  • Patent number: 6208248
    Abstract: An Ultra Wideband (UWB) short-range radar system is used for the detection of targets in clutter. Examples of targets on the ground include human walkers, crawlers and runners, and vehicles. The UWB sensor can also be used to detect small approaching boats in different levels of sea clutter or airborne targets like hang gliders. One of the primary differences between this device and other UWB radar sensors is the manner in which the bias on the threshold detector is set as well as the logic circuitry used to find targets in clutter while maintaining a low false alarm rate. The processing is designed to detect targets in varying degrees of clutter automatically. There may be no front panel controls other than an ON-OFF switch. The system is lightweight, low-cost, and can be easily installed in minutes.

  • Patent number: 5974407
    Abstract: The invention is directed to a computer implemented system and apparatus for construction of a Hierarchical Database Management System (HDBMS) using a commercially available Relational Database Management System (RDBMS) as the implementing apparatus. The invention uses one or more RDBMS tables to store rows of a hierarchical database implemented by the HDBMS. Composite keys, unique over all the tables, are used to maintain hierarchical families and maintain the hierarchical parent/child relationships within families. Root conditions and child conditions may be used to determine which tables may be used for adding root row starting a new family, and which tables may be used for adding a child row of a selected parent row. SQL select queries present hierarchical views of the hierarchical database. SQL action queries are used to perform the database functions of insert root, insert child, update row, and delete row and its descendents.

  • Patent number: 5640138
    Abstract: A safety device is used to protect golfers located in blind areas of a golf course from balls being driven, for example, off the tee. The safety device is manually activated by a push-button switch once the golfers enter the blind area. The switch initiates a low current drain, high-intensity, strobe light blinking at a 1 Hz rate that is visible from both the tee and blind areas even in bright sunshine. An electronic timer deactivates the strobe after N minutes. A wireless transmitter link located outside the blind area can be used to recycle the timer prior to the elapsed time (minutes) for those golfers who play more quickly.

  • Patent number: 5455593
    Abstract: An Ultra-Wideband (UWB) transmitter array consists of N individual transmitters coupled to a reference cw oscillator. Each of the N transmitters generates a waveform consisting of a number of cycles of a nominal carrier frequency of f.sub.0. The duration of the amplitude spectrum of the envelope of each signal is T. The transmitters are arranged in close proximity to form a multipole moment and are precisely synchronized to each other and delayed appropriately so that the resulting amplitude spectrum of the envelope of the transmitter array is due to a pulse duration of NT seconds. This reduces the overall signal bandwidth by a factor of N, at the same time increasing the radiated energy by a factor of N.

  • Patent number: 5337054
    Abstract: A four-terminal network in tandem with a tunnel diode (TD) threshold receiver currently used in radar or communications improves its sensitivity. Previous inventors have shown that the temperature and sensitivity properties of a conventional TD threshold device used for detecting very short duration bursts of microwave energy would be enhanced by appropriately biasing the TD by a current derived from the thermal noise; the current sets the TD operating point. The magnitude of the current is determined by a constant false alarm rate (CFAR) feedback loop. The subject invention recognizes that a TD changes states (i.e., a detection event) when the area under the current vs. time curve or the charge passing through the device exceeds a prescribed number of picocoulombs. To maximize the charge and improve detection, a form of superheterodyne conversion is introduced to convert the oscillatory short pulse microwave signal received by an antenna to a monopolar baseband signal.

  • Patent number: 5257365
    Abstract: The subject invention is directed to a database system for organizing large amounts of data to be accessed by a digital computer. More particularly, a free form type database, in the form of a summarized, multikey tree, is built from files stored on the computer. After a building operation, the user obtains specified information by using the summarized database. Information in the files is divided into three categories; that is, a dimension field which comprises data to be organized, a summary field which comprises a numeric quantity on which calculations can be performed, and a non-summary field which comprises other information associated with an input record. The internal nodes of the tree summarize and organize sets of input records. Methods are provided for reducing the amount of storage space used by cutting off the tree when the size of sets go below a given threshold, and sharing parts of the tree so that each record does not appear n! times in the database.

  • Patent number: 5220606
    Abstract: I present a cryptographic communications system and method. The system includes a communications channel that is coupled to an encryption device and to a decryption device. A sender's plaintext message is encoded into ciphertext at the encryption device by first transforming the plaintext into a number sequence M. The encryption device couples the sender's signature S with an encoding key K to convert M into a ciphertext C. Ciphertext C is then transmitted over the communications channel to the intended receiver of the message.The receiver's decryption device acquires the ciphertext C. The decryption device takes the sender's signature S and the encoding key K and develops an inverted form of S which is the sequence T. The device uses T and K to decode C and obtain the digital message M. Sequence M is then converted to the original plaintext message.The sender's signature S is known at the encryption and decryption devices. S is kept secret from unauthorized persons.

  • Patent number: 5216695
    Abstract: This invention describes a high voltage, very short pulse, microwave radiating source using low-cost components, and capable of operating at high pulse repetition frequencies (prf). The source is activated by an ordinary video trigger commensurate with driving TTL logic. A trigger will cause a chain of N (where N may be 12 or greater) avalanche transistors connected in a Marx generator configuration to threshold resulting in a 1,200 volt or greater baseband pulse having a rise time of less than 100 ps and a duration of about 3 ns driving the input port of a dipole antenna. The dipole is excited by a balun. This invention achieves very short pulse duration broadband microwave radiation at pulse repetition frequencies as high as 30 kHz or greater.

  • Patent number: 5148530
    Abstract: In a data processing system using a virtual memory adressing scheme, certain software instructions call for the virtual address to be stored in a base register. The virtual address stored in the base register is incremented or decremented during the read out cycle of the previous operand to address the next operand. If the operand is not in physical memory, then the contents of the base register is restored to its original value.

  • Patent number: 5142579
    Abstract: A public key cryptographic system and method includes an insecure communications channel connecting at least two communicating complexes, a sender and a receiver. The sender possesses an encoding device and the receiver possesses a decoding device. The sender uses a public key that may be known by an unauthorized receiver and that is generated by random processes known only to the receiver to encrypt a plain text destined for the receiver. The transformation of plain text to encrypted text using the public key is easily performed, but the inversion of that transformation using only the public key information and the knowledge of the operations of encryption and decryption is extremely difficult and computationally infeasible. The receiver uses the knowledge of the randomly generated transformation set components (the private key) to easily and incrementally invert the encrypted text and recover the plain text.

  • Patent number: 5134706
    Abstract: A bus interface interrupt arrangement is disclosed which provides separate interrupt controllers for each bus in a multibus computer system where the processor is connected to one of the busses. Interrupt requests decided on each of the busses other than a primary bus to which the processor is connected are input along with interrupts from circuits connected to the primary bus to the interrupt controller for the primary bus. The interrupt request decided by the interrupt controller for the primary bus is connected to an interrupt input of the processor. All interrupt controllers are connected to the primary bus and may be accessed by the processor. When an interrupt from one of the busses other than the primary bus is chosen by the processor, the processor must read the interrupt controllers to determine first what bus, and then identify the circuit that generated the interrupt that has been acknowledged.
