The person monitoring system 100 (hereinafter invention) is a proximity surveillance apparatus. The invention 100 comprises an interrogator 101, a tag 102, and an accessory 103. A communication link 104 is established between the interrogator 101 and the tag 102 at predetermined, but not necessarily regular, intervals to ensure that the tag 102 is in the proximity of the interrogator 101. The tag 102 attaches to an accessory 103. The invention 100 is adapted for use with a first person 141 and a second person 142. The first person 141 carries the interrogator 101. The second person 142 wears the accessory 103 with the tag 102. Should the communication link 104 fail to be established, the interrogator 101 initiates an alarm informing the first person 141 that the second person 142 is no longer nearby.
The communication link 104 further comprises an interrogation signal 105 and a reflected signal 106.
The interrogator 101 comprises a personal data device 111 that is configured to transmit an interrogation signal 105 at a previously specified radio frequency. The personal data device 111 is further configured to receive the reflected signal 106 as a radio frequency signal. The transmission of the interrogation signal 105 and the receipt of the reflected signal 106 is supervised by an application 112.
The application 112 is a logical mechanism that is incorporated into the personal data device 111 that: 1) initiates the transmission of the interrogation signal 105 at predetermined intervals; 2) confirms the receipt of the reflected signal 106; and, 3) should the receipt of the reflected signal 106 not be confirmed the application 112 generates an alarm through the personal data device 111.
The personal data device 111 further comprises a near field communication functionality 113. The near field communication functionality 113: 1) physically generates the interrogation signal 105; and, receives and processes the reflected signal 106 for the application 112. The personal data devices incorporating the near field communication functionality 113 described in this paragraph are readily and commercially availability.
The tag 102 comprises a commercially available RFID tag 121 which are also commonly referred to as a token. The tag 102 is an active RFID tag 121 using technology similar to the technology used for the automatic collection of road tolls. The RFID tag 121 is powered by a battery 122 that is connected the RFID tag 121. The RFID tag 121 technology described in this paragraph is well known and documented in the electrical arts.
The theory of operation of the interrogator 101 and the tag 102 is described in this paragraph. As shown in FIG. 7, the near field communication functionality 113 of the personal data device 111 generates the interrogation signal 105. The tag 102 modifies the wave form (though generally not the frequency) of the interrogation signal 105 and reflects the modified wave form back to near field communication functionality 113. The modification made to the wave form is sufficient to uniquely identify the RFID tag 121. The unique identification insures that RFID tag 121 associated with the proper second person 142 is responding to the interrogation signal 105. The purpose of using an active RFID tag 121 is to extend the range of the near field communication functionality 113. Near field communication functionality 113 is intended to operate at close range (<20 cm). By using an active RFID tag 121, this range can be extended. While, at the frequencies discussed below, existing technologies can increase the range up to 100 meters the inventor anticipates a practical effective range of approximately 10 meters for the invention 100.
In the first potential embodiment of the disclosure, the previously specified radio signal frequency is 13.56 MHz. On some personal data devices 111 it is anticipated that it may be required to supplement the near field communication functionality 113 with a power booster to increase the range of interrogation signal 105.
The accessory 103 comprises a housing 131, a fastener 134 and a textile 135. As shown most clearly in FIGS. 1, 2, and 3, the housing 131 is a rigid casing that contains the tag 102. The textile 135 is a readily and commercially available textile. The fastener 134 is a device that attaches the housing 131 to the textile 135. Suitable fasteners include, but are not limited to, snaps, buttons, pins 152, and hook and loop fasteners 151. As shown most clearly in FIGS. 1, 2, and 3, the housing 131 further comprises a capped tube 132 and a closure 133. The inner diameter of the capped tube 132 is sized to receive the RFID tag 121 and the battery 122. The closure 133 is a lid that is intended to close the open face of the capped tube 132. Tubular devices, such as flashlights, that receive and operate batteries 122 and electrical circuits are well known and documented in the electrical arts.
In the first potential embodiment of the disclosure, as shown in FIGS. 1 through 3, the fastener 134 is a hook and loop fastener 151. The first hook or loop surface 153 of the hook and loop fastener 151 is attached to the textile 135 with a sewn seam. The second hook or loop surface 154 of the hook and loop fastener 151 is attached to the capped tube 132 with an adhesive.
In a second potential embodiment of the disclosure, as shown in FIGS. 1 through 3, the fastener 134 is a pin 152.
The capped tube 132 and the closure 133 are formed from a molded plastic. The conductivity of metals will interfere with radio transmissions through the capped tube 132 and the closure 133 and is therefore not preferred in the formation of the capped tube 132 and the closure 133.
To use the invention 100, the application 112 is initiated on the personal data device 111 and carried by the first person 141 while the accessory 103 with the tag 102 is worn by the second person 142.
