  • Patent number: 9152836
    Abstract: The present invention discloses a code scanning device including a code scanner, a supporting member and a data processing and controlling unit. The unit is configured for receiving data information of a scanned code and determining whether or not the data information is correct. If correct, the unit stops scanning of the code scanner and controls the supporting member to move so that a next code is shifted to a scanning position. Wherein when the data information is incorrect or the unit fails to receive data information, the unit controls the code scanner to keep on scanning, and when scanning time exceeds a second predetermined time and the unit fails to receive correct data information, the unit stops scanning and controls the supporting member to move so that a next given code is shifted to the scanning position. The scanning device has an improved scanning speed and a high scanning reliability.

  • Patent number: 8190280
    Abstract: A method and appertaining system implement the use of manufacturing protocols for hearing aid design such that the ability to build an instrument can be displayed as a numeric parameter based on the partial numerical and metrological contributions of all the essential parameters of the given impression, and a buildability index can be displayed as a 3D virtual image of the proposed shell or preferred shell types. The method utilizes a predefined parameter table comprising parameters to utilize for a buildability determination. The buildability index is computed based on impression shape data, selected shell type, selected number of device options, data obtained from the parameter table, and data obtained from a receiver table, and the buildability index is output to a display of a user interface device or an external system.

  • Patent number: 8179568
    Abstract: What is disclosed is a novel system and method for minimizing dot visibility in color marking devices capable of dot-on-dot printing. The present method achieves minimum dot visibility for a given dispersed-dot screen by performing a CMYK to CMYKRGB conversion which uses less visible dots as much as possible before more visible dots are introduced. The output color dot coverages are calculated sequentially to minimize the coverage of more visible dots in a decreasing order of brightness. Resulting images have noticeably reduced halftone graininess, particularly in the mid to darker tone areas. The present method is also computationally efficient.

  • Patent number: 7605812
    Abstract: A method and appertaining system are provided for automatically modeling a hearing aid sheet design. A 3D geometric description of an undetailed shell model is received, and its features and associated descriptors are automatically extracted. These features are classified, and a database of existing shells and features is queried to determine if a stored shell model matches the received shell model or if stored features match one or more of the extracted features. If matches are found, then specific rules are implemented that have been previously stored and associated with the matched shell model or features on the received shell model. If no matches are found, then generalized binaural modeling rules are utilized based on the classified features.

  • Patent number: 7562825
    Abstract: In an apparatus, a collimated-beam irradiating unit irradiates on the target a substantially collimated beam with a size thereon. A first pickup unit causes the photodetector to pick up through the imaging optics a first image of the target while the substantially collimated beam is being irradiated on the target by the collimated-beam irradiating unit. A measuring unit measures size information indicative of the size of the collimated beam being irradiated on the target based on the picked-up second image. A distance determining unit determines a distance between the apparatus and the target based on the measured size information of the collimated beam.

  • Patent number: 7519213
    Abstract: In an apparatus for processing banknotes or other sheet-like objects, the banknotes are conveyed along a transport path, thereby passing sensor means. A transmission and a reflection image of the banknote are captured by illuminating the banknotes and measuring the transmittive and reflective light intensity of light with a high resolution. Based on these images, a validation of the banknotes is carried out. After the validation, a double feed detection is performed by evaluating the transmission and the reflection intensities for a predefined set of test spots with a two-dimensional evaluation. If it is decided on double feed, the banknotes are rejected. Otherwise the banknotes are accepted and further processed. Because of the additional dimension in the evaluation compared with known double detection methods, the invention enables a more robust double note detection also in cases with different degrees of soiling of the banknotes.

Of diffracted lights diffracted by the diffracting surface when the surface to be scanned is scanned by the beam, relative to diffracted light of an order used to form a spot on the surface to be scanned, the expanse of the stray light of one of unnecessary diffracted lights of the other orders undergoing surface-reflection by a refracting surface of the imaging optical system upon incidence on the surface to be scanned is designed to be wider in the sub-scanning direction than in the main scanning direction.

  • Patent number: 6917710
    Abstract: A scanning system and method for scanning for an object within a region, or for locating a point within a region. Embodiments of the invention include a method for scanning for an object within a region using a Low Discrepancy Curve (LDC) scanning scheme. The method may: 1) generate a Low Discrepancy Sequence (LDS) of points in the region; 2) calculate an LDC in the region based on the LDS of points; and 3) scan the region along the LDC to determine one or more characteristics of the object in response to the scan. In calculating the LDC in the region based on the LDS of points, the method may connect sequential pairs of the LDS with contiguous orthogonal line segments (each parallel to a respective axis of the region), then sample the segments, generating points which may be used to generate the LDC, such as by a curve fit.

  • Patent number: 6288794
    Abstract: A variable sample rate converter, adaptable to rational ratios, converts a plurality of data having a first sample rate to a plurality of data having a second sample rate. The variable sample rate converter is employed in data processing devices including, for example, color photo-copy machines, color facsimiles, color printers, black and white printers, digital cameras, and digital printers. A finite impulse response filter is employed to perform processing of the plurality of data. Any processing hardware capable of performing floating point processing may employ the variable sample rate converter. A ping-pong style buffer is employed to assist in transferring the plurality of data. The variable sample rate converter combines the two steps of up-sampling and down-sampling into a single step, thereby maximizing available processing resources.

  • Patent number: 6101266
    Abstract: An apparatus and method for providing an indication of a type and/or a condition of a note passing through the apparatus includes a note transport (12) which moves the note past transversely spaced spot sensing assemblies (18). Each spot sensing assembly includes four emitters (32). Each of the emitters produces radiation at different wavelengths. The spot sensing assemblies include a reflectance detector (20) and a transmission detector (22) which are disposed on opposed sides of the passing note. The emitters direct radiation onto test spots (34) on the passing note. Radiation reflected from and transmitted through the test spots is detected by the respective reflector and transmission detectors. A control circuit (24) produces sensed values that correspond to the detected radiation. A data store in operative connection with the control circuit comprises memories (138) that include stored data representative of transition and reflectance values for know note types.
