Definitions
- RFID tags may be wirelessly read when the RFID tag is brought into proximity with an RFID reader. Wirelessly reading RFID tags may allow information about the tagged product to be quickly obtained and processed.
- RFID tags there are generally less constraints upon reading a RFID tag than reading a barcode (e.g., direct line of sight between the barcode and the barcode reader), therefore using RFID tags in a situation where barcodes would suffice may save time. But, in some cases, wirelessly reading RFID tags may still be a time consuming process. For example, in situations where large numbers of products are being scanned, a worker may individually locate and scan the RFID tag on each product. The repetitive nature of this process may cause significant delays while each RFID tag is scanned and may be subject to human error (e.g., if the worker forgets to turn the RFID reader on, or if the worker accidentally omits scanning one or more items).
- the present invention generally provides methods and systems for reading information from a signal-emitting device, such as a wireless identification tag.
- the method includes providing an electronic reading device mounted to a body-worn harness adapted to be worn on a body of a user.
- the method further includes detecting a predefined physical configuration assumed by at least a portion of the body by determining that a pressure value measured via a pressure sensor connected to the body-worn harness is above a threshold pressure value.
- the electronic reading device is activated.
- the electronic reading device Upon being activated, the electronic reading device is configured to receive a signal from the signal-emitting device, the signal containing data pertaining to a physical object associated with the signal-emitting device.
- a method for reading a wireless identification tag may include measuring a pressure value via a pressure sensor connected to a hand-mounted device. If the pressure value measured via the pressure sensor is above a threshold pressure value, then the method may also include wirelessly reading tag data from the wireless identification tag via an antenna connected to the hand-mounted device.
- a tangible computer-readable medium containing a program product may be provided.
- the program product may perform an operation which may include measuring a pressure value via a pressure sensor connected to a hand-mounted device.

- a method for product management may include wirelessly reading tag data from an identification tag using a hand-mounted identification tag reader.
- the tag data may be transmitted from the hand-mounted identification tag reader to a first computing system.
- the first computing system may be configured to receive additional tag information corresponding to the tag data from a user.
- a method for product management may include activating a hand-mounted wireless identification tag reader in response to a pressure exerted against a pressure sensor of the hand-mounted wireless identification tag reader.
- the activated hand-mounted wireless identification tag reader may wirelessly read identification tag data from an identification tag located in a handle portion of a product.
- a device may include a hand-mounted device for reading a wireless identification tag.
- the device may also include an antenna connected to the hand-mounted device for performing communication with the wireless identification tag.
- the antenna may be positioned between a first digit of a user's hand and a second digit of the user's hand.
- a hand-mounted device may include a hand sensor, a wireless tag reader, and circuitry.
- the circuitry may be configured to perform an operation which may include determining, using the hand sensor, whether a user is wearing the hand-mounted device. If the user is wearing the hand-mounted device, the operation may include activating the wireless tag reader.
- the activated wireless tag reader may be configured to read wireless tag data from a wireless identification tag placed within a threshold distance from the wireless tag reader.
- a hand-mounted device may include a pressure sensor mounted on one or more of the digits of a hand of a user, a wireless tag reader, and circuitry configured to perform an operation.
- the operation may include measuring a pressure value via the pressure sensor, determining if the pressure value measured via the pressure sensor is above a threshold pressure value, and, if so, reading wireless tag data from a wireless identification tag.

- the antenna 106 may be located anywhere else on the user 112 .
- the antenna 106 may be connected to the reader/writer module 108 via a connection 208 .
- the connection 208 may include a twisted pair of wires to reduce induction between the wires.
- the switch 202 may be used to select one three operating modes of the reader/writer module 108 . If the switch is in the off position, the reader/writer module 108 is off, no pressure is being detected, and no read operation may be performed. If the switch is in the manual position, the reader/writer module 108 may be activated, and read operations may be continually occurring regardless of detection of pressure by the pressure sensor 104 . If the switch is in the automatic position, the reader/writer module 108 may be activated, detection of pressure by the pressure sensor 104 may take place, and read operations may occur if the pressure sensor 104 detects a pressure on the sensor.
- the reader/writer module 108 may provide auditory feedback to the user 112 when wireless identification tag data is received.
- the auditory feedback may be a short tone signifying a successful read of a wireless identification tag 120 , or may be speech identifying the read operation and details about the wireless identification tag 120 . Such feedback may enable the user 112 to more quickly identify misreads and correct errors as they occur.
- the glove 102 may include a sensor 222 which may be used to detect the hand of the user 102 (e.g., to detect when the glove is being worn).
- the sensor 222 may work in conjunction with the switch 202 .
- the reader/writer module 108 may only be used for reading or writing when the sensor 222 detects that there is a hand in the glove 102 and when the switch 202 is not in the off position. As described above, such reading and writing may further depend on whether the pressure sensor 104 detects a pressure.
- the sensor 222 may replace the function of the off position of the switch 202 .
- the switch 202 may have two positions: automatic read and manual read.
- the reader/writer module 108 may be automatically activated.
- the reader/writer module control circuitry 214 may automatically monitor the pressure sensor to determine whether to activate the antenna 106 as described below.
- the sensor 222 may replace the switch 202 .

