Title: Accelerating cold and hot starting of a discharge lamp
Inventor: YAMASHITA MASAYASU
IPC: H05B41/392
Filed: 1995-08-24
Abstract: A discharge lamp 8, particularly a metal halide lamp in a vehicle, is powered from a supply 2 via a DC/DC converter 5 and a DC/AC converter 6 and after starting is controlled at constant power by means of a current and voltage detector 11, a steady power controller 14 and a pulse width modulator 15 acting on the DC/DC converter 5. In order to shorten the time required for the light output from the lamp 8 to become stable, PWM 15 is also under the control of first and second lighting acceleration controllers 12, 13. The first lighting acceleration controller 12 overrides the steady power controller 14 during cold starting to supply an increased current or power to the lamp 8. During hot restart, the second lighting acceleration controller 13 overrides both the controllers 12, 14 to increase the current or power supplied to the lamp 8. The controller 13 has a detector for providing a signal indicative of the light-OFF period of the lamp and operates so that the longer the light-OFF period, the greater is the increase in current or power, and the longer is the time for which the controller 13 overrides the controller 12. If the light-OFF period increases to a certain level, the first lighting acceleration controller 12 resumes control (Figs. 7-11). <IMAGE>

Title: Video signal interpolation including narrow-vector and wide-vector correlations
Inventor: KIM YEONG-TAEG
IPC: H04N7/01
Filed: 1996-09-27
Abstract: Interpolating lines of pixel data in an interlaced-to-progressive scan conversion operation is effected using vertical correlation values Dv and the minimum values Dn (and Dw,Fig 6) of the weighted norms of narrow-vectors and of the wide-vectors respectively, the wide-vectors being derived from a greater number of adjoining pixels in the adjacent lines to the pixel being interpolated than the number of adjoining pixels used to derive the narrow-vectors. The correlation and minimum values from correlator 20 are compared with respective predetermined values Tv,Tn (and Tw) in selector 60 to thereby determine whether a pixel interpolated from vertically adjacent pixels 50 or from pixels determined from the narrow-vector information 40 or wide-vector information 30 is outputted. This interpolation method efficiently interpolates edges having various slopes including gentle slopes, and compensates for high frequency components such as bidirectional edges.

Title: Removable memory device for a portable terminal
Inventor: SAKAJIRI NORIYASU
IPC: H04W92/08
Filed: 1998-03-03
Abstract: A memory device 1 includes a memory 5 for storing individual information, a memory manager 6 for protecting the memory when it is removed from the portable terminal, a data I/O port 4 and a controller 3 for detecting connection of the memory device to a portable terminal and for controlling the memory manager. Before removing the memory from the terminal, a command must be sent, via either the terminal or a personal computer connected thereto, to the memory device and subsequently verified by entering a password. Successful verification causes the memory manager to protect the memory from erasure upon its removal from the terminal. The protected memory can then be inserted into another terminal and, following successful entry of a password, accessed from that terminal. Unsuccessful verification at either removal stage or reconnection stage may result in the memory being erased, thereby protecting contents from unauthorised access.

Title: Mold opening and closing mechanism using a controllable electronic motor
Inventor: GRANT MARTY J
IPC: C03B9/16
Filed: 1998-11-04
Abstract: A mold opening and closing mechanism for an I.S. machine has a plurality of individual sections, each having a pair of opposed mold support mechanisms (16) displaceable between a separated retracted position and an advanced position where molds carried by the mold support mechanisms will forcefully engage. A drive (19) is operatively associated with each mold support mechanism, and includes an electronic motor. A predetermined torque is applied to the motors for a period of time when the opposed pair of mold support mechanisms are at the advanced position. To return the mold support mechanisms to the start position the electronic motors are operated at a slow velocity for a period of time and then operated to rapidly displace the mold support mechanisms to the start position.
Patent GB-2338117-A (GB)
Title: Variable axial airgap rotary electric machines
Inventor: PULLEN KEITH ROBERT
IPC: H02K3/26
Filed: 1998-12-01
Abstract: A rotary electrical machine comprising a stator 10 and at least one rotor 12 having a plurality of permanent magnets 14. The rotor consists of a rotor disc, at the outer edge of which the permanent magnets are mounted. The rotor disc 12 is provided with airgap varying means 19 which are angled towards the stator 10 and mounted on the rotor hub 24 for rotation therewith. When the rotor is stationary, the airgap 30 between the magnets 14 and the stator 10 is at a minimum. In operation, as the speed of rotation of the rotor 12 increases, a centrifugal force is generated which acts to bend the airgap varying means 19 and, therefore, the rotor disc 12 back, away from the stator 10, thereby drawing the magnets 14 away from the stator and increasing the size of the airgap 30. The increase in size of the airgap results in a corresponding decrease in flux and therefore a decrease in the maximum output voltage for that rotor speed. In this way, the output voltage of the machine is kept substantially constant. A stationary iron ring 32 may be provided on the stator 10 to assist in drawing away flux as the size of the airgap is increased. Stator-windings are disclosed.

Title: Encoding a contour of an object in a video image by octant-based vertex coding
Inventor: CHO SUNG-RYUL
IPC: H04N7/26
Filed: 1998-12-18
Abstract: In a method for encoding a contour of an object in a video signal based on a vertex information representing a position and an index of an octant corresponding to each vertex of the contour, a maximum length line segment (MLLS) is first detected, at step 401, among line segments for the contour based on the vertex information (VI). Then, an initial vertex position information (IVPI) and a final vertex position information (FVPI) for the contour are encoded, at step 402, the initial vertex and the final vertex being two vertices constituting the MLLS. Thereafter, a first bit number (FBN) and a second bit number (SBN) for the contour are set 403, wherein the FBN is the number of bits required to encode the MLLS and the SBN is the number of bits calculated by using the FBN, typically being FBN-1. In a subsequent step 404, each of the vertices are classified based on the SBN and the VI either as a first vertex (FV) or as a second vertex (SV) to thereby provide first vertices (FV's) and second vertices (SV's) Then, an escape signal (ECS) for each SV is produced at step 405 to supply a plurality of ECS's for the SV's. The numbers of the FV's (NFV) and the SV's (NSV) for the contour are calculated, at step 406, respectively. Thereafter, each of the FV's and the SV's is encoded with either the FBN or the SBN based on the ECS's and the comparison result for the NFV and the NSV to thereby provide encoded FV's and encoded SV's.

IPC: C02F1/00
Filed: 1999-09-22
Abstract: Liquid levels within an industrial manufacturing or refining plant, or within apparatus for separating liquids of different specific gravities eg oil and water, are controlled by an adjustable height weir. The weir is constituted by the rim 16 of a dish 15, which is adjustably mounted on a central pipe 13 by means of rack and pinion, screw threads or friction. The height of the rim governs the rate of flow of liquid out of or into the pipe, or the surface level of a body of liquid which is connected to liquid within or outside the pipe. The weir may be used alone (Figs 1A, 1B) or, as shown, it may be augmented by a second weir 25 of larger capacity, with a slightly higher rim 26. This accommodates upstream surges without flooding. There may be more than two weirs in the series. The rim of the weir may be formed with projections 36a, 36b.
