摘要： A video camera generates an approximation of the dark current or black shading distortion signals based on scan position in the image, and subtracts the approximation signal from the signal generated by the camera during normal image-sensing operation to reduce the black shading distortion. In a particular embodiment of the invention, counters generate location signals representative of the location of pixel currently being read, and the location signals are processed by functions such as squaring or raising to a constant power, and by weighting, to produce components of the approximation of the dark signal. The components are subtracted from the imager signal, to reduce the dark shading. In one embodiment of the invention, the functions are automatically selected from among a plurality of preselected functions, and implemented by look-up tables.

摘要： A content addressable memory (CAM) system, is disclosed for writing data including a key portion and an extended portion, and for reading the extended portion in response to the match of a search key a key portion of the data. The system includes a conventionally addressed RAM, organized into segments, each segment of which is identified by a starting address. It also includes a CAM, also organized into words. Each of the words of the CAM is identified by a CAM address. Data to be written into the memory includes a key portion and an extended data portion. The key portion of the data is written into the CAM at a selected address, and the extended data portion is written into a segment of the random access memory which begins at an address determined from the selected address. Data in the random access memory is read by searching the CAM for a search key and then using address of matching entries found in the CAM to generate address values for the random access memory. The random access memory is then addressed to fetch the extended data associated with each of the matching entries. In one exemplary embodiment, the memory system is used to hold a database of television programs in a cable television scheduling system.

摘要： A signal processing system for a video camera uses a single neural network to implement multiple nonlinear signal processing functions. In one example, the neural network implements gamma correction and contrast compression, in another example, color correction and aperture correction are added to the combined function emulated by the network. The network is trained using back propagation to emulate one function then a combination of two functions, then a combination of three functions, and so on. The programmed neural network replaces multiple pipelined signal processors in the video camera. The use of a single neural network in place of the multiple dedicated processing functions reduces engineering effort to develop the product and may reduce the cost of the total system.

摘要： This invention includes a speech training system that allows a student to enter any utterance to be learned and have the articulatory model movements required to produce the utterance displayed on a CRT screen. The system accepts a typed utterance, breaking it down into a set of phonemes. The set of phonemes is sent to a synthesizer, which produces a set of parameters indicating the acoustic characteristics of the utterance. The acoustic parameters are converted into articulatory parameters emphasizing the frequency, nasality, and tongue-palate contact required to produce the typed utterance. The articulatory parameters are displayed on the CRT screen. The acoustic parameters are also sent to a formant synthesizer which converts the parameters into speech output. The system measures a student's production and then evaluates the student's production against the parameters of the typed utterance for its similarity. Feedback on the similarity is displayed on the CRT screen.

摘要： A method for analyzing a speech signal to isolate speech and nonspeech portions of the speech signal is provided. The method is applied to an input speech signal to determine boundary values locating isolated words or groups of words within the speech signal. First, a comparison signal is generated which is biased to emphasize components of the signal having preselected frequencies. Next, the system compares the comparison signal with a threshold level to determine estimated boundary values demonstrating the beginning and ending points of the words. Once the estimated boundary values are calculated, the system adjusts the boundary values to achieve final boundary values. The specific amount of adjustment varies, depending upon the amount of noise present in the signal. The final pair of boundary values provide a reliable indication of the location and duration of the isolated word or group of words within the speech signal.

摘要： A video signal processing system uses a sequence of interpolation filters to resample a 125M video signal to produce a 244M signal. In addition, the system allows an operator to specify a desired subcarrier-to-horizontal sync (SCH) phase and a desired horizontal position. The system automatically adjusts the starting point in the sequence of filters used for the resampling operation to implement each of the requested phase shifts.

摘要： A method of manufacturing a precision micro-filter and a micro-filter manufactured thereby is disclosed. A micro-mold is manufactured using micro-machining technology (such as micro-electrical-discharge machining technology, laser-beam micro-machining, electron beam micro-machining) to make a filter mold with a plurality of rod-like protrusions, of the shape, dimensions, and spacing required for the pores of a finished micro-filter. A molding material is placed into the micro-mold, the molding composition is allowed to solidify to form a micro-filter, the passageways of which conform precisely to the rod-like protrusions of the mold. This micro-filter is then separated from the micro-mold.

摘要： A transport system allows delivery of MPEG video streams from a network server to a media client while avoiding network delays associated with transition between files contained in these streams. A buffering system, a transport controller, and a counter allow buffering and interim delivery of MPEG stream data. The transport controller can either deliver MPEG stream data directly to the media client, or route data through the buffering system. The buffering system includes a population buffer for storage of interim MPEG stream data, and a transport buffer for temporary storage of MPEG stream data during continuous delivery. During transitional delivery, the transport controller delivers interim data to the media client until the requested file is available and uses the counter to select the proper start location in the requested file.

摘要： The distributed multimedia server employs modular server elements that connect with client systems through a high bandwidth network. The server elements are connected in interleaved fashion with the switching elements and the data representing different media selections are arranged in stripe groups distributed across the server elements. The server can be as small as a single server element or grown incrementally, as needed, by connecting additional server elements to the system. Multiple copies of hot media selections are stored across the distributed architecture within different stripe groups to minimize bottlenecks within the storage subsystem.
