Title: A behavioural biometric security system using keystroke metrics
Inventor: SZYMKOWIAK ANDREA
IPC: G06F21/00
Filed: 2009-05-27
Abstract: A behavioral biometric system uses keystroke metrics a way of granting a user access to a system. In use a plurality of test keyboard metrics are generated from a received identity verification request (24). A typing pattern expressed in the test keyboard metrics (26) is then compared with one or more stored keyboard metrics from a plurality of registered users(28). If no match is found the user is refused access (31) otherwise the closest registered user is identified (32). A second comparison(32) of the received keystroke metrics is then made with one or more stored metrics associated with a user in a normally stressed state. Access to the controlled resource is only allowed when a substantial match is found (36). The metrics used may include inter key latency, hold time or typing error. Metrics for a more stressed state of the user may be stored. These may be recorded by manipulating the emotional state of the user using a number of stimuli such as the International Affective Digitized Sounds (IADS) and/or measuring the Galvanic skin response of the user. The system and method may be used as part of an ATM, door entry system or a portable wireless device.

Title: Improvements in or relating to fluid pressure operated brakes for vehicles
IPC: B60T13/46
Filed: 1945-04-21
Abstract: 630,126. Fluid-pressure-operated brakes. BENDIX AVIATION CORPORATION. April 21, 1945, No. 10095. Convention date, Aug. 18, 1944. [Class 103 (i)] A relay valve for controlling the brakes on a trailer vehicle and which in an application of the brakes is adapted to give a pressure differential in the trailer brake cylinder which initially is high relatively to that in the tractor brake cylinder but gradually becomes substantially equal thereto when the maximum pressure differential is reached, comprises in addition to diaphragms subject to cylinder and control pipe pressures, a diaphragm, the pressure difference acting on which is normally zero, is suddenly raised to a maximum by an auxiliary valve actuated by control pipe pressure at the initiation of a brake application and thereafter falls gradually to zero again. A system is shown in which the brake cylinders of the tractor and trailer are vacuum and atmosphere suspended respectively and are controlled by a common main valve to which the tractor cylinder is directly connected. A control pipe extends from the main valve on the tractor to the relay valve on the trailer and a second pipe extends from the engine suction pipe to a vacuum reservoir on the trailer: Fig. 3 shows the trailer relay valve in brakes-applied position, the vacuum reservoir connection 36 being in communication with the brake cylinder connection 38 which is isolated from the atmosphere connection 42 by the closed valve 54. The valves 54, 56 are controlled by the diaphragm 62 which is under the forces of a spring 76, vacuum in the chamber 66 maintained by the passage 74 and the varying pressure in the chamber 68 which is connected to the main valve on tractor and to that chamber of the tractor brake cylinder, the pressure in which is varied to operate the brakes. In order to obtain a quick response to the initial slight rise in pressure in the control valve, admitted at the connection 40, a slide valve 94, 96 is arranged to move against the action of a weak spring 102 into the position shown in which the atmosphere port 108 is closed and the chamber 82 is connected to vacuum through passages 88, 106. This produces a lifting of the rod 70 in advance of what could be expected if the diaphragm 62 alone had to overcome the internal resistance of the relay valve, and the initial pressure differential in the trailer brake cylinder is correspondingly high. As the pressure in the chamber 48 falls as the brake-application progresses, the pressure in the chamber 84, connected thereto by a channel 86, falls correspondingly and the action of the diaphragm 98 is progressively reduced to zero. The space containing the spring 102 is connected to vacuum by the port 104.

