Title: Automatic system for displaying and exploiting data pertaining to vehicles passing predetermined points
IPC: G08G1/123
Filed: 1973-05-24
Abstract: 1438183 Electric selective signalling; roadtraffic signals THOMSON-CSF 24 May 1973 [26 May 1972] 25004/70 Headings G4H and G4Q The invention relates to a system for presenting and utilizing data pertaining to vehicles (e.g. buses) at predetermined transit points along a route defined thereby (e.g. bus stops). At a bus stop, frequency-, phase-, or amplitude-modulated radio signals are received and demodulated 1-3 and passed to series/parallel registers 4 where they are checked for parity. The outputs 5-9 from 4 indicate respectively: message valid, bus identity number, vehicle occupancy, distance Dv from a datum point, e.g. start of route, and direction of travel. Signals 5-7 pass to a storage unit 14, Fig. 3 (not shown), which incorporates appropriate gating circuitry. Signal 8 and a signal Ds (distance of bus stop from start of route) are fed to a subtractor 12 which sends signals 20 (De = Ds - Dv) and 22 (sign of De) to 14. Signal 9 is fed to a comparator 10 to check that it is going in the right direction for the bus stop (output 18). Store 14 is linked via a code converter 15 to a display 16 (luminescent, liquid crystal, &c.) which indicates, inter alia, the distance De of the bus from the bus stop and the number of unoccupied seats thereon. If several routes pass the same bus stop, the system will include separate items 10-16 for each route, the comparators 10 being used to discriminate between the different routes. The system may be adapted to control traffic lights when a bus is within a "zone of action" (distance Da) thereof. At each set of traffic lights, Fig. 5, signals De, Da from subtractor 12 and a store 56 are compared at 55: if De<Da and if De>0, a gate 54 is enabled. This enables a gate 57 which passes the vehicle number 6 to a store 49 if this is empty (determined by logic 48-52) and if the received message is correct in other respects (gate 23 and comparator 50). A signal 53 indicating that 49 is not empty is then used to control the traffic lights. The system may be adapted by suitable duplication of components to deal with several buses within the "zone of action" and/or several routes passing the traffic lights.

Title: Improvements in xerographic image projection
IPC: G03G9/16
Filed: 1963-06-26
Abstract: 1,034,097. Xerographic projection apparatus. RANK XEROX Ltd. June 26,1963 [July 2, 1962], No.25396/63. Headings G2H and G2J. In image projecting apparatus a collimated beam of light from lamp 21 is selectively internally reflected in glass prism 20 in conformity with an image formed in relief either on the internally reflecting surface or on a transparent sheet in contact with it, the internally reflected light then being focused by lens 23 on to viewing screen 24. The relief image is formed xerographically by means of plate 30 comprising a photoconductive insulating layer 32 on a glass sheet 31 having a transparent conductive layer. Plate 30 is electrostatically charged and exposed to a projected light image from system 38 and droplets from atomizers 33 are charged at 34 and 35 sprayed into the space between the prism and plate 30 under the influence of a controlling electric field between plate 30 and a transparent conductive coating on the prism surface. A droplet image is formed on plate 30 and on the prism, the prism image being projected as above. The liquid may be opaque, dyed or pigmented. In Fig.4 (not shown), transparent layer 37 is coated with a transparent insulating layer 40 which may be a liquid such as oil, or a thermoplastic such as styrene, acrytic, polyethylene, or cellulose resins. When thermoplastic layer 40 is softened by electrical heating and is deformed imagewise by the closely adjacent latent electrostatic image on plate 30. Coating fixes the image for projection as above. Further heating removes the image when plate 30 is removed. A very thin oil layer 40 may be similar by distorted imagewise and is persistent for projection. A permanent image may be produced by heating if a heat-or photo-polymerizable liquid is used. Examples given. If layer 40 is itself a deformable photoconductive material, coated on to layer 37, then plate 30 is unnecessary, and the latent image is formed directly on layer 40. In Fig. 5 (not shown), a deformation image is formed as above on a transparent flexible thermoplastic web 50 of say, polyethylene terephthalate polyester film with a conductive layer, which is moved continuously or intermittently over the prism surface for projection, optical contact being assisted by an oil coating. Lamp 54 erases previous images. Alternatively, the moving transparent web may receive a droplet image as described above. In Fig. 6 (not shown) an image of a cathode ray tube 71 is focused on to a rotating xerographic drum 70 and the latent electrostatic image then passes close to a liquid film 40 on the prism face, and the film is continuously distorted imagewise for projection as above.
