Example embodiments of the present disclosure relate generally to a printed label and, more particularly, to systems and methods for predicting a printed label's life.
Generally, a printed label comprising printed machine readable indicia, fades over time. Fading of such labels deems the machine readable indicia unreadable, which may be desirable and may cause errors in tracking of an object/a human (when the machine readable indicia is utilized for tracking the object/human).
Various embodiments illustrated herein disclose a method comprising receiving, by a processor, one or more patient characteristics associated with a first patient, wherein the one or more patient characteristics comprises at least a type of sanitization, and/or a frequency of sanitization usage. The method further includes receiving, by the processor, one or more image characteristics associated with an image of a patient bracelet worn by the first patient. The method further includes training, by the processor, a machine learning (ML) model defining a relation between the one or more patient characteristics and the one or more image characteristics, wherein the ML model is utilized to predict a count of days until the patient bracelet, associated with a second patient, deems unusable. Additionally, the method includes generating, by the processor, an instruction to a printing apparatus to print a new patient bracelet for the second patient based on the count of days being less than a predetermined number of days threshold.
Various embodiments illustrated herein disclose a central server comprising a memory device storing one or more instructions. Further, the central comprises a processor communicatively coupled to the memory device, wherein the processor is configured to receive one or more patient characteristics associated with a first patient, wherein the one or more patient characteristics comprises at least a type of sanitization, and/or a frequency of sanitization usage. Additionally, the processor is configured to receive one or more image characteristics associated with an image of a patient bracelet worn by the first patient. Further, the processor is configured to train a machine learning (ML) model defining a relation between the one or more patient characteristics and the one or more image characteristics, wherein the ML model is utilized to predict a count of days until the patient bracelet, associated with a second patient, deems unusable. Furthermore, the processor is configured to generate an instruction to a printing apparatus to print a new patient bracelet for the second patient based on the count of days being less than a predetermined days threshold.
The description of the illustrative embodiments can be read in conjunction with the accompanying figures. It will be appreciated that for simplicity and clarity of illustration, elements illustrated in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements are exaggerated relative to other elements. Embodiments incorporating teachings of the present disclosure are shown and described with respect to the figures presented herein, in which:
Some embodiments of the present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the disclosure are shown. Indeed, these disclosures may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
Unless the context requires otherwise, throughout the specification and claims which follow, the word “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open sense, that is as “including, but not limited to.”
Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, one or more particular features, structures, or characteristics from one or more embodiments may be combined in any suitable manner in one or more other embodiments.
The word “example” or “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other implementations.
If the specification states a component or feature “may,” “can,” “could,” “should,” “would,” “preferably,” “possibly,” “typically,” “optionally,” “for example,” “often,” or “might” (or other such language) be included or have a characteristic, that a specific component or feature is not required to be included or to have the characteristic. Such component or feature may be optionally included in some embodiments, or it may be excluded.
The term “electronically coupled,” “electronically coupling,” “electronically couple,” “in communication with,” “in electronic communication with,” or “connected” in the present disclosure refers to two or more components being connected (directly or indirectly) through wired means (for example but not limited to, system bus, wired Ethernet) and/or wireless means (for example but not limited to, Wi-Fi, Bluetooth, ZigBee), such that data and/or information may be transmitted to and/or received from these components.
The term “indicium” has been broadly intended to include any indicia, or a machine readable code including Linear symbols, 2D barcodes (such as QR code, and Datamatrix codes), RFID tags, IR tags, near-field-communication (NFC) tags, and characters that are readable by a computing device (for example, an indicia scanner). Indicia are typically graphical representations of information (e.g., data), such as product numbers, package tracking numbers, patient barcode symbology identifier numbers, medication tracking identifiers, personnel barcode symbology identifier numbers, etc.
The term “quality” may refer to standard or protocol based on which content may be evaluated or compared with each other. For example, quality of an image may be evaluated based on sharpness of the image, noise in the image, dynamic range of the image, and/or the like. In some examples, the quality of the image may be further evaluated based on the quality of certain portions of the image. For example, the quality of the image may be evaluated based on quality of indicium in the image. To this end, the quality of the indicium may be evaluated based on ANSI X3.182, ISO15415, and ISO/IEC 15416 standards.
