Axial flow devices using rigid spiral band profiled blade catenaries attached variably along and around an axially elongated profiled hub, of axially oriented profile section sequences 75 mapped relative to truncated cones-of-generation. Upon rotation and lubricity-masked progression through axial planes-of-shear, this time-domain sequence travels in 2-dimensional axial-datum-plane-relative path-excursions and ejects frictional adhesions via anguillar reverse vortex street thrust due to an after-body accelerating wave shape-sequence 48. This guides bound vortex pressures at linear path-velocity substantially parallel to the collective plane-of-shear, conferring higher differential pressures through path-vector-addition, improved force-vector orientation, extended laminar flows, lower form drag and tip vorticity. As a wind turbine, path-vectors are added to inflow, ducting an increased mass flow inward for increased power extraction per diameter. As a propeller, path-vector-subtraction guides the wave front flight-path-transverse, allowing higher flight velocities and improving thrust-per-torque through enhanced force vectors and mass flow rates.

In one embodiment, the sensor is a strain gage responsive to tension and compression of at least a portion of the body of the force sensor and the electrical characteristic of the strain gage that is monitored is electrical resistivity. In another embodiment, the sensor is responsive to strain and stress of at least a portion of the body, and the electrical characteristic being monitored is inductance or hysteresis loss.

An industrial robot that has uses a simulated force vector to allow a work piece held by the robot end effector to be mated with a work piece whose location and orientation is not precisely known to the robot. When the end effector makes contact with the location and orientation in which the other work piece is held the robot provides a velocity command to minimize the force of the contact and also provides a search pattern in all directions and orientations to cause the end effector to bring the work piece it is holding in contact with the other work piece. The search pattern and the velocity command are continued until the two work pieces mate.

A method and system are provided for controlling the simulated interfacing of a controlled first body, for example a tool, with a second body while providing haptic feedback to a user on such interfacing. Selected representations of the first and second bodies are stored in a memory of a processing apparatus and are used by such apparatus to control simulated movement of the first body relative to the second body in response to a user controlled haptic interface device. Collisions between the first and second body are detected, including the position on each body of each collision, the direction of the collision and the force of the collision, and this information is converted for each collision into a force vector on the first body which is fed back as a corresponding force vector to the interface device, and thus to the user. A feature of the invention is storing a point cloud representation of at least one of the bodies, which point cloud representation is utilized in the simulations. The representations may also be an implicit equation representation, a binary space tree partition representation or the like. A niceness factor may also be utilized in determining force feedback as may a guide zone around at least a portion of one of the bodies which, for example, may be utilized to provide a snap-fit. Other features are also provided.
