photodiode is a representation of the dark and white portions (e.g., bar and space pattern) of the identifier. According to an embodiment, this waveform is decoded by the scanner in a manner similar to the way Morse code dots and dashes are decoded.

[0049] Laser scanners are similar to pen type readers except that they may use a laser beam as the light source and may employ a reciprocating mirror and / or a rotating prism to scan the laser beam back and forth across the identifier. Similar to a pen type reader, a photodiode is used to measure the intensity of the light reflected back from the identifier. In pen readers and laser scanners, the light emitted by the reader often is tuned to a specific wavelength (e.g., frequency) and the photodiode is designed to detect modulated light of the same frequency.

[0050] CCD readers (also referred to as LED scanners or CCD detectors) use an array of (e.g., hundreds of) tiny light detectors lined up in a row in the head of the reader. Each detector can function as a single photodiode that measures the intensity of light immediately in front of it. Each individual light detector in the CCD reader often is small and because there are a plurality of detectors lined up in a row, a voltage pattern identical to the pattern in an identifier (e.g., a bar code) is generated in the reader by sequentially measuring the voltages across each detector in the row. A difference between a CCD reader and a pen or laser scanner sometimes is the CCD reader is measuring emitted ambient light from an identifier whereas a pen or a laser scanner is measuring reflected light of a specific frequency originating from the scanner itself.

[0051] According to an embodiment, a camera-based reader or 2D imaging scanner also may be used. Such a device often makes use of a small video camera that can capture an image of an identifier. According to an embodiment, a reader uses a digital image processing technique to decode the identifier. Video cameras use the same or a similar CCD technology as used for a CCD identifier reader except that instead of having a single row of detectors, a video camera has hundreds of rows of detectors arranged in a two dimensional array so that they can generate an image.

[0052] According to the invention, a reader comprises one or more components configured to detect CSE identifying information. A reader may comprise a single component or may comprise an assembly of two or more components (e.g., a reader assembly 800).

An electrical reader can detect the identity, presence, absence and / or location of a CSE according to certain open and closed circuits, where the circuits are open and / or closed as a direct result of the installation and / or removal of a CSE, or a portion thereof, from a rack or rack component. According to an embodiment, an identifier configured for detection by an electrical reader comprises a chip, memory or the like that provides additional information (e.g., binary information) to a rack system upon detection by a reader.

[0056] According to an embodiment, a reader may detect a signal emitted from a CSE identifier i, and in certain embodiments detect a signal first generated by the reader and then transmitted back to the reader from the CSE identifier (e.g., reflected by the identifier). According to an embodiment, a signal transmitted to a reader from an CSE identifier may be processed or decoded by the reader in some embodiments, and the processed signal may be forwarded to another part of a rack system (e.g., processor and / or controller). According to an embodiment, a signal is two or more signals (e.g., 2 or more signals, 3 or more signals, 4 or more signals, or more than 5 signals). In certain embodiments, each signal is the same signal, and in other embodiments, each signal is a different signal.

[0110] Provided herein are exemplary methods for monitoring contaminants in a rack (e.g., a rodent containment cage rack) that can be performed by a cage rack system according to the invention. According to an embodiment, a method for monitoring contaminants comprises detecting CSE identifying information on a component of a rack (e.g., a CSE) and performing one or more contaminant monitoring operations utilizing the CSE identifying information detected. According to an embodiment, CSE identifying information is detected by one or more readers. According to an embodiment, a method for monitoring contaminants comprises detecting CSE identifying information from a CSE identifier. According to an embodiment, the method comprises determining the presence and / or absence of a CSE or a portion thereof. The presence of a CSE is often determined when a CSE, or portion thereof, is in effective connection with a component of a rack.

