Optimized rotation of a drill string during sliding mode of directional drilling
An example method for optimized rotation of a drill string coupled to a drill bit and disposed within a borehole may comprise determining an angular velocity of at least part of the drill string. An angular velocity threshold to avoid static friction may also be determined. Additionally, a minimum input torque to apply to the drill string to maintain the angular velocity at or above the angular velocity threshold may be determined. The method may further include generating a control signal to a top drive motor based, at least in part, on the minimum input torque.

Method and control device for controlling a haptic accelerator pedal of a motor vehicle by means of a position control
A method and to a control device for controlling a haptic accelerator pedal in a motor vehicle includes displacing a pedal lever in an actuation direction between a rest position and a maximally actuated position. The pedal lever is configured to be excited by an actuator by exerting a counter force against the actuation direction to generate a haptically perceivable signal. A current position of the pedal lever relative to a current position of the actuator is determined outside the phases for generating the haptically perceivable signal, and the actuator is subsequently controlled in such a manner that the actuator actively follows a change in the determined position of the pedal lever. The positional control is configured to prevent interfering influences on the pedal lever by the actuator.

COOLING FAN SPEED CONTROL PROFILE
Adjusting a cooling fan speed control profile to account for system implementation factors, such as ambient temperature and usage history, can optimize power consumption and reduce the volume and variation of sound generated by shifts in fan speed in response to changes in system and component temperature. Adjusting a cooling fan speed control profile may include adjusting a maximum fan speed based on an ambient temperature or component temperature of the information handling system.

FORKLIFT
Provided is a forklift capable of recognizing an approximate weight of an object to be conveyed supported by a fork without adding special parts. A control unit includes a storage unit which stores load/time information indicating a relationship between a delay time required for an angle of rear wheels to reach an angle corresponding to an angle of the steering wheel and a weight of the object to be conveyed supported by the fork at that time, a delay time detection unit which detects the delay time required for a steering angle of the rear wheels to reach the angle corresponding to the angle of the steering wheel, and a weight identifying unit which identifies the weight of the object to be conveyed supported by the fork on the basis of the delay time detected by the delay time detection unit and the load/time information stored in the storage unit.
