Abstract: A reproduction equalizer (2 to 6) including a linear equalizer (11) for linearly equalizing a source signal read from a recording medium, a nonlinear cancellation means for cancelling an intersymbol-interference (ISI) contained in the reproduction signal, a decoder (17;22, 24;26) for decoding the ISI free signal to reproduce a digital signal prior to storing into the recording medium and means (18) for automatically calculating and/or updating the ISI data held in the nonlinear cancellation means on the basis for the equalized source signal (X[k]) for each address defined by the reproduced digital signal (A[k']). The nonlinear cancelling means includes a lookup table (14) storing the ISI data, a circuit (12,13) for generating an address ({A}) for reading out the ISI data from the lookup table, and a circuit (16) for subtracting the read ISI data from the equalized source signal. At an initial stage, the calculation means (18) calculates the ISI data, and in a normal operation mode, the calculated ISI data is used.

Abstract: Font-independent spotting of user-defined keywords in a scanned image. Word identification is based on features of the entire word without the need for segmentation or OCR, and without the need to recognize non-keywords. Font-independent character models are created using hidden Markov models (HMMs) and arbitrary keyword models are built from the character HMM components. Word or text line bounding boxes are extracted from the image, a set of features based on the word shape, (and preferably also the word internal structure) within each bounding box is extracted, this set of features is applied to a network that includes one or more keyword HMMs, and a determination is made. The identification of word bounding boxes for potential keywords includes the steps of reducing the image (say by 2x) and subjecting the reduced image to vertical and horizontal morphological closing operations. The bounding boxes of connected components in the resulting image are then used to hypothesize word or text line bounding boxes, and the original bitmaps within the boxes are used to hypothesize words. In a particular embodiment, a range of structuring elements is used for the closing operations to accommodate the variation of inter- and intra-character spacing with font and font size.

Abstract: Recording of exposure data in a photographic camera (10) in correspondence with a picture frame includes activating a flash (24) to provide illumination for exposing the picture frame onto a photographic film. Sensing (26) is performed to determine if light generated by the flash is reflected from a subject in the picture frame. Data is recorded (28) in association with the picture frame indicating if reflected light is sensed. In accordance with a method of operating a photographic printer (46) to print a negative frame (42), the reflected flash illumination data associated with the negative frame is read (50). An appropriate exposure for the negative frame is selected based at least in part on the presence or absence of the sensed reflected flash illumination.

Abstract: An ink-jet printer (50) having improved print quality and full color printing capability on plain paper media. To accommodate placement of both input and output media trays (54, 56) on the same side of the printer housing for operator convenience, a paper path with a direction reversal is employed. A paper preconditioning preheater (72) with a curved surface and a multi-purpose paper path component (70) accomplish the direction reversal. As the print medium is driven through the paper path, it contacts the preheater (72). The preheating dries and shrinks the paper to condition it for the printing operation. The preheater is a thin flexible film carrying heating elements (122, 128), and is suspended in air, to provide extremely low thermal mass and eliminate the need for long warmup times. The preheater defines a first, hotter, preheating area (130) adjacent the printing area, and a second, cooler, preheating area (124) separated from the printing area by the first preheating area.

Abstract: The invention relates to a sound emission transducer and to a coupling method. The sound emission transducer (1) forms an assembly unit and is especially designed for the measurement of high-frequency sound emissions (up to about 2MHz). It consists of a piezoelectric measuring element (9), a sound transmitting base (8) with a circumferential coupling diaphragm (7) and a cast compound (10) partially enclosing the measuring element (9). A mounting screw (3) is used to fasten the transducer. The coupling diaphragm (7) is located in a step (14) of the housing (2), whose bottom surface (5), in the case of an unstressed diaphragm (7), has a spacing from the object to be measured corresponding to the elongation (s) (15). The coupling of the sound emission transducer (1) to the object to be measured (15) is carried out such that the bottom surface (5) is pressed onto the object to be measured (15) by tightening the screw (3) and is fastened to the object, as a result of which the diaphragm (7) is stressed and the mounting base (8) is coupled to the surface of the object to be measured (15). The invention enables miniaturisation and more efficient production of the transducer and an improvement of the high-frequency sound transmission. <IMAGE>

Abstract: A method of analysing a communication system to locate the source of a fault. The communication system comprises a signal carrying medium (9) coupled to a series of end station ports (2-6) which enable respective end stations (24) to transmit signals onto and receive signals from the medium and a controller (8) to control connection of end stations (24) to the medium via the ports (2-6). The method comprises disconnecting end stations (24) in series from the medium (9) in response to detection of a fault and then detecting whether the fault still exists. A fault analyzer (10) adapted to respond to the detection of a fault causes the controller (8) firstly to disconnect an end station (24) which has previously been characterised as the most likely source of a fault. The controller (8) may disconnect groups of end stations (24) and reconnect subgroups if no fault is present in the group which was not disconnected until the faulty end station is identified.
