Abstract: This invention provides a combination treatment and compositions for alleviating the symptoms of a cardiovascular disorder in a mammalian patient, which comprises administration to the patient of an effective amount of synthetic and/or semi-synthetic bodies carrying phospholipid ligands on their surfaces, said bodies have a size of from about 20 nanometers to about 500 microns; and an effective amount of a cardiovascular drug.

Abstract: Mammalian disorders associated with a deficiency in the cytokine interleukin-10 (IL-10) can be alleviated by stimulating in vivo secretion and/or activity of IL-10 in the patient's blood or tissues by application of external stimulus.

Abstract: A vehicle anti-lock braking (ABS) system having a motor-driven pump (10) for providing a hydraulic supply to the ABS system. The pump motor (10) is controlled by a series device in the form of an electronic switch (16), such as a MOSFET, to enable frequent testing of the motor circuit by short pulses which produce no significant noise. Feedback to control motor speed is obtained by measuring the e.m.f. generated by the motor (16) after it has been switched off 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 established in this period by subtracting the measured integrated voltage when acting as a generator from the main supply voltage (B+) .

Abstract: In a control system, for instance forming part of a vehicle anti-lock brake system, a plurality of control processors provides similar or identical control signals of the system in response to a shared transducer input. An independent data correlation processor compares data generated in the control processors for correlation and, in the absence of proper correlation, provides an indication which may be used to disable anti-lock operation of the brake system. In preferred embodiments, a four wheel vehicle with an anti-lock brake system is monitored by dual microprocessors. Each wheel has a speed sensor which supplies an input to each microprocessor. The data correlation processor compares the outputs of the microprocessors for each wheel and sends and alarm or disables the anti-lock brake system if the difference in the microprocessors output is beyond a limit amount.
