Title: Hidden surface elimination and Gouraud shading
Inventor: KOHN LESLIE DEAN
IPC: G06T15/40
Filed: 1989-12-13
Abstract: A Z-buffer check instruction performs multiple, simultaneous unsigned-integer (ordinal) comparisons of newly computed distance (Z) values with the contents of a Z-buffer. Distances of points to be drawn are compared with corresponding values in the Z-buffer, and appropriate bits of a one-bit pixel mask are then set to designate those pixels for which the points to be drawn are closer (smaller) than the Z-buffer values. Previously calculated bits of the pixel mask are shifted so that consecutive Z-buffer check instructions accumulate their results in the pixel mask register. A pixel store instruction utilizes the pixel mask to update only those pixel locations in a frame buffer which correspond to a point on a newly rendered surface closer than the surface represented by the current pixel value. …<??>Further instructions operating in a similar manner provide for linear interpolation of distance values stored in the Z-buffer and the linear interpolation of pixel colour intensities (Gouraud shading).

IPC: B60C23/00
Filed: 1989-12-30
Abstract: A tyre safety device ensures that substantially equal pressure is present between the tyros of a double-tyre wheel and also warns when any one of the tyres become seriously underinflated or when an excessive temperature condition exists in the tyres. The device comprises a control block 1 adapted to be fitted on a double-tyre wheel, the block 1 including a through-conduit 6A -6C which is connected to the valves of the two tyros of the wheel to provide equal pressure conditions between the tyres. A pressure sensitive valve 11 - 14 closes the through-conduit 6A - 6C when there is an excessive air pressure fall. The valve 11 also operates an actuator 18 of a switch 24A, 25A, 26A in an electric warning circuit for the generation of a warning signal. The actuator 18 is pan of a telescopic arrangement enabling the switch contacts 24A, 25A, 26A to be housed internally for contamination protection. Additionally, a temperature responsive device 31 surrounding the actuator 18 reacts with a frusta-conical wall 18B of the actuator to move the actuator for closure of the warning circuit switch at an excessive air temperature condition in the through conduit. <IMAGE>

Patent GB-2246916-A (GB)
Title: Battery charger
Inventor: ZHU YUAN JING
IPC: G01R31/36
Filed: 1990-08-10
Abstract: The charger has a timer 30 coupled to a display 32 to give an indication of the amount of charge added to the battery 24. The display may be calibrated to show the actual charge in mAH or may indicate the time for which the battery can be used in, eg., a mobile telephone. Operation of a switch P1 energises a relay coil C1 causing the battery 24 to be first discharged through a resistor R1 until the relay C1 drops out whereupon a relay coil C2 is energised resulting in pulse charging of the battery 24 via a transistor T1 and operation of the timer 30. A switch 22 can adjust the pulse width to change the charging rate and is ganged to a switch 34 which changes the dividing ratio of a divider in the timer 30. Coil C2 is deenergised to stop charging when circus C1, COM 1, COM 2 detects that the battery voltage has started to decrease after reaching a peak. The battery may be charged without the initial discharge stage if switch P2 is operated instead of switch; the display 32 will then indicate the charge added rather than the actual charge state of the battery. <IMAGE>

Abstract: Increasing the effective coherence length of non-stabilized lasers in interferometric devices enabling them to be used in displacement-measuring interferometers with large optical path differences. Laser beam (201) is split into a measuring (204) and reference (203) beam. The interference pattern of each mode of the laser is separated by means (208), and electro-optical counting detectors (211, 212) produce fringe counts for each mode. Mode selector means (213) determines which mode signal provides the optimum output at any instant, and this mode signal is used by the main counter after compensation for wavelength difference between the two modes. <IMAGE>
Patent GB-2257531-A (GB)
Title: Measuring dwell angle
Inventor: CLEMENTS STANLEY RICHARD
IPC: F02B1/04
Filed: 1991-06-19
Abstract: A dwell-angle measurement technique involves use of a circular calibrated dial releasably attached to the distributor shaft, a pointer or reference circle and an electrical detector, e.g. a lamp in the primary ignition circuit. The dial is caused to turn to an angular position where the contact breaker points close and the lamp turns on. The dial is then unlocked from the distributor shaft and its zero reference mark is aligned with the reference pointer or centrally positioned in the reference circle, and is then relocked to the distributor shaft. The distributor shaft is now caused to turn to a position where the electrical detector indicates the contact breaker points have opened.   The angle through which the dial has turned indicates the dwell angle. The dial may be in the form of a circular protractor; and a reference pointer or reference circle formed on a liquid-filled circular tube may co-operate therewith. <IMAGE>

Title: Testing optical fiber using optical heterodyne technique
Inventor: TAKEDA TOSHIYUKI
IPC: G01M11/00
Filed: 1991-09-26
Abstract: In apparatus for testing an optical fiber by using a pulsed light beam, a coherent light beam emitted from a light source (1A) is branched into a signal light beam and a reference light beam. The signal light beam is shifted in frequency by a predetermined amount and pulsed (at 1C), to be subsequently input to an optical fiber (10) under test through a directional optical coupler (1E), which then receives return light beam from the fiber which is mixed with the reference light beam. A polarized light beam splitter (2) separates the light beams from the directional optical coupler into first and second orthogonally polarized light components, which are then converted into first and second electric signals, hetorodyning occurring at the detectors (4A, 4B). A phase corrector (5) matches the first electric signal in phase with the second signal. An adder (6) adds together the output of the phase corrector with the second electric signal. Effects of polarisation are reduced thereby. <IMAGE>

Title: Moulded shells and methods of forming
Inventor: MACDOUGALL GARY DOUGLAS
IPC: B29C65/02
Filed: 1992-02-13
Abstract: Rotational moulding powder is poured into a mould such as the outer shell mould 12 for a boat. The inner and outer shell moulds 11, 12 are then aligned to give a distance "d" between the bottom of the rim 18 and the surface 22, and a distance "d+t" between the faces 19, 20 and 21 and the lower faces 14, 15 and 16, where "V" is the required final thickness of plastic in those regions. The combined mould is then rotated and heated so that the moulding powder flows over the entire internal surface. The inner and outer moulds 11, 12 are then brought together by the distance "d", and since the mould plastic is still in a soft state, plastic formed between the lower faces 14, 15 and 16 and the faces 19, 20 and 21 is squeezed together, thereby forming a homogeneous connection. The stiffening members 13 are thus formed integrally with the moulded shell. <IMAGE>
