Abstract: A head mounted display (HMD)-based training tool includes a HMD, sensor components, and electronics components. The sensor components include an external environment sensor for obtaining data of a real training scene. The electronics components include a simulator including at least one processor coupled to receive the real training scene data. The simulator generates virtual image data based on simulator input signals, where the virtual image data represents at least one virtual object. A display device is coupled to receive the virtual image data from the simulator. A field of view (FOV) of the HMD includes the virtual object from the display device and a real-world view of the real training scene, wherein the simulator modifies the virtual image data responsive to changes in the simulator input signals.

Abstract: A motion command is constructed based on an optimized acceleration pulse designed to control the spectral content of the commanded acceleration. By way of judicious design of the pulse shape, the majority of the energy in the command is contained in a narrow baseband and rolls off rapidly in frequencies outside that band. Additionally, the command can be constructed to suppress selected frequency content in one or more attenuation bands outside the baseband. The resulting motion command permits rapid motion control, while avoiding the excitation of unwanted resonant response in the system while remaining tolerant of system uncertainty.

Abstract translation: 基于设计用于控制指令加速度的频谱含量的优化加速度脉冲来构造运动命令。 通过对脉冲形状的明智设计，命令中的大部分能量被包含在窄基带中，并在该频带之外的频率中快速地滚降。 另外，该命令可被构造为抑制基带外的一个或多个衰减频带中的选定频率内容。 所产生的运动命令允许快速运动控制，同时避免系统中不需要的共振响应的激发，同时保持系统不确定性。

Abstract: The present invention is a serviceable fabric assembly for a convertible roof of a motor vehicle having a retainer connected to a fabric cover and slidably engaged within a channel formed in a first bow member. The first bow member has an upper panel and a lower panel configured to form the channel substantially along the longitudinal length of the first bow member. The channel is configured to laterally receive a compressible portion of the retainer which prevents the retainer from exiting the channel in a direction transverse to the longitudinal axis of the first bow member. A gap is formed near at least one end of the channel on the outboard side of the channel and is sized such that an operator can slide the retainer out of the channel through the gap for servicing and replacing the fabric cover without having to disassemble the first bow member.

Abstract: An optical cross connect, especially a wavelength cross connect, using free-space optics, a diffraction grating, and a micro electromechanical systems (MEMS) array of movable mirrors. A concentrator receives light from widely separated optical fibers and brings the beams together into a more closely spaced linear array. Free-space optics process all the beams. Front-end optics collimate the beams from the fibers and flatten their fields. The diffraction grating spectrally separates each beam into sub-beams. A long-focus lens focuses the sub-beams onto the 2-dimensional MEMS array. A fold mirror reflectively couples two such mirrors, whereby the switched signals propagate back through the same optics and are spectrally recombined onto the fibers. Other embodiments include white-color cross connects, multiple MEMS arrays, and parallel optics. Power dividers or wavelength interleavers can divide signals from the fibers, and multiple cross connects switch different wavelength groups.

Abstract: A dynamic power equalization module (10) for an optical network is provided. It includes a module input (16) for receiving an optical transmission (14) containing a combination of different channels (C1-Cn). Each channel (C1-Cn) has a different characteristic wavelength (&lgr;1-&lgr;n) and different varying power. A power equalization device that is polarization insensitive is connected between the module input (16) and a module output (20). The power equalization device is driven by RF acoustic signals (26). A feedback loop (22) receives at least a portion of output from the module output (20) and generates, based upon a comparison of relative powers of the different channels (C1-Cn), the RF acoustic signals (26) which drive the power equalization device. The power equalization device is driven such that it dynamically controls transmission of the different channels (C1-Cn) to substantially equalize power differentials therebetween. The power equalization device includes a parallel array of acousto-optic modulators (AO1-AOn).

Abstract: A three-dimensional texture is mapped onto a graphically-displayed surface by interpolating locations for elements of the texture using an associated distance relationship which locates the element with respect to the surface and a reference location spaced a distance apart from the surface. A first array of points representing the surface are stored, each of the points having an element of the three-dimensional texture and a distance to the element associated therewith. Upon a command to move the displayed surface, a new location for each point of the first array is computed, to obtain a second array representing the moved surface. A location for each element of the three-dimensional texture associated with each point of the first array is interpoled from the corresponding point in the second array and a reference location spaced apart from the moved surface.
