Abstract: A robot arm comprising: a first link connected to a second link by a joint, the joint permitting the second link to move relative to the first link; a motor for driving the joint; and a controller for controlling the motor. The controller is configured to electrically brake the motor in response to detection of a fault in the robot arm by applying a braking current to the motor so as to maintain the position of the joint against gravity. The controller only performs this electrical braking if the joint is in a configuration in which the robot arm will droop under gravity if the joint is not actively driven.

Abstract: A system for the enhancement of sonar data is provided comprising one or more processors, a memory, and one or more sonar transducer assemblies configured to provide sonar data. The memory includes computer program code configured to, when executed, cause the processor(s) to receive the sonar data, with the sonar data providing information representative of an underwater environment around a watercraft. The computer program code is also configured to, when executed, cause the processor(s) to perform adaptive contrast image processing to adjust a brightness level or color of the sonar data at one or more locations and to form adjusted sonar data. Adaptive contrast image processing considers a distance of a location from a sonar transducer assembly of the one or more sonar transducer assemblies, a brightness level, color, water clarity, or depth associated with a location, an object type, or an orientation or surface properties of the object.

Abstract: Changing a method to control engine operation is disclosed. The invention/system relates to an apparatus of an engine. We'll provide a similar process for how a mechanical system runs. Using today's method, engines have dedicated operation to use fuel constantly. An operating system using the present mechanical method has problems. Engines waste most of the fuel. The present method has an explosion (pulse) when an engine rotates 90°. It's about 3? apart along the ground in high gear. Engines fire before top dead center (TDC) but by the time the crank rotates to 90° after TDC pressure reduces to about 300 psi. Pressure drops ½ (600 drops to 300 psi in labs) after explosions. Rapid cooling from 900° F. depletes pressure. Lab data shows near 300 psi at 90° after TDC. Videos show a decrease in 100ths of a sec. An electronic system makes dynamic operation changes.

Abstract: The present disclosure is directed to turbine engines and systems for active stability control of rotating compression systems utilizing an electric machine operatively coupled thereto. In one exemplary aspect, an electric machine operatively coupled with a compression system, e.g., via a shaft system, is controlled to provide shaft damping for instability fluctuations of the pressurized fluid stream within the compression system. Based on control data indicative of a system state of the compression system, a control parameter of the electric machine is adjusted to control or change an output of the shaft system. Adjusting the shaft system output by adjusting one or more control parameters of the electric machine allows the compression system to dampen instability fluctuations of the fluid stream within the compression system. A method for active stability control of a compression system operatively coupled with an electric machine via a shaft system is also provided.
