Abstract

A blending system is shown and described herein. The blending system may include a base including a motor, a blade selectively and operably engaged with the base, where the motor rotates the blade, a container having an open end and a lid configured to cover the open end. The blending system may also include an optical interlock detector that may include a camera positioned on the base and indicia positioned at a predetermined location on a lid, wherein the camera detects the indicia and position of the lid to permit operation of the blender.

First claim

What is claimed is:

1. A blending system comprising:
a base housing a motor;
a container operatively coupled to the base;
a blade assembly operatively disposed within the container, the blade assembly operatively engaged with the motor;
a lid operatively attached to the container; and
an interlock detector comprising at least one image sensor disposed within the base and positioned such that a field of view of the at least one image sensor covers an area above the base where, when in an operative position, a plurality of portions of the container and the lid are disposed, and wherein the interlock detector processes, based at least in part on data captured by the at least one image sensor, spatial positions of the container and lid relative to the base to determine whether the container, the lid, and the base are interlocked.

2. The blending system of claim 1 , wherein the interlock detector further controls operation of the motor based on determining whether the container, the lid, and the base are interlocked.

3. The blending system of claim 2 , wherein
in response to determining that the container, the lid, and the base are interlocked, the interlock detector permits operation of the motor; and
in response to determining that the container, the lid, and the base are not interlocked, the interlock detector prevents operation of the motor.

4. The blending system of claim 2 , wherein the interlock detector further controls operation of the motor based on determining an association with the container, the lid, and the base.

5. The blending system of claim 4 , wherein
in response to determining that the container, the lid, and the base are interlocked and are associated with an operable combination, the interlock detector permits operation of the motor; and
in response to determining that the container, the lid, and the base are interlocked and are not associated with an operable combination, the interlock detector prevents operation of the motor.

6. The blending system of claim 1 , wherein the at least one image sensor comprises at least one of camera, a laser sensor, or a scanner configured to communicate with the interlock control component.

7. The blending system of claim 1 , wherein the lid comprises at least one indicia disposed thereon, the indicia configured to be recognizable by the interlock detector.

8. The blending system of claim 7 , wherein the lid includes a protrusion and wherein the at least one indicia is disposed on the protrusion.

9. The blending system of claim 8 , wherein the protrusion extends outwardly such that, when the lid is operatively attached to the container, at least a portion of the protrusion is in the field of view of the at least one image sensor.

10. The blending system of claim 7 , wherein the indicia is at least one of a one-dimensional barcode or a two-dimensional barcode.

11. A blending system comprising:
a base comprising a housing, the housing encasing a motor;
a blade within a container;
a lid configured to cover an open end of the container; and
an interlock detector comprising a camera disposed within the base and operatively capturing one or more images of an area above the housing,
wherein the interlock detector utilizes a pattern recognition process on the one or more images to recognize characteristics of the lid and the container in the one or more images to determine whether the container, lid, and housing are arranged in an operative position, and
wherein the interlock detector controls operation of the motor based on determining that the container, lid, and housing are arranged in an operative position.

12. The blending system of claim 11 , wherein the interlock detector further determines the position of the lid based on the pattern recognition process.

13. The blending system of claim 11 , wherein the camera comprises a lens, the lens disposed proximal to a surface of the housing.

14. The blending system of claim 11 , wherein the camera further comprises a field-of-view directed towards the open end of the container such that at least a portion of the lid is within the field of view when the lid covers the open end of the container.

15. A blending system comprising:
a base comprising a motor;
a blade in operative communication with the motor and selectively engaged with the base;
a container having an open end, a closed end, and a radial wall disposed between the open end and closed end, wherein the closed end is operatively coupled to the blade;
a lid operatively connected to the open end when in a closed position, wherein the lid comprises at least one indicia disposed thereon; and
an interlock detector comprising one or more image sensors disposed on the base for determining, based at least in part on the one or more image sensors detecting the indicia, the spatial relationship of the lid relative to the container and the base, to control operability of the motor, wherein the one or more image sensors comprise a focusable lens.

16. The blending system of claim 13 , wherein the lens comprises at least one of a manual-focus or an automatic-focus lens.

17. The blending system of claim 13 , wherein the lens comprises at least one of a fixed-focus or a full-focus lens.

18. The blending system of claim 1 , wherein the plurality of portions of the container comprises at least one of a wall, a shoulder, a spout, or a handle.
