  • Patent number: 8113428
    Abstract: Optical reading system and methods having multiple modes of operation, for example: omnidirectional and single-code picking; fixed and handheld reading; 1D and 2D code reading. In one configuration, an image-based system obtains input data via an area sensor (e.g., a 2D CCD array) with only data corresponding to a pattern of virtual scan lines being stored and processed. A user may implement different operating modes such as a first mode reading codes in any location or orientation and a second mode reading only a code oriented along a particular virtual scan line or group thereof. Alternately, the data reader is operable to switch between handheld mode selecting a first pattern of virtual scan lines to process and/or decode and a fixed mode selecting a second pattern of virtual scan lines to process and/or decode. Virtual scan patterns in either mode can change within or between frames.

  • Patent number: 7971790
    Abstract: A laser pointer includes a human-machine interface disposed above the housing for users to control components inside the housing to decide patterns and size of the projecting image. The components consist of a frequency/phase control module, a driving energy control module, a laser beam generating module and a light scanning device. The frequency/phase control module controls the driving energy control module while the driving energy control module controls driving energy of the light scanning device. The size of the image is controlled by change of the amplitude of the light scanning device while the amplitude is changed along with the driving energy. The amplitude may also change along with the driving frequency. When the driving energy is fixed and the driving frequency is close to the resonant frequency, the amplitude increases. On the contrary, the amplitude decreases.

  • Patent number: 7942329
    Abstract: An optical barcode and/or RFID reader having at least two sets of illuminating LEDs that are directed toward a target object to reflect whether the barcode and/or RFID reading was successful or unsuccessful. The reader is provided with a set of red LEDs and a set of green LEDs for illuminating targets, such as barcodes or RFID tags. In addition to using these LEDs to illuminate the target, the reader will illuminate the target with a particular color of light to signify a successful read, such green light, or an unsuccessful read, such as red light. A third color may be provided to indicate a successful RFID interrogation, such as blue light. The reader thus uses the built-in illumination LEDs to cast differently colored light on the target, rather than having to provide additional LEDs in a user interface positioned on the housing of the reader.

  • Patent number: 7823785
    Abstract: Provided is a planar light source device (300) having a planar light source with uniform luminance distribution by using a laser light source for outputting a beam-like luminous flux. The planar light source device (300) applies a laser beam from the side surface of a light guide plate (310) through a scanning mirror (330) and periodically scans the entire light guide plate. At that time, a light output (P(t)) of the laser light source (320) is modulated in synchronization with the scanning cycle so that the output is proportional to the temporal differentiation dS/dt of a scanning area (S(t)) from a search start within a scanning period. Thus, changes of the scanning speed and scanning length with time are eliminated and planar lighting with uniform luminance can be performed.

In one configuration, an image-based system obtains input data via an area sensor (e.g., a 2D COD array) with only data corresponding to a pattern of virtual scan lines being stored and processed. A user may implement different operating modes such as a first mode reading codes in any location or orientation and a second mode reading only a code oriented along a particular virtual scan line or group thereof. Alternately, the data reader is operable to switch between handheld mode selecting a first pattern of virtual scan lines to process and/or decode and a fixed mode selecting a second pattern of virtual scan lines to process and/or decode. Virtual scan patterns in either mode can change from frame to frame.

  • Publication number: 20100019041
    Abstract: An operator is guided to move an imaging reader to an optimum reading position in which to read a symbol by image capture. Optimum image capture occurs substantially at an imaging plane of an imaging assembly, and the operator is visually guided so that the symbol is located substantially at the imaging plane in a working range of distances.

  • Patent number: 7647198
    Abstract: To facilitate the recognition and interpretation of actions undertaken within an environment, the environment is associated with a precision positioning system (PPS) and a controller in communication with the PPS. Within the environment, an entity moves about in furtherance of one or more tasks to be completed within the environment. The PPS determines position data corresponding to at least a portion of the entity, which position data is subsequently compared with at least one known action corresponding to a predetermined task within the environment. Using a state-based task model, recognized actions may be interpreted and used to initiate at least one system action based on the current state of the task model and correspondence of the position data to the at least one known action. Furthermore, based on the recognized action, the controller may provide information to the entity or captured event data may be associated with the recognized action.

  • 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: 7559470
    Abstract: A positioning controlling apparatus includes: a current speed calculator that calculates a current speed of a conveyor belt from a detected moving distance; a position determining unit that determines the position of a conveyor belt for determining its stop position also from the detected moving distance; a gain switch having a plurality of gains; a target speed calculator that inputs a gain obtained by switching, and calculates a target speed of the conveyor belt; a speed error calculator that calculates an error between a calculated target speed and a calculated current speed; and an automatic controller that controls a drive motor by using a speed error. When the position determining unit determines that the conveyor belt is in the positioning area, the gain switch performs positioning while switching plural gains and outputting it.
