Patent GB-2317526-A (GB)
Title: Offset noise cancelation in an array of active pixelimage sensors
Inventor: HURWITZ JONATHAN EPHRIAM DAVID
IPC: H04N5/365
Filed: 1997-09-12
Abstract: With switch S3 open light is allowed to fall on the sensor array, generating an image signal in the pixels 2 of the array. While the image signal is incident on the array the first S1 and second S2 switches are closed thus holding the first terminal 13 of C2 at voltage Vref. C1 charges to the combined output signal(Vreset - Vsig - Voff) from the active pixel where Vsig is the image signal to be detected, Vreset is a fixed pixel reset potential and Voff being a voltage offset from the active electronic circuitry in the pixel 2(Voff varies randomly from pixel to pixel). Next, the second switch S2 is opened, removing the voltage clamp on C2, and the pixels in a chosen row are reset via MOS switch X. Now the pixel output 4 contains only the offset reset value, Vreset - Voff. As C2 is in series with C1 the potential on node 13 of C2 will change by: Vsig . (C1/(C1+C2)) and the total signal stored on C2 is: V2=Alpha. Vsig + Vref where Alpha is an attenuation factor and Vref is common to all capacitors C2. V2 is subsequently read out from C2 by closing the third switch S3 to connect the first terminal 13 of C2 to the output bus 17. As the offset signal Voff has been cancelled in the total signal V2 on C2, a fixed-offset-corrected pixel output Vout=V2 for the pixel 2 can thus be read directly from C2. This is done for each pixel in the nominated row of pixels. The process is then repeated for each row to produce a complete image from all the pixels in the array.

Title: Single lens reflex camera having a preview function
Inventor: OGI MIKIO
IPC: G03B9/02
Filed: 1997-11-14
Abstract: A method for controlling a single lens reflex camera having a preview function is provided in which a mirror drive mechanism 20, a diaphragm drive mechanism, and a shutter are driven in association with the rotation of a single-revolution cam gear 25, 26 is driven by a motor 12. When the release switch is turned ON, the single-revolution cam gear is rotated by a single revolution in the forward direction, and when an external preview switch is turned ON, the preview operation is carried out by the reverse rotation of the single-revolution cam gear within a predetermined angle range in which the stop-down operation takes place without causing an upward movement of the mirror 55. When the release switch is turned ON during the preview operation, the motor is rotated in the forward direction until the single revolution cam gear is returned to the initial position, so that the photometering operation is carried out at the full-open aperture position.

Title: Mechanical vapour recompression separation process
Inventor: RAZZAGHI MINOO
IPC: B01D3/32
Filed: 1998-05-14
Abstract: There is disclosed a method and apparatus for removing a contaminant from a fluid feed stream containing the contaminant. The method includes the steps of providing a feed stream and heating it in a first step to at least partially remove some of the contaminants and recover energy from a concentrate and distillate generated. Further heating the feed stream in a second heating step in a heated separator generates a saturated vapour fraction and a concentrated liquid contaminant fraction. The vapour fraction may be compressed to generate a temperature differential in the reboiler exchanger with the vapour fraction being passed into contact with a reboiler exchanger to provide a stream of condensed vapour from the reboiler. The stream may be circulated through the reboiler exchanger and the heated separator to maintain from about 1% to about 50% by mass vapour in the stream. The apparatus includes a unique configuration of a vapour compressor, heated separator in combination with a forced circulation circuit to generate the decontamination result.

Title: Rechargeable battery
Inventor: SEOK CHAN-BOK
IPC: H01M50/55
Filed: 1999-08-03
Abstract: A rechargeable battery, designed to allow a user to easily and simply recharge a battery without having any separate electric cord or plug, is disclosed. The battery is integrated with a recharging unit within a casing and is provided with a power connection means for electrically connecting the recharging unit to an external power source. The power connection means consists of two plug terminals 50, 51 and one thumb-operable guide terminal 52. The three terminals are held on three rotatable shafts within the casing in a way such that they are normally positioned at a fully laid and retracted position within the casing and are selectively rotated from the retracted position to an upright position through three slits of the casing. In order to allow the two plug terminals to be rotated in conjunction with a levered action of the guide terminal, three pinion gears are respectively formed on the three shafts of the terminals. A rack engages with the three pinion gears, thus allowing the three pinion gears to be rotatable in the same direction at the same time.
