摘要： A relative velocity sensor in a vehicle suspension damper comprises an annular, radially polarized magnet at the top of the shock cylinder adjacent a sensor winding on the inside of the dust tube. A closed magnetic circuit is defined from the magnet through an annular magnetic member inside the magnet to the piston rod and back through the dust tube across the sensor winding to the magnet. Flux below the magnet is similarly confined through the cylinder and does not affect the sensor winding. The air gaps at the winding and the piston rod do not change with axial movement; and the flux linkage variation with axial movement is thus linear across the entire coil. A voltage is generated across the coil which is a strong and accurate signal of relative movement between the sprung and unsprung masses of the vehicle.

摘要： A closed loop control circuit for regulating the response of an automatic temperature control system is disclosed. The temperature control system provides automatic regulation of the temperature for the passenger compartment of a vehicle by positioning a blend air door in response to three control parameters. Two of the control parameters, the actual temperature of the passenger compartment and the desired temperature of the passenger compartment, are serially combined in one leg of a bridge circuit and compared against another leg of the bridge presenting the third control parameter, the position of the blend door. An unbalanced condition in the bridge circuit is corrected by the repositioning of the blend door until the error between the two legs is nulled. Repositioning is accomplished by a pair of differential amplifiers which detect the sense of the error and thereafter provide an interrupter control function to a vacuum modulator. The interrupter control function is accomplished by current limiting open collector output devices in the amplifiers. The interrupter function regulates the vacuum level in the modulator which positions the blend air door through a vacuum actuator.
摘要翻译：公开了一种用于调节自动温度控制系统的响应的闭环控制电路。温度控制系统通过根据三个控制参数定位混合气门来提供车辆乘客舱室的温度的自动调节。控制参数中的两个控制参数，乘客舱的实际温度和乘客舱的期望温度被串联地组合在桥接电路的一条腿中，并与桥梁的另一条腿相比较，呈现第三控制参数，混合门桥梁电路中的不平衡状态通过混合门的重新定位来校正，直到两个腿之间的误差为零。重新定位由一对差分放大器来实现，该差分放大器检测误差的感觉，然后向真空调制器提供中断器控制功能。断路器控制功能由放大器中的限流开路集电极输出器件实现。中断器功能调节调制器中的真空度，使调和气门通过真空执行器。
