Title: Pattern counting system using line scanning
IPC: G06T7/00
Filed: 1974-12-24
Abstract: 1498630 Counting patterns; image analysing NIPPON KOGAKU KK 24 Dec 1974 [28 Dec 1973] 55669/74 Heading G4D The invention provides a logic circuit for "filling in" misleading cavities in the digital image to ensure accurate counting of objects in a line-scanning image analyser. The signal S from the scanner, which may be a television camera, after passing through a thresholding circuit is fed into a shift register SRI which has a number of stages and is stepped at a clock frequency such that it contains one complete line scan at a time. The logic circuit transfers the contents of SR1 to a second register SR3 after filling in the cavities Q of the image; the contents of SR3 are also entered into a third register SR2 one line period later. The contents of SR3 and SR2 are serially read out to a counting circuit CO employing the usual anticoincidence circuits to detect the end of each object. The logic circuit employs a plurality of identical cells C (Fig. 3) each cell operating to enter a bit in a respective stage of the M register if either there is a bit in that stage of the S register or there are signals R, L propagating from both the cells to the left and right thereof. The propagating signals are present if a bit was entered in the M register on the last line scan and there is either a bit in the adjacent stage of the S register or a signal propagating from the next but one. An alternative circuit (Fig. 6, not shown) employs random access memories instead of the shift registers and operates in a different manner.

Abstract: 1,161,248. Semi-conductor devices. BROWN, BOVERI & CO. Ltd. 20 Dec., 1966 [22 Dec., 1965], No. 56949/66. Heading H1K. A semi-conductor device comprises two elements having electrodes on their opposite faces joined together in abutting relationship to form a series connection, one of the elements having a PNPN structure with both of the outer junctions short-circuited by the electrodes and having a control electrode connected to one inner zone. As shown, Fig. 2, the PNPN structure is produced by diffusing an acceptor into an N- type wafer 1 to produce a P-type region 2, and alloying grid-like foils to the major faces to form P-type region 3 and N-type region 4. Layers (12, 13) of metal are vapour deposited over each of the faces to short-circuit regions 1 and 3 on one face and regions 2 and 4 on the other face, Fig. 3 (not shown). Main electrodes 5, 6 are soldered to the faces, the disc is formed into a frusto-conical shape, and a control electrode is welded to region 2. The resulting element has a normal SCR switching characteristic in the forward direction but is conductive in the reverse direction due to the short-circuits across the outer junctions, Fig. 4 (not shown). Two such devices may be mounted back-toback to provide a bi-directional switching device. Figs. 5 and 6 (not shown), and one device may be connected in series with a similarly poled junction rectifier which determines the reverse chracteristics of the composite device, Figs. 7 and 8 (not shown).

Lateral deflections of the working member are cushioned by pistons 26 movable in cylinders against gas therein. The resilient coupling comprises resilient members 25 on either side of a member 22 rigidly connected with the rod. An annular member 20 carrying a sealing ring 21 is movable normal to the cylinder axis in a groove 19 to accommodate angular deflection of the rod. Compressed gas is contained in a plurality of cylinders 7 which via passages 5 are in constant communication with chamber 3 and with a cylinder 53. A fluid pressure pump 9 supplies fluid so that when a valve sleeve 11 is in the position illustrated, fluid in chamber 4 acts on piston 2 to force the piston on a return stroke. Engagement of the piston with projection 51 of a movable member 50 will cause via linkage 49, 58 and 59 movement of the valve sleeve 11 so as to open chamber 4 to exhaust. Thus pressure of fluid within that chamber drops and the piston is driven on its working stroke by gas pressure in the cylinders 7. Outflow of fluid from the chamber 4 during the working stroke forces the valve sleeve 11 to a position in which the ports 10 are fully open to exhaust. When the implement 14 impacts a workpiece, the valve 11 will be returned to the illustrated condition by gas acting on piston 52, and the piston 2 may be cushioned if its working stroke exceeds a predetermined length by part 35 entering space 34. In an alternative embodiment (Fig. 2, not shown) the piston (2) is slidable within a sleeve (36) closed at one end, the sleeve wall at the open end of the sleeve being tapered and provided with notches (33). The sleeve is slidable relative to and within the cylinder so that when the piston overtravels the ports 10 are initially closed by the sleeve which then reverses its movement to open the ports 10.
