Abstract
A filter identification system is disclosed. The filter identification system may include an identification component disposed in a filter mount configured to hold a set of filters that includes a first filter and a second filter. The identification component may include a sensor system that may include a first sensor configured to provide a first output signal corresponding to a state of the first sensor, and a second sensor configured to provide a second output signal corresponding to a state of the second sensor. The sensor system may be configured to provide a single output signal that is based on the first output signal and the second output signal and indicates a combined state of the first sensor and the second sensor.
Claims20
A filter identification system, comprising:
- an identification component disposed in a filter mount configured to hold a set of filters that includes a first filter and a second filter,
- the identification component including a sensor system that includes:
- a first sensor configured to provide a first output signal corresponding to a state of the first sensor;
- and
- a second sensor configured to provide a second output signal corresponding to a state of the second sensor,
- the sensor system configured to provide a single output signal that is based on the first output signal and the second output signal and indicates a combined state of the first sensor and the second sensor.
A filter identification module, comprising:
- an identification component that includes a sensor system,
- the sensor system including:
- a first sensor configured to provide a first output signal corresponding to a state of the first sensor;
- and
- a second sensor configured to provide a second output signal corresponding to a state of the second sensor,
- the sensor system configured to provide a single output signal that is based on the first output signal and the second output signal and indicates a combined state of the first sensor and the second sensor;
- and
- a controller configured to identify a first filter within a threshold proximity of the first sensor and a second filter within the threshold proximity of the second sensor based on the single output signal.
A method, comprising:
- causing an input voltage to be supplied to an identification component that includes a sensor system including a first sensor configured to provide a first output signal corresponding to a state of the first sensor and a second sensor configured to provide a second output signal corresponding to a state of the second sensor,
- the identification component disposed in a filter mount configured to hold a set of filters that includes a first filter and a second filter;
- and
- receiving, from the identification component, a single output voltage that is based on the first output signal and the second output signal and that indicates a combined state of the first sensor and the second sensor.
