Abstract
A level, such as a digital level, with various features or embodiments, such as an ultrasonically welded lens covering a display screen, a pipe insert molded in front of a light sensor, one or more button assemblies, and cartridge assemblies that are used to secure compartments within the frame of a level.
Claims20
A level comprising:
- a planar base surface;
- a top surface opposing the base surface;
- an orientation sensor configured to measure an orientation of one of the top and bottom surfaces with respect to a perceived direction of the force of gravity;
- a controller that calculates an orientation difference between the measured orientation and a target orientation;
- a light sensing module that measures a brightness level, the light sensing module comprising:
- a primary channel;
- a front surface defined by primary channel, the front surface in visual communication with an exterior of the level;
- a light sensor that measures the brightness level;
- and
- a light impediment between the light sensor and the primary channel, the light impediment configured to interfere with light transiting from the front surface to the light sensor;
- and
- a display that emits an image that corresponds to the orientation difference, the image comprising a brightness that is at least partly based on a measurement by the light sensor.

A method of manufacturing a level comprising:
- coupling an orientation sensor to a level, the orientation sensor configured to measure an orientation of the level with respect to a perceived direction of the force of gravity;
- the level comprising:
- a body comprising a longitudinal axis, the body defining a cavity that comprises an upper channel and a lower channel;
- a planar base surface defined by the body;
- and
- a top surface defined by the body and opposing the base surface;
- inserting a cartridge assembly within the cavity, the cartridge assembly comprising:
- a first cartridge comprising a vertical portion and a horizontal portion, the horizontal portion disposed within the lower channel;
- a second cartridge comprising a vertical portion and a horizontal portion, the horizontal portion disposed within the upper channel, and the second cartridge's vertical portion slidably engaged with the first cartridge's vertical portion;
- a third cartridge comprising a vertical portion and a horizontal portion, the horizontal portion disposed within the lower channel;
- a fourth cartridge comprising a vertical portion and a horizontal portion, the horizontal portion disposed within the upper channel, and the fourth cartridge's vertical portion slidably engaged with the third cartridge's vertical portion;
- inserting an electronics housing into the body between the vertical portions of the first and third cartridges and the vertical portions of the third and fourth cartridges.
