Abstract
A plunger head for a fluid injection device includes a transducer disposed in the plunger head to measure a compressive force when applied to the plunger head. The plunger head also includes a power source and a microcontroller disposed in the plunger head. The microcontroller is coupled to the power source and the transducer, and the microcontroller is coupled to enter a high-power mode in response to sensing application of the compressive force to the plunger head.
Claims20
A fluid injection device, comprising:
- a transducer to output a signal;
- a power source;
- a temperature sensor to measure a temperature representative of a fluid in the fluid injection device;
- and
- a microcontroller coupled to the power source, the transducer, the temperature sensor, and a memory, the memory including instructions that when executed by the microcontroller causes the fluid injection device to perform operations including:
- transition between individual modes included in a plurality of operative modes of the fluid injection device in response to the microcontroller receiving the signal output by the transducer, wherein the plurality of operative modes includes an off state, a power conservation mode, and a high-power mode, and wherein the fluid injection device consumes more power when in the high-power mode relative to when the fluid injection device is in the power conservation mode;
- and
- periodically measure the temperature with the temperature sensor when the fluid injection device is in either of the power conservation mode or the high-power mode, wherein a measurement frequency of the temperature is less during the power conservation mode than the high-power mode.
At least one non-transitory storage medium that provides instructions that, when executed by a fluid injection device, causes the fluid injection device to perform operations comprising:
- transition between individual modes included in a plurality of operative modes of the fluid injection device in response to a signal, wherein the plurality of operative modes includes an off state, a power conservation mode, and a high-power mode, and wherein the fluid injection device consumes more power when in the high-power mode relative to when the fluid injection device is in the power conservation mode;
- and
- periodically measure a temperature representative of a fluid in the fluid injection device when the fluid injection device is in either of the power conservation mode or the high-power mode, wherein a measurement frequency of the temperature is less during the power conservation mode than the high-power mode.
