Abstract: A head-up display system in a military aircraft provides projection of flight and weapon-aiming information into the pilot's line-of-sight through a partially-transparent reflector. The pilot operates a button firstly when he recognizes a target viewing through the display and then again when he fixes his eye on an aiming marker in the display. On each occasion of button operation a measure of his eye position is entered into the system to derive coordinates of the identified target related to the marker position in the display, for generation of the appropriate shifts to move the marker into register with the identified target. The measure of eye position is provided in each case by analysis of video-signal waveforms derived by a vidicon camera that is carried on the pilot's helmet and scans reflection in the helmet-visor of the pilot's eye as illuminated, also by reflection in the visor, from an infra-red source.

A second form of my invention is shown which clips onto the user's regular eyeglasses, and a third form attaches adhesively to the lower portion of regular eyeglasses.

Abstract: Apparatus for estimating the range of a golf course flagstick in terms of a number of paces which is common to all users. An opaque body adapted to be held in the hand is so shaped that its profile has two parallel ridges which face in the same direction, are separated by 47/64 inch, and lie on the same side of a perpendicular line along which they terminate. In use, the apparatus is held at arm's length so that the ridges are horizontal and the lower ridge is aligned with the lowermost visible extremity of the flagstick. In the special case when the upper ridge is found to be in line with the uppermost end of the flagstick the observer is 100 paces from the flagstick. In the general case the distance to the flagstick in relation to 100 of the user's paces then consists in the ratio of the observed distance between the ridges to the observed height of the flagstick.
