摘要： A system and method for inducing head motion onto a frame that is secured to the head of a user is provided. A generated counter-rotational reactive force is exerted on the frame to emulate at least one of an apparent movement and an apparent acceleration of an object shown in a visual content portion of presenting media content. One embodiment concurrently operates a first motor to drive a first rotational acceleration of a first rotational acceleration mass based on a determined first acceleration and operates a second motor to drive a second rotational acceleration of a second rotational acceleration mass based on a determined second acceleration, wherein the rotational acceleration of the first rotational acceleration mass and the second rotational acceleration mass cooperatively induces a counter-rotational reactive force on the frame that urges the head of the user.

摘要： An alternative braking apparatus for a vehicle includes a gear type automatic transmission having at least one clutch and at least one brake for changing the meshing state of gears, and a control unit configured to switch the shift stage of the automatic transmission by controlling the clutch and the brake. The control unit is configured to perform alternative braking that controls the clutch and the brake so that an output shaft of the automatic transmission is braked by a braking force of the brake through the gears when the control unit determines that a braking device of the vehicle cannot normally apply braking forces to wheels despite that the vehicle needs to be braked.

摘要： Systems and methods for control of the delivery of contaminates are provided. A conveyor moves contaminate particles from a hopper into an airflow. The contents of a hopper at multiple time points within a sliding window of time are weighted with a scale. A processor applies linear regression to a data set comprising the time points as an independent variable and the weight measurements as a dependent variable, resulting in a determination of a line fitting the data set. A processor determines a current mass flow rate of the contaminate particles from the slope of the line. The processor determines an estimated change in the conveyor motor speed needed to achieve the target mass flow rate, the estimated change determined from a predetermined mapping of flow rates to motor speeds, the estimated change based on the current mass flow rate, the target mass flow rate, and a predetermined fraction.

摘要： A motor control method inputs one or more controlled variables or target values each representing a state of a motor to one or more node layers as an input value, and performs calculation in each of the one or more node layers to output one or more manipulated variables used for control of the motor and control the motor in accordance with the one or more manipulated variables. Each the one or more node layers has a plurality of nodes that execute calculations in parallel. Each of the plurality of nodes multiplies the input value by a coefficient specified for the corresponding node, and performs calculation using a function specified for the corresponding node and designating a multiplied value as an input variable to determine an output value.

摘要： A vehicle includes first and second electric machines constrained to rotate in unison and configured to power a common axle. A controller is programmed to, in response to activation of the vehicle, select one of the first and second speed sensors as a representative speed sensor, and, in reponse to the electric machines being in speed control, command speeds to the first and second electric machines based on a difference between a target speed of the electric machines and a measured speed of the representative speed sensor.

摘要： Support frames and rail cars include first and second side drive plates, first and second cross members connecting the respective ends of the side drive plates, third and fourth cross members connecting the side drive plates at a select distance from the first and second cross members, a coupling assembly situated at the first cross member and adapted to connect another rail car thereto, and first and second diagonal support members connected to the first cross member at an angle sufficient to substantially direct forces from the coupling assembly to the third cross member and side drive plates. The support frames and rail cars may be used for conveying bulk materials on a rail transport system.

摘要： Self-generated thermal stress evaluation concepts are described. In one embodiment, a system includes a computing device, a cooling system, such as fans, that draws heat away from the computing device, and a management controller. The management controller can sense a temperature in the computing device and compare it against a temperature profile. The temperature profile can specify one or more target temperatures in the computing device over time. Based on the comparison, the management controller can adjust a cooling capacity of the cooling system. The adjustment to the cooling capacity can be achieved by reducing the speed of the fans, for example, to raise the temperature in the computing device. Processing tasks can also be executed in the computing device and, in response to the detection of an error in the computing device, the management controller can record the error and a profile for the error for further evaluation.
