Abstract
A system comprising a storage member and a load cell. The storage member is for storing a product. The load cell measures a force applied to the load cell. At least part of the force applied to the load cell is provided, directly or indirectly, by a weight of the product. The system is configured to determine a quantity of the product based, at least in part, on the force measured by the load cell.
Claims20
A system comprising:
- a storage member for storing a product;
- and
- a load cell that measures a force applied to the load cell;
- wherein at least part of the force applied to the load cell is provided, directly or indirectly, by a weight of the product;
- wherein the system is configured to determine a quantity of the product stored within the storage member based, at least in part, on the force measured by the load cell;
- wherein the system is configured to identify at least one of the storage member and the product based, at least in part, on the force measured by the load cell;
- wherein the system comprises a dispenser for dispensing the product;
- and
- wherein the system is configured to adjust an operating parameter of the dispenser based, at least in part, on the identity of the at least one of the storage member and the product.

A system comprising:
- a storage member for storing a product;
- and
- a load cell that measures a force applied to the load cell;
- wherein at least part of the force applied to the load cell is provided, directly or indirectly, by a weight of the product;
- wherein the system is configured to determine a quantity of the product stored within the storage member based, at least in part, on the force measured by the load cell;
- wherein the system comprises a dispenser for dispensing the product;
- wherein the storage member comprises a rigid reservoir or a collapsible reservoir, and the product is a fluid;
- wherein the collapsible reservoir collapses as the fluid is dispensed from the collapsible reservoir;
- wherein the system comprises a housing;
- wherein the collapsible reservoir engages with the housing as the collapsible reservoir collapses;
- wherein the engagement of the collapsible reservoir with the housing is detectable as a change in a pattern of the force measured by the load cell;
- and
- wherein the system is configured to determine whether the storage member comprises the rigid reservoir or the collapsible reservoir based, at least in part, on the pattern of the force measured by the load cell.
