  • Patent number: 5448606
    Abstract: A Gray code counter is provided having identical modular circuits with each odular circuit providing a Gray code count sequence having a predetermined number of bits and an enable signal to enable a successive modular circuit of the Gray code counter. Each modular circuit of the Gray code counter enables a successive modular circuit only during certain predetermined counts of the Gray code count sequence. The number of modules required to implement the counter is determined by the number of binary bits per module and the total number of binary bits provided by the counter. The Gray code counter can operate either in an up mode count or a down mode count in accordance with the Gray code count sequence.

  • Patent number: 5355396
    Abstract: A method and circuitry are provided for modularized single transition counting. A count signal is provided on a count line (436). A single transition count is modified in response to the count signal. The single transition count has a plurality of bits (418, 416) provided by at least one first module (404) and at least one second module (406). The first (404) and second (406) modules are alternately coupled in series to an input module (402) so that one (404) of the first and second modules has an input (460a, 466a) coupled to an output (420, 468) of the input module (402) and so that each additional one (406) of the first and second modules has an input (482a, 488a) coupled to an output (472a, 478a) of an associated one (404) of the second and first modules, respectively.

  • Patent number: 4680454
    Abstract: An odometer for use by a golfer in the measurement of distance covered by each shot. The odometer attaches to the wheel of the cart and counts revolutions or parts of a revolution of the wheel through the use of a magnetic head that rotates past a Hall effect sensor. A digital readout indicator displays yards covered.

  • Patent number: 4562306
    Abstract: A method and apparatus are provided for protecting computer software using an active coded hardware apparatus which is adapted to be connected by an interface connector to a communications port of a computer. The computer is directed by a coded software program in which a small section of the code of the computer software interrogates the communications port periodically to determine if the active coded hardware device is present and connected. The active coded hardware device has a permanently established preset code on an active presettable counter circuit which code is transmitted when interrogated. If the active coded hardware device is present when interrogated and the correct code returned through the communications port of the computer, the program is permitted to continue insuring that the software is properly protected at all times. The active coded hardware device with its particular code and circuitry are sealed in epoxy as a deterrent against tampering.

  • Patent number: 4519088
    Abstract: A usage control system for copiers and the like, adapted to connect to the copier through the existing accounting system connection. A check-operated device, such as a coin box or magnetic card reader, supplies the copier with a signal to initiate operation. When the operation has progressed, the copier supplies a signal intended to increment the counter in the accounting system. After a suitable delay, permitting completion of the copy cycle, the operate signal is reset, and the copier is disabled. As an option, power to the copier may be controlled. The system requires no internal connections or modifications to the copier.

  • Patent number: 4480311
    Abstract: This invention relates to a digital radiation dosemeter comprising a detector (12) converting the ionizing radiation to electrical impulses and an electronic survey device (14) for the storage of said impulses in a dose radiation counter (18). An optoelectronic transmitter (34, 38, 40) sends the informations to an external data processing system. A binary counter (42) operates said transmitter and cooperates with a reading control circuit (43)including a photosensitive receiver (44)connected in series with a magnetic reed switch (46).

  • Patent number: 4458142
    Abstract: A miniaturized card unit, resembling a standard credit card, incorporates solid state counter, a multiplexer means, and a small battery. The counter may be incremented or decremented in accordance with a direction control signal. A multiplexer in the card unit is releasably engageable with the demultiplexer provided in a card reader unit. Control signals, simultaneously applied to the multiplexer and demultiplexer transfer the count stored in the card unit to decoder driver circuits which drive a display for visually displaying the decimal count stored in the card. A logical circuit monitors selected segments of the display to enable operation of the device controlled by the card reader unit so long as the card inserted therein contains a non-zero count. The logical circuit prevents operation of the device upon the occurrence of a zero count as well as the absence of a card unit.

  • Patent number: RE32226
    Abstract: .[.An electronic franking machine, for example a postal franking machine, has a digital electronic input register, for storing a selected franking value fed in for use in the next franking operation of the machine, and a digital electronic total register which accumulates an indication of the total of the respective franking values used for such operations of the machine since this register was last reset. The machine also has an electrically adjustable printing device, for printing the selected franking value in each franking operation. The printing device is housed in a relatively massive stationary unit of the machine, and the electronic registers and associated circuitry are housed in a relatively light portable unit that is readily separable from the stationary unit to facilitate resetting by a remote authority..]..Iadd.
