Embodiments described herein provide active dampening of flexible modes of a UAV during flight operations. During operation of a UAV having a flexible airframe, the thrust and/or torque of the motor(s) coupled to propellers can induce flexing in the airframe that reduces the flight performance of the UAV. Measurements of a linear acceleration and/or an angular rate at a location proximate to the motor are performed, and flexible modes in the airframe of the UAV are identified based on the measurements. An operation of the motor(s) is modified based on the measurements to dampen the flexible mode.

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.

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.

Example implementations relate to virtualizing fan speed. For example, a system for virtualizing fan speed may include a server enclosure manager connected to a controller area network (CAN) bus, the server enclosure manager to regulate a speed of a fan in a server blade enclosure; and a CAN bus microcontroller connected to the CAN bus. The CAN bus microcontroller may receive a direct current (DC) voltage from an analog low-pass filter, determine a fan speed of the fan corresponding to the received DC voltage, and report the determined fan speed to the enclosure manager.

A servo motor controller capable of eliminating inconvenience that the position of a shaft or the like of a servo motor is detected or set erroneously due to influence of noise or the like is provided. A servo motor controller that detects Z-phase signals of an incremental-type encoder that detects rotation of a servo motor to perform driving control of the servo motor includes: a position detection unit that detects a reference position of a rotating shaft of the servo motor on the basis of the Z-phase signal of the encoder; a signal interval detection unit that measures intervals of a plurality of detected Z-phase signals; and an abnormality determination unit that determines that the Z-phase signal is abnormal when the interval measured by the signal interval detection unit is equal to or larger than a prescribed threshold.
