Title: Inhibiting starting of a motor vehicle engine by an intoxicated driver
Inventor: CRABTREE BRIAN KENNETH
IPC: B60K28/06
Filed: 1987-02-04
Abstract: A motor vehicle's ignition circuit 10 comprises a battery 12, a primary switch 14, a key operated switch 16, and an ignition system 18 including a starter motor. The operation of the primary switch 14 is controlled by a breath analyser 20 whereby a sample of breath is passed via an inlet nozzle 22 into a fuel cell 24 generating a voltage the value of which is proportional to the alcohol content of the breath sample. Comparison means 26 compare this value to a pre-determined value. If the generated value is higher than the pre-determined value the primary switch 14 remains off preventing the ignition system 18 from being energised thus inhibiting starting of the motor vehicle. If the generated value is lower, the primary switch 14 is closed and the vehicle's engine may be started. The breath analyser 20 may include a heater to ensure operation at a substantially constant temperature. The analyser 20 and switch 14 may be encapsulated in resin to prevent tampering. A test based on a change of colour of a solution of potassium dichromate and sulphuric acid may alternatively be used. <IMAGE>

Title: Aircraft braking system
Inventor: STIMSON IAN LEONARD
IPC: B60T8/00
Filed: 1989-02-14
Abstract: An aircraft braking system for a main undercarriage or undercarriages incorporates at least two brakes, which may be carbon type brakes, and a control unit for selectively disabling at least one brake during taxiing only, the control unit being arranged to ensure that the disabling of the brake or brakes does not affect the directional stability of the aircraft when the braking system is operated.
