A system utilizes a screen having a compound curvature to simulate an environment viewable from multiple vantage points. The compound curvature of the screen is such that the screen is curved in at least two directions about at least two axes. The display can be positioned behind a wall opening to provide a window effect. The display terminates its active image area outside of a region from which the display can be viewed to create a seemingly infinite simulated environment.

The invention discloses a method and system for browsing different flow chart node through multiple windows, belonging to the field of the visual adjustment software. The method comprises the following steps of: setting a multi-window effect monitor so as to observe the flow chart node results through multiple windows; setting observation points on flow chart nodes, and establishing an associated container used for recording and saving selected nodes and observation point index numbers; obtaining the nodes which correspond to the observation point index numbers from the associated container according to the observation point index numbers; and obtaining the output images of the nodes and displaying the output images of the nodes on an effect monitor. Due to the adoption of the method and the system, the user can brow different flow chart node results as required, and the problem that the user cannot observe conveniently when operating a flow chart is effectively solved.

The invention relates to a method for diagnosing a bearing fault, which comprises the following steps of: (1) acquiring a vibration acceleration signal of a bearing by using an acceleration transducer; (2) acquiring a form spectrum of the vibration acceleration signal by adopting a morphologic closing computation mode; (3) determining parameters of a morphologic structural unit according to the form spectrum in the step (2), and extracting a fault impact sequence; and (4) observing whether an obvious peak is present at a fault characteristic frequency on the form spectrum in the step (2), or observing whether the extracted impact sequence in the step (3) has obvious periodicity and corresponds to the corresponding fault characteristic frequency to judge whether a rotating machine has a fault. By the method, signals are not required to be filtered, and a window effect is avoided. The method is simple and has better adaptability, and the parameters are not needed to be determined in advance. Impact pulses generated due to the bearing fault can be directly extracted, other unrelated information is eliminated, and the method has obvious physical significance. The structure is simple, the computing speed is high, and real-time monitoring can be realized.

The invention discloses plate glass with a three-dimensional effect. The plate glass with the three-dimensional effect comprises a screen lens. A linear diaphragm layer, a light color layer and a black color layer are sequentially printed on the screen lens from top to bottom; grid lines or folding lines are mainly adopted for the linear diaphragm layer; the light color layer is printed on the linear diaphragm layer twice from different angles; the black layer is finally printed on the light color layer; and the grid lines or the folding lines have the lengths of 0.15mm, and have the thicknesses of 5 micro meters. According to the scheme provided by the invention, the linear diaphragm layer, the light color layer and the black color layer are sequentially printed on the screen lens in layers; the design breaks through the intrinsic printing effect; the visual three-dimensional effect is realized through printing different layers; and from the view of effects, different color series are matched with different view window effects, so that the whole plate has vigor and dynamic sense.

The invention provides statistically optimal near-field acoustical holography used for visual recognition of air-conditioner noise sources and an operation method thereof. The operation method comprises the followings: determining the positions, frequency characteristics and distribution ranges of the noise sources, and distance between microphones on microphone arrays, number, sample rates and number of sampling points of microphones; calibrating arrayed microphones; collecting data; recording sound pressure data; processing the sound pressure data; reading the processed data and finally entering noise source recognition procedures. By the invention, complex sound pressure on reconstructive surfaces and vibration velocity of surface particles can be calculated directly via linear superposition of the complex sound pressure on a holographic plane in a spatial domain, thus essentially overcoming window effects and wraparound errors existing in near-field acoustical holography and avoiding the problems brought about by the demand of a large number of microphones by near-field acoustical holography, such as low reconstruction efficiency of sound fields and costly cost of measuring systems, etc. The invention is characterized by small number of demanded microphones, low measuring cost and high reconstruction efficiency of the sound fields.
