Abstract: A machine having an operator interface for requesting an action from an actuator of the machine includes a movable component of the operator interface. The movable component is movable among at least two positions. One of a magnet and a Hall effect sensor is positioned to move in response to movement of the movable component. The other of the magnet and the Hall effect sensor has a stationary position relative to the movable component. A pulse width modulator is operably coupled to the Hall effect sensor for producing a first pulse width modulated signal. The first pulse width modulated signal is altered in response to movement of one of the Hall effect sensor and the magnet relative to the other. An electronic controller is in communication with the pulse width modulator and the actuator and is configured to actuate the actuator in response to evaluation of the first pulse width modulated signal.

Abstract: A thermal barrier coating and deposition process for a component intended for use in a hostile thermal environment, such as the turbine, combustor and augmentor components of a gas turbine engine. The TBC has a first coating portion on at least a first surface portion of the component. The first coating portion is formed of a ceramic material to have at least an inner region, at least an outer region overlying the inner region, and a columnar microstructure whereby the inner and outer regions comprise columns of the ceramic material. The columns of the inner region are more closely spaced than the columns of the outer region so that the inner region of the first coating portion is denser than the outer region of the first coating portion, wherein the higher density of the inner region promotes the impact resistance of the first coating portion.

Abstract: An article comprising a substrate and a plurality of coating units disposed over the substrate is provided. Each coating unit comprises an oxygen-getter layer and a barrier layer. Embodiments of the present invention introduce redundancy to enhance the robustness of a coating system. Multiple protective coating units are disposed over a substrate so that failure of one of the coating units will be far less likely to subject the substrate to direct risk of exposure to the environment. Failure of an outer coating unit merely exposes a pristine protective coating unit, rather than the substrate or a less protective coating layer. In this way, embodiments of the present invention drastically reduce reliance on the performance of one particular coating layer, promoting a more robust and reliable system.

Abstract: Method 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 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.

Abstract: 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.

Abstract: Latch control methods and systems are disclosed, including a latch that receives power from a motor associated with a latch. A sensor can be provided for monitoring the current consumption of the motor. A microcontroller can control the latch and/or the motor, based on the current consumption data received from the sensor concerning the current consumption of the motor. Monitoring of the current waveform of the motor therefore provides speed and direction feedback data for control of the latch. Additionally, a microprocessor can process instructions for controlling the interaction of the motor, the latch, the sensor and/or the microcontroller. Such a current monitoring control system is made possible by variation in current consumption of the motor during rotation as a result of commutation, which can be interrogated by measuring the voltage drop across the motor or a shunt resistor, or through the use of other current sensors, such as, for example, a Hall-effect type current sensor.

Abstract: 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.

Abstract: 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.

Abstract: A keyless entry method, system and program product is disclosed herein. In general, user command information can be transmitted to a receiving and transmitting unit which communicates with a latch. A processor can then process the user command information utilizing a processor, which communicates the latch and the receiving and transmitting unit. The latch can thereafter be instructed to perform a particular latch function (e.g., opening or closing a vehicle door), in response to processing the user command information utilizing the processor.
