Description

SYSTEM, DEVICE, PRODUCT, APPARATUS AND METHOD FOR READING SYRINGE INFORMATION CROSS REFERENCE TO RELATED APPLICATION This application claims priority to the United States Provisional Application serial no. 62 / 986.943 filed on March 9, 2020, entitled System, Device, Product, Apparatus, and Method for Reading Syringe Information, the full disclosure of which is hereby incorporated by reference in its entirety. BACKGROUND 1. Field This disclosure relates generally to RFID communications and, in some non-limiting embodiments or aspects, to a system, device, product, apparatus and / or method for reading information from syringes using RFID communications. 2. Technical considerations 2D barcode readers can be used to decode 2D barcodes on syringes. These readers may employ a complex optical system that is manually activated when a syringe is connected. This electromechanical activation can be unreliable due to the relatively tight tolerance control required to couple the various components of an injection system to the syringe. Furthermore, the optical system for a 2D barcode reader may use an expensive cylindrical lens in a light transmission path, for which factory calibration is relatively difficult and throughput rates are relatively low. Consequently, there is a need to improve the reading of information from the syringe.

The computing device may be a mobile device, a desktop computer, or similar equipment. Additionally, the term computer may refer to any computing device that includes the components necessary to receive, process, and output data, and typically includes a display, a processor, memory, an input device, and a network interface.An application or application programming interface (API) refers to computer code, a set of rules, or other data arranged in a machine-readable format that can be executed by a processor to facilitate interaction between software components, such as a client-side front end and / or a server-side back end for receiving data from the client.

Furthermore, multiple computers, e.g., servers or other computerized devices, such as POS devices, that communicate directly or indirectly in the network environment may constitute a system, such as a merchant's POS system. Improved systems, devices, products, apparatus and / or methods are provided for reading syringe information. Radio frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system typically includes an RFID reader and multiple RFID tags. The RFID reader communicates wirelessly with the RFID tags. RFID tags can be passive tags, which have no external power source and are powered wirelessly by the RFID reader, or active tags, which are powered by a local or internal power source (e.g., a battery). RFID tags include an antenna and a device for electronically storing information and / or data to be read from the RFID reader (e.g., a memory chip). RFID typically operates in three main frequency ranges: Low Frequency (LF) (e.g., around 120–150 kHz), High Frequency (HF) (e.g., around 13.56 MHz), and Ultra High Frequency (UHF) (e.g., around 865–868 MHz in Europe and 902–928 MHz in the United States). The LF and HF frequency ranges utilize magnetically coupled systems where the fields of the RFID reader's antenna and the fields of the RFID tag must be aligned for the reader to read the tag. The LF and HF frequency ranges work well if the orientation of the RFID tags relative to the reader can be controlled. In contrast, in the UHF frequency range, RFID tags can still be read even if their field orientation is not directly aligned with the reader's antenna.Consequently, UHF RFID tags may perform better in situations where the orientation of the RFID tags with respect to the RFID reader cannot be easily controlled and / or known. The area in which an RFID reader can read UHF RFID tags can be controlled by changing the system's transmit power and / or receive signal gain to make the area smaller or larger. However, UHF RFID lacks a mechanism to select a single or specific tag in a particular location. For example, a UHF RFID reader designed to read syringe information from RFID tags on syringes may not be able to identify or differentiate a syringe intended for scanning and / or connection to an injection system from other syringes in the surrounding area. ivia / t / zuzz / uzz zo z The embodiments or non-limiting aspects of this disclosure relate to a system, a reader, and a method thereof, comprising a first antenna, a second antenna separate from the first antenna, an RFID reader circuit, and a processor. The first antenna and the second antenna are connected to the RFID reader circuit. The first antenna is configured to receive a first signal from an RFID tag. The second antenna is configured to receive a second signal from the RFID tag. The processor controls the RFID reader circuit to determine a first value of a signal parameter associated with the RFID tag based on the first signal and a second value of the signal parameter associated with the RFID tag based on the second signal. It receives the first and second values ​​from the RFID reader circuit and determines, based on the first and second values, whether the RFID tag is located between the first and second antennas.In this way, a syringe that includes the RFID tag that is intended to be scanned and / or connected to an injection system can be identified or differentiated from other syringes in a surrounding area that are not intended to be scanned and / or connected to an injection system.

