Title: Testing and speed control of ABS pump motors
Inventor: BOLTON JOHN ANTHONY
IPC: B60T8/174
Filed: 1993-12-10
Abstract: A vehicle anti-lock braking (ABS) system has a motor-driven pump (10) providing a hydraulic supply to the ABS system. The pump motor speed is controlled by an electronic switch (16), such as a MOSFET, Pulse Width Modulated in accordance with a measurement of the e.m.f. generated by the motor between pulses and after a delay to allow the back e.m.f., caused by switching off the motor, to decay (preferably to zero) before the measurement operation begins. The generated voltage is integrated during a motor switch-off period, the motor speed being determined from a knowledge of the voltage/speed characteristic of the particular motor, when acting as a generator. The ignition switch-controlled supply within the vehicle electrical system only operates a logic gate (40) to control the supply of direct battery power to the vehicle voltage regulator (36), the pump motor circuit and its electronic controller (16) being connected directly to the battery supply (B+) whereby to act as an energy sink to protect all silicon devices in the electrical control system except the ignition circuit logic gate means. The motor circuit can be tested by monitoring the effect of a short pulse from the logic, which is not sufficiently long to move the motor. <IMAGE>

Title: An irrigation system
Inventor: CRAWSHAW KENNETH
IPC: G05D22/02
Filed: 1994-01-20
Abstract: An irrigation system for automatically watering soil, eg. in a greenhouse, including a resistive-type soil moisture sensor 18, 19 for producing a first electrical signal representative of actual soil moisture content, a comparator 22 for comparing the first electrical signal with one or more further electrical signals representative of required moisture contents, and for producing an output signal in the event of a deviation from a required moisture content, and a pump 14 adapted to supply water to the soil and actuated in the presence of the output signal. The duration of water flow is determined, in one embodiment, by the output signal from the comparator 22 or in another embodiment, by a timer 55. Hysteresis between switching on and off the water supply can be provided. In one embodiment the measurement of moisture is disabled whilst the pump is actuated and a display indicates which of sampling and pumping is currently being effected. A manual override and means to determine when the sensors are incorrectly located in the soil can also be provided. <IMAGE>