A typical printed label fades in due course of time. In some scenarios, where the printed label comprises a printed machine readable indicia, the machine readable indicia may fade in due course of time. Indicia scanner may not be able to scan and decode the faded machine readable indicia. Accordingly, tracking objects with such faded machine readable indicia may be error prone (since scanning and decoding of the faded machine readable indicia may be unsuccessful).
For example, the printed label (with the machine readable indicia) may correspond to a patient bracelet printed for one or more patients admitted to a hospital. Such patient bracelets are utilized for tracking the patients within the hospital premises. Additionally or alternately, such patient bracelets are utilized to track a first set of patient characteristics. In some examples, the first set of patient characteristics includes, but not limited to, a type of disease associated with a patient, an age of the first patient, a name of the patient, a location of the patient within the hospital premises, a traversal history of the patient within the hospital premises, and/or the like. In scenarios, where the machine readable indicia on the patient bracelet fades, scanning and decoding of the machine readable indicia on the patient bracelet may fail, leading of errors monitoring of the patient.
Embodiments illustrated herein disclose systems and methods for predicting a life of a printed label. In an example embodiment, the printed label may correspond to a label or a medium on which a printer may print content. In some examples, the printed content may include a machine readable indicia. In an example embodiment, the machine readable indicia may be configured to store a first set of object characteristics pertaining to an object on which the printed label is attached. For example, in a hospital environment, the machine readable indicia is printed on a patient bracelet and is configured to store a first set of patient characteristics. In an example embodiment, the first set of patient characteristics may include, but not limited to, a name of the patient (on which the patient bracelet is attached), an age of the patient (on which the patient bracelet is attached), and a disease associated with the patient (on which the patient bracelet is attached). In some examples, the patient bracelet may facilitate monitoring of a location of the patient within the hospital premises. For example, when a patient is moved from one ward to another, the patient bracelet is scanned by an attendant of each ward, which allows monitoring of the patient's location within the hospital premises.
Additionally or alternately, the system includes an operator computing device that is configured to receive input from the attendant in the hospital pertaining to the patient. For example, the attendant may provide input to the operator computing device pertaining to a second set of patient characteristics associated with the patient. In an example embodiment, the second set of patient characteristics include, but are not limited to, a traversal history of the patient within the hospital, a type of sanitization used to disinfect the patient, a frequency of sanitization, and/or the like. In some examples, the first set of patient characteristics and the second set of patient characteristics may constitute the one or more patient characteristics. In some examples, the attendant may utilize the operator computing device to input both the first set of patient characteristics and the second set of patient characteristics. In response to inputting the one or more patient characteristics (i.e., the first set of patient characteristics and the second set of patient characteristics), the operator computing device may be configured to transmit the one or more patient characteristics to a central server.
In an example embodiment, the system further includes an indicia scanner that is configured to scan and decode the machine readable indicia, printed on the patient bracelet, to retrieve the first set of patient characteristics. Additionally or alternately, the indicia scanner may be configured to determine one or more image characteristics associated scanned image of the patient bracelet. The one or more image characteristics may include, but not limited to, a quality measure of the patient bracelet, information whether the decoding of the machine readable indicia is successful (hereinafter referred to as decode status). For example, the indicia scanner may be configured to determine the quality measure of the patient bracelet by determining the quality of the machine readable indicia (printed on the patient bracelet) based on ANSI X3.182, IS015415, and ISO/IEC 15416 standards. In some examples, the decoding of the machine readable indicia may fail, as the machine readable indicia may have defects (such as but not limited to fading of the machine readable indicia). Additionally or alternately, the indicia scanner may be configured to transmit the decode status to the central server. In some examples, the decode status may be indicative of the quality measure of the patient bracelet. For example, if the decoding of the machine readable indicia is successful, the decode status will indicate “successful”. Accordingly, the quality of the patient bracelet is good. Similarly, if the decoding of the machine readable indicia is unsuccessful, the decode status will indicate “unsuccessful”. Accordingly, the quality of the patient bracelet has degraded.
