Abstract: Provided is a mold cleaning system. When cleaning a mold, the mold cleaning system acquires three-dimensional image data of a molding surface of the mold by a camera and, on the basis of the acquired image data, the mold cleaning system controls the movement of arms using a control device, moves a laser head along the molding surface while irradiating with a laser beam supplied by a laser oscillator and, as a result, removes dirt adhered to the molding surface.

Abstract: Techniques and mechanisms for determining constraints to be imposed on resource utilization by customers of an electric utility. In an embodiment, flexibility metrics are determined each for a different respective customer, the flexibility metrics each indicating a respective difference between a metric of resource utilization, and a respective constraint which is imposed on that resource utilization. The customers are ranked, relative to one another, based on the flexibility metrics, where the ranking is used as a basis for selecting one or more customers to accommodate a change to a power delivery service of the electric utility. In another embodiment, one or more updated utilization constraints are imposed each by a respective customer of one or more selected customers.

Abstract: An electric motor control device that drives a control target load (mechanical load) includes a feedforward controller, a feedback controller, and an adder-subtractor. The feedforward controller receives a position command signal to specify a target position of the control target load and outputs a feedforward position command signal representing a target position of the electric motor, a feedforward speed command signal representing a target speed of the electric motor, and a feedforward torque command signal representing a torque necessary for the electric motor to perform an operation indicated by the target position or the target speed. The feedback controller receives the feedforward position command signal, the feedforward speed command signal, an electric motor position signal representing a position of the electric motor, an electric motor speed signal representing a speed of the electric motor, and outputs a feedback torque command signal representing a torque command to perform feedback control in such a manner that the electric motor position signal and the feedforward position command signal coincide with each other. The adder-subtractor subtracts a load acceleration feedback torque signal obtained by multiplying a load acceleration signal representing acceleration of the control target load by a load acceleration feedback gain from a torque command signal obtained by adding the feedforward torque command signal and the feedback torque command signal, and outputs a result of the subtraction as a torque command correction signal. The feedforward controller generates the feedforward torque command signal so as to previously compensate an effect of the load acceleration feedback torque signal that is subtracted from the torque command signal at a time of an acceleration-deceleration operation.

Abstract: An electric motor control device includes a position controller, a command acceleration calculator, a first subtractor, and a second subtractor. The position controller receives a position command signal specifying a target position of the load and an electric motor position signal representing a position of the electric motor that drives the load, and outputs a torque command signal. The command acceleration calculator receives the position command signal and outputs a command acceleration signal representing acceleration of the position command signal. The first subtractor subtracts the command acceleration signal from a load acceleration signal representing acceleration of the load and outputs a load acceleration correction signal. The second subtractor subtracts from the torque command signal a value obtained by multiplying the load acceleration correction signal by a predetermined weighting coefficient and outputs a torque command correction signal. The torque command correction signal controls a current supplied to a stator winding wire of the electric motor.

Abstract: According to one embodiment, a roll-in cot may include a support frame, a pair of back legs, a pair of front legs, and a cot actuation system. The pair of back legs and the pair of front legs can be slidingly coupled to the support frame. Each of the pair of front legs can include a front wheel and an intermediate load wheel. The intermediate load wheel is offset from the front wheel by a load wheel distance. A front actuator can raise the pair of front legs such that the front wheel and the intermediate load wheel of each of the pair of front legs are aligned along a loading level. The intermediate load wheel of each of the pair of front legs can be offset from the pair of back legs by a loading span. The load wheel distance can be greater than the loading span.

Abstract: A spatially positioned assembly comprising, in preferred embodiments, a fluid inlet in fluid flow communication with a fluid connection adapter. A plurality of boom sections are concatenated in articulated fashion. The plurality is rotatably connected to a turret at a proximal thereof, and is rotatably connected with the fluid connection adapter at a distal end thereof. The fluid connection adapter is disposed for connection to a mating fluid connection housing assembly provided on a wellhead. Independent control of rotation at multiple axes on the spatially positioned assembly allows an operator to establish measured directional bearings at axes, such that sets of measured directional bearings values contribute to defining corresponding spatial positions for the assembly.
