Abstract

Systems and methods for electronic levels are disclosed. An electronic level can include one or more sensing elements configured to detect levelness of the electronic level. The electronic level can include a display including multiple output display elements arranged in an array that extends in a direction along a longitudinal axis of the electronic level and configured to display an indication of the levelness of the electronic level. The electronic level can include a controller coupled with the one or more sensing elements and the multiple output display elements. The controller may be configured to activate the one or more sensing elements to detect the levelness and activate one or more of the multiple output display elements to display the indication based on the levelness.

Claims (42)

1 . An electronic level, comprising:

one or more sensing elements configured to detect levelness of the electronic level;

a display comprising a plurality of output display elements arranged in an array that extends in a direction along a longitudinal axis of the electronic level and configured to display an indication of the levelness of the electronic level based on input from the one or more sensing elements; and

a controller coupled with the one or more sensing elements and the plurality of output display elements, the controller configured to:

activate the one or more sensing elements to detect the levelness; and

activate one or more of the plurality of output display elements to display the indication based on the levelness.

2 . The electronic level of claim 1 , wherein the display of the electronic level comprises a first lateral portion, a second lateral portion, and a medial portion disposed between the first lateral portion and the second lateral portion, the controller further configured to:

activate a traveling set of display elements of the plurality of output display elements, based on the levelness,

wherein the traveling set is activated at variable positions along the plurality of output display elements to be disposed entirely within the medial portion when the levelness is within a levelness threshold and disposed at least partially within one of the first lateral portion and the second lateral portion when the levelness is outside the levelness threshold.

3 . The electronic level of claim 2 , wherein the traveling set comprises consecutively adjacent output display elements.

4 . The electronic level of claim 2 , wherein the traveling set is displaced from a prior position of the variable positions by a single output display element.

5 . The electronic level of claim 2 , wherein at least one of the variable positions is disposed within both the medial portion and one of the first lateral portion or the second lateral portion.

6 . The electronic level of claim 1 , wherein the controller is further configured to:

select an indicator traveling mode from a set of indicator traveling modes based on an orientation value of the electronic level.

7 . The electronic level of claim 1 , wherein the controller is further configured to:

select an orientation mode from a set of orientation modes based on whether an orientation value of the electronic level satisfies an orientation threshold, wherein the set of orientation modes comprises a vertical mode and a horizontal mode.

8 . The electronic level of claim 1 , wherein the controller is further configured to:

activate a first output display element of the plurality and a second output display element of the plurality based on the levelness satisfying a threshold, wherein the first output display element and the second output display element are configured to indicate that the levelness of the electronic level is level.

9 . The electronic level of claim 1 , wherein the controller is further configured to:

activate a first output display element of the plurality and a second output display element of the plurality based on whether the electronic level is on, wherein the first output display element and the second output display element are configured to indicate guides that support perception of a center of the array.

10 . The electronic level of claim 1 , wherein the controller is further configured to:

increment the indication across the display based on a change of the levelness from a first levelness value to a second levelness value, wherein the change of the levelness satisfies a sensitivity threshold.

11 . The electronic level of claim 10 , wherein the controller is further configured to:

select a sensitivity mode from a set of sensitivity modes based on user input, wherein the sensitivity threshold is based on the selected sensitivity mode.

12 . The electronic level of claim 10 , wherein the controller configured to increment the indication is further configured to:

increment the indication based on a sensitivity mapping, the sensitivity mapping defining respective sensitivity thresholds for each output display element of the plurality.

13 . The electronic level of claim 1 , wherein a difference between a first levelness threshold associated with a first output display element and a second levelness threshold associated with a second output display element adjacent to the first output display element is greater than a difference between a third levelness threshold associated with a third output display element and a fourth levelness threshold associated with a fourth output display element adjacent to the third output display element.

14 . The electronic level of claim 13 , wherein the second output display element is adjacent to the third output display element.

15 . The electronic level of claim 1 , wherein the display comprises a first presentation surface positioned on an anterior side of the electronic level and a second presentation surface positioned on a posterior side of the electronic level, wherein:

the plurality of output display elements is shared by the first presentation surface and the second presentation surface; and

the plurality of output display elements are configured to simultaneously display the indication on both the first presentation surface and the second presentation surface.

16 . The electronic level of claim 1 , further comprising a light sensor configured to detect light, wherein the controller is further configured to change a brightness level of the output display elements based on the light.

17 . The electronic level of claim 1 , further comprising a leveled indicator to indicate when the electronic level is level.

18 . A display for an electronic level comprising:

a plurality of output display elements arranged in an array that extends in a direction along a longitudinal axis of the electronic level and configured to display an indication of the levelness of the electronic level based on input from one or more sensing elements of the electronic level; and

a controller coupled with the plurality of output display elements and the one or more sensing elements, the controller configured to:

activate the one or more sensing elements to detect the levelness; and

activate one or more of the plurality of output display elements to display the indication based on the levelness.

19 . The display of claim 18 , further comprising a first lateral portion, a second lateral portion, and a medial portion disposed between the first lateral portion and the second lateral portion, the controller further configured to:

activate a traveling set of display elements of the plurality of output display elements, based on the levelness,

wherein the traveling set is activated at variable positions along the plurality of output display elements to be disposed entirely within the medial portion when the levelness is within a levelness threshold and disposed at least partially within one of the first lateral portion and the second lateral portion when the levelness is outside the levelness threshold.

20 . The display of claim 18 , wherein the controller is further configured to: select an indicator traveling mode from a set of indicators traveling modes based on an orientation value of the electronic level.