In an example embodiment, the central server may be configured to receive the one or more patient characteristics from the operator computing device (i.e., the second set of patient characteristics) and the indicia scanner (i.e., the first set of patient characteristics). Additionally or alternately, the central server may be configured to receive the one or more image characteristics from the indicia scanner. In some examples, the central server may be configured to generate a training data based on the one or more patient characteristics and the one or more image characteristics (associated with image scanned by the indicia scanner). In an example embodiment, the training data. In an example embodiment, the training data may include one or more features and one or more labels. The one or more features of the training data may include, but are not limited to, the first time period between successive scanning of the machine readable indicia, the current location of the patient within the hospital premises based on scanning of the machine readable indicia, a type of sanitizer historically used to disinfect the patient, a frequency of sanitizer usage, an age of the patient, the quality measure of the patient bracelet(received from indicia scanner), the decode status, and/or a disease associated with the patient. The one or more labels of the training data may include, but are not limited to, the count of days after which the patient bracelet had defects.
In an example embodiment, the central server may be further configured to train a machine learning (ML) model based on the training data. In an example embodiment, the ML model may define one or more relations and/or rules amongst the one or more features of the training data and the one or more labels of the training data. Thereafter, the central server may be configured to predict a second count of days until the patient bracelet is deemed unreadable or damaged. In some examples, the central server may transmit an instruction to print a new patient bracelet in a scenario where the second count of days is less than a predetermined threshold.
The disclosed embodiments encompass numerous advantages. For example, the disclosed embodiments allow to proactively determine a count of days until the patient bracelet is damaged. Accordingly, the central server may instruct the printer to proactively print the patient bracelet. To this end, the errors in monitoring of the patient (due to damaged patient bracelet) is avoided.

In some devices, multiple processors may be provided dedicated to wireless communication functions and one processor dedicated to running other applications. Software applications may be stored in the internal memory before they are accessed and loaded into the processors. The processors may include internal memory sufficient to store the application software instructions. In many devices, the internal memory may be a volatile or nonvolatile memory, such as flash memory, or a mixture of both. The memory can also be located internal to another computing resource (e.g., enabling computer readable instructions to be downloaded over the Internet or another wired or wireless connection).
The first memory device 204 may include suitable logic, circuitry, and/or interfaces that are adapted to store a set of instructions that is executable by the first processor 202 to perform predetermined operations.

The patient characteristics determination unit 210 may include suitable logic and/or circuitry that may enable the operator computing device 104 to automatically determine the first set of patient characteristics. For example, the patient characteristics determination unit 210 may be configured to instruct the indicia scanner 102 to capture an image of the patient bracelet, while the patient traverses through the hospital premises. Thereafter, based on the location where the indicia scanner 102 is installed or positioned, the operator computing device 104 may be configured to determine the ward in which the first patient is staying, and the traversal history of the first patient within the hospital premises, as is further described in conjunction with
The operation of the operator computing device 104 is further described in conjunction with
At step 302, the operator computing device 104 may include means such as the first processor 202, I/O device interface unit 208, and/or the like for presenting an interface on a display screen associated with the operator computing device 104.

The flowchart 300B explain the automatic determination of the first set of patient characteristics.
At step 304, the indicia scanner 102 may include means such as the first processor 202, I/O device interface unit 208, and/or the like for causing the indicia scanner 102 to trigger periodically. For example, the I/O device interface unit 208 may cause the indicia scanner 102 to trigger after 30 mins. Upon triggering the indicia scanner 102 may be configured to capture the image of the field of view. If the field of view includes the patient bracelet, the indicia scanner 102 may be configured to decode the machine readable indicia in the patient bracelet and may be configured to transmit the decoded data to the operator computing device 104. In an example embodiment, the decoded data includes information pertaining to name of the first patient, the age of the first patient, and disease associated with the first patient. Additionally or alternately, the indicia scanner 102 may be configured to transmit the decode status as “success” to the operator computing device 104. If the indicia scanner 102 fails to identify the patient bracelet within the field of view, the indicia scanner 102 may be configured to transmit information that “no patient bracelet identified in field of view” to the operator computing device 104. Additionally or alternately, if the indicia scanner 102 fails to decode the machine readable indicia in the patient bracelet (present in the field of view of the indicia scanner 102), the indicia scanner 102 may be configured to transmit the decode status as “fail” to the operator computing device 104.
