Odorant-releasing utensil
In an aspect, an eating utensil includes a controllable odorant emitter for delivering an odorant to a person who is eating or drinking from the eating utensil. The odorant may be delivered orthonasally or retronasally. The odorant may be used to stimulate or suppress appetite. In an aspect, a controllable odorant emitter is provided in an attachment that may be removably secured to an eating utensil. Related methods and systems for delivering odorant in connection with use of an eating utensil are described.
1. A method of delivering an odorant in connection with use of an eating utensil for delivering food or drink to a consumer, comprising:
releasing at least one odorant from at least one controllable odorant emitter carried by an eating utensil in response to a control signal generated by control circuitry carried by the eating utensil and operatively connected to the at least one controllable odorant emitter, the eating utensil comprising:
an ingestible substance-carrying portion adapted to carry a quantity of an ingestible substance to a mouth of a consumer; and
a support portion connected to the ingestible substance-carrying portion and configured to be engaged by a person's hand to permit the ingestible substance-carrying portion to be thereby moved to the mouth of the consumer.
2. The method of claim 1 , comprising receiving a signal from a remote device with a receiver carried by the eating utensil.
3. The method of claim 1 , wherein the at least one controllable odorant emitter is a part of the eating utensil.
4. The method of claim 1 , wherein the at least one controllable odorant emitter is a part of an attachment to the eating utensil, wherein the attachment is removably securable to the eating utensil such that the when secured to the eating utensil the attachment and parts thereof are carried by the eating utensil.
5. The method of claim 1 , comprising sensing a parameter indicative of at least a portion of the ingestible substance-carrying portion being inside the mouth of the consumer with a sensor carried by the eating utensil.
6. The method of claim 1 , comprising sensing a parameter indicative of the eating utensil being moved to or from the mouth of the consumer.
7. The method of claim 6 , including at least one of sensing proximity of the eating utensil to a skin surface of the consumer, sensing an acceleration, determining a rate at which the utensil is moved to or from the mouth of the consumer and determining how many times the eating utensil is moved to or from the mouth of the consumer.
8. The method of claim 1 , comprising sensing a parameter indicative of a weight of the ingestible substance carried by the ingestible substance-carrying portion with a sensor carried by the eating utensil.
9. The method claim 1 , comprising sensing a parameter indicative of a component of the ingestible substance carried by the ingestible substance-carrying portion with a sensor carried by the eating utensil.
10. The method of claim 1 , comprising releasing the at least one odorant from the at least one controllable odorant emitter according to a program.
11. The method of claim 10 , wherein releasing the at least one odorant from the at least one controllable odorant emitter according to a program includes releasing the at least one odorant according to a predetermined instruction set under control of control circuitry carried by the eating utensil.
12. The method of claim 1 , comprising detecting a start of use of the eating utensil.
13. The method of claim 12 , comprising controlling release of the at least one odorant from the at least one controllable odorant emitter based at least in part on how long the eating utensil has been in use.
14. The method of claim 13 , wherein controlling release of the at least one odorant from the at least one controllable odorant emitter based at least in part on how long the eating utensil has been in use includes at least one of starting release of the at least one odorant after the eating utensil has been in use for a specified amount of time, ending release of the at least one odorant after the eating utensil has been in use for a specified amount of time, starting release of at least a second odorant after the eating utensil has been in use for a specified amount of time, and starting release of at least one odorant from at least one second location on the eating utensil after the eating utensil has been in use for a specified amount of time.
15. The method of claim 12 , wherein detecting the start of use of the eating utensil includes at least one of detecting activation of a user-activatable switch, detecting a repetitive pattern in a signal sensed from a sensor carried by the eating utensil, determining that the eating utensil is being moved to or from the mouth of the consumer, detecting at least a component of the ingestible substance, and detecting a weight of the ingestible substance carried by the eating utensil.
16. A method of delivering an odorant in connection with use of an eating utensil for delivering food or drink to a consumer, comprising:
releasing at least one odorant from at least one controllable odorant emitter carried by an eating utensil in response to a control signal, the eating utensil comprising:
an ingestible substance-carrying portion adapted to carry a quantity of an ingestible substance to a mouth of a consumer; and
a support portion connected to the ingestible substance-carrying portion and configured to be engaged by a person's hand to permit the ingestible substance-carrying portion to be thereby moved to the mouth of the consumer;
wherein the at least one controllable odorant emitter includes at least one expulsion mechanism adapted to expel the odorant from the controllable odorant emitter, and wherein releasing the at least one odorant from the at least one controllable odorant emitter includes activating the at least one expulsion mechanism.
17. A method of delivering an odorant in connection with use of an eating utensil for delivering food or drink to a consumer, comprising:
releasing at least one odorant from at least one controllable odorant emitter carried by an eating utensil in response to a control signal, the eating utensil comprising:
an ingestible substance-carrying portion adapted to carry a quantity of an ingestible substance to a mouth of a consumer; and
a support portion connected to the ingestible substance-carrying portion and configured to be engaged by a person's hand to permit the ingestible substance-carrying portion to be thereby moved to the mouth of the consumer;
comprising releasing a second odorant, wherein the at least one odorant released from the at least one controllable odorant emitter is a first odorant released from a first controllable odorant emitter; and wherein the method includes at least one of releasing the second odorant from the first controllable odorant emitter; releasing the second odorant from a second controllable odorant emitter; releasing a second odorant that is different from the first odorant; releasing the first odorant and the second odorant from controllable odorant emitters located at two spatially separated locations; releasing the first odorant and the second odorant at different times; and mixing the first odorant and the second odorant.