Title: Improvements in or relating to gaskets and their manufacture
Inventor: FARNAM ROBERT G
IPC: F16J15/12
Filed: 1970-03-03
Abstract: 1,272,523. Seals. F. D. FARNAM CORP. 3 March, 1970 [3 March, 1969], No. 10111/70. Heading F2B. A gasket is formed by bonding gasket stock 18, 20 to a metal core 16, the core and gasket stocks being treated for adhesive bonding prior to bonding together by an adhesive layer no thicker than 0À001 inch extending substantially over the entire mating area. The gasket stock may be coated with a bond forming material 22, 24 and attached to at least one side of the core 16 before or after die cutting to a required gasket configuration. A cold rolled steel core may be degreased and coated with a 0À0002- 0-0003 inch layer of curable neoprene and phenolic resin emulsion, the gasket layer, e.g. of asbestos or vegetable fibres, being coated with a natural or synthetic rubber compound. The coatings may then be dried and partially cured prior to joining of webs of the core and gasket materials by passage between pressure rollers, Fig. 9 (not shown), the core web (27) being fed through a preheater at 275-300 F., while passage of the united web through a further heater effects final curing of the adhesive bond. Die cutting and/or stamping then produces gaskets from the web. Alternatively, Fig. 10, precut core and gasket stock portions may be assembled on a stacking platform 48, vacuum heads such as 52, 56 transferring the portions in turn from stacks 41, 42 of respective similar portions to build up a stack corresponding to a series of gaskets interleaved by non-adhesive sheets; pins 50 ensure correct location. The stack is then preheated to 150-180 F. and hydraulically pressed at 500-1000 p.s.i./325-350 F., momentary release of the pressure during the cycle allowing escape of volatile components. As a further alternative, Fig. 11 and Figs. 12-13 (not shown), a three-piece gasket may be assembled from pre-cut portions on an indexing table 60. An operator at a station A positions a gasket stock portion on a heated pinmould assembly (68), a steel core plate from a preheater 73 being superimposed at a station B, while a second gasket portion is added at station C. Pressure sufficient to ensure intimate contact of the portions is applied at station D, followed by a gasket-forming pressure of about 1000 p.s.i. at station F after passage of the portions through a heater 82. The pressed gasket is ejected at H by a pin mould assembly stripper plate (80) and passed through a conveyerized oven 94 for curing.

In order to reduce relative movement between the engaging surfaces of a friction clutch when disengaged or partially engaged, annular friction discs 34, 42 are rotatably mounted by bearings 32, 40 on eccentrics 30, 38 fast with a driven shaft 14, and are engageable by annular members 68a-68d concentric with a driving housing 46, the member 68d being fast with the housing and the members 68a-68c being connected for rotation with the housing by pins 55, 69 on which they are axially slidable. The discs 34, 42 carry friction facing material and are twice the radial width of the members 68a- 68d. When the clutch is disengaged the discs are freely rotatable on their eccentrics thus reducing idle drag to a very low value. Coolant is supplied by an input driven pump 59 to the interior of the housing 46 whence it flows through a port 77 to a sump 73 formed in a stationary easing 16. The clutch is engaged by pressure supplied by the pump to a chamber 54 of an annular piston 52. The mechanism may be adapted for use as a brake.

Abstract: 576,356. Gyroscopic apparatus. MEREDITH, F. W., GARDNER, G. W. H., and MARSHALL, F. F. April 7, 1936, No. 10257. [Class 97 (iii)] [Also in Groups XXIX and XXXV] An automatic pilot for an aircraft comprises a gyroscope rotor universally mounted upon a frame carrying an elevator control valve or switch and adjustable about an horizontal axis to change the pitch attitude of the aircraft through a servometer operated by the valve and associated with follow-up means. Combined with the pilot is a weight control or accelerometer for regulating the equilibrium pitch attitude of the rotor, axis, the purpose of which is to enable the pilot manually to effect a quicker change in pitch attitude than would be achieved automatically by the pilot. As shown in Fig. 1, the rotor 1 is mounted in the pitch ring 4 with its axis 2 in the fore-and-aft direction of the aircraft and tilted relatively to the line of flight X-X, and the pitch ring 4 is mounted in the azimuth ring 6 which is mounted in a frame 8 tiltable about an horizontal axis 9 and rotatably mounted in a fixed ring 38. The equilibrium pitch attitude of the rotor 1 is controlled by an accelerometer comprising weights 27, 28 interconnected by a link 36 and respectively adjustably mounted on a projection on the azimuth ring and the free end of a' member 29 pivotably supported at its other end in a bearing standard 31 carried by the frame 8 and adjustable about an horizontal axis 32. The pitch ring is connected through linkage to a piston valve 11 in a slidable housing 14 forming part of the follow-up means and having an air inlet 12 and outlets 13 connected by flexible tubes to the opposite ends of a servomotor 17, the piston 18 of which controls through cables 19, 20 the elevators of the aircraft and, through a rack and pinion 21, cables 23 and a pulley 24 carrying an adjustable eccentric 25 having an arm 26, the position of the housing 14. When the pilot wishes to effect a quick change in pitch attitude of the aircraft, he turns the handle 34 so as to rotate the frame 8 in the ring 33 and effect relative displacement of the valve 11 and the housing 14 and consequent operation of the servometer. The gyroscope may be employed also to control the rudder of the aircraft, and the valve may be replaced by a switch for controlling an electric servomotor.
