Title: Preventing a vehicle battery from being excessively discharged
Inventor: JEONG BYUNG CHUN
IPC: B60R16/03
Filed: 1997-09-10
Abstract: In a vehicle having an engine, a battery (1, Fig.1A), and a generator driven by the engine for charging the battery, a switching unit 2 is controlled to disconnect the battery from electrical load devices at the end of a predetermined time delay following stopping of the engine. The switching circuit 2 disconnects the load devices immediately the engine stops if a battery voltage monitoring circuit (7) detects that the battery voltage is below a certain level. An engine monitoring unit (3) responsive to ignition pulses causes a monostable (4A) to output a high signal as long as the engine is running, so that a transistor Q2 is then on and a load control relay switch RY2 is closed. When the engine stops, a counter arrangement (5B, 5C) causes transistor Q2 and thus relay RY2 to turn off after the predetermined delay. A manually operated override switch 8 may be operated to keep the relay RY2 on continuously after the engine has stopped. A warning buzzer 11 and LED4 are operated for a predetermined time after the engine has stopped, if either the switch 8 has been operated, or the monitoring circuit (7) detects low battery voltage, or a monitoring circuit 9 senses a discharge current from the battery (eg. due to a light being inadvertently left on).

Title: Image colour conversion
Inventor: GONDEK JAY S
IPC: G06T1/00
Filed: 1997-10-15
Abstract: The method transforms image points in an input colour space to image points in an output colour space using a first set of control points (P0 - P7) arranged at the corners of cubes in the input colour space and a second set of control points (P8) in input colour space which are within the cubes, each control point having a corresponding value in output colour space, and interpolating between the output values according to the control points. Preferably the first set of control points comprises a cube lattice of 9x9x9 points and the second set comprises a further 512 points at the centre of respective cubes. The second set provides a separate 8x8x8 lattice of control points and they are stored in a separate table. The second set of points significantly improves the accuracy of colour conversion without unduly increasing the memory required for storing control points.

Title: Auxiliary washing device for a washing machine
Inventor: RA JUN-HO
IPC: D06F15/00
Filed: 1997-11-28
Abstract: An auxiliary washing device in a washing machine comprises a beam (260) mountable on an upper side of an outer tub (110) and extendable into a inner space of a washing tub (120), where a washing bar (600), capable of swinging, is supported at an extended end of the beam. The washing bar is swung upwardly by a motor (320) and downwardly by a torsion spring (560). When electric power to the motor is stopped at the position in which the washing bar is swung upwardly by the motor, the washing bar swings downwardly by the torsion of the torsion bar to strike laundry in the washing tub. This impact enhances the washing of the laundry, as the laundry is stirred upwardly and downwardly, and so improves washing efficiency in the upper part of the washing tub.

Title: Method of testing noise and ditortion created within a computer audio system
Inventor: CHANG VAM
IPC: H03M1/10
Filed: 1999-01-14
Abstract: A method of testing the noise and distortion created within a computer audio system comprises using the FM synthesiser, of the audio system, to provide a sinusoidal signal to the input of the audio system's analog to digital converter. The analog input signal is converted to a digital signal which is stored. The stored digital signal is used by the computer to calculate the signal to noise ratio and the distortion of the audio system. The signal to noise ratio and distortion values are then compared to respective predetermined standards to judge whether they are satisfactory. The analog to digital converter may use pulse code modulation. The computer may differentiate between the predetermined input signal waveform and the resulting stored digital signal to derive the distortion level whilst the signal to noise ratio is obtained by comparing the total power of a predetermined waveform signal to that of a zero level input signal. The total power is obtained by integration of the respective stored digital signals.
