Title: Vehicle anti-glare and wide visibility rearview mirror
Inventor: KANAZAWA TORU
IPC: B60R1/08
Filed: 1996-01-16
Abstract: A rearview mirror comprises a transparent electrode film (21), an electrochromic (EC) layer (22) of an optoelectronic element, a reflecting electrode film (23) and an insulating sealing film (24) which are deposited on the rear surface of a transparent substrate (20). The transparent substrate (20) has dividing lines (15, 16) for dividing the mirror surface into a main convex mirror surface area (11), and a supplemental convex mirror surface area (12) of a gradually decreasing radius of curvature. The EC layer (22) and the reflecting film (23) are divided along the dividing line (16) by cutting the transparent electrode (21) so that the reflectivity can be independently controlled in each area (11, 12). As alternatives to the EC layer (22), a transparent ferroelectric thin film or an electroluminescence layer may be applied to the supplemental area (12).

Title: Luggage scanner
Inventor: BENJAMIN RALPH
IPC: G01V5/00
Filed: 1996-07-18
Abstract: A screening system for screening items, such as aircraft-hold luggage, uses a conveyer system for carrying the items along a path and an array of sensors (each sensor comprising a radiation source, e.g. an x-ray source, and a radiation detector disposed upon opposite sides of the said path) spaced along and around the path for determining the opacity to radiation in planes intersecting the path and the items. A signal processor uses signals from the sensors to detect contours of maximum local rate of change in opacity and from these reconstruct boundaries between the regions having different opacity to radiation and then determines whether or not one or more predetermined screening criteria, e.g. an opacity falling within a predetermined range of opacities, are met.

Title: Seat contour adjustment mechanism
Inventor: DECEUNINCK STEFAAN
IPC: A47C7/46
Filed: 1996-08-23
Abstract: A seat contour adjustment mechanism comprises a cam element 17 attached to, for example, a Bowden cable (9, fig 1) so that as the cam 17 is rotated by means of rotatory shaft 10A the cable is wound upon the cam 17. A surface of the cam 17 is of varying radius with respect to the axis of the shaft 10A so that mechanical advantage between the shaft 10A and the cable varies as the shaft 10A is turned. This mechanical advantage allows the adjustment mechanism to progressively increase the force on the Bowden cable which is necessary to move side rails, in the seats lumber support, from a first position to a second position (see figs 2 and 3). So as to retain the cam element in a set position a friction clutch comprising a spring 22 and a clutch housing 23 is provided.

Title: An inflatable packer
Inventor: APPLETON ROBERT PATRICK
IPC: E21B33/127
Filed: 1997-02-03
Abstract: A hydraulic packer comprises a mandrel 2 and an external cylinder 38 upon which is mounted an inflatable elastomer sleeve 44. The adhesive bond between the ends of the sleeve and the cylinder is reinforced by spring bars 47. The sleeve is inflated when a drop ball is located in the seat 60 provided on the piston 56. The fluid which passed through the bore 58 then flows into the sleeve through the aligned inflate ports 34, 70 until a predetermined pressure is reached when the shear pins 80, which support the piston, break and the piston descends thus misaligning the inflate ports and trapping the fluid within the sleeve. The piston motion may cause the packer to be released from the well bore string (from 18 upwards). Serrated metallic gripping elements (not shown) may be provided on the exterior of the inflatable sleeve in order to anchor the packer within the well bore.

Title: Viterbi decoder having a variable number of states
Inventor: KOIZUMI FUMIAKI
IPC: H03M13/23
Filed: 1998-06-05
Abstract: A Viterbi decoder includes means for varying the number of states based on channel quality. The magnitude and delay quantity of the delay wave contained in a received signal are determined, and using an estimate of the channel quality the necessary number of states is determined. The channel quality or state is obtained by estimating the imputse response of the channel. In this way, when the transmission quality of the channel is good, the level of computation performed by the decoder is reduced thereby reducing power consumption and increasing the processing speed of the decoder. Application is to decoders in portable radio telephones.

Title: Regulating pressure in a common-rail fuel injection system
Inventor: HARTKE ANDREAS
IPC: F02D41/24
Filed: 1998-11-24
Abstract: Fuel supply to the system 32 is controlled by electrically adjusting a throttle valve 4 for high-pressure pump (5, Fig 1), by adjusting the pump itself and/or by adjusting a low-pressure feed pump (2). Control signal V for these devices is derived in regulating block 31 from engine speed N and fuel amount MF which is based on driver demand, eg accelerator pedal travel. Corrections and limitations are applied based on sensed actual fuel pressure FUP, leakages 41, coolant temperature TCO, battery voltage VB, desired fuel pressure FUPS and overloading current 52. Control of pressure regulating valve 6 which releases fuel pressure in the rail to the fuel tank can also be implemented based on actual and desired rail pressures FUP, FUPS and engine speed N in block 30. Limitations due to temperature TCO battery voltage and engine state ES can be applied here too. Desired pressure FUPS is calculated from N, TCO and MF by unit 56.

The blend is preferably in the form of a water-in-oil emulsion. which can be prepared by mixing separate water-in-oil emulsions of the two polymers. Preferred polymers are for example acrylamide/quaternised dimethyl aminoethyl acrylate copolymers. The structured nature of the first polymer may be introduced by including for example N,N'-methylenebisacrylamide in the monomers used to produce it.
