Electronic level with display scale and audible tone scale

An inclination sensor device comprising:

• a sensor for determining an inclination of the device relative to a null inclination;
• and
• an audible tone generator for generating musically scaled audible tones, one of the tones being generated for one or more of a plurality of determined inclinations of the device;
• wherein the tones are in sequential association with increasing determined inclination, and wherein during changing of the inclination of the device the tone generator provides a plurality of the tones in sequence of the musical scale.

An inclination sensing device comprising:

• a plurality of sensor elements, each sensing capacitance changes in response to inclination;
• a comparator associated with each sensor element for detecting a voltage of each sensor element in response to an excitation cycle of said sensor element;
• a first digital to analog converter for supplying a first reference voltage to certain of the comparators;
• a second digital to analog converter for supplying a second reference voltage to a remainder of the comparators;
• and
• signal processor circuitry for determining and displaying the inclination in response to output signals of the comparators, the signal processor circuitry averaging the output signals of the comparator over a predetermined number of the excitation cycles.

An inclination sensor device comprising:

• a sensor for determining an inclination of the device relative to a null inclination;
• and
• a visual display for displaying the determined inclination, the visual display comprising a plurality of illuminated parallel and adjacent line segments, each line segment representing a predetermined increment of inclination expressed as a linear deviation per linear distance, a particular number of line segments being displayed for each said determined inclination;
• wherein each fourth line segment is longer than are adjacent segments.
