Abstract: Systems and methods described herein provide for testing and debugging different subsystems of an embedded controller using a testing architecture. The testing architecture can simulate messaging interfaces between internal subsystems of the embedded controller and external subsystems the controllers interacts with to integrate various types of software. A method includes generating test support models for one or more subsystems and establishing a communications network between the test support models and a control module of the embedded controller. A clock signal is generated to initiate processing within the testing architecture between the control module and the test support models. An event model is executed at the test support models using the clock signal and data is generated at one or more of the test support models responsive to the event model. The data can correspond to operational parameters of a respective system the embedded controller.

Abstract: A method for measuring a large shaft rotation angle utilizes one or more cams attached to the shaft. Each cam shape is designed to have one or more detectable harmonics when rotated. Multiple harmonics in a single cam or amongst multiple cams may have a particular order. Pairs of fine position sensors, positioned at opposing sense angle positions relative to the cam(s) measure displacement of the cam during rotation. The data from the position sensors is then analyzed, with a processor, to determine the large shaft rotation angle and angular displacement relative to an ideal axis of rotation.

Abstract: A power-producing device, such as a ram air turbine, includes a controller that is used to control operation of a turbine of the power-producing device. The controller uses an input based on an airspeed of the aircraft as part of a control mechanism in the controller for controlling the turbine. For example controller may be used to control backpressure of the turbine, for example by controlling the angle of doors of that are used to adjust backpressure of the turbine. The control mechanism may include a PID controller, with the gain of one or more of the values of the PID controller being a function of the airspeed of the aircraft. In addition the control mechanism may include manipulating a setpoint as a function of load on the power-producing device. The power-producing device may be part of a detachable pod that is installed on the aircraft.

Abstract: An apparatus for developing a latent image recorded on a movable imaging surface, including: a reservoir for storing a supply of developer material including toner particles, the reservoir including a developer material mixing and transport area; a donor member being arranged to receive toner particles from the reservoir and to deliver toner particles to the image surface at locations spaced apart from each other in the direction of movement of the imaging surface thereby to develop the latent image thereon; and a climate system, associated with the reservoir, for maintaining the supply of developer material at a predefined temperature, the climate system includes a cooling element for supplying cool air to the developer material mixing and transport area, and a heating element positioned within air path for heating air to predefined temperature.

Abstract: A method and apparatus are provided to control the atmosphere inside of a xerographic control module of an image forming device so that a dew point condition is not reached. The parameters of the atmosphere within the xerographic chamber which are controlled include pressure, temperature and humidity.

Abstract: A liquid crystal display unit is provided which includes a primary, image-defining display and a secondary display, arranged in series with the primary display. The primary and secondary displays have equal numbers of light shutters, similarly sized and located on each display, so that when the corresponding light shutters on the primary and secondary displays are closed, substantially no light passes through the viewing side of the primary display. An opaque mask is formed on the input side of the primary display to define the shape of the image elements to be displayed. This mask covers the edges of the primary display light shutters to define the image elements display. This mask permits the primary and secondary displays to be easily aligned with each other. Color patches can be located on the light input side of the primary display light shutters so that the viewed images are in color. The use of the opaque mask to form the image elements eliminates the need to form precisely shaped color patches.

Abstract: A liquid crystal display unit is provided which includes a primary, image-defining display and a secondary display, arranged in series with the primary display. The primary and secondary displays have equal numbers of light shutters, similarly sized and located on each display, so that when the primary and secondary displays are placed in series their respective light shutters are also in series. When corresponding light shutters on the primary and secondary displays are closed, substantially no light passes through the displays to the opposite side of the primary display. An opaque mask is formed on the input side of the primary display to define the shape of the image elements to be displayed. This mask covers the edges of the primary display light shutters to define the image elements such that each light shutter on the secondary display is larger in size than its corresponding image element on the primary display. This permits the primary and secondary displays to be easily aligned with each other.