In one embodiment, the method includes providing an electronic reading device mounted to a body-worn harness adapted to be worn on a body of a user. The method further includes detecting a predefined physical configuration assumed by at least a portion of the body by determining that a pressure value measured via a pressure sensor connected to the body-worn harness is above a threshold pressure value. In response to detecting the predefined physical configuration, the electronic reading device is activated. Upon being activated, the electronic reading device is configured to receive a signal from the signal-emitting device, the signal containing data pertaining to a physical object associated with the signal-emitting device.
Description
- The present application is a division application of U.S. patent Ser. No. 11/422,002, filed on Jun. 2, 2006 which claims the benefit under 35 U.S.C. §119(e) to provisional application No. 60/689,637, filed Jun. 10, 2005, the entire contents of which are incorporated herein by reference.
- In modern corporations with large distribution systems, managing products in the distribution system is typically a complex endeavor. Where corporations distribute a reusable product, collection and reprocessing of that product may further add complexity to what may be an already complex system. Keeping track of the products within a distribution system typically requires efficient data collecting and record keeping and an efficient way of storing such information.
- Some corporations utilize various technologies to improve product management in large distribution systems. For example, some corporations may use barcodes and other corporations may use machine readable tags such as Radio Frequency Identification (RFID) tags to track products in their distribution system. RFID tags may be wirelessly read when the RFID tag is brought into proximity with an RFID reader. Wirelessly reading RFID tags may allow information about the tagged product to be quickly obtained and processed.
- There are generally less constraints upon reading a RFID tag than reading a barcode (e.g., direct line of sight between the barcode and the barcode reader), therefore using RFID tags in a situation where barcodes would suffice may save time. But, in some cases, wirelessly reading RFID tags may still be a time consuming process. For example, in situations where large numbers of products are being scanned, a worker may individually locate and scan the RFID tag on each product. The repetitive nature of this process may cause significant delays while each RFID tag is scanned and may be subject to human error (e.g., if the worker forgets to turn the RFID reader on, or if the worker accidentally omits scanning one or more items).
- Accordingly, what is needed is an improved method and apparatus for wirelessly reading machine readable tags.
- The present invention generally provides methods and systems for reading information from a signal-emitting device, such as a wireless identification tag. In one embodiment, the method includes providing an electronic reading device mounted to a body-worn harness adapted to be worn on a body of a user. The method further includes detecting a predefined physical configuration assumed by at least a portion of the body by determining that a pressure value measured via a pressure sensor connected to the body-worn harness is above a threshold pressure value. In response to detecting the predefined physical configuration, the electronic reading device is activated. Upon being activated, the electronic reading device is configured to receive a signal from the signal-emitting device, the signal containing data pertaining to a physical object associated with the signal-emitting device.
- In one embodiment, a method for reading a wireless identification tag may include measuring a pressure value via a pressure sensor connected to a hand-mounted device. If the pressure value measured via the pressure sensor is above a threshold pressure value, then the method may also include wirelessly reading tag data from the wireless identification tag via an antenna connected to the hand-mounted device.
- In one embodiment, a tangible computer-readable medium containing a program product may be provided. When executed by a processor, the program product may perform an operation which may include measuring a pressure value via a pressure sensor connected to a hand-mounted device. If the pressure value measured via the pressure sensor is above a threshold pressure value, then the operation may also include wirelessly reading tag data from the wireless identification tag via an antenna connected to the hand-mounted device.
- In one embodiment, a device may include a hand-mounted device with an antenna, a pressure sensor connected to the hand-mounted device, and circuitry. The circuitry may be configured to perform an operation which may include measuring a pressure value via the pressure sensor connected to the hand-mounted device. If the pressure value measured via the pressure sensor is above a threshold pressure value, then the operation may also include wirelessly reading tag data from the wireless identification tag via an antenna connected to the hand-mounted device.

- In one embodiment of the invention, the
system 100 may include a wireless identification tag reader/writer module 108 attached to or embedded, for example, in aglove 102 or other wearable item. In one embodiment, theglove 102 or other wearable item may also include one ormore pressure sensors 104, and/or anantenna 106 for communication with awireless identification tag 120. The reader/writer module 108 may be configured to read wireless identification tag data from thewireless identification tag 120 located on a product, such as agas cylinder 122 or a rack ofgas cylinders 130, as depicted inFIG. 1 . - In one embodiment, a wireless identification tag reader/
writer 116 may also be used to read wireless identification tag data via anantenna 114 built into anozzle 118 used when filling agas cylinder 122. The wireless identification tag reader/writer 116 andantenna 114 and/or the reader/writer module 108 attached to theglove 102 may also be used to write information to thewireless identification tag 120 such as the gas cylinder fill date, gas quality, gas type, and gas cylinder test date. - The
system 100 may transmit the wireless identification tag data read by the reader/writer module 108 to aportable computing device 110. The wireless identification tag data may, for example, be transmitted via a wireless or a wired connection. Theportable computing device 110 may include a mobile phone, a tablet computer, or a personal digital assistant (PDA). As depicted, theportable computing device 110 may be worn by theuser 112 of theglove 102. As will be described further in relation toFIGS. 8 and 9 , auser 112 of theportable computing device 110 may enter additional information corresponding to thewireless identification tag 120 for thegas cylinder 122 into theportable computing device 110. - The
portable computing device 110 may be configured to transmit the received wireless identification tag data and any additional information entered by theuser 112 to acentral database server 128,workstation computer 126, or another type of computing device. For example, awireless interface 132 may be used to transmit the wireless identification tag data as well as the additional information input by the user to thenetwork 170 via a wireless communication protocol, such as IEEE 802.11, Global System for Mobile Communications (GSM), or Bluetooth. Alternatively, the connection may be wired. Once on thenetwork 170, the wireless identification tag data and the additional information may be transferred acentral database server 128. - In one embodiment, processing in the
central database server 128 may be performed by aprocessing unit 134. Theprocessing unit 134 may process programs in amemory 142 including aproduct management application 148 and anoperating system 144 for thecentral database server 128. Theprocessing unit 134 may also processdata 146 and other programs or information. Such data and programs may also be stored in astorage device 138 such as a hard drive or other computer-readable medium (e.g., a compact disc or read-only memory). Thecentral database server 128 may utilize an input/output interface 136 to request and/or receive data from thenetwork 170 via anetwork link 166. Internal components of thecentral database server 128 may communicate via adata bus 138. - A
workstation 126 may be used to access thecentral database server 128 over thenetwork 170 and view the information about thegas cylinder 122 sent from theportable computing device 110 to thecentral database server 128. In one embodiment, processing in theworkstation computer 126 may be performed by aprocessing unit 150. Theprocessing unit 150 may process programs in amemory 156 including aproduct management application 162 and anoperating system 158 for theworkstation computer 126. Theprocessing unit 150 may also processdata 160 and other programs or information. Such data and programs may also be stored in astorage device 152 such as a hard drive or other computer-readable medium (e.g., a compact disc or read-only memory). Theworkstation computer 126 may utilize an input/output interface 152 to request and/or receive data from thenetwork 170 via anetwork link 168.

