Title: Radiation sensitive scanning system
IPC: G06V10/12
Filed: 1973-12-05
Abstract: 1403313 Copying by scanning INTERNATIONAL BUSINESS MACHINES CORP 5 Dec 1973 [18 Dec 1972] 56411/73 Heading H4F A document scanning system includes means for compensating for illumination variations and for variations in the sensitivities of the individual diodes of a photodiode array 15 viewing a document 10; a white portion of the document 10 is initially scanned, the output signals from the different diodes being, after processing at 25, 30, stored in a background store 50, and also being fed to a data store 45; when the information portion of the document 10 is scanned the serial output signals are fed, via 25 and 30, to input buffer 35, each output signal together with the signal stored in background store 50 relating to the respective photodiode being used to address data store 45 and to derive therefrom a signal which is independent of photodiode sensitivity and illumination variances. Data store 45 may, for example, store contrast ratios equal to (background signal-information signal)/ (background signal). In a second embodiment (Fig. 4, not shown) coherent noise such as photodiode leakage current and clock noise is also compensated. In this embodiment signals are derived from the photodiodes when light is blocked off from the array 15 or the array scans a non-reflective black background; these signals are then fed to a black level store (75) and a further data store (70), subsequently derived signals being used, together with the signals in the black level store (75) to address the further data store (70) to derive noise-free output signals. Operation then continues as for Fig. 1, the background signals and information signals fed to stores 45, 50 being signals from which noise has been removed. In this embodiment background store 50 is also updated when a compare circuit (80) detects a noise-free information signal fed to data store 45 as being greater than a predetermined grey level. To minimize the number of bits required from A/D converter 30 its reference voltage may be controlled either by a signal proportional to the average document reflectivity derived from a phototransistor (17, Fig. 4, not shown) or by a signal proportional to the average data in background store 50.

Title: Gyroscopic instrument for facilitating observations with optical aiming or observation devices
Inventor: BEZU MAURICE
IPC: G02B27/64
Filed: 1969-12-11
Abstract: 1,269,817. Sights. M. BEZU. 11 Dec., 1969, No. 60473/69. Heading F3C. [Also in Division G1] The optical beam 13 of an aiming or viewing device, e.g. a borosight is stabilized by a gyroscope 1 having a rotor 2 rotatable about an axis 3 in an elevation gimbal 5 in turn rotatable about an axis 6 in an azimuth gimbal 7 free to rotate about a vertical axis 8 in the body 9 of the device, the optical system of the device including a mirror 12 mounted on the gimbal 7 for rotation about an axis 11 parallel to the axis 6, the mirror being stabilized by the gyroscope 1 against unwanted movements of the body 9 e.g. movements due to its mounting on board a moving craft, to compensate the optical beam 13 of the device, so that its direction remains fixed in space. The gyroscope rotor axis 3 provides an attitude reference for the boresight, which due to the mounting of the mirror 12 remains aligned with the axis 3 in azimuth. Relative movement of the body 9 of the device and rotor 2 in elevation cause rotation of the gimbal 5 about the axis 6 and these movements are communicated to the mirror 12 by pulleys 15, 14 and an interconnecting metal strip 16 so that the mirror 12 moves through half the angle of movement of the gimbal 5. A tracking gimbal 17 is slaved to the movements of the azimuth gimbal 7 by means of a deviation sensor 42, amplifier 18, motor 19 and gearing 20. Potentiometers 21, 22 provide readouts of the position of the rotor axis 3 with reference to the body 9 in azimuth and elevation respectively. When it is desired to traverse the foresight in elevation in seeking a target, a manually operated potentiometer 23 is used to apply voltage to a torquer 25 to rotate the azimuth gimbal 7 in one direction or the other as desired. For high speed traverse a switch 24 is used to feed the maximum potentiometer voltage to the torquer 25. For traverse of the boresight in azimuth a potentiometer 26 is provided this controlling a torquer 27 causing rotation of the elevation gimbal. For high speed traverse in azimuth switch 28 is operated to apply a voltage through amplifier 18 to motor 19. This rotates the gimbal 17 and through the provision of a clevis 32, the gimbal 7. During this movement a relay 29 also operated by the switch 28, cuts off the supply to an electromagnet 30, the core of which engages a notch in a sector 31 on the gimbal 5 and prevents movement of the gyroscope and mirror 12 in elevation. A system is also described in which two such devices as described above may be slaved for movement one with the other or operated independently if desired.