At step 306, the operator computing device 104 may include means such as the first processor 202, the patient characteristics determination unit 210, and/or the like, for determining whether the patient bracelet is present in the field of view of the indicia scanner 102. For example, the operator computing device 104 may be configured to check for the reception of the information “no patient bracelet identified in field of view” from the indicia scanner 102. If the patient characteristics determination unit 210 determines that the operator computing device 104 has received the information “no patient bracelet identified in field of view”, the patient characteristics determination unit 210 may be configured to repeat the step 304. However, if the patient characteristics determination unit 210 determines that the operator computing device 104 has not received the information “no patient bracelet identified in field of view”, the patient characteristics determination unit 210 may be configured to perform the step 308.
At step 308, the operator computing device 104 may include means such as the first processor 202, the patient characteristics determination unit 210, and/or the like, for determining whether the decode status is “fail”. If the patient characteristics determination unit 210 determines that the decode status is “fail”, the patient characteristics determination unit 210 may configured to perform the step 310.
However, if the patient characteristics determination unit 210 determines that the operator computing device 104 has received the decoded data, the patient characteristics determination unit 210 may be configured to perform the step 312.
At step 310, the indicia scanner 102 may include means such as the first processor 202, the patient characteristics determination unit 210, the I/O device interface unit 208, and/or the like, for presenting an interface to the attendant that includes fields corresponding the one or more patient characteristics. Thereafter, the patient characteristics determination unit 210 may be configured to perform the step 318.

As discussed, the decoded data includes information pertaining to the name of the first patient, the age of the first patient, and disease associated with the first patient. In an example embodiment, the patient characteristics determination unit 210 may consider the name of the first patient, the age of the first patient, and disease associated with the first patient, as the first set of patient characteristics associated with the first patient.
Additionally or alternately, at step 314, the operator computing device 104 may include means such as the first processor 202, the patient characteristics determination unit 210, and/or the like, for determining a location of the first patient within the hospital premises based on a location of the indicia scanner 102 from which the operator computing device 104 received the decoded data. In an example embodiment, the patient characteristics determination unit 210 may refer to look-up table (table 1) to determine the location of the indicia scanner 102 in the hospital premises. In an example embodiment, the operator computing device 104 may be configured to consider the location of the indicia scanner 102 in the hospital premises as the location of the first patient in the hospital premises. As discussed in
Additionally or alternately, the patient characteristics determination unit 210 may be further configured to determine traversal history of the first patient. In an example embodiment, the traversal history may correspond to list of locations where the first patient has visited within the hospital premises. In an example embodiment, the patient characteristics determination unit 210 may be configured to append the determined location of the first patient to the traversal history. Further, the patient characteristics determination unit 210 may be configured to add the traversal history of the first patient in the first set of patient characteristics.
At step 316, the indicia scanner 102 may include means such as the first processor 202, the patient characteristics determination unit 210, the I/O device interface unit 208, and/or the like, for presenting an interface to the attendant that includes fields corresponding the second set of patient characteristics. In an example embodiment, the second set of patient characteristics comprises, but not limited to, the type of sanitization used for disinfecting the first patient, and the frequency of sanitization. Thereafter, the patient characteristics determination unit 210 may be configured to perform the step 318.