FIG. 2A is a block diagram which illustrates a back side (e.g., viewed from a back of a hand) of theglove 200 for wirelessly reading awireless identification tag 120 according to one embodiment of the invention, andFIG. 2B is a block diagram which illustrates a front side (e.g., viewed from a palm of the hand) of theglove 224 for wirelessly reading awireless identification tag 120 according to one embodiment of the invention. As described above, theglove 102 may include one ormore pressure sensors 104, anantenna 106 for communicating with thewireless identification tag 120, and a reader/writer module 108. - Furthermore, the reader/
writer module 108 may also contain abattery 212, apower port 206 for charging thebattery 212, reader/writermodule control circuitry 214, and aswitch 202 for setting theglove 102 to off, to automatic read, or to manual read. Theglove 102 may have asensor 222 for determining whether or not a hand is in theglove 102. Theswitch 202 and thehand sensor 222 may be connected to the reader/writer module 108 viaconnection wires 210. - In one embodiment, the
glove 102 may be a work glove, such as a safety glove which may be used for safety in a given industry. For example, theglove 102 may be insulating so that its wearer's hand is protected from extreme temperatures, may have no fingertips so that its wearer may feel the texture of an object while wearing the glove, or may be a lightweight glove completely covering the hand used when moving products at a distribution center. - In one embodiment, the reader/
writer module 108 may be located on the back side of theglove 102. The reader/writer module 108 may be configured to measure a pressure value from thepressure sensor 104, control the reading operation of the reader/writermodule control circuitry 214 usingantenna 106, and transmit the information read from thewireless identification tag 120 to aportable computing device 110 via atransceiver 204 that may use wired or wireless communication. - In one embodiment, the reader/
writer module 108 on or in theglove 102 may be used to read data from a tag when a product is grasped or handled with theglove 102. For example, thepressure sensor 104 may be used to determine when a handle on a product is being grasped. - In one embodiment, the
pressure sensor 104 may be a pressure sensor capable of measuring a range of pressures, e.g., a piezoelectric sensor. The reader/writermodule control circuitry 214 may obtain from the pressure sensor 104 a measured pressure value. In one embodiment, the reader/writermodule control circuitry 214 may activate theantenna 106 to read awireless identification tag 120 when the measured pressure value is above a threshold pressure value. (For example, a pressure value which may indicate that a product is being grasped.) By activating theantenna 106 when a product is being grasped, battery life of thebattery 212 may be conserved because thepressure sensor 104 may be used to regulate the activation of theantenna 106 so that it is not continually active. - Furthermore, by placing the
wireless identification tag 120 in a position on a product where the product is likely to be grasped, and by activating theantenna 106 when the product is grasped, the reader/writer module 108 may have an improved opportunity to successfully read thewireless identification tag 120 during a read or write operation. - In another embodiment, the
pressure sensor 104 may be a pressure sensor that detects only whether or not it is being pressed, e.g., a pushbutton. This may enable the reader/writermodule control circuitry 214 to determine whether or not there is a pressure on thepressure sensor 104. Thus, in one embodiment, the reader/writermodule control circuitry 214 may activate theantenna 106 to read awireless identification tag 120 only when there is a pressure on the pressure sensor, which in turn may aid in conservation of battery life of thebattery 212 of the reader/writer module 108, as described above. - In one embodiment, the
pressure sensor 104 may be located at the ends of one ormore fingers 216 and/or the thumb 218 (collectively the digits), and/or in thepalm 220 of theglove 102. This configuration may be beneficial in product management because it may allow for reading of thewireless identification tag 120 only when a predefined body configuration, like grasping or lifting, is detected as a pressure on thepressure sensor 104. Optionally, thepressure sensor 104 may be located anywhere else on theuser 112. Thepressure sensor 104 may be connected to the reader/writer module 108 viaconnection wires 210. In one embodiment, theconnection wires 210 may include a twisted pair of wires to reduce induction between the wires. - In one embodiment, the
antenna 106 may be located between a first andsecond finger 216 of theglove 102. In one embodiment, theantenna 106 may be a directional antenna. By placing theantenna 106 between a first andsecond finger 216 of theglove 102, the antenna may be positioned to measure thewireless identification tag 120 when it is in close proximity to a hand of auser 112. This configuration may be beneficial in product management because it may allow for seamless reading of thewireless identification tag 120 when theuser 112 handles a product as described above. Optionally, theantenna 106 may be located anywhere else on theuser 112. For example, theantenna 106 may be connected to the reader/writer module 108 via aconnection 208. In one embodiment, theconnection 208 may include a twisted pair of wires to reduce induction between the wires. - In one embodiment, the
switch 202 may be used to select one three operating modes of the reader/writer module 108. If the switch is in the off position, the reader/writer module 108 is off, no pressure is being detected, and no read operation may be performed. If the switch is in the manual position, the reader/writer module 108 may be activated, and read operations may be continually occurring regardless of detection of pressure by thepressure sensor 104. If the switch is in the automatic position, the reader/writer module 108 may be activated, detection of pressure by thepressure sensor 104 may take place, and read operations may occur if thepressure sensor 104 detects a pressure on the sensor. - In one embodiment, the reader/