For example, the reader device 102 may include one or more computer systems that include one or more processors (for example, one or more computer devices, one or more mobile computer devices, etc.). In some embodiments or non-limiting aspects, the reader device 102 may receive information (for example, from the first RFID tag 106, from at least one second RFID tag 110, etc.) via a ML / t / ZUZZ / U í í fO t RFID communication connection (e.g., via a UHF RFID communication connection, etc.), and / or communicate information (e.g., to the first RFID tag 106, to at least a second RFID tag 110, etc.) via an RFID communication connection.

For example, the first RFID tag 106 can include a first tag applied to the first syringe 104. As an example, the first RFID tag 106 can be attached to the body of the first syringe 104. At least one second RFID tag 110 may be attached to (e.g., removably attached, integrally formed with, etc.) at least one second syringe 108. For example, at least one second RFID tag 110 may include a second seal applied to at least one second syringe 108.

With reference now to Figures 2A and 2B, Figures 2A and 2B are diagrams of embodiments or non-limiting aspects of an implementation 200 of one or more systems and / or one or more devices of Figure 1. As shown in Figures 2A and 2B, the reader device 102 may include the first antenna 202, the second antenna 204 separate from the first antenna 202, the connector 206, the switch 207, the RFID reader circuit 208, the processor 210 (for example, a microcontroller, etc.), the indicator 212 (for example, a display, one or more LEDs, a speaker, etc.), first antenna shielding material 214 and / or second antenna shielding material 216.In some embodiments or non-limiting aspects, the reader device 102 may include a housing 220 that houses the first antenna 202, the second antenna 204, the connector 206, the switch 207, the RFID reader circuit 208, the processor 210, the indicator 212, the first antenna protection material 214, and / or the second antenna protection material 216. The first antenna 202 and the second antenna 204 can be connected to the RFID reader circuit 208. The first antenna 202 can be configured to receive a first signal from an RFID tag (e.g., the first RFID tag 106, at least a second RFID tag 110, etc.). The second antenna 204 can be configured to receive a second signal (e.g., a second signal different from the first signal received by the first antenna 202, etc.) from an RFID tag (e.g., the first RFID tag 106, at least a second RFID tag 110, the same RFID tag from which the first antenna 202 received the first signal, etc.). Connector 206 can be configured to connect to a syringe (e.g., the first syringe 104, at least one second syringe 108, etc.). Connector 206 can be located between the first antenna 202 and the second antenna 204. The first antenna 202 and the second antenna 204 can be located at the same distance from connector 206 (e.g., the same distance from the longitudinal axis of connector 206, etc.). For example, as shown in Figures 2A and 2B, a distance D1 between the first antenna 202 and a center or longitudinal axis of connector 206 can be equal to a distance D2 between the second antenna 205 and a center or longitudinal axis of connector 206. ivia / t / zuzz / uzz zo z The RFID reader circuit 208 can be configured to determine a signal parameter value (e.g., a Received Signal Strength Indication (RSSI), etc.) associated with an RFID tag based on a signal (e.g., a UHF RFID signal, etc.) received from that RFID tag. For example, the RFID reader circuit 208 (e.g., under the control of processor 210, etc.) can determine a first signal parameter value associated with the RFID tag based on the first signal received by the first antenna 202 and a second signal parameter value based on the second signal received by the second antenna 204. Similarly, the RFID reader circuit 208 (e.g., under the control of processor 210, etc.) can determine an RSSI value from the first signal received by the first antenna 202 and an RSSI value from the second signal received by the second antenna 204. Switch 207 can be configured to be actuated in response to a syringe being connected (e.g., the first syringe 104, etc.) to connector 206. For example, processor 210 can be in electrical communication with switch 207, and processor 210 can be programmed and / or configured to control RFID reader circuit 208 to determine the first and second values ​​in response to an actuation of switch 207. In some embodiments or non-limiting aspects, the RFID reader circuit 208 includes a switching circuit (e.g., an RFID switch, a multiplexer, etc.). For example, the RFID reader circuit 208 may include an ST25RU3993 module. As an example, the first antenna 202 and the second antenna 204 may be connected to the switching circuit, and the switching circuit may be configured to selectively couple the first antenna 202 and the second antenna 204 to the RFID reader circuit 208. In such an example, the processor 210 may, using the switching circuit, control the RFID reader circuit 208 to selectively read a first signal from an RFID tag with the first antenna 202 and a second signal from that same RFID tag with the second antenna 204.The first RFID tag signal received with the first antenna 202 and the second signal from the same RFID tag received with the second antenna 204 can each include a unique identifier associated with the RFID tag and the RFID reader circuit 208 (and / or the processor 210) can distinguish the first and second signals from the same RFID tag (e.g., from the first RFID tag 106, etc.) from the first and / or second signals received with the first antenna 202 and / or the second antenna 204 from one or more RFID tags (e.g., the at least one second RFID tag 110 on the at least one second syringe 108, etc.) based on the unique identifiers. MA / í í fO t included in the received signals. However, the embodiments or non-limiting aspects are not limited to the same, and the RFID reader circuit 208 may include separate RFID reader modules (e.g., separate ST25RU3993 modules, etc.) for each of the first antenna 202 and the second antenna 204 to respectively read the first signal of the RFID tag with the first antenna 202 and the second signal of that same RFID tag with the second antenna 204. The processor 210 can be connected (e.g., electrically) to the RFID reader circuit 208. The processor 210 can receive from the RFID reader circuit 208 a first value of a signal parameter associated with an RFID tag and a second value of the same signal parameter, and determine, based on the first and second values, whether the RFID tag is located between the first and second antennas (e.g., whether a syringe containing the RFID tag is connected to connector 206). For example, the processor 210 can determine whether the first and second values ​​(e.g., the RSSI value of the first signal received by the first antenna 202 and the RSSI value of the second signal received by the second antenna 204) are substantially equal (e.g., within a tolerance threshold).As an example, processor 210 can determine a difference between the first and second signals and, in response to that difference satisfying a threshold, determine that the RFID tag associated with the same unique identifier included in those corresponding first and second signals is located between the first and second antennas (e.g., that a syringe containing the RFID tag is connected to connector 206, etc.). In such an example, a syringe containing the RFID tag that is connected to connector 206 might have substantially equal RSSI values ​​for the first and second signals.As an example, processor 210 might determine a difference between the first and second signal values ​​and, in response to the difference not meeting the threshold, determine that the RFID tag is not located between the first and second antennas (e.g., that the RFID tag is outside the first and second antennas, that a syringe containing the RFID tag is not connected to connector 206, etc.). In such an example, a syringe containing the RFID tag that is not connected to connector 206 might have substantially different RSSI values ​​(e.g., outside a tolerance threshold, etc.) for the first and second signals. The 212 indicator can be configured to provide an indication associated with the information included and / or associated with a signal received from an RFID tag (e.g., MA / t / ZUZZ / U í í ló t information included in a first signal received from an RFID tag with the first antenna 202, information included in a second signal received from that same RFID tag with the second antenna 204, etc.). In some embodiments or non-limiting aspects, an indication may include at least one of the following: a unique identifier associated with the RFID tag, an indication that a syringe associated with the RFID tag is connected upon connecting 206, an indication that the syringe associated with the RFID tag is not connected upon connecting 206, information associated with a medicinal product contained in the syringe associated with the RFID tag, or any combination thereof. In some embodiments or non-limiting aspects, the reader device 102 may communicate the indication and / or the information associated with it to the remote computer system 114. The first shielding material 214 can surround a portion of the first antenna 202.

