Device for selectively presenting objects

1. An assembly for selectively presenting objects, comprising:

a frame;

a carousel rotatably mounted to the frame for rotation about a generally vertical axis of rotation, the carousel including a plurality of object compartments arranged about the axis of rotation;

a servomotor operably connected with the carousel, the servomotor being configured to rotate the carousel about the axis of rotation, the servomotor associated with a detector; and

a controller, the controller configured to actuate the servomotor to rotate the carousel when the detector detects an attempt to rotate the carousel as the carousel is substantially stationary;

wherein at least one of the carousel compartments includes a feature configured to receive an operator's finger as it imparts angular displacement to the carousel.

2. The assembly defined in claim 1 , wherein the detector detects angular displacement of the motor and/or carousel as a result of the user's attempt.

3. The assembly defined in claim 1 , wherein the detector detects torque experienced by the motor as a result of the user's attempt.

4. The assembly defined in claim 1 , wherein the controller is configured to actuate the servomotor to rotate the carousel over a predetermined angular distance.

5. The assembly defined in claim 3 , wherein the controller is configured to maintain the carousel in a stationary position when no torque exceeding a predetermined magnitude is applied.

6. The assembly defined in claim 2 , wherein the controller is configured to maintain the carousel in a stationary position when no angular displacement exceeding a predetermined magnitude is imposed.

7. The assembly defined in claim 4 , wherein the predetermined angular distance is between about 40 and 240 degrees.

8. The assembly defined in claim 1 , wherein the frame and carousel define an entry opening, and wherein the controller is configured to rotate the carousel when an object is detected in a compartment adjacent to the entry opening.

9. The assembly defined in claim 1 , wherein the compartments are divided from each other by generally upright partitions.

10. The assembly defined in claim 1 , wherein the servomotor rotates the carousel at a speed of between about 2 and 30 rpm.

11. The assembly defined in claim 1 , wherein the controller is configured to cease rotation of the carousel when the detector detects an attempt to displace the rotating carousel in the opposite rotative direction.

12. An assembly for selectively presenting objects, comprising:

a frame;

a carousel rotatably mounted to the frame for rotation about a generally vertical axis of rotation, the carousel including a plurality of object compartments arranged about the axis of rotation;

a servomotor operably connected with the carousel, the servomotor being configured to rotate the carousel about the axis of rotation, the servomotor associated with a detector; and

a controller, the controller configured to actuate the servomotor to rotate the carousel when the detector detects an attempt to rotate the carousel as the carousel is substantially stationary;

further comprising guide rods mounted to the base and positioned to urge objects in compartments toward the axis of rotation.

13. An assembly for selectively presenting objects, comprising:

a frame;

a carousel rotatably mounted to the frame for rotation about a generally vertical axis of rotation, the carousel including a plurality of object compartments arranged about the axis of rotation;

a servomotor operably connected with the carousel, the servomotor being configured to rotate the carousel about the axis of rotation, the servomotor associated with a detector; and

a controller, the controller configured to actuate the servomotor to rotate the carousel when the detector detects an attempt by a user to rotate manually the carousel as the carousel is substantially stationary.

14. The assembly defined in claim 13 , wherein the detector detects angular displacement of the motor and/or carousel as a result of the user's attempt.

15. The assembly defined in claim 13 , wherein the detector detects torque experienced by the motor as a result of the user's attempt.

16. The assembly defined in claim 13 , wherein the controller is configured to actuate the servomotor to rotate the carousel over a predetermined angular distance.

17. The assembly defined in claim 16 , wherein the controller is configured to maintain the carousel in a stationary position when no torque exceeding a predetermined magnitude is applied.

18. The assembly defined in claim 14 , wherein the controller is configured to maintain the carousel in a stationary position when no angular displacement exceeding a predetermined magnitude is imposed.

19. The assembly defined in claim 17 , wherein the predetermined angular distance is between about 40 and 240 degrees.

20. The assembly defined in claim 13 , wherein the frame and carousel define an entry opening, and wherein the controller is configured to rotate the carousel when an object is detected in a compartment adjacent to the entry opening.

21. The assembly defined in claim 13 , wherein the compartments are divided from each other by generally upright partitions.

22. The assembly defined in claim 13 , wherein the servomotor rotates the carousel at a speed of between about 2 and 30 rpm.

23. The assembly defined in claim 13 , wherein the controller is configured to cease rotation of the carousel when the detector detects an attempt to displace the rotating carousel in the opposite rotative direction.
