A California dial refers to a clock face that consists of half Roman (usually 10 o'clock to 2 o'clock) and half Arabic numerals (usually 4 o'clock to 8 o'clock). A dash is often used for hours 3, 6, and 9, and an inverted triangle for hour 12. The use of this style dates back to the 1930s, and was featured in early Rolex and Panerai watches. [1]
Ideal test indicator pushed. Prior to modern geared dial mechanisms, test indicators using a single lever or systems of levers were common. The range and precision of these devices were generally inferior to modern dial type units, with a range of 10/1000 inch to 30/1000 inch, and precision of 1/1000 inch being typical.
The radial inclination of a distal radius fracture is shown in red in image at right. The angle is measured between: [4] [5] A line drawn between the distal ends of the articular surface of the radius on an AP view of the wrist. A line that is perpendicular to the diaphysis of the radius. Radial inclination is normally 21-25°. [6]
Package with one tilt indicator. A tilt detector or tilt indicator is a device which indicates whether a tilt has occurred. Tilt detectors can be used on shipments of tilt sensible items to indicate whether a potentially damaging tilt have occurred.

Instead of the radial distance r geographers commonly use altitude above or below some local reference surface (vertical datum), which, for example, may be the mean sea level. When needed, the radial distance can be computed from the altitude by adding the radius of Earth, which is approximately 6,360 ± 11 km (3,952 ± 7 miles).
Measuring the slope angle of a tape or chain during distance measurement. Measuring the height of a building, tree, or other feature using a vertical angle and a distance (determined by taping or pacing), using trigonometry. Measuring the angle of drilling in well logging. Measuring the list of a ship in still water and the roll in rough water.
To measure the radius of a sphere—e.g. the curvature of a lens—the spherometer is leveled and read, then placed on the sphere, adjusted until the four points exert equal pressure, and read again. The difference gives the thickness of that portion of the sphere cut off by a plane passing through the three feet.
