Abstract: An example immersive audio signal processing system and a computer-implemented method for generating a target arena environment audio stream are provided. The example immersive audio signal processing system includes a plurality of multi-lobe digital sound wave capture devices positioned within the arena environment. The plurality of multi-lobe digital sound wave capture devices is configured to direct first beamformed lobes to a playing region of the arena environment, second beamformed lobes to a spectator region of the arena environment, and third beamformed lobes to a noise source region of the arena environment. A digital signal processor is configured to isolate noise audio components originating from at least the spectator region or the noise source region from the audio signal stream and generate a target arena environment audio stream.

Abstract: The present disclosure generally relates to a bearing hub assembly of a rail guide wheel apparatus for a rail vehicle. The bearing hub assembly may couple rail wheels to the rail guide wheel apparatus. The rail guide wheel apparatus may be included on a Hi-Rail vehicle or any other vehicle configured to travel along railroad tracks. The bearing hub assembly includes a sensor that is integrally mounted within the bearing hub assembly. The sensor collects information associated with rotation of the rail wheels. Information collected by the sensor may be used to determine a speed, direction, location, and/or distance traveled of the rail vehicle.

Abstract: In a particular implementation, a vehicle detector configured to detect a train entering a work zone includes a detector portion including one or more motion detectors. The one or more motion detectors are configured to detect a vehicle entering a work zone. The vehicle detector also includes a vertical member coupled to the detector portion. The vehicle detector further includes a stabilizing structure including one or more components configured to stabilize the vertical member. The one or more components define a circumference around the vertical member.

Abstract: A phantom for use in an MRI or MRS system includes an array of subresolvable compartments that are each connected to receive fluid from one of a plurality of fluid reservoirs. The array of compartments is divided into sub-arrays which differ from each other by the mix of compartments in each sub-array receiving fluids from the different reservoirs. Studies can be performed with the phantom by filling the compartments with selected fluids from the reservoirs, disconnecting the reservoirs and placing the phantom in the system bore. The phantom can be reused in other studies by replacing the fluids with different fluids.

Abstract: The present invention relates to an electronic controller and a computer-implemented method for a water storage system. The water storage system (10) has a storage tank (12) connected to a main energy source (24) and a main water source (14). The electronic controller (22) is provided with at least one sensor (32) to generate a sensor signal representing the state of the water in the storage tank (12). There is also an input device (38) for a user to input a command signal into the controller (22). A processor in the controller (22) receives the sensor signal, command signal, and source information relating to at least one of the main energy source (24) and main water source (14).

Abstract: The present invention relates to a centrifugal pump and a method of varying the properties of a centrifugal pump. The centrifugal pump has a pump housing, which in the preferred form comprises a front casing 22 and a back casing 24. The pump also includes an impeller 26. The present invention provides the centrifugal pump with one or more grooves 29 in the housing adjacent the impeller 26. The one or more grooves are adapted to removably receive a cutwater 28.

Abstract: A method for magnetic resonance imaging includes performing a preparatory stage of a MR pulse sequence with an MRI system in which a non-selective RF preparatory pulse is used having a bandwidth such that any spin species having corresponding Larmor frequencies within that bandwidth are affected and the bandwidth is centered at a selected frequency which is offset from a nominal Larmor frequency of the desired spin species being imaged. A time period (TI) elapses during which longitudinal spin magnetization recovers; and then an imaging stage is performed in which an RF excitation pulse is generated to produce transverse spin magnetization of the desired spin species, and in which a set of NMR signals are acquired. An image is reconstructed using the acquired set of NMR signals, and the reconstructed image has reduced artifacts due to B0 field inhomogeneities caused by magnetic susceptibility effects.

Abstract: The present invention relates to a method and system for correctly installing a flexible liner in a tank for water storage. The present invention in the preferred form relates to the use of a substantially rigid outlet (20) in the flexible liner (12) that is received in a tank aperture (22) when the liner (12) is correctly installed in the tank (14).

Abstract: An on-car disc brake lathe system for resurfacing a brake disc of a vehicle brake assembly includes a lathe body with a driving motor, a cutting head operably attached to the lathe body, and a drive shaft. The system also includes an alignment system having an electronic controller, input and output adaptors configured to rotate with the drive shaft, one or more adjustment discs, and an adjustment mechanism. The adjustment disc is positioned between the input adaptor and the output adaptor, and an axial alignment of the input adaptor relative to the output adaptor may be varied based on a rotational orientation of the adjustment disc. The adjustment mechanism is configured to change the rotational orientation of the adjustment disc in response to commands from the electronic controller.

Abstract: An apparatus and method for automatically compensating for the lateral runout between an on-car lathe apparatus and a vehicle hub axis including one or more stop discs that rotate with the drive shaft of the lathe and that can be selectively stopped from rotating with the shaft by a stop mechanism. In response to such stopping, one or more adjustment discs are caused to rotate in order to adjust the relative position of the axis of the lathe with respect to the axis of the disc brake assembly. In this manner, the system compensates for and corrects lateral runout that exists between two concentrically attached rotating shafts.