writer module 108 may provide auditory feedback to theuser 112 when wireless identification tag data is received. For example, the auditory feedback may be a short tone signifying a successful read of awireless identification tag 120, or may be speech identifying the read operation and details about thewireless identification tag 120. Such feedback may enable theuser 112 to more quickly identify misreads and correct errors as they occur. - As described above, the
glove 102 may include asensor 222 which may be used to detect the hand of the user 102 (e.g., to detect when the glove is being worn). In one embodiment, thesensor 222 may work in conjunction with theswitch 202. For example, in one embodiment, the reader/writer module 108 may only be used for reading or writing when thesensor 222 detects that there is a hand in theglove 102 and when theswitch 202 is not in the off position. As described above, such reading and writing may further depend on whether thepressure sensor 104 detects a pressure. - In another embodiment, the
sensor 222 may replace the function of the off position of theswitch 202. For example, theswitch 202 may have two positions: automatic read and manual read. When a user's hand is detected in theglove 102 bysensor 222, the reader/writer module 108 may be automatically activated. When the reader/writer module 108 is activated, the reader/writermodule control circuitry 214 may automatically monitor the pressure sensor to determine whether to activate theantenna 106 as described below. - In another embodiment, the
sensor 222 may replace theswitch 202. For example, when a user's hand is detected in theglove 102 bysensor 222, the reader/writer module 108 may be automatically activated. When the reader/writer module 108 is activated, the reader/writermodule control circuitry 214 may automatically monitor the pressure sensor to determine whether to activate theantenna 106 as described below. - While
FIGS. 2A and 2B illustrate the reader/writer module 108, theantenna 106, and thepressure sensors 104, on the outside of theglove 102, alternate embodiments may provide one or more of thecomponents FIG. 3 is a block diagram which illustrates a cross-section of theglove 102 according to one embodiment of the invention. Theglove 102 may have anouter layer 302, aconductive layer 304, and aninner layer 306. In one embodiment, theconductive layer 304 may include pieces of conductive fabric, wires, or a ribbon cable which may be used to provide power to components of theglove 102 and transmit data and/or signals to and from components of theglove 102. Thepressure sensors 104, the reader/writer module 108, and/or theantenna 106, may be embedded within theconductive layer 304. Although one embodiment of the glove layers 302, 304, 306 is depicted, one skilled in the art should recognize that there are various ways of constructing theglove 102, including using multiple layers of conductive fabric in theglove 102 instead of or in addition to wires or a single layer of conductive fabric. -
FIG. 4 is a block diagram which illustrates agas cylinder 122 tagged with a wirelessly readableelectronic tag 120 according to one embodiment of the invention, andFIG. 5 is a block diagram which illustrates agas cylinder 122 with acap 124 tagged with a wirelessly readableelectronic tag 120 and agas cylinder 122 with a removedcap 124 according to one embodiment of the invention. - In
FIG. 4 ,wireless identification tags 120 are depicted on thegas cylinder handle 402 and on thegas cylinder valve 404 that controls the flow of gas out of thegas cylinder 122 through thegas cylinder pipe 406. Optionally, as depicted inFIG. 5 , thewireless identification tag 120 may be placed on thehandle 504 of thegas cylinder cap 124. By placing thewireless identification tag 120 on or near thehandle 504 of the gas cylinder top or on or near thegas cylinder handle 402, thewireless identification tag 120 may be positioned so that the reader/writer module 108 in theglove 102 may read thewireless identification tag 120 when thepressure sensor 104 detects a pressure due to theuser 112 grasping either thehandle 504 of the gas cylinder cap or thegas cylinder handle 402. - As depicted in
FIG. 5 , a wireless identification tag reader/writer 116 may also be used to read wireless identification tag data via anantenna 114 built into anozzle 118 used when filling agas cylinder 122. As described above, the wireless identification tag reader/writer 116 andantenna 114 may also be used to write information to thewireless identification tag 120 such as the gas cylinder product identification number, gas cylinder fill date, gas quality, gas type, and gas cylinder test date. The wireless identification tag reader/writer 116 may be battery powered, or may be wired 502 to a power source. The wireless identification tag reader/writer 116 may communicate with thecentral database server 128 through thewireless interface 132, or may be wired directly into thenetwork 170. - In one embodiment, a
wireless identification tag 120 may also be placed on arack 130 for holding gas cylinders to provide further automation while tracking product shipments with the reader/writer module 108 in theglove 102. For example, when auser 112 opens a door on therack 130, theportable computing device 110, or other computer system, may recognize that thewireless identification tag 120 read was on arack 130. Consequently, theportable computing device 110 may associate allgas cylinders 122 corresponding to subsequentwireless identification tags 120 with therack 130. This association may continue until theuser 112 closes the door on therack 130, and thewireless identification tag 120 corresponding to therack 130 is again read by the reader/writer module 108 in the user'sglove 102. - In one embodiment, when the
user 112 of theglove 102 moves therack 130 ofgas cylinders 122, the reader/writer module 108 may detect therack 130. Theuser 112 may update information about therack 130 in theportable computing device 110, which in turn may cause the information about thegas cylinders 122 on therack 130 to be updated. Such information about therack 130 andcylinders 122 may include location, date of delivery, and customer identification. - In
FIGS. 4 and 5 , possible locations forwireless identification tag 120 placement are shown. However, one skilled in the art will recognize that wireless identification tags may be placed anywhere on thegas cylinder 122 or any other product tagged by awireless identification tag 120. -
