An electric motor controller system for modulating requested motor torque via oscillating the instantaneous torque, including a bi-stable torque controller; a proportional-integral (PI) velocity controller a proportional-integral-differential (PID) position controller; and sinusoidal zero-velocity table mapping.

Bi-stable, sub-commutated, direct-drive, sinusoidal motor controller for precision position control

A system having a damper with six or more indentations on alternating sides of the damper, where each indentation is open to an outer circumferential surface of the damper and extends over halfway through a width of the damper, and six or more slots, each slot open to an undulating inner circumferential surface of the damper and extending through the width of the damper.

Motor mount and damper

An aircraft including a wing system, a plurality of control surfaces, a camera mounted on a camera pod, and a control system. The camera pod is configured to vary the orientation of the camera field of view only in yaw, relative to the aircraft, between a directly forward-looking orientation and a side-looking orientation. The control system controls the control surfaces such that they induce a significant aircraft yaw causing an identified target to be within the field of view of the camera with the camera in the directly forward-looking orientation.

Unmanned aircraft turn and approach system

A shock resistant fuselage system includes first and second fuselage side walls, each of the first and second fuselage side walls having a plurality of guide posts, and a printed circuit board (PCB) rigidly attached to at least one of the first and second fuselage side walls, the PCB having a plurality of guide slots, each of the plurality of guide posts slideably seated in a respective one of the plurality of guide slots so that elastic deformation of the PCB is guided by the guide slots between the first and second fuselage side walls.

Mounting system for mechanical-shock resistant printed circuit board (PCB)

For use in determination of chain transmitted power, the combination comprising a tensioned chain having a succession of chain links with undulating edges; an idler supported to be driven in rotation by the chain, and having an undulating perimeter surface having a sine wave configuration and whose width dimension exceeds the width dimension between outermost chain surfaces; and certain of the chain undulating edges engaging portions of the idler undulating perimeter surfaces, whereby the chain changes direction as it travels lengthwise relative to the idler and rotatably drives the idler.
