Title: Vehicle having a transmission locking system
IPC: F16H61/18
Filed: 1974-12-24
Abstract: 1489899 Transmission locking safety devices NISSAN MOTOR CO Ltd 24 Dec 1974 [24 Dec 1973] 55684/74 Heading B7H A safety system for a vehicle, particularly an automatic transmission vehicle, includes means for locking the gear selector lever in "neutral" or "parking" until the occupants have carried out certain precautions such as fastening the seat belts. The selector lever (Fig. 1, not shown) carries a plate having holes engageable by an electromagnetically actuated pin when the lever is in the "neutral" or "parking" position. The pin is actuated by a circuit when it detects the seating and belt fastening of the occupant. A circuit 56 for the starter motor 80 includes switches 64, 66 which are respectively closed when "neutral" or "parking" is engaged thus preventing engine start in any other gear position. A transmission locking circuit includes a seat switch 82 which closes to produce a signal A when an occupant sits. Switch 82 is in series with a switch 86 which is closed when the driver fails to carry out the precautionary procedure and produces, when closed, a signal B. A failure detecting circuit 92 produces a signal G when the signal B or F is present at OR gate 106, the signal F only being present when A and E are present at the AND gate 104. A vehicle speed sensor 108 produces a signal H which is applied to a NOT circuit 109 that gives a signal I when the vehicle is not moving. When I and G are applied to the AND gate 107, that is when the vehicle is stopped and the precautions have not been effected, a signal J actuates the solenoid 42 controlling the pin to lock the gear selector.

Title: Method and system for centroidal tv trackings
IPC: G05D3/00
Filed: 1972-12-18
Abstract: 1358619 Optical tracking WESTINGHOUSE ELECTRIC CORP 18 Dec 1972 [21 Jan 1972] 58327/72 Heading H4D Digital techniques are employed to locate and track the centroid of a target image produced by TV scanning techniques. The TV video signal is processed for changes in level, corresponding to contrast differences between the image and the background, and all level changes are stored digitally with co-ordinate information related to vertical and horizontal positions. Each level change is weighted as a function of displacement from the co-ordinate axes, and summed each scan frame to yield the mean of all level changes recorded. The image of the target is tracked by sensing digitally the change of position of its centroid in subsequent TV frames, and providing positioning information to the TV camera tracking servomechanism, so as to centre the image on the TV display. As described, the TV image is processed electronically by employing a basic structure of multiple grids overlayed by time-gating on the TV video signal. A coarse grid of N x N data cells covers the display (Fig. 1, not shown), and a smaller array of M x M cells determines a track window (Fig. 2). Each cell within the track window is further sub-divided into 2<SP>2P</SP> cells, P being an integer, which each contain the smallest quantum of resolution. Initially, the track window is positioned over the target image by manually operated control means. The video display signal is filtered, delay line differentiated and full wave rectified (Fig. 3, not shown). The video signal is processed for horizontal information by time gating a given TV scan line and for vertical information by comparing adjacent scan lines at the same horizontal positions. If the amplitude of the video signal changes within a cell according to a selected signal transition, that cell is assigned a "mass" of one; otherwise the cell is assigned a mass of zero. Each cell given a mass of one is further weighted in assignment according to the occurrence of the particular transition within the aforementioned multiple grid structure. For each TV frame scanned within the track window a summation is made of all cell masses, and the sum is divided by the number of cells having masses greater than zero. In the target image shown in Fig. 4, mass points 1 to 8 and 10 to 18 have all resulted from horizontal transitions, indicated by darkening of the smallest quantum step, or sub-division, of the data cell in which the transition occurred. Mass points 9 and 10 have resulted from vertical only detections. The shifting of the pattern by one sub-unit to the right and by one sub-unit down is to simulate the effects of the delay line differentiator in the horizontal processing and the line to line comparisons in the vertical processing. When given weighting rules are applied, the target image centroid is computed to fall in the centre of the track window. Digital circuitry for implementing the invention is described with reference to Fig. 6.
