    摘要: An apparatus for on-line optical monitoring of the quality and/or chemical condition of a fluid; in particular, a hydrocarbon-based fluid used in transportation and industrial applications. The apparatus includes an IR-transparent internal-reflectance-element (IRE) that has at least one essentially flat surface and at least one convex surface, and at least two IR light paths of uniquely determined central-frequency and bandwidth with light from a source entering a flat surface of the IRE, internally reflecting at least once from at least one convex surface of the IRE that can contact a fluid, exiting a flat surface of the IRE, and being received at a detector. The apparatus also includes electronics to power the source and receive output from the detector of each light path. The apparatus can be controlled to independently monitor the IR light reflected within the IRE at the uniquely determined frequency of each path, and to communicate information relevant to the IR light detected.

    摘要: An apparatus for driving a motor comprises a drive signal generation circuit configured to produce pulses on a pulse-width modulated drive signal in response to a control signal. A detection circuit is coupled to receive a commutation signal from the motor to monitor the speed of the motor. A control signal generation circuit is configured to dynamically generate the control signal so that a frequency of pulse-width modulated drive signal corresponds with the duration of the phase of the motor, so as to reduce the occurrence of an incomplete pulse on the drive signal. Methods for driving a motor are also disclosed.

    摘要: Magnetic field sensors have a magnetic field sensing element and also a feedback circuit to provide a gain-adjustment signal to affect a sensitivity associated with the magnetic field sensing element. In some arrangements, the feedback circuit can include piezoresistors to sense a strain of a substrate over which the magnetic field sensor is disposed. With these arrangements, the feedback circuit can generate the gain-adjustment signal in accordance with the sensed strain. In other arrangements, the feedback circuit can generate pulsed magnetic fields proximate to the magnetic field sensing element in order to directly measure the sensitivity of the magnetic field sensing element. With these arrangements, the feedback circuit can generate the gain-adjustment signal in accordance with the sensed sensitivity.