FIG. 6A is a flow diagram depicting aprocess 600 for reading awireless identification tag 120 using aswitch 202 and apressure sensor 104 according to one embodiment of the invention. Theprocess 600 may begin atstep 602 where the reader/writer module 108 determines if theswitch 202 is in the off position. If theswitch 202 is not in the off position, theprocess 600 proceeds to step 604. - In
step 604 the reader/writer module 108 checks to see iffunction switch 202 is in its manual position. If theswitch 202 is set to manual, theprocess 600 skips to step 608. Ifswitch 202 is set to automatic, theprocess 600 proceeds to step 606. - In
step 606 the reader/writer module 108 checks to see if a pressure value measured by thepressure sensor 104 is above a threshold pressure value. If the measured pressure value is greater than the threshold pressure value, theprocess 600 proceeds to step 608 where the reader/writermodule control circuitry 214 on the reader/writer module 108 is activated by turning theantenna 106 on for a set period of time to read awireless identification tag 120. If the pressure value measured by thepressure sensor 104 is not greater than a threshold pressure value, theprocess 600 returns to step 602. - In
step 610, a determination is made whether valid wireless identification tag data was read. For example, the validity of the data may be established by any of various methods, including determining a checksum value from the wireless tag data, or requiring redundant reading of the same information. If the data is not valid, or if no tag is present, theprocess 600 returns to step 606. If the wireless identification tag data is valid, theprocess 600 proceeds to step 612, where the reader/writer module 108 sends the wireless identification tag data to theportable computing device 110 via thetransceiver 204. Theprocess 600 may then repeat, returning to step 602. -
FIG. 6B depicts analternate process 650 for reading awireless identification tag 120 using aswitch 202, asensor 222, and apressure sensor 104 according to one embodiment of the invention. Theprocess 650 may begin atstep 652 where the reader/writer module 108 determines from thesensor 222 if a hand of auser 112 is in theglove 102. When the hand of theuser 112 is in theglove 102, theprocess 650 may proceed to step 654. - In
step 654 the reader/writer module 108 checks to see iffunction switch 202 is in its manual position. If theswitch 202 is set to manual, theprocess 650 skips to step 658. Ifswitch 202 is set to automatic, theprocess 650 proceeds to step 656. - In
step 656 the reader/writer module 108 checks to see if a pressure value measured by thepressure sensor 104 is above a threshold pressure value. If the measured pressure value is greater than the threshold pressure value, theprocess 650 proceeds to step 658 where the reader/writermodule control circuitry 214 on the reader/writer module 108 is activated by turning theantenna 106 on for a set period of time to read awireless identification tag 120. If the pressure value measured by thepressure sensor 104 is not greater than a threshold pressure value, theprocess 650 returns to step 652. - In
step 660, a determination is made whether valid wireless identification tag data was read. For example, the validity of the data may be established by any of various methods, as described above. If the data is not valid, or if no tag is present, theprocess 650 returns to step 656. If the wireless identification tag data is valid, theprocess 650 proceeds to step 662, where the reader/writer module 108 sends the wireless identification tag data to theportable computing device 110 via thetransceiver 204. Theprocess 650 may then repeat, returning to step 652. - One skilled in the art should in the art should recognize that the processes described above are merely exemplary and that there are various alternate ways of implementing the
processes FIGS. 6A and 6B . -
FIG. 7 is a flow diagram depicting a process 700 for processing the data associated with theglove 102 for wirelessly reading thewireless identification tag 120 according to one embodiment of the invention. The process 700 may begin atstep 702, where wireless identification tag data for a product is obtained with a reader/writer module 108 in or on aglove 102, and the wireless identification tag data is sent to aportable computing device 110. Step 702 may include performance of the steps described above with respect to process 600 inFIG. 6A orprocess 650 inFIG. 6B . - In
step 704, a user of theportable computing device 110 may edit and add data to a list ofwireless identification tags 120 recognized by the reader/writermodule control circuitry 214 in theglove 102 and enter item specific information corresponding to the data from the wireless identification tags 120. Theportable computing device 110 may send the user updated information and wireless identification tag data from theportable computing device 110 to acentral database server 128 via anetwork 170 instep 706. - In
step 708, thecentral database server 128 may use aproduct management application 148 to process the new information and updatedata 146 in a server database accordingly. Instep 710, theproduct management application 148 on thecentral database server 128 may determine relevant information about the product corresponding to the data from thewireless identification tag 120 and may send that information to theportable computing device 110 via thenetwork 170. For example, if the product were thegas cylinder 122, relevant information retrieved from thecentral database server 128 and sent to thepersonal computing device 110 may include the date of the next scheduled gas cylinder safety test, the type of gas in thegas cylinder 122, and any safety and handling information associated with thegas cylinder 122. - In
step 712, the data on theportable computing device 110 for the product corresponding to thewireless identification tag 120 may be updated with the relevant information from the database on thecentral database server 128 and may display such relevant information. - In one embodiment, the relevant information may cause the
portable computing device 110 to alert theuser 112 to further actions required by theuser 112 on the product. Such actions may include placing theglove 102 over thewireless identification tag 120 so that the new and relevant information may be written to thewireless identification tag 120 from the reader/writer module 108. Other actions may include removing the product from circulation, taking the product in for testing, and loading the product onto aspecific rack 130. - One skilled in the art should recognize that there are various ways to transfer and manipulate the wireless tag data read by the reader/
