摘要： A system for sensing a fluid. The system including a fixed object; a first transducer generating a first sound wave in a horizontal direction and to detect a first echo of the first sound wave from the fixed object; a second transducer generating a second sound wave in a vertical direction; a temperature sensor detecting a temperature of the fluid; and a controller. The controller configured to produce a first signal to drive the first transducer to produce the first sound wave, produce a second signal to drive the second transducer to produce the second sound wave, receive a first indication of the detected first echo, receive a second indication of the detected second echo, receive a temperature indication, determine a quality of the fluid based on the first indication and the temperature indication, and determine a quantity of the fluid based on the second indication.

摘要： A system and method for performing a diagnostic assessment of an ultrasonic sensor that measures a fluid level. A PWM signal is generated based on a reflection of an ultrasonic signal output by the ultrasonic sensor. The PWM has a period, and a plurality of pulses. Each pulse encodes a predetermined parameter and has a width. The PWM signal encodes the fluid level, fluid temperature, fluid speed of sound, and a status of the ultrasonic transducer. The PWM signal is received at a processor. The processor performs the diagnostic assessment of the ultrasonic sensor based on the period of the PWM signal and the widths of the plurality of pulses of the PWM signal. The processor is able to detect time reference shifts by assessing the PWM signal.

摘要： A sensor having a first array of N magnetic pole pairs, where N is a positive number, and a second array of M magnetic pole pairs, arranged substantially in parallel to the first array, where M is a positive number different from N, such as N−1 or N+1. A first magnetic pole in the second array is aligned with a first magnetic pole in the first array. The remaining magnetic poles in the second array are arranged such that each one of them is positioned with respect to at least one pole in the first array to form a magnetic field with an angular orientation with respect to the two poles. This arrangement of magnetic pole pairs can be used to measure absolute position. A third array of M magnetic pole pairs may be arranged substantially in parallel with the second array. The second and third arrays of magnetic pole pairs may be used to measure relative position between the two arrays.

摘要： A method of securing a pressure sensor diaphragm to a pressure sensor base, including the steps of positioning the pressure sensor diaphragm over the pressure sensor base, placing a pressure sensor cap over the pressure sensor diaphragm, applying a tensile force to at least a portion of the cap, and deforming a portion of the cap around a portion of the base. The applying step can occur before the deforming step by engaging a portion of the cap and advancing the base toward the cap to create tension in a portion of the cap. This creates a tensile preload in the cap. The applying step can instead be performed during the deforming step by engaging a first portion of the cap and advancing a second portion of the cap toward the first portion of the cap and around a portion of the base. This can create tension in a portion of the cap when the deformation operation is being performed.

摘要： A sensor for detecting the angular velocity of a rotating member. The sensor includes a bobbin having an exterior defining an annular recess and a coil within the recess. The bobbin also has a generally cylindrical aperture and supports a probe and a permanent magnet in the aperture. The housing is secured to the bobbin and the housing and bobbin include tapered inner and outer surfaces, respectively, that are made to form a wedge fit seal between the bobbin and the housing to prevent the introduction of molding material during the overmolding process. The bobbin also includes supports for supporting the lead wires extending between the coil and the terminals.

摘要： A bearing assembly for a vehicle including a fixed element, a rotating element rotating relative to the fixed element about an axis, and an annular sensor connected to one of the fixed element and the rotating element. The sensor includes a pick-up coil and an annular magnet connected to the pick-up coil. The magnet has a plurality of magnetic regions which alternate in polarity around the magnet. The magnet generates a magnetic flux path magnetically coupling the magnet to the coil and resulting in the generation of an electrical signal in the coil. The rotating bearing element includes a plurality of gear teeth. The gear teeth generate a change in the reluctance of the magnetic flux path to vary the electrical signal in response to the angular speed of the fixed element relative to the rotating element.
