Abstract: Embodiments relate generally to gimbal bearings for installation of a riser string. Gimbal bearing embodiments comprise a top ring and a bottom ring, with a plurality of high capacity laminate bearings located therebetween, the high capacity laminate bearings comprising at least one of natural rubber and a marker layer. Each high caparity laminate bearing might comprise alternating layers of steel shims and elastomeric elements bonded together via adhesive. Embodiment designs provide for improved gimbal bearing characteristics, which may improve the effective lifespan of such gimbal bearings.

Abstract: A piston assembly for monitoring at least one operating condition of an internal combustion engine and/or piston during use of the piston in the engine, for example during an engine test, is provided. The piston assembly includes an electronic instrumentation unit coupled to the piston for collecting data related to the operating conditions. Instead of a battery or wireless power transfer system, the piston assembly includes a thermoelectric module to provide energy to the electronic instrumentation unit. One side of the thermoelectric module is coupled to an undercrown surface of the piston, which is typically hot due its proximity to the combustion chamber. The opposite side of the thermoelectric module is cooled by a cooling fluid, such as a spray of cooling oil. The temperature flux at the thermoelectric module is converted into electrical energy and used to power the electronic instrumentation unit.

Abstract: A pumping system includes an output conduit associated with an output of a positive displacement pump, a first sensor configured to measure a fluid flow characteristic (FFC) within the output conduit, a second sensor configured to measure a phase of the positive displacement pump, a feedforward active controller configured to receive information related to the FFC, receive information related to the phase of the positive displacement pump, and determine an FFC variability value, and a first fluid flow normalizer (FFN) configured to at least one of add fluid to the output of the positive displacement pump and remove fluid from the output of the positive displacement pump in response to a signal from the feedforward active controller.

Abstract: A separator 252 for immiscible liquids comprises a tank having an inlet, a separation chamber and an outlet chamber 262, with the inlet 12 feeding effluent into the separation chamber 28 at or below a maximum acceptable flow rate. The effluent is separated into a more dense and less dense fractions in the separation chamber 28. The separation chamber 28 is in communication with the outlet chamber 262, where the more dense fraction exits. An outlet 260 for the less dense fraction is in communication with the separation chamber 28 and has a lowermost exit level at which the less dense fluid exits. The more dense fluid cannot rise to the level of the lowermost level, and the height of the less dense fluid is such that it will exit through the outlet as the more dense fluid passes over the weir.

Abstract: A separator for separating oils from waste water and solids. Waste liquids are drained into a baffle tube of the separator so that the oils rise and the waste water and solids migrate to the bottom of the separator. A collection head having a restriction is located at the bottom of the separator and is adapted for suctioning the waste water and the solids therein and carrying the same to a discharge outlet of the separator. Waste liquids drained into the separator provide the hydraulic force to accelerate the waste water and solids into the collection head. Liquids drained into the separator also provide the hydraulic force that allows the oils to be drained from the top of the separator.

Abstract: An internal engine component including a data collector assembly is provided. The data collector assembly includes a sensor for sensing a condition and for generating a signal corresponding to the condition and a digital to analog converter for converting the signal to a digital signal. The data collector assembly also includes a memory for storing data, a clock and a processor. A power source is electrically connected to the sensor, the analog to digital converter, the memory, the clock and the processor. During an engine test, the processor, sensor, digital to analog converter, clock and memory are substantially the only devices that draw electricity from the power source.

Abstract: A hierarchical memory request stream arbitration technique merges coherent memory request streams from multiple memory request sources and arbitrates the merged coherent memory request stream with requests from a non-coherent memory request stream. In at least one embodiment of the invention, a method of generating a merged memory request stream from a plurality of memory request streams includes merging coherent memory requests into a first serial memory request stream. The method includes selecting, by a memory controller circuit, a memory request for placement in the merged memory request stream from at least the first serial memory request stream and a merged non-coherent request stream. The merged non-coherent memory request stream is based on an indicator of a previous memory request selected for placement in the merged memory request stream.

Abstract: A system and method for data allocation in a shared cache memory of a computing system are contemplated. Each cache way of a shared set-associative cache is accessible to multiple sources, such as one or more processor cores, a graphics processing unit (GPU), an input/output (I/O) device, or multiple different software threads. A shared cache controller enables or disables access separately to each of the cache ways based upon the corresponding source of a received memory request. One or more configuration and status registers (CSRs) store encoded values used to alter accessibility to each of the shared cache ways. The control of the accessibility of the shared cache ways via altering stored values in the CSRs may be used to create a pseudo-RAM structure within the shared cache and to progressively reduce the size of the shared cache during a power-down sequence while the shared cache continues operation.

Abstract: A first in, first out (FIFO) queue includes logic to provide detection of operational errors in the FIFO queue. The FIFO queue includes entries to store data written to the FIFO queue and signature bits, each signature bit corresponding to one of the entries. A test pattern and a read signature register includes a number of bits greater than a depth of the FIFO queue. A comparator compares the test pattern to the read signature register and output an error signal indicating whether the test pattern matches the read signature register.

Abstract: A method is disclosed. The method includes obtaining a precursor nanoparticle comprising a base material and a first ligand attached to the base material, and reacting the precursor nanoparticle with a reactant comprising a silicon bond, thereby removing the first ligand.