writer module 108 in theglove 102, and that any embodiments provided above are merely illustrative. - As described above, the reader/
writer module 108 may be used to transmit wireless identification tag data to theportable computing device 110.

During the pause in reader/writermodule control circuitry 214 activity, the reader/writer module 108 may send the data obtained from a plurality of successful read operations ofwireless identification tags 120 to theportable computing device 110 via thetransceiver 204. - Optionally, the reader/
writer module 108 may not be in continual communication with theportable computing device 110. Therefore, the reader/writer module 108 may store wireless identification tag data until a direct connection to theportable computing device 110, wired or wireless, can be made. Examples of the connection include connection by a universal serial bus (USB) cable, infrared signal via infrared ports, or Bluetooth. -
FIG. 8 is a block diagram which illustrates aportable computing device 110 according to one embodiment of the invention. Processing in theportable computing device 110 may be performed by aprocessing unit 806. Theprocessing unit 806 may process programs in amemory 816 including aproduct management application 820, anetwork resources application 822, and anoperating system 824 for theportable computing device 110. Theprocessing unit 806 may also processdata 818 and other programs or information. Such data and programs may also be stored in astorage device 810 such as a hard drive or other computer-readable medium (e.g., a compact disc or read-only memory). - The
portable computing device 110 may utilize an input/output interface 808 to receive input from theuser 112. Theportable computing device 110 may utilize anetwork interface 812 to request and/or receive data from thenetwork 170 via anetwork link 802. Similarly, theportable computing device 110 may utilize acontrol module interface 814 to request and/or receive data from thetransceiver 204 of reader/writer module 108 on theglove 102 via alocal link 804. Thelocal link 804 may communicate withtransceiver 204 via a wireless protocol, like Bluetooth, IEEE 802.11, or infrared technologies. Alternatively, thelocal link 804 may communicate withtransceiver 204 via a wired connection. Internal components of theportable computing device 110 may communicate via adata bus 826. -
FIG. 9 is a block diagram which illustrates a graphical user interface (GUI) 902 of theportable computing device 110 according to one embodiment of the invention. Theportable computing device 110 may havebuttons 904 and/or atouch screen 906 so that theuser 112 of the reader/writer module 108 on theglove 102 may enter additional information about the product associated with thewireless identification tag 120 read by the reader/writer module 108 on theglove 102 as described above. - In one embodiment, such additional information may include the type of product tagged by the
wireless identification tag 120, the action performed on the product, and/or the location where the product was read by theuser 112 with theglove 102. In another embodiment, theportable computing device 110 may automatically add additional information about the product associated with thewireless identification tag 120 read by theuser 112 with theglove 102. Such information could include coordinate data from the Global Positioning System (GPS), the time thewireless identification tag 120 was read by the reader/writer module 108, and/or identification of theuser 112 of theglove 102. - This additional information may be entered by using a
GUI 902 on theportable computing device 110. In one embodiment of the invention, theGUI 902 contains a table with several fields, including tags read by the wirelessidentification tag reader 908, type of product scanned by the wirelessidentification tag reader 910, and action performed on theproduct 912. Theuser 112 may use theportable computing device 110 to send wireless identification tag data and any additional information to thecentral database server 128. However, if theuser 112 tries to send this data before entering all the required information, anotice 914 may appear to inform theuser 112 of the missing information. Thenotice 914 may describe themissing information 916, may indicate the wireless identification tag that is missing requireddata 918, may provide fields for updating themissing information screen buttons additional tag data 922 or leaving therecord blank 920. - In one embodiment, the
portable computing device 110 may provide auditory feedback to theuser 112 when wireless identification tag data is received. For example, the auditory feedback may be a short tone signifying a successful read of awireless identification tag 120, or may be speech identifying the read operation and details about thewireless identification tag 120. Such feedback may enable theuser 112 to more quickly identify misreads and correct errors as they occur. In some cases, the auditory feedback may be provided via a speaker embedded in theportable computing device 110. Optionally, the auditory feedback may be provided via other means, such as headphones attached to theportable computing device 110. - One skilled in the art will recognize that the
portable computing device 110 andGUI 902 ofFIG. 9 are only examples, and may be configured in any appropriate manner. For example, in some cases theportable computing device 110 may be configured to transmit wireless information tag data via thetransceiver 204 to thecentral database server 128 without user interaction. - As was described above in reference to
FIG. 7 ,step 706, the portable computing device may send wireless identification tag data read by the reader/writer module 108 and the additional information entered by theuser 112 of theportable computing device 110 to acentral database server 128. Thecentral database server 128 may include a database such as, for example, thedatabase 1002 depicted inFIG. 10 . - The