[0111] According to an exemplary method that can be performed by a cage rack system according to the invention for monitoring contaminants in a rack, said method comprises providing a CSE in effective connection with a rack component where the CSE comprises CSE identifying information, and the CSE identifying information comprises an identifier. The identifier is detected, thereby providing CSE identifying information to a rack component (e.g., a rack component coupled to a reader). The method for monitoring contaminants in a rack comprises detecting CSE identifying information by a reader, optionally processing CSE identifying information, sending CSE identifying information from the reader to one or more rack components coupled to the reader and / or sending notifications to a user (e.g., as illustrated in FIG. 17). According to an embodiment, a reader is coupled to one or more components comprising a microprocessor, memory and / or instructions configured to utilize CSE identifying information to perform one or more contaminant monitoring operations. For example, in certain embodiments a CSE, or a portion thereof, in installed on a rack 941, the presence of the CSE is detected by a reader 942 and notification of the presence of the reader is sent to display or indicator, thereby notifying a user of the presence of an installed CSE 943. According to an embodiment, a method for monitoring contaminants in a rack comprises providing notification or confirmation of the presence and / or absence of a CSE (e.g., a CSE in effective connection with the rack component). CSE identifying information may be transferred to and / or from one or more components of a rack. After detection of the presence of a CSE by reader, CSE identifying information may be processed and / or stored in the memory of a rack component 944. In certain embodiments when a CSE is first detected by a reader, a time (e.g., a time stamp) is associated with installation of the CSE, often initiating a sampling protocol 945. A sampling protocol may track how long a CSE has been installed in a rack. A method for monitoring contaminants in a rack may comprise providing notification of a time (e.g., a recommended time) for removal and testing of the CSE according to CSE identifying information. After a predetermined amount of time has passed, a sampling protocol may send notification to a user recommending that the CSE is tested for the presence, absence or amount of a contaminant 946. After notification is received, at any suitable time, a user may remove a CSE, or portion thereof, and test it for the presence, absence or amount of a contaminant 947. When a CSE is removed, a reader may detect the absence of a CSE, and CSE identifying information is again logged into memory (e.g., a database, a log). According to an embodiment, a method of monitoring contaminants comprises replacing a CSE, or a portion thereof, from a rack or rack component. According to an embodiment, a first CSE is removed for testing and a second CSE, which may comprise a unique CSE identifier, replaces the first CSE. For example, a new CSE may be installed, initiating a new series of steps 941 through 948.

[0112] According to an exemplary method of monitoring contaminants that can be performed by a cage rack system according to the invention, the method may comprise testing and / or sampling a CSE or a portion thereof. According to certain embodiments, testing and / or sampling a CSE, or a portion thereof, comprises sending a CSE, or portion thereof, to a third party where test results are obtained and / or received from a third party. A CSE, or portion thereof, may be tested at any suitable location by any suitable method. Testing a CSE often comprises detecting and / or determining the presence, absence and / or amount of a contaminant on a CSE or a portion thereof (e.g., a sampling element). A suitable method and / or kit (e.g., a commercially available kit) can be used for detecting and / or determining the presence, absence and / or amount of a contaminant on a CSE. Non-limiting examples of methods that can be used to detect and / or determine the presence, absence and / or amount of a contaminant on a CSE include suitable PCR- amplification and / or sequencing techniques using primers and / or probes specific for known pathogens, culturing techniques (e.g., for culturing certain bacteria, molds and viruses), microscopic techniques (e.g., to identify certain parasites, insects, molds and bacteria), the like or combinations thereof. According to an embodiment, test results obtained from testing and / or sampling a CSE, or portion thereof, are confirmed by using a different method. According to an embodiment, CSE test results are confirmed by testing one or more animals (e.g., sentinel animals) in a rack from which a CSE was obtained.

[0113] Test results obtained from a CSE are often associated with a CSE identifier and / or with CSE identifying information. After test results are obtained, the test results may be entered into a rack and the results are associated with unique CSE identifier 949 obtained from the CSE that was tested. According to an embodiment, a CSE identifier is detected one or more times by a reader before, during and / or after testing a CSE. CSE identifying information associated with test results may be entered into a system by a user and / or by a portable reader. The test results may be associated with CSE identifying information related to, for example, the CSE tested, the previous location of the CSE in a rack and / or cages that are affected by the test results. Notification of test results may be sent to a display or user 951. An exemplary method for monitoring contaminants in a rack may comprise detecting contaminants using a CSE comprising a detector. An exemplary method for monitoring contaminants in a rack comprise detecting CSE identifying information and / or detecting the presence, absence and / or amount of an animal pathogen in real-time. According to certain embodiments, a detector is not removed from a rack for testing. According to an embodiment, a detector may comprise a dynamic sampling element. A dynamic sampling element can provide data and / or information to a rack system during or after a contaminant is detected without requiring removal of a CSE, or a portion thereof, from a rack.

[0114] According to an embodiment, a method for monitoring contaminants in a rack comprises, after obtaining test results, generating instructions for adjusting a rack and / or adjusting a rack according to the test results and the CSE identifying information. According to an embodiment, test results are processed by a rack component (e.g., a microprocessor) and one or more recommended instructions are generated and sent to a display and / or user 952. Non-limiting examples of instructions include instructions to confirm results using a suitable method, retest CSE, or a portion thereof, treat affected animals, remove affected animals, quarantine affected animals, cease animal breeding activities, collect embryo's from animals, stop or redirect air flow to certain cages, euthanize animals, sterilize rack, sterilize rack components, the like or combinations thereof.Drawing Elements
