  • Patent number: 5146067
    Abstract: A prepayment system for dispensing utilities using mag-stripe cards is disclosed wherein an accounting computer in a central office is used in conjunction with point-of-sale machines for encrypting a value message which is written onto the mag-stripe of a mag-stripe card. The value message contains information relating to the amount of utilities purchased by the customer, the utility rates, the site identification number, and a unique password formed by the site number, a hidden number, and the transaction number. The mag-stripe card is carried by mail or in person to the consumer's home or office and inserted into a mag-stripe card reader attached to microprocessor-based utility control device. This utility control device is capable of reading and decoding the mag-stripe card and storing the value information into memory for use in monitoring the utility usage of the customer and disconnecting or connecting the utility based on the amount of utilities purchased.

  • Patent number: 5142129
    Abstract: A passbook transporting or conveying mechanism has front gripping rollers for gripping the passbook in unprinted areas thereof and for moving the passbook to a printing station. The front gripping rollers are caused to be moved along guide rods in a rearward direction by driving wires or cables connected to roller supports. The passbook is received by rear gripping rollers which are caused to be moved along guide rods in a further rearward direction by driving wires or cables connected to roller supports to a predetermined position for reading a magnetic stripe on the back cover of the passbook. The magnetic stripe on the passbook is read out and the passbook is moved forward to position the passbook at the printing station for the printing operations on the desired print line or lines. After the printing operations, the passbook is again moved rearward to record the printed information in the magnetic stripe.

  • Patent number: 5142130
    Abstract: A bar code reading system produces a binary signal from an analog signal containing a bar code signal, and demodulates the binary signal into numerals. The bar code reading system includes an amplitude increase detector for detecting when the amplitude of the analog signal steeply changes, and a sequence controller for controlling an output of a demodulator that demodulates the binary signal into numerals. When the amplitude increase detector provides a detected signal, the sequence controller carries out its controlling task as if the bar code has a normal white margin, even if the white margin produces noise. This system correctly recognizes the start of the bar code irrespective of noise and enables a lower limit level thereof to be lowered.

  • Patent number: 5140142
    Abstract: A bar code reading arrangement. A laser beam is scanned across a bar code which may be on a remote surface. Two detectors receive light reflected from the bar code, and convert it to an electrical signal. The detectors are laterally spaced on opposite sides of a line defined by the bi-section of the triangular area which is scanned by the laser beam. The electrical signal from the detector receiving only diffusely reflected light is used to identify the content of the bar code. The invention may be practiced in a hand-held unit with trigger means to initiate the bar code reading operation.
