  • Patent number: 6102294
    Abstract: A light scanning system formed on a common substrate comprises a light scanner and a sensor. The light scanner scans light across a target. The sensor detects light reflected from the target and creates a signal representative of the detected light. The light scanner may include a light source and a deflector, such as a micro-machined scan module. The micro-machined scan module may comprise an electrode, a support mounted on the electrode, and a mirror element mounted at one end of the support, wherein a voltage applied between the electrode and mirror element bends the mirror element.

  • Patent number: 6102290
    Abstract: A self-check apparatus is provided for processing a sales transaction of an article having an attached surveillance tag, each attached surveillance tag bearing a coded indicia such as a bar code. The self-checkout apparatus stores an indication of the articles which have been selected for purchase. When the surveillance tag is presented to the apparatus for deactivation, the bar code on the tag is scanned, and a check is made to verify that the surveillance tag is attached to an article which has been selected for purchase, and provided such verification is made, the surveillance tag is deactivated.

  • Patent number: 6098881
    Abstract: Magnetic stripe documents are identified and authenticated on the basis of repeatable magnetic characteristics of a stripe recorded with digital data. Stripes are sensed to provide an analog signal, only a portion of which is used, specifically, the portion storing leading zeros. Cyclically, the leading zeros are sampled and digitized as a target number of samples using a frequency locked loop. The target number of samples for each zero is then reduced by a selection process that attains a predetermined number of digital samples that represent a magnetized portion of a leading zero, specifically, a space between data transitions. Groups of selected predetermined number of digital samples are then combined to provide a card magnetic characteristic identifier. Documents are verified by correlating reference and recent characteristic identifiers. Specific forms of sensor structures are utilized for the applications involving multitudes of different documents and sensor structures.

  • Patent number: 6092727
    Abstract: A data reading device for reading digital data encoded in one or a plurality of data-carrying surfaces directs the output from a single wavelength laser diode at the surface of the data carrier, by focusing the light from the laser using an objective lens. The data may be decoded by sensing anomalies in current flow through a precision shunt which is series connected with the laser diode, because light reflected back off the data-carrying surface is re-directed back to impinge on the laser, and the reflected light will cause anomalies in the current flowing through the diode. Alternatively, the reflected light can be deflected using a prism towards a photo-sensor. In either event, the digital data can then be decoded. A pinhole diaphragm is interposed between the laser and the objective lens, or an objective lens assembly, and the pinhole will function as a point source of light. That point source of light can be re-focused with high resolution on the data-carrying surface.

  • Patent number: 6082621
    Abstract: A multi-bit digitizer (30) for a barcode reader detects the presence of edges of a scanned barcode symbol, and also measures the strength of each detected edge. A polarity or edge direction signal (8) indicates the direction of each detected edge, and a timing signal (6) is representative of the timing and also, by means of a variable pulse width, the strength of each edge. A gating signal (200) indicates that the data are unreliable and invalid if the measured voltage applied to the scanner motor of the barcode reader is higher or lower than defined limit values. Any scans made at a speed which were too high or too low are rejected.

  • Patent number: 6079619
    Abstract: An identification tag is attached to or imbedded in each article a plurality of which are located nearby or stacked together. The identification tag wirelessly communicates with a remote controller such as a hand-held terminal to send data or receive command. Electric power to operate the identification card is also wirelessly supplied from the remote controller. The electric power is received only by a particular identification card which is communicating with the remote controller, and is turned off when the communication is completed. The electric power is then supplied to the next identification card which communicates with the remote controller. Thus, all the identification tags sequentially send data thereof one by one to the remote controller. The remote controller includes an indicator that indicates whether the communication with all the identification tags is completed, so that the remote controller can be positioned at a right place until the end of the communication.

  • Patent number: 6062476
    Abstract: A scanning device incorporates a vertical cavity surface emitting laser (VCSEL). The laser diode may be mounted directly on an Si substrate which is adapted for movement to produce a scan pattern. A collimating lens may be directly mounted on the emitting surface of the laser. A plurality of lasers may be mounted on the substrate and operated in sequence without movement of the substrate to produce the effect of a scan. The scanning device emits visible or invisible light towards a target such as a bar code and a detector (mounted on the same or an adjacent substrate) senses the light reflected by the target to produce data which is decoded for further processing. A VCSEL uses low current and emits light from a relatively large area so that a relatively large amount of light is emitted for relatively small heat generation.

  • Patent number: 6059187
    Abstract: Bar with count values indicating widths of white and black bars, which are reciprocally obtained, are input to buffers connected in series at 16 stages. The bar width count values written to those buffers are sequentially shifted each time a new bar width count value is input. A comparing circuit compares the widths of the adjacent bars in the same color with each other and checks whether or not a ratio therebetween falls within a range of 0.2-5.0 times as large as each other. Results of the comparisons by this comparing circuit are written to result registers connected in series at 13 stages. The check-results written to those result registers are sequentially shifted each time a new bar width count value is input. Accordingly, if all the check results written to all the result registers indicate an "in-range" state, it follows that the fifteen or more bars consecutively meet a bar code condition. Hence, the counter lets an AND gate open.

  • Patent number: 6059188
    Abstract: An integrated optical module for an optical scanner has a lens spaced from a vertical-cavity surface-emitting laser (VCSEL) by a spacer of defined dimensions. The module, in an alternative embodiment, includes a wafer frame, a suspended mirror mounted for oscillation on the frame, a wafer substrate bonded beneath the frame and a wafer cover bonded above the frame. The cover includes a mirror travel stop to protect the mirror against shocks. A VCSEL mounted to the wafer cover produces a beam which is shaped and deflected by a diffractive optical element onto the oscillating mirror. The reflected beam passes out of the module toward an indicia to be read. Large numbers of such devices may be fabricated relatively cheaply using wafer-scale processing and assembly technology. Three large wafers are fabricated corresponding respectively to arrays of substrates, frames and covers. The large wafers are bonded together in a sandwich arrangement, and are then diced to produce the individual scan modules.
