Abstract
An accurate, easy-to-use, low cost level indication system can be easily installed on the exterior or interior of an RV. The device provides a visible and/or audible level indication that can be viewed from within the cab of the tow vehicle or motor home day or night. The device provides level indication along the 2 main RV axis's (side to side and front to back). The device can be calibrated at any time by the operator. Calibration can be performed on uneven terrain. The device can also store arrival inclination information for later recall during departure preparations.
Claims20
An electronic level indicating device for leveling at least one axis of a mobile platform comprising:
- At least one sensor configured to be coupled to a mobile platform, each sensor for detecting and signaling a measured inclination level of an axis of the mobile platform;
- A controller coupled to the at least one sensor;
- A display configured to be viewable by the user and coupled to the controller, the display including at least a level indicating visual indicator and a plurality of out of level visual indicators;
- and
- A level calibration mechanism configured to allow the user to set a preferred level position for the device, wherein the level indicating visual indicator is configured to indicate when the measured inclination level is about equal to the user set preferred level position and the out of level visual indicators are configured to indicate when the measured inclination level is not about equal to the user set preferred level position.
An electronic level indicating device for leveling at least one axis of a mobile platform comprising:
- At least one sensor configured to be coupled to a mobile platform, each sensor for detecting and signaling a measured inclination level of an axis of the mobile platform;
- A controller coupled to the at least one sensor;
- A display configured to be viewable by the user and coupled to the controller, the display including at least one level indicating visual indicator and a plurality of out of level visual indicators;
- A level storage mechanism that will store a current measured inclination level of the axis of the mobile platform;
- and
- A stored level recall mechanism that will recall a stored measured inclination level and will visually display the stored measured inclination level to the user using at least one of the level indicating visual indicator and the plurality of out of level visual indicators, wherein the stored measured inclination level is displayed when recalled along with a current measured inclination level.
An electronic level indicating device for leveling at least one axis of a mobile platform comprising:
- At least one sensor configured to be coupled to a mobile platform, each sensor for detecting and signaling a measured inclination level of an axis of the mobile platform;
- A controller coupled to the at least one sensor;
- A display configured to be viewable by the user and coupled to the controller, the display including at least one level indicating visual indicator, a plurality of out of level visual indicators forming an array of out of level visual indicators, and a unit measurement indicator visually identifying the unit measurements of the out of level visual indicators, and wherein each sequential out of level visual indicator is associated with a fixed unit measurement that is visually identified.
