Title: Apparatus for processing auxiliary information in an extended definition widescreen television system
Inventor: ISNARDI MICHAEL ANTHONY
IPC: H04N11/24
Filed: 1990-02-12
Abstract: An NTSC compatible, single broadcast channel, widescreen EDTV system encodes and decodes a television signal comprising four components: (1) a main, standard format NTSC signal (N) with low frequency side panel image information compressed into the overscan regions thereof; (2) time expanded high frequency side panel image information (X); (3) extended high frequency horizontal luminance image information (Z); and (4) vertical-temporal luminance image information (YTN). Components (2) (X) and (3) (Z) are intraframe averaged (64, 76) and quadrature modulate (80) an alternate subcarrier (ASC), e.g., at 3.108 MHz, to produce a modulated signal (M). The modulated signal is summed (40) with component (1) after intraframe averaging to produce an NTSC compatible 4.2 MHz baseband signal (NTSCF). This signal and component (4) quadrature modulate (57) an RF picture carrier to produce an NTSC compatible RF broadcast signal for transmission via a single broadcast channel.

Title: Flushing cistern for a W.C.
Inventor: YEO STEVE SIOW KUANG
IPC: E03D1/34
Filed: 1990-07-25
Abstract: A flushing cistern for a toilet having an outlet chamber (3) swept by a piston. The piston carries a closure element (25) of an outlet valve (8) of the chamber, and is biased into the valve closing position by a spring (16). The piston comprises a non-return valve (6), which comprises two separable plates (18, 24). Operation of a flush lever (5) causes the piston to be retracted from the outlet valve, which separates the plates, allowing water flow through apertures in the plates. Retraction of the piston compresses the spring such that on release of the flush lever the spring causes the piston to return to its original position. The return stroke of the piston closes the plates, thus pressurising the outflow of water downstream of the piston. <IMAGE>

Title: Self-retracting door restraint
Inventor: PRUDEN ROGER PHILIP
IPC: E05B45/06
Filed: 1992-10-08
Abstract: A self-retracting door restraint comprising a retracting assembly (1), a belt (2), belt-catch (3), and a receiving bracket (4). To use the door restraint the belt-catch is engaged with the receiving bracket. Now, as the door opens the belt unwinds. When it is fully unwound the door is restrained from opening any further. Similarly, as the door closes the belt rewinds. Disengaging the belt-catch from the receiving bracket leaves the belt free to rewind and the door free to open. An electronic circuit sounds an alarm if the belt remains fully unwound for more than a preset time. An alarm is also sounded if the belt completely rewinds into the retracting assembly, without being prevented from doing so by the belt-catch, such as would happen were the belt to be cut or broken. <IMAGE>

Title: Flow meters
Inventor: WORKMAN CERI WILLIAM
IPC: G01F23/26
Filed: 1994-01-26
Abstract: A flow meter comprises a measuring vessel 2 having an inlet 10 and an outlet 16. The level of fluid in the vessel 2 is measured by a capacitive level sensor comprising a central electrode 18 and the outer wall 12 of the vessel 2. The outlet 16 of the vessel 2 is provided with a controlled discharge valve 24, the discharge characteristics of which are known. During a filling operation of the vessel 2, when the discharge valve (24) is closed, the flow rate into the vessel is determined from the rate of change of the output of the capacitive level sensor. During a discharge operation, when the discharge valve 24 is opened, the flow rate into the vessel 2 is determined from the discharge characteristics of the valve 24 and a knowledge of the pressure in the inlet passage which, may be obtained from a measurement of temperature in the inlet passage. The height to which the vessel 2 is filled before opening valve 24 may be varied. The meter may be used for condensate discharged from a steam system. <IMAGE>

Title: Fingerprint identification system
Inventor: MATSUMURA YOSHIHIDE
IPC: G06K9/00
Filed: 1994-04-21
Abstract: A fingerprint ID system, which compares input fingerprint image data with registered data, scans input fingerprint image data, thins it and extracts minutiae. Pseudo minutiae representing breaks or noise are removed and the minutiae are registered based on positions of branch points and their positional relationships. The mismatch between branch points in the fingerprint image data and the registered data is scored and the examinee is judged to be the person of the registered data when the score is under a predetermined value. When the recognition rate based on minutiae of a fingerprint is low, template matching data is registered and template matching of the input fingerprint image data against the registered data takes place.   <IMAGE>
