Abstract

A method of managing a license for a software module of a vehicle having a plurality of operating states includes receiving, by a processor, license term data of the license. The license term data includes an expiration time limit of the license. The method also includes observing, by a sensor, a condition of the vehicle. Additionally, the method includes determining, by the processor, an operating state of the vehicle based on the condition observed by the sensor. Furthermore, the method includes determining, by the processor, whether to deny access to the software module according to the expiration time limit based on the determined operating state.

First claim

What is claimed is:

1. A method of managing a license for a software module of a vehicle having a plurality of operating states, the method comprising:
receiving, by a processor, license term data of the license, the license term data including an expiration time limit of the license;
observing, by a sensor, a condition of the vehicle;
determining, by the processor, an operating state of the vehicle based on the condition observed by the sensor; and
determining, by the processor, whether to deny access to the software module according to the expiration time limit based on the determined operating state.

2. The method of claim 1 , wherein receiving the license term data includes receiving a first expiration time limit of the license;
wherein determining the operating state includes determining, by the processor, that the vehicle is in one of a first operating state and a second operating state based on the condition observed by the sensor;
further comprising denying user access to the software module according to the first expiration time limit based on the determination that the vehicle is in the first operating state; and
further comprising denying user access to the software module according to an extended expiration time limit based on the determination that the vehicle is in the second operating state.

3. The method of claim 2 , further comprising determining, by the processor, the extended expiration time limit by increasing the first expiration time limit by a predetermined time interval.

4. The method of claim 2 , wherein the vehicle is an aircraft;
wherein observing the condition includes observing a current airspeed of the aircraft;
further comprising comparing, by the processor, the observed current airspeed to a predetermined threshold;
further comprising determining, by the processor, whether the aircraft is airborne or on ground based on the comparison of the current airspeed and the predetermined threshold;
further comprising denying user access to the software module according to the first expiration time limit based on the determination that the vehicle is on ground; and
further comprising denying user access to the software module according to the extended expiration time limit based on the determination that the vehicle is airborne.

5. The method of claim 2 , wherein the vehicle is an aircraft;
wherein observing the condition includes observing a current altitude of the aircraft;
further comprising comparing, by the processor, the observed current altitude to a predetermined threshold;
further comprising determining, by the processor, whether the aircraft is airborne or on ground based on the comparison of the current altitude and the predetermined threshold;
further comprising denying user access to the software module according to the first expiration time limit based on the determination that the vehicle is on ground; and
further comprising denying user access to the software module according to the extended expiration time limit based on the determination that the vehicle is airborne.

6. The method of claim 2 , wherein the vehicle is an aircraft with a landing gear, the landing gear being variable between a first condition and a second condition;
wherein observing the condition includes observing, by the sensor, whether the landing gear is in the first condition or the second condition;
further comprising determining, by the processor, that the aircraft is airborne based on the sensor observing the first condition of the landing gear;
further comprising determining, by the processor, that the aircraft is on ground based on the sensor observing the second condition of the landing gear;
further comprising denying user access to the software module according to the first expiration time limit based on the determination that the vehicle is on ground; and
further comprising denying user access to the software module according to the extended expiration time limit based on the determination that the vehicle is airborne.

7. The method of claim 2 , wherein the vehicle is an aircraft with a parking brake, the parking brake being moveable between an engaged position and a disengaged position;
wherein observing the condition includes observing, by the sensor, whether the parking brake is in the engaged position or the disengaged position;
further comprising determining, by the processor, that the aircraft is airborne based on the sensor observing the parking brake in the disengaged position;
further comprising determining, by the processor, that the aircraft is on ground based on the sensor observing the parking brake in the engaged position;
further comprising denying user access to the software module according to the first expiration time limit based on the determination that the vehicle is on ground; and
further comprising denying user access to the software module according to the extended expiration time limit based on the determination that the vehicle is airborne.

8. The method of claim 2 , further comprising receiving, by the processor, clock data from a universally coordinated clock, the clock data corresponding to a current time; and
further comprising comparing the current time to the first expiration time limit to determine an expiration status of the license.

9. The method of claim 1 , wherein the software module is one of a plurality of software modules, and further comprising:
determining, by the processor, whether the plurality of software modules are licensable; and
determining, by the processor, whether a trial license is available for the licenseable ones of the software modules.

10. A system for managing a license for a software module of a vehicle, the system comprising:
a processor configured to receive license term data of the license, the license term data including an expiration time limit of the license; and
a sensor configured to observe a condition of the vehicle;
the processor configured to determine an operating state of the vehicle based on the observation by the sensor;
the processor configured to determine whether to deny access to the software module according to the expiration time limit based on the determined operating state of the vehicle.

11. The system of claim 10 ,
wherein the processor is configured to receive a first expiration time limit of the license;
wherein the processor is configured to determine that the vehicle is in one of a first operating state and a second operating state based on the observation by the sensor;
wherein the processor is configured to deny user access to the software module according to the first expiration time limit based on the determination that the vehicle is in the first operating state; and
wherein the processor is configured to deny user access to the software module according to an extended expiration time limit based on the determination that the vehicle is in the second operating state.

12. The system of claim 11 , wherein the processor is configured to determine the extended expiration time limit by increasing the first expiration time limit by a predetermined time interval.

13. The system of claim 11 , wherein the vehicle is an aircraft;
wherein the sensor is an airspeed sensor configured to observe a current airspeed of the aircraft;
wherein the processor is configured to compare the observed current airspeed to a predetermined threshold;
wherein the processor is configured to determine whether the aircraft is airborne or on ground based on the comparison of the current airspeed and the predetermined threshold;
wherein the processor is configured to deny user access to the software module according to t
