Abstract: A radio resource management (RRM) system and method manages radio resources in a wireless network of radio access points (APs). In some embodiments, the channel and/or frequency of radios of the APs are managed based on a prioritization scheme of the radios. In some embodiments, the transmit powers of the radios are managed based on the prioritization scheme. The priorities of the radios is partially based on the priorities of clients connected to the radios. In some embodiments, the RRM system is a centralized controller system. In some embodiments, the RRM system forms a hierarchical network of child and parent nodes. The parent nodes are configured to manage the radios associated with the parent and its child nodes. The parent node with the smallest number of child nodes, which are associated with the selected radio and its neighboring radios, is managing these radios.

Abstract: A system and method for identifying and quantifying targets within a liquid medium. A raw sidescan sonar image is collected. A region of interest is separated from the image. An image transformation is performed using an extraction algorithm. Salient image characteristics are calculated. Spurious pixels are removed from the image to obtain an extracted region of interest. Particle analysis is performed on the extracted region of interest to generate a feature vector which is presented to a neural network for classification.

Abstract: A lift truck having an acceleration sensor and a feedback control system for automatically adjusting the tilt angle of the load supporting surface relative to the lift truck during lift truck operation. The control system maintains the load supporting surface substantially perpendicular to the direction of the resultant of the gravitational force vector and the travel acceleration force vector. The sensor is mounted to the mast for sensing the direction of the resultant vector and is connected as the feedback element of the control system. A controller stores a reference input comprising a stored value of angular direction representing the angular direction of the resultant vector when the lift truck is at rest and the cargo support fork is horizontal. The deviation or error of the control system is the difference between the stored vector direction and the sensed vector direction of the resultant of the two accelerations.

Abstract: A throttle valve apparatus for controlling fluid flow is provided, which includes a first hollow body portion, a second hollow body portion, and an internal duct. The first hollow body portion, second hollow body portion, and the internal duct, each extends along a longitudinal axis of the apparatus. The duct is formed from a pliable membrane. The duct is attached to the first body portion at a first duct location. The duct is also attached to the second body portion at a second duct location. The first body portion and the first duct location are adapted to pivot about the longitudinal axis relative to the second body portion and the second duct location for twisting and untwisting the duct. Preferably, yet optionally, rods are in contact with the duct and extend generally along the longitudinal axis for supporting the duct.

Abstract: An interconnect via structure according to the present invention can be used to support high frequency broadband signal transmission. The interconnect vias progressively increase in size and pitch from the signal source layer of the package substrate to the terminal pad layer of the package substrate. Each interconnect via includes a plurality of conductive sections formed at different substrate layers. At each substrate layer, the size and pitch of the vias result in a specified impedance. In a practical embodiment, the via impedance at each substrate layer is constant (e.g., 50 ohms). The interconnect structure can maintain a constant impedance while transitioning from a relatively narrow pitch at the signal source layer to a relatively wide pitch at the terminal layer, which may correspond to the pitch of the package substrate solder balls.

Abstract: An electronic package, such as a ball grid array (“BGA”) package, includes a high speed signal trace formed at a conductive layer and a corresponding reference plane formed at another conductive layer. The reference plane includes a cutout region formed therein; the cutout region is positioned over the signal solder ball to which the high speed signal trace is coupled. The lateral center point of the cutout region is offset relative to the lateral center point of the signal solder ball. The offset configuration reduces the capacitance between the signal solder ball and the reference plane and improves the high frequency transmission characteristics of the electronic package.

Abstract: Environmental monitoring of low concentration of organic compounds in a medium such as ground water or another environmental fluid is effected by using a diffusion cell (112) having a polymeric membrane formed into a helical tube (125) and immersed in the environmental fluid so that organic compounds at ppb and ppt concentrations diffuse into and through the polymeric material. A carrier gas in the polymeric tube acquires a concentration of the organic compounds substantially in equilibrium with the concentration of the organic compounds in the environmental fluid. For the purpose of permitting monitoring with detectors (116) which are not sensitive to extremely low levels of organic compounds, a concentrating device such as a thermal desorption tube (114) can be provided for processing the gas and periodic thermal activation to discharge therefrom organic compounds to be detected at a sensor.
