Abstract
One embodiment of an inclinometer is disclosed comprising lines (112) on a sticker (110) applied to a ski pole shaft (210). Each line (112) represents a unique slope angle, and may be identified by a number (114) to indicate the slope angle, such that the lines (112) can be used to visually identify slope angle when the ski pole shaft (210) is held vertically. Slope angle measurements can be taken by sighting a side profile of the slope, or by sighting up or down the slope, or by direct contact measurement with the slope. Other embodiments are described and shown, including one with lines (112a) printed directly onto a ski pole shaft, and one that's applied to the cylindrical surface of a water bottle (910) rather than to that of a ski pole shaft.
Claims20
An inclinometer, comprising:
- (a) a surface of approximately cylindrical or near-cylindrical shape,
- (b) one or more lines on said surface,
- (c) each said line being located at the approximate intersection between said surface and a hypothetical plane at a predetermined angle to the axis of said surface, and
- (d) means of ensuring said axis of said surface is approximately vertical, whereby said line or lines can be used visually to measure or approximate an inclination.
A method of measuring inclination, comprising:
- (a) providing a side view of an incline,
- (b) providing a surface of approximately cylindrical or near-cylindrical shape,
- (d) providing one or more lines on said surface, each said line being located at the approximate intersection between said surface and a hypothetical plane at a predetermined angle to the axis of said surface,
- (e) holding said surface, with said incline in the background, in such a way that said surface's said axis is approximately vertical, and said line or lines slant generally in the same direction as said incline,
- (f) observing the angles of said line or lines in comparison with the angle of said incline in the background,
- whereby the approximate inclination of said incline can be determined by visual comparison with said line or lines.
A method of measuring inclination, comprising:
- (a) providing an observer
- (b) providing an object
- (c) providing a surface of approximately cylindrical or near-cylindrical shape,
- (d) providing one or more lines on said surface, each said line being located at the approximate intersection between said surface and a hypothetical plane at a predetermined angle to the axis of said surface,
- (e) holding said surface between said observer and said object in such a way that said surface's said axis is approximately vertical, and said lines slant generally in the same direction as the line-of-sight between said observer and said object,
- whereby the approximate inclination of the line-of-sight between said observer and said object can be determined by observation of the apparent shape of said lines.