database 1002 contains information that may be stored for a wirelessly readable electronic tag according to one embodiment of the invention. The information may be stored on thecentral database server 128 and/or written to thewireless identification tag 120. The data may includes a wirelesstag identification number 1004, gascylinder identification number 1006, date the gas cylinder was refilled 1008, type of gas in thegas cylinder 1010, quality of gas in thegas cylinder 1012, date the gas cylinder was tested 1014, andadditional information 1016 input by the user of the reader/writermodule control circuitry 214 on theglove 102 after scanning the gas cylinder with the reader/writermodule control circuitry 214. - In one embodiment, the
database 1002 may include information on the physical location of thewireless identification tag 120 when it was read by the reader/writermodule control circuitry 214. The physical location may be obtained in many ways. For example, theportable computing device 110 or the reader/writer module 108 on theglove 102 may use GPS or triangulation to determine the exact location where a wireless identification tag was read. Such data may be recorded by theportable computing device 110 and transmitted, along with the wireless identification tag data, to thecentral database server 128. Also, location may be obtained from knowing the location of thewireless interface 132 used by theportable computing device 110 to send wireless identification tag data to thenetwork 170. Location data can be any of various location representation forms including latitude and longitude coordinates, address information, and/or the name of a facility where awireless identification tag 120 was read by the reader/writer module 108 in theglove 102. - For example, the
user 112 may read wireless identification tag data with the reader/writer module 108 in theglove 102 that may be subsequently transmitted wirelessly from the reader/writer module 108 to the awireless interface 132. Since thewireless interface 132 may be known to be in a certain location, the relative location of thewireless identification tag 120 may be obtained from the corresponding known location of thewireless interface 132. Furthermore, theportable computing device 110, thecentral database server 128, or theworkstation 126 may be capable of determining a correlation between types of location data. For example, from latitude and longitude coordinate data, a corresponding address of the tagged product may be obtained. - In one embodiment, the reader/
writer module 108 in theglove 102 may also be used to track the productivity of theuser 112. For example, thedatabase 1002 may maintain information on the user of the reader/writer module 108 in theglove 102, including a total usage time of the reader/writer module 108 by theuser 112, a total number of wireless identification tags read by the reader/writer module 108 while under control of theuser 112, or any other data that may be useful in determining the productivity of theuser 112. - To relate user productivity to a
specific user 112, the identity of theuser 112 may be recorded. In one embodiment, the user's identity may be determined from login information on theportable computing device 110. For example, when the user places theglove 102 on a hand, thesensor 222 may detect the presence of the hand, causing the reader/writer module 108 to send a message to theportable computing device 110. Theportable computing device 110 may use the message from the reader/writer module 108 to initiate a request to the user for login information. Optionally, the identity of auser 112 may be determined by reading a fingerprint of theuser 112, reading an identification card of theuser 112, and/or reading a wireless identification tag belonging to theuser 112. - In another embodiment, the reader/
writer module 108 in theglove 102 may have a unique identification number that may be known to be associated with asingle user 112. When awireless identification tag 120 is read by the reader/writer module 108 in theglove 102, theportable computing device 110 or thecentral database server 128 may correlate the identification number of the reader/writer module 108 with theuser 112 of theglove 102 according to the known association. - Similarly, the
portable computing device 110 may have a unique identification number that may be known to be associated with asingle user 112. When theportable computing device 110 transmits the wireless identification tag data to thecentral database server 128, thecentral database server 128 may correlate the identification number of theportable computing device 110 with the identification of theuser 112 according to the known association. - One skilled in the art will recognize that the identification techniques described above are merely representative, and do not encompass the numerous ways to identify a
user 112. - To further clarify how the present invention may be used to improve tracking of products in a product management system, the following example of a
gas cylinder 122 management system is presented. - In one embodiment, when a
gas cylinder 122 is filled at a gas cylinder filling station, the filling station may have a wireless identification tag reader/writer 116 and its associatedantenna 114 built into the fillingnozzle 118. While thegas cylinder 122 is being filled, the wireless identification tag reader/writer 116 may read thewireless identification tag 120 on thegas cylinder 122. The wireless identification tag reader/writer 116 may transmit the wireless identification tag data to acentral database server 128 that may process the wireless identification tag data and return updated data to the wireless identification tag reader/writer 116. - In one embodiment, the wireless identification tag reader/
writer 116 may write this updated data to thewireless identification tag 120 on thegas cylinder 122. The updated information may include, but is not limited to, the type of gas in thegas cylinder 122, the date thegas cylinder 122 was filled, the amount of gas in thegas cylinder 122, and the location of thegas cylinder 122 when filled. - Before beginning work, a
user 112 may put on a pair of gloves (for example, as may be required by standard safety procedures). If one of those gloves is theglove 102 as described above,sensor 222 in theglove 102 may sense that theuser 112 is wearing the glove and may activate the reader/writer module 108. - In one embodiment, once the
