Title: Position sensor
Inventor: SEARLE DAVID GEOFFREY
IPC: G01D5/20
Filed: 1989-02-22
Abstract: A homopolar magnetic field, which is asymmetric with respect to the axis of a rotor 6, is produced by a stator-mounted exciting coil 5 of a sensor for indicating the position of the rotor 6 in an electric motor. A further coil eg single loop 7 on the rotor 6 modifies the field of the exciting coil 5. This modification varies in dependence on the angular position of the rotor 6. A resulting output signal is produced in a sensing coil 10 carried by the stator. A second sensing coil 10' displaced 90 DEG  from the first may be provided. <IMAGE>

Title: Lighting circuit for vehicular discharge lamp
Inventor: YAGI SOICHI
IPC: B60Q1/04
Filed: 1991-03-25
Abstract: A metal halide lamp 16 is energised from the vehicle battery 2 via a high frequency inverter 10 supplied by a DC voltage booster 9 which normally operates to provide constant power to the lamp 16. However. if the battery voltage drops below 9.5V, the booster 9 is controlled to provide less than the normal constant power level, whereby increased heat generation due to increase in current consumption is avoided. A linear reduction in power from 100 per cent to 40 per cent of normal power is effected as battery voltage falls from 9.5V to 7V, (Fig 6), at which level the circuit cannot further maintain lighting of the lamp. A low voltage reset circuit 24a senses battery voltage below 7V and causes a relay 6 to open a contact 6a thus de-energising booster 9. Contact 6a is also opened if a detector 24 senses an abnormality, such as failure of the lamp 16 to light. A timer circuit 22 prevents booster 9 from operating in the constant power mode during lamp starting, the output voltage of booster 9 then being 2.5 to 3 times the normal value. <IMAGE>
