Abstract
A cryptocurrency management device (CMD) may be used to perform various cryptocurrency management functions, such as storage of cryptocurrency, user authentication, and initiation or processing of a transaction for transferring cryptocurrency. To conserve the power resources of the CMD, components of the CMD may be transitioned to a sleep state for extended periods of time. Such components may be automatically activated by a user touching the CMD or bringing a wireless communication device within range of the CMD. The circuitry of the CMD that triggers the activation are capable of continuously monitoring for such inputs over extended periods of time without consuming significant amounts of power, thereby conserving the power resources of the CMD.
Claims20
A cryptocurrency management device comprising:
- an antenna for receiving a wireless signal from a mobile near field communication (NFC) device while the cryptocurrency management device is in a sleep state;
- at least one processor configured to store at least one private key for use in generating an authenticating signature for a multi-signature address of a cryptocurrency network and perform operations for managing cryptocurrency associated with the multi-signature address, including authorization of at least one transaction for transferring the cryptocurrency;
- a rectification circuit electrically coupled to the antenna and the at least one processor, wherein the rectification circuit is configured to modify at least one characteristic of the wireless signal from the antenna to convert the wireless signal into an activation signal for activating the at least one processor, wherein the rectification circuit is configured to transmit the activation signal to the at least one processor which causes the at least one processor to awaken the cryptocurrency management device from the sleep state to an awake state, wherein a power consumption by the at least one processor exceeds a threshold while the at least one processor is in the awake state, and wherein the power consumption by the at least one processor is less than the threshold by greater than zero while the at least one processor is in the sleep state;
- and
- a non-transitory computer-readable storage medium coupled to the at least one processor, wherein the at least one processor is configured to execute instructions stored in the non-transitory computer-readable storage medium while in the awake state and after receipt of the activation signal.

A cryptocurrency management device comprising:
- an antenna for receiving a wireless signal from a mobile device while the cryptocurrency management device is in a sleep state;
- at least one processor;
- a rectification circuit electrically coupled to the antenna and the at least one processor, wherein the rectification circuit is configured to receive energy of the wireless signal from the antenna and convert the energy into an activation signal for activating the at least one processor, wherein the rectification circuit is configured to transmit the activation signal to the at least one processor which causes the at least one processor to awaken the cryptocurrency management device from the sleep state to an awake state, and wherein a power consumption by the at least one processor exceeds a threshold while the at least one processor is in the awake state, and wherein the power consumption by the at least one processor is less than the threshold by greater than zero while the at least one processor is in the sleep state;
- and
- a non-transitory computer-readable storage medium coupled to the at least one processor that is configured to store an indication of receipt of the activation signal.
2 more elements
A method of waking a cryptocurrency management device, comprising:
- receiving a first signal wirelessly from a mobile near field communication (NFC) device using an antenna of the cryptocurrency management device while the cryptocurrency management device is in a sleep state;
- transmitting the first signal from the antenna to a rectification circuit that is electrically coupled to the antenna automatically in response to receiving the first signal using the antenna;
- modifying at least one characteristic of the first signal using the rectification circuit to convert the first signal into an activation signal;
- transmitting the activation signal from the rectification circuit to a processor that is electrically coupled to the antenna and the rectification circuit;
- causing the processor to awaken the cryptocurrency management device from the sleep state to an awake state responsive to the processor receiving the activation signal, wherein a power consumption by the processor exceeds a threshold while the processor is in the awake state, and wherein the power consumption by the processor is less than the threshold by greater than zero while the processor is in the sleep state;
- and
- storing, in a non-transitory computer-readable storage medium coupled to the processor, an indication of receipt of the activation signal.
