  • Patent number: 11736649
    Abstract: In an image forming device, an image forming engine is configured to form an image. A memory stores configuration information and a device password. In a case where a storage medium is connected to the input output interface, the controller determines whether an authentication skipping condition is satisfied. The authentication skipping condition including a condition that the device password is maintained to an initial value. The controller imports the setting configuration information from the storage medium to the memory without performing authentication using the device password in a case where the authentication skipping condition is satisfied. The controller imports the setting configuration information from the storage medium to the memory after performing authentication using the device password in a case where the authentication skipping condition is not satisfied. After the import configuration information is imported, the controller operates according to the import configuration information.

  • Patent number: 8078113
    Abstract: An adaptive antenna control method is used for a radio communication system built by a plurality of radio base stations and a plurality of terminal stations capable of communicating with the radio base stations. Each radio base station includes an adaptive antenna having a plurality of antenna elements, a distributor for generating signals to be input to the plurality of antenna elements by branching a signal of one system to be transmitted, and weighting circuits for respectively weighting transmission signals to the plurality of antenna elements. For reception by each terminal station, an interference wave power given by the transmission signal from each of the plurality of radio base stations is estimated. A weight in the adaptive antenna of each radio base station is determined to minimize a sum of square errors between reception signals and desired signals for all the radio base stations which simultaneously use the same communication channel.

  • Patent number: 7236199
    Abstract: A camera comprises a multitap imager, separate digitizing channels for each imager tap, adjustments for channel gain and black level, a pattern generator, and a channel balancer. The channel balancer compares adjacent pixels and sums the differences in levels over many frames. Any accumulated difference is used as a feedback signal to drive the summing to a minimum. If the imager is temporarily hooded, the feedback is used to balance black levels between the channels. If the imager is operating, the feedback is used to dynamically adjust the channel gain of one channel to match the other. A pattern generator is used once during calibration to generate a test pattern in the digitizing channels that makes it obvious to a framegrabber how exactly to restitching the various lanes or zones of the whole image frame back together.

  • Patent number: 7133556
    Abstract: A character recognition device to recognize characters in a text image read by an image scanner having a first recognition device to recognize the characters in the text image using a first character recognition method and a second recognition device to recognize the characters in the text image using a second character recognition method different from the first character recognition method. An extraction device extracts locations of recognized characters in the text image wherein the recognition results of the first recognition device do not coincide with the recognition results of the second recognition device. An output device outputs character recognition results designating the non-coinciding locations extracted by the extraction device.

  • Publication number: 20050134711
    Abstract: A CCD video camera system comprises a CCD imaging device connected to a low-gain amplifier. An analog-to-digital converter converts the analog output of the amplifier to a full-range digital video signal. Such addresses a digital look-up table to produce a digital video output according to one of several selectable range-correction curves. Such range-correction curves comprise two linear slopes that join at a knee, and the two linear parts have two different gain slopes. The range-correction curves are selected on the basis of the gain slope of the first of the two linear slopes, and the knee-point.

  • Patent number: 6735182
    Abstract: In an array antenna used in a transceiver in a time division communication system such as TDD (Time Division Duplex) system, amplitude and phase of each antenna element are calibrated in a transceiver itself during actual communication without using external information. A first transmitter (1-3-1) has means (1-5-1) to send a transmit signal to an antenna element (1-1-1) as well as to at least one of the receivers (1-4-1 through 1-4-N). Other transmitter (1-3-2 through 1-3-k) except the first transmitter has means (1-5-k) which sends a transmit signal to a related antenna element (1-1-2 through 1-1-k) as well as to a first receiver (1-4-1) which relates to the first transmitter. Amplitude/phase value obtained in the first receiver (1-4-1) and amplitude/phase values obtained in other receivers (1-4-2 through 1-4-k) except the first receiver provide weighted amplitude/phase values of each antenna elements according to desired desired radiation pattern.

  • Patent number: 6638787
    Abstract: A fast frame-rate imaging device is produced by a attaching a fiberoptic block to an otherwise ordinary and inexpensive CCD. A part of the fiberoptic block is occluded so as to darken a majority of the active imaging photocells. The CCD imaging device is operated at near its maximum horizontal and vertical clock rates, but multiple image frames are defined within the one previous active photocell array field. The added dark areas in the optical field protect the recent frames still in transit within the active array area from being double exposed and thus corrupted. The serial output of the thus-modified CCD imaging device is reinterpreted to include more frames than originally at a multiple equal to the original array dimension divided by the new array dimension (m·n/m′·n′). Such a modified CCD array uses only one-fourth of the original active area, and is operable at a multiple of the original frame rate.

  • Patent number: 6332137
    Abstract: A recognition system comprises at least two field-programmable logic array devices connected to a common vector-input port of an array of a zero-instruction-set computers. Each field-programmable logic array device is configured to preprocess data from different respective media inputs and provide feature extraction vectors to the common vector-input port. Neural networks within the zero-instruction-set computer recognize the input patterns by comparing in parallel their vectors with those stored in each neural network cell. A variety of recognition jobs are made possible by changing the programming on-the-fly of the field-programmable logic array devices to suit each new job.

    Abstract: An adaptive array antenna system for stable directivity control and waveform equalization even under poor multipath environment is provided. An output of antenna elements (A1011-A101n) is weight combined (A103), and is output through automatic frequency control (A106) and fractionally spaced adaptive transversal filter (A107) which have real number weights. Weight combination (A103) is initially carried out with weights for an eigen vector beam for the maximum eigen vector of the correlation matrix Rxx of a receive signal After carrier synchronization and timing synchronization between a receive signal, and an A/D converter and a fractionally spaced transversal filter are established by the automatic frequency control and the fractionally spaced transversal filter, the weight in the weight combiner (A103) is switched to minimum mean square error (MMSE) weight.
