A rigid-flexible coupling motion platform driven by a ball screw includes a base, a linear guide rail fixed to the base, a rigid-flexible coupling platform, a servo motor, a ball screw, a guide rail sliding block, a displacement sensor and a driving controller. The rigid-flexible coupling platform includes a frame and a workbench. The frame and the workbench are connected through a flexible hinge; the servo motor is configured to drive the ball screw; the workbench is connected with the ball screw; the frame is connected with the linear guide rail by the guide rail sliding block; the displacement sensor is configured to feed back the position of the workbench; and the driving controller controls the ball screw to drive the workbench to move according to different control modes. The advantages of the ball screw drive and the rigid-flexible coupling motion platform are fully combined, and the positioning precision of the platform is greatly improved.

A mechanism is provided for utilizing localized clusters within a mesh network to aid in tracking environmental factors associated with information handling systems in an environment having a large number of information handling systems installed. Sensors within each information handling system measure a variety of environmental factors, such as, for example, temperature (CPU, ambient, air inlet, air exhaust, system board, and the like), air flow through the information handling system, fan speed, and hardware utilization. The sensor-derived environmental information is provided to a lead local cluster node, which can provide local responses to environmental values exceeding thresholds. Lead nodes generate a mapping of the environmental factors and provide that mapping to a data center management server. The data center management server collates environmental mapping information to derive a data center-wide environmental mapping used by management personnel to make adjustments to balance load, reduce temperatures, and reduce energy usage.

A self-regulating fire pump unit which can be controlled to operate under required conditions for sourcing a fire protection system such as sprinklers. The fire pump unit can be operated in accordance with a control curve based on detected pressure and flow. The control curve can include: a) a first setpoint of rated total value of the system load for the pressure and the flow, b) a second setpoint of a minimum partial percentage of the rated total value of the pressure at an over-percentage of the rated total value of the flow, c) a path which maintains the rated total value of the pressure for all values of the flow up to the first setpoint, d) a path between the first setpoint and the second setpoint, e) a path from the second setpoint which limits values of the pressure for values of the flow greater than the second setpoint.

The present disclosure provides a method for automatically optimizing power consumption. The method includes: (S1) a baseboard management controller determines whether system information is correct or not after powered on. If correct, further proceeding the method. If not correct, stopping further proceeding the method. (S2) the baseboard management controller periodically detects the surface temperature and the internal temperature of the essential element with a first loop cycle and determines whether the surface temperature or the internal temperature is higher than a preset temperature. (S3) If the surface temperature or the internal temperature is higher than the preset temperature, performing a PID adjustment to the fan rotation speed according to the surface temperature or the internal temperature of the essential element. If the surface temperature or the inner temperature is not higher than the preset temperature, performing a stepwise adjustment to the fan rotation speed according to current environment temperature.

A method and system for activating and canceling a first or second turn signal indicator for an R/C vehicle are provided. The method may include determining that the R/C vehicle is stationary and reading a rotation of a steering input to a stationary activation threshold. In addition, the method may include activating the turn signal indicator on a side of the R/C vehicle and setting an active turn signal indicator to on. Further actions in the method may involve determining that the R/C vehicle is in motion and reading a rotation of the steering input to a moving initiation threshold. Still further actions may include reading a rotation of the steering input in another direction to a moving cancellation threshold and deactivating the first or second turn signal indicator and setting the active turn signal indicator to off.
