Abstract

A knife station includes a knife block defining a plurality of slots for receiving a plurality of cutlery objects. A locking assembly selectively locks the cutlery objects in their respective slot, e.g., using a locking pin that passes through an aperture in the blade. A controller is operably coupled to an audio device, such as a microphone, for receiving voice commands. The voice commands are converted to text commands using AI-based speech recognition technology and the text commands are compared to a database of text commands to identify a target cutlery object from the cutlery objects in the knife block. The controller may then illuminate a light emitting diode next to the target cutlery and unlock only that piece of cutlery so that the user may withdraw it from the knife block.

First claim

What is claimed is:

1. A knife station comprising:
a knife block defining a plurality of slots;
a plurality of cutlery objects, each of the plurality of cutlery objects being configured for receipt within one of the plurality of slots;
a locking assembly for selectively locking one or more of the plurality of cutlery objects within the plurality of slots; and
a controller operably coupled to the locking assembly, the controller being configured to:
receive a voice command from a user;
identify a target cutlery object from the plurality of cutlery objects based at least in part on the voice command; and
unlock the identified target cutlery object so that the user may remove it from the knife block, wherein remaining cutlery objects of the plurality of cutlery objects remain locked.

2. The knife station of claim 1 , wherein identifying the target cutlery object comprises:
converting the voice command to a text command using a speech recognition technology; and
determining the target cutlery object based on the text command.

3. The knife station of claim 2 , wherein determining the target cutlery object from the text command comprises:
comparing the text command to a database of text commands to associate the text command with the target cutlery object.

4. The knife station of claim 2 , wherein the speech recognition technology comprises an artificial intelligence or machine learning technique to convert the voice command.

5. The knife station of claim 1 , wherein the controller is further configured to:
determine that the voice command is not communicated from an authorized user; and
operate the locking mechanism to lock each of the plurality of knives if the voice command is not communicated from the authorized user.

6. The knife station of claim 5 , wherein determining that the voice command is not communicated from the authorized user comprises authenticating a particular user or detecting a tone of the voice command.

7. The knife station of claim 1 , wherein the locking assembly unlocks the target cutlery object while keeping each of the remaining of the plurality of cutlery objects locked in the knife block.

8. The knife station of claim 1 , further comprising:
an indicator system for selectively identifying one or more of the plurality of cutlery objects within the knife block.

9. The knife station of claim 8 , wherein the indicator system comprises:
a plurality of light emitting diodes, each of the plurality of light emitting diodes being associated with one of the plurality of cutlery objects and being selectively illuminated to identify the target cutlery object of the plurality of cutlery objects.

10. The knife station of claim 8 , wherein the controller is configured to:
illuminate the knife block proximate the target cutlery object.

11. The knife station of claim 1 , wherein the voice command comprises a type of cut to be made and a food type of food to be cut.

12. The knife station of claim 1 , wherein each of the plurality of cutlery objects defines an aperture, and wherein the locking assembly comprises:
a plurality of linear actuators, each of the plurality of linear actuators comprising a locking pin that selectively extends into the aperture of one of the plurality of knives.

13. The knife station of claim 1 , wherein the locking assembly comprises:
a clamping member operably coupled to an actuator for selectively clamping a blade of one of the plurality of knives.

14. The knife station of claim 1 , further comprising:
an audio input device for receiving the voice command.

15. A method of operating a knife station, the knife station comprising a knife block defining a plurality of slots for receiving a plurality of cutlery objects and a locking assembly for selectively locking one or more of the plurality of cutlery objects within the plurality of slots, the method comprising:
receiving a voice command from a user;
identifying a target cutlery object from the plurality of cutlery objects based at least in part on the voice command; and
unlocking the identified target cutlery object so that the user may remove it from the knife block, wherein remaining cutlery objects of the plurality of cutlery objects remain locked.

16. The method of claim 15 , wherein identifying the target cutlery object comprises:
converting the voice command to a text command using a speech recognition technology; and
determining the target cutlery object based on the text command.

17. The method of claim 16 , wherein the speech recognition technology comprises an artificial intelligence or machine learning technique to convert the voice command.

18. The method of claim 15 , further comprising:
determining that the voice command is not communicated from an authorized user; and
operating the locking mechanism to lock each of the plurality of knives if the voice command is not communicated from the authorized user.

19. The method of claim 15 , wherein the knife station further comprises an indicator system for selectively identifying one or more of the plurality of cutlery objects within the knife block, the method comprising:
illuminating the knife block proximate the target cutlery object.

20. The method of claim 15 , wherein each of the plurality of cutlery objects defines an aperture, and wherein the locking assembly comprises:
a plurality of linear actuators, each of the plurality of linear actuators comprising a locking pin that selectively extends into the aperture of one of the plurality of knives.
