  • Patent number: 11901759
    Abstract: A method of developing a charging profile for charging a lithium-ion battery. A first phase of charging is at a constant current level, with the constant current level selected on the basis of battery resistance during charging and differential voltage (dV/dQ) analysis. A switch point is selected on the basis of a state of charge (SOC) of the battery when dV/DQ values increase. Next is an increasing voltage charging phase, with the voltage rate selected on the basis of charge acceptance and charge time.

  • Publication number: 20240011852
    Abstract: A tribometer and technique for determining torque at a physical interface of multiple rotating components. The tool and technique include aligning components about a rotational axis for independent rotation of each component. The components are in physical interface during the rotating with a resultant frictional torque. The torque may be measured by one or more torque meters during the rotating. This measured torque may be compared against an estimated torque for tool accuracy. Further, parameters such as load, temperature, component material, rotating rpm differentials and others may be varied to determine effect on measured frictional torque.

  • Patent number: 11821682
    Abstract: The systems and methods described herein integrate a supercritical fluid power generation system with a LNG production/NGL separation system. A heat exchanger thermally couples the supercritical fluid power generation system with the LNG production/NGL separation system. A relatively cool heat transfer medium, such as carbon dioxide, passes through the heat exchanger and cools a first portion of extracted natural gas. The relatively warm heat transfer medium returns to the supercritical fluid power generation system where a compressor and a thermal input device, such as a combustor, are used to increase the pressure and temperature of the heat transfer medium above its critical point to provide a supercritical heat transfer medium. A second portion of the extracted natural gas may be used as fuel for the thermal input device.

  • Patent number: 11807021
    Abstract: A method of using an automated system to position a fabric piece. A pattern is printed onto a fabric piece with fluorescent ink, and detected with a fluorescence-detecting camera, such as a UV camera. The detected pattern is stored in a controller as a pattern signature and compared to a stored target pattern. The results of the comparing step are used to generate control signals for the automated system to move the piece into the position of the target pattern.

  • Patent number: 11799414
    Abstract: A passively deployable solar panel array. A truss backing is attached to the back of the solar panels, and has top segments, bottom segments, and hinge linkages that form a series of moveable parallelograms operable to fold and unfold. The truss backing further has springs and trusses, with at least one spring and one truss associated with each of the parallelograms. The springs are operable to deploy the solar panels from a folded position to a deployed position. Each truss is operable to become in tension diagonally across its associated parallelogram once the solar panels are deployed into a final position.

  • Patent number: 11788521
    Abstract: A compressor system for receiving a gas fluid and discharging the gas fluid at a higher pressure. The system comprises at least one compressor and at least one piston intensifier associated with each compressor. Each piston intensifier has a double-acting piston, with one piston head reciprocating in an actuation cavity and the other piston head reciprocating in a high pressure cavity. The compressor delivers its output flow to both cavities of the piston intensifier, alternating between below and above their piston heads, to provide both a working (actuation) fluid and a fluid to be compressed and discharged. A return flow from the actuation cavity back to the compressor also alternates to recycle the working fluid.

  • Patent number: 11761883
    Abstract: A fumed silica monolithic integrating cavity device. The device is configured to facilitate optical measurements taken from a sample positioned within a cavity of the device. The cavity is defined by a fumed silica monolith with the added feature of a fused quartz lining on the surface of the monolith. This provides an intermediate surface that allows for cleaning and reuse of the highly effective diffuse light scattering fumed silica monolith. Furthermore, the lining may be placed under pressure or vacuum to structurally enhance mechanical integrity of the underlying monolith. Thus, continued or reliably repeated use of the device may be appreciated as well as use in more industrial environments that are prone to vibration.

  • Patent number: 11739681
    Abstract: A far square or diamond architecture engine with tumble flow to support spark-ignited fuel usage. The engine may be provided in a configuration generally suited for swirl flow, compression combustion fuel usage. However, the introduction of a unique, replaceable valve head assembly may be utilized to induce tumble flow within a combustion chamber of the engine. Thus, spark-ignited fuel may be utilized without requiring vast overhaul of the engine to accommodate such fuels. Notably, with the addition of such an assembly, diesel fuel may be replaced with natural gas on large scale equipment without the requirement of impractically burdensome or expensive measures.

  • Patent number: 11721437
    Abstract: A method of generating a digital twin and of using the digital twin to predict activity of an animate subject. The digital twin is generated from at least system model data and movement data. The digital twin can be activated to simulate a specified activity that the subject is performing or will perform. If desired, the subject can be instructed to perform the same activity while wearing at least one wearable sensor, which is applied to the digital twin. Using artificial intelligence techniques, the activity simulation predicts one or more physical outcomes from the activity.

  • Publication number: 20230236114
    Abstract: A seamless fumed silica monolithic integrating cavity device tailored to analyzing a flowed sample. The device is configured to facilitate optical measurements taken from a sample flowed through a cavity of the device. The cavity is defined by a fumed silica monolith with the added feature of a fused quartz lining on the surface of the monolith. This provides an intermediate surface that allows for cleaning and reuse of the highly effective diffuse light scattering fumed silica monolith. The lining may be placed under pressure or vacuum to structurally enhance mechanical integrity of the underlying monolith. Thus, continued or reliably repeated use of the device may be appreciated as well as use in more industrial environments that are prone to vibration. Additionally, while well suited for flow-based sample analysis, a valve of the cavity may be utilized for holding a sample in a temporarily static state for measurement.
