Abstract: Some embodiments of a device comprise a cleaning-fluid-supply reservoir; a cleaning-fluid-supply conduit; one or more electrical connectors that are configured to be attached to a printhead and supply electrical signals to the printhead; one or more memories; and one or more processors that are in communication with the one or more memories. Also, the one or more processors cooperate with the one or more memories to cause the device to perform operations that include supplying cleaning fluid from the cleaning-fluid-supply reservoir, through the cleaning-fluid-supply conduit, to the printhead, and while supplying the cleaning fluid to the printhead, sending a signal to the printhead, through the one or more electrical connectors, to activate one or more piezo-electric actuators of the printhead.

Abstract: A method of determining an object distance from a vehicle includes sending a first transmission signal during a first burst period from a first transmitter, listening for a first reflection signal during a first listen period in a receiver, and sending a second transmission signal during a second burst period from a second transmitter. The second transmission signal is sent based on a time when the first transmission signal is sent.

Abstract: A method of parking a vehicle includes calibrating a wheel speed count of the vehicle based on a measured length that is external to the vehicle, and parking the vehicle based on the calibrated wheel speed count.

Abstract: A method of parking a running vehicle includes measuring a length of a parked vehicle that is proximate to a desired parking location, and estimating the width of the parked vehicle based on a regression equation. The running vehicle is parked based on the estimated width.

Abstract: A system and method for outputting outside air temperature information and signaling apparatus configured for outputting powertrain operating information, the system comprising instructions causing the at least one data processing device to determine a first instance of signal strength calibration for the ultrasonic sensor based on a last known instance of outside air temperature and a first instance of powertrain operating information, instructions causing the at least one data processing device to determine a vehicle operating condition requiring alteration of the signal strength calibration for the ultrasonic sensor, instructions for altering the signal strength calibration for the ultrasonic sensor and instructions for altering an outside air temperature to be displayed to a driver of the vehicle.

Abstract: Temperature compensation for ultrasonic sensors can have a significant error that is highly undesirable because temperature of ultrasonic sensors and the temperature of the medium through which they sense objects affect signal strength calibrations (e.g., echo thresholds) applied when detecting an object. In order to increase the detection capabilities and reported distance of an object, ultrasonic sensors need to adjust their detection criteria and distance calculations as the temperature of air surrounding a vehicle (i.e., outside air temperature) changes and also as the temperature of the sensor changes. Embodiments of the inventive subject matter provide for a simple, effective and consistent approach for determining a temperature upon which such detection criteria and distance calculation adjustments can be based.
