Abstract

A method for operating a feeding device, the feeding device including a feed arm operative to transfer food from a food compartment to a feed position, typically adjacent an individual. The method includes operating the feeding device in a predetermined pattern or sequence to retrieve food from the food compartment. The method uses multiple utensil pathways whereby the feeding device includes an initial utensil pattern or sequence and a subsequent pattern or sequence.

Claims

1. A method for operating a feeding device comprising the steps of:

providing a food compartment;

providing a feed arm supporting a utensil;

providing an initial utensil sequence, including a first predetermined pathway for said utensil relative to the food compartment;

providing a continuous utensil sequence, including a predetermined pathway for said utensil relative to a food compartment;

cycling the feeding device through the initial utensil sequence; and

upon completion of the initial utensil sequence optionally cycling the feeding device through said continuous utensil sequence.

2. The method of claim 1 wherein said initial utensil sequence includes a first retrieval path, a second retrieval path, a third retrieval path, and a fourth retrieval path.

3. The method of claim 1 wherein said continuous utensil sequence includes a fifth retrieval path, a sixth retrieval path, and a seventh retrieval path.

4. The method of claim 2 wherein said food compartment includes a centerline and a midline, said centerline extending from a back edge of the food compartment to a tab and dividing the food compartment, said midline extending between the tab and the back edge and dividing the food compartment wherein the centerline and midline intersect in the food compartment;

said first retrieval path starts at the back edge and follows the centerline toward the tab until reaching the midline;

said second retrieval path starts at an edge of the food compartment on a first side of the centerline at an angle with respect to the centerline and continues at said angle until reaching the midline;

said third retrieval path starts at an edge of the food compartment on a second side of the centerline at an angle with respect to the centerline and continues at said angle until reaching the midline; and

said fourth retrieval path starts near the tab, follows along a first side of the food compartment to a position adjacent the rear end of the food compartment, returns near the tab, follows along a second side of the food compartment to a position adjacent the rear end of the food compartment, and starts at the back edge and follows the centerline until reaching the tab.

5. The method of claim 3 wherein said food compartment includes a centerline and a midline, said centerline extending from a back edge of the food compartment to a tab and dividing the food compartment, said midline extending between the tab and the back edge and dividing the food compartment wherein the centerline and midline intersect in the food compartment;

said fifth retrieval path starts at an edge of the food compartment on a first side of the centerline at an angle with respect to the centerline and continues at said angle until reaching the midline and then follows the centerline until reaching the tab;

said sixth retrieval path starts at an edge of the food compartment on a second side of the centerline at an angle with respect to the centerline and continues at said angle until reaching the midline and then follows the centerline until reaching the tab; and

said seventh retrieval path starts near the tab, follows along a first side of the food compartment to a position adjacent the rear end of the food compartment, returns near the tab, follows along a second side of the food compartment to a position adjacent the rear end of the food compartment, and starts at the back edge and follows the centerline until reaching the tab.

6. The method of claim 1 wherein said food compartment includes a centerline and a midline, said centerline extending from a back edge of the food compartment to a tab and dividing the food compartment, said midline extending between the tab and the back edge and dividing the food compartment wherein the centerline and midline intersect in the food compartment;

said initial utensil sequence includes;

a first retrieval path starting at the back edge and following the centerline toward the tab until reaching the midline;

a second retrieval path starting at an edge of the food compartment on a first side of the centerline at an angle with respect to the centerline and continuing at said angle until reaching the midline;

a third retrieval path starting at an edge of the food compartment on a second side of the centerline at an angle with respect to the centerline and continuing at said angle until reaching the midline;

a fourth retrieval path starting near the tab, following along a first side of the food compartment to a position adjacent the rear end of the food compartment, returning near the tab, continuing along a second side of the food compartment to a position adjacent the rear end of the food compartment, and starting at the back edge and following the centerline until reaching the tab;

said continuous utensil sequence includes;

a fifth retrieval path starting at an edge of the food compartment on a first side of the centerline at an angle with respect to the centerline and continuing at said angle until reaching the midline and then following the centerline until reaching the tab;

a sixth retrieval path starting at an edge of the food compartment on a second side of the centerline at an angle with respect to the centerline and continuing at said angle until reaching the midline and then following the centerline until reaching the tab; and

a seventh retrieval path starting near the tab, following along a first side of the food compartment to a position adjacent the rear end of the food compartment returning near the tab, following along a second side of the food compartment to a position adjacent the rear end of the food compartment, and starting at the back edge and following the centerline until reaching the tab.

7. The method of claim 1 wherein upon initially completing said continuous utensil sequence, said feed utensil continues to perform said continuous utensil sequence.

8. A method for operating a feeding device comprising the steps of:

providing a food compartment;

moving a utensil relative to the food compartment through multiple retrieval paths, said retrieval paths including;

a linear path extending at least partially along a line between opposing edges of said food compartment;

an angular path extending at least partially along a line at an angle with respect to the line between opposing edges of said food compartment;

an arcuate path extending at least partially along a line adjacent an arcuate sidewall of said food compartment.

9. The method of claim 8 wherein said retrieval paths includes a combination path, said combination path including a linear portion extending at least partially along a line between opposing edges of said food compartment and an angular portion extending at least partially along a line at an angle with respect to the line between opposing edges of said food compartment.

10. A method for operating a feeding device comprising the steps of:

providing a user input device, wherein actuating the user input device generates a retrieve request;

providing a utensil movable through a predetermined utensil pathway;

moving the utensil through a first predetermined utensil pathway the first time the user input device generates a retrieve request;

moving the utensil through a second predetermined utensil pathway the second time the user input device generates a retrieve request;

moving the utensil through a third predetermined utensil pathway the third time the user input device generates a retrieve request; and

moving the utensil through a fourth predetermined utensil pathway the fourth time the user input device generates a retrieve request.

11. The method of claim 10 including the steps of:

moving the utensil through a fifth predetermined utensil pathway the fifth time the user input device generates a retrieve request;

moving the utensil through a sixth predetermined utensil pathway the sixth time the user input device generates a retrieve request; and

moving the utensil through a seventh predetermined utensil pathway the seventh time the user input device generates a retrieve request.

12. The method of claim 11 including the step of following the sequence of the fifth, sixth and seventh predetermined utensil pathways upon receiving additional retrieve requests.

13. The method of claim 11 wherein said first, second, third, and fourth predetermined utensil pathways form an initial utensil sequence;

and
