Abstract
Liquid level sensing apparatus and related methods are disclosed. An example method includes moving a cannula to pierce a seal of a container to provide access to a liquid in a cavity of the container; moving a probe through a passageway of the cannula and into the cavity of the container; and when the probe is at least partially positioned in the cannula: providing a first signal to the probe to cause the probe to emit a first electrical field; and providing a second signal to the cannula to cause the cannula to emit a second electrical field.
Claims20
A method comprising:
- moving a cannula to pierce a seal of a container to provide access to a liquid in a cavity of the container;
- moving a probe through a passageway of the cannula and into the cavity of the container;
- and
- when the probe is at least partially positioned in the cannula:
- providing a first signal to the probe to cause the probe to emit a first electrical field;
- and
- providing a second signal to the cannula to cause the cannula to emit a second electrical field.
A non-transitory computer-readable medium comprising instructions that, when executed, cause a machine to:
- move a cannula to pierce a seal of a container to provide access to a liquid in a cavity of the container;
- move a probe through a passageway of the cannula and into the cavity of the container;
- and
- when the probe is at least partially positioned in the cannula:
- provide a first signal to the probe to cause the probe to emit a first electrical field;
- and
- provide a second signal to the cannula to cause the cannula to emit a second electrical field.
A liquid sensing apparatus comprising:
- means for moving a means for piercing a seal of a container to provide access to a liquid in a cavity of the container;
- means for moving a means for aspirating liquid through a passageway of the means for piercing the container and into the cavity of the container;
- and
- means for generating a first signal to the means for aspirating liquid and a second signal to the means for piercing the container when the means for aspirating liquid is at least partially positioned in the passageway of the means for piercing the container, the first signal to cause the means for aspirating liquid to emit a first electrical field and second signal to cause the means for piercing the container to emit a second electrical field.
