Title: IR detector system and method
Inventor: WILSON MARK CLIFFORD
IPC: H04N5/347
Filed: 2009-09-24
Abstract: A system and method of reducing undesirable image artefacts such as image tear and image smearing is described. The system comprises a group of pixels and enhanced sensitivity circuit means. The circuit means are configured so as to operate in an enhanced sensitivity mode and comprise a combination of sample and hold circuit means M21/Ch1 and M22/Ch2 and binning function means M7, in which the sample of a first pixel in the group integrates onto a first sample and hold capacitor Ch1 using combined integration capacitance Cint1 + Cint2 + Ch1, but not onto the other sample and hold capacitor Ch2. The second pixel is then sampled using combined integration capacitance Cint1 + Cint2 + Ch2. An advantage of this approach is that the field capture times are separated only by the stare time (0.6ms) of the first field and reset time of the second field (0.05ms) and reduces smear or multiple images on fast moving targets.

Abstract: 913,804. Reverse gears. TWEEDALES & SMALLEY Ltd. March 15, 1961 [March 21, 1960], No. 10016/60. Class 80 (2). [Also in Group IX] Drive from a constantly-rotating input shaft 9 may pass to an output shaft 8 by one of three paths, the path depending on which of the three electromagnetic clutches 13, 14, 54 is energized. When clutch 13 is energized, the drive passes by belt drive to shaft 101 having a gear 11 thereon to drive a gear 12 on the input side of clutch 13; the drive then passes via bevel gears 141, a worm and wormwheel 15 to the output shaft 8. If 14 is the clutch energized the drive passes from shaft 101 through this clutch, through gear 16 and a reversing gear 161 to the gear 17 and bevel gears 141 as before. An alternative reverse gear is obtained when clutch 34 is energized in which case the drive passes by a belt 44 through this clutch and further belts and pulleys to the disengaged output side of clutch 14. A freewheel may be incorporated at 10 so that the higher reverse gear may be switched in without disengaging clutch 14. In Figs. 2 and 3 a differential arrangement is shown whereby a disc 20 is oscillated in accordance with the motion of a shaft 8 and at the same time rotated relative to its shaft 33 by the rotation of a pick wheel 27 which is picked by a suitable linkage in accordance with the oscillation of the disc 20. The disc 20 is loosely mounted on its shaft 33 on which is also mounted a ratchet-wheel 40 and gear 39 fixed relative to each other but rotatable relative to the shaft, a gear 37 fast upon the shaft, a gear 32 rotatable relative to the shaft and a gear 19 by which the shaft is driven from the shaft 8 via the gear 18; the gear 32 has fixed thereon a stud 34 having a double pinion 36, 38 rotatable together relative to the stud. Motion is passed from gear 19 to disc 20 via gear 37, pinion 36, 38, gear 39 and ratchet-wheel 40 and a pawl 41 mounted on the disc, the disc being biased in one direction by a weighted rod 21 so that rotation from ratchetwheel 40 to disc 20 can be conveyed in either direction. The additional rotation is conveyed from pick 27 through worm and wheel 31 and a further gear to gear 32 which then rotates relative to shaft 33 and gear 37 to induce a rotation in the double pinion and so drive the gear 39 and ratchet-wheel 40.

Abstract: 418,490. Road - traffic signals on vehicles. SCHRODER, P., 27, Adolf Hitlerstrasse, Feuerbach, Stuttgart, Germany. April 3, 1934, No. 10064. Convention date, Nov. 3, 1933. [Class 118 (ii).] The motor M which normally operates the windscreen-wiper W of a motor vehicle is used for operating a make and break device r, u in the circuit of a rear warning light 1 which is automatically illuminated when the brake pedal B or either direction-indicator 4, 5 is operated, whereby a flashing signal is given. As shown the circuit of the motor M may be completed by the closing of the switch 2 controlled by the brake pedal or of the direction-indicator operating switch 3 in either direction, whereby a cam shaft m is rotated to oscillate a bell-crank lever carrying one of the contacts r of the make and break device. The windscreen-wiper may be operated independently of the other controls of the motor by means of a manually controlled switch d in the motor circuit in parallel with the other switches, and this switch is mechanically linked to a rocking plate k, Fig. 2, carrying a train of gearing. When the switch d is closed, the plate is rocked about the motor shaft b to cause a pinion o driven from this shaft to mesh with a toothed wheel y carrying an eccentrically pivoted rack z which engages a pinion z<2> on the wiper shaft z<1>. When the switch d is opened the transmission between o and y is broken, the train driving the cam shaft m for operating the make and break device remains in gear whatever the position of the rocking plate k and such position is independent of the actuation of the switches 2 and 3.

Abstract: 418,633. Rectifying alternating current. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. April 4, 1934, No. 10239. Convention date, April 4, 1933. [Class 38 (ii).] In order to reduce the rate at which short circuit current builds up in rectifiers feeding load circuits having a small time constant, the anodes are subjected to grid control, and the phase of the voltage applied to the grids is retarded in dependence upon the rate of increase of current in the load circuit. In the arrangement shown, chokes 8, normally saturated by windings 8<1> fed with D.C. through a rectifier 9, are included in the supply to the grid transformer 10, and the degree of saturation is decreased in dependence upon the rate of increase of load current by current supplied to windings 8<11> from a current transformer 11 in the cathode lead. A choke may also be included in the cathode lead to assist in retarding the building up of short circuit current. The arrangement is described as particularly applicable to traction systems in which, due to the shortness of feeders on sections near to the substation, short circuits on such sections tend to cause simultaneous release of all the protective devices on the D.C. and A.C. sides and in the anode leads.
