Abstract: The present disclosure relates to identifying vehicles using wireless device identifiers. In accordance with aspects of the present disclosure, a system for identifying vehicles in a parking structure includes a camera configured to capture images of an area in the parking structure where the camera captures an image containing one or more vehicle(s), a detector configured to scan for wireless device identifiers in the area, and a processing system including an electronic storage. The processing system is configured to execute instructions to access the image containing the vehicle(s) in the area and access one or more wireless device identifier(s) scanned by the detector in the area, process the image containing the vehicle(s) to extract one or more license plate identifier(s) corresponding to the vehicle(s), and store in the electronic storage at least one record associating the license plate identifier(s) with the wireless device identifier(s).

Abstract: An irrigation system having a pipeline supported by one or more towers includes an improved truss connection system having a means for readily adjusting a crown height of the pipeline. A pair of cooperating members define a joint which selectively couples headed ends of adjacent truss rods together to form a truss rail of a truss system that supports the pipeline. A single fastener may fasten the cooperating members, a strut, and a cross-member together at the joint. A length of the truss rail may be decreased by holding the truss rods closer together. In an aspect, the headed ends of the adjacent truss rods are held closer together by inserting a shim in one of the joints. Decreasing the length of the truss rail increases the deflection of the pipeline and raises the crown height.

Abstract: A greaseless pivot center swivel and bearing device includes an outer housing having a sidewall with top and bottom portions, a top plate coupled with the top portion that includes an opening therein, and a bottom plate coupled with the bottom portion that includes an opening therein. The sidewall cooperates with the top and bottom plates to define an interior volume. A single, unitary bushing member formed of a low-friction material is positioned within the interior volume and includes a surface cylindrically curved about an axis extending between the top and bottom plates of the housing. The cylindrically curved surface cooperates with the openings in the top and bottom plates to define a cylindrical passage through the interior volume sized and shaped for receiving a cylindrical tube that rotates therein, e.g., a tube configured to connect with a water supply column of a mechanized irrigation system.

The first part has a first dimension and the second part has a second dimension that is larger than the first dimension.

Abstract: A system and method for fine needle aspiration includes a plurality of components. A device includes a body unit, a trigger unit, and at least one gear. The body unit is configured to hold a syringe, and the trigger unit is configured to laterally move relative to the body unit in order to extend and retract a plunger within the syringe. The at least one gear is configured to engage the syringe so that lateral movement of the trigger unit causes rotation of the syringe.

Abstract: A technique for enhancing the frequency tuning range for monolithic RF source generation using fully-integrated coupled Voltage-Controlled-Oscillator (VCO) arrays that contain an odd number of VCOs. Fully-monolithic SiGe VCO arrays using on-chip inductor and varactor with on-chip bias current sources have been carefully designed and simulated in IBM 7HP 0.18 ?m BiCMOS technology and taped out for fabrication. The SPICE simulated frequency and phase tuning of the 1-D VCO×5 array is dependent on the edge VCOs termination impedance, the tuning voltages, and the VCO coupling strength. The simulated data suggests that the enhanced tuning range and beam steering can be accomplished using coupled-VCO arrays without needing complex and bulky phase shifters. This design technique imposes no apparent phase noise penalty but can provide simulated RF frequency tuning range of ˜40% and also ˜+/?25° beam steering for active antennas applications.

Abstract: The present invention provides an array of tunable, injection-locking oscillators which are scalable to higher frequencies and measure the entire relevant frequency space simultaneously. The scalable, highly-parallelized, adaptive receiver architecture uses arrays of tunable, injection-locking nonlinear oscillator rings for broad spectrum RF analysis. Three separate and different microelectronic circuit configurations, each having a different type of readout, are described. The embodiments are designed to be incorporated as a subsystem in any type of powered system in which a fast image of the broader spectrum is valuable, when no information about the location of signals in the frequency space is predictable or forthcoming.

Abstract: A system and a method of controlled electrochemical power generation are disclosed. The system includes an electrochemical cell comprising an alkali metal anode, a cathode initially spaced about 10-25 mils from the anode to define a flow channel, an electrolyte comprising an aqueous solution of the hydroxide of the alkali metal and, for example, a separator system adapted for providing a substantially uniform pattern of flow of the electrolyte through the flow channel is utilized in a system and method of controlled power generation. Flow control valves may, for example, be used to control the volumetric flow rate of the electrolyte through the flow channel thereby attaining substantially uniform voltage from the cell.
