Abstract
A wireless tag includes a main body comprising an embedded wireless transducing circuit. coupled to a parallel arrangement of resistive loops embedded in respective tabs extending from the main body of the wireless tag. The wireless transducing circuit includes a globally unique identifier, a battery, a processor, a memory comprising processor-readable instructions, and a wireless communications interface; and a wake circuit configured to turn-on in response to an open circuit occurring in a respective tab. The wireless transducing circuit is configured to turn on responsive to the wake circuit receiving a voltage level above a threshold.
Claims21
A wireless tag, comprising:
- a main body comprising an embedded wireless transducing circuit coupled to a plurality of resistive loops, each resistive loop coupled at one end to a single node, wherein the single node is coupled to the embedded wireless transducing circuit such that each resistive loop is coupled in parallel to other of the resistive loops, and each resistive loop being embedded in respective tabs extending from the main body of the wireless tag, wherein the wireless transducing circuit comprises a globally unique identifier, a battery, a processor, a memory comprising processor-readable instructions, and a wireless communication interface;
- a first tab of the respective tabs connected to the main body, the first tab comprising a first portion of the plurality of resistive loops, wherein an incision in the first tab causes an open circuit in the first portion of the plurality of resistive loops;
- a wake circuit configured to turn-on in response to an open circuit occurring in the first portion of the plurality of resistive loops, wherein the wireless transducing circuit is configured to turn on responsive to the wake circuit receiving a voltage level above a first threshold voltage.
A method comprising:
- activating a wireless transducing circuit of a wireless tag, by making a first incision in a first portion of the wireless tag, the first incision creating an open circuit in a first branch of a wake circuit located in the first portion of the wireless tag,
- after the wireless transducing circuit has deactivated in response to satisfying a first criteria corresponding to a first job or journey of the wireless tag, reactivating the wireless transducing circuit of the wireless tag, by making a second incision in a second portion of the wireless tag, the second incision creating an open circuit in a second branch of the wake circuit located in the second portion of the wireless tag.
