Patents by Inventor John P. Heptig

John P. Heptig has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8749368
    Abstract: A system and method for signaling, marketing, and advertising alternative fuel-based vehicles that easily installs into new or pre-existing alternative fuel-based vehicles. In a preferred embodiment, the system comprises an electronic control unit (“ECU”) installed in the vehicle, which determines whether an internal combustion engine or alternative power source powers the vehicle. The system further comprises a driver display and in-car display both of which are connected to the ECU. The ECU monitors the power status of the vehicle and illuminates vehicle displays and transmits a signal to illuminate exterior advertising displays when the vehicle is operating on the alternative power source or in a fuel-efficient mode.

  • Patent number: 6078665
    Abstract: A device and method is provided using a split processor based architecture to provide physical security of information by implementing a required protocol before releasing information. The information is used as a key to a cryptographic algorithm. A chaotic cryptographic algorithm is also provided including a key space employing six parameters of a Lorentzian system of equations.

  • Patent number: 5857025
    Abstract: A device and method is provided using a split processor based architecture to provide physical security of critical information by implementing a required protocol before releasing critical information. The critical information is used as a key to a cryptographic algorithm. A chaotic cryptographic algorithm is also provided including a defined key space employing six parameters of a Lorenzian system of equations.

  • Patent number: 5377269
    Abstract: A system for controlling access to a computer. Memory-resident software logic cooperates with a remote electronic key device coupled to the computer's processor, through the printer port, to disable the computer unless an authorized key is inserted in the key device. The logic is executed in the processor responsive to the computer's system timer interrupt for continuous monitoring capability. Until a user inserts an authorized key, or upon removal of the key, the logic suspends operation of any application programs, the monitor is blanked and the mouse, keyboard and floppy disk drive are disabled. A record is stored in memory of authorized users and user audit information. Utility menu options are used to add or delete user keys, display access and usage records and to customize the number and selection of I/O devices to be disabled by the system.

  • Patent number: 4955038
    Abstract: A RF receiver with extremely low standby power consumption. To minimize power consumption during standby, the analog input from the antenna circuit (including tank resonator) is connected directly to the inputs of a comparator.Preferably two comparators are used, each connected to a separate antenna. Thus, a signal loss due to antenna nulls will be minimized.Preferably a following stage decodes a pulse-width-modulated (or burst-length-modulated) signal. If the length of pulses substantially exceeds the expected maximum, the following stage provides a control signal to reduce the gain of the input comparators.
