Abstract: In some implementations, a microcontroller may trigger a control loop to read a feedback voltage based on an interrupt that has a periodicity based on a control loop frequency. The microcontroller may calculate a target duty cycle for a first transistor and a second transistor based on the feedback voltage. The target duty cycle may control respective proportions of time that the first transistor and the second transistor spend in an on state. The microcontroller may output, based on the target duty cycle, a first pulse-width modulation (PWM) signal to switch a state of the first transistor and a second PWM signal to switch a state of the second transistor. In some implementations, the first PWM signal and the second PWM signal may be associated with a switching frequency that differs from the control loop frequency.

Abstract: A laser system including a rack, a plurality of laser modules mounted in the rack to drive light through an optical fiber exiting the system, and a power distribution module to distribute electricity through circuit branches coupled to the laser modules is generally presented. In some embodiments, the rack includes a horizontal cross-member with a bottom rack flange extending vertically and defining a bottom of an opening in the rack.

Abstract: An apparatus includes a plurality of laser system modules coupled to a communication bus that includes a module update bus, each laser system module including at least one module update port coupled to the module update bus and at least one micro controller unit (MCU) in communication with the module update port, wherein each laser system module is situated to receive a module update instruction over the module update bus based on a type identifier in a general purpose input/output (GPIO) register of the at least one MCU of the corresponding laser system module that indicates a laser system module type.

Abstract: A collapsible and transportable automated carwash includes a bay with a collapsible frame. The collapsible frame has a plurality of collapsible cross-members. The collapsible cross-members are on the bottom and top of the frame connecting the left side of the collapsible frame to the right side of the collapsible frame. The plurality of collapsible cross-members allows the collapsible frame to collapse and reduce the width of the carwash. Whereby, the collapsible and transportable automated carwash is transportable.

Abstract: A system and method for controlling a wind turbine, including controlling yaw or other parameters. In accordance with an embodiment, each of several basic operating parameters of a wind turbine can be measured to provide turbine operating parameters, including both turbine current parameters and turbine operating extremes. Key operating parameters of the controller itself are also monitored. External/ambient measurement devices or sensors can be used to provide measurements about the environment as a whole, such as external/ambient wind data or other external data. The turbine operating parameters are used by the controller logic to calculate measured energy production. The external/ambient measurements are used by the controller logic to calculate estimated energy production. Comparing these indications provides useful feedback, such as diagnostics and/or efficiency; and/or can be used to control yaw or other parameters in a wind turbine.

Abstract: A flow modulation valve has a slidably translating hollow armature with at least one energizable coil wound around and fixably attached to the hollow armature. The energizable coil or coils are influenced by at least one permanent magnet surrounding the hollow armature and supported by an outer casing. Lorentz forces on the energizable coils which are translated to the hollow armature, increase or decrease the flow area to provide flow throttling action. The extent of hollow armature translation depends on the value of current supplied and the direction of translation depends on the direction of current flow. The compact nature of the flow modulation valve combined with the high forces afforded by the actuator design provide a flow modulation valve which is highly responsive to high-rate input control signals.
