A lift fan (100) for use in short takeoff and vertical landing (STOVL) aircraft is disclosed and claimed. The lift fan (100) is driven by bleed air from a main engine of the aircraft being directed through an inlet (20) to fan tips (28) within a slot (48) in a housing (12), and may be stabilised in rotation by an electromagnet (50) or a polytetrafluoroethylene (PTFE) coating (92) within the slot (48). This eliminates the drag and torque on the main engine and reduces fuel cost and engine wear.

The image processing system includes a wavelet enhancement component configured to normalize each pixel of each of the sequential frames of image data and to decompose the normalized image data into a plurality of wavelet frequency bands. The image processing system also includes a video processor configured to convert the plurality of wavelet frequency bands in the sequential frames into respective visible color images. The system also includes a video display system configured to display the visible color images.


A laser diode array having submounts allowing thermal transmission from laser diode bars to a heat exchanger while electrically isolating the laser diode bars from the heat exchanger. The laser diode array has a plurality of laser diode bars supported by a corresponding plurality of submounts. Each of the submounts has a submount core having a top surface, an opposite bottom surface and side surfaces. An electrically conductive layer covers part of one side surface. The conductive layer is in electrical contact with one of the laser diode bars. Another electrically conductive layer covers part of a second side surface. An electrical connector connects the electrically conductive layers on the side surfaces. The electrically conductive layers leave an exposed area of the side surfaces adjacent to the bottom surface. The heat exchanger is in thermal contact with the bottom surface of each of the submount cores.

A method and apparatus for embedding critical data directly onboard a physical asset is disclosed. Since the critical data and the asset are never separated, accurate and timely data pertinent to the asset travels with it, and may be written, read, and updated. Accurate data collection ensures a digital model/twin of the asset reflects the true physical state of the asset. Data is embedding optically or magnetically and may be read or rewritten so that information about the life/usage of the asset is continually available, right up to the current state.


The invention relates to a controller (200) for controlling a rotation rate sensor, having a first control circuit (202) and a second control circuit (204). The first control circuit has a first control unit (210) for controlling an oscillation of the rotation rate sensor along a first direction, a first digital-to-analog converter (240) for converting a first digital control signal (215) output by the first control unit (210) into a first analog signal (245) with which the oscillation of the rotation rate sensor along the first direction is controlled, and a first analog-to-digital converter (250) for converting a first analog measurement signal (235) which describes the oscillation of the rotation rate sensor along the first direction into a first digital read-out signal (255) which is supplied to the first control unit (210). The second control circuit (204) has a second control unit (220) for controlling an oscillation of the rotation rate sensor along a second direction which is different from the first direction and a second digital-to-analog converter (270) for converting a second digital control signal (225) output by the second control unit into a second analog signal (275) with which the oscillation of the rotation rate sensor along the second direction is controlled. During the conversion process, the first digital-to-analog converter (240), the second digital-to-analog converter (270), and the first analog-to-digital converter (250) each operates using a reference voltage (241, 251, 271), and at least two of the reference voltages (241, 251, 271) of the first digital-to-analog converter (240), the second digital-to-analog converter (270), and the first analog-to-digital converter (250) are dependent on each other.

A user interface device and method for biometric information processing in a user interface device for biometric collection, quality checking, and matching are disclosed. Embodiments provide a user interface device for capturing biometric information (such as fingerprints) of a subject, determining the quality of the captured biometric information, and comparing the captured biometric information to stored biometric information for possible matches. Comparisons using high quality captured biometric information result in quicker and more accurate verification of identities.
