摘要： An integrated lead flexure includes a base region and a gimbal extending from the base region and having a slider mounting region. A conductive assembly, which is configured to carry current between the slider mounting region and the base region, includes a current carrying structure electrically connected with a pattern of conductive lossy material. The pattern of conductive lossy material is configured to reduce a bandwidth of the current carrying structure.

摘要： A magnetic flowmeter system provides a volumetric flow rate output and has a coil receiving a magnetic field producing coil current from the current supply circuitry. The current supply circuitry includes an H-bridge transistor circuit having first and second switches which couple one of the first and second coil wires to a supply conductor. Third and fourth switches of the bridge circuit couple the other of the first and second coil wires to a second supply conductor. A control circuit periodically alternates conduction of the first, second, third and fourth switches to reverse the polarity of the coil current. A coil current control circuit generates a non-alternating output representing the sensed alternating coil current amplitude. The control circuit modulates the conduction duty cycle of the third and fourth switches as a function of the non-alternating output to regulate the coil current amplitude to a selected level.