The second shielding material 216 can surround a portion of the second antenna 204. For example, the second shielding material 216 can be configured so that the second antenna 204 forms a directional beamforming antenna (e.g., in a direction toward the top of Figure 2A, etc.).

At least one third antenna 218 can be configured to receive at least one third signal (e.g., at least one third signal different from the first signal received by the first antenna 202 and the second signal received by the second antenna 204, etc.) from an RFID tag (e.g., the first RFID tag 106, at least one second RFID tag 110, the same RFID tag from which the first antenna 202 received the first signal and from which the second antenna 204 received the second signal, etc.). For example, the RFID reader circuit 208 (e.g., under the control of the processor 210, etc.) can determine at least one third value of the signal parameter associated with the RFID tag based on at least one third signal received by at least one third antenna 218. As an example, the RFID reader circuit 208 (e.g., under the control of the processor 210, etc.)) can determine an RSSI value of the first signal received by the first antenna 202, determine an RSSI value of the second signal received by the second antenna 204 and determine an RSSI value of at least a third signal received by the at least a third antenna 218.

For example, the processor 210 can determine whether the first, second, and third values ​​(e.g., the RSSI value of the first signal received by the first antenna 202, the RSSI value of the second signal received by the second antenna 204, and the RSSI value of the at least a third signal received by the at least a third antenna 218, etc.) are substantially equal to each other (e.g., within a tolerance threshold, etc.).As an example, the processor 210 can determine one or more differences between the first value, the second value, and the third value and, in response to the determined difference or differences that satisfy one or more threshold differences, determine that the RFID tag associated with the same unique identifier included in those corresponding first, second, and third signals is located between the first antenna, the second antenna, and at least one third antenna (e.g., that a syringe including the RFID tag is connected to connector 206, etc.).
