Abstract

A security device includes a processor defined to control operation of the security device. The security device also includes a radio defined in electrical communication with the processor. The security device also includes a location determination device defined in electrical communication with the processor. The processor, radio, and location determination device are defined to operate collaboratively to provide a wireless tracking and communication system. The security device also includes a shackle and a locking mechanism. The locking mechanism is defined in electrical communication with the processor. The processor is defined to operate the locking mechanism to control locking and unlocking of the shackle based on information obtained through the wireless tracking and communication system.

Claims

1. A locking device, comprising:

a processor defined to control operation of the locking device;

a radio defined in electrical communication with the processor;

a location determination device positioned within the locking device, the location determination device defined in electrical communication with the processor, wherein a combination of the processor, the radio, and the location determination device forms a wireless tracking and communication system;

a shackle;

a locking mechanism defined in electrical communication with the processor, wherein the processor is defined to operate the locking mechanism to control locking and unlocking of the shackle based on information obtained through the wireless tracking and communication system,

wherein the locking mechanism includes a latch plate defined to be movable to engage with and lock the shackle, and defined to be movable to disengage from and unlock the shackle,

wherein the locking mechanism also includes a cam defined to be movable in a first direction to engage with the latch plate such that movement of the cam in a second direction causes movement of the latch plate in the second direction, and

wherein the locking mechanism also includes a motor mechanically connected to control movement of the cam in the first direction to engage with the latch plate, wherein the motor is electrically connected to be controlled by the processor; and

lock sensors defined to determine a position of the cam relative to the latch plate and electrically communicate the determined position of the cam to the processor.

2. A locking device as recited in claim 1, further comprising:

a power source defined to supply electrical power to the processor, the radio, the location determination device, and the locking mechanism.

3. A locking device as recited in claim 2, further comprising:

a solar film electrically connected to the power source and defined to electrically re-charge the power source.

4. A locking device as recited in claim 1, wherein the radio is an international frequency radio, and wherein the location determination device is a global positioning system receiver device.

5. A locking device as recited in claim 1, wherein the processor is defined to operate the locking mechanism based on one or more of a proximity of the locking device to a secure wireless communication network, a terrestrial position of the locking device, and one or more commands received through the wireless tracking and communication system.

6. A locking device as recited in claim 1, wherein the shackle can only be unlocked through operation of the processor to control the motor to move the cam to engage the latch plate.

7. A locking device as recited in claim 1, further comprising:

a memory disposed in electrical communication with the processor for recording data, the data including program instructions for operating the wireless tracking and communication system, the data also including settings associated with operation of the locking device, the data also including a recording of a time-dependent status of the locking device;

a user interface display disposed in electrical communication with the processor and defined to visually render data recorded in the memory; and

a user interface control device disposed in electrical communication with the processor and defined to control which data is rendered in the user interface display.

8. A locking device as recited in claim 7, wherein the user interface display is a liquid crystal display, and wherein the user interface control device is a mechanical button.

9. A locking device, comprising:

a shell;

a shackle disposed within a channel inside the shell, the shackle defined to insert into an opening in the shell to close a shackle loop, the shackle defined to release from the opening in the shell to open the shackle loop;

a latch plate disposed inside the shell and defined to engage the shackle to lock the shackle when inserted into the shell to close the shackle loop;

a push plate disposed inside the shell, the push plate defined to be moved within the shell by an applied external force;

a motor mechanically fixed to the push plate;

a cam mechanically connected to be moved by the motor to engage with the latch plate, whereby movement of the push plate by the applied external force with the motor operated to engage the cam with the latch plate causes the latch plate to move to disengage from the shackle, thereby freeing the shackle to release from the shell to open the shackle loop; and

a processor defined onboard the locking device to monitor a state of the locking device and autonomously control the motor to move the cam based on the monitored state of the locking device.

10. A locking device as recited in claim 9, wherein the cam is rigidly connected to the motor such that movement of the motor through movement of the push plate causes corresponding movement of the cam.

11. A locking device as recited in claim 9, further comprising:

a first spring defined to disengage the cam from the latch plate when the motor is not powered to move the cam to engage with the latch plate;

a second spring defined to engage the latch plate with the shackle in an absence of the applied external force to move the push plate when the cam is also moved to engage the latch plate; and

a third spring defined to resist the external force applied to move the push plate such that the push plate is returned to its home position in the absence of the applied external force.

12. A locking device as recited in claim 9, wherein the push plate and latch plate physically interface with each other such that a force applied to the shackle is transferred through the shackle to the latch plate to the push plate to the shell.

13. A locking device as recited in claim 9, wherein the motor is isolated from a force applied to the shackle.

14. A locking device as recited in claim 9, further comprising:

an interlocking plate disposed within and secured to the shell to cover the push plate, the motor, the cam, the latch plate, and the shackle such that a locking mechanism of the locking device cannot be accessed without removal of the interlocking plate, and wherein the interlocking plate is secured to the shell by a fastener that is only accessible through the opening in the shell when the shackle is released from the opening in the shell to open the shackle loop.
