    摘要: Eddy currents arise when a conductive material moves through a magnetic field. Eddy currents, like all electric currents, generate a magnetic field. The generated magnetic field can be detected and measured through use of one or more magnetically biased GMR elements. In general, an eddy current sensor can be configured, which includes a magnet, and a first giant magnetoresistive element placed such that the magnetic field from the magnet biases the giant magnetoresistive element along its primary axis.

    摘要: An integrated circuit magnetoresistive speed and direction sensor generally utilizes an AMR bridge circuit thereby allowing for increased air gap performance as compared to conventional Hall-effect element based sensors. The AMR sensor is capable of sensing ring magnets or bar magnets magnetized with one or more magnet poles along the desired travel. The number of poles of the magnet should be optimized based upon the application design. In order to obtain speed and direction information, two bridge circuits can be placed within proximity (I.e., the exact location and shape of the bridge can be determined based upon the target and desired performance) of each other. The signals of the two bridge circuits can be compared on integrated electronics. The bridges are generally rotated 45 degrees to reduce and/or eliminate offsets, which provide the sensor with a large air gap performance.

    摘要: Apparatus for stripping ceramic coatings from the surfaces of articles. The apparatus includes a dedicated pressure vessel, such as an autoclave, which is maintained at an elevated temperature. Caustic solution is preheated to a first elevated temperature before injecting it into the autoclave, and the caustic solution is filtered and cooled after use in the autoclave. The articles are stripped of coating by maintaining the articles at an elevated temperature and pressure for a predetermined time. Various options include the use of analytical equipment to maintain the chemistry of the caustic solution and use of a volatile organic solution to prepressurize the autoclave and shorten cycle time. The autoclave is maintained in a nitrogen chamber to minimize the risks associated with volatile components. The articles are transferred to a separate pressure vessel after completion of the stripping operation so that the autoclave used for stripping can be maintained at an elevated temperature, thereby shortening the cycle time for stripping of additional articles.

    摘要: In one aspect, the present disclosure is directed to a method for controlling operation of an electric water pump configured to circulate a cooling fluid. The method may include detecting a startup of an electric power source associated with the electric water pump. In addition, the method may include monitoring a voltage available to the electric water pump in response to the detected startup of the power source. The method may also include providing an activation signal to the electric water pump if the monitored voltage is equal to or greater than a first threshold voltage.

    摘要: Latch control methods and systems are disclosed, including a latch that receives power from a motor associated with an H-bridge circuit. A sensor can be provided for monitoring the latch, wherein the sensor obtains latch feedback data from the latch. A microcontroller controls the latch based on the latch feedback data, by controlling an interaction of the H-bridge circuit and the motor with the latch. Additionally, a microprocessor processes instructions for controlling the interaction of the H-bridge circuit and the motor with the latch. Such instructions can be implemented as Proportional Integral Derivative (PID) control instructions.
