Abstract: Methods and apparatus for using multi-component geophones and/or multi-component geophone arrays to measure flow-induced acoustic energy produced in wellbores are provided. With the use of the multi-component geophones, the measured acoustic energy may be resolved into its directional components. The computed directional energy components may be mathematically compared to numerically highlight ambient flow conditions (e.g., leaks in casing or other conduit, points of fluid entry/exit/restrictions between the casing and the formation). The use of an array of multi-component geophones allows for the use of geophone move-out curves to further identify acoustic energy source locations.

Abstract: The invention is an apparatus and technique for tuning the cross coupling of resonators in a dielectric resonator circuit. A cross coupling element such as a coaxial cable having a first end positioned adjacent a first resonator in the circuit and a second end position adjacent a second resonator is supported on the housing of the circuit intermediate its first and second ends. At least one end of the cross coupling element is in contact with a cross coupling tuning element that extends through an external wall of the housing so that it can be manipulated from outside of the housing to move the corresponding end of the cross coupling element relative to the adjacent resonator inside the housing without opening the housing.

Abstract: An attachment assembly provides quick attachment of an automotive antenna unit or other object to the exterior of a vehicle. A single worker is able to install the antenna unit or other object with one downward push from the exterior without the need for tools. The attachment assembly also includes an anti-rotation feature to prevent rotation. The attachment assembly can only be removed from the interior, rendering the attachment assembly tamper resistant from the exterior. The attachment assembly can also be mounted on vehicles with various panel thicknesses.

Abstract: A unique solar shield and a solar-ray shielding method are disclosed. The solar shield of the present invention is divided essentially into two parts—a wrapping member and a mounting plate. The wrapping member wraps around an electronic device. The mounting plate holds the wrapping member around the electronic device. The electronic device is fixedly attached to the mounting plate using known fasteners such as bolts. The solar shield shields the electronic device from solar rays and prevents unwanted heat absorption due to the solar rays.

Abstract: A Balun assembly has a signal conductor (2) on the balanced side of a Balun, the signal conductor (2) being joined to a microstrip RF launch area 7 on a circuit board 6, the signal conductor (2) having a bend of axial orientation for lower cost, reliability, avoiding contact with a ground circuit path (9), being more suited for higher volume manufacturing, that distributes thermal expansion and contraction thereof substantially throughout to lessen stress at a junction of the signal conductor (2) and the RF launch area (7), and the signal conductor (2) being of minimum length and of smooth and even curvature to lessen impedance mismatch at the junction.
