Abstract

A system includes a transceiver for receiving a wake up signal from a wireless communication device. A processor is operatively connected to the transceiver and to a memory. The memory includes instructions recorded thereon that, when read by the processor, cause the processor to transition from a sleep mode to an active mode and power up the transceiver upon validation of the wake up signal.

Claims

1. A system comprising:

a transceiver that is passive and unpowered and that is configured for receiving an RF wake up signal from a wireless communication device and converting a received wakeup signal to DC pulses; and

a processor operatively connected to the transceiver and to a memory, wherein the memory includes instructions recorded thereon that, when executed by the processor, cause the processor to;

power up the transceiver once in an active mode

detect an interrupt by the DC pulses while in a deep sleep mode;

partially awaken to analyze the detected DC pulses to determine if the wake up signal is valid;

transition to an active mode upon validation of the wake up signal to activate and power up remaining components of the system if the wake up signal is valid; and

a second transceiver of the remaining components configured to, upon being activated and powered up;

prompt a user for an access code; and

receive an access code in response to the prompt;

wherein the processor upon execution of the instructions is further caused to;

compare the access code received in response to the prompt via at least one of the transceiver and the second transceiver to a stored value; and

the comparison, a locking mechanism to switch between locked and unlocked states.

2. The system of claim 1, wherein the processor analyzes a pulse of the wake up signal to determine if the wake up signal is valid.

3. The system of claim 1, wherein the processor allows communication between the transceiver and a mobile communication device.

4. The system of claim 1, wherein the RF wake up signal is from an RF source.

5. The system of claim 4, wherein the RF source is a smart phone.

6. The system of claim 4, further comprising an RF detector for converting the RF wake up signal to DC pulses to be evaluated with a DC processor.

7. A method for transitioning a system from a sleep mode to an active mode, comprising:

receiving an RF wake up signal from a wireless communication device at a transceiver;

converting the received RF wakeup signal to DC pulses;

detecting an interrupt by the DC pulses while in a deep sleep mode;

partially awakening to analyze the detected DC pulses to determine if the wake up signal is valid;

transitioning to an active mode upon validation of the wake up signal to activate and power up remaining components of the system if the wake up signal is valid;

return to the deep sleep mode if the wake up signal is invalid;

upon being activated and powered up, prompting by one of the remaining components a user for an access code by a component of the remaining components;

comparing an access code received in response to the prompt to a stored value; and

activating, based on a result of the comparison, a locking mechanism to switch between locked and unlocked states

waking the processor from a sleep mode upon a valid wake up signal.

8. The method of claim 7, wherein validating comprises analyzing a pulse of the wake up signal to determine if the wake up signal is valid.

9. The method of claim 7, wherein receiving comprises receiving an RF wake up signal from an RF source.

10. The method of claim 9, wherein receiving a wakeup signal includes receiving an RF wake up signal and converting the RF wake up signal to a DC pulse to be evaluated with a DC processor.

11. The method of claim 7, further comprising powering up the transceiver to communicate with a mobile communication device.
