  • Patent number: 7319212
    Abstract: A non-invasive microwave analysis system determines scattered phase and/or amplitude data for a liquid in a container. A tank holds coupling liquid; the system includes a membrane for separating the liquid container from the coupling liquid. A transmitter antenna situated within the coupling liquid transmits microwaves. One or more receiver antennas within the coupling liquid convert microwave radiation that scatters from the liquid in the container into microwave electronic signals. Electronics process the microwave electronic signals to determine scattered phase and/or amplitude values of the microwave radiation.

  • Patent number: 7318459
    Abstract: A system for pneumatically conveying flexible fabric items such as uniforms and table linens has a pair of side outlets at each discharge location to enhance the discharge capacity. Each side outlet is provided with a gate to open and close the outlet. A hopper having a chute receives the items discharged through the corresponding outlet. A sling cart or other bin underlies each chute. When a cart is full, hopper doors can be closed to allow the hopper to serve as a temporary holding bin while the conveying system continues to operate without interruption as the full cart is moved and replaced by an empty cart.

  • Patent number: 7302839
    Abstract: Disclosed is a method of and system for gathering off-body pressure signature data from a scaled model in a wind tunnel. The data is gathered using a probe having multiple longitudinally disposed static pressure ports. Because of the number of ports and their spacing, the probe is able to remain stationary in the tunnel for the entire range of Mach numbers and model positions to be tested. Thus, tunnel flow characteristics can be easily and effectively removed. The system also has an automated model positioning system which enables settings at different pitch, yaw, and roll angles. This enables the user to locate the model so that it can be traversed at a fixed distance above the probe while maintaining the desired angular orientation of the model. By repeatedly traversing the model at different angular orientations, a detailed and accurate off-body pressure distribution can be obtained. The wind tunnel test technique captures full off-body pressure signatures in a complete 360 degree azimuthal range.

  • Patent number: 7297931
    Abstract: An apparatus is provided to effectively reduce the non-active detection gap between sensor elements of an optical sensor. Reducing the non-active gap can subsequently reduce the time delay between sensor elements, mitigating the image degrading effects of a composite element time delay. While applicable to use with a wide range of optical sensors, the invention may be used for detecting aspects of a variable-rate dynamic colorful object using a matrix sensor or a tri-linear color CCD sensor. In one variation, optical fibers extend from a first fiber optic faceplate to a second fiber optic faceplate. The optical fibers can be oriented toward or directly mounted to the sensor elements. A spacer may be used to separate the optical fibers for alignment with the sensor elements and the other end of the optical fibers are attached to each other.

  • Patent number: 7296163
    Abstract: The invention provides a method for encrypting a program for execution on a remote host computer on a network, such that correct execution by the remote host computer is ensured, and such that the remote host computer remains unaware of the computations or data associated with execution. Results from the computations at the remote host computer are transmitted to a control computer, on the network, which decodes the results to useful data representative as output from the program. In a first step of the method, the program is encoded as a unitary matrix multiplication, Uij, of i dimensions by j dimensions. Un is the set of unitary matrices of size n, forms a non-commutative group under matrix multiplication, and has a unique group-invariant Haar measure probability distribution; Uij is thus an element of Un. In a second step, an input data string to the program is encoded as a vector bj of n dimensions. The first and second steps can be performed in either order.

  • Patent number: 7270088
    Abstract: A system for storage and delivery of a fuel additive to a fuel tank includes a reservoir in fluidic communication with a volumetric pump, through a tubular member such as a steel-braided hose. The pump is in further fluidic communication with the fuel return line of a vehicle, via another tubular member, such as a steel-braided hose. Valves disposed along the fluidic pathway prevent backflow of additive. The pump is electrically connected to and actuated by a timer, the timer calibrated to a rate of the pump to provide a predetermined amount of fuel additive necessary to treat an amount of fuel added to the fuel tank of the vehicle. A user interface with user-selectable, volumetric settings and control switches is electrically connected to the timer. A related method of adding a fuel additive to the fuel tank of a vehicle is also disclosed.