In some examples, the patient characteristics determination unit 210 may determine the frequency of sanitization automatically. For example, the patient characteristics determination unit 210 may be configured to determine the frequency of the sanitization based on the traversal history. In such an embodiment, the patient characteristics determination unit 210 may utilize a hypothesis that the first patient may be sanitized every time the first patient is moved or traversed to a location. Accordingly, based on the traversal history of the first patient, the patient characteristics determination unit 210 may determine the frequency of sanitization. For instance, the first patient is moved between locations twice in three days. In such an embodiment, the patient characteristics determination unit 210 may determine the frequency of sanitation as 0.6 times per day. Additionally or alternately, the patient characteristics determination unit 210 may further consider a predetermined the count of times a patient is sanitized to determine the frequency of the sanitization. For example, the a predetermined the count of times a patient is sanitized in a day is 2 time per day. Accordingly, the frequency of the sanitization is 2.6 time per day.
At step 318, the operator computing device 104 may include means such as the first processor 202, the patient characteristics determination unit 210, and/or the like, for transmitting the one or more patient characteristics to the central server 108.

In such an embodiment, the central server 108 may be configured to store the ideal image, as is described later in conjunction with
To compare the modified image with the ideal image, the image processing unit 410 may be configured to determine an intersection between the modified image and the ideal image. In an example embodiment, the intersection between the image and the ideal image facilitates highlighting common regions between the two images. Additionally, the intersection between the image and the ideal image identifies regions in the image that are dissimilar from the ideal image. Since the ideal image of the patient bracelet has no defects, therefore, intersection between the ideal image and the image may facilitate identification the regions on the patient bracelet that have faded away or have smudges based on the intersection between the image and the ideal image.

However, if the third processor 702 determines that the difference is greater than the predetermined days threshold, the third processor 702 may be configured to repeat the step 902. In some examples, the predetermined day threshold is less than the count of days until the patient bracelet associated with a new patient is not usable. Further, in some examples, the predetermined threshold is defined during configuration of the software. In an alternate embodiment, the predetermined threshold is configurable and may be defined in real time (i.e., during execution of the flowchart 800).
At step 910, central server 108 may include means such as the third processor 702 and/or the like for transmitting an instruction to the printing apparatus 110 to print a new patient bracelet. Since the predetermined day threshold is less than the count of days until the patient bracelet associated with a new patient is not usable, the central server 108 may print a new patient bracelet prior to the patient bracelet becoming unreadable.
In some examples, the scope of the disclosure is not limited to having three separate computing devices (indicia scanner 102, the operator computing device 104, and the central server 108) to perform the aforementioned operation. In an example embodiment, the system environment 100 may include only one computing device that is capable of performing the operations of the indicia scanner 102, the operator computing device 104, and the central server 108
In an example embodiment, the scope of the disclosure is not limited to predicting the life of the patient bracelet in the hospital environment. The disclosed embodiment may be applicable on any printed label utilized any domain. For example, disclosed systems and methods may be utilized to predict the printed label in logistic environment. In such an embodiment, instead of the one or more patient characteristics, the attendant may utilize operator computing device 104 for transmitting one or more object characteristics. In an example embodiment, the one or more object characteristics may include, but not limited to, a destination of the object, a traversal history of the object, a storage temperature of the object, a type of sanitization used to disinfect the object, and/or a frequency of sanitization. In an example embodiment, the central server 108 upon receiving the one or more object characteristics, the central server 108 may be configured to train the ML model the one or more object characteristics and the one or more image characteristics. Thereafter, the central server 108 may be configured to utilize the ML model to predict the life of the printed label attached on new object based on the one or more object characteristics associated with the new object.
For example, in a shipping warehouse, the operator computing device 104 may input the one or more object characteristics that may include a number of times an object was handled by an operator, a number of times the object of sanitized, the traversal history of the object, storage temperature of the object, a type of sanitization used to disinfect the object, and/or a frequency of sanitization. For example, the operator of the operator computing device 104 may input that an object was sanitized every 5 hours, the object was handled by 10 different workers in the warehouse, the object was previously handled at 5 different locations, and/or the like. Thereafter, the central server 108 may be configured to train the ML model the one or more object characteristics and the one or more image characteristics. Thereafter, the central server 108 may be configured to utilize the ML model to predict the life of the printed label attached on new object based on the one or more object characteristics associated with the new object.
