  • Patent number: 6808140
    Abstract: A VTOL vehicle including a fuselage with two foldable wings, two tiltable nacelles attached to the wings, a vertical stabilizer, a horizontal stabilizer, and two auxiliary thrusters. Each nacelle contains a system of vanes located at the rear opening thereof, and actuators are provided for extending and retracting the vanes in conjunction with nacelle tilting mechanisms to deflect the airflow over a predetermined range of angles from the horizontal. Each nacelle also contains two rotary engines, each of which directly drives a fan. The fans face each other and operate in counter-rotating directions at the same rotational speed. An alternative embodiment includes two additional nacelles attached to the fuselage instead of having the auxiliary thrusters. A redundant computerized flight control system maintains stability of the vehicle as it transitions from one flight mode to another.

  • Patent number: 6711624
    Abstract: A data exchange process is implemented by a computer system coupled for communication with a remote index server via a network. The process provides for transfer of a data block from a source host having an internal source data format, to a destination host having an internal destination data format different from the source data format. The process includes the steps of: determining characteristics of the source data format by comparing the source data format to sets of data format characteristics stored in a memory storage space of the computer system to determine if a predetermined relationship exists between the characteristics of the source data format and a particular one of the sets, and if so, a source driver associated with the particular set is accessed from memory of the computer system, the source driver being capable of extracting a data block from the source host and converting the format of the data block to an intermediate data format.

  • Patent number: 6695654
    Abstract: The invention discloses a retractable rudder device attached to the water jet nozzle of a watercraft. In a non-deployed condition, the rudders are latched in position and completely out of the water stream underneath the craft. When deployed, two rudders aligned with the axis of the steering nozzle, are rotated into position via springs and cables. The rudders pivot independently of each other, and will retract if contact with an underwater object is made or the craft is beached. A cable system connected to a control unit lowers the rudders into the deploy position. The cable system is actuated by a hydraulic cylinder using fluid pressure from the jet pump. The deployment rate can be varied by altering the fluid pressure in the hydraulic cylinder, and is a function of boat speed. Deployment of the retractable rudder system is determined by an electronic control system.

  • Patent number: 6651511
    Abstract: Apparatus and method for measuring mass flow rate of fluid materials including a rotationally oscillating probe attached to a support at one of its ends and adapted for extension into a flow stream. The fluid flowing thereabout interacts with the probe to produce an oscillatory Magnus lift force that is distributed along the portion of the probe exposed to the fluid stream and is directed substantially perpendicular to both the direction of fluid flow and to the rotational axis of the probe. The amplitude of the rotational oscillation is related to the fluid's mass flow rate and is determined using motion-responsive sensors. Electronic circuitry and processor means convert electrical signals generated by the sensors to develop an output signal proportional to mass flow rate. The probe assembly can be implemented in various forms including “concentric tuning fork”, “linear rotational tuning fork” and “parallel rotational tuning fork” arrangements.

  • Patent number: 6546163
    Abstract: A planar waveguide integrated optic switch suitable for use in optical cross-connect applications. A narrow trench in the planar waveguide core layer is filled with a liquid crystal material possessing positive birefringence. When held at a temperature a few degrees above the clearing point, the liquids crystal's isotropic refractive index is matched to that of the core layer allowing nearly complete optical transmission through the switch. When held at a temperature a few degrees below the clearing point, the liquid crystal's ordinary refractive index is lower than that of the core layer and both polarizations of the incident optical radiation are totally reflected from the trench. When coupled with planar waveguide beam expanding and refocusing elements, arrays of the switches can be used to form an optical cross-connect capable of fully interconnecting linear arrays of single- or multi-mode optical fibers with very low optical loss.

  • Patent number: 6507207
    Abstract: An improved contact probe pin for wafer probing apparatus including an elongated metal conductor having a connector (or proximal) end, a center or medial section coated with an elastic material, and a contact pad engaging tip end. At least a portion of the center section of the probe pin is coated with a poorly conductive, but highly elastic material so as to enhance its flex characteristics. The coating may uniformly cover a portion of the center section of the probe pin or it may take on a predetermined pattern or shape. The coating may also unevenly cover a portion of the center section of the probe pin. The coating is selected such that it augments or enhances the resiliency of the pin and causes it to have a predetermined stress-strain profile with vertical (or Z-axis) displacement, and thus enables it to have predetermined probe pin tip contact force characteristics.

  • Patent number: 6488824
    Abstract: A sputtering apparatus and method for high rate deposition of electrically insulating and semiconducting coatings with substantially uniform stoichiometry. At least one set of vertically mounted, dual and triple rotatable cylindrical (or planar) magnetrons with associated vacuum pumps, form semi-isolated sputtering modules. The sputtering modules can be independently controlled for the sequential deposition of layers of similar or different materials. Constant voltage operation of AC power with an optional reactive gas flow feedback loop maintains constant coating stoichiometry during small changes in pumping speed caused by substrate motion. The coating method is extremely stable over long periods (days) of operation, with the film stoichiometry being selectable by the voltage control point.

  • Patent number: 6480885
    Abstract: A method for enabling users to exchange group electronic mail by establishing individual profiles and criteria, for determining personalized subsets within a group. Users establish subscriptions to an electronic mailing list by specifying user profile data and acceptance criteria data to screen other users. When a user subscribes, a web server establishes and stores an individualized recipient list including each matching subscriber and their degree of one-way or mutual match with the user. When the user then sends a message to the mailing list, an email server retrieves 100% her matches and then optionally filters her recipient list down to a message distribution list using each recipient's message criteria. The message is then distributed to matching users. Additionally, email archives and information contributions from users are stored in a database. A web server creates an individualized set of web pages for a user from the database, containing contributions only from users in his recipient list.

  • Patent number: 6456106
    Abstract: A method and circuit for detecting primary switch (12) status in isolated DC/DC converters by observing the falling speed of the voltage level at the sensing point (node Z) is disclosed. It is noted that high impedance oscillation has a relatively slow falling or rising time when compared to a valid signal. By observing the falling or rising time of a given signal during the appropriate time period, a determination can be made to differentiate a valid signal and an oscillating signal. More specifically, two reference voltages (A & B) are provided to compare against node Z voltage to generate a sense pulse. A reference pulse having a predefined duration is compared to the sense pulse. If the duration of the sense pulse is greater than the duration of the reference pulse, a latch is used to generate a low output signal. If the duration of the sense pulse is less than the duration of the reference pulse, a high output signal is generated.