gas cylinder 122 has been filled, auser 112 may remove thegas cylinder 122 from the filling station. When theuser 112 moves thegas cylinder 122, apressure sensor 104 in theglove 102 of the user may measure a pressure value of a pressure exerted on theglove 102. The wireless identification tag reader/writer module 108 in theglove 102 may determine that the measured pressure value is greater than a threshold pressure value, and consequently activate anantenna 106 in theglove 102 for wireless communication with thewireless identification tag 120. - In one embodiment, if the reader/
writer module 108 successfully reads wireless identification tag data from thewireless identification tag 120, the wireless identification tag data is subsequently sent to aportable computing device 110 worn by theuser 122, as described above. Theportable computing device 110 may allow theuser 112 to enter additional information about thegas cylinder 122 tagged by thewireless identification tag 120 read by the reader/writer module 108. - In one embodiment, the wireless identification tag data as well as any additional information entered by the
user 112 may be transmitted from theportable computing device 110 to thecentral database server 128. Thecentral database server 128 may process the wireless identification tag data as well as any additional information entered by theuser 112 and return updated data toportable computing device 110. The updated information may include, but is not limited to, type of gas in thegas cylinder 122, date thegas cylinder 122 was last filled, amount of gas in thegas cylinder 122, action to be performed on thegas cylinder 122, and location of thegas cylinder 122. - The
portable computing device 110 may respond to the updated data in a number of ways, including notifying theuser 112 that the gas cylinder should 122 be placed on a particulargas cylinder rack 130 for delivery of the filledgas cylinder 122 to a customer. Additionally, theportable computing device 110 may provide a map and address to the delivery location. - In one embodiment, the
wireless identification tag 120 may be placed on agas cylinder rack 130. When theuser 112 opens a door on therack 130, theportable computing device 110 may recognize that thewireless identification tag 120 read by the reader/writer module 108 was located on therack 130. Consequently, theportable computing device 110 may associate allgas cylinders 122 corresponding to subsequentwireless identification tags 120 with therack 130. This association may continue until theuser 112 closes the door on therack 130, and thewireless identification tag 120 corresponding to therack 130 is again read by the reader/writer module 108 in the user'sglove 102. - In one embodiment, when the
user 112 delivers thegas cylinder 122 to the customer, a process may occur similar to when theuser 112 removed thegas cylinder 122 from the filling station. For example, theuser 112 of the reader/writer module 108 in theglove 102 may enter additional information into theportable computing device 110 identifying that thegas cylinder 122 is being delivered to the customer. Theportable computing device 110 may have a built in GPS receiver that determines the customer's location (e.g., latitude and longitude coordinates), and sends that location information, along with the wireless identification tag data and any additional information added by theuser 112 of theportable computing device 110, to thecentral database server 128. In this manner, not only may a record of products on thecentral database server 128 be seamlessly updated, but accurate tracking of the location of a product may also be maintained. - In one embodiment, once the customer has used all the gas in the
gas cylinder 122, theuser 112 may travel to the customer's location to retrieve thegas cylinder 122. When the user moves thegas cylinder 122, a process may occur similar to when theuser 112 removed thegas cylinder 122 from the filling station. Upon retrieving thecylinder 122 and reading thewireless identification tag 120 as described above, theuser 112 of the reader/writer module 108 in theglove 102 may enter additional information into theportable computing device 110 identifying that thegas cylinder 122 is being retrieved from the customer. - In one embodiment, the
portable computing device 110 sends this additional user entered information, along with the wireless identification tag data from thewireless identification tag 120 on thegas cylinder 122, to thecentral database server 128. An application running on thecentral database server 128 may recognize that the customer needs anew gas cylinder 122, and may automatically re-order agas cylinder 122 for the customer. - In one embodiment, the
user 112 may return thegas cylinder 112 to the filling station, and the sequence described above may begin again. - One skilled in the art will recognize that the preceding example is only a representation of one way the wireless tag reader/
writer module 108 in aglove 102 may be used to improve the tracking of products in a product management system. - Embodiments of the present invention are described above with respect to a reader/
writer module 108 in or on aglove 102 worn on the hand of auser 112. However, embodiments of the present invention are not limited to this or other glove-based embodiments. For example, theantenna 106 may be attached to a ring worn by theuser 112, thepressure sensor 104 may be placed in a shoe worn by theuser 112, and/or the reader/writer module 108 may be worn on a belt of theuser 112. - Furthermore, the reader/
writer module 108 in or on theglove 102 and theportable computing device 110 have been described above as separate entities. However, embodiments of the present invention are not limited to this configuration. The reader/writer module 108 and theportable computing device 110 may be a single entity, capable of wirelessly reading awireless identification tag 120 and accepting additional information about the product associated with thewireless identification tag 102 from theuser 112. - Processes and apparatus for practicing the present invention have been described. It will be understood and readily apparent to the skilled artisan that many changes and modifications may be made to the above-described embodiments without departing from the spirit and the scope of the present invention. The foregoing is illustrative only and that other embodiments of the integrated processes and apparatus may be employed without departing from the true scope of the invention defined in the following claims.
