摘要: A method for adjusting a contact position of lift pins in a substrate placement mechanism is provided. The substrate placement mechanism includes a substrate placement table and a substrate lifting mechanism having lift pins and a driving mechanism, wherein the contact position of the lift pins is a height position where tip ends of the lift pins get in contact with the substrate. The method comprises creating torque waveforms, for a plurality of voltages, indicating temporal changes of a torque of the motor while moving the tip ends of the lift; obtaining from the plurality of torque waveforms a contact point when the lift pins get in contact with the substrate and calculating the contact position from the contact point and a speed of the motor; determining whether the contact position is within an appropriate range; and automatically adjusting the contact position when the contact position is not within the appropriate range.

摘要: A highway grade crossing gate mechanism having a smart cam system capable of measuring a parameter of the gate mechanism in real time is provided. The gate mechanism includes a DC motor, a cam system, and a controller. The DC motor is coupled to a main shaft for driving a gate arm between a vertical position and a vertical position. The cam system includes manually adjustable cams coupled to the main shaft that move contacts to open or close at some preset angular rotation in order to set operational features of a crossing gate. An internal sensing device is disposed internal to the cam system measuring a parameter of the gate mechanism in real time. A controller controls the motor and receives and stores the parameter. The parameter may be transmitted to an external network giving accurate feedback of the state of the gate mechanism in real time.

摘要: A methods and system to operate hydraulic fracturing units may include utilizing hydraulic fracturing unit profiles. The system may include hydraulic fracturing units may include various components. The components may include an engine and associated local controller and sensors, a transmission connected to the engine, transmission sensors, and a pump connected to the transmission and powered by the engine via the transmission and associated local controller and sensors. A supervisory controller may control the hydraulic fracturing units. The supervisory controller may be in communication with components of each hydraulic fracturing unit. The supervisory controller may include instructions to, for each hydraulic fracturing units, obtain hydraulic fracturing unit parameters, determine a hydraulic fracturing unit health assessment, and build a hydraulic unit profile including the health assessment and parameters. The supervisory controller may, based on the health assessment, determine the hydraulic fracturing unit's capability to be operated at a maximum power output.

摘要: Systems and methods of wheelchair systems enabling fine manual motion control are disclosed. In one embodiment, a wheelchair system includes a wheelchair. The wheelchair includes one or more wheels, at least one actuator coupled to the one or more wheels, a processing device, and a non-transitory, processor-readable storage medium in communication with the processing device. The non-transitory, processor-readable storage medium includes one or more programming instructions that, when executed, cause the processing device to determine a wheel torque on the one or more wheels, determine a compensation value, and actuate the at least one actuator applying the compensation value to the one or more wheels to remove at least a portion of the wheel torque such that less external force is required to physically move the powered wheelchair than when the compensation value is not applied.
